Complete Question:
The profile of a dam is modeled by the equation y = 24 (StartFraction x Over 10 EndFraction) squared, where x represents horizontal distance and y represents height, both in meters.
Point Z is at a horizontal distance of 15 meters from the left-most point of the dam. What is the height of the dam at point Z?
Answer:
The height is 36 meters
Step-by-step explanation:
Given
Required
The interpretation of the question is to determine the value of y when x = 15
Substitute 15 for x in:
<em>The height is 36 meters</em>
Answer:
The answer is A, the measure of angle Z is 45°.
Step-by-step explanation: According to base angle theorem for iscoscles triangles, the base angles must be the same angle measure if the sides opposite to them are congruent. Since it is an iscoceles triangle, they are automatically congruent. This means that Y is 90 degrees. This fits into triangle sum theorem because if Z is 45 degrees, than x is also 45 degrees making a viable triangle. This means that this is the only one that actually applies. B is wrong because of triangle sum theorem, C is wrong because of triangle sum theorem, and D is wrong because of the SSS postulate and CPCTC.
Combine like terms (terms with the same variable (letter)). Remember to bring the sign.
4c - 4d + 8c - 3d
4c + 8c = 12c
-4d - 3d = -7d
12c - 7d is your answer
hope this helps
Answer:
w(9) = -20
Step-by-step explanation:
In order to find this, take the w function and input 9 in for all the x values.
w(x) = -2x - 2
w(9) = -2(9) - 2
w(9) = -18 - 2
w(9) = -20
Well there’s no picture for me to go off of so I will give you an easy enough explanation of what I think this is supposed to be.
You’re basically going to go left side three points and down five for every point on the graph (aka ABC) and once you do that label the abc marks with an apostrophe like so; A’B’C’ for every time you change places (I think this is mostly accurate so good luck)
