Answer:

y - 9 = 2(x - 1).

Step-by-step explanation:

The slope of the line = (9-3)/(1 -(-2))

= 6/3 = 2

Using the point slope form of the equation of a line:

y - y1 = m(x - x1) where the slope m = 2 and (x1, y1) = (1, 9):

y - 9 = 2(x - 1).

Find the surface are of the cylinder in terms of pi

Andrej [43]

Hello!

To find the surface area of a cylinder you use the equation

$SA = 2 \pi rh + 2 \pi r^{2}$

SA is surface area
r is radius
h is height

PUt in the values you know

$SA = 2 \pi (7)(18) + 2 \pi * 7^{2}$

Square the number

$SA = 2 \pi (7)(18) + 2 \pi * 49$

Multiply 7 and 18

$SA = 2 \pi * 126 + 2 \pi * 49$

Multiply 126 by 2

$SA = 252 \pi + 2 \pi * 49$

Multiply the 49 by 2

$SA = 252 \pi + 98 \pi$

Add

$SA = 350 \pi$

The answer is $A)350 \pi cm^{2}$

Hope this helps!

Four years after opening an account that paid simple interest of 4.25% annually, a depositor withdrew the $2,380 in interest ear

satela [25.4K]

Answer:

Step-by-step explanation:

In order to figure out how much money was left in the account after the interest was withdrawn, we have to first find out how much money was initially deposited to earn that amount of interest! The means to find that initial investment is found in the simple interest formula

prt = I, where

p is the initial investement,

r is the interest rate in decimal form,

t is the time in years, and

I is the interest earned. Notice that we have all those things but the p.

Filling in:

p(.0425)(4) = 2380 and

.17p = 2380 so

p = 14000

That means that 14000 was initially invested. If the depositor withdrew the 2380, then

14000 - 2380 is the amount left in the account, namely, $11620

Simplify \frac{5}{3}x35x to \frac{5x}{3}35x

x-\frac{5x}{3}<3x−35x<3

2

Simplify x-\frac{5x}{3}x−35x to -\frac{2x}{3}−32x

-\frac{2x}{3}<3−32x<3

3

Multiply both sides by 33

-2x<3\times 3−2x<3×3

4

Simplify 3\times 33×3 to 99

-2x<9−2x<9

5

Divide both sides by -2−2

x>-\frac{9}{2}x>−29
