Simplify the following:
4 sqrt(32) + 6 sqrt(50)
sqrt(32) = sqrt(2^5) = 2^2 sqrt(2):
4×2^2 sqrt(2) + 6 sqrt(50)
2^2 = 4:
4×4 sqrt(2) + 6 sqrt(50)
sqrt(50) = sqrt(2×5^2) = 5 sqrt(2):
4×4 sqrt(2) + 6×5 sqrt(2)
4×4 = 16:
16 sqrt(2) + 6×5 sqrt(2)
6×5 = 30:
16 sqrt(2) + 30 sqrt(2)
16 sqrt(2) + 30 sqrt(2) = 46 sqrt(2):
Answer: 46 sqrt(2)

Firefighters used a ladder 50 feet high to reach a window that was 30 feet above the ground. From the same point on the ground,
deff fn [24]
First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40    Line BL = 40 ft
Since the ladder is 50 feet it is the same length on the other side as well
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30        line LM is 30 ft
SO line lm + line bl = 30 + 40 = 70 ft
A is true because ^
B isn't true because as we solved for earlier, BL is 40
C is true because line LM is in fact 30 ft as we solved for
D is not true because as we said earlier BM is 70
E is true because the same ladder was used on both sides of the street

A rule was used to create this list of points. Is the rule a function or not a function?
posledela

Answer:

As we know, a function can't have the same x coordinate but can have the same y coordinate.

I found -6 twice for the x coordinate.

If we were to graph this, a function would only have 1 point on each VERTICAL line, not 2

Therefore, it is not a function

AfilCa [17]

Answer: C 1*10^5

Step-by-step explanation:

There are 10^2 cm in a meter, and 10^3 meter in a kilometer, so there are 10^2 * 10^3 = 10^5 cm in a kilometer
