The first one is A. Number 2 is d. Number 3 is b because 20x20=400 and 21x21=441 and when you add them together you get 841 or 29x29. Number 4 is b because complementary angles are also right angles, they have to add up to 90 degrees. Number 5 is a because every angle is less than 90 degree. Number 6 is 30 because 60+90+x = 180 and when you solve for x you will get 30 degrees.
Answer:
A
Step-by-step explanation:
The projectile motion of Jenny's dive can be represented by 
where a is acceleration, v_0 is velocity, t is time, and h_0 is initial height.
Jenny's vertical height above the water is represented by 
. 10 is h_0 and is Jenny's initial height.
Answer:
Area = 22.3 m^2
Perimeter 27.4 m^2
Step-by-step explanation:
Perimeter = __ m
Area __ m^2
The area of the triangle is about 4.2,
The area of the square is 4,
The area of the semicircle is 14.1,
14.1 + 4.2 + 4 = 22.3
Area = 22.3 m^2
9.4 + 6 + 4 + 4 + 4 = 27.4
Perimeter = 27.4 m^2
Therefore the area of the shape is about 22.3 m^2 and the perimeter is about 27.4 m^2.
