Answer:
5X + 8Y >= 300; intersection at (-20, 50)
Step-by-step explanation:
let t = work hours
0 < t < 30
X = time lawn mowing
Y = time babysitting.
X + Y < 30
5X + 8Y >= 300
We could solve...
X < 30 - Y
5(30 - Y) + 8Y >=300
150 - 5Y + 8Y >= 300
3Y >=150
Y >=50
then X < -20
intersection at (-20, 50)

Snezhnost [94]

Answer:

  4√41 ≈ 25.61 feet

Step-by-step explanation:

The shortest route is the one that crosses the longest edge between room surfaces. In this case, that is the 16-foot edge between the floor and wall opposite the amplifier, or the 16-foot edge between the ceiling and the wall adjacent to the amplifier.

The length of the required wire is ...

  √((8+12)² +16²) = √656 = 4√41 ≈ 25.61 . . . feet

Calculate the area of each triangle using two different methods
timurjin [86]
The area of a triangle is 1/2 bh
so to find the area of the larger triangle do the following calculation:
1/2 time 12 time 7. that will give you 42 ft squared.  that is the larger triangle. 
the next way to find the area i will show you is:

pretend that the the triangle is inside of a rectangle. now you have 4 triangles. you know that the base of the rectangle is 15 ft anf the height is 7. now take the smaller triangle and it has its rectangle base 3 and height 7. multiply to get 21 feet squared. divide by 2 since there are 2 triangles in the small rectangle. 10.5 feet squared

How can help me with this operation about Pre-Calculus.<br>Simplify
Mrrafil [7]

If we want to compute f(2+h), we have to substitute every occurrence of x with 2+h in the definition of the function:

f(x)=x^2-11x \implies f(2+h) = (2+h)^2-11(2+h) = 4+4h+h^2-22-11h = h^2-7h-18

Similarly, computing f(2) means to substitute the input with 2:

f(x)=x^2-11x \implies f(2) = 2^2-11\cdot 2 = 4-22 = -18

So, we have

f(2+h) - f(2) = h^2-7h-18 - (-18) = h^2-7h

And finally

\dfrac{f(2+h)-f(2)}{h} = \dfrac{h^2-7h}{h} = h-7
