Answer:
So the domian of square root of x will be All real numbers greater than or equal to 0.
This can be expressed as:
[0 , ∞)
or
x ≥ 0
Answer:
B
Step-by-step explanation:
Start by writing the ratios equal to each other since they are equivalent.

Notice if you divide 21/3 = 7. Since they are equa then x/3=10. What number divided by 3 equals 10? x=30
Answer:

Step-by-step explanation:
Assuming this is a right triangle.
<u>Trigonometric ratios</u>

where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse
Given:
= 35°- O = x
- A = 26



Therefore, x = 18.21 (nearest hundredth)
Answer:
l3-5 Is how you should write this.
A =7
7^2*3.14*7 sorry I did the equation wrong at first
