Answer: She needed 144 square feet of carpet.
Step-by-step explanation:
Given : Maria is buying new carpet. Her bedroom is in the shape of a square.
The length of each side is 12 feet.
We know that the area of square =
So , the area of the bedroom = [which is an exponential expression]
Simplify it
The area of the bedroom =
Also, the carpet she needed = Area of the bedroom.
Thus , She needed 144 square feet of carpet.
Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - , then
y = - x + c ← is the partial equation
To find c substitute (6, - 1 ) into the partial equation
- 1 = - 2 + c ⇒ c = - 1 + 2 = 1
y = - x + 1 ← equation of line
Answer:
Step-by-step explanation:
The swing of the tip of pendulum is creating an arc. The question is actually asking for the length of this arc. The length of an arc is given by , where
is the radius of the circle and
is the angle of the arc.
In this problem, we're given:
Substituting given values, we get:
