Answer:
Use the square root function on your calculator
Step-by-step explanation:
Look at the third line down, where is says that 936 = AD^2. If you hit the 2nd button on your calculator then the x^2 button, you will get the square root function. After you hit those buttons in that order, you'll get the opportunity to find the square root of 936 by entering it in and hitting "enter" on your calculator. The square root of 936 is 30.59417
Answer:
The best approximation for the measure of angle ABC is:
Third option: 58.3°
Step-by-step explanation:
This is a right triangle, because it has an angle of 90° (right angle) in vertex C, and we need one of the acute angles "x". We have the side opposite to the angle of 90° (right angle), this is the longest side in the right triangle, the Hypotenuse: H=20 cm
We have one of the legs (the sides form the right angle), and this leg is the Adjacent leg: A=10.5 cm to the angle "x".
To find the angle "x" we must use the trigonometric function that relates its adjacent leg (A) with the hypotenuse (H), and this function is cosine:
cos x = Adjacent Leg / Hypotenuse
cos x = A / H
Replacing the known values:
cos x = 10.5 cm / 20 cm
cos x = 0.525
Solving for x:

Rounding to 1 decimal place:
x=58.3°
Answer:
4
Step-by-step explanation:
Evaluate f(3) and g(2)
f(3) = 2(3) - 4 = 6 - 4 = 2
g(2) = - 3(2)² + 5(2) = - 3(4) + 10 = - 12 + 10 = - 2
Then
f(3) - g(2) = 2 - (- 2) = 2 + 2 = 4
Number of soda crates sold by Kent last week = 41
Amount made by Kent for selling each crate = $3.14
Amount made by Kent by selling 41 crates = (3.14 * 41) dollars
= (314/100) * 41 dollars
= 12874/100 dollars
= 128.74 dollars
So the amount of money Kent makes by selling 41 crates of soda bottle is $128.74. this is the easiest way of solving such type of problems. I hope this method will help you to solve these kind of problems in future without requiring any help from others.
