look at the map below. which is the distance between kensington and greenwich?​

1) What are the zeros of the function?

smaller r: -11, larger r: -14

2) What is the vertex of the parabola

Vertex: (-12.5, 3)

1. Zeros:

The zeros of the function occur when G(r) = 0. So we need to solve the equation:

-(r + 11)(r + 14) = 0

Since the product of two factors is zero when one or both factors are zero, we can set each factor equal to zero and solve for r:

r + 11 = 0 --> r = -11 (smaller r)

r + 14 = 0 --> r = -14 (larger r)

2. Vertex:

The function is given in factored form, which makes finding the vertex a bit easier. The vertex of a parabola in factored form is exactly between the two zeros.

Therefore, the x-coordinate of the vertex is:

(smaller r + larger r) / 2 = (-11 - 14) / 2 = -12.5

To find the y-coordinate (i.e., the function's value at the vertex), we can plug the x-coordinate of the vertex back into the function (G(r)). However, since the function is multiplied by -1, it might be easier to use one of the original zeros (say, r = -11).

G(-11) = -(-11 + 11)(-11 + 14) = 3 (notice how the negative sign cancels out)

Answer:

20% increase

Step-by-step explanation:

Percent increase = (difference) / original *100 percent

                             = (12-10)/10 * 100percent

                             = 2/10 *100 percent

                             = 1/5 * 100 percent

                              =.2 * 100 percent

                              = 20%

Step-by-step explanation:

To determine if (1, 2) is a solution to the system

Substitute x = 1, y = 2 into the inequalities and check their validity.

y > 2x → 2 > 2 ← incorrect statement

x + y < 3

1 + 2 < 3 → 3 < 3 ← incorrect statement

(1, 2) is not a solution to either inequality → d

Answer:

x = 12 or A

Step-by-step explanation:

Tangents from an exterior point to the circumference of a circle are equal

Since one of the tangents = 17, the other one must as well

x + 5 = 17            Subtract 5 from both sides.

x + 5-5 = 17-5

x = 12

The answer is A

Answer:

x² + 2x + [3\x - 1]

Step-by-step explanation:

Since the divisor is in the form of x - c, use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:

1| 1 1 -2 3

↓ 1 2 0

------------------

1 2 0 3 → x² + 2x + [3\x - 1]

You start by placing the c in the top left corner, then list all the coefficients of your dividend [x² + 5x - 36]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder, which in this case is a 3, so what you is set the divisor underneath the remainder of 3. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an x², 2 becomes 2x, and the remainder of 3 is set over the divisor, giving you the other factor of x² + 2x + [3\x - 1].

Answer:

The coordinates of the midpoint of the line segment that has endpoints (2,3) and (10,3) are (6,3).

Suppose we've two endpoints of a line segment as A(p,q), and B(m,n), then let the midpoint be M(x,y) on that line segment. Then, its coordinates are x =(p+m)/2 and y = (q+n)/2.

Given the endpoints of the line segment are A(-3,4) and B(-6,-1), then the coordinates of the midpoint will be,

x = (2+10)/2 = 12/2 = 6

y = (3+3)/2 = 6/2 = 3

Hence, the coordinates of the midpoint of the line segment that has endpoints (2,3) and (10,3) are (6,3).

Step-by-step explanation:

Download song .50

Download album = 4

Let s = number of songs

a = number of albums

She can spend 15 dollars

.5s +4a =15

If she downloads 6 songs, let s=6

.5(6) +4a = 15

3+4a = 15

Subtract 3 from each side

3-3+4a = 15-3

4a = 12

Divide by 4

4a/4 =12/4

a=3

She can buy 3 albums

If she downloads 1 album, let a=1

.5(s) +4(1) = 15

Answer:

The correct answer is option B.

Step-by-step explanation:

The given rational expression is:

[tex]\frac{x^2-4}{x^2+5x+6}[/tex]

Factor the numerator and the denominator:

[tex]\frac{x^2-2^2}{x^2+2x+3x+6}[/tex]

Factor the numerator using difference of two squares and the denominator using factorization by grouping.

[tex]\frac{(x-2)}{x(x+2)+3(x+2)}[/tex]

[tex]\frac{(x-2)(x+2)}{(x+2)(x+3)}[/tex]

This function is defined if and only if the denominator is not zero.

That is: (x+3)(x+2)≠0.

x≠-2,x≠-3

We simplify now to obtain:

[tex]\frac{x-2}{x+3}[/tex]

The correct choice is the second option.

Option B is correct.

Answer:

8 cups

Step-by-step explanation:

The number of cups of Gatorade served to the players during the last game was 8 cups.

To solve the problem, we need to determine how many cups are in half a gallon, given that 1 cup is equal to 1/16 of a gallon.

First, we establish the conversion factor between cups and gallons:

1 cup = 1/16 gallon

Now, we need to find out how many cups are in 1/2 gallon. To do this, we multiply the amount of Gatorade used in the last game by the conversion factor:

Cups served = (1/2 gallon) * (16 cups / 1 gallon)

Performing the multiplication:

Cups served = 1/2 * 16

Cups served = 8 cups

Therefore, 8 cups of Gatorade were served to the players during the last game.

Answer:

perimeter = 10x + 2

area = 6x^2 + 2x

perimeter = 52

area = 160

Step-by-step explanation:

perimeter = 2 * length + 2 * width

perimeter = 2(3x + 1) + 2(2x)

perimeter = 6x + 2 + 4x

perimeter = 10x + 2

area = length * width

area = (3x + 1)(2x)

area = (2x)(3x + 1)

area = 6x^2 + 2x

For x = 5:

perimeter = 10x + 2 = 10(5) + 2 = 50 + 2 = 52

area = 6x^2 + 2x = 6(5^2) + 2(5) = 6(25) + 10 = 150 + 10 = 160

Answer:

After 7.5 seconds and a height of 0

Step-by-step explanation:

The time taken for the bolt to hit the elevator is 3 seconds, at a height of 60 feet.

Given that the elevator height is h(t)=20t while the bolt height is given by h(t)=-16t² + 200.

At the point when the bolt hit the elevator, they would be at the same height, hence:

-16t² + 200 = 20t

16t² + 20t - 200 = 0

t = -4.2 or t = 3

Therefore the time taken for the bolt to hit the elevator is 3 seconds, the height is:

h(3) = 20(3) = 60 feet

The time taken for the bolt to hit the elevator is 3 seconds, at a height of 60 feet.

Part 3) The system is solved by graphing

The graph in the attached figure

Step-by-step explanation:

Part 1) Solve the system by elimination

Let

x----> the cost per can of grape juice

y----> the cost per can of apple juice

we know that

[tex]6x+4y=13.10[/tex] -----> equation A

[tex]4x+6y=13.10+0.60[/tex]

[tex]4x+6y=13.70[/tex]  -----> equation B

Solve the system by elimination

Multiply the equation A by -6 both sides

[tex]-36x-24y=-78.6[/tex] -------> equation C

Multiply the equation B by 4 both sides

[tex]16x+24y=54.8[/tex] -------> equation D

Adds equation C and equation D

[tex]-36x-24y=-78.6\\16x+24y=54.8\\----------\\-36x+16x=-78.6+54.5\\-20x=-23.8\\x=1.19[/tex]

Substitute the value of x in the equation A

[tex]6(1.19)+4y=13.10[/tex]

[tex]4y=5.96[/tex]

[tex]y=1.49[/tex]

therefore

The cost  per can of grape juice is [tex]\$1.19[/tex]

The cost per can of apple juice is [tex]\$1.49[/tex]

Part 2) Solve the system by substitution

Let

x----> the cost per can of grape juice

y----> the cost per can of apple juice

we know that

[tex]6x+4y=13.10[/tex]    

[tex]4y=-6x+13.10[/tex]

[tex]y=-1.5x+3.275[/tex] -----> equation A

[tex]4x+6y=13.10+0.60[/tex]

[tex]4x+6y=13.70[/tex]  

[tex]6y=-4x+13.70[/tex]

[tex]y=-(4/6)x+13.70/6[/tex]

[tex]y=--0.67x+2.28[/tex] -----> equation B

Substitute equation B in equation A and solve for x

[tex]-0.67x+2.28=-1.5x+3.275[/tex]

[tex]1.5x-0.67x=3.275-2.28[/tex]

[tex]0.83x=0.995[/tex]

[tex]x=1.19[/tex]

Find the value of y

Substitute the value of x in the equation A

[tex]y=-1.5(1.19)+3.275=1.49[/tex]

therefore

The cost  per can of grape juice is [tex]\$1.19[/tex]

The cost per can of apple juice is [tex]\$1.49[/tex]

Part 3) Solve the system by graphing

we have

[tex]y=-1.5x+3.275[/tex] -----> equation A

[tex]y=-(4/6)x+13.70/6[/tex] -----> equation B

Remember that

The solution of the system of equations is equal to the intersection point both lines

The solution is the point [tex](1.19,1.49)[/tex]

see the attached figure

therefore

The cost  per can of grape juice is [tex]\$1.19[/tex]

The cost per can of apple juice is [tex]\$1.49[/tex]

2 > -3     (2 is greater than -3, this is true)

-7 < -5    (-7 is less than -5, this is true because -7 is more negative than -5)

-9 < 1       (-9 is less than 1, this is true)

0 < -4      (0 is less than -4, this is false because 0 is greater than -4)

Among the comparisons given, "0 < -4" is incorrect.

The student is asking which comparison is not correct. After evaluating each comparison, it becomes clear that 0 < -4 is not correct because 0 is not less than -4; in fact, 0 is greater. Other comparisons such as 2 > -3, -7 < -5, and -9 < 1 are all correct, as in each case, the number on the left side of the inequality is indeed larger (or smaller, for negative numbers) than the number on the right side as the symbol indicates.

To understand why 0 < -4 is incorrect, consider the number line where any number to the right is greater than the number to the left. Zero (0) lies to the right of any negative number, including -4, which means it is greater, not less.

Answer:

The probability your mean age will be at least 28 is 83%

Step-by-step explanation:

Let X denote the ages of all new employees hired during the last 10 years , then X is normally distributed with;

a mean of 31

a standard deviation of 10.

The sample size obtained is 10 employees. This implies that the sampling distribution of the sample mean will be normal with;

a mean of 31

a standard deviation of [tex]\sqrt{10}[/tex]

The sample mean is a statistic and thus has its own distribution. Its mean is equal to the population mean, 31 and its standard deviation is equal to [tex]\frac{sigma}{\sqrt{n} }[/tex]

where sigma is the population standard deviation, 10 and n the sample size which in this case is 10. [tex]\frac{10}{\sqrt{10} }=\sqrt{10}[/tex]

We are required to find the probability that this sample mean age will be at least 28;

P(sample mean ≥ 28)

Since we know the distribution of the sample mean we simply standardize it to obtain the z-score associated with it;

P(sample mean ≥ 28)

= [tex]P(Z\geq \frac{28-31}{\sqrt{10} } )=P(Z\geq -0.9487)[/tex]

Step-by-step explanation:

3x + 2y = 5

4x − 9y = −5

Multiply the first equation by 4 and the second equation by -3 so we can eliminate x

4(3x + 2y) = 5 *4

Distribute

12x +8y = 20

-3(4x − 9y) = −5*-3

-12x +27y = 15

Add the two new equations together

12x +8y = 20

-12x +27y = 15

------------------------

35y = 35

Divide by 35

35y/35 = 35/35

y=1

Now we can find x

3x+2y =5

3x+2(1) =5

3x +2 =5

Subtract 2 from each side

3x+2-2=5-2

3x=3

Divide by 3
