Graphing Exponential Function in Exercise ,sketch the graph of the function.See example 3 and 4.

9966 [12]

Answer:

The graph is attached below.

Step-by-step explanation:

Considering the exponential function

$y=3^{-2x}$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^{bx}=\left(a^b\right)^x$

$3^{-2x}=\left(3^2\right)^{-x}$

$=\left(3^2\right)^{-x}$

$=9^{-x}$

The graph is also attached below.

Henry takes 1 hour to drive to work and 1 hour to drive home. if he works 5 days a week, how many hours does he spend driving to

alisha [4.7K]

Answer:

Step-by-step explanation:

Time taken to drive to work = 1 hr

Time taken to drive home = 1 hr

Time taken to drive from home to work and back home again ( IN ONE DAY)

=1 + 1 = 2hrs

So time taken for driving to and from work for 5 days = 2hrs × 5 days = 10 hrs .

1.Write this sentence as an equation.Do not solve it.

Ivahew [28]

Problem 1

x = some unknown number

3x = three times a number

3x-7 = difference of three times a number and seven

2(3x-7) = two times the difference of three times a number and seven

2(3x-7) = x

The last equation is formed because the expression we built up is equal to the original number in question

<h3>Answer: 2(3x-7) = x</h3>

===========================================================

Problem 2

Use the distribution rule to get

3(2x+4)-2x

3*2x+3*4-2x

6x+12-2x

From here, we combine like terms. That means we combine the 6x and -2x to get 4x

So 6x+12-2x simplifies to 4x+12 and not 16x

How did she get 16x? Possibly because she mistakenly thought she could add 4x to 12 to get 16x. This only works if the 12 had x attached to it.

In other words, this is valid: 4x+12x = 16x but this is not 4x+12 = 16x

===========================================================

Problem 3

L = length = horizontal dimension = (d+15) ft

W = width = vertical dimension = (d-3) ft

P = perimeter of the rectangle = 108 ft

P = 2(L+W)

108 = 2(d+15+d-3)

108 = 2(2d+12)

108 = 4d+24

4d+24 = 108

4d = 108-24

4d = 84

d = 84/4

d = 21

The deep end is 21 feet long.

This means the overall horizontal length is d+15 = 21+15 = 36 feet and the the vertical width is d-3 = 21-3 = 18 feet

The overall dimensions of the rectangular pool are 36 ft by 18 ft

<h3>Answer: d = 21</h3>

so, I need to just find the missing length, if you can, please explain the pythagorean theorem to find the missing side. I don't

ANTONII [103]

The surface area of the triangular prism is 828 in².

Solution:

Let the missing length of the triangle be x.

Using Pythagoras theorem,

In right triangle, square of the hypotenuse is equal to the sum of the squares of other two sides.

$12^2+x^2=15^2$

$144+x^2=225$

Subtract 144 on both sides of the equation.

$x^2=225-144$

$x^2=81$

Taking square root on both sides, we get

x = 9

The missing length of the triangle is 9 in.

Area of the front triangle = $\frac{1}{2}\times 12\times 9$

= 54 in²

Area of the back triangle = $\frac{1}{2}\times 12\times 9$

= 54 in²

Area of the sloping rectangle = 20 × 9

= 180 in²

Area of the back rectangle = 20 × 12

= 240 in²

Area of the base rectangle = 20 × 15

= 300 in²

Total area = 54 in² + 54 in² + 180 in² + 240 in² + 300 in²

= 828 in²

The surface area of the triangular prism is 828 in².
