Answer:
hey
please mark me brainliest
Step-by-step explanation:
f(x) = 0.69 (1.03)^x
in other words TO THE POWER x
that would be 0.69 when x = 0 years, now
0.69 * 1.03 after one year
0.69 * 1.03 *1.03 after two years
0.69 *1.03*1.03*1.03 after 3 etc
It is getting bigger. Every year you increase by .03 x which is 3%
Answer:
a)
b)
Step-by-step explanation:
a)
Assume that r is a regular price before discount and tax
Including discount, we substract 5 from r. We get (r-5).
Then, we include tax by adding 5% value of (r-5)
Including a tax we may realize by multiplying initial value (r-5) by 1.05, where an ending .05 is percentage value of a tax
b)
in a formula we substitute r=15.50 and calculate the value on the right side of the sign "=".
You solve it too, using a calculator.
If you push the following buttons:
1 5 . 5 0 - 5 = + 5 %
you should get a result 11.025, after approximation to the 2 digits after comma there is 11.03
Solve for b
<span>b² =81-36=45 </span>
<span>x²/a² - y²/b² =1 </span>
<span>plug in and choose</span>
First solve one of the two equations (whichever is easier) for either x or y, whichever variable is easier. Let's say you solved for x. Then plug what x equals into the 2nd equation as x. So if you got x = 2y + 1, plug that into your other equation and solve for y (you should get a number value).
Now take whatever y equals and plug that back into what you got when you solved for x (the x = 2y + 1) to get what x equals.
Answer:
As the study time increases the test score increases
Step-by-step explanation:
Nonlinear because the points aren't going in a straight line, they points fluctuate over time
