Answer:
D 8 hours
Step-by-step explanation:
it has to be positive and it is obviously more than 1 hour so it has to be 8 hours by process of elimination.
It's multily
f(x) time g(x) is basically what they wnat
so
(x^2+8x+15) times (5/(x^2-9))
hold a sec, first factor each
(x+3)(x+5) times 5/((x-3)(x+3))
we get
((x+3)(x+5)(5))/((x-3)(x+3))
(x+30 cancels out
((x+5)(5))/(x-3)
(5x+25)/(x-3)
3rd option
Answer:
The numbers that 430 is divisible by are 1, 2, 5, 10, 43, 86, 215, and 430.

Answer:
- up the wall: 4√3 ft ≈ 6.9 ft
- along the ground: 4 ft
Step-by-step explanation:
The side ratios in a 30°-60°-90° triangle are 1 : √3 : 2. Since the hypotenuse of this triangle is 8 feet, the multiplier of these ratio values is (8 ft)/2 = 4 ft.
The triangle sides are ...
4 ft : 4√3 ft : 8 ft
The ladder reaches 4√3 ≈ 6.9 ft up the wall. Its base is 4 ft from the building.
Answer:
y = mx + b y = 1/4x + 1
m = 1/4
b = 1
Step-by-step explanation:
first you should distribute
y - 2 = 1/4(x - 4)
y - 2 = 1/4x - 1
and then isolate y by adding 2 to both sides of the equal sign to cancel out the negative 2 on the left
y - 2 = 1/4x - 1
+2 +2
y = 1/4x + 1
the slope (m) = 1/4
the y-intercept (b) = 1
