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]

Answer:

A.

Step-by-step explanation:

the ratio of shaded is 8:12 simplified to 3:4

the ration of shaded but with a cross is 7: 12. simplified it least value.

the ration of shaded with a cross and just shaded is 8:12 to 7:12, subtract those and you get 1:12

sooo you're answer is 8:12 - 1:12 to see the shaded with cross

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.

Answer:

9.6

Step-by-step explanation:

As YZ is parallel to VX, then ΔWYZ ≅ ΔWVX

⇒ WX : WV = WZ : ZX

⇒ 5.6 : (5.6 + 8.4) : 6.4 : (6.4 + J)

[tex]\implies \dfrac{5.6}{5.6+8.4}=\dfrac{6.4}{6.4+J}x^{2}[/tex]

[tex]\implies 5.6(6.4 + J)=6.4 (5.6+8.4)[/tex]

[tex]\implies 35.84+5.6J=89.6[/tex]

[tex]\implies 5.6J=53.76[/tex]

[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...

-2x+y=6  

Step-by-step explanation:

You subtract 2x from both sides to get -2x+y=6

:)

Answer:

-2x+y = 6

Step-by-step explanation:

Standard form is ax + by = c.

So we need to move the x term to the left side.

y = 2x + 6

Subtract 2x from each side

-2x + y = 6

Answer:

12520

Step-by-step explanation:

Firstly , we need to find 25²

25 × 25 = 625

Then let us multiply before we add on ,

20 × 25² = 20 × 625 = 12500

12500 + 20 = 12520

And this is the final answer.

Question

Step-by-step explanation:

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.

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.

Answer:

The probability that both cards that are drawn are hearts is 1/17.

Step-by-Step-Explanation:

First off, know that there are 13 heart cards in the deck of 52 cards. Therefore, the chance of pulling a single heart card is 13/52. Let's say we do pull a heart card. Since there is no replacement for the heart card taken out of the deck, we now have 12 heart cards out of a deck of 51 cards. The chance of pulling out a heart card in now 12/51. To find the probability that both cards drawn out are hearts, multiply the two fractions together: (13/52)⋅(12/51)=156/2652=1/17.

The transformation needed to show that both circles on the graph are similar is dilation

The equation of a circle that has its center to be (0,0) is:

[tex]x^2 + y^2 = r^2[/tex]

Where r represents the radius of the circle.

The radius can take any positive value.

Assume r = 5, then the equation becomes

[tex]x^2 + y^2 = 5^2[/tex]

[tex]x^2 + y^2 = 25[/tex]

The above can represent the equation of the Ferris wheel

A circle similar to the Ferris wheel can have the following equation

[tex]x^2 + y^2 = 7^2[/tex]

[tex]x^2 + y^2 = 49[/tex]

The above circle equation has a radius of 7, and it passes through the center

So, we have:

[tex]r = 5[/tex] -- radius of the Ferris wheel

[tex]R = 7[/tex] -- radius of the similar circle

Since both circles pass through the center, either of the circles can be dilated to the other
