So it's B, since you have both variables of x and y. And you can get y alone, to get a constant for x, which is what makes it linear. It can't be A since the x is squared, and on a graph it's a curved shape (parabola) so it is nonlinear

The Darnells are having a swimming pool installed. The pool has a radius of 14 feet and a height of 4 feet. What is the volume o

ella [17]

So a circular pool will be in the shape of a cylinder. and the formula for finding the area of a cylinder is $2 \pi r^{2} +2 \pi rh$ . r=radius, h=height. If we put the numbers into the equation it is $2 \pi 14^{2} +2 \pi 14(4).$ .14 squared is 196 and 4*14= 56. So our equation is now $2 \pi (196)+2 \pi (56)$ . 2*pi=6.28318530718 but let's round that to 6.283. So now our equation is much simpler 6.283(196)+6.283(56). Just multiply them. 1231.504+351.858= <span>1583.362</span> is your final answer.

Mark recorded the growth of a plant over 8 weeks. The equation y=0.2 x+2

Leto [7]

Answer:

A. The height of the plant after week 3 was about 2.6 inches.

C. The height of the plant after week 9 was about 3.8 inches.

Step-by-step explanation:

The equation given:

Y = 0.2x + 2

x represents the number of weeks

substituting x = 3 into the equation , we will have

y = 0.2(3) + 2

y = 0.6 + 2

y = 2.6

This means that the height of the plant after week 3 was about 2.6 inches.

Also , substituting x = 9 into the equation will give

y = 0.2 (9) + 2

y = 1.8 + 2

y = 3.8

This means that the height of the plant after week 9 was about 3.8 inches.

When rolling a die, what is the probability of rolling a 1 or a 4 write your answer in a fraction?

Andrej [43]

Answer:

$1/3$

Step-by-step explanation:

There are 6 values on a die, and we want 2 values. The fraction now is $2/6$ . But, wait! We can simplify this fraction: $1/3$ .

Side note:

I understand if you wanted just the $2/6$ fraction and not simplified.

Is (0,0) a solution to this system? y ≥ x^2 + x - 4, y> x^2 + 2x + 1

Ipatiy [6.2K]

Y≥x²+x-4
y>x²+2x+1

Substitute (0,0):

0≥-4 true
0>1 false

(0,0) is not a solution of the system.
