The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have:

$(-3,\ 9)\to x_1=-3,\ y_1=9\\(-3,\ -5)\to x_2=-3,\ y_2=9$

Substitute:

$m=\dfrac{-5-9}{-3-(-3)}=\dfrac{-14}{-3+3}=\dfrac{-14}{0}\ \ \ \boxed{!!!!!}$

Answer: The slope is indefinite

Hi there! :)

Step-by-step explanation:

$SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{(-5)-9}{(-3)-(-3)}=\frac{-5-9}{-3+3}=\frac{-14}{0}=0$

Undefined.

Slope is 0.

Final answer is 0.

Hope this helps!

What is the value of the missing exponent? 123,456,789 = 1.23456789 x 10^

mestny [16]

Answer:

$123,456,789 = 1.23456789\times 10^8$

Step-by-step explanation:

It is required to find the value of the missing exponent in the below value i.e.

$123,456,789 = 1.23456789\times 10^x$

Let the exponent is x.

Any number can be written in the scientific notation as :

$N=a\times 10^b$

a is a real number

b is any integer

In this case, the decimal is applied before 8 numbers. It means that the value of x is 8.

A cylinder has a diameter of 6 feet. the volume of the cylinder is 36/5π cubic feet.

Anton [14]

Answer:

Height of cylinder is $\frac{4}{5}\ ft$ .

Step-by-step explanation:

Diameter of cylinder, D = 6 feet

Relation between Radius, R and diameter, D is given by:

$R = \dfrac{D}{2}$

So, radius, R = $\frac{6}{2} \Rightarrow 3$ feet

Let height of cylinder be $h$ feet.

Formula for volume of cylinder is given by:

$V = \pi R^{2} H$

Where, R is the radius of base of cylinder

and H is the height of cylinder

We are given that,

$V = \dfrac{36 \pi}{5} ft^{3}$

Using formula for volume, $V = \pi R^{2} H$

$\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft$

Hence, Height of cylinder is $\frac{4}{5}\ ft$ .

By how much is the product of 9/5 and 8 1/4 greater than 5

Oliga [24]

Given:

The product of $\dfrac{9}{5}$ and $8\dfrac{1}{4}$ greater than 5.

To find:

By how much the product of $\dfrac{9}{5}$ and $8\dfrac{1}{4}$ greater than 5.

Solution:

First we need to find the product of $\dfrac{9}{5}$ and $8\dfrac{1}{4}$ .

$\text{Product}=\dfrac{9}{5}\times 8\dfrac{1}{4}$

$\text{Product}=\dfrac{9}{5}\times \dfrac{8(4)+1}{4}$

$\text{Product}=\dfrac{9}{5}\times \dfrac{33}{4}$

$\text{Product}=14.85$

Now subtract 5 from the product.

$14.85-5=9.85$

Therefore, the product of $\dfrac{9}{5}$ and $8\dfrac{1}{4}$ is 9.85 greater than 5.
