Answer:
x1/2
Step-by-step explanation:
Simplify the following:
(3 x1)/6
Hint: | In (x1×3)/6, divide 6 in the denominator by 3 in the numerator.
3/6 = 3/(3×2) = 1/2:
Answer: x1/2
The height of the pole = 129.3 ft
sin 36° = height of pole/ hypotenuse
hypotenuse = 220 ft
the height of the pole = 220 sin 36° = 129.3 ≈ 129 ft
log(4) + log(2) - log(5)
= log(2²) + log(2) - log(5)
= 2 log(2) + log(2) - log(5)
= 3 log(2) - log(5)
= log(2³) - log(5)
= log (2³/5)
= log (8/5)
= log (1.6) = 0.2041... (rounded)
Answer:

Step-by-step explanation:
Use the slope-intercept formula:
where m is slope and b the y-intercept.

Use the slope formula for when you have two points:

Rise over run is the change in the y-axis over the change in the x-axis. Insert values:

Simplify parentheses (negative+negative=positive)

Simplify

2 is the slope:

Now use one of the points to find the y-intercept by substituting the x and y values into the equation. Solve for b:
(4,7)


The y-intercept is -1. Insert into the equation. Change the + symbol to -:

Done.
The roots of the parabola is where the x-intercepts are so the answer is x=-1 and x= 5
