Sorry guess I don’t know then

Answer:

B

Step-by-step explanation:

The y-intercept is 0,2 so that rules out C and D.

We then see that A cannot be true so it must be B.

Answer:

hi

Step-by-step explanation:

Let x = the length of the sides of the base and h = the height:

Volume = (area of base)(height)

V = x2h

2048 = x2h

2048/x2 = h

Surface Area = area of base + 4(area of vertical side)

SA = x2 + 4xh

Eliminate the h by using 2048/x2 = h:

SA = x2 + 4x(2048/x2)

SA = x2 + 8192 x-1

Take the derivative of SA wrt x, set it to zero, solve for x.  Plug that value of x into the surface area equation to find the minimum surface area.

Answer:

2.5%

Step-by-step explanation:

first things first youre gonna wanna BRING OUT THAT AWESOME CALCULATOR ok now:

enter 1 and then divide by sign, and then 40 and press Enter/equal sign.

we get:

0.025

BUT WAIT! we must multiply 0.025 by 100

we get 2.5%

Answer:

2.5%

Step-by-step explanation:

The fraction in question is 1/40, or 0.025.  The percent equivalent is found by multiplying this result by 100%:  

(100%)(0.025) = 2.5%

Answer:

9. r < -6

10. n > 7

11. x < -1

12. d > -4

13. m > 4

14. x < 3

15. d < ^-15/7

16. m > -6

Answer:

...

Step-by-step explanation:

So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.

845 = 45n + 125.

Subtract from both sides:

845-125 = 45n + 125-125

720 = 45n

Divide by 45:

720 / 45 = 45n / 45

16 = n

This means that 16 bracelets can be made if the cost is 845.

We can also re-input the information into the equation to be extra sure!

845 = 45 (16) + 125.

845 = 720 + 125.

845 = 845

Yes!

I hope this helps! :)

Answer:

45 x + 55 x = 350

x increases until the total equals 350

45 + 55 = 100 = relative speed of approach

(B) traveling cars meet this equation's specifications (x = 3.5)

The correct statement is option B)

Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time

Given here: The equation as 45x+55x=350

A car, traveling 45 mph, leaves Dallas heading for Odessa 350 miles away. At the same time, a truck leaves Odessa for Dallas traveling 55 mph on the same road.

Therefore the relative speed of the two trucks is given by 45+55=100

and let the time taken to meet is x then we can construct an equation as follows x=350/100

or,  45x+55x=350

Hence, The correct statement is option B)

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

Explanation:

The symbol that looks like an "E" is the uppercase greek letter sigma. It's used for summation. Specifically we are adding terms of the form -4+5n. What we do is replace n with values from the set {2,3,4,...,9,10}. After evaluating each item, we add up the results to get our final answer.

If n = 2, then -4+5n = -4+5*2 = 6 which is the first term.

If n = 3, then -4+5n = -4+5*3 = 11 is the second term

and so on until you reach n = 10.

A table is a handy way to keep track of everything (see below). Adding everything in the second column leads to the final answer of 234.

Answer:

Step-by-step explanation:

A parabolic graph with no real zeros never touches or crosses the x-axis.  

If the leading coefficient is negative, that tells us that the parabola opens down (and, in this case, that the entire graph is below the x-axis, because there are no real zeros.

If the y-intercept is odd, then the constant term, c, in ax^2 + bx + c, must be a negative, odd integer.

Suppose we say that the vertex of a particular parabola that is described by the above is (-2, -1) and that the y-intercept is -3.  (Note:  this is strictly an example.)  Then the vertex equation of this parabola is obtained from the general vertex equation of a parabola,

y = a(x - h)^2 + k.  Here h = -2 and k = -1, and so the particular parabola is

y = -a(x + 2)^2 - 1, where a is a constant and -a is negative.

In general form, this would be y = -a(x^2 + 4x + 4) - 1, or

                                                   y = -ax^2 - 4ax - 4a -1

and the constant terem (-4a -1) must be an odd negative integer

This is only one of an infinite number of possible equations for the parabola described above.

Step-by-step explanation:

23÷99=0.232323232

Since 0.232323232 is a repeating decimal with the 23 repeating, it can be represented as 0.23 with the line over 23
