use tangent.

from the corner y look for the opposite and adjacent sides to your angle.

the opposite side from corner y is 13

the adjacent side from the corner is 4

tanY = 13/4

Y = inverse tangent of 13/4

If the area of a rectangle is 12cm2 what could its length be and its width?
lawyer [7]
Hello, 

We know that th formula for the area of a rectangle is: A=b*h
Now, the problem in this excercise is that there is no restriction on the values that b and h can take, so, they can take any value provided that it meets:  b*h=12 cm^{2}
for example:
lenght=  \frac{12}{3}cm \,\,\,\,\,\,and\,\,\,\,width= 3 cm \\  \\ A=\frac{12}{3}cm*3cm \\ A=12 cm^{2}

But if they can only take intenger values, what we have to do is to descompose 12, and then we can analyze the possible solutions.

12   |  2
  6   |  2
  3   |  3
  1

12= 2 *2*3

first option:
12=4*3

Answer: lenght= 4cm   and   width= 3cm  or vice versa

second option:
12=2*6

Answer: lenght= 6cm   and   width= 2cm  <span>or vice versa</span>

Calculate the average rate of change for the function
mezya [45]

slope = m = \cfrac{rise}{run} \implies \cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby \begin{array}{llll} average~rate\\ of~change \end{array}\\\\[-0.35em] \rule{34em}{0.25pt}\\\\ f(x)= 2(x-2)^2+1\qquad \begin{cases} x_1=-2\\ x_2=4 \end{cases}\implies \cfrac{f(4)-f(-2)}{4-(-2)} \\\\\\ \cfrac{[2(4-2)^2+1]~~ - ~~[2(-2-2)^2+1]}{4+2}\implies \cfrac{[9]~~ - ~~[33]}{6}\implies \cfrac{-24}{6}\implies -4

Write out the first 5 outpouts of g(x)=2^x starting with G(1). If only you knew that the value of g(15) how would you determine
gtnhenbr [62]

The first 5 outputs are:

\begin{array}{c|c}x&2^x\\1&2\\2&4\\3&8\\4&16\\5&32\end{array}

As you can see, the outputs keep doubling each time we increment x by 1.

This can be written formally, observing that if you know the value of 2^x, the next value will be

2^{x+1}=2^x\cdot 2

So, again, we've shown that the next value is twice the previous one, so you have

g(16)=2g(15)

Hamish and hairy work as plumbers. Harry earns a dollar more than 5/4 The amount Hamish orange per hour. The amount Harry earns
Mnenie [13.5K]

Answer:

Harry earns 26 and Hamish earns 20

Step-by-step explanation:

The computation of the amount earned by each one of them is shown below:

Let us assume the hairy be Y

And, the Hamish be M

It is given that Harry earns a dollar i.e more than 5/4

And, it is $2 less than  7/5

So, the equation would be

y = 1.25m + 1  ...........................(i)

And,

y= 1.4m -2  .............................(ii)

Now equal both the equations

1.25m + 1 = 1.4m - 2

3 = 0.15m

So, m = 20

Now put the values of m in any of the above equation to find out the value of Y

Y = 1.25m + 1

= 1.25 (20) + 1

= 26
