Answer:

The question does not have value of height (in the image)

the barn in shape of a cuboid with a half cylinder.

volume of barn = volume of cuboid + volume of cylinder/2

\text{Volume}_{barn}=lbh+\frac{\pi r^2 l}{2}

here,

2r = b

b=6 m

l=10 m

so, 2r=6. thus, r=3,

\text{Volume}_{barn}=lbh+\frac{\pi r^2 l}{2} \\ \text{Volume}_{barn}= 60\timesh+\pi \times9 \times 5

which approximately,

141.3+60h

for storing all of the hay

141.3+60h≥600

h≥7.644

so..

check if h is less than 7.644, he would not be able to store all of the barn.

If both the zeroes of a polynomial x2+4x+2p are real and equal then find the value of p.
creativ13 [48]

Answer:

p = 2

Step-by-step explanation:

If both zeroes at equal, they must be the negative half of the second term. As this term is 4, -\frac{4}{2} =-2. This means that each of the zeroes must be -2. This means that the polynomial must be  (x+2)^2

This simplifies to x^2+4x+4

From the intial problem, we can set up an equation and solve for p. 2p=4\\\\p=2

Factor the polynomial expression 4x3 - 4.
Sloan [31]
<h3>Answer:  4(x - 1)(x^2 + x + 1)</h3>

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

Work Shown:

4x^3 - 4

4(x^3 - 1)

4(x - 1)(x^2 + x + 1)

In the last step, I used the difference of cubes factoring formula which is

a^3 - b^3 = (a - b)(a^2 + ab + b^2)

Solve the system of linear equations below: <br> 2x + 5y = 34<br> x + 2y = 14
7nadin3 [17]
X + 2y = 14
-2y

x = -2y + 14

substitute x into the first equation

2 (-2y + 14) + 5y = 34
-4y + 28 + 5y = 34

simplify your y variable

y + 28 = 34

subtract 28 to find out what y equals

y = 6

now substitute y into the equation to find out what x equals

x + 2(6) = 14
x + 12 = 14

subtract 12 to get x

x = 2

now replace your values into an ordered pair, which is the solution
