x^2 = 15^2 + 36^2

X^2 = 225 + 1296

X^2 = 1521

x = sqrt(1521)

x =39

This is a right triangle, so we can use the Pythagorean Theorem to find x; the Pythagorean Theorem is a^2 + b^2 = c^2, where c is the hypotenuse. In this case, x is the hypotenuse. Let's set up an equation:

15^2 + 36^2 = c^2
225 + 1296 = c^2
1521 = c^2
39 = c

Answer:
x = 39

Question 13 (4 points) (05.03) Which of the following statements best describes the graph of -5x + 2y = 1? (4 points)

alexandr1967 [171]

Answer:

C) straight line through (1, 3) ... (-3, -7)

Step-by-step explanation:

The linear equation will describe a straight line. The slope and general location of the line on a graph can be estimated from its x- and y-intercepts.

<h3>intercepts</h3>

The x-intercept is the value of x that satisfies the equation when y=0.

-5x +2·0 = 1

x = -1/5 . . . . . . divide by the coefficient of x

The y-intercept is the value of y that satisfies the equation when x=0.

-5·0 +2y = 1

y = 1/2 . . . . . . divide by the coefficient of y

<h3>nature of the graph</h3>

The intercept values mean the line crosses the positive y-axis and the negative x-axis. It will have a positive slope. Points on the line that have integer x- and y-coordinates will have coordinates that have the same sign.

Of the offered answer choices, A and B are eliminated because the graph is <em>not a curve</em>. D is eliminated because the suggested points have coordinates with <em>opposite signs</em>. The correct choice is C:

It is a straight line joining the points (1, 3), (3, 8), and (-3, -7)

Help!!!How does the slope of g(x) compare to the slope of f(x)?

attashe74 [19]

we know that

The formula to calculate the slope m between two points is equal to

$m=\frac{(y2-y1)}{(x2-x1)}$

Step $1$

<u>Find the slope of the function f(x)</u>

Let

$A( 0,-2)\\B(1,0)$

substitute the values in the formula above

$m=\frac{(0+2)}{(1-0)}$

$m=2$

<u>the slope of the function f(x) is $m=2$ </u>

Step $2$

<u>Find the slope of the function g(x)</u>

Let

$C( -4,0)\\D(0,2)$

substitute the values in the formula above

$m=\frac{(2-0)}{(0+4)}$

$m=\frac{2}{4}$

$m=\frac{1}{2}$

the slope of the function g(x) is $m=\frac{1}{2}$

therefore

slope f(x) > slope g(x)

slope g(x) < slope f(x)

<u>the answer is the option </u>

B.The slope of g(x) is less than the slope of f(x).

The packaging lists a model airplane’s length as 10.5 in. It also gives the scale as 1:83. What is the length of the actual airp

Kruka [31]

Since the scale is 1:83, the real airplane is 83 times longer than the model airplane.

real length = 10.5 in * 83 = 871.5 in

Now we convert 871.5 in into ft.
1 ft = 12 in, so 1 in = 1/12 ft
We divide the number of inches by 12 to find the number of feet.

871.5 in = 871.5/12 ft = 72.625 ft

What does inversely proportional mean

Assoli18 [71]

If one value is inversely proportional to another then it is written using the proportionality symbol in a different way. Inverse proportion occurs when one value increases and the other decreases. For example, more workers on a job would reduce the time to complete the task. They are inversely proportional.
