Step-by-step explanation:

Y E S

I love simple math.

3.25$ to wash the car.

60 seconds: 1 quarter

how many quarters is 3.25?

4 quarters per dollar. so it'd be 13 quarters, then do 13*60=how many seconds u got. 780 seconds. I think you can do 780/60

HINT: hey, psst, it's 13 minutes. : D

A nest of ants has been growing exponentially in such a way that its population, P, as a function of w weeks is given by P(w)=24
Hunter-Best [27]

Answer:

0.9%

Step-by-step explanation:

Given that:

A nest of ant is represented by the exponential growth function :

P(w)=24,000(1.063)^w

Where w = number of weeks

Recall :

Growth function is generally represented as :

P(t) = A(1 + r)^t

Where ; A is the initial population figure; r = growth rate and t = time

Hence, the growth rate per week of the function given is :

(1 + r) = 1.063

r = 1.063 - 1

r = 0.063

Number of days in a week = 7

Hence, growth rate per day = r /7

0.063 / 7

= 0.009

(0.009 * 100%) = 0.9%

Find all the values of x where the tangent line is horizontal.<br> 2x^3+36x^2+192x+12
Afina-wow [57]
At x = -4 and -8
Take the derivative of the given equation to find rate of change of the graph.
f'(x) = 6x^2 + 72x + 192
At a horizontal tangent, f'(x) = 0, so set the equation equal to 0 and solve. Eventually you get x = -4 and -8

The point V(4, –1) is rotated 90° clockwise around the origin. What are the coordinates of its image V’?
Verizon [17]

Answer:

(-1,-4)

Step-by-step explanation:

Because it is a rotation that turns both the x and y values the two swap places. The x value become negative because before it was in quadrant 4 where there was still a positive chance but rotating the point clockwise puts it into the third quadrant where there are only negatives.

You and a friend are heading to Frankie's Fun Park (Columbia, SC). You have $100 for the day, and plan to spend your time riding
Rufina [12.5K]

Answer:

8r + 6s = 100 --- (a)

s = -2 ---- (b)

Step-by-step explanation:

Given

Per ride (r) = $8

Per baseballs (s) = $6

Total = $100

Required

Represent using an equation

If 1 ride is $8.

r rides would be 8r

If 1 baseball is $6

s baseballs would be 6r.

So, total is:

8r + 6s = 100

Solving (b):

Value of s when r = 14

8r + 6s = 100

Substitute 14 for r

8 * 14 + 6s = 100

112+ 6s = 100

Solve for 6s

6s = 100 - 112

6s = -12

Solve for s

s = -12/6

s = -2
