Answer:

C. a=12ft, b=12ft

Step-by-step explanation:

This is a 45*-45*-90* triangle

"a" and "b" are the same

and the hypotenuse (which is 12 square roots of 2) is square root of 2 times as long as each leg.

so the answer must be:

a = 12ft, b = 12ft

Two cities Asheville and Boulder are 2.5 inches apart on a map. A third city well spring is located exactly halfway between Asheville and Boulder. If the scale is 0.5 inches = 15 miles find the actual distance from wellspring to Boulder

Answers

Answer:

75miles

Step-by-step explanation:

Let A be the location of Asheville, B be the location of Boulder and W be the location of wellspring.

If well spring is located exactly halfway between Asheville and Boulder, then;

AW + WB = AB

If Asheville and Boulder are 2.5 inches apart on a map, then AB = 2.5 inches

The actual distance from wellspring to Boulder is WB

Since W is the midpoint of A and B, then AW = WB. The equation becomes;

WB + WB = AB

2WB = AB

WB = AB.2

WB = 2.5/2

WB = 1.25 inches

Hence the distance from wellspring to Boulder is 1.25inches.

Since  0.5 inches = 15 miles on the map,

1.25inches = x

Cross multiply;

0.5x = 15 * 1.25

0.5x = 18.75

x = 18.75/1.25

x = 75miles

Hence the actual distance from wellspring to Boulder is 75miles

The monthly gross receipts for the ABC Copy Creation house amounted to $20,834.34. Unfortunately, the expenses amounted to $18,750.91, but this did give the owner of the company some profit. What was the profit for the month?

Answers

Given :

The monthly gross receipts for the ABC Copy Creation house amounted to $20,834.34.

The expenses amounted to $18,750.91.

To Find :

What was the profit for the month.

Solution :

We know, profit is given by :

Profit, P = Monthly income - Expenses

P = $( 20,834.34 - 18,750.91 )

P =  $2083.43

Therefore, the profit for the month is $2083.43 .

A hot air balloon in flight begins to ascend at a steady rate. After 1.5 minutes, the balloon is at an altitude of 2150 feet. After 3 minutes, it is at an altitude of 2330 feet. Use an equation in point-slope form to determine the altitude the balloon will reach after 5 minutes.

Answers

Answer: hope it helps

Step-by-step explanation:The balloon will not reach 2,500 feet after 4 minutes.

Step-by-step explanation:

The equation of the line in the point-slope form is

A hot air balloon in flight begins to ascend at a steady rate of 120 feet per minute, then the slope is

After  minutes, the balloon is at an altitude of  feet. This means, the line passes through the point (1.5, 2,150).

Substitute the slope and point coordinates into the equation:

We know that after 3 minutes, the balloon is at an altitude of 2,330 feet. Check this:

Now, find the height after 4 minutes:

Thus, the balloon will reach only 2,450 feet after 4 minutes.

What is the average rate of change of the function
f(x) = 2x + 8
over the interval [2, 6)?

Answers

The average rate of change of the function f(x) over the interval [tex][2, 6][/tex] is 2.

Important information:

The function is [tex]f(x)=2x+8[/tex].The given interval is [2,6].Average rate of change:

The average rate of change of the function f(x) over the given interval [tex][a,b][/tex] is:

[tex]m=\dfrac{f(b)-f(a)}{b-a}[/tex]

Using the above formula, we get

[tex]m=\dfrac{f(6)-f(2)}{6-2}[/tex]

[tex]m=\dfrac{(2(6)+8)-(2(2)+8)}{4}[/tex]

[tex]m=\dfrac{12+8-4-8}{4}[/tex]

[tex]m=\dfrac{8}{4}[/tex]

[tex]m=2[/tex]

Thus, the average rate of change of the function f(x) over the interval [tex][2, 6][/tex] is 2.
