Choose the correct option and explain.
Remember: Take 20 brainly point but give me correct answer.​

Answers

Answer 1
the correct answer is C.
Answer 2

Step-by-step explanation:

π is an irrational number

Reason:-

π is defined as the ratio of the circumference of a circle to the diameter of the circle

⇛π = C/d

The diameter and the Circumference of a circle are incommensurable.i.e.there does not exist a common unit to measure that allows us to measure the both. If you measure accurately then atleast either C and d is irrational. So π is regarded as Irrational number.

The decimal expansion of π is non terminating and non recurring decimal.

22/7 is a rational number

22/7 = 3.142857142857...

It is a non terminating and recurring decimal

it is a rational number.

We know that

The decimal form of a rational number is either terminating or non terminating and recurring decimal.

The value of π is closely nearer to 22/7

π= 3.1415...

π≠22/7

We often take 22/7 as an approximate value of π

Answer: From the above given options option (c) {π is irrational and 22/7 is rational} is your correct statement.

The down payment is $2,175.00 and you (or your parents) have an average credit rating. How much interest is accrued after the first month? Credit New Car APR (%) Used Car APR (%) 5.40 Excellent 5.65 6.35 Good 5.95 16.30 6.90 Average 17.60 Fair 7.55 9.80 10.0 Poor​

Answers

Using simple interest, it is found that $97.06 of interest is accrued after the first month.

Simple Interest

Simple interest is used when there is a single compounding per time period.

The amount of interest after t years in is modeled by:

[tex]I(t) = Prt[/tex]

In which:

P is the principal.r is the interest rate, as a decimal.

In this problem, first we have to find the total price of purchase of the car, which is $19,725.00 plus 4.75% sales tax, hence:

[tex](1 + 0.0475) \times 19725 = 1.0475(19725) = 20662[/tex]

Then:

Considering a down payment of $2,175, the principal is of P = 20662 - 2175 = 18487.New car and average credit rating, hence the interest rate is of 6.30%, that is, r = 0.063.We want the interest earned after one month, considering the time is measured in years, we have that [tex]t = \frac{1}{12}[/tex].

Then:

[tex]I\left(\frac{1}{12}\right) = 18487(0.063)\frac{1}{12} = 97.06[/tex]

$97.06 of interest is accrued after the first month.

What is the lateral surface area of the square pyramid represented by this net?

Answers

Answer:

340 ft²

Step-by-step explanation:

From the diagram, we can see that the shape is made up of a square and 4 triangles. (We know it's a square as its width equals its length).

First, find the area of the square.

Area of a square = width x length = 10 x 10 = 100 ft²

All the triangles are the same, so we need to find the area of one of the triangles and multiply it by 4.

Area of a triangle = 1/2 x base x height = 1/2 x 10 x 12 = 60 ft²

So the total area of all 4 triangles = 4 x 60 = 240 ft²

Therefore the total surface area = 100 + 240 = 340 ft²

Answer:

340 ft²

Step-by-step explanation:

The surface area of a shape is basically the area of its faces.

[tex]\rightarrow \text{Surface area of pyramid: 4(Area of triangle) + Area of square}[/tex]

1. First, Let's find the area of the triangles. To find the area of a triangle, we need to multiply the height and the base and then divide the product by 2.

[tex]\rightarrow \text{Area of triangle} = \dfrac{12 \times 10}{2}[/tex]

Now, let's find the area of the triangle by simplifying the RHS.

[tex]\rightarrow \text{Area of triangle} = 6 \times 10[/tex]

[tex]\rightarrow \text{Area of triangle} = 60 \ \text{ft}^{2}[/tex]

Since there are four triangles, we need to further multiply the area of the triangle by 4 to find the area of four triangles.

[tex]\rightarrow \text{Area of four triangles} = 4(60)[/tex]

[tex]\rightarrow \text{Area of four triangles} = 240 \ \text{ft}^{2}[/tex]

2. Now, let's find the area of the square. To find the area of the square, we need to square the side length.

[tex]\rightarrow \text{Side length} = 10 \ \text{ft}[/tex]

[tex]\rightarrow \text{Area of square} = 10^{2}[/tex]

[tex]\rightarrow \text{Area of square} = 100 \ \text{ft}^{2}[/tex]

3. Lastly, let's find the surface area. To find the surface area of the figure, we need to sum up the area of the triangles and the area of the square.

[tex]\rightarrow \text{Surface area of pyramid: 4(Area of triangle) + Area of square}[/tex]

[tex]\rightarrow \text{Surface area of pyramid: 240 + 100}[/tex]

[tex]\rightarrow \text{Surface area of pyramid: 340 \text{ft}}^{2} }[/tex]

Write an equation for the line that is parallel to the given line and that passes through the given point.
y = 2/3x + 5 (-3, 8)

Answers

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

[tex]y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{2}{3}}x+5\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

so we're really looking for the equation of a line whose slope is 2/3 and passes through (-3 , 8)

[tex](\stackrel{x_1}{-3}~,~\stackrel{y_1}{8})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{\cfrac{2}{3}}(x-\stackrel{x_1}{(-3)}) \\\\\\ y-8=\cfrac{2}{3}(x+3)\implies y-8=\cfrac{2}{3}x+2\implies y=\cfrac{2}{3}x+10[/tex]

B. y=3x-10
c. y=2x+9x

e.y=x/3+10

Answers

Answer:

a. y = 3x² + 9x +6

d. y = x(3x + 10)

Step-by-step explanation:

Most equations that have a squared variable are going to be nonlinear.

If you distribute the x in the d equation you get this: y = 3x² + 10x

Choices b, c, and e are going to be linear because there is only one variable, and those variables do not have exponents.
