What is the surface area?​

Answers

Answer:

The total area is 685

Step-by-step explanation:

First get the area of the square; the area of the square is the height times the width. Because its a square all of its sides are equal, 15 times 15 equals 225. Next we go to figuring out the triangles´ area; the formula to figure out a triangles area is 0.5 times height times width. Because there are 4 of the exact same triangles we only have to figure out one and we have the area for each of them. 0.5 times 20 times 15 equals 115, with that information we are able to obtain all the information we need to discover the total area.

The area of the square: 225

The area of each of the triangles: 115

If there are 4 exact triangles of 115 then that equals all the triangles together to be 460, then add the square 460 plus 225 equals 685.

The scatter plot shows the number of hours worked and money soent on etnertainment by each of 25 students . Also shown is tbe ljne of best fit for the data fill in the blanks below

Answers

Answer:

Follows are the responses to the given question:

Step-by-step explanation:

Please find the attached file for the complete question:

For point A:

The amount of money being spent appears to rise for those 25 students as the number of hours increases. This is evident from the plot of scattering as well as the best line.

For point B:

Its number of hours spent as well as the amount of money spent were also positive for such 25 students.

For point C:

Also with a line that fits best, we will indeed predict that only an 8-hour student would spend about $22.

All these are seen in a direct line drawn from the x-axis where x=8 fits this same best line and a horizontal line is drawn between that axis and the Y-axis is drawn.

What is the equation of the line that passes through the point (2,-4) and has a
slope of 2?

Answers

i think it’s -2 but im not entirely sure

Answer:

y = 2x - 8

Step-by-step explanation:

Point(2 , -4) ; slope = 2

Point- slope form:

y - y1 = m(x - x1)

y - [-4] = 2(x - 2)

y + 4 = 2x - 2*2

y + 4 = 2x - 4

     y= 2x - 4 - 4

     y = 2x - 8

Answer:

[tex]x = \frac{-5\pm\sqrt{13}}{2}[/tex]

Step-by-step explanation:

Hello!

We can solve the quadratic by using the Quadratic Formula.

Standard form of a Quadratic: [tex]ax^2 + bx +c= 0[/tex]

Quadratic Formula: [tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}[/tex]

Given our equation: [tex]x^2+5x+3 = 0[/tex]

a = 1b = 5c = 3

Plug it into the formula and solve:

[tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}[/tex][tex]x = \frac{-5\pm\sqrt{5^2 - 4(1)(3)}}{2(1)}[/tex][tex]x = \frac{-5\pm\sqrt{25-12}}{2}[/tex][tex]x = \frac{-5\pm\sqrt{13}}{2}[/tex]

This cannot be simplified further. The answer is [tex]x = \frac{-5\pm\sqrt{13}}{2}[/tex].

We know there are two types of radicals one is surds when the number has been raised by such power that it is greater than zero and less than one,

The other type of radicals are indices where a number is raised to such power that is greater than one.

We know, √400 is 20.

Given, We have to find an irrational number between 19 and 20.

Now, From the given options the closest number to √400 is √402 but it is not between 19 and 20.

Therefore, The number whose square root is between 19 and 20 is,

write an equation for a function that has vertical asymptotes at x=3 & x=-10

Answers

Answer:

[tex] \frac{5}{ {x}^{2} + 7x - 30} [/tex]

Step-by-step explanation:

We can write a rational function.

We need to make sure our denominator both have zeroes at 3 and 10.

Set an equation equal to zero to find the function

[tex]0 - x = 3[/tex]

[tex]0 - x = - 10[/tex]

[tex]0 - ( - 3) = = 3[/tex]

[tex]0 - 10 = 10[/tex]

So we would represent that's as

[tex]x - 3[/tex]

and

[tex]x + 10[/tex]

Multiply the two binomial together.

[tex](x - 3)(x + 10) = {x}^{2} + 7x - 30[/tex]

Let our numbetator be any interger.

Use any equation as long as the quadratic is the denominator and the interger is the numerator.

[tex] \frac{5}{ {x}^{2} + 7x - 30 } [/tex]

You invest $500 in an account that pays 6% interest compounded continuously. How
much will be in the account after 6 years?

Answers

Answer:  716.66 dollars

=====================================================

Explanation:

We'll apply this formula

A = P*e^(r*t)

where,

A = account balance after t yearsP = initial deposit, aka principale = special constant roughly equal to 2.718 but it goes on forever without a pattern; it's better to let the calculator handle this value rather than type the decimal digits in.r = annual interest rate in decimal formt = number of years

In this case, we have

P = 500r = 0.06t = 6

Again we won't type "2.718..." for 'e', and we'll just type it into the calculator as shown below. That way the calculator can handle the digits instead.

So...

A = P*e^(r*t)

A = 500*e^(0.06*6)

A = 716.66470728026

A = 716.66 dollars is the final answer

y = 2(x − 2)2 + 5
y = 2(x2 − 4x + 4) + 5
y = 2x2 − 8x + 8 + 5
y = 2x2 − 8x + 13


answer choices


No. The error is in the second line: the expanded form of (x − 2)2 is x2 − 4.

No. The error is in the third line: the product of 2 and x2 − 4x + 4 is 2x2 − 4x + 4.

No. The error is in the fourth line: the sum of 8 and 5 is 12.
