Answer:

[tex]5<t<6\\(5,6)[/tex]

Step-by-step explanation:

We know that the function of the height of a rocket after t seconds is:

[tex]h(t)=-9.8t^2+107.8t[/tex]

We want to find the interval of time such that the rocket is higher than 294 meters.

So, substitute 294 for h(t) and solve for t:

[tex]294=-9.8t^2+107.8t[/tex]

Just as it happens, everything is divisible by -9.8. So, divide everything by -9.8. This yields:

[tex]-30=t^2-11t[/tex]

Add 30 to both sides:

[tex]t^2-11t+30=0[/tex]

Factor. We can use -6 and -5. So:

[tex](t-6)(t-5)=0[/tex]

Zero Product Property:

[tex]t-6=0\text{ or } t-5=0[/tex]

Solve for each equation:

[tex]t=6\text{ or } t=5[/tex]

So, our answers are 5 seconds and 6 seconds.

Therefore, between the fifth and sixth second, the rocket is higher than 294 meters.

Note that at exactly the fifth and sixth second, our height is exactly 294 meters, not higher.

Therefore, we won't include 5 and 6 in our solution set.

As an inequality, this is:

[tex]5<t<6[/tex]

In interval notation, this is:

[tex](5,6)[/tex]

And we're done!

Answer:

6161 tiles

Step-by-step explanation:

1 m = 100 cm

2.02 m x 1.22 m = 246.44

=246.44 x 100

=24644 cm

2cm x 2cm = 4 cm

4cm= 1 tile

24644cm divided 4cm

=6161

=6161 to make border

12.5%

All you have to do to get the percentage is divide 3 by 24, which gives you .125

Then you multiply by 100 or, move decimal place two places to the right, which gives you 12.5 so 12.5%

Hope this helps

Answer: 12.5%

Step-by-step explanation:

3 / 24 = 0.125

Move the decimal point to the right 2 times and you get 12.5%

5 Because in the graph it shows

Because vertical is up and down so in the graph it shows that the purple section up and down is taking up 2 sections 10/2=5  and this means that one section is 5 units so the answer would be:

5 units

This is the graph of a quadratic function.

The y-intercept of the graph is the function value y = 0.

The x-intercepts of the graph (in order from least to greatest) are located at x = 0 and x = 6.

The greatest value of y is y = 9.

For x between x = 0 and x = 6, the function value y > 0.

In Mathematics, the graph of a quadratic function always form a parabolic curve or arc because it is u-shaped. Based on the graph of this quadratic function, we can logically deduce that the graph is a downward parabola because the coefficient of x² is negative and the value of "a" is greater than zero (0).

The y-intercept of the graph is represented by (0, 0) and the x-intercepts of the graph listed in order from least to greatest are located at the following points;

x = 0 ⇒ (0, 0)

x = 6 ⇒ (0, 6).

The greatest value or vertex (maximum value) of y is at y = 9. For x between x = 0 and x = 6, the function value y is always greater than 0.

Answer:

x = 45 miles

Step-by-step explanation:

We can use ratios to solve

2 gallons       3 gallons

--------------  = --------------

30 miles        x miles

Using cross products

2x = 3*30

2x = 90

Divide by 2

2x/2 = 90/2

x = 45 miles

Answer:

He can travel 45 miles with 3 gallons

Step-by-step explanation:

If he traveled 30 miles with 2 gallons then that would mean each gallon lasted 15 miles, 30/2=15, therefore if there were 3 gallons he would travel 45 miles, 45/3=15

The number of boxes that Amanda can cover with W square inches of wallpaper will be equal to W/2(lw + lh + wh).

Let's assume that Amanda wants to build n wooden storage boxes. All of these boxes are shaped like rectangular prisms, as shown in the image below.

She wants to cover all the sides of each box with special wallpaper. If she has a total of W square inches of wallpaper, we need to find out how many boxes she can cover. Let's solve this problem mathematically.

Mathematical Solution:

Each rectangular prism has six sides (faces). If we want to cover all the six sides of a rectangular prism with special wallpaper, we need to find the total surface area of that rectangular prism. Therefore, the surface area of each rectangular prism can be calculated by the formula:

Surface Area = 2lw + 2lh + 2wh,

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

We know that Amanda has W square inches of wallpaper to cover all the boxes. Therefore, the total surface area of n boxes will be:

n × Surface Area = W.

Substituting the value of the Surface Area, we have:

n × (2lw + 2lh + 2wh) = W

2n(lw + lh + wh) = W

n(lw + lh + wh) = W/2

n = W/2(lw + lh + wh).

Answer:

x = -10, y = -8

Step-by-step explanation:

We will use the method of elimination to find y.

Step 1: 5x - 8y = 14

          -

           5x - 7y = 6

Step 2:  0x - y = 8

Step 3: y = -8

Now, we have to substitute the y value into one of the original equations. In this case we will use the first equation which is 5x - 8y = 14.

5x - 8(-8) = 14

5x + 64 = 14

5x = - 50

x = -10

Just to make sure we have the right values, we will substitute both values into one of the equations.

5(-10) - 7(-8) = 6

-50 + 56 = 6

6 = 6           True

5(-10) - 8(-8) = 14

-50 + 64 = 14

14 = 14         True

Both of these values work, so they are the answers.

Answer:

see below

Step-by-step explanation:

We can use point slope form

y - y1 = m(x-x1)

where m is the slope and ( x1,y1) is a point on the line

y-12 = 3(x-12)

If we want it in slope intercept form

Distribute

y-12 = 3x-36

Add 12 to each side

y-12+12 = 3x-36+12

y = 3x-24

Answers:

x = 57

y = 86

z = 37

=================================================

Work Shown:

x+123 = 180 .... since x and 123 form a straight line

x = 180-123

x = 57

y = 86 since the y and 86 angles are vertical angles

-------

For any triangle, the three angles always add to 180. So,

x+y+z = 180

57+86+z = 180

143+z = 180

z = 180-143

z = 37

As a check,

x+y+z = 57+86+37 = 180

which confirms the value of z
