Graph B is the answer


JulsSmile [24]3 years ago
7 0

First I would isolate the "y" in the inequality(you don't have to but it makes the inequality look simpler):

y - 5 > 2x - 10  Add 5 on both sides

y > 2x - 5

[This is kind of the same form as y = mx + b ("m" is the slope, "b" is the y-intercept (when x = 0)), except there is a sign(< , > , ≤, ≥) instead of an equal sign. So your slope is 2, and your y-intercept is -5.]


Only when the sign is ≤ or ≥ ("less/greater than <u>or equal to</u>"), the line is a solid line. When the sign is < or >, the line is a dotted line.


Based on the inequality, "y" is greater than the line (2x - 5), so the shaded area would be above the line. And because the sign does not have a line underneath, it is a dotted line.


Your answer is B

Answer:  B. H(t) = -6.9(t - 2.3)² + 112

<u>Step-by-step explanation:</u>

The vertex form of a quadratic equation is: y = a(x - h)² + k

where (h, k) is the vertex   ⇒    k is the maximum height

the distance traveled is when y = 0     ⇒    x=\sqrt{\dfrac{-k}{a}}+h

Given: H(t) = -7.1(t - 2.3)² + 98

maximum height (k) = 98 feet

distance traveled (x) = \sqrt{\dfrac{-98}{-7.1}}+2.3    = 6.02 seconds

A) H(t) = -7.5(t - 2.2)² + 112

maximum height (k) = 112 feet

distance traveled (x) = \sqrt{\dfrac{-112}{-7.5}}+2.2    = 6.06 seconds

B) H(t) = -6.9(t - 2.3)² + 112

maximum height (k) = 112 feet

distance traveled (x) = \sqrt{\dfrac{-112}{-6.9}}+2.3    = 6.33 seconds

C) H(t) = -6.9(t - 2.4)² + 95

maximum height (k) = 95 feet

This has a lower height than the given equation.

D) H(t) = -7.5(t - 2.3)² + 95

maximum height (k) = 95 feet

This has a lower height than the given equation.

Both options A and B travel higher and stay in the air longer than last year's winner, however option B stays in the air longer than option A.

I need someone to explain functions and functional symmetry to me. This is very important, so if you do not have a legit answer,
dolphi86 [110]

Symmetrical functions can be about the x and y axis. Essentially, if we reflect the graph across the y or x axis, we get the same graph. Some other graphs can be reflected across both the x and y axis at the same time and be symmetrical. These can be classified as odd and even functions. You can test this by replacing x and y with -x and -y and simplify the equation. If the results comes out to be the same as the original, it is symmetrical across the origin.

Best of Luck!
