In order to answer the question, we simply substitute the value of p and q to the given expression and solve. We do as follows:

<span>P^2q^2+pq–q^3–p^3 
</span>0.5^2(-0.5)^2+0.5(-0.5)–(-0.5)^3–(0.5)^3
-3/16 or -0.1875

Hope this answers the question. Have a nice day.

Alice is building a caterpillar habitat for some caterpillars
Alenkinab [10]

Answer:

The total amount of screen needed is 22 ft^2

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The surface area of a rectangular prism is equal to

SA=2B+Ph

where

B is the area of the base

P is the perimeter of the base

h is the height of the rectangular prism

<em>Find the area of the base B</em>

B=(3)(1)=3\ ft^2

<em>Find the perimeter of the base P</em>

P=2(3+1)=8\ ft

The height of the prism h is

h=2\ ft

substitute the values

SA=2(3)+(8)(2)

SA=22\ ft^2

The total amount of screen needed is 22 ft^2

Help please on this math problem: The prices of backpacks at a store are 22, 16, 39, 35, 19, 34, 20, and 26. Find the Mean Absol
Ivanshal [37]
Answer: 7.22
(note: this is a result after rounding. The result before rounding was 7.21875)

========================================================

Explanation:

Given Set of Values = {22, 16, 39, 35, 19, 34, 20, 26}

Add up the values: 22+16+39+35+19+34+20+26 = 211
Divide that sum by 8 as there are 8 values: 211/8 = 26.375

The mean is 26.375

Now subtract the mean from each data value. Apply the absolute value to ensure the difference is never negative

|22 - 26.375| = 4.375
|16 - 26.375| = 10.375
|39 - 26.375| = 12.625
|35 - 26.375| = 8.625
|19 - 26.375| = 7.375
|34 - 26.375| = 7.625
|20 - 26.375| = 6.375
|26 - 26.375| = 0.375

Add up those results
4.375+10.375+12.625+8.625+7.375+7.625+6.375+0.375 = 57.75
Then divide by 8 
57.75/8 = 7.21875

The mean absolute deviation of the prices is 7.21875
Rounded to two decimal places, it is 7.22
Since we're talking about money, it makes sense to round to the nearest penny.

Fiona is pricing two bicycles one is 175 with 10% and the other is 225 with 35% off which bicycle can she afford if she has 150
Gekata [30.6K]
If the one for $175 is 10% off, that means Fiana pays 90% of the price

175 * 0.9 = $157.50

It is too expensive because 157.50 is more than the 150 Fiana has.

The second bike for $225 is 35% off which means Fiana pays 65% of the price.

225 * 0.65 = $146.25

She CAN afford the bike for $225

Which is the equation of the given line? (-10,-7) (3,-7)
Vladimir [108]

Answer:  y=-7

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

Find the slope with this formula:

m=\frac{y_2-y_1}{x_2-x_1}

Given the points (-10,-7) (3,-7), substitute values into the formula. Then:

m=\frac{-7-(-7)}{-10-3}\\\\m=\frac{0}{-13}\\\\m=0

Substitute the slope and any point into  y=mx+b and solve for "b":

-7=0x+b\\b=-7

Then, substituting "m" and "b" into the equation  y=mx+b, you get that the equation of this line is:

 y=0x-7

 y=-7

Factorize 3x²-11x-20​
lbvjy [14]

1) Split the second term in 3x^{2} -11x-20 into two terms.

3x^{2} +4x-15x-20

2) Factor out common terms in the first two terms, then in the last two terms.

x(3x+4)-5(3x+4)

3) Factor out the common term 3x+4.

(3x+4)(x-5)
