Answer:

3 and 17

7 and 13

Step-by-step explanation:

Three odd numbers add up to 25

This means that

$x + y + z = 25$

One of the numbers is 5

Using $z = 5$

We have that:

$x + y + 5 = 25$

$x + y = 20$

Then

We need to find two prime numbers which add to 20.

The prime numbers are:

2, 3, 5, 7, 11, 13, 17, 19, ...

So the possible options are:

3 and 17

7 and 13

Answer the 3 screenshotted questions below. 30 points!

Answer:

13. $36a^2b^4$ π

14. $16x^3y^4$ π

15. $-\frac{c^3}{4a^7b^3}$

Step-by-step explanation:

13.

A = π * $r^2$

r = $6ab^2$

A = π* $(6ab^2)^2$

A = π * $(6ab^2)(6ab^2)$

A = π * $36a^2b^4$

A = $36a^2b^4$ π

14.

V = π * $r^2$ * h

r = $2x$

h = $4xy^4$

V = π * $(2x)^2$ * $4xy^4$

V = π * $4x^2$ * $4xy^4$

V = π * $16x^3y^4$

V = $16x^3y^4$ π

15. $\frac{3a^{-4}b^2}{-12a^3b^5c^{-3}}$ = $-\frac{c^3}{4a^7b^3}$

$\frac{3a^{-4}b^2}{-12a^3b^5c^{-3}}$

$\frac{a^{-4}}{-4a^3b^5c^{-3}}$

$\frac{b^2}{-4^{3+4}b^5c^{-3}}$

$\frac{b^2}{-4^7b^5c^{-3}}$

$\frac{1}{-4a^7b^{5-2}c^{-3}}$

$\frac{1}{-4a^7b^3c^{-3}}$

$\frac{c^3}{-4a^7b^3}$

$-\frac{c^3}{4a^7b^3}$

Hope this helps!

Which of the following best describes the graph above?

Maru [420]

Answer: C

Step-by-step explanation:

We know that a relation is any set of ordered pairs, but a function is when there is only one y value for x value.

So, basically, if a graph is a function, it is a relation as well.

Let’s check if this is a function.

We can use the vertical line test- if we draw a vertical line through any point on the graph and it only intersects one point, it is a function

In our case, it passes the vertical line test.

Therefore, it is both a function and a relation, which corresponds to letter C.

Hope this helps! :)

the value in dollars, v (x), of a certIN TRUCK AFTER X years is represented by the equation v(x) = 32.500 (0.92)^X. theo the nea

fenix001 [56]

Answer:

Answer: The truck is worth of $27508 after 2 years.

Step-by-step explanation:

Since we have given that

The value in dollars v(x), of a certain truck after x years is represented by the equation :

We need to find the price of the truck after 2 years,

so, x= 2

So, we put the value of x = 2 in the above equation:

Hence, the truck is worth of $27508 after 2 years.
