A 30 foot ladder is set against the side of a house so that it reaches up 24 feet. If Alexander grabs the ladder at its base and

pulls it 10 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 14 ft.) Round to the nearest tenth of a foot.

Answer:

The answer would be 10.8

Step-by-step explanation:

By finding the missing base side on the original triangle (which is 18), we add 10 to that number to find the base side on the second triangle. We can then use the equation "sin(21.04) = x/30" to find the missing length side (21.04 is the degree measurement).

Hope this helps :)

The graph below represents which system of inequalities?
attashe74 [19]

Answer:

y ≤ 2x -2 Option C.

Step-by-step explanation:

Equation of the dotted line which passes through (3,0) and (0,8) will be

y = mx+C

m = \frac{y-y'}{x-x'}=\frac{3-0}{0-3} = -1

and C = 3

So equation will be y = x + 3

But shaded blue part is above the dotted line so inequality will be y> -x +3

Equation of the second solid line which passes through ( 0,-2) and (1,0) will be

y = mx + C

m = \frac{y-y'}{x-x'} = \frac{0+2}{1-0} = 2

and C = -2

So equation of the line will be y = 2x - 2

But shaded yellow part is below the solid line.

So inequality will be

y ≤ 2x -2

Option C. is the answer.

I don't understand calculus at all bruh :/. I figured out some of this but I don't know it the answer is 0 or 2. Whoever figures
Lady_Fox [76]

Answer:

-2

Step-by-step explanation:

This one you just plug in 32 because there is no denominator of 0.

So as x goes to 32, y would go to 2 because 5rt32 = 2

<u>EDIT</u>

My bad, i didn't see it as -32. the answer would be -2 though I believe bc

5rt-32 = -2

To rent a moving truck there is a fee of $150 and each mile you drive costs an extra $1.75 per mile, where R(x) is the total cos
abruzzese [7]

Answer:

$318

Step-by-step explanation:

First, we want to set up an equation to solve this problem by using the information given to us. We're asked for the total cost, so we want one side of the equation to be R(x)=. Then, we know that the initial cost is $150, no matter how many miles we drive. We are also told that each mile is $1.75.

R(x)=150+1.75x

The problem tells us that we are driving 96 miles, so we can plug in 96 for x and solve.

R(x)=150+1.75(96)\\R(x)=150+168\\R(x)=318

The total cost of the rental is going to $318.

Hope this helps!
