Answer:

A. 32°

Step-by-step explanation:

$\tan \: x \degree = \frac{40}{64} \\ \\ \tan \: x \degree = \frac{5}{8} \\ \\ \tan \: x \degree =0.625 \\ x \degree = {\tan}^{ - 1}( 0.625) \\ \\ x \degree =32.005383208 \degree \\ \\ \huge \red { \boxed{ x =32 \degree}}$

Find the distance between the points (4,3) and (2,-1). Express your answer in simplest radical form.

Kamila [148]

Answer : B

the distance between the points (4,3) and (2,-1)

We apply distance formula

$d^2= (x_2-x1)^2 + (y_2-y_1)^2$

(x1,y1) is (4,3)

(x2,y2) is (2,1)

$d^2= (2-4)^2 + (-1-3)^2$

$d^2= (-2)^2 + (-4)^2$

d^2 = 4+16 = 20

Take square root on both sides

So $d=2\sqrt{5}$

the distance between the points (4,3) and (2,-1) is 2sqrt(5)

If (-3)^-5=1/x what is the value of x Answers: -243 -1/243 1/243 243

Inga [223]

Solve -3^-5.

Knowing that $x^{-1} = \frac{1}{x}$ , then $-3^{-5}= \frac{-1}{243}$

That means that x = -243.
