Select the correct constant rate of change for each table of data.

Answer:

Equation A has the larger y intercept.

Equation A has a y-intercept of 2

Equation B has a y intercept of -5

Step-by-step explanation:

Equation A is in the slope intercept form of a line.

y = mx + b.  The number in the b place is the y-intercept.

y = 5x + 2.  The 2 is in the intercept place so the y-intercept is 2.

Equation B is written in the standard form of a line.

5x + 4y  = -20

If I let x = 0, I can solve for the y intercept.

5(0) + 4y = -20

4y = -20  Divide both sides by 4

y = -5

This would be point (0,-5).  The y-intercept is always boing to be when x = 0.

The expression 23 x 10 to the third power has a value of 23000

The mathematical statement is given as

"What's is 23x10 to the third power"

This can be represented as

23 x 10 to the third power

The third power represents the power of 3

i.e A number to the exponent of 3

So, we have

23 x 10 to the third power = 23 x 10^3

Express 10^3 as 1000

23 x 10 to the third power = 23 x 1000

Evaluate the product

23 x 10 to the third power = 23000

Hence, the solution is 23000

The proper rounding of 190.4592785 to the nearest tenth gives 190.4.

Look at the next place value to the right to round a number to the closest tenth (the hundredths). Simply eliminate all the numbers to the right if the number is 4 or fewer.

Add one to the digit in the tenth place if the number is five or above, and then eliminate all the digits to the right.

To round digits to the tenth means after the decimal there is only one number. It is tenth place.

190.4592785 = 190.4

Therefore, the nearest round to the tenth is 190.4.

Hope this helps!

The solution of the equation for v is [tex]v = \sqrt{\frac{2KE}{m}}[/tex]

This involves isolating a variable in an equation different from the initial isolated variable

The equation is given as

KE = 1/2mv²

Divide both sides of the equation by m

So, we have the following equation

KE/m = 1/2mv²/m

Multiply both sides of the equation by 2

So, we have the following equation

2KE/m = 2 * 1/2mv²/m

Evaluate the quotients and the products

2KE/m = v²

Take the square roots

[tex]v = \sqrt{\frac{2KE}{m}}[/tex]

By the above computation, we changed the subject of the formula in KE = 1/2mv² from KE to v.

This implies that solving for v is a concept of subject of formula

Hence, the solution is [tex]v = \sqrt{\frac{2KE}{m}}[/tex]

Answer:

Step-by-step explanation:

This question tests on the concept of slope or gradient of a line.

We know that the equation, m, for a slope =

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

We can identify 2 points from the question as (x1, y1) and (x2, y2) to solve for the gradient, and therefore they are:

(x1,y1) as (-3,-7.5)

(x2,y2) as (2,-4)

Now we can substitute these values in to solve for the slope.

[tex] \frac{ - 4 - ( - \frac{7}{2})}{2-(-3)} \\ = \frac{ - 4 + frac{7}{2}}{5} \\ = \frac{-0.5}{5} \\ = - \frac{1}{ 10} \\ = -0.1[/tex]

The equation of slope-intercept form is  y = mx - m.

What is slope-intercept form?

from the graph points are  ( 1 , 1 )

So,  x = 1 & y = 1

Equation is y = mx + c

put the value (x, y)

         1 = m * 1 + c

         1 = m + c

          c = - m

  y = mx - m

The gravity is working. Energy-based items are affected by gravity. The vertical motion model, h = -16t2 + vt + s, where v is the initial velocity in feet/second and s is the height in feet, to calculate the maximum height of the ball.

The distance traveled in flight increases with release level. This is because the projectile will stay in the air longer if it is launched higher. The projectile will be under the influence of the horizontal component longer.

The beginning vertical velocity determines the maximum height. Increasing the launch angle raises the maximum height because steeper launch angles have a larger vertical velocity component.

Greater maximum height is associated with greater launch angles.

Greater relative projection height results in longer flight time, which increases horizontal displacement when projection speed is constant.

Given,

Here we have the graph.

And we need to find the the best estimate for the solution to the system.

While we looking into the graph we have identified, that both line will intersect at some point.

Basically the solution of the graph is also the same point.

So, when we look into the graph we have identified that the value of y at the intersecting point is 0. Because the line will pass the x - axis line.

So, here we have to identify the x value of the solution,

this one the value of x is greater than or equal to 0.5. Because the line will be pass in between 0 and 1.

The equation of the parabola that has a vertex at (-5,3) and passes through (-4,2) is y = [tex]-x^2-10x-22[/tex]

The vertex of the parabola = (-5,3)

Passing through the point = (-4,2)

The equation of the parabola in the vertex form y = [tex]a(x-h)^2+k[/tex]

(h,k) is the vertex of the parabola

h = -5

k = 3

Substitute the values in the equation

y = [tex]a(x+5)^2+3[/tex]

Here the parabola is passing through the point (-4,2)

Substitute this value in the equation and find the value of a

2 = [tex]a(-4+5)^2+3[/tex]

2 = a×1+3

2 = a+3

a = 2-3

a = -1

Then

y = [tex]-1(x+5)^2+3[/tex]

y = [tex]-1(x^2+10x+25)+3[/tex]

y = [tex]-x^2-10x-25+3[/tex]

The given scales which measure the attitude of a person is an ordinal scale such as a Likert scale

An ordinal scale provides a report of the rating, order or rank of a data without stating the extent of variation between the categories.

There are many types of rating scales used to directly measure the attitude of a person towards a subject matter.

The Likert scale which is the most widely used rating scale, when applied, consists of a five or seven point scale, that empowers the subject of the survey to express how much they agree (or disagree) with a specified statement.

Generally, five options, graded from, mild to extreme are provided so that the survey subject can indicate (express), their strength of how much they agree with or feel about the statement or question

-1/2 is the slope of the line that passes through the points (12,-1) and (-2,6).

Slope is simply expressed as change in y over the change in x.

The slope formula is expressed as;

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given the data in the question;

Point 1( 12, -1 )

Point 2( -2, 6 )

To determine the slope of the line, plug the given coordinates into the slope formula above.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( 6 - (-1) )/( -2 - 12 )

Slope m = ( 6 + 1) )/( -2 - 12 )

Slope m = ( 7 ) )/( -14)

Slope m = -7/14

Slope m = -1/2

Therefore, the slope of the line is -1/2.
