The perimeter of a rectangle can be calculated using the following formula:

Where

"w" represents the width of the rectangle

"l" represents the length of the rectangle

If you know the perimeter and length of a rectangle, you can use the formula to determine the width. The first step is to write the formula for the width:

-Pass 2l to the left side of the expression by applying the opposite operation to both sides of it:

-Divide both sides by 2

Now that we have determined a formula for w, replace the value of the length and perimeter and calculate the width:

P=84in

l=28in

The width of the rectangular frame is 14 inches long

Applying the definition of the midpoint of a line and other properties, the proof that shows that AC ≅ CD is shown in the image attached below.

A line is divided into two equal parts by its midpoint. Thus, the midpoint of that line is that point where the line segment is bisected into two parts that are equal.

Given the image showing two lines that intersect each other at point C, the proof below shows that AC is congruent to CD:

1. C is the midpoint of line AE

C is the midpoint of line BD

AE is congruent to BD

(Reason: Given)

2. AC = CE; BC = CD

(Reason: Definition of midpoints)

3. AE = BD

(Reason: Definition of congruent segments)

4. AE = AC + CE;

BD = BC + CD

(Reason: Segment addition property)

5. AC + CE = BC + CD

(Reason: substitution property)

6. AC + AC = BC + BC

(Reason: substitution property)

7. 2AC = 2BC

(Reason: Simplify)

8. AC = CD

(Reason: division property)

9. AC ≅ CD

(Reason: definition of congruent segments).

The constant of proportionality in the equation y=1.5x is 1.5 .

The Constant Of Proportionality(k) in the equation can be defined as the constant value of the ratio between the two proportional quantities .

In Direct proportionality y=kx , where k is the constant of proportionality

means that if x increases then y also increases at the same rate ,

and if x decreases then y also decreases at the same rate .

For Example : constant of proportionality in y=6x , will be 6 .

In the question ,

it is given that

The monthly payment when you want to buy a 28,000 car is $567.

It should be noted that when the 10% down payment is made, the amount left will be:

= $28000 - (10% × $28000)

= $28000 - $2800

= $25200

The interest will be:

= PRT / 100

P = $25200

R = 2%

T = 48 months = 4 years

Interest = (25200 × 2 × 4)/100

= $2016

Total amount to be paid:

= $25200 + $2016

= $27216

The monthly payment will be:

= Amount / 48 months

= $27216 / 48

= $567

The monthly payment is $567.

Step-by-step explanation:

Hence the equation of the parabola is y = -x² + 4

In mathematics, a parabola is a roughly U-shaped, mirror-symmetrical planar curve. The same curves can be defined by a number of seemingly unrelated mathematical definitions, which all correspond to it.

The general equation of a parabola is given by y = ax² + bx+ c

The parabola passes through (-3,-5) , (-1,3) , and (0,4).

Now substituting the values in the parabola we get :

-5 =  a(-3)² + b(-3)+ c

or , -5 = 9a -3b + c

again:

3 = a(-1)² + b(-1)+ c

or, 3 = a -b + c

again

4 = a(0)² + b(0)+ c

or, c =4

Solving the equation we get :

9a - 3b = -9 and a-b = -1

a= -1 and b = 0

Hence the equation of the parabola is

y = -x² + 4

Answer:

h= 6

Step-by-step explanation:

To find out the value of h, start by forming an equation for the cost of renting a trampoline:

Cost of renting= $(75 +8t), where t is the rental duration.

When the cost is $125,

75 +8t= 125

Subtract 75 from both sides:

8t= 125 -75

8t= 50

Divide both sides by 8:

t= 50 ÷8

t= 6.25

Since she wants to spend less than $125, let's round the value down to the nearest hour.

∴ h= 6

Thus, she could rent it for 6 hours.

Let's check!

Total cost of renting for 6 hours

= 6(8) +75

= $123

Total cost of renting for 7 hours

= 7(8) +75

= $131

Hence, 6 hours is indeed the maximum number of hours she can rent the trampoline for, such that the total cost is less than $125.

Using combinations, we concluded that  the probability that fewer than 2 of the next 5 vehicles are from out of state is 0.907.

A checkpoint sees 75% of its traffic coming from within the state.

Therefore, there is a 0.75 percent chance that the car comes from the state.

1-0.75=0.25 represents the likelihood that the car is from outside the state.

Let x now act as the random variable. Consequently, n=9 and X=4

It is necessary to determine the likelihood that less than 2 of the following 5 automobiles are from another state.

We are to calculate the probability of x<2

p=0.25

q=0.75.

Using the formula,

P(x≤2) = ∑ ⁿCₓ pˣ q⁽ⁿ⁻ˣ⁾

P(x≤2) = ∑ ⁵C₂ p² q³ + ⁵C₁ p¹ q⁴ +  ⁵C₀ p⁰ q⁵

P(x≤2) = ∑ [tex]\frac{5!}{2! 3!}[/tex] (0.25)² (0.75)³ + [tex]\frac{5!}{1! 4!}[/tex] (0.25)¹ (0.75)⁴ + [tex]\frac{5!}{0! 5!}[/tex] (0.75)⁵

P(x≤2) = 10 × 0.065 × 0.421875 + 5 × 0.25 × 0.3164 + 0.2373

P(x≤2) = 0.2742 + 0.3955 + 0.2373

Therefore since we are given the value of p as 220. This will be:

m=2p - 0.75p - 50

m = 2(220) - 0.75(220) - 50

m = 440 - 165 - 50

What is Modulus of a number and ascending order?

Modulus of a number returns the absolute value of the number.

Modulus of positive number is positive and modulus of negative number is also positive.

If the numbers in a series are arranged in increasing order of their value, then the series is arranged in ascending order

Here,

|-35| = 35

18 = 18

|0.58| = 0.58

As, 0.58, 18, 35 is in ascending order,

Solve for n, using inverse operations to solve equations:

Step-by-step explanation:

it is just a matter of definition that can be easily looked up.

the domain is the interval or set of all valid x values.

while the range is the interval or set of all valid y (function result) values.

so, the domain here is every value of x used in this function.

e.g. does x = -6 have a functional (y) value in the curve ?

no, it does not.

x = - 4 ? no.

x = -2 ? no.

x = -1 ? ah, yes, this is just the left-most point of the curve.

and then all x values further to the right of -1 are covered. as the arrows indicate : into all eternity ("to infinity and beyond !")

so, the domain is [-1, +infinity).

and you need to use B.

please note, the round bracket indicates that that ends of the interval is not included or undefined (after all, infinity is not a number we can work with, it is basically undefined and only represents a principle).

for the range this is tricky, as the graph does not really show us the limit. it could be y = -1 or 0 down to y = -9 or -10.

The 15C3 represents the number of ways to pick the three people on the committee, while 15C12 is the number of ways to not pick a person for the committee. We can think of it like two separate committees if you want.
