PLS HELP MEEE PICTURE BELOW

Mathematics
1 answer:
Leviafan [203]2 years ago
5 0

Answer:

h = 3.6

Step-by-step explanation:

This is just substituting in for variables and solving for x. The hard part is knowing the formula.

R = h((a+b)/2) where a and b are the 2 different bases, h is the height or latitude, and R is the area of a trapezoid, is the formula.

Given that R = 8.1, a = 1 and b = 3.5, we can substitute these equations in the formula.

(8.1) = h(((1) + (3.5)) / 2)

= h((4.5) / 2)

= h(2.25)

8.1/2.25 = h

3.6 = h

Find the derivative of f(x)=2arcsin(x-1)

Since \dfrac{\mathrm d}{\mathrm dx}\arcsin x=\dfrac1{\sqrt{1-x^2}, you have

\displaystyle\frac{\mathrm d}{\mathrm dx}2\arcsin(x-1)=2\frac{\mathrm d}{\mathrm dx}\arcsin(x-1)=2\frac{\dfrac{\mathrm d}{\mathrm dx}(x-1)}{\sqrt{1-(x-1)^2}=\frac2{\sqrt{2x-x^2}}

PLEASE HELP FAST READ EVERYTHING CORRECTLY ITS ASKING FOR GRAPHING ILL MARK BRIANLIST FOR EVERYTHING!
vaieri [72.5K]

Answer:

They can`t cross because the slopes are the same.

Since the first equation isn`t simplified, I`ll simplify it.

-x + 4y = -8

4y = x - 8

<u>y = x - 2</u>

After both are simplified, both slopes will be positive 1x. That means the lines are parallel and never cross. I`m sorry if this wasn`t much help, but that is the only answer I can think of. If there is not other option than placing a real answer, than I wouldn`t know how to solve this, sorry.

​Aki's Bicycle Designs has determined that when x hundred bicycles are​ built, the average cost per bicycle is given by​ C(x)=0.
Semmy [17]

Answer:

<u>maximum of 2 bicycle</u>

Step-by-step explanation:

Given the average cost per bicycle modeled by the equation

C(x) = 0.5x^2-1.5x+4.83

C(x) is in hundreds of dollars

x is number of bicycle

The number of bicycle that will minimize the cost occurs when dC/dx = 0

dC/dx = 2(0.5)x - 1.5

dC/dx = x - 1.5

Since dC/dx = 0

0 = x - 1.5

x = 0+1.5x = 1.5

Hence the shop should  buy <u>maximum of 2 bicycle</u> to minimize the cost
