Consequently, it costs $62.70 to make cupcakes for two hours.

By making use of functions, We have: n(h) = 3h, The cost in terms of hours h is given by C(3h) = 60+1.35h, and Lisa's cost for making cupcakes for 2 hours is $62.70

According to the question, Lisa makes 3 dozen cupcakes an hour. To calculate how many she makes in h hours, we will apply the equality postulate as stated.

3 dozens = 1 hour

Hour = n(h)

Cross Multiplying,

n(h) × 1 = 3×h

n(h) = 3h

Therefore, n(h) = 3h is the function that predicts the number of cupcakes Lisa produces in h hours.

We shall locate the composite function C(n(h)) to obtain the cost function in hours.

C(n(h)) = C(3h) (3h)

If C(n) = 60 + 0.45n, then

By replacing n with 3h in the function as indicated, C(3h) is obtained;

C(3h) = 60+0.45(3h) (3h)

C(3h) = 60+1.35h

Thus, 60+1.35h is the cost function expressed in hours.

We will change h = 2 into the calculation C(h) = 60+1.35h to obtain the cost of baking cupcakes for 2 hours.

C(2) = 60+1.35(2) (2)

C(2) = 60+2.70

C(2) = 62.70

Consequently, it costs $62.70 to make cupcakes for two hours.

Explanation

We will first sketch this triangle.

Let the short leg of the triangle be x

In a right-angle triangle, the side opposite the right angle is the Hypotenuse, the side opposite the given angle that is non-right angle is the Opposite and the remaining side is the Adjacent.

So, after noting the three sides in a right triangle, we will then use trignometric ratios to solve for any of the unknown. If the non-right-angle angle given is θ, the trignometric ratios in short forms are written as

SOH, CAH and TOA

SOH means Sin θ = (Opp/Hyp)

CAH means Cos θ = (Adj/Hyp)

TOA means Tan θ = (Opp/Adj)

So, the one to be used depends on the sides of the triangle that are provided.

For this triangle, using the angle 60° as the non-right-angle angle

Hypotenuse = ?

Opposite = 3√2

Adjacent = x

Angle = 60°

TOA means Tan θ = (Opp/Adj)

Tan 60° = (3√2)/x

Tan 60° = √3

Tan 60° = (3√2)/x

√3 = (3√2)/x

Cross multiply

x = (3√2)/(√3)

x = (√3) (√2)

x = √6

John's paycheck is $2,000.

According to the question,

We have the following information:

John saves 2/5 of his take-home pay.

After 6 paychecks, he has saved $4,800.

Now, let's take John's paycheck to be $x.

Now, 2/5 of this paycheck will be $2x/5.

So, this is the amount saved from 1 paycheck of John.

Now, to find the amount saved in 6 paychecks will be:

6*(2x/5)

Now, we can equate this to the amount saved by John after 6 paychecks.

6*(2x/5) = $4,800

12x/5 = 4800

12x = (4800*5)

x = (4800*5)/12

Now, dividing 4800 by 12:

x = 400*5

x = $ 2000

Hence, the correct option is C ($2,000).

The length of the rafter when the architect design a house is 12.778m.

The information illustrates that the architect designs a house that is 10 m wide and that the rafters holding up the roof are equal length and meet at an angle of 65°.

The rafters extend 0.4 m beyond the supporting wall. Then, the length will be:

cos65° = BC / AC

cos 65° = (5 + 0.4)/x

cos 65° = 5.4/x

x = 5.4 / 0.4226

The parachutes speed during free fall will be : 990 feet per second

Given: A parachute speed during a free fall = 135 miles per hour.

This means Unit rate = 135 miles per hour

R90° transformation results in an image point that is (6, -8).

The plane is divided into four infinite areas known as quadrants, each of which is bounded by two half-axes, using two-dimensional Cartesian axes.

These are commonly numbered from 1 to 4, and are denoted by Roman numerals: the coordinates for I are I (+, +), II (-, +), III (-, -), and IV (+, -).

We are aware that there are four quadrants: I (x, y), II (-x, y), III (-x, -y), and IV (-x, -y) (x, -y)

We can infer that the points are in quadrant III from the supplied point, which is (-6, -8). (-x, -y).

Now, if we turn right 90 degrees and enter sector IV (x, -y), the supplied point will change to (6, -8)

We have the following equation:

y - 4 = 1/3 (x + 2)

We clear y in order to be more unterstandable:

y - 4 = 1/3 (x + 2)

y = 1/3 (x + 2) + 4

y = 1/3 x + 2/3 + 4

y = 1/3 x + 2/3 + 12/3

y = 1/3 x + 14/3

In order to find the answer we are going to determine x value when y = 4:

y = 1/3 x + 14/3

4 = 1/3 x + 14/3

4 - 14/3 = 1/3 x

12 - 14 = x

-2 = x

Then, it passes through the point (-2 , 4), so we can discard options A and B (because it doesn't pass through (2, 4))

We know a linear equation is given by:

y = mx + b, where m and b are numbers: m is the slope of the line and b the y-intercept.

In this case y = 1/3 x + 14/3, the slope is 1/3. We know m is given by

m = Δy/Δx

Since in this case

m = 1/3 = Δy/Δx

Then

Δx = 3 and Δy = 1

That means that if it changes 3 units on the x-axis, then it changes 1 unit on the y-axis

Step-by-step explanation:

Given the sequence x, 7, 11, 15, ... 399, where 399 is the 100th term, you want to know the first term, x.

The differences of the first few terms are ...

  11 -7 = 4

  15 -11 = 4

This suggests an arithmetic sequence with a common difference of 4.

The first term, x, will be 4 less than the second term:

  x +4 = 7

  x = 7 -4 = 3

The value of x is 3.

Explanation:

Let's label some points in the triangle as:

Since the sides of the triangles are tangent to the circumference, we can write the following relationships:

XC = YC

AZ = AY

BX = ZB

So, the length of the missing side XC is equal to:

XC = YC = 14

On the other hand, the length of AB is the sum of the length of AZ and ZB, so we can calculate ZB as:

AB = AZ + ZB

26 = AY + ZB

26 = 18 + ZB

26 - 18 = ZB

8 = ZB

Because AZ and AY have the same length.

Finally, the measure of BX is equal to:

BX = ZB

BX = 8

Therefore, the perimeter of the triangle is:

Perimeter = AY + YC + AZ + ZB + BX + XC

Perimeter = 18 + 14 + 18 + 8 + 8 + 14

Perimeter = 80

So, the answer is 80 units.
