Answer:
50⁰
Step-by-step explanation:
the 2 triangles are congruent, meaning the angles equal the same. angles B and S are the same, angles A and R are the same, and angles Q and C are the same (congruent)
Answer:
Vertex is (-4, -18)
Step-by-step explanation:
f(x) = 
Let (h, k) be the vertex
An easy way to find h is to use the formula h = -b/2a
In your case where f(x) = 
a = 2 and b = 8
So, h = -8/2(1) = -8/2 = -4
Substitue -4 in for x to find k
k = (
) + 8(-4) - 2
= (16) - 32 - 2
= 16 - 32 - 2
= -18
Vertex is (-4, -18)
Note: Another way to find the vertex is to complete the square, but this can really be difficult in some cases
Answer: d, eight and fifty-three thousandths
Step-by-step explanation:
The number before the decimal place in the units column is a whole number (8).
The numbers after (.053) are thousandths because the whole number (8.053) consists of 4 numbers the same way a 1000 does.
Sorry I found the last bit harder to put into words, but I hope it helps :)
