The scatter plot shows the profit by the month for a new company during its first year of operation. Which equation most closely models the line of best fit for the scatter plot? A) y = 5x B) y = 2.5x C) y = 5x + 1000 D) y = 2.5x + 1000
Answers
The equation most closely models the line of best fit for the scatter plot is y = 2.5x
Equation of a lineA line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b
m is the slopeb is the intercept
Using the coordinate points on the line (3, 5000) and (9, 20000)
Get the slope
Slope = 20000-5000/9-3
Slope = 15000/6 = 2500
Determine the y-intercept
5000 = 2500(3) + b
b = 5000 - 7500
b = -2500
Determine the equation
y = 2.5x - 2.5
Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x

If you buy three of the ABC bonds with $10 commission for each, how much will it cost?
a. $3142.50
b
$1047.50
c. $3172.50
d. $1077.50
Answers
Answer:
The computation shows that the cost of each bond is A. $3142.50
How to solve the cost?
From the complete information given, the price of the bond is given as $2856.80 each.
Therefore, with the commission, the price will be:
= $2856.80 + (10% × $2856.80)
= $2856.80 + $285.68
= $3142.50
In conclusion, the cost of each bond is $3142.50.

If f(1) = 3 and f(n) = f(n - 1)2 + 5 then find the value of f(4).
Answers
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

=====================================================
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)

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
Answers
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.
