Answer:
Step-by-step explanation:
<em><u>The correct function is</u></em>
we have
System of equations
-----> equation A
-----> equation B
Solve by substitution method
substitute equation B in equation A
Solve for r
Divide by 7.188π both sides
square root both sides
0.59 increase because it went up
Combine like terms
-6x² + (-x²) = -6x² - x² = -7x²
-7x² + 15x + 4 is your answer
hope this helps
You have r^2 = 64 and want to find the square root of 64, which we'll call r.
√(r^2) = r = plus or minus √64
or: r = plus or minus 8
D. 4.81 x 10^13
Move the decimal to the right 13 times, because when you multiply by 10, you make the number bigger, when you divide you move the decimal to the left to make the number smaller.
