Negative 10.9p plus 3.9 equals negative 9.18.... what does p equal

Julli [10]

Answer:

-1.2

Step-by-step explanation:

$10.9p+3.9=-9.18$

Subtract 3.9 from -9.18 to isolate the variable.

$10.9p=-13.08$

Divide -13.08 by 10.9

$-13.08/10.9=-1.2$

Which equals

$p=-1.2$

10. The surface area of a cylinder with radius rand height h is twice the product of r and the

rusak2 [61]

Step-by-step explanation:

The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :

$A=2\pi rh$

$A=2\pi \times r\times h$

We also know that, surface area = perimeter×height

So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.

Find the slope of the line through the pair of points.

erastovalidia [21]

Answer:

The answer is A undefined

Step-by-step explanation:

The slope is given by

$m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$m=\frac{9-(-13)}{17-17}=\frac{22}{0}$

which is undefined (division by zero)

PLEASE help me with this question! This is really urgent! No nonsense answers please.

Answer:

The second table of values.

Step-by-step explanation:

Let's put the x-values in the second table of values in correct number order:

x: -3, -2, -1, 0, 1

Now, let's write out the y-values in correct number order:

y: 1/4, 1, 4, 16, 64

Finally, let's rewrite the second table of values with the x-values in order and the corresponding y-values underneathe:

x: -3, -2, -1 0 1

y: 64, 16, 4, 1, 1/4

As it can be seen, as the x-values get bigger in value, the y-values get smaller exponentially, which is the definition of exponential decay.
