Answer:
Remember that for a triangle rectangle we have the Pythagorean's theorem, it says that the square of the hypotenuse is equal to the sum of the squares of the catheti.
Then if the catheti of a triangle rectangle are A and B, and the hypotenuse is H, we have:
H^2 = A^2 + B^2
In the smaller triangle we can see that:
H = 10
A = 6
Then:
10^2 = 6^2 + B^2
100 = 36 + B^2
100 - 36 = B^2
64 = B^2
√64 = B = 8
And we know that the perimeter of a triangle is equal to the sum of the lengths of it's sides, then the perimeter of the smaller triangle is:
P = 10 + 6 + 8 = 24
Now we know that the triangles are similar and related by a factor of 4/3, then each measurement of the larger triangle will be equivalent to 4/3 times the corresponding measurement of the smaller triangle, then if the measures of the larger triangle are A', B', and H', we can write these as:
A' = (4/3)*A = (4/3)*6 = 8
B' = (4/3)*B = (4/3)*8 = 10.67
H' = (4/3)*H = (4/3)*10 = 13.33
Then the perimeter of the larger triangle is:
P' = 8 + 10.67 + 13.33 = 32
Which of the following are written in point-slope
form?
a) y + 2 = -9(x + 3)
b) y - 7 = 5(x + 1)
c) x - y = -3
d) y = -x +6
Answer:
y + 2 = -9(x + 3) and y - 7 = 5(x + 1)
Step-by-step explanation:
[tex]\text{Point-Slope form is:}\\\\y-y_1=m(x-x_1)\\\\\text{m - slope}\\\\(x_1,y_1) \text{ - a point}[/tex]
----------------------------------------
[tex]\text{Options A and B are written in point-slope form.}\\\\\\y+2 =-9(x+3)\\\\\text{The slope is -9 and the point used is (-3, -2).}\\\\\\y-7=5(x+1)\\\\\text{The slope is 5 and the point used is (-1, 7).}[/tex]
-----------------------------------------
[tex]\text{Option C is written in Standard Form.}\\\\Ax+By=C\\\\\\\text{Option D is written in Slope-Intercept Form.}\\\\y=mx+b\\\\\text {m - slope}\\\\\text{b - y-intercept}[/tex]

The height of a skydiver jumping out of an airplane is given by n = -16t^2 + 3200. How long will it take the skydiver to reach the ground? Round to the nearest tenth of a second.
Answer:
0 = -16t² + 3200 → 16t²= 3200 → t² = 200 → t = 10√2 s ≈ 14 s
The time taken by the skydiver to reach the ground is 14.1 second.
What is the solution of a quadratic equation?The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.
Given that, the height of a skydiver jumping out of an airplane is given by n = -16t² + 3200.
Here, n=0
-16t² + 3200=0
-16t²=-3200
t²=200
t=√200
t=14.14
t=14.1 second
Therefore, the time taken by the skydiver to reach the ground is 14.1 second.

Step-by-step explanation:
Area of Square:
A= LXW= 10x10= 100 sq cm
Area of Circle=
A=πr²
Radius= D/2= 10/2= 5 cm
A=3.14(5²)

Over the past few years, Mitchell has made 99 trips to visit the amusement park. He drove 6,870.1 kilometers in all. To the nearest hundredth of a kilometer, how far did Mitchell drive on each trip?
Answer:
69.39 kilometers
Step-by-step explanation:
total kilometres driven on each trip = total kilometres driven on all trips / total number of visits
6,870.1 / 99 = 69.394949
To the nearest hundredth means we are rounding off the third number after the decimal point. The second number after the decimal is the hundredth. The third number is less than 4, so zero would be added to the preceding number
69.39 kilometers
cos B =
tan B =
sin B =
The three main trig functions are sine (written as sin), cosine (written as cos), and tangent (written as tan).
Sine of an angle = the length of the side opposite (aka across) the angle / the length of the hypotenuse
Cosine of an angle = the length of the side adjacent (aka the side next to which isn't the hypotenuse) to the angle / the length of the hypotenuse
Tangent of an angle = the length of the side opposite of the angle / the length of the side adjacent to the angle.
The acronym to remember this is SOHCAHTOA
SOH | CAH | TOA
SOH means sin(x) = opposite/hypotenuse
CAH means cos(x) = adjacent/hypotenuse
TOA means tan(x)= opposite/adjacent
cosB = length of adjacent side/length of hypotenuse = 7/25
tanB = length of opposite/length of adjacent = 24/7
sinB = length of opposite/length of hypotenuse = 24/25
if a probability of a player a is 0.3 then the probability of a player b is how much?
Answer:
0.7
Step-by-step explanation:
The total probability is equal to 1
To find the probability of player b we take the probability of player a and subtract it from the total probability of 1
Hence 1-0.3=0.7
Answer:
0.7
Step-by-step explanation:
→ Minus 1 from the probabilities as all probabilities add up to 1
1 - 0.3 = 0.7

what are the solutions to the equation 3x²+15x=18
Answer:
x = 1 or x = −6
Step-by-step explanation:
Step 1: Subtract 18 from both sides.
3x2+15x−18=18−18
3x2+15x−18=0
Step 2: Factor left side of equation.
3(x−1)(x+6)=0
Step 3: Set factors equal to 0.
x−1=0 or x+6=0
x=1 or x=−6
Does this triangle have a hypotenuse about 39 feet long
Answer:
hypotenuse is about 33 ft long
Step-by-step explanation:
a^2+b^2=c^2
a= 30
b=14
30^2+14^2= 1096 =c^2
[tex]\sqrt{1096}[/tex]=c
33.1=c
hypotenuse is about 33 ft long
Answer:
No, the Hypotenuse is 33.11
Step-by-step explanation:
The formula for finding a hypotenuse is:
[tex]\sqrt{x^2+y^2}[/tex]
x=30 and y=14 here
[tex]x^2=900[/tex]
[tex]y^2=196[/tex]
[tex]x^2+y^2= 1,096[/tex]
[tex]\sqrt{1,096} = 33.11[/tex]
So it would be about 33, not 39

Suppose a video store charges nonmembers $4 to rent each video. A store membership costs $21 and members pay only $2.50 to rent each video. For what number of videos is the cost the same?
Answer:
You need to rent
14
videos, and you'll pay the same amount for both. Renting
15
will make the membership a better method of payment.
Explanation:
We can create an equation. Say the number of videos you rent is given by
n
. We can write that, if we rent
n
videos without membership, we'll have to pay
4
n
. If we rent the same amount of videos with membership, we'll have to pay
21
+
2.5
n
.
To find the value of
n
such that the amount you pay without membership is equal to the amount you pay with, we write:
4
n
=
21
+
2.5
n
1.5
n
=
21
n
=
21
1.5
n
=
14
You need to rent
14
videos, and you'll pay the same amount for both. Renting
15
will make the membership a better method of payment.

Answer:
y = 2x + 8
Step-by-step explanation:
Recall that two parallel lines have the same slope.
Thus, if we begin with y = 2x - 4, we know that this new line through (-1, 6) will also have slope 2.
Starting from the slope-intercept form y = mx + b, we substitute 2 for m, -1 for x and 6 for y:
6 = 2(-1) + b
and solve for the new y-intercept, b:
6 = -2 + b, or
b = 8
Then the new line has the equation y = 2x + 8

Jonathan was 45 inches tall when he started kindergarten. He grew an average of 2.5 inches every year. Jonathan is now 62.5 inches tall. Which equation can be used to find how many years ago Jonathan started kindergarten, and how many years ago was it?
A. (45 + 62.5) ÷ 2.5 = x 7 years
B. 2.5x + 45 = 62.5 7 years
C. (45 + 62.5) ÷ 2.5 = x 43 years
D. 2.5x + 45 = 62.5 43 years
Answer:
B; 2.5x + 45 = 62.5
Step-by-step explanation:
Since the current height is 62.5, and the starting height is 45, then all you have to do is subtract 45 from 62.5, then divide that by 2.5 to get your answer, which should be 7 years.
Hopefully this helps- let me know if you have any questions!
