Answer:
37.7 mi²/h
Step-by-step explanation:
The area formula is ...
A = πr²
Differentiating with respect to time gives ...
dA/dt = 2πr·dr/dt
Filling in the given values, we have ...
dA/dt = 2π(3 mi)(2 mi/h) = 12π mi²/h
The area is increasing at the rate of about 37.7 mi² per hour.
Answer:
9.76m²
Step-by-step explanation:
The area of the square is
where s=8m is the side length.
This means that:
The area of a circle is
From the diagram, the diameter is 8m.
This means that the radius is
The area of the circle then becomes,
The area of shaded region is area of square minus area of circle.
‘a’ is a variable
so this means something multiplied by 1/2 = 11
to solve we will divide both sides by 1/2 to isolate ‘a’
so a= 22
you can verify by plugging 22 into a
so
(1/2)(22)=11
which is true
Answer:
If you can choose 2: A and C
If you can only choose 1: C
where x is never 0
Factoring is the process of simplifying an equation into its original form. For this linear equation:
1. Get this common factor with the two terms. As what we can observe, 3 is the factor of both terms.
2. Thus, to factor the binomial, we write: 3(5x + 2)
