Alright, I'm pretty sure I can help.

Let's look at the first answer choice.

7 - 2 (m + 1)

Distribute -2 and add the remaining numbers to get the total for that answer choice.

7 - 2m - 2

Simplify. You get 5 - 2m.

Looks like we found the answer on the first choice!

The Final Answer is 7 - 2 (m + 1)

Find the largest possible revenue from the demand equation "Q= -2p + 1000
Mariana [72]
Revenue=quantity x price= (-2p+1000) (p)= -2p^2+1000p
The maximum revenue will occur when the first derivative is zero so when 2(-2p)+1000=0;p=250
Which generates 125,000 in revenue
Try prices of 245 and 255 and you will see they both are less than 250 thereby proving the max revenue is 250

If the slope of line p is 1/5 and the slope of line q is -5 then what is true about lines p and q? (assume lines p and q are cop
vladimir2022 [97]

For this case, we have to define perpendicular lines:

m1 * m2 = -1

We have then:

m1 = \frac {1} {5}\\m2 = -5

Then, according to the definition we have:

(\frac {1} {5}) (- 5) = \frac {-5} {5} = -1

We observe that the definition is fulfilled, therefore, the lines are perpendicular.

Answer:

b. they are perpendicular

Find the volume of a pyramid with a square base, where the side length of the base is
vivado [14]

Answer:

Volume of the pyramid =  927.72 m² (Approx)

Step-by-step explanation:

Given:

Length of base = 16.6 m

Height of the pyramid = 10.1 m

Find:

Volume of the pyramid = ?

Computation:

Area of the square base = Side²

Area of the square base = (16.6)²

Area of the square base = 275.56 m²

Volume\ of\ the\ pyramid = \frac{1}{3}(Area\ of\ base)(Height)\\\\Volume\ of\ the\ pyramid = \frac{1}{3}(275.56)(10.1)\\\\Volume\ of\ the\ pyramid = 927.7186

Volume of the pyramid =  927.72 m² (Approx)

Given the trinomial, what is the value of the coefficient 'B' in the factored form?. . 2x^2 + 14xy - 36y^2 = 2(x + By)(x - 2y).
soldi70 [24.7K]
The value of the coefficient B is 9.

2(x+By)(x-2y)
=2(x^2 -2xy +Bxy -2By^2)
=2x^2 -4xy + 2Bxy - 4By^2

The original form is 2x^2 + 14xy - 36y^2

-36y^2 = -4By^2
B= 9
-4xy +2Bxy= 14xy
xy(-4 +2B)= 14xy
-4 + 2B = 14
2B = 18
B=9
