5. suppose it costs $4 for a ticket to the school dance. at that price, the dance committee sells 200 tickets.
the dance committee realizes that for every $1 increase in ticket price, they sell 10 fewer tickets. find the
maximum revenue and the ticket price that maximizes the revenue.
broo plsss heloo meeee
Answer:
$1440 max revenus$12 for a ticketStep-by-step explanation:
The quantity of tickets sold is presumed to be a linear function of the price. The revenue from sales will be the product of the number sold and their price.
__
quantityThe quantity sold is reduced by 10 when the price goes up 1, so the slope of the quantity curve is -10/1 = -10. The given point on the quantity curve is (p, q) = (4, 200). Using these values in the point-slope equation of a line, we find ...
q -200 = -10(p -4)
q = -10(p -4) +200 . . . . . add 200
revenueThen the revenue is ...
r(p) = pq
r(p) = p(-10(p -4) +200) = p(-10p +240)
r(p) = -10p(p -24) . . . . factored form
maximumThis equation describes a parabola with zeros at p=0 and p=24. The peak value of the revenue is on the axis of symmetry, halfway between the zeros. That is, the price p=12 will maximize revenue. At that price, the revenue is ...
r(12) = -10(12)(12 -24) = 10(144) = 1440
The maximum revenue is $1440 at a ticket price of $12.00.

A baseball player hits a pitched ball when it is 4 ft above the ground. The initial upward velocity is 80 ft/s. How
long will it take for the ball to hit the ground?
Answer:
t=+4.06
Step-by-step explanation:
when the baseball hits the ground, the height will be 0.
h=0we are given that h=−16t2+64t+4.
this means that the height is 0 when −16t2+64t+4=0.−16t2+64t+4=0divide both sides by 4:−4t2+16t+1=04=0−4t2+16t+1=0 can be solved using the quadratic formula:t=−b±√b2−4ac2a, where at2+bt+c=0.at2+bt+c=−4t2+16t+1a=−4,b=16,c=1t=−b+√b2−4ac2aor−b−√b2−4ac2a−b+√b2−4ac2a=−16+√272−8=−0.06..−b−√b2−4ac2a=−16−√272−8=4.06 (3s.f.)we have 2 values for t:−0.06 and 4.06.
since time cannot be negative, only the positive value can be taken.

Answer:
The power in repeated multiplication form is (-2)*(-2)*(-2)
The value of the power is -8
=====================================================
Reason:
Exponents represent repeated multiplication. The small number up top is the exponent that tells us how many copies of the base to multiply
In this case, the exponent 3 tells us we have 3 copies of "-2" multiplied together to get (-2)*(-2)*(-2)
This simplifies to -8

Use the layout of the parking lot to answer the questions. what is the total area available for cars to park? m2. if the parking spaces are compact, they have an area of 12.5 m2. how many compact parking spaces will fit in the lot? . if the parking spaces are not compact, they will be 3 meters by 5.5 meters. how many noncompact parking spaces will fit in the lot? .
The true statements are:
The total area available is 858 square metersThe number of compact parking space is 68 The number of non-compact parking space is 52The total area available for cars to parkFrom the complete question, we have the dimensions of the parking lot to be: 78 meters by 19 meters
Also, the dimension of the aisle is: 8 meters by 78 meters
The total parking area is the difference between the parking lot area and the aisle area
This gives
Parking Area = 78 * 19 - 8 * 78
Parking Area = 858
The total area available for cars to park is 858 square meters
The number of parking spaceThe number of parking lot is the quotient of the total parking area and the area of each compact
So, we have:
n = 858/12.5
n = 68.64
Remove the decimal
n = 68
Hence, the number of parking space is 68
The number of parking space for non-compact parking spaceThe number of parking lot is the quotient of the total parking area and the area of each non-compact space
So, we have:
n = 858/(5.5 * 3)
n = 52
Hence, the number of parking space is 52

If f(1) = 3 and f(n) = f(n - 1)2 + 5 then find the value of f(4).
Answer:
f(4) = 59
Step-by-step explanation:
Given:
f(1) = 3
f(n) = f(n-1)2 + 5
Idea:
We want to find the value of f(4), so let's substitute n with 4.
f(n) = f(n-1)2 + 5
f(4) = f(4-1)2 + 5
f(4) = f(3)2 + 5
We see that we have to evaluate f(3) before we can calculate f(4).
So let's try to calculate f(3).
f(3) = f(3-1)2 + 5
f(3) = f(2)2 + 5
Again we have to calculate f(2) before we can calculate f(3). So what do we do?
Calculations:
The best approach is to start from the bottom. First let calculate the value of f(2) and then f(3) and finally f(4).
f(1) = 3 (this was given)
f(2) = f(2-1)2 + 5
= f(1)2 + 5 (this time we know the value of f(1)!)
= 3 × 2 + 5
= 6 + 5
= 11
f(3) = f(3-1)2 + 5
= f(2)2 + 5 (we calculated f(2) in the previous step: f(2) = 11)
= 11 × 2 + 5
= 22 + 5
= 27
f(4) = f(4-1)2 + 5
= f(3)2 + 5
= 27 × 2 + 5
= 51 + 5
