1. The average rates of change found in Exercise 3 represent the average speed at which the rim of the tire is moving

towards or away from the street between two specific time intervals.

2. The instantaneous rate of change, which is typically found by taking the derivative of the function and evaluating it at the desired point (t=3 sec in this case).

In past mathematics classes, you may have encountered expression (1) in the context of finding the slope of a secant

1. The average rates of change found in Exercise 3 represent the average speed at which the rim of the tire is moving

towards or away from the street between two specific time intervals.

change over an interval of time rather than at a specific instant.

To find the exact rate at which the rim of the tire is

The percentage of young adults who exercised four or five days a week is 36%

Out of the 25 young adults surveyed, a total of 4 people exercised four days a week and 5 people exercised five days a week. To calculate the percentage of young adults who exercised four or five days a week, we add the number of people who exercised four days a week to the number of people who exercised five days a week, which gives us a total of 9.

We then divide this by the total number of people surveyed (25) and multiply by 100 to get the percentage.

Answer:

\(\$68\)

Step-by-step explanation:

1. Approach

To solve this problem, one wants to find the price of a product after its discount has been applied. The discount is 20% off, so the new price of the item is 80% of its original price (percent is out of 100 so if a an item is 20% off, it is 100 - 20 = 80; 80% the original price). To calculate the percent cost, one would divide the percent value by 100, and then multiply it by the price of the item.

2. Solving

The price of the new item is 80% of the price of the original item.  To calculate the percent cost, cent, one would divide the percent value by 100, and then multiply it by the price of the item.

Therefore, the equation that will be formed is,

\(price * \frac{percent}{100}\)

Substitute,

\(85 * \frac{80}{100}\)

Simplify,

\(85 * 0.8\\\\= 68\)

Answer:

Three less than 7 times a number is 39.

Step-by-step explanation:

Using linear approximation, the expression √125.2 can be approximated as approximately 10.02.

To find the equation of the tangent line to the function f(x) = √x at x = 125, determine the slope (m) and the y-intercept (b) of the tangent line.

First, find the slope (m) using the derivative of the function f(x) = √x:

f'(x) = 1 / (2√x)

Evaluate the derivative at x = 125:

f'(125) = 1 / (2√125) = 1 / (2 × 5) = 1/10

Now, find the y-coordinate of the point on the function f(x) at x = 125:

f(125) = √125 = 5

So, the tangent line at x = 125 passes through the point (125, 5) and has a slope of 1/10.

Using the point-slope form of a linear equation, the equation of the tangent line can be written as:

y - 5 = (1/10)(x - 125)

To simplify, multiply through by 10:

10y - 50 = x - 125

Rearranging the equation, express it in the form y = mx + b:

y = (1/10)x - 75/10 + 5

Simplifying further:

y = (1/10)x - 75/10 + 50/10

Combining the terms:

y = (1/10)x - 25/10

Therefore, the equation of the tangent line to f(x) = √x at x = 125 is y = (1/10)x - 25/10.

Now, use this tangent line to approximate the value of √125.2:

Substitute x = 125.2 into the equation:

y = (1/10)(125.2) - 25/10

y = 12.52 - 2.5

y ≈ 10.02

So, using linear approximation, approximate √125.2 as approximately 10.02.

Step-by-step explanation:

perimeter of rectangle=2(l+b)

=2(8+4)

Answer:

tbh idek wth that is

Step-by-step explanation:

The perimeter and area of a rectangle are (5,6) and (6,5).

The perimeter method for a rectangle states that P = (L + W) × 2, where P represents perimeter, L represents length, and W represents width. when you are given the size of a square form, you may simply plug within the values of L and W into the formula that allows you to clear up for the fringe.

A perimeter is a closed course that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional period. The perimeter of a circle or an ellipse is known as its circumference. Calculating the perimeter has several practical programs.

The perimeter P of a rectangle is given by means of the method, P=2l+2w, in which l is the period and w is the width of the rectangle. The place A of a rectangle is given with the aid of the components, A=lw, wherein l is the length and w is the width.

The perimeter of the rectangle:

P=2l+2w=22

divide 2 into both sides

l+w=11 -------------> (1)

w=11-l

Area of the rectangle:

l*w=30

l(11-l)=30

11l-l^2-30=0

l^2-11l+30=0

By factor method,

(l-5)(l-6)=0

l=5,6.

Substitute this value in w,

l=5 implies w=6

l=6 implies w=5

There we have two solutions.

The length and breadth of the rectangle is

Step-by-step explanation:

Answer:

\(1.3\cdot 10^3\text{ J}\)

Step-by-step explanation:

Power is defined by work over time. In physics, work can be defined as the energy transferred over from an applied force over some distance. As a formula:

\(W=Fd\), where F = force applied and d = distance that force is applied over.

*It is worth noting that F must be parallel to the distance travelled. If it is perpendicular, no work is done, and if it is at an angle, find the parallel component and use that for F.

In this case, the force applied must counter the force of gravity on Martha, which is given by \(F_g=mg\), where m = Martha's mass and g = gravitational constant 9.8 m/s/s. Therefore, \(F_g=75\cdot 9.8=735\text{ N}\). Since she raises her body 4.0 meters, the work done must be \(W=Fd=735\cdot 4=2940\text{ J}\).

Since power is equal to work over time and t = 2.3 seconds, we have:

\(\displaystyle P=\frac{W}{t}=\frac{2940}{2.3}=\boxed{1278\text{ J}}\approx \boxed{1.3\cdot 10^3\text{ J}}\) (to two significant figures)
