Answer:
180-60 = 120 if triangle is not equilateral it cannot be isosceles then depending where the angles are they will show 60,60,60 if equilateral
For isosceles it would need to be 58 61 61 as 60, 60,60 cannot be isosceles.
Vectors 60 if right angled triangle = 90-60 = 30
So angles = 30 and 90 degree or just 120 if angle theta is a vector as explained below.
Step-by-step explanation:
Statement: If two vectors are represented by the sides of a triangle both in magnitude and direction taken in order, the resultant sum of the vectors is given by the closing third side of the triangle taken in the reverse order both in the magnitude and direction
Find the lowest common denominator of the following fractions.5/n-2 and n+2/ n^2-4 n - 2 n2 - 4 (n - 2)(n2 - 4)
Answer:
(n-2)(n+2)
Step-by-step explanation:
The denominator of the second fraction is the difference of squares, so can be factored using the formula for that.
(n^2 -4) = (n -2)(n +2)
Now, you will note that the second fraction has a numerator that is equal to one of the factors in the denominator. In other words, the whole fraction can be simplified to ...
(n +2)/((n +2)(n -2)) = 1/(n -2) . . . . with the restriction n≠-2
This reduced form of the fraction has the same denominator as the first fraction, so you can say that the lowest common denominator is that: (n -2).
If there is some reason you don't want to reduce the second fraction, the lowest common denominator will be (n -2)(n +2).
At the Laika Boss Kennel Club, there are 15 dogs that are hairy or small, 2 dogs that are hairy and small, and 9 dogs that are small. How many dogs are hairy?
Answer:
8 hairy dogs
Step-by-step explanation:
There are 15 dogs that are hairy or small
2 that are hairy and small
9 that are small
small - ( hairy and small) =just small
9 -2 = 7 small only dogs
Take the total dogs minus the small dogs minus the small and hairy dogs to find the hairy dogs
15 - 7 - 2 =6
There are 6 hairy dogs
2 small and hairy dogs
7 small dogs
total 15 dogs
If we want the total of the hairy dogs
2 small and hairy + 6 hairy = 8 hairy dogs
if you have blue, green ,yellow and red what is the probability of spinning red twice
Answer:
2% chances
Step-by-step explanation:
The probability of spinning red is 2 out of 4 because since there is 4 colors and spinning a color twice it can't happen.
How do i know
1: Divide the number of color by the number of outcomes
2: So since there are 4 colors and twice means 2.
3: 4 divided by 2 = 2% chances.

]solomon needs to justify the formula for the arc length of a sector. which expression best completes this argument? the circumference of a circle is given by the formula c=pi * d , where d is the diameter. because the diameter is twice the radius, c= 2 * pi * r. if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to 360°/n° the arc length of each sector is the circumference divided by the number of sectors, or _____. therefore, the arc length of a sector of a circle with a central angle of n° is given by 2*pi*r*n/360 or pi*r*n/180 . a. 2*pi*r/270/n b. 2*pi*r/360/n c. 2*pi*r/180/n d. 2*pi*r/90/n
Answer:
[tex]\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}[/tex] best completes this argument
Step-by-step explanation:
Circumference of circle =[tex]\pi \cdot d[/tex]
Where d is the diameter of circle
We are given that if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to [tex]\frac{360^{\circ}}{n^{\circ}}[/tex]
So, Number of sectors = [tex]\frac{360^{\circ}}{n^{\circ}}[/tex]
The arc length of each sector is the circumference divided by the number of sectors
[tex]\Rightarrow \frac{\pi \cdot d}{\frac{360^{\circ}}{n^{\circ}}}[/tex]
Diameter d = 2r (r = radius)
[tex]\Rightarrow \frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}[/tex]
Option b is true
Hence[tex]\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}[/tex] best completes this argument

Given cos = 7/25, where is an angle in standard position terminating in
quadrant IV, what is the value of tan ?
Answer:
tanΘ = - [tex]\frac{24}{7}[/tex]
Step-by-step explanation:
Given
cosΘ = [tex]\frac{7}{25}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]
The right triangle has sides 7, 24, 25 ← Pythagorean triplet
with adjacent = 7 and opposite = 24
Since position is in fourth quadrant then tanΘ < 0 , thus
tanΘ = - [tex]\frac{24}{7}[/tex]

Explain why you cannot use the Distributive Property to evaluate an expression in the form of sin(a + b). Please illustrate with an example along with your explanation.
Answer:
The distributive property is to multiply the outside of a parenthesis by each term inside, for example:
[tex]x(y+z)=xy+xz[/tex]
this cannot be done with the trigonometric functions such as the sine.
An example of this:
let's prove that we don't get the correct result using the distributive property in the following expression:
[tex]sin (\pi+\pi/2)[/tex] ≠ [tex]sin(\pi)+sin(\pi/2)[/tex]
We add the elements in the parentheses on the left side:
[tex]sin(3\pi/2)[/tex] ≠ [tex]sin(\pi)+sin(\pi/2)[/tex]
this are known values of the sine function:
[tex]sin(3\pi/2)=-1[/tex]
[tex]sin(\pi)=0[/tex]
[tex]sin(\pi/2)=1[/tex]
substituting these values we will get that:
-1 ≠ 0 +1
-1 ≠ 1
Thus we notice that we don't get the correct result using the distributive property.
The correct way to express the angle sum in the sine function is:
[tex]sin(a+b)=sin(a)cos(b)+sin(b)cos(a)[/tex]

Identify the transformation that results in an image that's not congruent to the pre-image. Question 9 options: A) Rotation B) Translation C) Dilation D) Reflection
Answer:
C) Dilation
Step-by-step explanation:
Rotation is simply rotating an object, therefore, the size and shape remain the same.
Translation is moving the object across the plane, and again, the size and shape will stay the same.
Reflection is reflecting a shape across a certain line. It will still keep its size and shape.
However, dilation is enlarging or shrinking a shape. This means that the shape will change size, but not shape. A dilation of a shape will be similar, but not congruent, to it.
Hope this helps :) Feel free to ask me any questions!
Answer:
C
Step-by-step explanation:
The cost of renting an apartment can be modeled by the function C(m)=900m+1400, where C(m) is the cost in dollars for m months of living in the apartment. State the meaning of the slope and y-intercept of this function with respect to the costs associated with renting the apartment.
Answer:
On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.
Step-by-step explanation:
This function is linear, which means that it increases at a steady rate and has the following form:
[tex]y(x) = a*x + b[/tex]
Where "a" is the slope or the rate at which "y" changes for every change in "x". While "b" is the number at which the function crosses the "y" axis.
On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

Which numbers are solutions to the inequality
– 3x-3<6? Select all that apply.
A. -5
B. -4
C. 0
D. 2
E.4
Answer:
C. 0
D.2
E.4
Step-by-step explanation:
To know which numbers are solutions to the inequality, we will follow the steps below:
-3x -3 < 6
add 3 to both-side of the inequality
-3x -3 + 3 <6+3
-3x < 9
Divide both-side of the inequality by -3
-3x/-3 >9/-3
whenever we are dividing both-side of inequality by a negative number, the inequality sign will change
x > -3
all values of x that are greater than -3 will satisfy the inequality
They are 0, 2 and 4
check the solution:
for x=0
-3x -3 < 6
-3(0) -3 < 6
-3 < 6
for x = 2
-3x -3 < 6
-3(2) -3 < 6
-6 -3 < 6
-9< 6
for x = 4
-3x -3 < 6
-3(4)-3 < 6

find the equation that going through these points.
urgent!! will give the brainliest
Answer:
The correct answer is y = -3x + 1.
Step-by-step Explanation:
First, you need to use the point slope formula to determine the slope. This is determined by the formula of the second y-coordinate (the y-coordinate in the second ordered pair) minus the first y-coordinate (the y-coordinate in the first ordered pair).
When subtracting the two values, you receive 7 - -5. You would use the KCC (keep, change, change) rule and keep positive 7, change the minus to addition, and turn negative 5 into positive 5. This gives you a value of 12.
Then, you use the same formula layout for the x-coordinates. Take the x-coordinate in the second ordered pair and subtract the x-coordinate in the first ordered pair to get -2 - 2 = -4.
Finally, to determine the slope, divide 12 and -4 to get -3.
Then, to get the y-intercept placed at the end, you will need to substitute the coordinate values from one of the ordered pairs into the equation y = -3x + b. I chose to use the first ordered pair, so:
-5 = -3(2) + b (Multiply the slope by x to earn the new value)
-5 = -6 + b (Add the -6 to the -5 to isolate the b)
1 = b (b = 1) (Learn that b = 1)
Your final equation will be y = -3x + 1.
Answer:
The equation is y = -3x + 1.
Step-by-step explanation:
First, you have to find the gradient of the equation using the formula :
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
Let (x1,y1) be (-2,7),
Let (x2,y2) be (2,-5),
[tex]m = \frac{ - 5 - 7}{2 - ( - 2)} [/tex]
[tex]m = \frac{ - 12}{4} [/tex]
[tex]m = - 3[/tex]
Next, we have to use the slope-form equation y = mx + b where m is gradient and b is constant. So we have to find the value of c by substituing any coordinates into the equation :
[tex]y = - 3x + b[/tex]
Let x = 2,
Let y = -5,
[tex] - 5 = - 3(2) + b[/tex]
[tex] - 5 = - 6 + b[/tex]
[tex]b = 6 - 5[/tex]
[tex]b = 1[/tex]
On November 1, the balance of a credit card account is $2,835.63. There was a payment of $230.00 made on
November 12 as well as a new purchase for $121.36. On November 25, a second payment of $25.00 was made. The
annual interest on the account is 17.65%. Determine the finance charge for the account using both the average daily
balance and the adjusted balance methods. Which method would be more advantageous to the cardholder? Justify
your reasoning. Answer in complete sentences.
Answer:
The adjusted balance is generally the most advantageous billing method for the cardholder since the financial charges are lower ($39.20 < $40.07). This happens because interest is only charged on the final monthly balance, and cardholders can decrease that balance during any day of the billing cycle.
Step-by-step explanation:
November 1: balance $2,835.63
November 12: $230 payment
November 12: $121.36 purchase
November 25: $25 payment
annual interest 17.65%
average daily balance = {(11 x $2,835.63) + [13 x ($2,835.63 - $230 + $121.36)] + [6 x ($2,835.63 - $230 + $121.36 - $25)]} 31 days = ($31,191.93 + $35,450.87 + $16,211.94) / 30 days = $82,854.74 / 30 days = $2,761.82
financial charge = ($2,761.82 x 30 x 17.65%) / 365 = $40.065 ≈ $40.07
adjusted balance = $2,835.63 - $230 + $121.36 - $25 = $2,701.99
financial charge = $2,701.99 x 17.65% x 30/365 = $39.197 ≈ $39.20
