The change in area is 0.8π [tex]m^{2}[/tex] and percentage is 20%.

What is change in area?

Let A denotes the area of the circle when its radius is r, then A=πr2 Now, the rate of change of the area with respect to its radius is given by, dA dr = d dr(πr2) = 2πr When r= 4cm,(dA dr)r=4= 2π(4) = 8π cm2 per cm Hence, the area of the circle is changing at the rate of 8πcm2/cm

Given,

initial radius = 2m

increased radius = 2.02 m

change in radius dr = 2.02 - 2 = 0.02m

Area = π[tex]r^{2}[/tex] = 4π

dA = 2πrdr

=2π(2)(0.02)

=0.08π [tex]m^{2}[/tex]

Estimated percentage = 0.08/4×100

=2%

Hence, the estimated percentage is 2%.

The estimate that best describes the area under the curve in square units is option B: 15 units².

The area under a curve in calculus is a picture of an integral. It is frequently possible to interpret the area under a curve as the total amount of whatever the function is describing.

By performing a definite integral between the two locations, one can determine the area under a curve between two points. Integrate y = f(x) between the limits of a and b to tell about the area under the curve y = f(x) between x = a & x = b.

Therefore, each box:

0.5 × 1 = 0.5 units^2.  Then add up the boxes, and it is about  30. So:

30×0.5 = 15 units².

The value of subtracting the expressions (4.97n − 3.6) − (3 + 15.6n) is -10.63n − 6.6

Expressions are mathematical statements that are represented by variables, coefficients and operators

The expression is given as

(4.97n − 3.6) − (3 + 15.6n)

Start by opening the brackets

So, we have

(4.97n − 3.6) − (3 + 15.6n) = 4.97n − 3.6 − 3 - 15.6n

Next, we collect the like terms

So, we have

(4.97n − 3.6) − (3 + 15.6n) = 4.97n  - 15.6n − 3.6 − 3

Next, we evaluate the like terms

So, we have

(4.97n − 3.6) − (3 + 15.6n) = -10.63n − 6.6

Hence, the value of the expression is -10.63n − 6.6

Distance was 10 miles away from home.

What is Distance ?

The measurement of distance is the separation between two objects or points, and it can be quantitative or occasionally qualitative. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.
For a journey to see her cousin, Hannah traveled. She traveled 120 miles one way to visit her cousin and 120 miles the other way to return home.

She traveled halfway to her cousin's home in 1.2 hours.
That is 120 / 2 = 60 miles
(Speed = distance/time) 60 miles in 1.2 hours
Average speed = 60 / 1.2

                          = 50 mph.

For the remainder of the journey to her cousin's home, Hanna's average speed was 40 miles per hour.
Another 60 kilometers remain: Time (= Distance/Speed)
Time = 60/40

         = 1.5 hours.

Hanna averaged 55 miles per hour when she made her way home along the same path. Her automobile broke down after two hours.

Find the distance traveled at 55 mph in 2 hours. (Distance = time * speed)

Distance = 55 * 2 = 110miles

So distance from home will be,

= 120 - 110

= 10 miles

Hence, she was 10miles away from her home

The probability that maximum speed differs from the mean value by at most 1.5 standard deviations is 0.1336.

The probability is typically defined as the proportion of positive outcomes to all outcomes in the sample space. It is written as, P(E) = (Number of favorable outcomes) = Probability of an Event (Sample space).

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

The probability will be illustrated as:

P(|Z|>1.5)

= P(Z<-1.5) + P(Z>1.5)

= 2*P(Z<-1.5)

If the steps are shaped like rectangular prism, then the expression that can be used to find the volume is option (B)  (6×16×6)+(14×16×7)

The steps are shaped like rectangular prism

The length of the rectangular prism = l×w×h

Where l is the length

w is the width

h is the height

First we have to separate the given steps in to two rectangular prism and find the volume of each prism

The volume of the top prism = l×w×h

= 6×16×6 cubic inches

The volume of the bottom prism = l×w×h

= 14×16×7 cubic inches

The total volume = (6×16×6)+(14×16×7) cubic inches

The 21-screen movie complex has  three types of movie theaters,

let the number of traditional movie viewing theater be  "a" ,

let the number of 3D movie viewing theater be  "b" ,

let the number of luxury movie viewing theater be  "c" ,

So , a+b+c=21      ...(i)

given that ,

Traditional viewing theaters are twice of the combined number of 3D and luxury theaters ,

So the equation is

a=2(b+c)         ...(ii)

The value of X and Y in the length of each side of an equilateral triangle is X = 3 and Y = 4

In this question we have been given the equations for the three sides of an equilateral triangle.

3X +12, 8X -3 and 5Y + 1

We need to find the value of X and Y.

We know that all sides of an equilateral triangle are equal.

so, 3X +12 = 8X -3 = 5Y + 1

Consider 3X +12 = 8X -3

3X -8X = - 3 - 12

-5X = - 15

X = 3

Now consider an equation 8X - 3 = 5Y + 1

substitute above value of X in this equation.

8(3) -3 = 5Y + 1

24 - 3 = 5Y + 1

21 - 1 = 5Y

5Y = 20

Y = 4

Each member of the club needs to pay £ 4.895 to cover the cost of hiring the buses.

A youth club's 143 members and eight leaders ride a bus to a bowling alley.

The buses for hire by the beezer bus company hold 32 passengers each.

The cost of each bus to hire is £140.

There are eight leaders and 143 members.

Therefore, there are a total of 143 + 8 = 151 passengers.

So, the number of buses required will be:

= 151 / 32 =  4.7 ≈ 5 buses

Therefore, the cost of hiring 5 buses will be:

= 5 × £140 = £ 700

As the eight leaders will not ay.

Therefore, the amount each member needs to pay is:

= £ 700 / 143

The remainder when [tex]5^{400}[/tex] is divided by 19, the remainder is 17.

Remainder

The Remainder is the value left after the division. If a number (dividend) is not completely divisible by another number (divisor) then we are left with a value once the division is done. This value is called the remainder.

We can write,

[tex]5^{400} = (5^4)^{100} = 625^{100}[/tex]

We know that,

19*33 = 627

Hence, we can write 625 as 627 - 2

It will become,

[tex]\frac{(627-2)^{100}}{19}=\frac{(-2)^{100}}{19}[/tex]

We know that, even power of any number and its negative counterpart will be same.

Hence, we can write,

[tex]\frac{(-2)^{100}}{19}=\frac{(2)^{100}}{19} = \frac{2*2^{99}}{19}[/tex]

We know that 99 = 11*9

Hence, we can write,

[tex]\frac{2*({2^9})^{11}}{19} =\frac{2*512^{11}}{19}[/tex]

We know that,

19*27 = 513

Hence, we can write, 512 as 513 - 1

[tex]\frac{2*(513-1)^{11}}{19}=\frac{2(-1)^{11}}{19}[/tex]

2*(-1)/19 = -2/19
