An 11 foot ladder leans against the side of a house. The bottom of the ladder is 6 feet from the side of the house. How high is

Mariulka [41]

Using Pythagoras Theorem,
(b is the length of the ladder from the ground)
11x11=6x6+(b^2)
121-36=(b^2)
85=(b^2)
b= 9.219544457292887
b is approximately 9.2

Answer:

C, 108 ft²

Step-by-step explanation:

To solve, we need to find the area of each of the shapes and then add them together.

The top rectangle's area: 8 * 3 = 24

The left triangle: 3 * 4 * 0.5 = 6

The middle rectangle: 8 * 4 = 32

The right triangle: 4 * 3 * 0.5 = 6

The bottom rectangle: 5 * 8 = 40

Add them all together.

24 + 6 + 32 + 6 + 40 = 108 ft²

Thus, the answer is C, 108 ft²

Several co-workers carpool to work each day. the daily cost of gas and tolls, $12, is split evenly among the people who carpool

Verizon [17]

Answer:

c(x) = ($12) / x

Step-by-step explanation:

The general formula for inverse proportion is y = k/x.

In this specific problem, y represents the cost per person, k the dailyl cost ($12), and x the number of perople riding.

Then

c(x) = cost per person as a function of the number of people riding

= ($12) / x

Note that if only one person rides, that person pays $12/1, or $12; if two people, $12/2, or $6 per person, and so on.

Determine the direction that this parabola opens y=4x^2+8x+2

just olya [345]

For this case we have a quadratic equation of the form:
$ax ^ 2 + bx + c
$
What we must keep in mind to know which direction opens the parabola, is the value of a.
We have two options:
If a <0 the parabola opens down
If a> 0 the parabola opens up
We have the following equation:
$y = 4x ^ 2 + 8x + 2
$
We observed that:
$a = 4 (a\ \textgreater \ 0)
$
Therefore, the parable opens up.
Answer:
the direction that this parabola opens is:
Upwards
