550n is the expression which shows the total calories for ‘n’ Big Macs.


The answer is 9350


Solution:

If there are 550 calories in a McDonald’s Big Mac, this means that there are 9350 calories in 17 Big Macs.

550 x 17 = number of calories in 17 Big Macs/ 9350 calories

Hopes this answers your question :)

Arrange the steps in the correct order to express cos3x in terms of cosx cos(2x)cos(x)-sin(2x)(x) [1-sin^2(x)]cos(x)-[2sin(x)cos
noname [10]

cos(3x) = cos(2x+x)

= cos(2x) cos (x) -sin(2x)sin(x)

=(1-2sin^2(x)) cos(x)-(2 sin(x) cos(x)) sin(x)

= cos x -2sin^2(x) cos(x) -2sin^2(x) cos(x)

= cos(x) - 4 sin^2(x) cos(x)

cos(x)(1-4sin^2(x))

=cos(x(1-4(1-cos^2(x))

=cos(x)(1-4+4cos^2(x))

= cos(x)-4cos(x)+4cos^3(x)

=-3cos(x)+4cos^3(x)

For how many minutes did Lynn run at a greater speed than Kael? 12 17 23 28.
Archy [21]

Answer:

<u><em>28 minutes.</em></u>

Step-by-step explanation:

We can see from our graph that 12 minutes after starting the race Lynn left Kael behind and he ran at a greater speed till the race ended after 40 minutes.

To find total number of minutes Lynn ran faster than Kael we will subtract 12 from 40.

Therefore, Lynn ran at a greater speed than Kael for <u><em>28 minutes.</em></u>
