The angle 01 is located in Quadrant IV, and sin(01) = -24/ 25
What is the value of cos(01)?
Answer:
[tex] \frac{7}{25} [/tex]
Step-by-step explanation:
We can solve that using this identity,
[tex] \sin {}^{2} (x) + \cos {}^{2} (x) = 1[/tex]
plug in -24/25 from x in sin
[tex] \sin {}^{2} ( \frac{ - 24}{25} ) + \cos {}^{2} (x) = 1[/tex]
[tex] \sin( \frac{576}{625} ) + \cos {}^{2} (x) = 1[/tex]
[tex] \cos {}^{2} (x) = 1 - \frac{576}{625} [/tex]
[tex] \cos {}^{2} (x) = \frac{49}{625} [/tex]
[tex] \cos(x) = \frac{7}{25} [/tex]
Since cos is positve in quadrant 4, the answer is 7/25.
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
then
Sin(Ф) = - [tex]\frac{24}{25}[/tex]
find the angle Ф
Ф = arcSin ( - [tex]\frac{24}{25}[/tex] )
Ф = -73.739795°
so an angle measured clock wise from x axis at zero°
now use cos(Ф) = x/ 25 to find x
25* cos( -73.739795°) = x
7 = x :o wow... exactly? :P nice
cos(Ф) = 7/25 I think that's what they wanted to know
also I noted my calculator tried to find the fraction of 0.2800000049 and couldn't, but then I just put in 0.28 and it found that to be 7/25 :0 so I think we're spot on :)
a polygon has perimeter 15 units.it is dilated with a scale factor of 3/5.what is the perimeter of its image
Given what we know, we can confirm that the perimeter of the image is 9 units.
Perimeter and Scale factor.To calculate the perimeter of a shape, we must add the length of all of its sides. When we dilate a shape, we multiply each of its sides by our scale factor.Our scale factor is [tex]\frac{3}{5}[/tex], which corresponds to 0.6 in decimal form Taking the sum of 15 as the perimeter of the preimage and multiplying by 0.6 gives us the perimeter of the image which is 9 units.Therefore, given that [tex]15units * \frac{3}{5} = 9 units[/tex], we can confirm that the perimeter of the image is 9 units.

Similar = Yes, they are similarHow: AA similaritySimilarity statement: triangle HGF ~ triangle HMNThe ~ mark means "similar"
=====================================================
The red angle markings tell us which angles are congruent to one another. We have these two pairs of congruent angles
angle H = angle H (both triangles unfortunately reuse H) by the single arc markingangle G = angle M, by the double arc markingsBecause we have two pairs of congruent angles, we use the AA similarity theorem. AA stands for angle angle. We could use three pairs, but two pairs is the minimum needed for similarity statements.
-----------
To figure out what goes in the third answer box, note how the order HGF is given to us. The order is important.
We have H first, G second, F third.
H being first, and it having a single arc, means that whatever has a single arc on the other triangle must be first. That would be H. Unfortunately they reuse angle H which makes things confusing a bit.
G is second in HGF, and G has the double arc marking. Note how M also has this double arc marking. Therefore we have M second in the answer. So far we have HM as part of the third answer.
The only thing left is N. Therefore, we have triangle HMN as the answer for the third box.
Put another way, we have these pairings:
H (single arc mark) = H (single arc mark)G (double arc mark) = M (double arc mark)F (no marking) = N (no marking)This is why the order is important. So we can see how the angles pair up in the order that they do.
This is why triangle HGF is similar to triangle HMN.
We can write that as triangle HGF ~ triangle HMN
The ~ mark means "similar"
We don't have enough information to prove that the triangles are congruent or not. So we cannot say [tex]\triangle HGF \cong \triangle HMN[/tex]. Your teacher made a typo when using the congruence symbol [tex]\cong[/tex]
Instead, it should be [tex]\triangle HGF \sim \triangle HMN[/tex]

Step-by-step explanation:
1. The vertex is the x coordinate of the lowest point of the parabola. The lowest possible point is (1,-2). So our vertex is 1.
2. The axis of symmetry passes through the vertex so the axis of symmetry is at the line x=1 .
3. X intercepts are what are the x values when y =0. The x intercepts are -2 and 4.

Step-by-step explanation:
Answer: Rounded to the nearest $10 he would have to invest $830
Step-by-step explanation: While I am not completely familiar with this sort of math I am still relatively confident that I got the correct answer. Using the formula A = Pe^rt. First we can convert the percentage to a decimal so it can be used efficiently in the formula. So r = 3.1/100 which in turn equals 0.031 which is our decimal. Now we can simply input our information into the formula for our answer so follow along
A = 830 * e ^(0.031 * 6)
A = 830(2.718281828459045)^(0.186)
A = 999.67
And of course this is not exactly $990 because the question stated to round the original investment amount to the nearest 10 dollar. This should be your answer and if you have any other questions about this please do not hesitate to reach out :)

On Friday, Carlotta had 6/8 of her paper left to write. She wrote 2/6 of the paper on Saturday and ¼ of the paper on Sunday. At the end of the weekend, what fraction of her paper does Carlotta have left to write?
Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
Skills needed: Fraction Subtraction, Least Common Denominator (LCD)
1) [tex]\frac{6}{8} - \frac{2}{6} - \frac{1}{4}[/tex] is the operation you would do.
--> You would do this because, Carlotta has [tex]\frac{6}{8}[/tex] of the paper left, and does one fraction amount ([tex]\frac{2}{6}[/tex]) on Saturday & does another fraction amount ([tex]\frac{1}{4}[/tex]) on Sunday.
--> Using subtraction is the best way
2) Now, we need to figure out the Least Common Denominator for all 3 fractions.
8,6,4 are the denominators.
The lowest number that is a factor of all them is 24.
So, it would then become [tex]\frac{18}{24} - \frac{8}{24} - \frac{6}{24}[/tex]
This would become: [tex]\frac{18-8-6}{24}[/tex] (18-8-6 = 4)
So then: [tex]\frac{4}{24}[/tex] is your answer.
This simplifies into [tex]\frac{1}{6}[/tex].

In this experiment, you will be using two coins as a simulation for a real-world compound event.
Suppose that a family has an equally likely chance of having a cat or a dog. If they have two pets, they could have 1 dog and 1 cat, they could have 2 dogs, or they could have 2 cats.
1. What is the theoretical probability that the family has two dogs or two cats?
A dog or a cat will have a 50/50 chance of being adopted. There are three options: 50 percent for one dog and one cat, 25 percent for two dogs, and 25 percent for two cats. Adding the probabilities of finding two of the same dogs gives you a 50 percent shot.
2. Describe how to use two coins to simulate which two pets the family has.
You will have two fair sided coins if you used two coins to simulate the potential results of the family's dogs. Each coin will have one side with a dog and one with a cat (or heads and tails, where you would assign each pet a side of the coin).
3. Flip both coins 50 times and record your data in a table like the one below.
Result Frequency
Heads, Heads 15
Heads, Tails 9
Tails, Heads 19
Tails, Tails 7
Total 50
4. Based on your data, what is the experimental probability that the family has two dogs or two cats?
22/50.
5. If the family has three pets, what is the theoretical probability that they have three dogs or three cats?
50%.
6. How could you change the simulation to generate data for three pets?
You could add another coin.

The probability of the family having two dogs or two cats is 1/2 or 50%.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The theoretical probability of the family having two dogs or two cats can be calculated as follows:
P(D) be the probability of having a dog
P(C) be the probability of having a cat.
Since the family has an equally likely chance of having a cat or a dog, we have:
P(D) = 1/2 and P(C) = 1/2
The probability of having 2 dogs is:
P(D) x P(D) = (1/2) x (1/2) = 1/4
The probability of having 2 cats is:
P(C) x P(C) = (1/2) x (1/2) = 1/4
The theoretical probability of the family having two dogs or two cats is:
P(2 dogs or 2 cats).
= P(2 dogs) + P(2 cats)
= 1/4 + 1/4
= 1/2
Thus,
The probability of the family having two dogs or two cats is 1/2 or 50%.
