Answer:
4
Step-by-step explanation:
f(x) = 3x - 1, g(x) = 2x - 3
f(2) = 3(2) - 1 = 6 - 1 = 5.
If g(x) = f(2).
2x - 3 = 5
2x = 8
x = 4. This value ensures g(x) = f(2).
A. is not a real number, or square root -3
Negative numbers do NOT have a square root because it is negative
Answer:
the volume of the sphere is 507.78981 cm^3
Step-by-step explanation:
The computation of the volume of the sphere is given below:
Given that
The Diameter is 9.9 cm
So, the volume of the sphere is
= 4 ÷ 3 ×π × r^3
= 4 ÷ 3 × 3.14 × 9.9 ÷ 2^3
= 4 ÷ 3 × 3.14 × 4.95^3
= 507.78981 cm^3
Here r denotes the radius
And, the radius would be comes by dividing the diameter from 2
Hence, the volume of the sphere is 507.78981 cm^3
Answer:
D. 50 students
Step-by-step explanation:
First we find the area of the classroom which is worked out below and it is the shape of a rectangle;
Area of a rectangle = Length * Breadth
= 60 ft * 40 ft
= 2400 ft²
Now to find the number of students that she will allow in the classroom, we have to divide the area of the classroom which is 2400 ft²by the amount of space allocated to each student which will be;
=
= 50
This means she will allow 50 students into her class.
