Answer:
=760 ft
Step-by-step explanation:
h=16t^2+126t
Let t=4
h = 16 (4)^2 +126(4)
h = 16*16 +126(4)
=256+504
=760 ft
Part 1: Answer:
(x+1)(x+1)(x-6) = x^3 - 4x^2 - 11x - 6
Step-by-step explanation:
To make r a root, include (x-r) as a factor. (-1+1)(-1+1)(-1-6) is zero even though (-1-6) isn't.
(6+1)(6+1)(6-6) is zero.
Part 2 Answer:
Standard form: y = -x^4 + 12
Degree 4
left end goes down, right end goes down.
Step by step: apply the definitions of standard form, polynomial degree, and "end behavior". In other words, read the textbook.
Part 3: Answer: x = 3, x = 8
Step by step:
x^2-11x = -24
x^2-11x+24 = 0
(x-3)(x-8) = 0
x = 3 or x = 8
Part 4a Answer:
quotient 2x^2 + x - 3
remainder 1
Step by step:
2x^2 + x - 3

Part 4b answer:
quotient 2x^2 - 6x + 2
remainder -20
Step by step: you have to know exactly what you are doing. Refer to textbook or Wikipedia.
dividend 2x^3 +14x^2 - 58x
divisor x+10
leading coefficient of divisor must be 1
write coefficients of dividend at top
write coefficients of dividend at left
| 2 14 -58 0
-10 | -20 60 -20
___________
| 2 -6 2 -20
Coefficients of quotient are 2 -6 2
Remainder is -20
quotient = 2x^2 - 6x + 2
Answer:
B yes, because every x value corresponds to exactly one y value
Step-by-step explanation:
A function means that each input goes to a different output
Each input goes to only 1 y value
Answer:
51 vreels
Step-by-step explanation:
Step 1: Given data
Ratio of gespils to vreels on the planet Joop: 6:14
Step 2: Calculate the number of gespils per 120 vreels
Elentine has 120 vreels on her rew farm. If there are 6 gespils every 14 vreels, the number of gespils is:
120 vreels × (6 gespils/14 vreels) ≈ 51 vreels
