For the function given, state the middle line: ƒ(t) = 3 cos(π t − 1).

1 answer:

8 0

Cos (πt - 1) oscilates periodically between -1 and +1.

3Cos (πt - 1) oscilates periodically between -3 and +3.

The x-axis is the middle line. The equation of the x-axis is y = 0.

So the, the middle line is y=0.

How is the graph of the parent function of y = RootIndex 3 StartRoot 0.5 x EndRoot transformed to produce the graph y = RootInde

lana66690 [7]

Answer:

Horizontal stretch by a factor of ½.

Step-by-step explanation:

We were given the parent function as:

$y = \sqrt[3]{0.5x}$

This was transformed to:

$y = \sqrt[3]{x}$

Let

$g(x) = \sqrt[3]{0.5x}$

and

$f(x) = \sqrt[3]{x}$

Then:

$f(x) = g(2x)$

Hence the parent function has been stretched horizontally by a factor of 1/2 to obtain the transformed function.

Casey wants to put new carpet in her bedroom. A drawing of Casey's room is below. It consists of two sections: a square and a re

natulia [17]

Answer: Casey should buy 48 square yards of carpet

Step-by-step explanation: If Casey's room has two sections, which are a square section and a rectangular section, we shall calculate the total area of each section separately to start with. The square section has sides measuring 4 yards each, then the area of that section can be calculated as;

Area = 4 x 4 (all sides of a square are equal in length)

Area = 16 square yards.

Also the rectangular section has the same width as the square section, that is, 4 yards. The rectangular section has twice the length of the square section, that is, twice of 4 yards which is 8 yards. Hence the area of the rectangular section is calculated as;

Area = 4 x 8

Area = 32 square yards

Therefore, the total measurement of carpet in square yards for her room shall be area of both sections added together.

Total area = 16 square yards + 32 square yards

Total area = 48 square yards
