Consider the function y = -2-3cos (x+pi). What effect does the -2 have on the basic graph

Mathematics

Elenna [48]3 years ago

ANSWER

-2 shift the graph of the basic function down by 2 units.

EXPLANATION

The given cosine function is:

y =  - 2 - 3 \cos(x + \pi)

This equation can be rewritten as:

y =  - 3 \cos(x + \pi)  +  - 2

We compare this to

y = a \cos(bx + c)  + d

The effect d has on the graph is that, it shifts the graph up by d units.

If d is negative the graph shifts down by d units.

Since d=-2, the graph will shift down by 2 units.

Answer:

I believe C is the line of best fit because everything is spread out more evenly instead of some being spread out farther than others.

CAN SOMEONE PLS HELP MEEEEEEE

Answer:

  1. 6x +y = -6
  2. 6x -y = 8
  3. 5x +y = 13

Step-by-step explanation:

To rewrite these equations from point-slope form to standard form, you can do the following:

  • eliminate parentheses
  • subtract the x-term
  • subtract the constant on the left
  • if the coefficient of x is negative, multiply by -1

Of course, any operation you do must be done <em>to both sides of the equation</em>.

__

1. y -6 = -6(x +2)

  y -6 = -6x -12 . . . . . eliminate parentheses

  6x +y -6 = -12 . . . . . add 6x

  6x +y = -6 . . . . . . . . add 6

__

2. y +2 = 6(x -1)

  y +2 = 6x -6

  -6x +y +2 = -6

  -6x +y = -8

  6x -y = 8 . . . . . . . . multiply by -1

__

3. y -3 = -5(x -2)

  y -3 = -5x +10

  5x +y -3 = 10

  5x +y = 13

_____

<em>Additional comment</em>

The "standard form" of a linear equation is ax+by=c for integers a, b, c. The leading coefficient (generally, 'a') should be positive, and all coefficients should be mutually prime (have no common factors). That is why we multiply by -1 in problem 2.

Rachel deposited $200 into an account that earns 6% interest compounded twice a year for 10 years
Tanya [424]
<span>In order to calculate compounded interest, we use the formula: Final amount = initial amount x (increase rate)^(time periods). We know that the interest rate is 6%, so the factor we multiply by is 1.06. Moreover, the interest is compounded twice per year. This means that there will a total of 2 x 10 = 20 time periods over which the amount is compounded. Therefore, the final amount works out to be: Final amount = 200(1.06)^20, which is equivalent to $641.</span>
