Answer:
4262
Step-by-step explanation:
2 + 7x^2- 2x^3-8x +7x^4 at x = 5
= 2 + 7*(5)^2 - 2*(5)^3-8*5 +7*(5)^4
=2+175-250-40+4375
=4552-290
=4262

Answer:
n = 1
Step-by-step explanation:
First, rearrange the equation to standard form 0 = ax² + bx + c, when everything equals 0.
5n² = 5
5n² - 5 = 0
State the variables a, b and c.
a = 5; b = 0; c = -5
Substitute a, b, and c into the quadratic formula.
Substitute
Simplify inside the √ and bottom
Simplify the top
Final answer
Therefore the solution is n = 1.
The quadratic formula usually is written with x, but it can be solved with any variable in standard form.
Answer: $1690
Step-by-step explanation: because there are 3 people which means the flat fee would add up to 90 (because 30x3=90). Then you have to multiply 400 by 4 to get how much money they spent for renting the boat (400x4=1600). Lastly you add 1600 and 90 to get the final price. (1600+90=1690).
