Answer:

Malcom's family travel 15 miles per hour faster than Theo's

Step-by-step explanation:

See attachment for complete question

Given

Malcom's Family:

[tex]d = 65t[/tex]

To determine the equation of Theo's family, we refer to the attached graph.

From the graph:

[tex]t = 1; d = 50[/tex]

[tex]t = 2; d = 100[/tex]

First, we determine the slope, m:

[tex]m = \frac{d_2 - d_1}{t_2 - t_1}[/tex]

[tex]m = \frac{100 - 50}{2- 1}[/tex]

[tex]m = \frac{50}{1}[/tex]

[tex]m = 50[/tex]

Next, we determine equation for Theo's family using:

[tex]d - d_1 = m(t - t_1)[/tex]

[tex]d - 50 =50(t - 1)[/tex]

[tex]d - 50 =50t - 50[/tex]

Add 50 to both sides

[tex]d - 50 +50=50t - 50 + 50[/tex]

[tex]d =50t[/tex]

So, we have the following:

[tex]d = 65t[/tex] --- For Malcom's family

This implies that Malcom's family travel at 65 miles per hour

[tex]d =50t[/tex] --- For Theo's family

This implies that Theo's family travel at 50 miles per hour

The difference between this rates is:

[tex]Rate = 65t - 50t[/tex]

[tex]Rate = 15t[/tex]

Which implies that Malcom's family travel 15 miles per hour faster than Theo's

Step-by-step explanation:

The absolute value of a positive is that same number

For example the absolute value of 4 is 4

The absolute value of a negative is that same number without the negative sign.

For example, the absolute value of -4 is 4

Answer:

8x²-10x

Step-by-step explanation:

In Solving This Equation You Will Need To Follow This;

Original Equation:

2x(4x-5) {You will multiply 2x by the ones in the bracket which is the 4x and -5)

So 2x Multiplied by 4x is doing to give you 8x² we have 8x² because x multiplied by x becomes 2 that's why we have x² so 2x Multiplied by 4x is; 8x²

And 2x Multiplied by -5 is -10x because positive multiplied by negative is negative and when the number is with a variable and you want to multiply it by a natural number it is possible but you can't add a number with a variable to a natural number

So the final answer is; 8x²-10x

Step-by-step explanation:

Answer: 20%

Step-by-step explanation: The first step in finding how much the quantity decreased. We do a subtraction:

and now we must know how much percentage is 16 of 80, for this we divide:

and finally we convert this decimal value to a percentage multiplying by 100%

0.2(100%) = 20%

the quantity decreased by 20%

Answer:

The ball reaches its maximum height at 2.5 seconds

The maximum height is 100 feet

Step-by-step explanation:

Maximum Value of Functions

We use the derivative of a function to find its maximum or minimum value over a given interval.

Given a function y=f(x), the first derivative criterion establishes if x=a is such that:

f'(a)=0, and f''(a) < 0 then x=a is a maximum of f.

The height h in feet of a ball after t seconds is:

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

Find the first derivative:

[tex]h'(t)=-32t+80[/tex]

Equate to 0:

[tex]-32t+80=0[/tex]

Subtract 80:

[tex]-32t=-80[/tex]

Divide by -32:

[tex]t = -80 / (-32) = 2.5[/tex]

t=2.5 seconds

Find the second derivative:

h''(t)=-32

Since h''(t) is always negative, then

The ball reaches its maximum height at 2.5 seconds

To find the value of the maximum height, substitute t=2.5 into the function:

[tex]h(2.5)=-16(2.5)^2+80*2.5=-100+200 = 100[/tex]

The maximum height is 100 feet

Step-by-step explanation:

Answer:

37 and -18

Step-by-step explanation:

Let one number be x and other y

1 x + 1 y = 19 .............1

1 x -1 y = 55 .............2

Eliminate y

multiply (1)by 1

Multiply (2) by 1

1 x 1 y = 19

1 x + -1 y = 55

Add the two equations

2 x = 74

/ 2

x = 37

plug value of x in (1)

1 x + 1 y = 19

37 + 1 y = 19

1 y = 19 -37

1 y = -18

y = -18

37 and -18
