Which of following is an example of a quadratic inequality?

Answer: 9 feet below the surface.

Step-by-step explanation:

The scuba diver starts 40 ft below the surface. We can represent the position of the scuba diver as:

Position = -40ft

Where the negative sign is because it is below the surface of the water, so

"He swam up 12 feet to see a unique fish."

Now we need to add 12ft

Then his new position is:

Position = -40ft + 12 ft = -28ft

"He followed the fish down 8 feet.

Now we need to subtract 8ft

His new position is:

Position = -28ft - 8 ft = -36 ft

"Then he followed the fish up 27 feet."

Now we add another 27 ft.

The final position will be:

Position = -36ft + 27ft = -9ft

Then the final position of the scuba diver is -9ft, that means that he is 9 feet below the surface.

Answer:

Price of bracelet =  $(25 + 5c)

Step-by-step explanation:

As given,

A bracelet = 1 chain + Number of charm selected by customer

Also given,

Price of chain = $25

Price of each charm = $c

As,

we have to write equation for a bracelet with 5 charm

So,

Price of bracelet = Price of 1 chain + Price of 5 charm

As

Price of 1 charm = $c

⇒Price of 5 charm = $5×c = $5c

∴ we get

Price of bracelet = $25 + $5c = $(25 + 5c)

Answer:

Step-by-step explanation:

The ratio of the larger to the smaller corresponding sides is ...

  12.5/5 = 2.5

That means ...

  x = 2.5 × 4 = 10

  y = 2.5 × 3 = 7.5

A number line with a closed dot at -4 is shaded to the right. Option A is correct.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
Given inequality,
c – 12 ≥ –16

Add 12 on both sides
c ≥ -4

So the required number line would be as a closed dot at -4 and shaded to the right.

Thus, A number line with a closed dot at -4 is shaded to the right. Option A is correct.

Answer:

161

Step-by-step explanation:

Given the functions

f (x) = 2x^2 – 1

g(x) = 3x

we are to find f(g(3))

First look for the composite function f(g(x))

f(g(x)) = f(3x)

f(3x)  = 2(3x)² - 1

f(3x)  = 2*9x² - 1

f(3x)  = 18x² - 1

f(g(x)) =  18x² - 1

Substitute x  = 3 into the result

f(g(3)) = 18(3)² - 1

f(g(3)) = 18*9- 1

f(g(3)) = 162-1

f(g(3)) = 161

Hence f(g(3)) is 161

Answer:

Step-by-step explanation:

An escalator at a shopping center is 200.75 feet long and rises at an angle of 15⁰. What is the vertical rise of the escalator? Round to hundredths place

The horizontal distance that the ramp will take up is a) 22.9 ft.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, The vertical or opposite distance is 2 feet and it has an angle of 5°.

∴ The horizontal or adjacent distance can be obtained by tan(theta).

Assuming horizontal distance to be x feet.

∴ tan(5°) = 2/x feet.

x = 2/tan(5°).

x = 22.9 feet.

Answer:

x=1

Step-by-step explanation:

you would change it to 5x-4(-3x+5)=-3, because you put the info for the first equation into the second equation.

5x-4(-3x+5)=-3

5x+12x-20=-3

17x-20=-3

17x=17

x=1

Answer:

(1,2)

Step-by-step explanation:

1) To solve using substitution, first isolate one of the variables in one of the equations. However, the y in y = -3x + 5 has already been isolated, so we don't need this step. Instead, take that value of y and substitute it for the y in the other equation, 5x - 4y = -3. So, substitute -3x + 5 for the y in 5x - 4y = -3 and solve:

[tex]5x-4(-3x+5)= -3\\5x+12x-20=-3\\17x-20=-3\\17x = 17\\x = 1[/tex]

2) So, x = 1. Now, take that value of x and substitute back into any of the equations to find the y value. (I chose to substitute it into y = -3x + 5, but either choice is fine). So, substitute 1 for the x in y = -3x + 5 and solve:

[tex]y = -3(1)+5\\y = -3+5\\y = 2[/tex]

So, y = 2. Thus, by knowing both x and y values, the solution would be (1,2).

Answer:

the area of the square is 1cm^2

Step-by-step explanation:

The computation of the area of the square is given below:

As we know that

Area of the square = side^2

Also in the square four sides are equal

So

= 1cm^2

= 1cm^2

hence, the area of the square is 1cm^2

Step-by-step explanation:

Here, we want to get the height of the cone

radius = diameter/2

r = 12/2 = 6 m

To get this, we use the formula for the volume

V = 1/3 * pi * r^2 * h

133 = 1/3 * 3.142 * 22/7 *6^2 * h

h = 1.12 m

Answer:

  y = 3

Step-by-step explanation:

The slope formula can be used to find the slope of the parallel line.

  m = (y2 -y1)/(x2 -x1)

  m = (1 -1)/(7-(-2)) = 0

The line is a horizontal line, so the y-intercept must be chosen to match the y-value of the given point.

  y = 3

_____

If you want to see the slope of zero in the slope-intercept form equation, you can write the equation as ...

  y = 0x +3

It is pretty unusual to keep 0 terms in an equation. Usually, they are eliminated when the equation is simplified.
