Answer:

88.2

80(1+0.05)* 2

Step-by-step explanation:

The number of birds in the park in 1997 is given by the equation A = 88.2 birds

What is exponential growth factor?

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the number of birds in 1997 be represented as A

Now , the equation will be

The number of birds in 1995 x₀ = 80 birds

The time n = 1997 - 1995 = 2 years

The percentage of increase r = 5 %

The number of birds A is calculated by exponential growth factor ,

Substituting the values in the equation , we get

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( 2 ) = 80 ( 1 + ( 5/100 ) )²

On simplifying the equation , we get

x ( 2 ) = 80 ( 1 + 0.05 )²

x ( 2 ) = 80 ( 1.05 )²

x ( 2 ) = 80 x 1.1025

x ( 2 ) = 88.2 birds

Therefore , the value of A is 88 birds

Hence , the number of birds is 88 birds

Answer:

£9095

Step-by-step explanation:

Given data

P=£8500

T= 3 years

R= 2.3%

The compound interest formula is

A= P(1+r)^t

substitute

A=8500(1+0.023)^3

A=8500(1.023)^3

A=8500*1.07

A=£9095

Hence the savings after 3 years is £9095

Step-by-step explanation:

65*2=130

Answer:

You would use the distributive property.

Step-by-step explanation:

2(x+4) = 2x+8

2x+8x = 2x+8

10x = 2x+8

10x - 2x = 2x-2x+8

8x = 8

8x/8 = 8/8

x = 1

Answer:

120.

Step-by-step explanation:

Using the Pythagoras theorem:

(30√2)^2 = x^2 + x^2         where x =length of each side of the square

1800 = 2x^2

x^2 = 900

x = 30.

So the perimeter = 4*30 = 120.

Answer:

slope={-3-6}/(-1-4)=-9/-5=9/5

Answer:

slope is 3/5 very simple

Answer:

Slope=1

Step-by-step explanation:

The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Combine 13 1 3 and x x . Rewrite in slope-intercept form. Using the slope-intercept form, the slope is 13

Answer:

i think its 12%

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

Step-by-step explanation:

1. Pick two points on the line and use them to find the slope.

2. Then, find the coordinates of the y-intercept.

3. The y- coordinate is the value of b in the equation.

Answer:

Step-by-step explanation:

First find the slope of the line.

If the 2 points are (x1, y1) and (x2, y2) then the slope is (y2-y1)/(x2-x1).

Then we can use the point-slope form of the equation of the line:

y - y1 = m(x - x1)  where m = the slope and by substituting the point (x1, y1) we can  convert the equation to slope intercept form ( which is y = mx + b).

Example:

Find slope-intercept equation for the line joining  the points (1, 0) and (3, 4):

The slope = (4 - 0)/(3 - 1) = 4/2 = 2.

Now we plug in the slope m and the point (3, 4) into  y - y1 = m(x - x1):

y - 4 = 2(x - 3)       (Note we can use (1, 0) OR (3, 4) as they are both on line).

y - 4 = 2x - 6

y = 2x - 6 + 4

y = 2x - 2 which is slope-intercept form.

Answer:

y = 4x-13

Step-by-step explanation:

The standard equation of the line is y = mx+c

m is the slope

c is the intercept

Given the equation y = 4x+2

The slope m = 4

Substitute m = 4  and the given point into the formula y = mx+c

1 = 4(4)+c

1 = 14+c

c = -13

Get the equation

Recall that y = mx+c

y = 4x + (-13)

y = 4x-13

Hence the required equation is y = 4x-13

  - Now that we did that, you have to make it into a rule that makes sense, if we did [tex](y)[/tex] ÷ [tex](x)[/tex], the table would change. So to make it work you do the opposite of what we did to find the 10 value. This makes it multiplying [tex](x)[/tex] by 10.

So your answer is [tex]\bold{y=10x}[/tex].

Answer:

m<C = 34.4 °

Step-by-step explanation:

From the question given above, the following data were obtained:

Opposite = AB = 35

Hypothenus = AC = 62

Angle C =?

The value of m<C can be obtained by using sine ratio as illustrated below:

Sine C = Opposite /Hypothenus

Sine C = 35 / 62

Sine C = 0.5645

Take the inverse of sine

C = Sine¯¹ 0.5645

C = 34.4 °

Thus,

m<C = 34.4 °
