40 apps.
Explanation:
60 divided by 12 is 5. That’s how many downloading sessions could fit in a minute. Multiply 5 by the number of apps, which is 8. Your answer is 40 apps.
Answer:
The answer is a. cos2x - sin2x - sin x. Use the rule: cos2x = (cos^2)x - (sin^2)x. So, substitute cos2x in the expression: cos2x - sinx = ((cos^2)x - (sin^2)x) - sinx = (cos^2)x - (sin^2)x - sinx. Therefore, choice a. is correct choice.
Generic exponential growth model: y = Ao[1+r]^t
In this case: r = 3.5% = 0.035
y = 2Ao .....[the double of the initial value]
Then: 2Ao =Ao (1 + 0.035)^t
(1.035)^t =2
Take logarithm to both sides
t ln(1.035) = ln(2)
t = ln(2) / ln(1.035) = 0.693 / 0.0344 = 20.15
Answer: 20.15 hours.
Let the number of packages of caps be x and the number of packages of shirts be y, then
3x = 45 => x = 45/3 = 15
5y = 45 => y = 45 / 5 = 9
