we know that
m∠ZWY=m∠WXY --------> given problem
so
In the right triangle ZWY
In the right triangle XWY
<u>Find the value of b</u>
<u>Applying the Pythagorean Theorem</u>
In the right triangle XWY
therefore
<u>the answer is the option</u>
D) 9.4 units
So the point-slope form looks like (y-y1) = m(x-x1)
So the first thing we should do is solve for m. We can do this using the slope formula (y1-y2)/(x1 - x2)
(-4 - 4)/(3 - -1) = -2
So our slope is -2. Then plug in any order pair for y1 and x2
So a possible solution is y - 4 = -2(x + 1)
Hopes this helps!
Answer:
- <u>$45</u> (with the assumption made below)
Step-by-step explanation:
The equation is garbled; thus, to explain you I will assume the equation is
Where:
- R(s) is the revenue in dollars, as a function of the number of seats occupied.
- s is the variable that represents the number of seast occupied
- 14 is the rate of change of the revenue per seat occupied (the price of a ticket).
- -325 is the fixed cost of the theater for a performance (the amount of money the theater will lose if none seat is occupied).
Thus, you can predict the revenue when 70 seats are occupied by substituting s with 70.
- R(70) = -325 + 980 = $655
The <em>residual value</em> from a prediction is equal to the real value (observed value) less the preducted value:
- Residual = real revenue - predicted revenue
- Residual = $700 - $655 = $45
