Answer:
The Answer is C 252.48 horsepower
Step-by-step explanation:
To the get better understanding of answer above
First we have to understand that it is a rule of thumb that for every 1000 feet the horsepower reduces by 3 percent.
From the question the car horsepower is 300
3 percent of 300 is lost for 1000 feet
x percent of 300 is lost for 5280 feet
3 percent of 300 = (3 ÷ 100) × 300 =0.03
In term of the relationship between loss of horsepower and altitude
0.03 = 1000
x = 5280
cross multiply
= 252.48
Answer:
x > 15
Step-by-step explanation:
So here we have to find the value of x
So, Subtract 5 from both sides;
-10x < -5 - 145
Now collect like terms,
-10x < -150
Divide both sides by -10
x > 15
The sign changes because if an equality is divided by a negative number the sign automatically changes.
Answer: 7 9/20
Step-by-step explanation:
Add the two fractions together and In decimal form you will get 12.55. Simplify into fraction form and you get 7 9/20
Step-by-step explanation:
A Maclaurin series is a Taylor series that's centered at 0.
f(x) = ∑ₙ₌₀°° f⁽ⁿ⁾(0) / n! xⁿ
If we substitute f⁽ⁿ⁾(0) = (n + 1)!:
f(x) = ∑ₙ₌₀°° (n + 1)! / n! xⁿ
f(x) = ∑ₙ₌₀°° (n + 1) xⁿ
Use ratio test to find the radius of convergence.
lim(n→∞)│aₙ₊₁ / aₙ│< 1
lim(n→∞)│[(n + 2) xⁿ⁺¹] / [(n + 1) xⁿ]│< 1
lim(n→∞)│(n + 2) x / (n + 1)│< 1
│x│< 1
R = 1
Answer:
350 adult tickets were sold
Step-by-step explanation:
Let x represent the number of adult tickets sold.
Since there were 60 fewer student tickets sold than adult tickets, the number of student tickets sold can be represented by x - 60
Create an equation that sets up these terms equal to 640, then solve for x:
(x) + (x - 60) = 640
2x - 60 = 640
2x = 700
x = 350
So, 350 adult tickets were sold
