ANSWER

Step 3

EXPLANATION

The given polynomial expression is:

2 {p}^{2}  - 3p - 7 - (3 {p}^{2}  + p - 5)

Fatau correctly expanded the parenthesis in the first step.

2 {p}^{2}  - 3p - 7 - 3 {p}^{2}   -  p  +  5

Fatau also correctly grouped the like terms to obtain:

(2- 3) {p}^{2}   + (- 3 - 1)p  + (- 7 +  5)

Fatau committed a mistake at the third step.

Instead of obtaining,

- {p}^{2} - 4p   - 2

He mistakenly got:

{p}^{2}    - 2p  +2

Lostsunrise [7]
We have the following expression:
 (6.34 x 10 ^ -7) (4.5 x 10 ^ 3)
 The solution shown is:
 (6.34 x 10 ^ -7) (4.5 x 10 ^ 3)
 (6.34 x 4.5) (10 ^ -7 x 10 ^ 3)
 28.53 x 10 ^ -4
 -28.53 x 10 ^ 4
 -2.853 x 10 ^ 3
 The errors are:
 A. He changed the sign of the coefficient. A negative exponent does not affect the sign of a coefficient in scientific notation. The sign of the exponent determines the direction the decimal is moved in.
 D. He got the wrong value for the coefficients; 28.53 x 10^-4 is not possible. The coefficients in scientific notation are always greater than 1, but less than 10.

Find the value of each variable in the circle to the right. The dot represents the center of the circle.
MrMuchimi

9514 1404 393

Answer:

  a = 57.5

  b = 90

  c = 65

Step-by-step explanation:

The measure of an inscribed angle is half that of the arc it intercepts. The angle at 'a' intercepts an arc of 115°, so its measure is (115/2)° = 57.5°

__

The inscribed angle at 'b' is a semicircle, 180°, so the measure of 'b' is (180/2)° = 90°.

__

The arc 'c' is the remainder of a semicircle after 115° have been taken away. Its measure is 180° -115° = 65°.

  (a, b, c) = (57.5, 90, 65)

The sculpture consists of five identical prisms. JD says the surface area of the sculpture is 44 times the surface area of one p
larisa86 [58]
The complete question in the attached figure

we know that
(see the attached figure n 2 to understand the problem)
[the surface area of one prism]=2*[x*x]+2*[x*y]+2*[x*y]----> 2x²+4xy
[the surface area of the sculpture]=2*[5*x*y]+2*[3*x*x]+2*[3*x*y]--> 6x²+16xy

now
<span>JD says the surface area of the sculpture is 4 times the surface area of one prism
</span>[the surface area of the sculpture]=4*(2x²+4xy)---> 8x²+16xy

we compare the value that JD says with the real value
(8x²+16xy) > (6x²+16xy)
the value that JD says is <span>greater in comparison with the real value
</span>This is because <span>JD should also subtract the areas of eight hidden surfaces.

the answer is 
</span>JD should also subtract the areas of eight hidden surfaces<span>

</span>

50 points to the correct answer help ASAP
Colt1911 [192]

Answer:

V =785 in ^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We are given the radius =5 and the height = 10

V = (3.14) * (5)^2 *10

 = 3.14 *25*10

V =785 in ^3
