Answer:
x = 3
Step-by-step explanation:
Parallel lines have equal slopes.
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(- 7, - 5) and (x₂, y₂ ) = B(- 3, x), then
m = ← equate to 2, that is
= 2 ( multiply both sides by 4
x + 5 = 8 ( subtract 5 from both sides )
Given,
Rate of free fall = 216 km/h
Solution,
km/h to m/s is converted as follows :
So, the rate of fall is 60 m/s.
If t = 20 s
Assume, initial velocity = 0
It will move under the action of gravity.
Using equation of motion,
Hence, this is all for the solution.
-2x +8
The terms involving x are "like" terms, so their coefficients are added when the terms are combined.
= 32x -34x +8
= (32 -34)x +8 . . . . . x is factored out according to the distributive property
= -2x +8
C=14pi cm
A=49pi cm^2
1) Circumference of a circle is 2piR and R=7cm
C=2pi(7)
2) Area of a circle is piR^2 and R=7cm
A=pi (7)^2
Answer: 7 feet
