Answer:

A. y=10x+50

Step-by-step explanation:

you only add $50 once because it is the "become a member fee", you put a X next to the 10 because its monthly. (so you can replace the variable with any number if needed)

The radius of a right circular cone is increasing at a rate of 1.5 in/s while its height is decreasing at a rate of 2.1 in/s. At

givi [52]

Answer:

The volume of the cone is changing at a rate of approximately 8670.796 cubic inches per second.

Step-by-step explanation:

Geometrically speaking, the volume of the right circular cone ( $V$ ), in cubic inches, is defined by the following formula:

$V = \frac{1}{3}\cdot \pi \cdot r^{2}\cdot h$ (1)

Where:

$r$ - Radius, in inches.

$h$ - Height, in inches.

Then, we derive an expression for the rate of change of the volume ( $\dot V$ ), in cubic inches per second, by derivatives:

$\dot V = \frac{1}{3}\cdot \pi \cdot (2\cdot r\cdot h \cdot \dot r + r^{2}\cdot \dot h)$ (2)

Where:

$\dot r$ - Rate of change of the radius, in inches per second.

$\dot h$ - Rate of change of the height, in inches per second.

If we know that $r = 120\,in$ , $\dot r = 1.5\,\frac{in}{s}$ , $h = 107\,in$ and $\dot h = -2.1\,\frac{in}{s}$ , then the rate of change of the volume is:

$\dot V \approx 8670.796\,\frac{in^{3}}{s}$

The volume of the cone is changing at a rate of approximately 8670.796 cubic inches per second.

What is the midpoint (-4,0) and (10,7)?

mestny [16]

We first use midpoint formula
X1+X2 divided by 2 we want x for midpoint.
Y1+Y2 divided by 2 we want Y for midpoint
10-4 divided by 2 =3
7-0 divided by 2 =7/2
therefore midpoint= (3;7/2)

Is 120 of 100 larger than 100

iragen [17]

$\text{Hey there!}$

$\text{Is 120\% of 100 larger than 100?}$

$\boxed{\text{The answer is: YES it is larger than 100}}\checkmark$

$\text{Reason}\downarrow\\\text{The word "of" means multiply in mathematical terms}\\\text{120\% = 1.2}\\\text{Re-ask yourself: Is 1.2}\times\text{100 larger than 100?}\\\bf{1.2\times100 = 120}\\\text{120 is LARGER/BIGGER than 100}$

$\text{Good luck on your assignment and enjoy your day!}$
