Answer:3.05 x10^9

Step-by-step explanation:

Answer:

Solution,

Let the hypotenuse of the right triangle be 'a' and its legs be 'b' and 'c'.

Here, a= 13, b = 4 and c=?

Using Pythagoras or Gogou theorem,

a² = b² +c²

or, 13² = 4² +c²

or, c² =153

or, c = 3√17 inch

-6

We assume "initial value" means the y-intercept is (0, 6). The rate of change is the "rise" divided by the "run" between the two points.

rise = -6 -6 = -12 . . . . difference of y-values

run = 2 -0 = 2 . . . . . . difference of corresponding x-values

rate of change = rise/run = -12/2 = -6

The rate of change of this line is -6.

The value of x in the given triangle is  [tex]1\frac{3}{5}[/tex]

Similar triangles have the same corresponding angle measures and proportional side lengths.

Given that, two triangles are similar, Δ MNO ~ Δ PQR,

According to definition of similar triangles,

PR/MO = QP/NM

x/4 = 2/5

x = 8/5

x = [tex]1\frac{3}{5}[/tex]

Hence, the value of x in the given triangle is  [tex]1\frac{3}{5}[/tex]

A statement that is true include the following: B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function f(x) over the interval [0, 1]:

a = 0; f(a) = 1

b = 1; f(b) = 6

By substituting the given parameters into the average rate of change formula, we have the following;

Average rate of change = (6 - 1)/(1 - 0)

Average rate of change = 5/1

Average rate of change = 5

For g(x), we have the following:

Average rate of change = (216 - 0)/(1 - 0)

Average rate of change = 216/1

Average rate of change = 216

Answer:

The earnings will double

Step-by-step explanation:

Step one:

given data

we are told that the sales person's earnings is 4% of the sales made.

given that the sales made is $37,000 worth of furnaces.

Step two:

we want to find 4% of $37,000

=4/100*37000

=0.04*37000

=1480

hence for $37,000 the earning will be $1480.

Now suppose sales is doubled that is 37000*2= 74000

we want to find 4% of $74,000

=4/100*74000

=0.04*74000

=2960.

the earnings is $2960.

So if sales doubles the earnings will double
