Answer:

x(x - 2)(x + 5)
x = 0, x = 2, x = -5

Step-by-step explanation:

x^3 + 3x^2 - 10x

~Factor

x(x - 2)(x + 5)

Solve for the zero.

x(x - 2)(x + 5) = 0

We know that; x = 0, x - 2 = 0, and x + 5 = 0

x = 0

x - 2 = 0

x = 2

x + 5 = 0

x = -5

Best of Luck!

Here we are provided with an polynomial of degree 3 and we have to factorise it first and then we have to compute it's zeroes.

Given Polynomial:

x³ + 3x² - 10x

Taking common x from all the 3 terms,

➝ x(x² + 3x - 10)

Factorising through Middle term factorisation,

➝ x(x² + 5x - 2x - 10)

➝ x{x(x + 5) - 2(x + 5)}

➝ x(x - 2)(x + 5)

Hence, Factorised !!

Now equating to 0 to find the zeroes of the poly.

➝ x(x - 2)(x + 5) = 0

That means,

x = 0
x - 2 = 0
x + 5 = 0

So, the zeroes of the polynomial is 0, 2 or -5

And we are done....

Determine the degree of the given polynomial x^2 ( 1 - x^3)

Ray Of Light [21]

Answer:

$\huge\boxed{\bf\:5}$

Step-by-step explanation:

Polynomial = $x^{2} (1 - x^{3})$ .

Before determining the degree of the polynomial, let's open the parentheses using the distributive property .

$x^{2} (1 - x^{3})\\=\underline {x^{2} - x^{5}}$

Degree is the highest exponential power in a polynomial .

So, the degree of the given polynomial is 5.

I need help with this question! will give thanks :)))

topjm [15]

Answer:

2 $\sqrt{13}$

Step-by-step explanation:

Use the distance formula and plug in the values

d=(3−(−3))2+(2−6)2√

d=(6)2+(−4)2√

d=36+16√

d= $\sqrt{52}$

d= 2 $\sqrt{13}$

(05.04 MC) An image of a rectangular pyramid is shown below: A right rectangular pyramid is shown. Part A: A cross section of th

sleet_krkn [62]

Answer:

Part a) Rectangle

Part b) Triangle

Step-by-step explanation:

Part A) A cross section of the rectangular pyramid is cut with a plane parallel to the base. What is the name of the shape created by the cross section?

we know that

When a geometric plane slices any right pyramid so that the cut is parallel to the plane of the base, the cross section will have the same shape (but not the same size) as the base, So, in the case of a right rectangular pyramid, the cross section is a rectangle

Part b) If a cross section of the rectangular pyramid is cut perpendicular to the base, passing through the top vertex, what would be the shape of the resulting cross section?

we know that

Cross sections perpendicular to the base and through the vertex will be triangles

cupoosta [38]

Answer:

NPV = $ 17,200,000

Step-by-step explanation:

Total expenditures = $ 11,000,000

Net cash inflow = $ 3,000,000 per year

total duration of cash inflow = 9 years

Thus, total cash inflow = $ 3,000,000 per year × 9 years = $ 27,000,000

salvage value = $ 1.2 million = $ 1,200,000

NPV = Salvage value + total cash flow - Expenditures

on substituting the values, we get

NPV = $ 1,200,000 + $ 27,000,000 - $ 11,000,000

NPV = $ 17,200,000

Find the value of x round to the nearest tenth

Leto [7]

Answer:

58.6

Step-by-step explanation:

Use the formula $c=\sqrt{a^{2}+b^{2}$

solving for x (b)

$b=\sqrt{c^{2}-a^{2}$ = $\sqrt{61^{2}-17^{2}$ ≈58.58327

and 58.58327 rounds to 58.6
