Answer:


Step-by-step explanation:

It may help you to think of this situation in this manner:

1.  The temperature drops 21 degrees from 21 degrees to zero degrees.

2.  The temp. then drops 3 degrees from zero to -3 degrees.

3.  The total change (which was a drop) was 21 + 3, or 24, degrees.

Summary:  from 21 degrees to -3 degrees is a change of 24 degrees.

More explicitly, that's a drop of 24 degrees.

How do i do this? Its confusing
cestrela7 [59]

Answer:

$12,415.48

Step-by-step explanation:

A = P (1 + r/n)^(nt)

where A is the final amount,

P is the initial amount,

r is the annual interest rate as a decimal,

n is the number of compoundings per year,

and t is the number of years.

A = 8000 (1 + 0.152/2)^(2×3)

A = 8000 (1.076)^6

A = 12415.48

Use synthetic division to find (x^2+3x–4)÷(x+4)
Jobisdone [24]

Answer:

X^2-x- 8/x+4

Step-by-step explanation:

X+4 becomes a negative 4

Then multiply -4 by the first number which is 1 so -4×1 is -4. Then subtract -4 by the second number 3. This gives you -1 so multiply that by 4 which is -4. Then subtract 4 from the third number -4. So that'll give you -8. Then add an x-value to every number except the very last number as that number will be you remainder.
