Answer:

0.0221 cm/min

Step-by-step explanation:

Surface area of a snowball:

An snowball has a spherical format.

The surface area of an sphere is given by:

[tex]A = 4\pi r^2[/tex]

In which r is the radius(half the diameter). So in function of the diameter, we have that:

[tex]A = 4\pi (\frac{d}{2})^2 = \pi d^2[/tex]

Implicit derivative:

To solve this question, we need to find the implicit derivative of A in function of t.

The variables are A and d, so:

[tex]\frac{dA}{dt} = 8\pi d \frac{dd}{dt}[/tex]

Its surface area decreases at a rate of 5 cm2/min

This means that [tex]\frac{dA}{dt} = -5[/tex]

Find the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm

This is [tex]\frac{dd}{dt}[/tex] when [tex]d = 9[/tex]. So

[tex]\frac{dA}{dt} = 8\pi d \frac{dd}{dt}[/tex]

[tex]-5 = 8\pi*9 \frac{dd}{dt}[/tex]

[tex]\frac{dd}{dt} = -\frac{5}{72\pi}[/tex]

[tex]\frac{dd}{dt} = -0.0221[/tex]

This means that the diameter decreases at a rate of 0.0221 cm/min when the diameter is 9 cm.

Incomplete question, but I gave a guide to solve using the Empirical Rule.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

It is also important to note that the normal distribution is symmetric. This means of the 68% of the measures are within 1 standard deviation of the mean, for example, 68/2 = 34% are between 1 standard deviation below the mean and the mean, and 34% are between the mean and 1 standard deviation above the mean.

In this question:

You take the mean and the standard deviation. Then you take both bounds that the percentage asks, and see how many standard deviations each are from the mean, and you then use the empirical rule to solve.

Answer:

As a former runner upper Senior Class Secretary I can say that your classmates need the following:

1. To be respected, even when others may not respect them.

2. They need a leader who can listen to what they have to say and DO SOMETHING about it.

3. They need the feeling of commitment when given the oppurtunity to improve.

4. They need rules, guidlines and restrictions.

(I would advocate that we have a strong leader....Is it going to be you?)

Answer:

11 hours and 15 minutes (11.25)

Step-by-step explanation:

make a ratio

160:4.5

240/160=1.5

so 1 and 1/2 intervals of 4.5 hours

4.5+4.5= 9

4.5/2=2.25

9+2.25=11.25

The solution is 3.75 hours

The time taken by Jackie to drive a distance of 240 miles is given by the equation A = 3.75 hours

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the equation be represented as A

Now , the value of A is

Jackie drives 160 miles from Gary, Indiana to Indianapolis, Indiana in 2.5 hours

Distance = 160 miles

Time = 2.5 hours

So , the speed = distance / time

Substituting the values in the equation , we get

Speed = 160 / 2.5

Speed = 64 miles / hour

Now , the new distance = 240 miles

So , the Time required = Distance / Speed

Substituting the values in the equation , we get

Time required A = 240 / 64

Time required A = 3.75 hours

Therefore , the value of A is 3.75 hours

Hence , the time taken with a speed of 64 mph is 3.75 hours

x = 5/8

Step-by-step explanation:

x - 1/4 = 3/8

Add 1/4 to both sides.

x - 1/4 + 1/4 = 3/8 + 1/4

x = 3/8 + 2/8

x = 5/8

Answer:

4x-15

Step-by-step explanation:

5(x-3)-x

first we want to distribute 5 to x and -3

5xx=5x 5x-3=-15

now we have

5x-15 - x

then we just have to combine like terms and the only alike terms are 5x and -x

5x-x=4x

so the answer is 4x-15

Answer:

5x-15-x

Answer:

B is the answer

Step-by-step explanation:

The transformation is a reflection across the y axis and you can see that they are congruent because the points are exact mirrored images.

To answer this question we're going to need to use the distance formula, which is

d = √((x2 - x1)2 + (y2 - y1)2)

We are given two points:

(x1, y1) = (-2, 1)

(x2, y2) = (-5, 3)

d = √((-5 - (-2))2 + (3 - 1)2)

= √((-3)2 + (2)2)

= √(9 + 4)

= √(13)

≈ 3.6056

Since it says to round to the nearest tenth, the distance between the 2 points is

3.6 units

d=3.6
