The perimeters of the given figures 4, 5, 6 are 27 m, 140.76 cm and 28 inches respectively.
We need to find the perimeter of given figures.
What is the perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.
4) Now, sum of all the sides
= 5+3.5+1.5+3.5+5+3.5+1.5+3.5 m
= 27 m
5) Here, radius = Diameter/2 = 17 cm
Perimeter = 2 semicircles+2(17) cm
= 2 × 1/2 πr + 2×17
= 2 × 3.14 × 17 + 34
= 140.76 cm
6) In the given figure here, there are 4 similar triangles
= 4(4+3) inches
= 4 × 7
= 28 inches
Therefore, the perimeters of the given figures 4, 5, 6 are 27 m, 140.76 cm and 28 inches respectively.

Jamie has a tabletop that he wants to cover with contact paper. The length, width, and height of the tabletop are 3.5 feet, 3.5 feet, and 0.25 feet, respectively. We need to calculate the area of the contact paper required to cover the entire tabletop.
Let the area of the tabletop be represented by the variable "A". We need to calculate the area of only the top surface of the table. The table is rectangular in shape. The area of the tabletop must be the product of the length and the width of the table.
A = 3.5×3.5
A = 12.25

An equation relating x and y is given by y = 3x/4 - 11/2.
How to calculate the slope of a line?Mathematically, the slope of any straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
For the slope of this line using point AB, we have:
Slope of AB = (2 - (-1))/10 - 6)
Slope of AB = (2 + 1)/4
Slope of AB = 3/4
Since point AB and points (2, -4), (x, y) all lie on the same straight line, they would all of the same slope. Therefore, an equation relating x and y can be calculated as follows:
3/4 = (y + 4)/(x - 2)
3(x - 2) = 4(y + 4)
3x - 6 = 4y + 16
4y = 3x - 6 - 16
4y = 3x - 22
y = 3x/4 - 22/4
y = 3x/4 - 11/2

The slope-intercept form of a straight line is:

A 850 kg car is moving with a speed of 10 m/s. Which of the following would cause the largest change in momentum?
a. Double the velocity and mass
b. Double the velocity and cut the mass in half
c. Keep the velocity the same and triple the mass
d. Cut the mass and velocity in half
Answers
The largest change in momentum will happen when the velocity and mass of the object are doubled( option A)
What is momentum?The momentum of a body is the product of the mass of the body and it's velocity. Momentum is measured in kg/ms^-1. It is a vector quantity. it is represented by p
Momentum of a body is expressed as p= m× v
where m is the mass of the body and v is it's velocity. This means that the higher the mass and velocity of the body the higher it's momentum.
The initial momentum of the body of mass 850kg and velocity 10ms^-1 = 850kgms^-1
When the velocity and mass are doubled , then the new momentum will be 1700× 20= 34000kgms^-1
Therefore the largest change in momentum will be obtained when both mass and velocity are doubled.

He rented the pressure washer for 4 hours, given that the total bill was $86.
An algebraic expression is the combination of numbers and variables in expressing and solving a particular mathematical question. An equation is the equality of expressions.
Let x = total number of hours he rented the pressure washer
The total bill, which was $86, includes the flat fee of $50 plus $9 per hour of use.
Hence, the equation will be 50 + 9x = 86.

Step-by-step explanation:
Here is the graph of the function:
The vertex is at (8, -2).
To plot another point on the parabola, we can choose any x-value and plug it into the equation to solve for y.
For example, if we choose x = 10, then we have:
f(x) = -5(x - 8)² - 2
f(10) = -5(10 - 8)² - 2
f(10) = -5(2)² - 2
f(10) = -5(4) - 2

Answers
The length, breadth and height will be 78 cm, 78cm, 78cm each.
let consider the length = l
breadth = b
height = h
we are provided that
l + b + h = 234cm .......(1)
Also we have to maximize the volume , provided length is equal to breadth
∴ eqn (1) becomes
2b + h = 234
h = 234 - 2b
also ,
volume(v) = lbh
v = b²(234 - 2b)
v = b²234 - 2b³
now to maximize the volume we take the first derivative of the volume wrt 'b' and place it equal to zero. ( lagrange method )
i.e. d( v)/db = 0
∴ 468b - 6b² = 0
6b² - 468b = 0
6b( b - 78 ) = 0
∴ b = 78 cm
now as length = breadth
l = b = 78 cm
also putting this value in eqn (1)
h = 234 - 2b
h = 78 cm
So , the dimensions will be equal and will be 78cm , 78cm, 78cm each .
