Answer:

24=10

Step-by-step explanation:

The value of y when  x = 10 is 5/4

If y varies directly as x, this is expressed as:

[tex]y \alpha x\\y = kx\\[/tex]

where

k is the constant of proportionality

If y = 3 when x = 24, then:

3 = 24k

k = 3/24

k = 1/8

In order to get the value of x when y = 10

Recall that y = kx

y = 1/8 * 10

x = 10/8

y = 5/4

Hence the value of y when  x = 10 is 5/4

Answer:

Part A

The degree of f(x) is 7

Part B

The leading coefficient negative

Part C

There are 5 distinct real zeros and 2 relative minimum values

Step-by-step explanation:

From the of a polynomial from a graph of the polynomial, starting from the left, we have;

1) The graph touches the x-axis (horizontally) and then crosses, which gives a multiplicity of 3

2) The graph crosses the x-axis once going upwards with a multiplicity of 1

3) Next, the graph crosses the x-axis once going downwards with a multiplicity of 1

4) Next, the graph crosses the x-axis once going upwards with a multiplicity of 1

5) Finally, the graph crosses the x-axis once going downwards with a multiplicity of 1

Part A

The degree of f(x) is therefore, 3 + 1 + 1 + 1 + 1 = 7

Part B

The leading coefficient of a polynomial that has an odd degree power with a graph falls to the right and rises to the left, the leading coefficient is negative;

Part C

The number of zeros = 7 zeros

The number of identical zeros = 3 identical zeros

∴ The number of distinct zeros are 7 zeros - 2 identical zeros = 5 distinct zeros

The graph continues from +∞ to -∞, therefore, the number relative minimum value of the polynomial are the two minimum values

The number of relative minimum values = 2

Therefore, there are 5 real distinct zeros and 2 relative minimum values

Answer:

y= -x-8

Step-by-step explanation:

The ones in the equation are in subscript, couldn't get the equation creator to work properly....DO NOT multiply by one, they are merely subscript meant to help you identify which pair to use.

y-y1=m(x-x1)

-5=x1

-3=y1

-1=m

y- -3=-1(x- -5) then you arrive at y+3=-1(x+5)

y+3=-x-5 now you isolate the y on the left y=-x-8

Answer:

The diameter of Circle P is the same length as the radius of Circle Q.

Step-by-step explanation:

The radius of Circle Q is half of 52cm. So you would divide 52 by 2 and get 26cm as the radius of Circle Q. Therefore, the length of the diameter of Circle P is the same length as the radius of Circle Q.

Step-by-step explanation:

You make a proportion 9/6=15/x then multiply 6 and 15 and divide it by 9

The height the 15 ft building touches the building is approximately 10 ft.

The ladder is 9 ft tall and leaning on a wall that is 6 ft above the ground.

The situation forms a right angle triangle.

Therefore, let's find the angle made by the 9 ft ladder and then use it to find the height the 15 ft ladder touch the building.

Using trigonometric ratios,

let

∅ = angle

tan ∅ = opposite / adjacent

tan ∅ = 6 / 9 = 2 / 3

∅ = tan⁻¹ 0.6666666

∅ = 33.6900672615

Therefore, the height the 15 ft ladder touch building can be calculated as follows:

tan 33.69 = h / 15

h = 15 × 0.66666496431

h = 9.99997446476

h ≈ 10 ft.

The number that is less than 1.25 is 1.2.

The given number is a decimal.  A decimal is a number that is made up of a whole number and fractional parts divided by a point. For example in 1.25, 1 is the whole number and 2 and 5 are the fractional parts.

The number that is greater than 1.25 would have either its tenth value greater than 2 or its hundredth value greater than 5. The number less than 1.25 would have either its tenth value less than 2 or its hundredth value less than 5.

Answer:

Step-by-step explanation:

"Alternate" means the angles are on opposite sides of the transversal.

"Consecutive" means the angles are on the same side of the transversal. Sometimes, these are called "same-side" angles.

"Exterior" means the angles are outside the parallel lines.

"Interior" means the angles are between the parallel lines.

"Corresponding" means the angles are in the same direction from the point of intersection.

The third model represents the quotient, option C is correct.

A division is a process of splitting a specific amount into equal parts.

In division, we divide a number by any other number to get another number as a result.

The number which is getting divided here is called the dividend.

The number which divides a given number is the divisor.

And the number which we get as a result is known as the quotient.

Hence, the third model represents the quotient, option C is correct.

Answer:

B) (-2,1)

Step-by-step explanation:

In order to find a solution to a system of equations, substitute the point's x and y values into both of the equations, solve, and see if it makes the equation true.

1) Let's try the point (-2,1). First, substitute its x and y values into the first equation, 3x - 3y = -9. Thus, substitute -2 for x and 1 for y in the equation and solve:

[tex]3x-3y = -9\\3(-2)-3(1) = -9\\-6 - 3 = -9 \\- 9 = -9[/tex]

-9 does equal -9, thus (-2, 1) makes the first equation true.

2) Now, do the same thing but with the second equation, 2x + y = -3. Again, substitute -2 for x and 1 for y and solve:

[tex]2x + y = -3\\2(-2) + (1) = -3\\-4 + 1 = -3\\-3 = -3[/tex]

-3 does equal -3, thus (-2, 1) makes the second equation true.

By substituting its values into both equations, we saw that it made both equations true. Thus, (-2,1) is the answer.

Answer:

About 6 hours.

Step-by-step explanation:

The cylinder has a diameter of 10 meters and a depth of 1.4 meters.

First, we can find the volume of the cylinder, given by the formula:

[tex]V=\pi r^2h[/tex]

Where r is the radius and h is the height (or depth, in this case).

Since our diameter is 10, our radius is 5.

Therefore, the volume of the cylinder will be (using 3.14 as π):

[tex]V=(3.14)(5)^2(1.4)=109.9\text{ meters} ^3[/tex]

Since water is pumped at a rate of 18 cubic meters per hour, it will take then:

[tex]109.9/18=6.10\overline{5}\approx 6\text{ hours}[/tex]

So, it will take about 6 hours for the water to completely fill the pool.
