Answer:

y = 2x + 75

when x = 0, y = 75

when x = 11, y = 97

when x = 20.25, y = 115.5

when x = 58, y = 191

Step-by-step explanation:

To get the total number of pages she has read, y, after x minutes have elapsed. We will have to go by general form of equation which says

y = mx + b where m is the rate of change or simply the slope, which is 2 pages/minute. and y-intercept will be the number pages she has already read. Our equation will now be y = 2x + 75

The next step is to start substituting the numbers in to the equation

When X = 0

y = 2(0) + 75 = 75

when x = 11

y = 2(11) + 75 = 97

when x = 20.25

y = 2(20.25) + 75 = 115.5

when x = 58

y = 2(58) + 75 = 191

when x = 0, y = 75

when x = 11, y = 97

when x = 20.25, y = 115.5

when x = 58, y = 191

Is a + b rational or irrational

Crank

Answer and fdaStep-by-step explanation:::

The answer depends on the numbers that are inputted for a and b.

If the numbers that are inputted for both a and b are rational, then a + b would be rational.

If the numbers that are inputted for both a and b are irrational, then a + b would be irrational.

If one of the variables is rational and the other is irrational, then a + b would be irrational.

Radius question <br><br> * answers listed on pic but I just need a step by step explanation *

Rama09 [41]

Step-by-step explanation:

Let A(x) be the area function of given rectangle.

Radius of circle = 7x

Therefore, length of rectangle = 14x

Width of rectangle = 7x

$\therefore \: A(x) =l\times w \\ = 14x \times {(7x)} \\ =98x^2 \\ \huge \red{ \boxed{ \therefore \: A(x) =98 {x}^{2} }}$

Let P(x) be the Perimeter function of given rectangle.

$P(x) =2(l + w) \\= 2(14x + 7x)\\=2\times 21x\\= 42x\\\huge \red{ \boxed{ \therefore \:P(x)= 42x}}$

What is the answer to this question I can’t work it out Ni=n02(yi-yo)/t2

Changing the subject of an equation involves solving for another variable in the equation

The equation of t is $t=\frac{\sqrt{y_i-y_o}}{N}$

<h3>How to change the subject of the equation</h3>

The equation is given as:

$N=\sqrt[2]{\frac{y_i-y_o}{t^2}}$

Rewrite the equation as:

$N=\sqrt{\frac{y_i-y_o}{t^2}}$

Evaluate the square root of t^2

$N=\frac{\sqrt{y_i-y_o}}{t}$

Multiply both sides by t

$Nt=\sqrt{y_i-y_o}$

Make t the subject, in the above equation

$t=\frac{\sqrt{y_i-y_o}}{N}$

Hence, the equation of t is $t=\frac{\sqrt{y_i-y_o}}{N}$
