Answers

Answer 1

only C) The diagonals bisect each other, and E) The diagonals are perpendicular are the two conditions that prove that a quadrilateral is a rectangle.

What is the quadrilateral?

A quadrilateral is a four-sided polygon, which means it has four straight edges and four angles. Quadrilaterals can come in many different shapes and sizes and can be classified based on their properties. Some common examples of quadrilaterals include squares, rectangles, parallelograms, rhombi, and trapezoids.

A quadrilateral is a rectangle if it satisfies the following conditions:

C) The diagonals bisect each other.

E) The diagonals are perpendicular.

A) Both pairs of opposite sides are congruent, is not a necessary condition for a quadrilateral to be a rectangle, as a rectangle can have different side lengths.

B) One pair of opposite sides is longer than the other pair of sides, is not a necessary condition for a quadrilateral to be a rectangle, as a rectangle can have equal side lengths.

D) The diagonals are congruent, is not a necessary condition for a quadrilateral to be a rectangle, as a rectangle can have diagonals of different lengths.

So, only C) The diagonals bisect each other, and E) The diagonals are perpendicular are the two conditions that prove that a quadrilateral is a rectangle.

What is the area of the square?

Remember that the area of a square of side length S is given by the formula:

A = S^2

Here we know that the side length is x - 8, then we can just replace that on the formula above to get:

A = (x - 8)^2

Now we can expand that:

A = (x - 8)^2 = (x - 8)*(x - 8)

Assume Florida has the same number of hospitals per million people as Texas.
Estimate the number of hospitals in Florida. Is this estimate close to the actual
number of hospitals in Florida in 2009?

Answers

In 2009, Florida would have 558 hospitals if it had the same hospital beds per million residents as Texas. This is a little more than what Florida's real number of hospitals was in 2009. (343).

What is logical proportionality?

A mathematical technique called proportional reasoning is used to compare the ratios of two or more identical quantities.

The proportionate reasoning theory is being used in this query.

In this instance, we're contrasting Florida's hospital density per million residents with Texas' hospital density per million residents.

We may predict the number of hospitals in Florida given the same ratio as Texas by comparing these two ratios.

1. Determine Texas's hospital density per million residents: 428 hospitals divided by 26.4 million residents equals 16.2 hospitals per million residents.

2. Determine Florida's hospital density per million residents: 343 hospitals / 19.5 million residents = 17.6 hospitals per million residents.

3. Multiply the population of Florida (19.5 million) by the number of hospitals per million of the population of Texas (16.2) to arrive at 315.3 hospitals: 19.5 million people x 16.2 hospitals per million of the population.

The result should be rounded to the next whole number: 315 hospitals are equal to 315.3 hospitals.

5. Contrast Florida's actual hospital count in 2009 with the expected number of hospitals there (315). (343).

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

Average rate of change of any function say S(x) on [a,b] is -

A = [S(b) - S(a)]/b-a....(1)

Now. for function f(x) on interval [4, 7].

Here, use values of f(4) and f(7) from graph and find value of f(x)=y for x=4 and value of f(x)=y for x=7.

f(4) = -10, f(7) = 5

Substitute the values in equation (1) -

A1 = [f(7) - f(4)]/(4 - 7)

A1 = [5 - (-10)]/-2

A1 = 15/-2

A1 = -7.5

Average rate of change for function g(x) on interval [4, 7].

Here, use the values of g(4) and g(7) from table.

g(4) = 7, g(7) = 19

Substitute the values in equation (1) -

A2 = [g(7) - g(4)]/(4 - 7)

A2 = [19 - 7]/-2

A2 = 12/-2

A2 = -6

Average rate of change for function h(x) = x² - 9x + 5 on interval [4, 7].

Here, use the values of h(4) and h(7) by putting x = 4 and x = 7 in function h(x).

h(4) = x² - 9x + 5

h(4) = (4)² - 9(4) + 5

h(4) = 16 - 36 + 5

h(4) = -15

h(7) = x² - 9x + 5

h(7) = (7)² - 9(7) + 5

h(7) = 49 - 63 + 5

h(7) = -9

Substitute the values in equation (1) -

A3 = [h(7) - h(4)]/(4 - 7)

A3 = [-9 - (-15)]/-2

A3 = [-9 + 15]/-2

A3 = 6/-2

A3 = -3

Now, average rate of change of these function f(x), g(x), h(x) from least to greatest is f(x)<g(x)<h(x).

jeremy is looking for a good auto loan in his city. He is willing to pay no more than an effective rate of 7.000% annually. which if any of the following loans meet jermeys criteria?
loan A : 6.785% normal rate compounded semi annually
loan B : 6.795% nominal rate compounded, manually
loan C : 6.659% nominal rate, compounded weekly.

Answers

Answer: To determine which loan(s) meet Jeremy's criteria of no more than an effective rate of 7.000% annually, we need to calculate the effective rate for each loan.

The effective rate is the true annual interest rate that a borrower will pay on a loan, taking into account the frequency of compounding.

Loan A: 6.785% normal rate compounded semi-annually

To calculate the effective rate, we can use the formula:

(1+ (nominal rate/2))^2 - 1

Effective rate = (1+ (6.785/2))^2 - 1 = 6.897%

Loan B: 6.795% nominal rate compounded, manually

Since the loan is compounded manually, the effective rate is the same as the nominal rate.

Effective rate = 6.795%

Loan C: 6.659% nominal rate, compounded weekly

To calculate the effective rate, we can use the formula:

(1+ (nominal rate/number of compounding periods per year))^(number of compounding periods per year) - 1

Effective rate = (1+ (6.659/52))^52 - 1 = 6.759%

Since 6.897% > 7.000% and 6.795% > 7.000% and 6.759% < 7.000%. So Loan C with 6.659% nominal rate, compounded weekly meets Jeremy's criteria.

Step-by-step explanation:

The number of employees for a certain company has been decreasing each year by 8%. If the company currently has 630 employees and this rate continues, find the number of employees in 13 years.​

Given

Number of employee in the company=630

Decreasing rate in the company per year =8%

Let the number left in the company be x

Since the decrease rate is 8% we use 0.08

So after 13 years the employee left are

630(1-0.08)¹³=x

630(0.92)¹³=x

630*.338= 212.94

We can take approx as 213

so x= 213

So 213 employees left in the company after 13 years.

Answers

Answer: Based on the information provided, it appears that the graph represents a linear equation, which is a straight line. The equation of a straight line can be represented in the form y = mx + b, where m is the slope of the line and b is the y-intercept.

To find the equation of the line, we need two points on the line. We can use the points (x1, y1) and (x2, y2) to calculate the slope of the line, m, using the formula:

m = (y2 - y1) / (x2 - x1)

Without knowing the coordinates of the points on the graph it is not possible to give the equation of the line.

To find the cost of ordering 6 pounds of mushrooms, we would substitute 6 for x in the equation of the line and solve for y.

y = mx + b

y = m(6) + b

Without the equation of the line, it's not possible to find the cost of ordering 6 pounds of mushrooms.

Answers

Christian is making a circular pizza. The diameter of the pizza is 12 inches. The pizza crust on the outside will be about 12 inches thick.

How is the pizza's circumference determined using this formula?

The formula for determining a pizza's circumference is C = 2πr, where C is the circumference, pi is a constant that is roughly equivalent to 3.14, and r is the pizza's radius.

We must determine the pizza's circumference in order to locate the crust on the pizza's outer edge. C = 2πr is the formula for a circle's circumference, where C is the circumference, pi is a constant that is roughly equivalent to 3.14, and r is the circle's radius.

The pizza has a diameter of 12 inches, so the radius, or 6 inches, is half of that. Thus, the pizza's circumference is:

                 C= 2π6 = 12π

The pizza's circumference represents the crust's outer edge. C = 26 inches = 12 inches As a result, the pizza's crust on the outside measures about 12 inches.

The incenter of a triangle can be discovered by drawing the triangle's angle bisectors and then locating the location of their intersection. This is possible with the aid of a compass.

The three line segments and the three lines that include those segments are equally spaced from the incenter and constitute each of the three sides of the triangle.

the single point where the three internal angle bisectors of a triangle meet and which also serves as the circumference of the circle around which it is inscribed.

The three line segments and the three lines that include those segments are equally spaced from the incenter and constitute each of the three sides of the triangle.  

ΔQUT is right triangle

QU = 55

UT= 17

Using Pythagoras Theorem

QT² = QU² + UT²

QT² = 55² + 17²

QT = √3314

QT = 57.56

Thus, The length of Mid segment QT is 57.56 units.

Amelia grabbed 50% of the M&M's from a bowl. Then, Jess took 50% of what was left. Dominick takes 50% of the remaining M&M's. There were 3 left. How many M&M's were in the bowl before Amelia arrived.

Answers

The number of M&M's that were in the bowl before Amelia arrived is; 12

How to solve Percentage problems?

Let the original amount in the bowl be x. Thus;

If Amelia grabbed 50%, then amount left = (100% - 50%)x = 50%x = 0.5x

Now, we are told that domicick took 50% of what was keft after amelia. Thus; New amount left = 100%x - (0.5x + 0.25x) = 0.25x

Now, we are told that there were finally 3 left after all the deductions. Thus;

0.25x = 3

x = 3/0.25

x = 12
