Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

y - 3 = [tex]\frac{1}{4}[/tex] (x - 2 ) ← distribute parenthesis

y - 3 = [tex]\frac{1}{4}[/tex] x - [tex]\frac{1}{2}[/tex] ( add 3 to both sides )

A linear regression equation that represents the data set is y = 39.7x + 1127.8. Also, the number of new cases for 2011 is equal to 1525 cases.

In this scenario, the Year since 2002 (x) would be plotted on the x-axis of the scatter plot while the New cases (y) would be plotted on the x-axis of the scatter plot.

From the Excel sheet, you should right click on a data point on the graph (scatter plot), select format trend line and then tick the box to display an equation for the linear regression (line of best fit) on the graph.

By critically observing the scatter plot (see attachment) which models and shows the relationship given in the table, an equation for the linear regression is given by:

y = 39.7x + 1127.8

For 2011, the value of x is given by:

x = 2011 - 2002 = 9 + 1 = 10 years.

Now, we can determine the new cases for 2011:

y = 39.7(10) + 1127.8

y = 397 + 1127.8

y = 1524.8 ≈ 1525 cases.

Answer:

x = 126

Step-by-step explanation:

The angle indicated with 126° and the angle represented with (5y - 4) are alternate angles and their measures are equal so we can write the following equation to find the value of y:

5y - 4 = 126 add 4 to both sides

5y = 130 divide both sides by 5

y = 26

x and the angle indicated with 126 are also alternate angles so

x = 126

The angle represented with (5y - 4) are the angle represented with (6z + 6) are supplementary angles and their sum is equal to 180, we can write the following equation based on this information:

6z + 6 + 126 = 180 add like terms

6z + 132 = 180 subtract 132 from both sides

6z = 48 divide bot sides by 6

z = 8

a. The function m = 200 - 50v is interpreted as

m = amount left

200 = amount available for buying video games

50 = cost per video game

v = number of video games

b. The domain of the function is 0 < v ≤ 4

the domain is discrete

c. explanation of the graph is below

In the graph, the input values is the number of video games, v while the output value is amount, m(in dollars) left for buying games.

The domain is controlled by the input values. considering the amount set out for games which is 200 we solve for v at zero amount

0 = 200 - 50v

50v = 500

v = 4

The maximum number of video games the amount can buy is 4. For the minimum we can not buy 0 video game but the graph can show amount available before buying the game.

The domain starts from 0, with 0 not inclusive to 4 with 4 included

The profit is P 12 after selling the bananas for P 2.50 each after applying the simple arithmetic.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

For the first part:

1 Peso=4 pieces of 25 centavo coins  

1 Peso=10 pieces of 10 centavo coins

Total length = 2.5 meters

1 floweret uses 5 decimeters

1 decimeter = 1/10 meters

2.5 meter in decimeter

250 decimeter

Total floweret = 250/5 = 50

Total money = 10x50 = P 500

The total cost of bananas = 18

The bananas sold = 2.50(12) = 30

You will have $1,09,545.455 in the account in 20 years. An you will put total $72,000 in the account. And you will earn $37,545.455 of total interest.

Here,

We deposit $300 each month earning 4% interest compounded monthly.

we will find the future value of this amount after 20 years.

for finding future value, The general formula is

FV=PV∙(((1+i)ⁿ-1))/i

Where,

FV= future value

PV=present value

i=interest

n=time period

now, our PV=300$ and we have 4% interest compounded monthly

i.e.

i=4/100∙1/12

i=0.0033

And, the period of time is

n=20×12

n=240

Now, we will calculate the future value

FV=300 (((1+0.0033)²⁴⁰-1))/0.0033

FV=300 (((1.0033)²⁴⁰-1))/0.0033

FV=300 (((2.205)-1))/0.0033

FV=300(365.15)

FV=1,09,545.455$

Now, The total money you put into account is

total amount=300×20×12

total amount=72,000$

The equivalent function of the exponential function is (e) f(x) = 11ˣ

From the question, we have the following function that can be used in our computation:

f(x) = (1/11)^-x

This function can be properly expressed as

f(x) = (1/11)⁻ˣ

Solving further, we need to apply the exponent law of indices

This is represented as

a⁻ˣ = 1/aˣ

When the above rule is applied, we have

f(x) = 1/(1/11)ˣ

Evaluate the quotient

f(x) = (11/1)ˣ

This gives

f(x) = 11ˣ

Hence, the equivalent is (e) f(x) = 11ˣ

The angle a formed at the exterior of the hexagon by a line that goes through a vertex to the center of the hexagon and a second line that touches the adjacent vertex is a = 30°

The properties of a regular hexagon includes;

There are 6 equilateral triangles in a regular hexagon

The triangle ΔOAC formed by the segment that extends into the hexagon is an equilateral triangle.

Therefore;

Triangle ΔABC is an isosceles triangle with segment AC ≅ Segment AB

Therefore;

Angle ∠C is congruent to angle ∠B (base angles of an isosceles triangle

∠C ≅ ∠B

m∠C = m∠B (definition of congruency)

m∠B = a

Therefore;

m∠C = m∠B = a

m∠C = a (substitution property)

From external angle to a triangle, postulate, we get;

m∠OAC = m∠B + m∠C

Therefore;

m∠OAC = a + a

$6500 is invested at the rate of 6% and $500 is invested at the rate of 8%.

What is annual interest rate?

An annual percentage rate is expressed as an interest rate. It calculates what percentage of the principal you'll pay each year by taking things such as monthly payments into account.

Invested amount = $7000

Let x be the invested amount at 6% and y be the invested amount at 8%.

According to the question,:

x+y=7000......(1)

annual interest is $430.

Therefore Interest on x + interest on y = $430

Interest=(invested amount*rate*time)/100

Here Time is 1 year.

(6*x)/100+(8*y)/100=430

This shows, 6x+8y=43000.......(2)

From equation (1), we have:

x=7000-y.........(3)

Substitute the value of x in equation (2),

6(7000-y)+8y=43000

On simplifying, y=500

Put y = 500 in equation (3)

we get x=6500

Therefore $6500 is invested at the rate of 6% and $500 is invested at the rate of 8%.

The values of t for which the ball's height is 20 feet are t = 1.64 seconds and t = 0.61 seconds

From the question, we are to determine all values of t for which the ball's height is 20 feet

From the given information,

The ball's height h (in feet) after seconds is given by the following:

h = 4 + 36t - 16t²

To determine all values of t for which the ball's height is 20 feet, we will substitute h = 20 in the equation

h = 4 + 36t - 16t²

Substitute h = 20

20 = 4 + 36t - 16t²

Rearrange

16t² - 36t + 20 - 4 = 0

16t² - 36t + 16 = 0

Divide through by 4

4t² - 9t + 4 = 0

Solve the equation quadratically

Using the quadratic formula,

t = [-b ± √(b² - 4ac)]/2a

a = 4, b = -9, and c = 4

t = [-(-9) ± √((-9)² - 4(4)(4))]/2(4)

t = [9 ± √(81 - 64)]/8

t = [9 ± √(17)]/8

t = [9 ± 4.12]/8

t = [9 + 4.12]/8 and t = [9 - 4.12]/8

t = 13.12/8 and t = 4.88/8
