Answer:

B) 7

Step-by-step explanation:

7 times 7 is 49 and the square root of 49 is 7. Since 49 is the closest to 50 that's means 7 is your answer cuz the others are either smaller than 50 or way bigger than 50.

Does this make sense lol xD I'm terrible at explaining

Can someone help me on this

barxatty [35]

A) as the exponent decreases by one, the number is divided by 5

B) as the exponent decreases by one, the number is divided by 4

C) as the exponent decreases by one, the number is divided by 3

D) 4⁰ = 4 ÷ 4 = 1

4⁻¹ = 1 ÷ 4 = $\frac{1}{4}$

4⁻² = $\frac{1}{4}$ ÷ 4 = $\frac{1}{16}$

E) 3⁰ = 3 ÷ 3 = 1

3⁻¹ = 1 ÷ 3 = $\frac{1}{3}$

3⁻² = $\frac{1}{3}$ ÷ 3 = $\frac{1}{9}$

Use the power-reducing formulas to rewrite the expression as an equivalent expression that does not contain powers of trigonome

ratelena [41]

Answer:

$x = 0.175\cdot (1-\cos 4\cdot \theta)$

Step-by-step explanation:

Let use the following trigonometric identities:

$\sin^{2}\theta = \frac{1-\cos 2\cdot \theta}{2} \\\cos^{2}\theta = \frac{1+\cos 2\cdot \theta}{2}$

Then, the equation is simplified by substituting its components:

$x = 1.40\cdot \left(\frac{1-\cos 2\cdot \theta}{2} \right)\cdot \left(\frac{1+\cos 2\cdot \theta}{2} \right)$

$x = 0.35\cdot (1-\cos^{2}2\cdot \theta)$

$x = 0.35\cdot \sin^{2}2\cdot \theta$

$x = 0.35\cdot \left(\frac{1-\cos 4\cdot \theta}{2} \right)$

$x = 0.175\cdot (1-\cos 4\cdot \theta)$
