Answer:
Step-by-step explanation:
The given functions are:
and
Now,
The domain refers to values of 
for which is defined.
The expression under the radical sign must not be negative.
The domain is
$22.50
You can get this by dividing the new total by 116%, which is how much of the bill was paid.
Answer:
RS = 17
Step-by-step explanation:
QS = 62
RS = ?
QR = 45
QS - QR = RS
62 - 45 = 17
Thus RS = 17
Answer:
(-12, -1)
Step-by-step explanation:
(8, -1) => (-2/3x, f(-2/3x))
therefore
-2/3x = 8
x = 8 *-3/2
x = -12
f(-2/3x) = -1
therefore, the corresponding point is:
(-12,-1)
Answer:
1240.4 mm²
Step-by-step explanation:
The surface area of a pyramid = Area of the all sides + Area of base
Each side is a triangle.
With a regular pentagonal pyramid, the area of each triangle is
For the 5 triangles,
Substituting given values,
Area of base = 440.4 mm²
Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²
