Step-by-step explanation:
ok so I'm going to try to show it the best c an
m = slope
the equation you use is
m
so when using that formula with the cords, you get

and then subtract everything and you'll get

Answer:
D
Step-by-step explanation:
This is exponential growth, and to my understanding, the format goes:
<em>initial amount (percent growth/ decay)^time</em>
percent growth = (<em>decimal percent + 1)</em>
<em>percent decay = (1 - decimal percent) </em>
Your equation:
1500(1.02)^t
Using the above format, 1500 appears to be the initial amount, which increases by 2% per annum.

Answer:
9 nickels
Step-by-step explanation:
Set the number of pennies as x. The number of nickels would be 31 - x.
The pennies are worth x cents and the nickels are worth 5 * (31 - x), or 155-5x.
We are given that he has 67 cents, so:
x + 155 - 5x = 67
Solve.
-4x = 67 - 155 = -88
x = 22
Nickels are 31 - x, so the number of nickels he has is 9.

Hey there! Hope I can help!
<span><span>P is the principal amount, $550.00.
</span><span>R is the interest rate, 3% per year, or in decimal form, 3/100 = 0.03.
</span><span>T is the time involved, 10 year(s) time period.
</span><span>So, t is the 10 year time period.
</span></span><span>To find the simple interest, we multiply 550 × 0.03 × 10 to get $165.00
</span>
<span>Then the interest is added onto the principal to figure the new amount after 10 years. </span>
<span>550.00 + 165.00 = 715.00 > $715.00 after 10 years.</span><span>
Hope this helps!
