Answer:

Option A

Step-by-step explanation:

We have to find the limit of the function (x² + 3x - 1) as x approaches 3.

lim[f(x)] = lim (x² + 3x -1)

x⇒3         x⇒3

            = (3)² + (3 × 3) -1

            = 9 + 9 - 1

            = 18 - 1

            = 17

Option A is the answer.

A system of equations is given below.
MAVERICK [17]
First, solve the given system of linear equations.

Second, multiply the first equation by 4 (which was an arbitrary choice).  Add your result to the 2nd equation.

You should now have the following:

First equation:  No change:             <span>2x + 7y = 1

Second equation:  4(</span><span>-3x – 4y = 5) = -12x -16y = 20

Solve this new system of linear equations.  Do you (or do you not) obtain the same solution as your earlier one?</span>

Find the lateral area and surface area of a cone with a radius of 12 and a height of 21
marishachu [46]

Answer:

The Lateral Surface Area is 911.32 square unit and

Total Surface Area is 1361.7 square unit.

Step-by-step explanation:

For a given Cone

Radius (r) = 12

Height (h) = 21

<u>For Lateral Surface Area</u>

<h3><u>Formula</u><u>:</u> </h3>

A = πr√r² + h²

A = 3.14 × 12 × √(12)² + (21)²

A = 3.14 × 12 × √144 + 441

A = 3.14 × 12 × √585

A = 37.68 × 24.18

A = 911.32 square unit

Now,

<u>For</u><u> </u><u>Total</u><u> Surface Area</u>

<h3><u>Formula:</u></h3>

A = πrl + πr²

For Slant height (l)

l² = r² + h²

l² = (12)² + (21)²

l² = 144 + 441

l² = 585

l = 24.18

So,

A = πrl + πr²

A = πr(l + r)

A = 3.14 × 12 × (24.14 + 12)

A = 3.14 × 12 × 36.14

A = 1361.7 square unit

Thus, The <u>Lateral Surface Area</u> is 911.32 square unit and <u>T</u><u>otal Surface Area</u> is 1361.7 square unit.
