The transformations that are needed to change the parent cosine function to y = 0.35×cos(8(x-π/4)) are:

The transformation of a function may involve any change.

Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

If the original function is [tex]y=f(x)[/tex]A, assuming horizontal axis is input axis and vertical is for outputs, then:

For this case, we're specified that:

y = cos(x) (the parent cosine function) was transformed to

[tex]y=0.35cos(8(x-\pi/4)[/tex]

We can see its vertical stretch by 0.35, right shift by horizontal stretch by 1/8

Period of cos(x) is of  length. But 1.8 stretching makes its period shrink to

[tex]\dfrac{2\pi}{8}=\dfrac{\pi}{4}[/tex]

Thus, the transformations that are needed to change the parent cosine function to y = 0.35×cos(8(x-π/4)) are:

vertical stretch of 0.35

horizontal compression to period of  (which means period of cosine is shrunk to  which originally was  )

Step-by-step explanation:

Answer:

50 inches

Step-by-step explanation:

Given: S and E are the midpoints of BA and AM. and EM = 9

Therefore, then the length of AB = 18 and AM = 18

Use the similar triangle properties.

7/BM = 9/18

BM = (7*18)/9

BM = 7*2 = 14 inches.

Therefore, the perimeter of BAM is = AB + BM + AM

= 18 + 14 + 18

= 50 inches

Answer:

33.94

Explanation:

First start off by finding the total regardless of the 5.25 cents.

(3x8.50)+(3x1.25)+(2x1.50)=32.25

Then take that answer and multiply by your 5.25 cents per dollar

32.25x.0525 (since we're dealing with money)

then add that answer to the original 32.25

Answer: C) [tex]x\geq1\frac{1}{2}[/tex]

Step-by-step explanation:

Let's solve your inequality step-by-step.

[tex]4x-7\geq \frac{-12x+14}{4}[/tex]

Step 1: Simplify both sides of the inequality.

[tex]4x-7\geq -3x +\frac{7}{2}[/tex]

Step 2: Add 3x to both sides.

[tex]4x+3x-7\geq -3x+3x +\frac{7}{2}\\7x-7\geq\frac{7}{2}[/tex]

Step 3: Add 7 to both sides.

[tex]7x-7+7\geq\frac{7}{2} +7\\7x\geq\frac{21}{2}[/tex]

Step 4: Multiply both sides by [tex]\frac{1}{7}[/tex].

[tex]7x(\frac{1}{7}) \geq\frac{21}{2} (\frac{1}{7}) \\x\geq\frac{21}{14} \\x\geq 1\frac{1}{2}[/tex]

Step-by-step explanation:

The reciprocal of 1 1/6 is 6/7.

Answer:

7/6

Step-by-step explanation:

to find the reciprocal of a number, you need to multiply the denominator by the whole number. once you do this, you should add that number and the  numerator. leave the denominator its orginal number and your answer should be 7/6

Dylan, since he grew by 4 centimeters. Also, the starting number is lower, which means the percentage would also be bigger in the first place.

The statement that is true is option D which says, "Dish C and Dish D have approximately the same population density."

The population density of an area is the Number of Entities in that space/Total Area occupied by the population.

A scientist has four Petri dishes of different sizes. each dish contains a different number of bacteria.

It can also be written as Dp = N/A.

Because the Dp of Dish C and Dish D is approximately 0.68, we can say that they have approximately the same Dp.

Hence, "Dish C and Dish D have approximately the same population density."

Answer

option D on edg

Step-by-step explanation:

The family who spends more to run these appliances in a given 30 day period is given by: Option A: The reed family spends $13.80 more than the merrill family.

Suppose that there are two positive integer numbers( numbers like 1,2,3,.. ) as a and b

Then, their multiplication can be interpreted as:

[tex]a \times b = a + a + ... + a \: \text{(b times)}\\\\a \times b = b + b +... + b \: \text{(a times)}[/tex]

For example,

[tex]5 \times 2 = 10 = 2 + 2 + 2 + 2 + 2 \: \text{(Added 2 five times)}\\or\\5 \times 2 = 10 = 5 + 5 \: \text{(Added 5 two times)}[/tex]

For this case, the missing table for expenses of both families is:

Reed Family                                                   Appliances                

Gas range                                                  5 cents per day            

Gas dryer                                                   1 load per day-10 cents per load

Electric water heater                                90 cents per day

Typical later model refrigerator               16 cents per day

Total cost per day                                      5+10+90+16= 166 cents = $1.21

Merrill Family                                                Appliances

Electric range                                            13 cents per day

Gas dryer -                                                 1 load per day 10 cents per load

Gas water heater                                      40 cents per day

Energy Star-labeled refrigerator              12 cents per day

Total cost per day                                    13+10+40+12 = 75 cents = $0.75

Since each of them used these appliances for 30 days, so we get:

Expense in 30 days = [tex]30 \times[/tex] expense per day

Expense in 30 days = [tex]30 \times 1.21 = \$36.3[/tex]

Expense in 30 days = [tex]30 \times[/tex] expense per day

Expense in 30 days = [tex]30 \times 0.75 = \$22.5[/tex]

So, Reed family spent more.

The difference is $36.3 - $22.5 = $13.80

Thus, the family who spends more to run these appliances in a given 30 day period is given by: Option A: The reed family spends $13.80 more than the merrill family.

Answer:

$135.84

Step-by-step explanation:

Your starting checkbook balance is $134.56.

Deposits increase your balance.  Add your deposit  to the balance:  $134.56+$345.12 = $479.68

Now add up  all the checks:  

$32.19+$250.00+$16.65+$45.00 = $343.84

Checks are money taken out of your account, so you subtract them from your balance

$479.68 - $343.84 = $135.84

Answer:

a = 5

Step-by-step explanation:

let's label the triangle as a, b and c

where b is the hypotenuse and c is the adjacent of the hypotenuse a to be the height.

from the formula

a² + c² = b²

we substitute the values to find a

so,

a² + 12² = 13²

but we don't know "a" so we make it stand alone by grouping liked terms.

a² = 13² - 12²

a² = 25

we need "a" not "a²" so we take the square root of both sides to get rid of "a²" leaving "a"

[tex] \sqrt{ {a}^{2} } = \sqrt{25} [/tex]

The area of a circular pond with a radius of 8 ft is, 18.67 m².

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

The radius of circle = 8 feet

Now, We know that;

⇒ 1 feet = 0.3048 m

⇒ 8 feet = 8 × 0.3048 m

             = 2.4384 m

We know that;

⇒ Area of circle = πr²

Substitute all the values, we get;

⇒ Area of circle = 3.14 × (2.4384)²

⇒ Area of circle = 3.14 × 5.94

⇒ Area of circle = 18.67 m²
