Find all roots of the polynomial function f(x) = 2x^4-x^3-13x^2+5x+15

Answers

Answer 1

Answer:

Roots are :  1, -7 and -7

Step-by-step explanation:

When we put x = -1 in F(x) it is equal to 0

Thus, (x + 1) is factor of given function.

When we divide F(x) by (x + 1) it gives the value (x² - 6x - 7)

factorizing the work  x² - 6x - 7 by middle term splitting.

> x² - 6x - 7 = x² - 7x + x - 7

>  x(x - 7) + 1(x - 7)

>  (x + 1) (x - 7)

then,  x³ - 5x² - 13x - 7 = (x + 1)(x + 1)(x - 7)

x = -1, -1, 7 the factor.

D and C is the answers.

Find the surface area of the square pyramid. Draw a net to find the area of the base and each face of the pyramid.

Answers

132! Read on for explanation..... So first step is to choose which to solve (either way works) for example let’s start with the base, the base is a square and a square will always have to the same measurements on each side so for the base you find your measurement, which is 6, so you multiply 6 by 6 to get 36, then you move on to the triangles, for the triangles it’s also asking the same thing as the base, but now it’s asking for the height and the base which the height is 8 and the base is 6, so you multiply those two numbers and get 48 BUT you also have to multiply 48 by 1/2 because the formula for a triangle is A = BH1/2 so 48 multiplied by 1/2 is 24 and instead of doing this for each side, you can simply multiply 24 by 4, because there are 4 triangles that make that shape complete, so 24 times 4 is 96, now you have add the sums, 96 plus 36 equals 132. and don’t forget to put 132 square ft.

For #1 no the doll wont fit in the box because there is 12 inches in a foot 12+12+8=32 so no.#2 Yes because half of of 85 is 42.5 and 85-17.6=67.4 and that wont make it half way.

Step-by-step explanation:

Number is no because there is more than 12 in. (Only 12in in a foot). And 2 is yes because half of 85 is 42.5 and there’s more room than that.
