So 4x^2+-2x+-6 then multiply by 5 would be the Area of the entire rectangle using the formula A=bh

You'll get 4x^2  −  2x  −  6

a = 5

b = 4x² - 2x - 6

The area is:

a · b = 5(4x² - 2x - 6) = 20x² - 10x - 30

Or you can add areas of shapes:

- blue: 5 · 4x² = 20x²

- pink: 5 · (-2x) = -10x

- green: 5 · (-6) = -30 <- a little strange, the length of a side shouldn't be negative

Sum of those areas is the area of entire rectangle: 20x² - 10x - 30

But the first option is easier here.

the uniform distribution over the interval 8.5 to 11.5 gallons per minute. Find the probability that between 9.0 gallons and 10.
Tema [17]

Answer: 1/3

Step-by-step explanation:

Here is the complete question:

machine is set to pump cleanser into a process at the rate of 9 gallons per minute. Upon inspection, it is learned that the machine actually pumps cleanser at a rate described by the uniform distribution over the interval 8.5 to 11.5 gallons per minute. Find the probability that between 9.0 gallons and 10.0 gallons are pumped during a randomly selected minute.

The Probability of the above question will be calculated as:

= (10-9) / (11.5 - 8.5)

= 1/3

The above is the easier way to solve this

Hi I have no idea how to do this question :)
erik [133]

Answer:

A. 36

Step-by-step explanation:

Because the two angles at the bottom of both the triangles are congruent, the two triangles are similar. Therefore, the corresponding side lengths of the triangles must be proportional to each other

if the area of a triangle is hb/2,

(with h=length of height, b=length of base)

the height of the first triangle is:

25 = 10h/2

50 = 10h

h=5

you can write ratios representing the proportions of the two triangles:

5/x = 10/12 (with x=height of second triangle)

x=6

then find the area of the second triangle with the height (6) and base (12)

(6*12)/2 = 36
