A 30-foot ladder is set against the side of a house so that it reaches up 24 feet. If Elizabeth grabs the ladder at its base and pulls it 3 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 21 ft.) Round to the nearest tenth of a foot.

Answer:

The answer is D, sqrt(41)in.

Step-by-step explanation:

The question is asking about the hypotenuse L. You can get that by using the Pythagorean Theorem( a^2+B^2=C^2). You can get the bottom length of the triangle by dividing 8 by 2, because the triangle is made from the top point of the pyramid. You can there do 5^2+4^2, which is 41. You then need to take the square root of that, or [tex]\sqrt{41}[/tex].

Answer:

Hello! Your answer would be, D) [tex]\sqrt{41} in.[/tex]

Answer:

Z'(9, - 1)

Step-by-step explanation:

For a 90 degree counterclockwise rotation about the origin,

The original coordinates of point P (x,y) will now be positioned as P' (-y,x).

Hence, given :

Triangle XYZ with X(-7,-9), Y(-10,-3), and Z(-1,-9)

The new position of Z denoted as Z' will be :

Z(-1, - 9) ; X = - 1 ; y = - 9

-y = - - 9 = 9

x = - 1 will remain as - 1

Z(-1, - 9) - - - > Z'(9, - 1)

Answer:

-8/19

Step-by-step explanation:

-11/19 + 3/19

Using an exponential function, it is found that 0.08 ml of the will be in the body in 30 hours.

The amount of a decaying substance is modeled by an exponential function in the following format:

[tex]A(t) = A(0)e^{-kt}[/tex]

In which:

In this problem, the half-life is 6 hours, which means that [tex]A(6) = 0.5A(0)[/tex], and this is used to find k.

[tex]A(t) = A(0)e^{-kt}[/tex]

[tex]0.5A(0) = A(0)e^{-6k}[/tex]

[tex]e^{-6k} = 0.5[/tex]

[tex]\ln{e^{-6k}} = \ln{0.5}[/tex]

[tex]-6k = \ln{0.5}[/tex]

[tex]k = -\frac{\ln{0.5}}{6}[/tex]

[tex]k = 0.11552453009[/tex]

Hence:

[tex]A(t) = A(0)e^{-0.11552453009t}[/tex]

2.5 ml injection, hence [tex]A(0) = 2.5[/tex]

After 30 hours, we have to find A(30), hence:

[tex]A(t) = 2.5e^{-0.11552453009t}[/tex]

[tex]A(30) = 2.5e^{-0.11552453009(30)}[/tex]

[tex]A(30) = 0.08[/tex]

0.08 ml of the will be in the body in 30 hours.

Step-by-step explanation:

Given that Ethan has packed 6 shirts, 4 pairs of pants and 2 pairs of shoes for vacation, to determine how many possible outfit combinations does Ethan have for his trip the following calculation must be performed:

Shirts x pants x shoes = Number of combinations

6 x 4 x 2 = X

24 x 2 = X

Answer:

Point of intersection is - (x, y) = (1, 2)

Step-by-step explanation:

Given - y=3x-1 y=2x

To find - For each pair of equations draw the lines for each the point of intersection represents the sol.

Proof -

Given that, the two lines are

y = 3x - 1            .........(1)

y = 2x                 .........(2)

For the intersection point, Compare the two equations (1) and (2)

By comparing, we get

3x - 1 = 2x

⇒3x - 2x - 1 = 0

⇒x - 1 = 0

⇒x = 1

Now,

Put the value of x in equation (1), we get

y = 3(1) - 1

   = 3  - 1

   = 2

⇒y = 2

∴ we get

Point of intersection is - (x, y) = (1, 2)

Answer:

The salary of Sydney to meet the loss due to inflation should be 11.85 per hour

Step-by-step explanation:

The inflation rate is 3%

This means that the alary amount will reduce by 3%.

3% of Sydney's hourly salary is

[tex]\frac{3}{100} *11.50[/tex] = 0.345

Hence, the new salary must increase by 0.345 dollar per hour

The salary of Sydney to meet the loss due to inflation should be 11.50 + 0.345 = 11.845 or 11.85
