Answer:

160,000 sq ft

Step-by-step explanation:

2018 is 13 years after 2005.

Put x=13 in the equation and evaluate:

... y = 0.538·13 +9.02 = 6.994 +9.02 = 16.014

This is the number of 10,000 sq ft, so the required area is ...

... 16 times 10,000 sq ft = 160,000 sq ft.

Solve the following system of equations graphically on the set of axes below.

professor190 [17]

The solution of the given equations is: (-1.5, 1.5)

Step-by-step explanation:

Linear equation usually represents a straight line. When a system of two liner equations is given, the point of intersection of lines represented by both equations is the solution of the system of equations.

We will plot the lines of both equations and find their point of intersection (Picture Attached)

We can see in the picture that two lines intersect at (-1.5, 1.5)

Hence,

The solution of the given equations is: (-1.5, 1.5)

The volume of a cone with a height of 4 cm is 12π cubic cm. What is the radius of the base?

blondinia [14]

Answer:

r = 6cm

Step-by-step explanation:

Solve for r:

$v = \frac{1}{3} \pi {r}^{2}$

$12\pi = \frac{1}{3} \pi {r}^{2} \\ 12\pi = \frac{\pi {r}^{2} }{3} \\ 3 \times 12\pi = \pi {r}^{2} \\ 36\pi = \pi {r}^{2} \\ \frac{36\pi}{\pi} = \frac{\pi {r}^{2} }{\pi} \\ \sqrt{ {r}^{2} } = \sqrt{36} \\ r = 6$
