the answer is y=√r^2-x^2

To find the formula for y in the equation:
r^2=x^2+y^2
First thing we do is we must isolate the y variable
y^2=r^2-x^2
To simplify our answer is we will square root both of the sides of the equation,
y= \sqrt{r^2-x^2}
and this will be the formula for the resultant force for y.

Question 2: Please help I do not understand this question.
Svetradugi [14.3K]

The measurement of AB is 16.23.

Solution:

Given ACB is a right angled triangle.

AC = 10, ∠C = 90° and ∠A = 52°.

cos θ ≈ 0.616

Here AC is the base and AB is Hypotenuse.

To find the length of AB:

$\cos\theta=\frac{\text{Base}}{\text{Hypotenuse}}

$\cos 52^\circ=\frac{10}{AB}

$0.616=\frac{10}{AB}

Do cross multiplication, we get

$AB=\frac{10}{0.616}

AB = 16.23

Hence the measurement of AB is 16.23.

1)What are the first five terms of the sequence given by the formula an=4n+1 ?
koban [17]

Answer:1) c. 5,9,13,17,21

2)  a. a1=8, an=an-1 -2

Step-by-step explanation: 1) an=4n+1

    ⇒ a1=4×1+1=5

         a2=4×2+1=9

          a3=4×3+1=13

          a4=4×4+1=17

           a5=4×5+1=21

2) clearly a1=8 and then the terms of series are decreasing by 2

so, an=an-1 -2

Quadrilateral ABCD is a rectangle. If AE = 36 and CE = 2x - 4, find x.<br> B<br> E<br> А.<br> D
krek1111 [17]

The value of the x is 20 if the quadrilateral ABCD is a rectangle and  AE = 36 and CE = 2x - 4 because the diagonal of the rectangle bisect each other.

<h3>What is the area of the rectangle?</h3>

It is defined as the space occupied by the rectangle, which is planner 2-dimensional geometry.

The formula for finding the area of a rectangle is given by:

Area of rectangle = length × width

We know that the diagonal of the rectangle bisect each other.

AE = CE

36 = 2x - 4

2x = 40

x = 20

Thus, the value of the x is 20 if the quadrilateral ABCD is a rectangle and  AE = 36 and CE = 2x - 4 because the diagonal of the rectangle bisect each other.
