2.1 ÷ 1.488 = 1.41
1.41 rounded to the nearest tenth is 1.4
so your answer is 1.4
Hey there :) You'll have to use the formula of cylinder to get your answer :
Surface area of cylinder : 2(pi)(r^2) + 2(pi)(r)(h)
pi = 22.7 or 22/7
r (radius of cylinder) = 8 mm
h = height of cylinder = 20mm
●Hence, just substitute your answer in the given formula and also don't forget to check whether the answer required needs to be in mm or cm.
Hope it helps :)
Im only doing this for. Points so id say probably around at least 5
For this case we have the following functions:

The first thing we must do for this case is to subtract both functions.
We have then:

Substituting we have:

Rewriting we have:

Evaluating the obtained function for x = 3 we have:

Answer:
The value of the function evaluated at x = 3 is:

I will do number 1 only. You can then use my solution steps to do the rest.
Solve 4x + 5 > 5x − 2 for x.
4x + 5 > 5x − 2
4x - 5x > - 2 - 5
-x > -7
Dividing both sides by a negative number reverses the inequality sign. In other words, the sign > becomes < in the reply.
-x/-1 < -7/-1
x < 7
Answer: x < 7
The answer here means that whatever the value of x is for question 1, it must be less than 7.
You finish.
