Answer:

Domain and Range in set notation

Domain: {x|x=4,0,-2}

Range: {x|x=-1,4,9,-9}

Step-by-step explanation:

We are given a relation G

G={(4,-1),(0,4),(-2,9),(-2,-9)}

We need to find domain and range of the relation G

Domain: The domain is the set of all first elements of ordered pairs (x-coordinates)

Range: The range is the set of all second elements of ordered pairs (y-coordinates).

So for the given relation G={(4,-1),(0,4),(-2,9),(-2,-9)}

Domain is: (4,0,-2)

Range is: (-1,4,9,-9)

So, Now writing Domain and Range in set notation

Domain: {x|x=4,0,-2}

Range: {x|x=-1,4,9,-9}

Answer: 11 years

Step-by-step explanation:

You can use the Rule of 72 which is a way to calculate quickly, the time it will take for an investment to double given its interest rate.

It works by:

= 72 / Interest rate

Rate is compounded quarterly so the periodic rate is:

= 6.56%/4

= 1.64%

Time taken to double = 72/1.64

= 43.9 quarters

In years that is:

= 43.9/4

= 11 years

For an investment to double in value at an interest rate of 6.56% compounded quarterly, the period required is exactly 10.625 years.

The future value of an investment refers to the compounded value of its present cash flows in the future, using a stated interest rate.

The future value can be determined using the future value table or formula.

We can also determine the future value using an online finance calculator, which also enables us to determine the period required to double the present value of the investment at 6.56%.

I/Y (Interest per year) = 6.56%

PMT (Periodic Payment) = 0

FV (Future Value) = $15,000

P/Y (# of periods per year) = 4

C/Y (# of times interest compound per year) = 4

Results:

PV = $7,513.52

Total Interest $7,486.48

N (# of periods) = 42.5 (10.625 years x 4)

The period = 10.625 years (42.5/4)

Thus, for an investment to double in value at an interest rate of 6.56% compounded quarterly, the period required is exactly 10.625 years.

Answer: 6/5

Step-by-step explanation:

When finding the reciprocal, we essentially just "flip" or take the inverse of the number we are given. For example, the reciprocal of 1/2 would be 2/1 or 2. The given number multiplied by the reciprocal should always equal 1. If it does, then we know we are correct.

In this case, we are finding the reciprocal of 5/6, so we "flip" the numerator and the denominator to get 6/5.

To check our work, we need to multiply our original number and its reciprocal.

5/6 x 6/5 = 30/30 = 1

Now, we know we are correct, that the reciprocal of 5/6 is 6/5.

Answer:

The average rate of change for the function over the given integral

[tex]A(x) = \frac{e^{-2} -1}{2}[/tex]

Step-by-step explanation:

Explanation

Average rate of a function:-

We can define the average rate of change of a function from a to b

[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]

Given function f(x) = eˣ

Given interval      x = a = -2   and y = b = 0

f(a) = f(-2) = e⁻²

f(b) = f(0) = e⁰

[tex]A(x) = \frac{e^{-2} -1}{0-(-2)}[/tex]

Answer:

In the ocean, warmer water expands just like any other matter, and following the principle of density, it rises to the top of the ocean. The cooler water, which is more dense than the warm water, sinks to the bottom and takes up the space left by the rising warm water. The result is a convection current.

Step-by-step explanation:

Answer:

188 weeks of data must be sampled.

Step-by-step explanation:

From the information given, we can deduce that:

The Margin of error is within = 200

The confidence interval = 95%

The level of significance = 1 - C.I

= 1 - 0.95

= 0.05

The standard deviation = 1400

The number of weeks the data must be sampled can be determined by using the formula for sample size which is:

[tex]n =( \dfrac{Z_{\alpha/2} \times \sigma}{E} )^2[/tex]

[tex]n =( \dfrac{Z_{0.05/2} \times 1400}{200} )^2[/tex]

[tex]n =( \dfrac{1.96 \times 1400}{200} )^2[/tex]

[tex]n =( \dfrac{2744}{200} )^2[/tex]

[tex]n =( 13.72)^2[/tex]

n = 188.24

n ≅ 188

Thus, 188 weeks of data must be sampled.

Answer:

9. SSS

10. ASA

11. NONE

12. NONE

Step-by-step explanation:

9. The figure shows two triangles with two corresponding sides indicated to be congruent to each other. The third side is shared by both triangles. Therefore, by the SSS Congruence Theorem, both triangles are congruent to each other. Three sides of one triangle is congruent to the corresponding sides of the other.

10. The figure shows that two angles of one ∆ is congruent to two corresponding angles of the other ∆. Also, the triangles share a common side. This side is an included side between the two given angles. Therefore, by ASA Congruence Theorem, both triangles are congruent to each other.

11. This figure shows the two triangles have 3 corresponding equal angles. This is not enough to prove they are congruent.

12. The two triangles has two corresponding congruent sides given. However, we don't have enough information to determine if they are congruent to each other.

1936 m2

Lot = 60 x 36 = 2160m^2

House = 28 x 8 = 224m^2

Area not covered by the house = 2160^2 - 224^2

= 1936m^2

Step-by-step explanation:

Notice that the set {49, 17, 4, 18} has a mean of (49+17+4+18)/ 4 = 22, and it is spread from the smallest value (4) in 18 units. This is the largest spread from the mean compared to the other 3 sets whose maximum spreads are: 16, 8,and 8.

Answer:

100 days

Step-by-step explanation:

If you have 60 customers that pay everday $50, 60 multiplied by $50 is $3,000 a day. You take your debt, 300,000 and divide that with the 3,000. Thus gives the answer 100 days.

Answer:

100 days

Step-by-step explanation:

First, you must take the 60 customers and multiply it by the $50 daily. That equals 3,000 dollars, so the restaurant is earning that much each day. In order to make 300,000 dollars, it would take 100 days. This is because 300,000/3,000 is 100. I hope this helps!:))

Answer:

C

Step-by-step explanation:

Answer:

C choice.

Step-by-step explanation:

We can either solve the equation or substitute x = 4 to find the true equation.

Solve The Equations

1. 4x=20

Our solution would be x = 5 as we move 4 to divide 20.

2. x/2=8

Our solution would be x = 16 as we move 2 to multiply 8.

3. x+8=3x

Our solution would be x = 4 which is the answer. We basically move x to subtract 3x as we get 8 = 2x.

Then we move 2 to divide 8 as we get x = 4.

[tex]x + 8 = 3x \\ 8 = 3x - x \\ 8 = 2x \\ \frac{8}{2} = x \\ x = 4[/tex]

4.

[tex]x = \frac{x + 5}{2} \\ 2x = x + 5 \\ 2x - x = 5 \\ x = 5[/tex]

We simply multiply the whole equation by 2 to get rid of the denominator.

Answer:

A = 192 cm²

Step-by-step explanation:

Given that,

The length of the diagonal of a rectangle is 20 cm.

The difference between its length and its width is 4 cm.

Let the length is l and width is b.

ATQ,

l-b = 4 ...(1)

Let x is the diagonal of the rectangle such that,

[tex]x^2=l^2+b^2[/tex]

or

[tex]20^2=l^2+b^2\\\\l^2+b^2=400[/tex] ....(2)

Now we need to solve equation (1) and (2).

Squaring equation (1) : [tex]l^2+b^2-2lb=16[/tex]

Put equation (2) in above equation.

[tex]400-2lb=16\\\\400-16=2lb\\\\2lb=384\\\\lb=192[/tex]

Since, the area of the rectangle, A = lb

A = 192 cm²
