T he equation for a parabola with directrix y = –p and focus (0, p) is:1.What is the parabola’s line of symmetry?

y-axis
x-axis
x = p
x = -p

Answers

Answer 1

Answer:

The equation for a parabola with directrix y = –p and focus (0, p)

The distance between vertex and directrix is P

Also the distance between vertex and focus is also P

Focus (0,p) so focus lies on y axis

Directrix line is paralled to focus point

So Directex crosses the x axis .

Hence line of symmetry lies is the y-axis.

The graph is attached below.

Mrs. Gregory, the golf course superintendent at a country club, plans to reseed the putting green of the first hole. The circular putting green has a diameter of 38 ft.What is the area of the putting green?

Use π=3.14. Round to the nearest tenth

Answers

Answer:

The area of the putting green is 1133.5 square feet.

Step-by-step explanation:

Area of a circle:

The area of a circle is given by:

$A = \pi r^2$

In which r is the radius, which is half the diameter.

The circular putting green has a diameter of 38 ft.

This means that $r = (38)/(2) = 19$

What is the area of the putting green?

$A = \pi r^2 = 3.14 * 19^2 = 1133.5$

The area of the putting green is 1133.5 square feet.

Answer:

1133.5 is the answer.

Answer:

A = 1.5
B = -1/3
C = -4/3

Step-by-step explanation:

For A:

A is smack in the middle of 1 and 2, so it it 1 1/2 or 1.5 (same thing)

For B:

Each tick mark between the numbers represents 1/3
B is on the first tick mark between 0 and -1, so therefore it is -1/3

For C:

C is on the first tick mark between -1 and -2
That means C is -1 1/3
-1 1/3 = -4/3

I hope this helps!

Answer:

A ----> +1.5

B------> -0.33

C-------> -0.1322

Step-by-step explanation:

$A\ is\ +1.5\ as\ it\ is\ 1.5\ units\ upwards(positively)\ from\ 0.\nB\ is\ -(1)/(3)\ as\ it\ equates\ to\ -0.33\ which\ is\ between\ 0\ and\ -1.\nC\ is\ -(4)/(3)\ as\ it\ equates\ to\ -1.322\ which\ is\ between\ -1\ and\ -2.\n$

Solve for W in the scientific formula c= wtc/1,000

Answers

Answer:

1000/t=w

Step-by-step explanation:

The first thing we need to do is, multiply 1000 to both sides,

c(1000)=wtc

now we need to divide both sides by tc

c(1000))/(tc)=w

The c's on the left side will cancel out

1000/t=w

Answers

Based on my little knowledge of statistics
4.
It's 8!/4!= 1680
(the exclamation point is basically the number of probabilities in the combination)
5.
(speculation) It's 10!-6!= 3,628,080
plus
8!-6!=39,600
equals
(3,628,080 + 39,600) / 6! = 5094
(the 6! is the amount of drink combinations you are limited to)
FYI- you can use the exclamation mark on your phone calculator, either swipe to side or press the ''extras'' button

I think #5 is actually 5096?
10x9x8x7=5040
8x7=56
5040+56=5096
