The population of a city is 40,000 and the annual growth rate is 1.6%. Write an equation to model the population y after x years.

Answers

Y=40,000(1.016)^x

Explanation:

years= x

Predicted population= y

Initial population= 40000

you can find the population y after x years with the help of this function

For example:

If we want to know the population after 5 years, put x=5 and find y

Y after 5 years= 40000(1.016)^5

A bookcase is 8 feet high, 1 foot deep, and 2 feet wide. How much space (in volume) does the bookcase take up?

Answers

Answer:

The volume of the bookcase is 16 cubic feet.

Step-by-step explanation:

Hey there!

We are given three values (in feet) and asked to find the volume of a bookcase:

8 feet high1 foot deep2 feet wide

We want to find the volume. In order to do this, we need to define:

the formula for finding the volume of a rectangular prismwhat values our data fits with

Therefore, the formula for volume is: [tex]v = l \times w \times h[/tex]

[tex]v[/tex] - volume[tex]l[/tex] - length[tex]w[/tex] - width[tex]h[/tex] - height

Finally, we need to assign each number value to either the length, the width, or the height.

Wide is a synonym for width, so our width is 2 feet.

Deep is another way of saying the space inside of the bookshelf, which would be the length (1 foot).

High would refer to how tall something is, so the height is 8 feet.

Now, let's plug in our values and solve for [tex]v[/tex].

[tex]v = l \times w \times h[/tex][tex]v = 1 \times 2 \times 8[/tex][tex]v = (1 \times 2) \times 8[/tex][tex]v = 2 \times 8[/tex][tex]v = \text{16 cubic feet}[/tex]

It's important to note that since we are finding volume, our measurement of feet becomes cubic feet.

Therefore, the volume of the bookcase is 16 cubic feet.

Find the measure of the angle indicated. Assume that lines which appear tangent are tangent.

Find an equation of the line that bisects the acute angle formed by the graphs of negative 5X plus 7Y +4 equals zero and 7X minus 5Y +6 equals zero

Answers

Answer:

Step-by-step explanation:

x+ y = 0

and

-2x + 5y + 2 = 0

Step-by-step explanation:

given line

3x+5y+2=0

5x+3y-2=0

solution

when two line bisect each other then line equation of bisector is express as

and here

A1 = 3

B1 = 5

C1 = 2

and

A2 = 5

B2 = 3

C2 = -2

so now put value in equation 1 we get

solve it we get

-2x + 5y + 2 = 0 1

and

3x+5y+2 = - ( 5x+3y-2 )

solve it we get

SOLUTION:

THANK, ;)

Answers

No they are not because 9/6 cannot be reduced to 6/4

Answer: 9/6 and 6/4 are equivalent

Step-by-step explanation:

If you simply 9/6, you get 1 3/6

Simplify 6/4, you get 1 2/4

3/6 and 2/4 both equal 1/2, so 9/6 and 6/4 both equal 1 1/2. Therefore, they are equivalent.

how do you solve

just seeing how to sole this equation

Answers

Answer:

this is a simultanious equation and u need one more equation to do it

Step-by-step explanation:

there are many answers if u dont have the second equation.

You can just substitute a number in x then find y

eg.

x= 12/7 , y =0.5

Answer:

1. 7 x - 4 y = 10. 7x−4y=10. Add 4y to both sides. Add 4y to both sides.

2. 7x=10+4y. 7x=10+4y. The equation is in standard form. The equation is in standard form.

3. 7x=4y+10. 7x=4y+10. Divide both sides by 7. Divide both sides by 7.

4. \frac{7x}{7}=\frac{4y+10}{7} 77x=74y+10 Dividing by 7 undoes the multiplication by 7.

If the volume of a solid cone is 440cm3 and
its perpendicular height is 14cm. Determine
its base diameter to the nearest whole
number
O a. 5.5cm
b. 12cm
С. 6cm
d. 11cm

Answers

Answer:

Step-by-step explanation:

1/3 nr^2h = volume of a cone

1/3 x 22/7 x 14 x r^2 = 440

r^2 = 440 x 3 x 7/22 x 1/14

r^2 = 30

r = 30

r = 5

The base diameter to the nearest whole number is 11cm

The volume of a cone

The formula for calculating the volume of a cone is expressed as:

V =1/3πr²h

Given the folllowing parameters

V = 440cm^3

h = 14cm

Substitute the given parameters

440 = 1/3(22/7) * 14r²

440 = 44/3 * r²

10 = r²/3

r² = 30

r = 5.5cm

d = 11cm

Hence the base diameter to the nearest whole number is 11cm
