Answer: The correct answer would be choice D, as long as the t was an exponent.
It should be written as 233.10 = 102.15(1.086)^t
The t has to be an exponent because you are multiplying the investment by 1.086 repeatedly each quarter. We used 1.086 because we added on 8.6% (or 0.086) to the investment.
<span>After substitution your equation should be:
0= -16t^2+135t+76 and your answer to {A} would be {135 goes as V, 76 goes as C}.
Question B is answered by soling the quadratic equation -16t^2+135t+76 = 0
Answer: 9.0s {the other solution is a negative }</span>
Answer:
I'll list the answers as coordinates (just input the second number in each coordinate)
(-2, 11)
(0, 1)
(2, -9)
(4, -19)
Step-by-step explanation:
So you see how the x column is filled out? You plug in the numbers in each area and solve for y.
So we start off with -2. You take the x out and place -2 instead. Your equation should look like this:
y = -5 (-2) + 1
Next you multiply -5 and -2, giving you 10. Your equation would look like this now:
y = 10 + 1
Next you add 10 and 1 together, and you have your answer. Keep doing the same thing, but instead of -2 for x, use 0, 2, and 4.
Hope I helped! Have a nice day or night! ^-^
No because some points can lie in the y & x-axises
