Suppose that a car rental agency charges a fixed amount per day plus an amount per mile for renting a car. Heidi rented a car one day and paid $52 for 180 miles. On another day she rented a car from the same agency and paid $77.50 for 350 miles. Find the linear function f(x) (where x is in miles and f(x) is in dollars) that the agency could use to determine its daily rental charges.
f(x) =
9514 1404 393
Answer:
f(x) = 0.15x +25
Step-by-step explanation:
We are given two points:
(x, y) = (180, 52) or (350, 77.50)
The slope is given by ...
m = (y2 -y1)/(x2 -x1)
m = (77.50 -52)/(350 -180) = 25.50/170 = 0.15
The y-intercept is given by ...
b = y -mx
b = 52 -0.15×180 = 25
Then the equation for the linear function is ...
f(x) = mx +b
f(x) = 0.15x +25
A homeowners’ association charges a $3.85 fee for each day your payment is late. If a bill was originally $98.75 and paid 13 days late, then how much is owed to the homeowners’ association?
Answer:
$148.80
Step-by-step explanation:
Find how much was charged extra with the late fee. Multiply 13 by 3.85:
13(3.85)
= 50.05
Add this to the original amount of the bill:
98.75 + 50.05
= 148.8
So, the amount owed is $148.80
Find the distance (-2,4) and (-5,-0)
Answer:
d=√65 units
Step-by-step explanation:
Using the distance formula :
d=√((−5)−(2))2+((0)−(4))2 units
d=√(−7)2+(−4)2 units
d=√49+16 units
d=√65 units

William is an electrician. He charges an initial fee of $44 per visit. If he charges $30 for every hour he works, which explicit
expression and recursive process can be used to find out how much he will charge for working n hours?
O A. Explicit Expression: 30n - 44
Recursive Process: To find out how much William will charge for working n hours, subtract $30 from how much he
charges for working n - 1 hours.
W = Wn-1 - $30, Wo = $44
OB. Explicit Expression: 30n +44
Recursive Process: To find out how much William will charge for working hours, add $30 to how much he charges for
working n - 1 hours.
W = Wn-1 + $30, Wo = $44
OC. Explicit Expression: 44n - 30
Recursive Process: To find out how much William will charge for working n hours, subtract $44 from how much he
charges for working n - 1 hours.
Wn = Wn-1 - $44, Wo = $30
OD. Explicit Expression: 44n+ 30
Recursive Process: To find out how much William will charge for working n hours, add $44 to how much he charges for
working n - 1 hours.
evaluate g(x)=x/x-3, if g(1/2)
Answer:
-1/5
Step-by-step explanation:
g(x) = x/(x-3)
Substituting x = 1/2 in g(x),
g(1/2) = 1/2/(1/2-3)
= 1/2/(1/2-6/2)
= 1/2/(-5/2)
= 1/2 ÷ - 5/2
= 1/2 x -2/5
= - 1/5

4x5-(22 - 2) =
(18= 3) + (32 - 7) =
Answer:
0 and 40
Step-by-step explanation:
First expression: 4*5 - (22 - 2). We must do work inside parentheses before any other work. This, we have 4*5 - (20), which simplifies to 20 - 20 = 0
Second expression: (18 - 3) + (32 - 7 becomes (15) + 25, or 40.

l[tex]\lim_{n \to \0} \frac{sin x}{x}[/tex]
1
Step-by-step explanation:
[tex]\displaystyle \lim_{x \to 0}\dfrac{\sin x}{x}[/tex]
Let
[tex]f(x)= \sin x[/tex]
[tex]g(x)=x[/tex]
We are going to use L'Hopital's Rule here that states
[tex]\displaystyle \lim_{x \to c}\dfrac{f(x)}{g(x)}=\lim_{x \to c}\dfrac{f'(x)}{g'(x)}[/tex]
We know that
[tex]f'(x) = \cos x[/tex] and [tex]g'(x)=1[/tex]
so
[tex]\displaystyle \lim_{x \to 0}\dfrac{\sin x}{x}=\lim_{x \to 0}\dfrac{\cos x}{1}=1[/tex]
Compute ∬_R〖(7xy-5-2y^2)dxdy〗 where the domain of integration R is bounded by the lines y=0, y=4-2x and y=2x^2
Attached you'll find the region of interest, which is captured by the set of points
R = {(x, y) | √(y/2) ≤ x ≤ (4 - y)/2 and 0 ≤ y ≤ 2}
Written in this way, it's convenient to integrate with the order dx dy (that is, with respect to x first). In particular, we have
[tex]\displaystyle\iint_R(7xy-5-2y^2)\,\mathrm dx\,\mathrm dy = \int_0^2 \int_{\sqrt{\frac y2}}^{\frac{4-y}2} (7xy-5-2y^2)\,\mathrm dx\,\mathrm dy[/tex]
[tex]\displaystyle = \int_0^2 \int_{\sqrt{\frac y2}}^{\frac{4-y}2} \left(\frac72 x^2y-5x-2xy^2\right)\bigg|_{\sqrt{\frac y2}}^{\frac{4-y}2}\,\mathrm dy[/tex]
[tex]=\displaystyle\int_0^2\left(\frac{15}8y^3-11y^2+\frac{33}2y-10 +\sqrt2 y^{\frac52}-\frac74y^2+\frac5{\sqrt2}y^{\frac12}\right)\,\mathrm dy[/tex]
[tex]=\displaystyle\left(\frac{15}{32}y^4+\frac{2\sqrt2}7y^{\frac72}-\frac{17}4y^3+\frac{33}4y^2+\frac{5\sqrt2}3y^{\frac32}-10y\right)\bigg|_0^2[/tex]

Suppose 2500 dollars is invested at 4% for 5 years. Find the account balance if it is
compounded daily, monthly, quarterly?
answer step by step
Answer:
Kindly check explanation
Step-by-step explanation:
Using the compound interest formula :
A = P(1 + r/n)^nt
A = final amount ; r = rate ; n = number of compounding times per period ; t = period ; P = principal
P = 2500 ; r = 4% = 0.04 ; t = 5 years
Daily compounding, n = 365
Yearly compounding, n = 1
Quarterly compounding, n = 4
Daily compounding :
A = 2500(1 + 0.04/365)^(5*365)
A = 2500(1.0001095)^1825
A = $3053.4734
Yearly :
A = 2500(1 + 0.04/1)^(5*1)
A = 2500(1.04)^5
A = $3041.6323
Quarterly:
A = 2500(1 + 0.04/4)^(5*4)
A = 2500(1.01)^20
A = $3050.4751

Cost for Lamps: 2 x 110 = $220
Cost for Switches: 5 x 41 = $205
Cost for Tubes: 6 x 135 = $810
Cost for Electric Wire: 230 x 2.50 = $575
Total cost: 2700 + 220 + 205 + 810 + 575 = $4510
Tax: Total cost x Tax rate = 4510 x 0.07 = $315.70

Use a net to find the surface area
Answer:
336 square inches
Step-by-step explanation:
Nets are the spreaded out version/outline of 3d figures. It shows the faces of the figure. The figure in this case is actually a triangular prism.
find the area of each shape in the net:
Triangle A (1/2 x base x height)
1/2 • 8 x 6 = 24 square inches
Rectangle B (length x width):
6 x 12 = 72 square inches
Rectangle C:
8 x 12 = 96 square inches
Rectangle D:
10 x 12 = 120 square inches
Triangle E:
1/2 x 6 x 8 = 24 square inches
Add up all the areas of all shapes:
24 + 24 + 120 + 72 + 96 = 336
Surface area is measured in square inches
(Inches in this case)

Point V is located at -16. Points W and X are each 7 units away from Point V. Where are W and X located?
Answer:
Location of W is - 23, location of X is - 9.
Step-by-step explanation:
location of V = - 16
Points W and X are each 7 units away from Point V.
Let the W is at left of V and X is right of V.
location of W = -16 - 7 = - 23
location of X = - 16 + 7 = - 9
