Answer:
C
Step-by-step explanation:
The inverse of the function would have the x-values and y-values swapped. To find the inverse of a function, the x('s) and the y('s) would be swapped. C is the only one with the x-values and the y-values swapped, and thus, is the correct answer.
I hope this helps. :)
Answer:
Total = $49.05
Step-by-step explanation:
cost of grapes per pound = $ 2.50
she bought 3 pounds of grapes
so cost of 3 pounds of grapes = 3 × 2.50
= 7.5
gallon of milk = 8.6 pound
so cost of 8.6 pound of milk = 8.6 × 4.25
= $36.55
$ 1.50 off means =$4 - $ 1.50 = $2.5
cost of 2 boxes of cereal = 2 × 2.5
= $ 5
Total = 7.5 + 36.55 + 5
Total = $49.05
The height of the antenna on the roof of the local building is approximately 8 meters.
The situation forms a right angle triangle.
<h3>Properties of a right angle triangle:</h3>
- One of its angles is equals to 90 degrees
- The sides of the triangles can be calculated using Pythagoras theorem.
Therefore, let's find the height of the building and the radio antenna from the eye point.
Using trigonometric ratios,
tan 40° = opposite / adjacent
tan 40° = x / 25
where
x = the height of the building and the radio antenna from the eye point.
x = 25 tan 40
x = 25 × 0.83909963117
x = 20.9774907794 meters
Let's find the height of the building from his eye point.
tan 28° = y / 25
where
y = height of the building from his eye point
y = 25 × tan 28°
y = 25 × 0.53170943166
y = 13.2927357915 meters
Height of the antenna = 20.9774907794 - 13.2927357915 = 7.68475498786
Height of the antenna ≈ 8 meters

Answer:
15m
Step-by-step explanation:
When Ana is diving the time=0 therefore just substitute x=0 into h(x) and it will give you 15m
f( x ) = - 1/3 x + 5
