I need the answer for Number six

Answers

Step-by-step explanation:

Although I can't give you a written answer, here's how you do it.

For y = -x + 7, we know 7 is our y coordinate, so place a point on 7 on the y axis.

-x is equal to -1/1, so when graphing the line, go down 1 over 1 and place your point. Continue until you reach the edge of the graph.

For 5x + 5y = 10, subtract 5x from the left side of the equation. This will leave you with:

5y = -5x + 10. Divide every term by 5, leaving you with y = -x + 2. Your teacher may want you to phrase this as y = 2 - x. 2 is your y coordinate, and once again -x is -1/1. Start at 2 and go down 1 over 1 on the graph.

How do you find the time an object is at a certain height algebraically? For example, given the function h(t) = -16t2 +32t represents the height of a ball thrown from ground level. How do you find the time when the ball is 10 feet above the ground? Explain in your own words.

Answers

9514 1404 393

Explanation:

To find the time, substitute the height for h(t), then solve the quadratic equation for t.

___

To solve the equation, you subtract the height from both sides, then use the quadratic formula. In generic terms, this looks like ...

-16t^2 +32t -h = 0

t = (-32±√(32^2 -4(-16)(-h)))/(2(-16))

t = (-32 ± √(1024-64h))/-32

t = 1 ± √(1 -h/16)

For h = 10 ft, the times are ...

t = 1 ± √(3/8) ≈ {0.388, 1.612} . . . . seconds

Using the quadratic formula is not the only way to solve a quadratic. One of my favorite methods is using a graphing calculator.

What is the slope-intercept form?

In Mathematics, the slope-intercept form of a line can be calculated by using this linear equation:

y = mx + c

Where: m represents the slope. x and y are the data points.

c represents the y-intercept.

Next, we have to determine the slope of the data points in this table as follows;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (44.50 - 32.00)/(3 - 2)

Slope, m = 12.5/1

Slope, m = 12.5.

At point (2, 32.00), a linear equation of this line in slope-intercept form as follows:

y - y₁ = m(x - x₁)

y - 32.00 = 12.5(x - 2)

y - 32.00 = 12.5x - 25

y = 12.5x - 25 + 32.00

y = 12.5x + 7

Use slope formula to find the slope:

8-5.5/2-1 = 2.5

therefore the M (slope) is 2.5

Answer:

y = 2.5x + 3

Step-by-step explanation:

y2 - y1/x2 - x1 = slope

5.5 - 3 = 2.5

2 - 1 = 1

2.5/1 = 2.5

8 = 2.5(2) +b

8 = 5 + b = 3

Choose the correct definition of volume. A the amount of space a 2-dimensional object takes up B.distance from one point to another C. the amount of space a 3-dimensional object takes up D. the distance from the bottom to the top of an object

Answers

Answer:

The answer is C

Step-by-step explanation:

Well I took a lesson on volume before and volume and In math, volume can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object. Here, the blocks and books take up space.

The correct definition of volume is,

⇒ The amount of space a 3-dimensional object takes up.

Option C is true.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

To find the definition of volume.

We know that;

Volume is known as the space occupied within the boundaries of an object in 3D- space. It is also known as the capacity of the object.

Thus, The correct definition of volume is,

⇒ The amount of space a 3-dimensional object takes up.

Option C is true.

Find angle RST
Please help

Answers

Answer:

Step-by-step explanation:

so because the triangle going through the center it classifieds as a right triangle which makes angle SRT = 90 degree

three angle of a triangle add up to 180

so we have SRT + RTS + RST = 180

we have SRT

=> 90 + RTS + RST = 180

=> 90 + (3x -25) + (x - 1 ) = 180

=> 90 + 4x -26 = 180

=> 64 + 4x = 180

=> 4x = 116

=> x = 29

now u have x , just plug in and solve

Gina uses the function LaTeX: k\left(h\right)\:=\:\sqrt{4h\:-\:12}k ( h ) = 4 h − 12 to model the height of a kite based on the amount of string released when the kite is flown. The variable h represents the height of the kite in feet and k(h) represents the amount of string released in feet. How how high was the kite when Gina released 20 feet of string?

Answers

Answer:

68 feet

Step-by-step explanation:

Gina uses the function to model the height of a kite based on the amount of string released when the kite is flown:

k(h) = 4h − 12

Where

h represents the height of the kite in feet

k(h) represents the amount of string released in feet.

We need to find the height when Gina released 20 feet of string.

Put h = 20 in the above formula.

k(20) = 4(20) − 12

= 68 feet

So, the required height is 68 feet.
