Which set of parametric equations represents the following function y=square root of x+3
Irina18 [472]
The given equation is:

y= \sqrt{x+3}

We have to find, which of the given set of parametric equations given in the options, result in the above equation:

The correct answer would be option A.

The equations in option A are:

x(t) = 5t \\ 
y(t)= \sqrt{5t+3}

From first equation we can see that 5t is equal to x. Using the value of 5th in second equation, we get the equation as:

y= \sqrt{x+3}

Therefore, the correct answer is option A

What is the slope of the line that passes through the points (-3, -9)(−3,−9) and (22, -4) ?(22,−4)? Write your answer in simples
bezimeni [28]

Answer:

1/5

Step-by-step explanation:

Equation: \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

Points: (-3, -9) and (22, -4)

y_{2} is the second y point that shows up on the question, basically go by order. So it's -4

y_{1} is -9, because again, in order of which coordinates pop-up first in the question

x_{2} is 22, x_{1} is -3

Now input into the equation, to make it easier we'll split the fraction into 2 equations:

\frac{y_{2} - y_{1}}{x_{2} - x_{1}} = y_{2} - y_{1} and x_{2} - x_{1}, we'll put them back in a fraction later

y_{2} - y_{1} = -4 - (-9) = -4 + 9 = 5

x_{2} - x_{1} = 22 - (-3) = 22 + 3 = 25

now put it in the fraction, remember y on top x on the bottom:

5/25, simplify, 1/5

Answer:

The area of circle = πR ^2

And diameter = 7 units

By interchanging d in R =d/2 = R =7/2 = 3.5

Step-by-step explanation:

<h3>πR ^2 =3.14 x (3.5)^2</h3><h3> =3.14 x 3.5 x 3.5</h3><h3> =38.465 (unit)^2 <em><u>Answer</u></em></h3>
