I will convert feet to inches.
4 feet, 6 inches = 54 inches
20 feet = 240 inches
5/x = 54/240
Let x = closest height of tree
54x = 5(240)
54x = 1,200
x = 1200/54
x = 22.2222222222
The tree is about 22 feet tall.
Answer:
The range is y ≥ -1
Step-by-step explanation:
∵ f(x) = (x - 4)(x - 2)
∴ f(x) = x² - 2x - 4x + 8
∴ f(x) = x² - 6x + 8 ⇒ quadratic function (ax² + bx + c) represented by
parabola graphically
∵ a = 1 , b = -6 , c = 8
∴ x-coordinate of its vertex = -b/2a = -(-6)/2×1 = 3
∴ f(3) = (3)² - 6(3) + 8 = -1
∵ a is positive ⇒ the curve has minimum point and it's open upward
∴ the minimum point is (3 , -1)
∴ The range is y ≥ -1 ⇒ because the minimum value is -1
The graph will slant to the right or it will be increasing.
I think they are look for the answer, INCREASING.
Distance = speed * time
d = 65.2 * 1.8
d = 117.36 miles <==
Answer:
Distance is 6.7units to the nearest tenth.
Explanation:
To solve this problem, we the distance formula. And this is given as:

We were given the equation:
y = 2 x + 4
This can also be rewritten as:
y – 2 x – 4 = 0.
Therefore, a = -2, b = 1 and c = -4
Also, we were given the points:
(x, y) = (–4, 11)
Making use of the above formula for distance, we have:


D = 6.7units (to the nearest tenth)
