Answer: 308cm

Step-by-step explanation: The formula to find the curved surface area of a cylinder is 2πr × h. The formula for curcufrence is 2πr.

So,

2πr (circumfrence)= 44cm.

Height= 7cm.

2πr × h = 44 x 7 = Curved surface area.

Curved surface area= 308cm

6z + 7  = 8z - 9

8z - 9 = 6z + 7

Add sides 9

8z - 9 + 9 = 6z + 7 + 9

8z = 6z + 16

Subtract sides 6z

- 6z + 8z =  - 6z + 6z + 16

2z = 16

Divide sides by 2

\frac{2z}{2}  =  \frac{16}{2}  \\

z = 8

Thus ;

NP = 8z - 9

NP = 8(8) - 9

NP = 64 - 9

NP = 64 - 4 - 5

NP = 60 - 5

NP = 55

Done...

What is the slope of the line passing through the points (-1,-7) and (-9,-2)?
nalin [4]

Answer: m = -5/8

Step-by-step explanation:

The general equation for slope is rise over run, also known as:

m=(y2-y1)/(x2-x1)

From the points (x, y), we can get all the variables we need.

(-1, -7) gives us x1 = -1 and y1 = -7

(-9, -2) gives us x2 = -9 and y2 = -2

If we plug all the values in, we get:

m = (-2 - (-7))/(-9 - (-1))

m = (-2 + 7)/(-9 + 1) the negatives cancel

m = (5)/(-8)

m = -5/8

Vesnalui [34]
It is just the multiplication of vectors. We'll multiply corresponding pairs together. The general formula for the pairs of (x_{1}; y_{1}) and (x_{2}; y_{2}) is x_{1} * x_{2} + y_{1} *  y_{2} = (-6)*(-3)+4*6=18+24=42

Find the solution of this system of equations.
Elenna [48]
<span>-4x + y = -25        y = 4x - 25

-6x - 6y = 0            </span>
 
-6x - 6(4x - 25) = 0
-6x - 24x + 150 = 0
-30x + 150 = 0
-30x = -150
x = 5

y = 4(5) - 25
y = 20 - 25
y = -5

(5, -5)
