Abby wants to use her savings of 1,325 to learn yoga. The total charges to learn yoga include a fixed registration fee of $35 an
NISA [10]

Answer:

Maximum number of months Abby can learn yoga is 25 months.

Step-by-step explanation:

We have given,

Total savings of Abby = $1325

Total charges to learn yoga is given as:

A fixed registration fee = $35

And a monthly fee = $50

Since the registration Abby pays only once. So we can calculate the remaining saving amount for Abby.

i.e Remaining saving amount after registration fee = $ (1325 - 35) = $1290

Now, from the remaining amount after paying registration fee , let the Abby learn yoga for x months.

To find maximum number of months we need to satisfy a equation given as:

x*50 \leq 1290

or x\leq \frac{1290}{50} \\x\leq 25.8

Since we got x ≤ 25.8 months   ≈ 25 months (in integer form)

So maximum number of months Abby can learn yoga is 25 months.

Given this function: f ( x )=−2cos(4 πx ) Find the following:
Neporo4naja [7]

Answer:

Period =½

Equation of midline, y=0

Maximum =2

Minimum=-2

Step-by-step explanation:

The given function is

f(x) =  - 2 \cos(4 \pi \: x)

The period is given by:

\frac{2\pi}{b}  =   \frac{2\pi}{4\pi} =  \frac{1}{2}

The equation of the midline is y=0 since there is no vertical shift

The amplitude of this function is 2 so the range is -2≤y≤2.

Hence the maximum value is 2 and minimum value is -2

Create a linear equation in the slope-intercept form that contains points (2,−8) and (6,−4) .
nadezda [96]

Answer:

y = x - 10

Step-by-step explanation:

Find the slope:

-4 - (-8) ÷ 6 - 2

-4 + 8 ÷ 6 - 2

4 ÷ 4

= 1

Substitute into the slope-intercept equation:

y = mx + b

Let's use the first coordinate (2,-8) for the x and y values

m = 1

-8 = 1(2) + b

-8 = 2 + b

-2    -2

-10 = b

Write equation:

y = 1x -10 or y = x -10
