Ƒ(x) = x2 + 3x - 10. Determine the zeros of the equation.
7nadin3 [17]
I am assuming the equation is as follows
f(x) = x^2 + 3x - 10

Since the constant 10 is -10 this tells us we are going to have different signs + - after you have factored the equation.

First thing first. Think of two numbers that will give you the product(The answer after two numbers are multiplied) of -10 and the sum(Two numbers added together) of +3. I get the 3 from the 3x.

We know 5 x -2 = -10 and the sum 5 + -2 =  +3
With that said, we found our two factors
(x + 5)(x - 2)

Now write them as zeros and solve for x
x + 5 = 0
x = -5

x - 2 = 0
x = 2

So the zeros are -5 and 2.

Both circle A and circle B have a central angle measuring 135°. The ratio of the radius of circle A to the radius of circle B is
Darina [25.2K]
7/8π

The circles have the same central angle measures; therefore, the ratio of the intercepted arcs is the same as the ratio of the radii.

4/7 = 1/2π over x

x = 7/8π

Introduction to area of a piecewise rectangular figure
stich3 [128]

Given:

The piecewise rectangular figure.

To find:

The area of the piecewise rectangular figure.

Solution:

Draw a line and divide the given figure in two parts (a) and (b) as shown in the below figure.

Figure (a) is a rectangle of length 5 yd and width 3 yd. So, the area of the rectangle is:

Area=length\times width

A_a=5\times 3

A_a=15

Figure (b) is a square of edge 2 yd. So, the area of the square is:

Area=(edge)^2

A_b=(2)^2

A_b=4

The area of the given figure is:

A=A_a+A_b

A=15+4

A=19

Therefore, the area of the given figure is 19 square yd.
