guajiro [1.7K]

Answer:

5 - x

Step-by-step explanation:

Given:

$f(x)=25-x^2$

$g(x)=x+5$

$\begin{aligned}\left(\dfrac{f}{g}\right)(x) & = \dfrac{f(x)}{g(x)}\\\\ & = \dfrac{25-x^2}{x+5}\\\\& = \dfrac{(5-x)(5+x)}{(x+5)}\\\\& = \dfrac{(5-x)(x+5)}{(x+5)}\\\\& = 5-x\end{aligned}$

What is the area of this face? A.150in2 B.100in2 C.400in2 D.200in2

Levart [38]

Answer:

200 in squared.

Step-by-step explanation:

The top face has a height of 10, it also has a side length of 10. 5 plus 5 equals 10. These faces are squares, so the sides are equal. In this case, they 10 by 10. To find the of the face you do 10 times 10 times 2 because there are 2 figures, or you can find the area of one (100) and the area of the other (100) and add the areas up to get the area of the face. Hope this helps!

Find the measures of angels of M and N M (6y-10) N (4y-10)

PSYCHO15rus [73]

We have been given an image of a trapezoid. We are asked to find the measure of angle M and N.

We know that bases of trapezoid are parallel and the two angles between two parallel lines are supplementary, so we can set an equation as:

$\angle M+\angle N=180$

$(6y-10)+(4y-10)=180$

$6y-10+4y-10=180$

$10y-20=180$

$10y-20+20=180+20$

$10y=200$

$\frac{10y}{10}=\frac{200}{10}$

$y=20$

Upon substituting value of y in measure of angle M, we will get:

$m\angle M=6y-10$

$m\angle M=6(20)-10$

$m\angle M=120-10$

$m\angle M=110$

Therefore, measure of angle M is 110 degrees.

Similarly, we will find the value of angle N as:

$m\angle N=4y-10$

$m\angle N=4(20)-10$

$m\angle N=80-10$

$m\angle N=70$

Therefore, measure of angle N is 70 degrees.

What is the general form of the equation for the given circle centered at O(0, 0)?

eduard

The general form of such an equation is
x^2 + y^2 = r^2 where r = radius

In this case r^2 = 4^2 + 5^2 = 41

So the required equation is x^2 ^ y^2 = 41
