Answer:

4 * 14 = 56

Step-by-step explanation:

56/2 = 28

28/2 = 14

14/2 = 7

7/7 = 1

56 = 2 * 2 * 2 * 7

56 = (2 * 2) * (2 * 7)

56 = 4 * 14

Answer:

a. x = 3

b. x = 3

Step-by-step explanation:

Given

$\frac{4^{2x}}{4^x} = 64$

$(2^{2x}) = 64$

Required

Find x

Solving $\frac{4^{2x}}{4^x} = 64$

From laws of indices;

$\frac{a^{m}}{a^n} = a^{m-n}$

So;

$4^{2x-x} = 64$

$4^{x} = 64$

Write 64 in base of 4

$4^{x} = 4^3$

From laws of indices;

$if\ x^a = x^b;\ then\ a = b$

So; x = 3

Solving $(2^{2x}) = 64$

Write 64 as a base of 2

$(2^{2x}) = 2^6$

$if\ x^a = x^b;\ then\ a = b$

$2x = 6$

Divide both sides by 2

$\frac{2x}{2} = \frac{6}{2}$

$x = 3$

If r=20.5 and s=34.2 find S Round to the nearest tenth

astraxan [27]

Answer: option d

Step-by-step explanation:

Remember the identity:

$tan\alpha=\frac{opposite}{adjacent}$

The inverse of the tangent function is arctangent. You need to use this to calculate the angle "S":

$\alpha =arctan(\frac{opposite}{adjacent})$

Knowing that: you need to find the measure of the angle "S" , $r=20.5$ (which is the adjacent side) and $s=34.2$ (which is the opposite side), you can sustitute values into $\alpha =arctan(\frac{opposite}{adjacent})$

Then, you get that the measure of "S" rounded to the nearest tenth is:

$S=arctan(\frac{34.2}{20.5})\\\\S=59.1\°$
