Write the equations for 74,25a n d 49

Answers

Answer:

The two equations are

1) 25 + 49 = 74

2) 74 - 25 = 49

Step-by-step explanation:

Given numbers 74 , 25 and 49

We have to write the equations using the numbers 74, 25 and 49

Since, we can apply two operations addition and subtraction that involves all the three numbers together.

So first equation becomes,

When we add 25 and 49 we get 74

Written mathematically as 25 + 49 = 74

and second equation becomes,

When we subtract 25 from 74 we get 49

Written mathematically as 74 - 25 = 49

Thus, the two equations are

1) 25 + 49 = 74

2) 74 - 25 = 49

7425 ? 49

At the grocery store, you can buy gum in a 6 pack for $11.70 or a 12 pack of gum for $23. Which is the better deal and what is the price per pack of gun if the better deal?

Answers

The better deal is the 12 pack. You would have more gum per dollar. If you bought two six packs, you would be paying $1.95 for a piece of gum. If you bought the 12 pack you would be paying 1.916 (repeating) for a pice of gum.

What is the derivative of e^(2x)

Answers

Answer:

$\displaystyle (d)/(dx)[e^\big{2x}] = 2e^\big{2x}$

General Formulas and Concepts:

Calculus

Differentiation

Derivatives
Derivative Notation

Derivative Property [Multiplied Constant]: $\displaystyle (d)/(dx) [cf(x)] = c \cdot f'(x)$

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Derivative Rule [Chain Rule]: $\displaystyle (d)/(dx)[f(g(x))] =f'(g(x)) \cdot g'(x)$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle y = e^\big{2x}$

Step 2: Differentiate

Exponential Differentiation [Derivative Rule - Chain Rule]: $\displaystyle (d)/(dx) = e^\big{2x} \cdot (d)/(dx)[2x]$
Basic Power Rule [Derivative Property - Multiplied Constant]: $\displaystyle (d)/(dx) = e^\big{2x} \cdot 2$
Simplify: $\displaystyle (d)/(dx) = 2e^\big{2x}$

What is the volume of this sphere?Use 3.14 for pi and round to the nearest hundredth when necessary.

113.04 cm³

678.24 cm³

904.32 cm³

7234.56 cm³

Answers

Answer:

The volume of the sphere is $904.32\ cm^(3)$

Step-by-step explanation:

we know that

The volume of the sphere is equal to

$V=(4)/(3)\pi r^(3)$

In this problem we have

$D=12\ cm$ -----> given problem

Find the radius

$r=12/2=6\ cm$ ----> the radius is half the diameter

substitute

$V=(4)/(3)(3.14)(6^(3))=904.32\ cm^(3)$
