Answers

Answer:

x = 38.05

Step-by-step explanation:

Using the Pythagoras theorem to find x

x is the hypotenuse

The other sides are opposite and adjacent

x² = 30²+25²

x² = 900+625

x² = 1525

x = √1525

x = 39.05

Here are the steps along with the answer.

Find the solution(s) to the system of equations. Select all that apply.
y=x²-4
y=-x-2

Answers

A and C as they both cross over eachother which determines the answer

The solution will be the intersection points thus options A (1,-3) and B (-2,0) will be correct.

What is a graph?

The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.

For example plot of y = x³ ,y = sinx.

The solution will be the intersection points of both functions.

At the intersection point,

x² - 4 = -x - 2

x² + x - 2 = 0

x² + 2x - x - 2 = 0

x(x + 2) - (x + 2) = 0

(x - 1)(x + 2) = 0

x = 1,-2

At x = 1

y = -1 - 2 = -3 so first intersection is (1,-3)

At x = -2

y = -(-2) - 2 = 0 so second intersection is (-2,0)

Hence "The solution of the given system of equations is (1,-3) and (-2,0)".

This Week's High Temperatures (°F)
29, 38, 45, 31, 50, 58, 62

Answers

Answer:

44.7

Step-by-step explanation:

Find the mean of the data set shown below. Round to the nearest tenth, if necessary.

This Week's High Temperatures (°F)

29, 38, 45, 31, 50, 58, 62

The formula for the Mean of a given set of data is

= Sum of terms/ Number of terms

Number of terms = 7

Hence,

Mean = 29+ 38+ 45+ 31+ 50+ 58+ 62/7

Mean = 44.714285714286

Approximately to the nearest tenth= 44.7

JKLM is a rectangle. if JL = 4x - 12 and MK = x, what is the value of x? what is the length of each diagonal?

Answers

Answer:

x = 4

The diagonals are both 4

Step-by-step explanation:

The fact that the two sides have no letter in common indicates that they are opposite each other or a diagonal. In this case the length is a diagonal. Diagonals in a rectangle are equal.

4x - 12 = x Add 12 to both sides

4x - 12 + 12 = x + 12 Subtract x from each side

4x - x = 12

3x = 12 Divide by 3

3x/3 = 12/3

x = 4

One of the diagonals = 4 because it is x.

A triangle equals 180° so set up the equation as
58+73+12x+1=180
132+12x=180 (I got 132 by adding 58,73,1)
Subtract 132 from both sides
You should get 12x=48
Divide both sides by 12
X=4

The sum of all the angles in a triangle is 180°.

(12x + 1) + 58° + 73° = 180°

12x + 132° = 180°

12x = 180° - 132°

x = 48°/12

x = 4°
