Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Write an exponential function =for a graph that passes through (2,1) and (3,10). Ill give you whatever please help

GrogVix [38]

Answer:

$y = \frac{1}{100} \times 10{}^{x}$

Step-by-step explanation:

Use coordinates (2,1) and 3,10

The exponential equation is

$y = a \times b {}^{x}$

Plug in the x and y values.xfor both functions of coordinates.

$1 = a \times b {}^{2}$

$10 = a \times b {}^{3}$

Divide the equation with the larger exponet by the other equation.

$10 = b$

Substitute that in for one of the equations.

$10 = a \times 10 {}^{3}$

Solve for a.

$10 = a \times 1000$

$\frac{1}{100} = a$

So our exponetial equation is

$y = \frac{1}{100} \times 10 {}^{x}$

A can in the shape of a right cylinder is filled with 10W-40 oil. The weight of 10W-40 oil is 0.857 gram per cubic centimeter. I

disa [49]

First find the area of the cylinder using the following formula
$A = 2\pi rh + 2\pi r^2$
$A = (2 \times \pi \times 6 \times 10) + (2 \times \pi \times 6^2)$

After finding the area, calculate the weight of the oil (in grams) in the can

weight in grams = A times 0.857
