Gena attached a dog ramp to her sofa, which allows her oldest dog to easily climb onto a seat cushion. The ramp is 55 inches lon
matrenka [14]

The distance from the base of the ramp to the base of the sofa rounded to the nearest tenth is 47.3 inches.

<u><em>Explanation</em></u>

According to the diagram, length of the ramp is, AC= 55 inches. The top of the seat cushion is 28 inches above the floor. That means, BC=28 inches

We need to find the distance from the base of the ramp to the base of the sofa which is AB

In right angle triangle ABC, using Pythagorean theorem...

AC^2 = AB^2 + BC^2\\ \\ (55)^2= AB^2 + (28)^2 \\ \\ AB^2 = (55)^2 - (28)^2 \\ \\ AB^2 = 3025 - 784\\ \\ AB^2 = 2241\\ \\ AB = \sqrt{2241}= 47.3

So, the distance from the base of the ramp to the base of the sofa rounded to the nearest tenth is 47.3 inches.

Consider the function f(x) = 20/√x and its second-degree polynomial P2 (x) = 20 - 10(x-1) + 7.5(x-1)^2 at x=0.8. Compute the val
krok68 [10]

Answer:

f (0.8) = 22.3607 and P_{2} (0.8) = 22.300.

Step-by-step explanation:

According to the statement, f (x) = \frac{20}{\sqrt{x}}  and  P_{2}(x) = 20 - 10 (x-1) + 7.5 (x-1) ^ 2. Based on these definitions, at x=0.8 produce:

f (0.8) = \frac{20}{\sqrt {0.8}} = 22.3607.  On the other hand, you have to:

P_{2} (0.8) = 20 - 10 (0.8 -1) +7.5 (0.8 -1)^2

P_{2} (0.8) = 20 - 10 (-0.2) +7.5 (-0.2)^2 = 22.300

Then, it can be affirmed that f (0.8) = 22.3607 and P_{2} (0.8) = 22.300.

Convert 5,000 inches to feet
borishaifa [10]

There are 12 inches in one foot:

1 ft = 12 in

We want to find how many feet are in 5000 inches:

x ft = 5000 in

Set up a proportion:

1/12 = x/5000

Cross multiply:

12x = 5000

Divide by 12:

x is about 416.67 feet.
