Answer:

The characteristics of the parabola are;

1) The vertex of the parabola, (h, k) = (-8, 1)

2) The parabola opens left

3) The axis of symmetry is, y = 1

4) The equation of the parabola is x = -y²/8 + y/4 - 65/8

5) The end points of the latus rectum are (-10, -3), and (-10, 5)

Step-by-step explanation:

The focus of the parabola = (-10, 1)

The directrix of the parabola, x = -6

The directrix; x = h - p

The focus, F(h + p, k)

Therefore, we have;

h + p = -10

h - p = -6

2·h = -16

h = -8

p = -10 - h = -10 - (-8) = -2

p = -2

Therefore, we have;

1) The vertex of the parabola, (h, k) = (-8, 1)

2) Therefore, the parabola opens left

3) The axis of symmetry is the line y = 1

For P < 0, the equation of the parabola is of the form (y - k)² = 4·p·(x - h)

Therefore, the equation of the parabola is (y - 1)² = 4×(-2)×(x - (-8))

(y - 1)² = 4×(-2)×(x - (-8)) = y² - 2·y + 1 = -8·x - 64

∴ y² - 2·y + 1 + 64 = -8·x

x = -y²/8 + y/4 - 65/8

4) The equation of the parabola is x = -y²/8 + y/4 - 65/8

5) The end points of the latus rectum are (h + p, k + 2·p) and (h + p, k - 2·p)

Therefore, the end points of the latus rectum of the given parabola are;

(-8 + (-2), 1 + 2×(-2)) and (-8 + (-2), 1 - 2×(-2))

(-10, -3), and (-10, 5)

Now the equation to find the graph does not matter to find the solution right now. Only the graph will be need as long as the graph is already filled. To find the solution, all you have to do is find the point where the two lines cross. On this graph, you can see that point in the two lines where there is a circle.

The net worth of Kareem, if he satisfies the conditions given above, will amount to approximately $3,250. Therefore, the option B holds true.

A net worth of an individual can be referred to or considered as the total of the amount of monies owned by him or her in personal capacity. In simplest of the words, it can be said that the assets of a person are a forming part of his or her net worth.

In the conditions given above, we can ascertain Kareem's net worth as a total of his assets, i.e., the sum of down payment and balance in savings account less the liability of credit card.

3000 + 550 – 300 = $3,250.

Therefore, the option B holds true and states regarding the significance of the net worth of Kareem in the conditions given above.

Step-by-step explanation:

Answer:

8.06

Step-by-step explanation:

From the Pythagorean theorem, x = sqrt(4^2+7^2) which is sqrt(16+49) = sqrt(65) = 8.06

Answer:

The true answer is actually \sqrt{65}

Step-by-step explanation:

4^2+7^2=x^2

Switch sides: x^2=4^2+7^2

After everything is squared: x^2=16+49

So..x^2=65 OR \sqrt{65}

Answer:

P(red) = 1/6

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

One bag contains black, red and green pearls in a ratio of 3:2:7.

So

[tex]\frac{3}{3+2+7} = \frac{3}{12}[/tex] of the pearls are black

[tex]\frac{2}{3+2+7} = \frac{2}{12}[/tex] of the pearls are red.

[tex]\frac{7}{3+2+7} = \frac{7}{12}[/tex] of the pearls are green.

P (red)

For each 12 pearls, 2 are red. So

P(red) = 2/12 = 1/6

Answer:

The initial (x, y) value of the data is (0, 16)

Step-by-step explanation:

The given data is presented here as follows;

[tex]\left\begin{array}{cc}x&y\\-5&6\\-4&8\\-3&10\\-2&12\\-1&14\end{array}[/tex]

From we data, we have a common first difference in the 'y' values of 2, therefore, we have a straight line graph

The slope of the graph, m = (14 - 6)/(-1 - (-5)) = 2

The equation of the straight line graph in point and slope form is;

y - 14 = 2 × (x - (-1)) = 2 × (x + 1)

Therefore, the equation of the straight line graph in slope and intercept form is given as follows;

y - 14 = 2 × (x + 1)

y = 2·x + 2  + 14 = 2·x + 16

y = 2·x + 16

The initial value of the graph when x = 0 is therefore given as follows;

y = 2·x + 16 = 2 × 0 + 16 = 16

y = 16 when x = 0

The initial value of the graph is (0, 16)

Therefore, the initial value of the given data is x = 0, y = 16.

Answer:

Merton will have about 6,000 more people than Hapville

Step-by-step explanation:

Merton

y = 12,000(1.04)^(30)

y = 12,000(3.24339)

y = 38,920.77012

Hapeville

y = 18,000 + (30 x 500)

y= 18,000 + 15,000

y = 33, 000

Merton - Hapeville

38,920.77012 - 33,000 = 5920.77012

Therefore Merton will have about 6,000 more people than Hapville

Answer:

$35.53

Step-by-step explanation:

1. Divide what Kelly paid by the amount of gallons she paid for.

a. 29.26 divided by 14 = 2.09

2. Take the amount per gallon and multiply it by 17.

a. 17 times 2.09 = 35.53

So it will be $35.53 for 17 gallons of gas.

Answer:

35.53

Step-by-step;

So Kelly got 14 gallons of gas for 29.26. She is wondering how much it would be to fill it up to 17 gallons. So what you have to do is first find out how much the gas cost per gallon. so you would divide 29.26 by 14 to get 2.09. so now that you have how much it is per gallon all you have to do is multiply the amount per gallon {2.09} by 17. so when you multiply 2.09 by 17 you get 35.53. So Kelly had to pay 35.53 for a 17 gallon tank of gas!

Actually Welcome to the Concept of the parallel,lines

Since both the angles are corresponding angles, hence they are equal,so we get as,

7x+40 = 3x+112

===> 7x - 3x = 112-40

===> 4x = 72

===> x = 72/4 => 18

hence x = 18°

now angle A = 7(18)+40

A = 166°

hence, A = 166°
