Answer:

x=54

Step-by-step explanation:

These angles are vertical angles, which means they are equal

2x+2 = 3x-52

Subtract 2x from each side

2x+2-2x = 3x-52-2x

2 =x-52

Add 52 to each side

2+52 = x-52

54=x

The diagonal of a rectangular swimming pool measures 29 yards. If the length of the pool is 25 yards, which measurement is close

nirvana33 [79]

Answer:

Width of the pool = 15 yards

Step-by-step explanation:

Given that:

Length of diagonal of swimming pool = 29 yards

Length of the pool = 25 yards

Let,

w be the width.

This will form a right angled triangle where the diagonal will be hypotenuse.

Using Pythagorean theorem;

$(25)^2+(w)^2 = (29)^2\\625+w^2=841\\w^2= 841 - 625\\w^2 = 216$

Taking square root on both sides

$\sqrt{w^2}=\sqrt{216}\\w=14.70$

Rounding off to nearest whole number

w = 15 yards

Hence,

Width of the pool = 15 yards

Given the graph of f(x), find each of the following:

Y_Kistochka [10]

The value of the function at x = -1, 0, 1, 2, and 3 will be -4, 3, 2, -1, and 0, respectively.

<h3>What is a function?</h3>

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

From the graph of f(x), then the value of the function at x = -1, 0, 1, 2, and 3 will be given as,

x f(x) Feedback

-1 -4 Point is in the fourth quadrant

0 3 Point is in the y-axis

1 2 Point is in the first quadrant

2 -1 Point is in the second quadrant

3 0 Point is in the x-axis

More about the function link is given below.
