∑ Hey, hughesbillyrobert ⊃

Answer:

y = 0.75x + 9

Step-by-step explanation:

Given:

A mother gives birth to a 9 pound baby. Every 4 months, the baby gains 3 pounds. If x is the age of the baby in months, then y is the weight of the baby in pounds. Find an equation of a line in the form y = mx + b that describes the baby's weight.

y = ________________

Solve:

For the equation of the line of the form y = mx + b:

'm' which is the slope of the line

' b' which is the y-intercept and that is the value of y when x is equal to zero.

The slope is the rate of change of y per change in x.

"y" would represent the dependent variable which is the weight of the baby and "x" represents the independent variable which is the number of months or the age of the baby in months.

At birth represents the beginning of time for the baby. Lets call this month zero. Hence,

x = 0 y = 9 ⇒ at birth

x = 4 y = 12

x = 8 y = 15

x = 12 y = 18

Now we find the slope between each point. Since the common difference of y is 3 and the common difference in x is 4, the slope will be

Slope = y/x = 3/4

Therefore, the equation of the line that represents this relationship is

y = (3 / 4)x + 9

y = 0.75x + 9

Simplify the expression. Write the answer using scientific notation. 0.3(8.2 x 10^-3)

olchik [2.2K]

Answer:

0.3(8.2 x 10^-3) = 2.46 X 10 ^ -3

Step-by-step explanation:

We need to solve the equation 0.3(8.2 x 10^-3) and write answer in scientific notation.

Solving,

= 0.3(8.2 x 10^-3)

= 0.3 * 0.0082

= 0.00246

Writing in scientific notation

= 2.46 X 10 ^ -3

So, after solving the expression 0.3(8.2 x 10^-3) the result is 2.46 X 10 ^ -3.

a ferris wheel rotates 9pi/8 radians prior to making a stop the total height of the ferris wheel is 246 ft how far around did th

Zinaida [17]

Answer:

ferris wheel travel approx = 434.72 ft

Step-by-step explanation:

given data

wheel rotates = 9pi/8 radians

total height of the ferris wheel = 246 ft

solution

we can say here that height of the ferris wheel is same as the diameter of the wheel

and wheel is circular in shape

so we get here first radius of wheel that is

radius = half of diameter ..........................1

put here value and we get

radius = 0.5 × 246

radius = 123 ft

and

wheel travel distance = length of arc by a angle of wheel rotates

so here length of arc will be

arc length = radius × wheel rotates angle .....................2

put here value and we get

arc length = 123 × $\frac{9\pi }{8}$

arc length = 434.7178 ft

so ferris wheel travel approx = 434.72 ft
