Make sure you keep all units the same. If the answer wants m, and the problem is in cm, make sure you convert all units to be the same as the answer before you work the problem. Don't forget to label the units in your final answer, and when you have your answer, ask yourself if it makes sense for what the problem was. Ex: Would the garden in the backyard really be 2,000 ft? Hope this is what you needed...
Answer: D) 10 sin (πx) - 5
<u>Step-by-step explanation:</u>
The range (maximum - minimum) is 5 - (-15) = 20
The amplitude (A) is range (20) ÷ 2 = 10
The vertical shift (D) is maximum (5) - amplitude (10) = -5
Of the given options, only A & D are candidates. Now we need to decide if it is a cos graph (A) or a sin graph (D). If we shift the graph up 5 units (to eliminate the vertical shift) , the graph would pass through the origin. Thus it is a sin graph and the answer must be option D.
Answer:
the sum of 1.25+(0.75)=2.00
The given function has infinite number of solutions
let x = 0
y = -2
let x = 1
y = 3 -2 = 1
x is the independent variable and can take any value while y the dependent variable gets its value out of the function.
Answer:
$960
Step-by-step explanation:
Let the original amount be = x
Percentage increase is equal to = 12.5%
final amount = original amount + increase
final amount = x + 0.125x
final amount = 1.125x
final amount = 1080 = 1.125x
and then solve for x
![x = \frac{1080}{1.125} \\ \\ x = 960](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B1080%7D%7B1.125%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%20960)
so in the end x is equal to $960
Solve the equation: 1080 = 1.25x
