Answer:

We have

5000 + ( 10 / 100 ) x 5000 = 5000 + ( 1 / 10 ) x 5000 = 5000 + 500 = 5500 people visit the book fair in the second week.

Your answer would be x = -15.8994.

To get this, you first add 7 to each side making the equation -4.818 = x/3.3

Then, you would need to multiply each side by 3.3 to get x by itself.

Your answer would be -15.8994.

Ella has ½ gallon of orange juice left that must last 4 days. How much can she drink each day?

Masja [62]

She can drink 1/8 each day.

This is because we do 1/2 divided by 4 which would equally distribute the amount she can drink each day.

A cylinder vase has a height of 10 inches and a diameter of 3 inches. If the water raises to 9/10 of the way to the top, approxi

goblinko [34]

Answer:

The volume of water in the vase is $64 in^3$

Step-by-step explanation:

A cylinder vase has a height, h, of 10 inches and its diameter of 3 inches. This means that its radius, r, is:

r = 3 / 2 = 1.5 inches

To find the volume of the water in the vase if the water raises to 9/10 of the way to the top, we first have to find the volume of the vase when it is filled with water and then, find 9/10 of that volume.

The volume of a cylinder is given as:

$V = \pi r^2h$

The volume of the vase will be:

$V = \pi * 1.5^2 * 10\\V = 70.69 in^3$

Hence, the volume of the water in the vase when it is 9/10 filled is:

$\frac{9}{10} * 70.69 = 63.62 in^3$

Approximating to the nearest cubic inch, the volume of water in the vase is $64 in^3$

What are the roots of the polynomial equation x^4+x^3=4x^2+4x? Use a graphing calculator and a system of equations.

Yuliya22 [10]

Desmos graphing calculator will draw this graph for you.

draw 2 curves

y = x^4 + x^3
and
y = 4x^2 + 4x

The roots are the points where the 2 curves intersect.

You can see by simple substitution that one root is zero.

x^4 + x^3 - 4x^2 - 4x = 0

f(2) = 16 + 8 - 4(4) - 4(2) = 0 so 2 is another root

f(-2) = 16 - 8 - 16 + 8 = 0 so -2 is another root

f(-1) = 1 - 1 - 4 + 4 = 0 so -1 is the other root

The answer is A
