By using the concept of rate of change, it is obtained that

Water level is falling at the rate of [tex]\frac{2}{9\pi}[/tex] m per minute

What is rate of change?

Suppose there is a function and there are two quantities. If one quantity of a function changes, the rate at which other quantity of the function changes is called rate of change of a function.

Here the concept of rate of change has been used

Let the radius of cone at any point be r m and height be h m

Volume of cone = [tex]\frac{1}{3}\pi\times r^2\times h[/tex]

Now,

By the concept of similarity,

[tex]\frac{r}{h} = \frac{4}{16}\\\\\frac{r}{h} = \frac{1}{4}\\\\r = \frac{1}{4}h[/tex]

Volume of cone (V) =

[tex]\frac{1}{3}\times \pi \times (\frac{1}{4} h)^2\timesh\\\\\frac{1}{48}\times \pi \times h^3\\[/tex]

[tex]\frac{dV}{dt} = \frac{1}{48} \times \pi \times 3h^2\times \frac{dh}{dt}\\\\\frac{dV}{dt} = \frac{1}{16} \times \pi \times h^2\times \frac{dh}{dt}\\\\[/tex]

Now,

[tex]\frac{dV}{dt} = -2,\ h = 12[/tex]

So,

[tex]-2 = \frac{1}{16}\times \pi \times (12)^2 \times \frac{dh}{dt}\\\\\frac{dh}{dt} = -\frac{2 \times 16}{\pi \times 12 \times 12}\\\\\frac{dh}{dt} =- \frac{2}{9\pi}[/tex]

So water level is falling at the rate of [tex]\frac{2}{9\pi}[/tex] m per minute

In comparison to her classmates, Kay did better in quiz 2.

According to the question,

Kay scored 15 on Quiz 1 which had a mean of 12 and a standard deviation of 2.4

= Z-score = 15 - 12/ 2.4 = 1.25

She scored 14 on Quiz 2 which had a mean of 11 and a standard deviation of 2

= Z-score = 14 - 11/ 2 = 1.5

The 95% confidence interval for the average apple weight is (119.14, 125.86).

An apple typically weighs 120 grams with a 12-gram standard deviation, according to one manufacturer. The average weight of an apple was 122. 5 grams, according to statistics created from a sample of 49 apples that were randomly chosen from a shipment.

Let, n = 49

x = 122.5 

σ = 12

To calculate and interpret a 95% confidence interval for the average apple weight, use the formula;

⇒ (x ± 1.96*σ/√n)

⇒ (122.5 ± 1.96*12/√49)

⇒ (119.14, 125.86)

Consequently, the average apple weight has a 95% confidence interval of (119.14, 125.86).

As per the given ratio, the length of the actual counter is 120 feet.

Ratio:

Basically, the ratio refers an ordered pair of numbers a and b, written a / b where b does not equal 0. And a proportion is an equation in which two ratios are set equal to each other.

Given,

Gwen measured a kitchen and made a scale drawing. The scale she used was 11 inches : 5 feet.

Here we need to find the length of the actual counter if  a countertop in the kitchen is 22 inches long in the drawing.

While looking into the given question, we have identified the following things,

Scale drawing ratio = 11 inches : 5 feet

And the length of the drawing = 22 inches.

When we convert the inches into feet,

Then we get,

=> 11 inches = 11/12 feet.

So the actual length can be calculated as,

=>22 : 11/12 : 5

=> 22 x 12/11 x 5

=> 2 x 12 x 5

=> 120

Therefore, the length of the actual counter is 120 feet.

Answer:

Gretta will earn $617.50 interest

A = $7,117.50

Equation:

A = P(1 + rt)

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9.5%/100 = 0.095 per year.

Solving our equation:

A = 6500(1 + (0.095 × 1)) = 7117.5

A = $7,117.50

The total amount accrued, principal plus interest, from simple interest on a principal of $6,500.00 at a rate of 9.5% per year for 1 years is $7,117.50.

The values of the segments formed by the median lines in the triangles are;

1. KG = 22

2. [tex]\overline{JE}[/tex] = 19.5

3. FL = 11

9) CI = 4

10) XK = 4

14) x = 3

A median line of a triangle is a line drawn from a vertex of the triangle to the the middle of the of the opposite side, thereby bisecting the opposite side into two segments of the same length.

The median lines are; [tex]\overline{JE}[/tex], [tex]\overline{KF}[/tex], and [tex]\overline{LD}[/tex]

1. The length of [tex]\overline{GF}[/tex] = 11

The properties of a median line indicates;

[tex]\overline{GF}[/tex] = (1/3)·[tex]\overline{KF}[/tex]

Therefore;

11 = (1/3)·[tex]\overline{KF}[/tex]

[tex]\overline{KF}[/tex] = 3 × 11 = 33

[tex]\overline{KG}[/tex] = (2/3)×[tex]\overline{KF}[/tex]

Therefore;

[tex]\overline{KG}[/tex] = (2/3) × 33 = 22

[tex]\overline{KG}[/tex] = 22

2. [tex]\overline{JG}[/tex] = 13

[tex]\overline{JG}[/tex] = (2/3) × The median line [tex]\overline{JE}[/tex]

Therefore;

[tex]\overline{JG}[/tex] = (2/3) × [tex]\overline{JE}[/tex]

[tex]\overline{JE}[/tex] = (3/2) × [tex]\overline{JG}[/tex]

[tex]\overline{JE}[/tex] = (3/2) × 13 = 19.5

3. JL = 22

[tex]\overline{KF}[/tex] is a median line, therefore, the point F is the midpoint JL

JF = FL

JL = JF + FL by segment addition postulate

JL = FL + FL = 2·FL (substitution property of equality)

JL = 22 = 2·FL

FL = 22 ÷ 2 = 11

9) CS = 6

Where CS is a median line of the triangle ΔABC, then;

CI = (2/3) × CS

CI = (2/3) × 6 = 4

10) UX = 8

Where UX is a median of the triangle ΔTUX, we get;

XK = (1/3) × UK

UX = (2/3) × UK

UK = (3/2) × UX = (3/2) × 8 = 12

XK = (1/3) × 12 = 4XK = 4

14) KL = 7·x + 1

LE = 2·x + 5

The properties of median line indicates that, KL = (2/3)·KE

LE = (1/3)·KE

Therefore;

KL = 2 × LE

7·x + 1 = 2 × (2·x + 5) = 4·x + 10

7·x + 1 = 4·x + 10

If the x-intercepts are (5, 0) and (12, 0) then:

Substitute the values of p and q into the formula:

Area = Length × width

Here we have

Width of the rectangle = 3w² and

Length of the rectangle = 2w⁵

As we know the area of the rectangle = Length × width

Area of the rectangle, A = 3w² × 2w⁵
