I can’t help don’t have any question and photo
Answer:
Step-by-step explanation:
This means that <C and <F are congruent.
So 2x - 15 = x + 15 Add 15 to both sides
2x-15+15=x+15+ 15
2x = x + 30 Subtract x from both sides
2x-x=x-x+30
x = 30
I've taken the bottom 2 angles to be equal. The lettering says they
are
I’m trying to find this too
Answer:
3.8 meters
Step-by-step explanation:
In order to find the circumference for a circle, we use the formula π(radius)²
The circumference give is 45.84 and the π given is 3.14
All we have to do is to just substitute them.
45.84 = 3.14(radius)²
45.84 / 3.14 = radius²
14.6 = radius²
radius = √14.6
radius = 3.82 ≅ 3.8
The veretx is normally the minimum value
hack:
for f(x)=ax²+bx+c
the x value of the vertex is -b/2a
so
f(x)=1x²-16x+71
x value is -(-16)/(2*1)=16/2=8
find f(8) to find y value of vertex
f(8)=8²-16(8)+71
f(8)=64-128+71
f(8)=7
the vertex is (8,7)
the minimum value is 7
