The formula that relates the length of a ladder, L, that leans against a wall with distance d from the base of the wall and the height h that the ladder reaches up the wall is mc024-1.jpg. What height on the wall will a 15-foot ladder reach if it is placed 3.5 feet from the base of a wall?

Answers

We will use the Pythagorean theorem to determine the height: $h^(2)=15^(2) - 3.5^(2)$ $h^(2) =225 - 12.25=212.75$ Finally: $h= √(212.75)=14.5859$

50/8 converted as a mixed number

Answers

50/8

Simply divide 8 into 50. That is 6. Because 8 *6 = 48.

There would be a remainder of 2.

So 50/8 = 6 whole number 2/8.

So the answer = 6 whole number 2/8. As mixed fraction.

You can reduce the 2/8 to 1/4.

So 6 whole number 1/4 is also correct.

6 1/4 because do 50÷8=6 (remainder: 2)

So it is 6 2/8. Simplify it and it will be 6 1/4.

Please answer all three questions for full points.

7. $(f(4 + h) - f(4))/(h) = 8$
   $h((f(4 + h) - f(4))/(h)) = h(8) \nf(4 + h) - f(4) = 8h$
   $(h + 4)^(2) + (4)^(2) = 8h \n(h + 4)(h + 4) + 16 = 8h \nh(h + 4) + 4(h + 4) + 16 = 8h$
   $h(h) + h(4) + 4(h) + 4(4) + 16 = 8h \nh^(2) + 4h + 4h + 16 + 16 = 8h$
   $h^(2) + 8h + 32 = 8h \nh^(2) + 32 = 0$
   $h = \frac{-(0) \± \sqrt{(0)^(2) - 4(1)(32)}}{2(1)}$
   $h = \frac{0 \± \sqrt{(0)^(2) - 4(1)(32)}}{2}$
   $h = (0 \± √(-128))/(2)$
   $h = (0 \± 8i√(2))/(2)$
   $h =(8i√(2))/(2)$
   $h = 4i√(2)$

8. $f(x) = (x^(2) + 4x - 32)/(x - 4) \nf(x) = (x^(2) + 8x - 4x - 32)/(x - 4) \nf(x) = (x(x) + x(8) - 4(x) - 4(8))/(x - 4) \nf(x) = (x(x + 8) - 4(x + 8))/(x - 4) \nf(x) = ((x - 4)(x + 8))/(x - 4) \nf(x) = x + 8$

$g(x) = x(2x - 5) - 2(x^(2) - 3x - 4) \ng(x) = x(2x) - x(5) - 2(x^(2)) + 2(3x) + 2(4) \ng(x) = 2x^(2) - 5x - 2x^(2) + 6x + 8 \ng(x) = 2x^(2) - 2x^(2) - 5x + 6x + 8 \ng(x) = x + 8$

The functions are equivalent.

Answer:

B=59

Step-by-step explanation:

59 is across from B so they are equal.

Answer:

b = 59

Step-by-step explanation:

b is located right across from the 59 degrees, and they are separated by the same 2 lines that make up their angles. Therefore causing them to have the same measurement, making b = 59
