Factor x2 – 3x – 28.

Mathematics
1 answer:
wariber [46]1 year ago
3 0

Values needed to complete the X diagram are:

On top -28, On the bottom: -3 and On the sides: -7 and 4.

<h3>What do you mean by factorization?</h3>

An algebraic expression is factorised when it is written as the product of its factors.

The given equation is :

F(x) = x²-3x-28

finding factors,

=  x²-7x+4x-28

= x(x-7) +4(x-7)

= (x-7)(x+4)

Given general equation is ax²+bx+c,

on comparing with  x²-3x-28

a = 1

b = -3

c = -28

ac = 1*(-28) = -28

What is 70/360 in percentage​
defon

Answer:

About 19.45%

Step-by-step explanation:

First set the fraction equal to x over 100 ———- (70/360)=(x/100)

cross multiply———- 70 * 100 = 7000            360 * x = 360x

solve for x —————- 7000=360x

                                   7000/360= 19.44444444

Round ——- x=19.45

OR

Divide fraction ———— 70/360 = 0.1944444444

Next, convert to percentage by moving decimal 2 places to the right ——

019.44444444

Round ————- = 19.45

The volume of a sphere is a function of its​ radius, V=4/3 πr^3 Evaluate the function for the volume of a volleyball with radius
il63 [147K]

The volume of a volleyball with radius 11.1 cm is 5731.025 cubic centimeter

<h3><u>Solution:</u></h3>

Given that volume of a sphere is a function of its​ radius

V=\frac{4}{3} \pi r^{3}

Radius = 11.1 cm

<em><u>To find: volume of a volleyball</u></em>

Since volleyball is generally of spherical shape, we can use volume of sphere formula

\text {volume of sphere }=\frac{4}{3} \pi r^{3}

Where "r" is the radius of sphere and \pi is a constant which has value 3.14

<em><u>Substituting the given radius r = 11.1 cm</u></em>

\text {volume of sphere }=\frac{4}{3} \times \frac{22}{7} \times 11.1^{3}

\text {volume of sphere }=\frac{88}{21} \times 1367.631

volume of sphere = 5731.025 cubic centimeter

Thus the volume of volleyball is 5731.025 cubic centimeter
