Which expression is equivalent to ?

9514 1404 393

Answer:

Step-by-step explanation:

1. The point halfway between the focus and directrix is the origin. That is, the vertex of the parabola is the origin. Then its equation can be written ...

  y = 1/(4p)x²

where p is the distance from the vertex (origin) to the focus. Here, that distance is -6, so 4p = -24 and the parabola's equation is ...

  y = -1/24x²

__

2. Same deal. The vertex is the origin, but this time the focus is above the origin by 9 units. Then the equation is ...

  y = 1/36x²

Answer:

81.75

Step-by-step explanation:

First, find the median of all the answers.

78.25,  77.75, and 84 = 80 (median)

now that we know 80 is the median, we will add it to our solution.

And still, there is no OTHER TEST in to make this stay 80.

78.25, 77.75, 84, and 80 = 79.125

since this is incorrect, we go higher.

78.25, 77.75, 84 and 81 = 79.625

since this is also incorrect, we go higher.

78.25, 77.75, 84 and 82 = 80.125

since this is higher and incorrect, we will go lower to 81.5.

78.25, 77.75, 84 and 81.5 = 79.875

since this is lower AND 82 is not the correct solution, we will go up by 0.25.

78.25, 77.75, 84 and 81.75 = 80

To check, we will do the problem again.

78.25, 77.75, 84 and 81.75 = 80

So, the solution is 81.75

Hey there!

32 + 3(6 − 22) ÷ 6

= 32 + 3(-16) ÷ 6

= 32 + (-48)/6

= 32 + (-8)

= 32 - 8

= 24

Therefore, your answer SHOULD BE: 24

Good luck on your assignment and enjoy your day!

O - of

D - division

M - multiply

A - addition

S - subtract

Let's solve

32 +3 (6-22) ÷ 6

32 + 3 × (-16) ÷ 6

32 - 48 ÷ 6

The number of arrangements is an illustration of permutations.

The number of arrangement is 5040

The given parameter is:

[tex]n = 7[/tex] --- number of days

[tex]r = 7[/tex] --dinners for 7 days

So, the number of different arrangement is

[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]

Substitute known values

[tex]^7P_7 = \frac{7!}{(7 - 7)!}[/tex]

[tex]^7P_7 = \frac{7!}{0!}[/tex]

[tex]^7P_7 = \frac{5040}{1}[/tex]

[tex]^7P_7 = 5040[/tex]

Hence, the number of arrangement is 5040

Answer:

  y = 2·2^x

Step-by-step explanation:

When the exponential function is of the form ...

  y = a(b^x)

The value of 'a' is the value of y when x=0. The table tells us a = 2.

The value of 'b' is the ratio between values of y when their corresponding x-values differ by 1. The table tells us b = (4/2) = 2.

Then the exponential function describing the table is ...

  y = 2(2^x)

Answer: y+-1m -1

Step-by-step explanation:

The number of miles that he will have traveled after 3.5 hours of driving on the highway is 227.5 miles.

The function given to solve the question is: f(x) = 65x

where, x = number of hours

Therefore, when he travelled for 3.5 hours, the number of miles will be gotten by multiplying 65 by 3.5.

f(x) = 65x

= 65 × 3.5

= 227.5 miles.

Therefore, the number of miles that he will have travelled after 3.5 hours of driving on the highway is 227.5 miles.
