Help. I need both. Please

Darya [45]

Anything to the power of 0 is 1

So for the top, 2^0 = 1
For the bottom, 10^0 = 1

It is not 0, because anything that ends with 0/0 is undetermined, and will not result in an answer

hope this helps

Choices; a) 21.8° b) 35.2° c) 45.1°

kifflom [539]

Answer:

$\displaystyle a) \: {x}^{ \circ} = 21.8 ^{ \circ}$

Step-by-step explanation:

we are given opposite and adjacent

we want to figure out x°

remember that,

$\displaystyle \: \tan( \theta) = \frac{opp}{adj}$

where our opp is 5 and adj is 12.5

let $\theta$ be x°

$\displaystyle \: \tan( {x}^{ \circ} ) = \frac{5}{12.5}$

$\displaystyle \: {x}^{ \circ} = \arctan \left( \frac{5}{12.5} \right)$

by using calculator

$\displaystyle \: {x}^{ \circ} = 21.8$

hence,

our answer is a

Find the distance CD rounded to the nearest tenth

motikmotik

Answer:

CD ≈ 15.0

Step-by-step explanation:

calculate CD using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = C (7, - 4) and (x₂, y₂ ) = D (- 8, - 5)

CD = $\sqrt{(-8-7)^2+(-5-(-4))^2}$

= $\sqrt{-15)^2+(-5+4)^2}$

= $\sqrt{225+(-1)^2}$

= $\sqrt{225+1}$

= $\sqrt{226}$

≈ 15.0 ( to the nearest tenth )
