x=17 - hope this helps!
To solve this we are using the Pythagorean Theorem which is c^2=a^2+b^2.

In this case the c (hypotenuse) is x. Our equation will look like this:

x^2=15^2+8^2
x^2=225+64
x^2=289
We do the square root to undo ^2
x = 17

Mary owns 13 shares of a certain stock. Yesterday the value of each share went up by 4 dollars. What was the total change in value of her shares?

Answers

Answer: +52

Step-by-step explanation:

From the question, we are informed that Mary owns 13 shares of a certain stock and that the value of each share went up by 4 dollars.

The total change in value of her shares will be gotten by multiplying the number of shares that Mary has by 4. This will be:

= 13 × 4

= 52

What is the mathematical
representation of 20P4?

Answers

the answer for 20p4 is c

The mathematical representation of 20P4 is [tex]^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]. so option C is the correct.

How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?

We can use combinations for this case,

The Total number of distinguishable things is m.

Here, Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in total of

[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]

If the order matters, then each of those choice of k distinct items would be permuted k! times,

So, total number of choices in that case would be:

[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]

This is called permutation of k items chosen out of m items (all distinct).

We have to find the mathematical representation of 20P4.

[tex]^{20}P_4[/tex]

here, m = 20

k = 4

Now substitute;

[tex]^mP_k = \dfrac{m!}{ (m-k)!}\\\\^{20}P_4 = \dfrac{20!}{ (20-4)!}\\\\^{20}P_4 = \dfrac{20!}{ (16)!}\\\\\\^{20}P_4 = \dfrac{20 \times 19 \times 18 \times 17 \times 16!}{ (16)!}\\\\\\^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]

Hence, the mathematical representation of 20P4 is [tex]^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]. so option C is the correct.

It would be a=3 b=3 c=5

Answer:

the second option, a=3 b=3 c=5

Step-by-step explanation:

first I would change them both into an improper fraction:

9/2 divided by 5/4

dividing is the same thing as mulitiplying by the reciprocal of the second number. so you would mulitply 9/2 x 4/5 = 36/10 and then you simplify back to a mixed number 3 6/10, 6/10 can be reduced so the final answer is 3 3/5.

The points A , B and C lie on the line m . They are collinear.

The points D , B and E lie on the line n . They are collinear.

There is no line that goes through all three points A , B and D . So, they are not collinear.

X - 11 < 7
Please help✨✨

Answers

x menos 11 menor que 7. .............................

Answer:

x < 18

Step-by-step explanation:

We have an inequality and are asked to solve.

To solve, we need to isolate x or by other means get x by itself.

X - 11 < 7

Add 11 to both sides :

x < 18

Now you could ask whether the inequality sign would change, no, this would only happen when you divide by a negative number.

Solve for b.
3-2(b-2)=2-7b3−2(b−2)=2−7b

Answers

Step-by-step explanation:

3 - 2(b - 2) = 2 - 7b

To solve this first distribute -2 to (b - 2)

3 + (-2b + (-2) x -2) = 2 - 7b

when we simplify this it becomes:

3 + (-2b + 4) = 2 - 7b

We take (-2b + 4) out of the parenthesis:

3 - 2b + 4 = 2 - 7b

Now simplify again.

7 - 2b = 2 - 7b

Now send all the b's to one side and constants on the other.

7 - 2 = -7b +2b

5 = 5b

b = 1

The height, h, of a stomp rocket (propelled by a short blast of air) above the ground after t seconds is given by the equation h(t)=5+100t−16t2. Here is a graph that represents h.
1. What does the 5 in the equation represent?



2. What does 100t in the equation mean in terms of the rocket?



3. Approximately when does the rocket hit the ground?



4. What domain makes sense for the function in this context?

Answers

Answer:

Given equation and the graph of it:

h(t) = 5 + 100t − 16t²

1. What does the 5 in the equation represent?

5 represent a height of the release of the rocket

2. What does 100t in the equation mean in terms of the rocket?

100t is determining the maximum height that the rocket can reach

3. Approximately when does the rocket hit the ground?

As per the graph it is after 6.3 seconds it was launched

4. What domain makes sense for the function in this context?

Domain of the function is:

0 ≤ t ≤ 6.3

This is the time the rocket is in the air until it hits the ground

Answer: it will hit the ground around 6.2 seconds

The domain is 0 ≤ t ≤ 6.3
