Very confusing wording and your picture is blurry sorry
Estimate 95 to 90 and 8 to 10
now multiply 90 and 10 = 900
Answer:
It depends on the value of x
Step-by-step explanation:
If x=1, then yes
Exponents come before multiplication, so even if 2*4=8, 2*4^2 is not equal to 8.
Ex:
2*4^2=32
8^2=64
Answer:
B and C
Step-by-step explanation:
We can just solve each to find which expressions are equal to 1.5.
A) 0.15 × 100 = 15
B) 15.0 ÷ 10 = 1.5
C) 0.15 × 10 = 1.5
D) 0.15 ÷ 10 = 0.015
E) 1.5 ÷ 100 = 0.015
From our results, we see that B and C are the only answers that equal 1.5.
Answer:
90°, 270°
Step-by-step explanation:
2r sin(Ф/2) = c
2r sin (Ф/2) = √2r
divide both sides by 2r
sin (Ф/2) = √2r/2r
sin(Ф/2) = √2/2
From the unit circle sin is √2/2 at 45°, and 135°
so Ф/2 = 45
Ф=90°
and Ф/2 = 135
Ф= 270°
