Answer:

1961

Step-by-step explanation:

replace x with 8

25(8)^2-28(8)+585

25(64)-28(8)+585

1600-224+585

1961

f(8) = 1961.

The quadratic function given is: f(x) = 25x2 - 28x + 585

To predict f(x) when x = 8:

Substitute x = 8 into the function:

f(8) = 25(8)2 - 28(8) + 585

f(8) = 25(64) - 224 + 585

f(8) = 1600 - 224 + 585

f(8) = 1961

Therefore, f(8) equals 1961.

It is 24 yards long.

Let the width = x

Given that the rectangular field is 3 times as long as it is wide.

So, the length = 3x.

So area = Length * width = [tex](3x)*(x) = 3x^2[/tex].

Given:  it has an area of 192 square yards.

So,

[tex]3x^2=192\\x^2=64\\x=\sqrt{64}\\x=8[/tex]

So length = 3x = 3(8) = 24.

Answer:

negative infinity

Step-by-step explanation:

f(x) = 3 x^7

As x approaches - infinity we do not care about the 3 since it is positive

f(-inf) = (- inf)^7

We can take the negative out since it is to a negative power

f(-inf) = - (inf)^7

inf raised to a power is still infinity

F(-inf) = - inf

It will approach negative infinity

The last equation,

[tex]y+3=-6(x+9)[/tex]

To find which of the given equations represents a line that passes through the point (-9,-3) and has a slope of -6, we need to find an equation that can be satisfied by evaluating the given point.

We can see that the only equation that can be satisfied evaluating the point (-9,-3) is the last equation:

[tex]y+3=-6(x+9)[/tex]

Evaluating the point, we have:

[tex]-3+3=-6*(-9+9)[/tex]

[tex]0=-6*(0)[/tex]

[tex]0=0[/tex]

We can see that the equation is satisfied!

Also, we can see that evaluating the point into the other equations, they will not be satisfied.

Let's prove that:

Evaluating:

First equation:

[tex]y-9=-6(x-3)\\-3-9=-6*(-9-3)\\-12=-6*(-12)=72[/tex]

The equation is not satisfied.

Second equation:

[tex]y+9=-6(x+3)\\-3+9=-6*(-9+3)\\6=-6*(-6)=36[/tex]

The equation is not satisfied.

Third equation:

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

[tex]-3-3=-6(-9-9)[/tex]

[tex]-6=-6(-18)=108[/tex]

The equation is not satisfied.

Hence, the correct option is the last option, the equation that represents a line that passes through (–9, –3) and has a slope of –6 is the last equation:

[tex]y+3=-6(x+9)[/tex]

Hello There!

Answer:

The x-coordinate of Q is 5

Step-by-step explanation:

* Lets revise the division of the line segment

- If point (x , y) divides a line segment internally whose endpoints are

 (x1 , y1) and (x2 , y2) at the ratio m1 : m2 from (x1 , y1), then:

# [tex]x=\frac{m_{2}x_{1}+m_{1}x_{2}}{m_{1}+m_{2}}[/tex]

# [tex]y=\frac{m_{2}y_{1}+m_{1}y_{2}}{m_{1}+m_{2}}[/tex]

* Lets solve the problem

∵ Point R divides PQ in the ratio 1 : 3

∴ R is (x , y)

∴ P is (x1 , y1) and Q is (x2 , y2)

∴ m1 = 1 and m2 = 3

∵ x-coordinate of R is -1 and the x-coordinate of P is -3

∴ x = -1

∴ x1 = -3

- Use the rule above

∵ [tex]-1=\frac{(3)(-3)+(1)(x_{2})}{1+3}=\frac{-9+x_{2}}{4}[/tex]

- By cross multiplication

∴ (-1) (4) = -9 + x2

∴ -4 = -9 + x2 ⇒ add 9 to both sides

∴ 5 = x2

* The x-coordinate of Q is 5

the x-coordinate of point O is -2.5.

The question deals with dividing a line segment in a given ratio and finding the coordinates of a point. We are told that point R divides line segment PO in the ratio 1:3, the x-coordinate of R is -1, and the x-coordinate of P is -3. We are asked to find the x-coordinate of point Q, presumably typo for O.

Using the section formula, which states that the coordinates of a point dividing a line segment in the ratio m:n can be calculated using the formula (mx2 + nx1) / (m + n) for x-coordinate, here we have m = 1, n = 3, x1 (P's x-coordinate) = -3, and R's x-coordinate = -1. So, we can calculate the x-coordinate of point O (Q seems to be a typo in the question) as follows:

(1×(-1) + 3×(-3)) / (1 + 3) = (-1 - 9) / 4 = -10 / 4 = -2.5

Therefore, the x-coordinate of point O is -2.5.

Answer:

200 miles were driven

Step-by-step explanation:

We know that [tex]C (m) = 0.50m + 30[/tex] represents the cost of renting a car

Where m represents the number of miles driven

If we know that the cost was $ 130 then we can equal C(m) to 130 and solve for m.

[tex]C(m) =0.50m + 30=130[/tex]

[tex]0.50m + 30=130[/tex]

[tex]0.50m=130-30[/tex]

[tex]0.50m=100[/tex]

[tex]m=\frac{100}{0.50}[/tex]

[tex]m=200\ miles[/tex]

15/3 - 20 = -15

5 - 20 = -15

-15 = -15

Step-by-step explanation:

x/3 - 20 = -15

x/3 = -15 + 20

x/3 = 5

x = 15

Answer:

Half a block ( 0.5 or 1/2 )

Step-by-step explanation:

8 1/2  blocks can also be written as 8.5 blocks.

If Kira walks 8.5 blocks in 17 minutes [and continues to walk at this steady pace], divide 8.5 by 17.

8.5/17 = 0.5

So, Kira walked 0.5 or 1/2 blocks in a minute.

I hope this helps! :)

Kira walks at a rate of 0.5 blocks per minute when she walks 8 and a half blocks in 17 minutes.

Kira walks 8 and a half blocks in 17 minutes. To find out how many blocks she will walk each minute, we need to calculate the rate by dividing the total number of blocks by the total number of minutes:

Rate = Total Blocks Walked / Total Minutes

Rate = 8.5 blocks / 17 minutes

Rate = 0.5 blocks per minute.

Therefore, at a steady pace, Kira will walk half a block every minute.

Answer:

Only option C: The shortest side can equal 7 cm.

Step-by-step explanation:

Let the length of the shortest side be x cm, then the length of the longest side is 4x cm. Let the length of the middle side be y cm. Note that

[tex]x<y<4x[/tex]

The perimeter is

[tex]x+y+4x=60\\ \\5x+y=60[/tex]

A. The value x cannot be 40 cm, because then y is negative

B. If the longest side is 30 cm long, then

[tex]4x=30\\ \\x=7.5\\ \\y=60-5\cdot 7.5=22.5[/tex]

But

[tex]x+y=7.5+22.5=30\ cm[/tex]

This means that such triangle does not exist

C. If x=7 cm, then 4x=28 cm,

[tex]y=60-5\cdot 7=25\ cm[/tex]

Since,

[tex]7+25=32>28\\ \\7+28=35>25\\ \\25+28=53>7,[/tex]

such triangle exists and this option is possible

D. If x=25 cm, then y is negative

E. If x=5 cm, then 4x=20 cm and

[tex]y=60-5\cdot 5=35\ cm[/tex]

But this triangle does not exist, because [tex]5+20<35[/tex]

The longest side of this scalene triangle with a perimeter of 60 cm can equal 30 cm or the shortest side can equal 7 cm.

We can use the variables x, y and z to represent the shortest (x), medium (y) and longest (z) sides.  The perimeter of a triangle is found by adding together all of the sides; this gives us the equation

x + y + z = 60

We know that the longest side, z, is equal to 4 times the length of the shortest side, x.  This means that z = 4x; we can now write our equation as

x + y + 4x = 60

Combining like terms, we have

5x + y = 60

1.  Checking all of the possible options, we first determine if x can equal 40:

This would give us a negative side length, which is impossible.

2.  Let the longest side be 30 cm.  This means that the shortest side is 1/4 of that; 30÷4 = 7.5.  Using 7.5 for x,

This is within the range of acceptable side lengths, since it is between the smallest (7.5) and the largest (30).

3.  Let the shortest side be 7 cm.  This means x = 7:

This is between the longest side, 7 cm, and the longest side, 4(7) = 28 cm.  This is acceptable.

4.  Let the value of x be 25:

This will give us a negative value for the medium side, which is impossible.

5.  Let the shortest side be 5 cm.  This means x = 5:

This means the medium value, 35, would be greater than the longest side, 20; this is incorrect.

This means the correct options are that the longest side can be 30 cm and the shortest side can be 7 cm.

To solve the equation 10 ln(100x) - 3 = 117, first isolate the ln(100x) by adding 3 to both sides and then divide by 10. Exponentiate both sides with base e to remove the ln, and finally divide by 100 to solve for x.

We are given the equation 10 ln(100x) – 3 = 117. To solve for x, follow these steps:

10 ln(100x) = 120

ln(100x) = 12

100x = e^12

x = (e^12) / 100

Now, by using a calculator we can find the value of e^12 and then divide it by 100 to find the value of x.

The set of equations has an infinite number of solutions

Step-by-step explanation:

The system of linear equations represented by the following equations:

Line A: 4x + 4y = 16 and Line B: x + y = 4 are dependent.

This is because both equations represent the same line;

if we divide both sides of the equation of line A by 4, we would obtain

x + y = 4, which is basically the equation of line B

If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.

-75 = -8b - 7b

To solve for "b"  you must isolate it, meaning that "b" must be the only thing on the right side of the equation.

First you must combine like terms. Like terms are numbers that have matching variables OR are numbers with out variables. In this case the like terms are -8b and -7b, since they both have the variables "b" attached.

-8b + (-7b) = -15b

so...

-75 = -15b

Next, to completely isolate b, divide -15 to both sides. Since -15 is being multiplied by b, division (the opposite of multiplication) will cancel -15 out (in this case it will make -15 one) from the right side and bring it over to the left side.

-75/-15 = -15b/-15

5 = 1b

b = 5
