<u>Given</u>:
The graph shows the speed of a ball in free fall for 10 seconds.
We need to determine the constant of proportionality for the given graph.
<u>Constant of proportionality:</u>
The constant of proportionality can be determined using the formula,
Where k is the constant of proportionality.
Let us consider any of the coordinate from the graph and substitute in the formula.
Consider the coordinate (4,40) and substitute in the above formula.
Thus, we have;
Thus, the constant of proportionality is 10 meters per second squared.
Answer:
Step-by-step explanation:
in complementary angle, the sum of two angle is always 90 degree.
let another angle be x
x+78.7=90
x=90-78.7
x=11.3
therefore anothere angle is 11.3 degree.
Answer:
x = 16
Step-by-step explanation:
m<B+m<C+m<D = 180°
5x + 14 + x + 19 + 2x + 19 = 180
8x + 52 = 180
8x = 180 - 52
x = 128/8
x = 16
Answer is c
a and d are crossed off because the action of going up and down is adding and subtracting. Absolute values of any number is a positive. So b and c are left. Then b is crossed out because the is subtracting each value from another which affects the result. Negatives change signs. Positives don't. So you want an equation that sums up all individual values without affect the signs. Answer is C.
Answer:
480 m²
Step-by-step explanation:
A = bh/2
A = 64 m × 15 m / 2
A = 480 m²
