Answer: B. 28.26 ft2
Step-by-step explanation: I did this in school and got it right.
The appropriate formula here is l = a + (n-1)d, where l represents the last term.
Here the first term is -5 and the common difference is +4. Thus,
l = -5 + (n-1)(4) (answer)
Check: we are given the arith sequence -5, -1, 3, 7. Does our formula correctly predict the 1st term? l = -5 + (1-1)(4) = > -5. Yes.
Does it correctly predict the 3rd term? l = -5 +(3-1)(4) => -5+2(4) = 3. Yes
Answer:
You can rightly guess that ballistic motion is described by a quadratic function.
Differences of the y-values are 5.75, 3.25, 0.75, -1.75, -4.25.
First differences are not constant but form a linear sequence that decreases by 2.5 between each pair. Since second differences are constant, the function is described by a 2nd-degree polynomial function, a quadratic.
Answer:
6 s^9 t^3
Step-by-step explanation:
When you multiply same variables with exponents, you want to add the expoenents.
6s^5t * s^4t^2
s^5 * s^4 = s^9
t * t^2 = t^3
6 * 1 = 6
6 s^9 t^3
