Evaluate each expression. Determine if the final simplified form of the expression is positive or negative -42 (-4)2 42

Sati [7]

Answer:

Given the expression:

$-4^2$

we know:

$4^2 = 4 \times 4 = 16$

then;

$-4^2 = -16$

Therefore, the value of expression $-4^2$ is -16 i.e negative.

$(-4)^2$

we know:

$4^2 = 4 \times 4 = 16$

$(-1)^2 = 1$

then;

$(-4)^2 = (-1)^2 \cdot (4)^2= 16$

Therefore, the expression $(-4)^2$ is 16 i.e Positive.

$4^2$

we know:

$4^2 = 4 \times 4 = 16$

then;

$4^2 = 16$

Therefore, the expression $4^2$ is 16 i.e Positive.

What is the measure of ∅? A. 2.5 π radians B. 2.5 radians C. 4 radians D. 5 radians

natka813 [3]

Answer:

C. 4 radians

Step-by-step explanation:

$20=\frac{\pi (Ctrl.Angle)(5)}{180}$

Ctrl Angle = ∅

∅ = $\frac{(20)(180)}{5\pi } =\frac{3600}{5\pi } =\frac{720}{\pi }$

in radians:

∅ = $\frac{720}{180} =4$

Hope this helps
