$\lim_{x \to 4} f(x)=x^2+3x-1$
just subsitute
f(4)=4²+3(4)-1
f(4)=16+12-1
f(4)=28-1
f(4)=27

it approaches 27 as x approaches 4

Total number of cubic inches of cheese sauce in container = Volume of cylinder = $\pi .8^2.7$

Option A is correct.

Step-by-step explanation:

The diameter of cylinder = 16 inches

The height of cylinder = 7 inches

Total number of cubic inches of cheese sauce in container = Volume of cylinder = ?

The formula used to find Volume of cylinder is:

$Volume=\pi r^2h$

We are given diameter of cylinder while we need radius according to formula.

So, radius = diameter/2

radius = 16/2

radius = 8

Putting values and finding volume:

$Volume=\pi .8^2.7$

So, Total number of cubic inches of cheese sauce in container = Volume of cylinder = $\pi .8^2.7$

Option A is correct.

Mark studies a group of 30 whales. If each whale weighed approximately 3.8 x 105 pounds, find the total weight of all 30 whales.

Yakvenalex [24]

Answer:

$= 1.14 \times 10^{7}pounds$

Step-by-step explanation:

If each whales weighed

$3.8 \times {10}^{5}$

Then 30 whales weighed

$30 \times 3.8 \times {10}^{5}$

$=114 \times {10}^{5}$

$= 1.14 \times 10^{2} \times {10}^{10}$

Applying the law of indices we obtain

$= 1.14 \times 10^{(2+ 5)}$

$=1.14 \times 10^{7}pounds$

How many ways can 6 people be chosen and arranged in straight line if there are 8 people to choose from? a. 48.b. 720.c. 20, 160

Ipatiy [6.2K]

Answer:

Step-by-step explanation:

This question bothers on permutation since we are to select a some people out of a group of people and then arrange in a straight line. If r object are to be arranged in a straight line when selecting them from n pool of objects. This can be done in nPr number of ways.

nPr = n!/(n-r)!

Selection of 6 people out of 8 people can therefore be done in 8C6 number of ways.

8P6 = 8!/(8-6)!

8P6 = 8!/2!

8P6 = 8*7*6*5*4*3*2!/2!

8P6 = 8*7*6*5*4*3

8P6 = 56*360

8P6 = 20,160

<em>Hence this can be done in 20,160 number of ways</em>
