Answer:

A = 315

Step-by-step explanation:

Formula = (b * h) / 2

21 * 30 = 630

630 / 2 = 315

Aprils rainy day total would be different.

January would be 20, because 8 is bigger than 5.

February will be 20 as well, because 6 is bigger than 5.

And March would be 20 as well, because 7 is bigger than 5.

The only one that is not bigger than 5 is April, it is only 4. So it would be 10.

Which function is the inverse of f(x) = 2x + 3

Marizza181 [45]

Answer:

$\displaystyle f^{-1}(x)=\frac{x-3}{2}$

Step-by-step explanation:

<u>The Inverse of a Function</u>

The procedure to find the inverse of the function is:

* Write the function as a two-variable equation:

y = 2x + 3

* Solve the equation for x.

y - 3 = 2x

$\displaystyle x=\frac{y-3}{2}$

* Swap the variables:

$\displaystyle y=\frac{x-3}{2}$

Write back into function form. This is the inverse function:

$\mathbf{\displaystyle f^{-1}(x)=\frac{x-3}{2}}$

The solution to $\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)} = 1 + x^2$ is x = 1

<h3>How to solve the equation?</h3>

The equation is given as:

$\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)} = 1 + x^2$

Split the equation as follows:

$y\ =\ \left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}$

$y = 1 + x^2$

Next, we plot the graph of both equations (see attachment)

From the attached graph, the intersection point is (1, 2)

Remove the y value

x = 1

Hence, the solution to $\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)} = 1 + x^2$ is x = 1

Onondaga Electronics operates on a net-profit rate of 20% on its printer cables. If the markup is $8.95 and the overhead is $4.3

asambeis [7]

Answer:

The selling price be $79.56 .

Step-by-step explanation:

Let us assume that the cost price be x.

As given

If the markup is $8.95 and the overhead is $4.31 .

Selling price = Cost price + Markup price + Overhead price

= x + 8.95 + 4.31

= x + 13.26

Profit = Selling price - Cost price

= x + 13.26 - x

= $ 13.26

Formula

$Profit\ percentage = \frac{Profit\times 100}{Cost\ price}$

Putting the values in the above formula

$20= \frac{13.26\times 100}{x}$

$x= \frac{13.26\times 100}{20}$

$x= \frac{1326}{20}$

x = $ 66.3

Thus cost price be $66.3 .

Thus

Selling price = $66.3 + $13.26

= $ 79.56

Therefore the selling price be $79.56 .
