Will a truck that is 10 feet wide carrying a load that reaches 12 feet above the ground clear the semielliptical arch on the one
beks73 [17]

Figure is missing, so i have attached it.

Answer:

it will clear the arch because the height of the archway of the bridge 5 feet from the center is approximately 12.76 ft

Step-by-step explanation:

The standard form of equation of an ellipse is;

x²/a² + y²/b² = 1

From the figure in the image attached, we can see that the radius is; a = 52/2 = 26 ft

While the value of b = 13 ft

Thus;

x²/26² + y²/13² = 1

x²/676 + y²/169 = 1

We want to find the height of the archway of the bridge 5 feet from the center.

Thus, we will plug in 5 for x to get;

5²/676 + y²/169 = 1

(25/676) + (y²/169) = 1

Multiply through by 676 to get;

25 + 4y² = 676

4y² = 676 - 25

y² = 651/4

y² = 162.75

y = 12.76 ft

Thus height of the truck is 12 ft and so it will clear the arch because the height of the archway of the bridge 5 feet from the center is approximately 12.76 ft

What is the complete factorization of the polynomial below
zepelin [54]

Answer:

B. (x+4)(x+i)(x-i)

Step-by-step explanation:

Let P(x)=x^3-4x^2+x-4

We can factor this polynomial by grouping:

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

We factor further to obtain:

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

P(x)=(x^2-\sqrt{-1}^2)(x-4)

We apply difference of two squares to get:

P(x)=(x-i)(x+i)(x-4)
