First question:

When you bisect an angle, you create two new equal angles, both measuring half of the original angle. So, if the original angle was 52°, the two angles will be 52/2=26 degrees each.

Note: the picture is not very clear, and I'm not sure the original angle is 52°. It it's not, just divide by 2 whatever measure the angle is.

Second question:

Focus on triangles RQP and RSP:

They are both right, because Q and S are right angles
We are given QP=SP
They share the side RP

So, they are congruent. This implies that angle SRP is 50° as well, and then

QRS = QRP+SRP = 50°+50°=100°

Assuming you're working in base 10, then the antilog of 3.493 is equal to 10^3.493 = 3,111.71633710601

This rounds to 3111.7163 so the answer is choice D

Which functions have a vertex with a x-value of O? Select three options.

hram777 [196]

Answer:

Below.

Step-by-step explanation:

f(x) = |x| This is shaped like a V with the vertex at (0,0).

f(x) = |x| + 3 this is also shaped live a V with the vertex at (0, 3).

(This is |x| translated up 3 units).

f(x) = |x| - 6 similar to the above with the vertex at (0, -6).

(This is |x| translated down 6 units).
