Tom sold magazines for 4 days last week. The table above gives the total number of magazines Tom had
sold for the week at the end of each of the 4 days. Which of the following best models the relationship
between the total number M of magazines Tom sold and the number x of days selling?
O M(x)=x+4
O M(x)= 1.5x +4
20 M(x)= 4x + 4
> M(x)= 6x+4
Answers
Answer:
C. [tex] M(x) = 4x + 4 [/tex]
Step-by-step explanation:
Find the rate of change/slope (m) using two pairs (1, 8) and (2, 12):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 8}{2 - 1} = \frac{4}{1} = 4 [/tex]
(Note: M(x) = y)
Find y-intercept (b) by substituting x = 1, M(x) = 8, and m = 4 in M(x) = mx + b.
Thus:
8 = (4)(1) + b
8 = 4 + b
Subtract 4 from each side
8 - 4 = b
4 = b
b = 4
substitute m = 4, and b = 4 in M(x) = mx + b, to get the equation that models the relationship.
The equation would be:
✅ [tex] M(x) = 4x + 4 [/tex]

If (x + 7) is a factor of f(x), what is the value of f(-7)?
Answers
Answer:
The answer is 0.
Step-by-step explanation:
Simply plug in -7 for x as they want to see what the value of the function is when x=-7.
You can then just add -7 and 7.
7 + -7 = 0
So the answer is 0
Calculate the force output by the larger piston of a hydraulic lift when a force of 800 N is exerted on the smaller piston. The areas of the two pistons are 20 cm2 and 500 cm2.
Answers
answer:
F2= 5kNstep by step explanation
Note the second diameter was used as 50cm and not 500cm
given
F1=800N
D1=20cm
A1=πD1^2/4
=3.142*20^2/4
=314.2cm^2
D2= 50cm
A2=πD2^2/4
=3.142*50^2/4
=1963.75cm^2
The pressure applied on the smaller relative to the bigger end is expressed as
F1/A1=F2/A2
substitute we have
800/314.2=F2/1963.75
cross multiply we have
F2=800*1963.75/314.2
F2=1571000/314.2
F2=5000N
F2=5kN
The larger Force is 5kN

Shannon's new car sold for $28,000. Her online research indicates that the car will depreciate exponentially at a rate of 5 ¼ % per year. Write the exponential depreciation formula for Shannon's car.
Answers
Answer:
P = 28,000(0.945)^y
where P is the price of the car after y years of purchase
Step-by-step explanation:
The rate of decrease is 5 1/4 % per year
This is same as 5.5% (5.5/100 = 0.055) per year
The exponential equation will be ;
P = 28,000( 1 - 0.055)^y
P = 28,000(0.945)^y
where y is the number of years after the year of purchase

The gallons of gasoline used on a car trip varies directly as the number of miles driven. If 25 gallons of gasoline has been used after driving 700 miles,how many gallons of gasoline would be used after driving 1000 miles? Round your answer to the nearest tenth
Answers
Answer:
35.7 gallons
Step-by-step explanation:
Given that:
Distance traveled = 700 miles
Gasoline used = 25 gallons
The gallons of gasoline used are directly proportional to the number of miles traveled.
To find the gallons of gasoline to be used after driving 1000 miles, we can use the unitary method in which we first of all find, how much gallons of gasoline would be used for 1 mile and then multiply the value with 1000 to find the answer.
700 miles are traveled by gallons of gasoline = 25
1 mile is traveled by gallons of gasoline = [tex]\frac{25}{700}[/tex]
1000 miles are traveled by gallons of gasoline = [tex]\frac{25}{700}\times 1000 = \bold{35.7\ gallons}[/tex]

Find the measure of the complementary angle for letter S, 14 degrees.
Answers
Answer:
The complementary angle for letter S will be: 76°
Step-by-step explanation:
As we know that two angles will be complementary if their measures add to 90°.
Given the angle of letter S = 14°
Let suppose the other measuring complementary angle is m∠A.
so the equation becomes
So
14° + m∠A = 90°
m∠A = 90° - 14°
= 76°
Therefore, the complementary angle for letter S will be: 76°
