Answer:

0 < f(x) ≤ 3/4, or (0, 3/4]

Step-by-step explanation:

x² - x + 1 = x² - x + 1/4 + 3/4 = (x - 1/2)² + 3/4

It is always positive and has a minimum value of 3/4 at x = 1/2

So f(x) is always positive (not equal zero) and has a maximum value of 3/4

Then the range is 0 < f(x) ≤ 3/4, or (0, 3/4]

A garden store bought a fountain at a cost of $995.66 and marked it up 100%. Later on, the store marked it down 25%. What was the discount price?

Answers

Answer:

248.91500

Step-by-step explanation:

Answer: $1493.49

Step-by-step explanation:

Mark-up formulas:

price=cost+mark-up

mark-up=mark-up percentage×cost

Discount formulas:

discount price=original price–discount

discount=discount percentage×original price

solve

First find the original price. Write 100% as the decimal 1.00 before using it in the equation.

price

= cost+mark-up

= 995.66+1.00×995.66

= 995.66+995.66

= 1,991.32

The original price was $1,991.32.

Now find the discount price. Write 25% as the decimal 0.25 before using it in the equation.

discount price

= original price–discount

= 1,991.32–0.25×1,991.32

= 1,991.32–497.83

= 1,493.49

The discount price was $1,493.49.

First consider the volume of the given figure
Volume =length x width x height
V=L x W x H
B=2 1/2=2.5 cm , L=2 cm , H=1 cm
V= 2.5 x 2 x 1 =5 cm3

Considering the volume of the given cube
L=H=W
For a cube the sides are the same
V = L x W x H L = 1/2 = 0.5
V= (L)3
V=(0.5)3
V=0.125 cm3

Hence number of cubes
= volume of cube / volume of fig
= 0.125/5

Answers

The volume of the prism that is completely filled with 72 cubes that have edge lengths of 1/2 in. is 9 in³.

What is a prism?

A prism is a 3-dimensional shape, with two identical shapes facing each other.

To calculate the volume of the prism, we use the formula below.

Formula:

The volume of the prism (V) = 72×volume of one cubeV = 72L³............. Equation 1

Where:

V = Volume of the prismL = Length of the cube

From the question,

Given:

L = 1/2 in

Substitute these values into equation 1

V = 72(1/2)³V = 72(1/8)V = 9 in³

Hence, the volume of the prism is 9 in³.

There are t boys in class. There are 7 fewer girls in class. How many students are in class in terms of t?

Answers

Answer:

[tex]2t-7[/tex]

Step-by-step explanation:

Let "t" represent the boys in the class then the amount of girls will be:

[tex]t-7[/tex]

Total Students = Number of Boys + Number of Girls

Total Students = [tex]t+t-7[/tex]

Total Students = [tex]2t-7[/tex]

Let's use a few example numbers to see if this equation is true...

[tex]t=10[/tex]

[tex]t-7=10-7=3[/tex]

[tex]10+3=13[/tex]

This means that [tex]2t-7[/tex] must also be equivalent to 13...

[tex]2(10)-7=20-7=13\rightarrow $ Correct![/tex]

Another example...

[tex]t=15[/tex]

[tex]t-7=15-7=8[/tex]

[tex]15+8=23[/tex]

This means that [tex]2t-7[/tex] must also be equivalent to 23...

Write an equation that states (x, y) is the same distance from (4, 1) as it is from the x-axis.

Answers

The equation that gives all the points (x, y) that are at the same distance from (4, 1) as from the x-axis is:

y = (1/2)*(x - 4)^2 + 1/2.

How we can find the point (x, y)?

First, remember that for a point (x, y), the distance to the x-axis is equal to y.

And we also know that the distance between two points (x₁, y₁) and (x₂, y₂) is:

[tex]d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex]

The distance between (x, y) and (4, 1) is:

[tex]d = \sqrt{(x - 4)^2 + (y - 1)^2}[/tex]

And this must be equal to y, so we can write:

[tex]y = \sqrt{(x - 4)^2 + (y - 1)^2}[/tex]

This is the equation we need to solve.

We will get:

[tex]y^2 = (x - 4)^2 + (y - 1)^2\\\\y^2 = (x - 4)^2 + y^2 - 2y + 1\\\\0 = (x - 4)^2 - 2y + 1\\\\2y = (x - 4)^2 + 1\\\\y = (1/2)*(x - 4)^2 + 1/2[/tex]

This equation gives all the points (x, y) that are at the same distance of (4, 1) as from the x-axis.
