The table below shows the relationship between the number of teaspoons of baking powder in a mix and the height of fudge brownie
rosijanka [135]

Answer:

Option A. y=0.28x+0.75

Step-by-step explanation:

Let

y -----> the height of fudge brownies in centimeters

x ----> teaspoons of baking powder

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

take the points

(5,2.15) and (6,2.43)

substitute the values

m=\frac{2.43-2.15}{6-5}

m=\frac{0.28}{1}=0.28

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=0.28

(x1,y1)=(5,2.15)

substitute

y-2.15=0.28(x-5)

Isolate the variable y

y-2.15=0.28x-1.4

y=0.28x-1.4+2.15

y=0.28x+0.75

Car 1. (40 kph):

40 kph = 40,000 km per hour

Car 2. (15 mps)

15 mps x 60 (to get one minute) = 900 mpm

900 meter per minute

900 x 60 = 54,000 km

Therefore, car 2 is faster since it drives at 54km per hour and car 1 only travels at 40km per hour.

Also, you decide which car you want to choose.

Hope this helps! Have a great day.

The equation of the sinusoidal function is y = -2sin(x + 1.5) - 3

<h3>The sinusoidal function</h3>

The minimum and the maximum of the function are

  • Minimum = -1
  • Maximum = -5

The amplitude (A) is calculated as:

A = 0.5 * (Maximum - Minimum)

So, we have:

A = 0.5 * (-5 + 1)

A = -2

The vertical shift (d) is calculated as:

d = 0.5 * (Maximum + Minimum)

So, we have:

d = 0.5 * (-5 - 1)

d = -3

The period (P) is calculated as:

P = 2π/B

From the graph,

B = 1

So, we have:

P = 2π/1

P = 2π

So, the amplitude is -2 and the period is 2π.

<h3>The equation of the sine function</h3>

In (a), we have:

A = -2

B = 1

d = -3

A sine function is represented as:

y = A sin(Bx + C) + D

So, we have:

y = -2sin(x + C) - 3

The graph passes through the point (0, -5)

So, we have

-5 = -2sin(0 + C) - 3

Solve for C, we have

C = 1.5

So, we have:

y = -2sin(x + 1.5) - 3

Hence, the equation of the sinusoidal function is y = -2sin(x + 1.5) - 3
