Answer: FALSE, FALSE, FALSE (there is a bar under the > sign which means it can be equal), TRUE, FALSE (if 34 is the solution then it equals x, and that number would be multiplied by five and added to one, which is well over 35)

If angle YWZ = 17, what is angle WXY?
marusya05 [52]
We know that

step 1
if ∡YWZ=17°
then
∡XWZ=17°*2-----> 34°----> because triangle XWY and triangle YWZ are congruents

step 2
∡WXY=∡WZY-------> because triangle XWY and triangle YWZ are congruents
we know that 
<span>the sum of the internal angles of a triangle is 180 degrees
</span>so
180°=∡XWZ+2*∡WXY---------> ∡WXY=[180-∡XWZ]/2
∡WXY=[180-34°]/2-------> ∡WXY=73°

the answer is
∡WXY=73°

The function LaTeX: f\left(x\right)=-x^2+4f ( x ) = − x 2 + 4 defined on the interval LaTeX: -8\le x\le8− 8 ≤ x ≤ 8 is increasin
enyata [817]

Given:

The function is

f(x)=-x^2+4

It defined on the interval -8 ≤ x ≤ 8.

To find:

The intervals on which the function is increasing and the interval on which decreasing.

Step-by-step explanation:

We have,

f(x)=-x^2+4

Differentiate with respect to x.

f'(x)=-(2x)+(0)

f'(x)=-2x

For turning point f'(x)=0.

-2x=0

x=0

Now, 0 divides the interval -8 ≤ x ≤ 8 in two parts [-8,0] and [0,8]

For interval [-8,0], f'(x)>0, it means increasing.

For interval [0,8], f'(x)<0, it means decreasing.

Therefore, the function is increasing on the interval [-8,0] and decreasing on the interval [0,8].
