X If $7500 was compounded annually for 8 years at a rate of .23% how much will it be

Ann [662]

Answer:

$7639.12

Step-by-step explanation:

We use the compound formula for accrued value (A) for a principal P deposited at an annual rate "r" over t years

$A = P (1+r)^t$

In our case, with the given information, the formula becomes:

$A = P (1+r)^t\\A=7500 \,(1.0023)^8\\A = 7639.11602$

which rounded to the nearest cent gives: $7639.12

Find the slope of the line that passes through the points (3, 6) and (5, 3).

Temka [501]

(3,6) (5,3)
(x1,y1)(x2,y2)

The slope equation is: y2-y1
---------
x2-x1

Replace with numbers: 3-6/5-3

Minus 3 and 6 is equal to -3

Minus 5-3 is 2

So the fraction is -3/2 (no need to divide because you can't simplify it)

So the slope is -3/2

For the equation you have to replace the letters by 0's

3×0-2y=6
Times 3 and 0
0-2y=6
Now you want to get the y alone, so minus 0 from both sides
0-2y=6
-0 -0

-2y=6

Divide -2y from the 6

-2y=6
---- ---
-2 -2

y=3

The y intercept is 3 with the slope of -3/2

Write the product as the product of a whole number and unit fraction <br> 2x4/5=

Nimfa-mama [501]

Answer:

$1 \frac{3}{5}$

Step-by-step explanation:

The first step is to multiply the numbers of the numerator. Thus:

$\frac{2 \times 4}{5}$

$= \frac{8}{5}$

Writing the answer above as the product of a whole number and unit fraction (that is, mixed number), 5 goes in 8 1 time remainder 3. Therefore:

$= \frac{8}{5} = 1 \frac{3}{5}$

Each paper clip is 7/8 of an inch long and each cost $ 0.03 exactly enough paper clips are laid end to end to have a total lengt

cestrela7 [59]

To find the number of paperclips, divide 56 by 7/8 to give 64. Multiply this by 0.03 to give a total cost of $1.92

Identify the "inside function" u = f(x) and the "outside function" y = g(u). Then find dy/dx using the Chain Rule.

skad [1K]

DfLet $f(x)=\sec x$ and $g(x)=\sqrt x$ . Then

$y=\sec\sqrt x=\sec(g(x))=f(g(x))=f\circ g(x)$

By the chain rule,

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\mathrm dy}{\mathrm du}\dfrac{\mathrm du}{\mathrm dx}$

where $u=g(x)=\sqrt x$ , so that $y=f(g(x))=f(u)=\sec u$ . We have

$\dfrac{\mathrm du}{\mathrm dx}=\dfrac1{2\sqrt x}$
$\dfrac{\mathrm d\sec u}{\mathrm du}=\sec u\tan u$

and so

$\dfrac{\mathrm dy}{\mathrm dx}=\sec u\tan u\dfrac{\mathrm dy}{\mathrm du}=\dfrac{\sec\sqrt x\,\tan\sqrt x}{2\sqrt x}$
