what is the sum of three consecutive even numbers is 30?

Answers

8, 10, 12

A helpful equation:
x+x+1+x+2 = 30

Combine like terms
3x + 3 = 30

Subtract 3 from each side
3x = 27

Divide each side by to isolate x
x = 9

x = 9. However, 9 is not an even number. Let’s subtract 1 from 9 to get the first even number.

The first number is 8. The best two even numbers after 8 are 10 and 12.

8 + 10 + 12 = 30, thus this is the sequence.

Answer:

here:

you can make an equation

x + ( x + 2) + (x + 4) = 30

then by combining like items you get

3x + 6 = 30

then solve

3x = 30 - 6 ; then 3x = 24 , and x = 8

so the three numbers are 8 ; 10 and 12.

If r = 1 and θ = 4π/3 what is the approximate arc length

Answers

Answer: 4.189 units

Step-by-step explanation:

AP EX

As per linear equation, the required approximate arc length is 4.19 units.

What is a linear equation?

"An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line.

The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."

Given,  length of the radius (r) = 1 units

The value of the given angle(θ) = 4π/3 radian.

Therefore, the approximate arc length is

= length of the radius × value of the given angle

= r × θ

= 1 × 4π/3 units

= 4π/3 units

= 4.19 units

The required approximate arc length is 4.19 units.

A fastball is hit straight up over home plate. The ball's height, h (in feet), from the ground is modeled by ℎ = −16푡 ଶ+103푡+5 where t is time (in seconds).

Answers

Question:

A fastball is hit straight up over home plate. The ball's height, h (in feet), from the ground is modeled by h(t)=-16t^2+80t+5, where t is measured in seconds.  Write an equation to determine how long it will take for the ball to reach the ground.

Answer:

[tex]t = 5.0625[/tex]

Step-by-step explanation:

Given

[tex]h(t)=-16t^2+80t+5[/tex]

Required

Find t when the ball hits the ground

This implies that h(t) = 0

So, we have:

[tex]0=-16t^2+80t+5[/tex]

Reorder

[tex]-16t^2+80t+5 = 0[/tex]

Using quadratic formula, we have:

[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]

Where

[tex]a = -16[/tex]      [tex]b =80[/tex]      [tex]c = 5[/tex]

So, we have:

[tex]t = \frac{-80\±\sqrt{80^2 - 4*-16*5}}{2*-16}[/tex]

[tex]t = \frac{-80\±\sqrt{6400 +320}}{-32}[/tex]

[tex]t = \frac{-80\±\sqrt{6720}}{-32}[/tex]

[tex]t = \frac{-80\±82.0}{-32}[/tex]

This gives:

[tex]t = \frac{-80+82.0}{-32}[/tex] or [tex]t = \frac{-80-82.0}{-32}[/tex]

[tex]t = \frac{2}{-32}[/tex] or [tex]t = \frac{-162}{-32}[/tex]

[tex]t = -\frac{2}{32}[/tex] or [tex]t = \frac{162}{32}[/tex]

But time can not be negative.

So, we have:

[tex]t = \frac{162}{32}[/tex]

[tex]t = 5.0625[/tex]

Hence, time to hit the ground is 5.0625 seconds

Answers

Answer:

Step-by-step explanation:

Given equation is,

y = 3x² - 6x + 11

a). y = 3x² - 6x + 11

       = 3(x² - 2x) + 11

       = 3(x² -2x + 1 - 1) + 11

       = 3(x² - 2x + 1) - 3 + 11

       = 3(x - 1)² + 8

Comparing this equation with y = a(x - b)² + c

a = 3, b = 1 and c = 8

b). For minimum value of x,

    Since, vertex of the graph is given by (b, c),

    Minimum value of x will be,

    x = b

    x = 1

c). Vertex of the parabola → (b, c)

                                           → (1, 8)

    For y-intercept,

    By substituting x = 0 in the equation,

    y = 3(0 - 1)² + 8

    y = 11

Now we can sketch the graph by using the table of input - output values.

x         -2        -1           0            1             2          3

y        35        20         11           8            11         20

1.What was the error, expressed in inches?
2.What was the error, expressed as a percentage of the actual height?​

Answers

Percentage of error by Clare is estimated as 4.1667 %

Find the slope-intercept equation of the line.

Plz help last question
I need the equation plz

Answers

Answer:

[tex]y = 2x + 2[/tex]

Step-by-step explanation:

To find the slope you look at how much the line rises after going 1 unit to the right. In this equation it rises 2 after going over, or running, 1 unit to the right. So the rise over run is 2 over 1. It can be represented in a fraction 2/1. The slope is the rise over run, being 2.

The constant in the equation, or the y-intercept, is the point where the line intersects the y axis, the dark vertical line. You can count how many units it is from the origin where the 2 black lines intersect. The y-intercept in this is 2.

The slope is the number bedfore the x and the y intervept is the constant after the x.

Answer:

y = -2x + 2

Step-by-step explanation:

y=mx+b

find slope(m) first:

choose two points: (1,0), (0,2)

(y2-y1)/(x2-x1)
