Answer:

0.1

Step-by-step explanation:

To find a geometric probability you would divide the area of the section wanted over the total area. In this case we would basically be dividing the area of the light grey box over the area of the dark grey rectangle(including where the light grey rectangle is). The area of a rectangle is the width times the length, so the area of the rectangles would be:

Light Grey:

4ft x 1.5ft = 6ft^2

Dark Grey:

12ft x 5ft = 60ft^2

Now we divide the areas:

6ft^2 / 60ft^2 = 0.1

Is (5, 10), (-8, 3), (-1, 7), (-5, 10) A Function ?

ankoles [38]

Answer:

Step-by-step explanation:

Notice that the inputs {5, -8, -1, -5} are all different. So we can immediately conclude that this is a function.

If the inputs were {5, -8, -1, 5}, this would not be a function, as the same input value (5) would result in two different outputs.

A farmer plows a corn field in the shape of a rectangle that has an area of 15840 square yards if the length of the field is 132

igomit [66]

Answer:

Width= 120

Step-by-step explanation:

We know that L*W= A

So lets put in the variables we know into the equation.

L= 132 yards

A= 15840

132 * W= 15840

All we need to do is divide 15840 by 132

15840/132= 120

W=120

When u = −2 5 , v = −5 2 , then the vectors in span{u, v} lie on a line through the origin. True or false?

Ira Lisetskai [31]

True.

The vectors are -25 in the left direction and;

-52 in the left direction

So they lie on the same line.

f(x) = 2x + 1

f(3) = 2*3 + 1 = 7

g(x) = x^2

g(7) = 7^2

g(7)= 49

f(g(x)) = 2(g(x) + 1

f(g(x)) = 2 x^2 + 1

f(g(3) = 2* 3^2 + 1

f(g(3) = 19

g(f(x)) = (f(x))^2

g(f(x)) = (2x + 1)^2

g(f(3)) = (2*3 + 1)^2 = (6 + 1)^2 = 49

f(g(x)) = 2*g(x) + 1

f(g(x)) = 2*x^2 + 1

f(g(3)) = 2*3^2 + 1

f(g(3)) = 2 * 9 + 1

f(g(3)) = 18 + 1

f(g(3) = 19

f(g(x)) = 2(g(x)) + 1

f(g(x)) = 2*x^2 + 1
