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.
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
Find the measure of the complementary angle for letter S, 14 degrees.
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°

If (x + 7) is a factor of f(x), what is the value of f(-7)?
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

A university wants to build a new residence hall with dorm rooms. The length is 3x+1 ft and the width is x^2-1 ft. If the university wants each room to have 195ft^2 of living space, what should be the dimensions of each dorm room? ["living space confuses me because idk if it's volume or bottom surface area]
Length of room, l = 3x + 1 ft.
Breadth of room, b = x² -1 ft.
Now, it is given that university wants each room to have 195 ft² of living space.
So,
[tex]lb = A\\\\(x^2-1)(3x+1)=195\\\\3x^3+x^2-6x-1=195\\\\3x^3+x^2-6x-196=0[/tex]
So, above equation has two complex root and one real root i.e x = 4.08 ft .
Therefore, Length of room is 13.24 ft and breadth is 15.65 ft.
Hence, this is the required solution.

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
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]

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.
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
H(x) =2x+3 James brought a plant that was 3 inches tall. Each week the plant grew 2 inches. The function h(x) = 2x + 3 describes the height of the plant after x weeks. Which is the reasonable domain for this function?
Answer:
For 6 weeks, the height will be 15 inchesStep-by-step explanation:
Step one:
given data
the initial height of plant= 3inches
growth in inches per week =2inches per wee
Step two:
for x number of weeks, the height is expressed as
[tex]h(x) = 2x + 3[/tex]
With the given growth function, we can estimate the height of the plant after any number of weeks, say x=6, that is 6 weeks, the height will be
substitute x=6 in the growth function
[tex]h(x) = 2(6)+ 3\\\\h(x) = 12 + 3\\\\h(x) = 15 inches[/tex]
Is this correct??????????
