1 answer:

4 0

$f(x)=-5x^2-2x+20\\\\f(3)\to\text{put x=3 to the equation of the function f}\\\\f(3)=-5(3^2)-2(3)+20=-5(9)-6+20=-45-6+20=-31\\\\Answer:\ f(3)=-31$

Roberto, Christopher, and Levi are amateur cyclist riding in the 165.1 km long Tour of Cortez bicycle race. Each cyclist is indi

Naddik [55]

Answer:

Levi
Christopher
Roberto

Step-by-step explanation:

I like to work problems involving repetitive calculations using a spreadsheet. The sort function can easily put the results in the appropriate order.

Here, we need to compute minutes and kilometers remaining for each cyclist, and then divide the former by the latter to find the required timing.

Minutes remaining will be the difference between the qualifying time and the time used so far.

Km remaining will be the difference between the race length and the distance traveled so far.

Required minutes per km will be the ratio of minutes remaining to km remaining.

Levi has the least allowed minutes per km for his remaining distance. Roberto has the most.

_____

Christopher only has to increase his average speed by about 5% in order to qualify; Levi has the greatest challenge, as he needs about 18% more speed for the rest of the race.

12=-4(-6x-3)+2x work it out for me and tell me how many solutions

aev [14]

<span>12 = -4(-6x - 3) + 2x

Distribute the -4 on the right side.

12 = 24x + 12 + 2x

Combine like terms on the right side.

12 = 26x + 12

Subtract 12 from both sides.

0 = 26x

Divide both sides by 26

0 = x

Switch sides.

x = 0

There is one solution.

Is the square root of infinity still infinity?

Jet001 [13]

Infinity isn't actually a number - it's a concept that represents that the set of numbers goes on forever. As a result, you can't take the square root of infinity. However, you could state that as x approaches infinity (or rather, increase indefinitely), the square root of x also approaches infinity (again, increases indefinitely).
