Answer:

24 cm^2

Step-by-step explanation:

Find Side Length:  

20cm/4 = 5cm

Use x:  

First Diagonal - 4x; Second Diagonal = 3x  

Pythagorean Theorem:  

a^2 + b^2 = c^2  

Use Pythagorean Theorem:

a = 1/2 of First Diagonal  

b = 1/2 of Second Diagonal  

c = Side Length  

2x^2 + 1.5x^2 = 5^2

4x^2 + 2.25x^2 = 25  

6.25x^2 = 25

x^2 = 4

x = 2  

Formula for Area of Rhombus:

1/2 * First Diagonal * Second Diagonal

Use Formula for Area of Rhombus:

1/2 * 4(2) * 3(2)

2. The parameter "b": Compare the graphs of several different exponential growth functions in
Mathematica to discover the significance of the parameter "b". Explain in detail what the
parameter "b" tells you about the graph of an exponential growth function.

Answers

Answer:

See explanation

Step-by-step explanation:

Required

The significance of "b" in exponential function

An exponential function is represented as:

[tex]y = ab^x[/tex]

In the above equation, parameter "b" is the rate of the function

In other words, the constant multiplier of the function.

Take for instance;

[tex]y = 2*4^x[/tex]

By comparison:

[tex]b = 4[/tex]

Another instance is:

[tex]y = 2(-4)^x[/tex]

By comparison

[tex]b = -4[/tex]

Other significance of parameter b are:

If [tex]b > 0[/tex] then b represents a growth factor

If [tex]b < 0[/tex] the b represents the factor of decay

[tex]b \ne 0[/tex] i.e. b is never 0

Write an equation of the line that passes through the point (6, -9) with the given slope m = 3.

Answers

Answer:

y = 3x - 27

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 )

Here m = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (6, - 9) into the partial equation

- 9 = 18 + c ⇒ c = - 9 - 18 = - 27

y = 3x - 27 ← equation of line

8. A juice container shaped like a cylinder has a base area of 100 cm2 and can hold 1500 cm3 of juice. The height of the juice container is

Answers

Answer:
15 cm

Explanation:
The cylinder’s volume can be found by multiplying base by height. The formula for this would be base*height=volume. The base and volume are given, so plug the values in and solve for height.

base*height=volume
100*height=1500
height=15 cm

The height of a juice cylinder container with base area of 100 cm² and volume of 1500 cm³ is 15 cm

Base area of a cylinder

Base area = πr²

base area = 100 cm²

100 = π × r²

r² = 100 / π

r = √100 / π

Volume of a cylinder  

volume = πr²h

1500 = π (√100 / π)² × h

1500 = π(100 / π) × h

1500 = 100h

divide both sides by 100

h = 1500 / 100

h = 15 cm

The wind is blowing opposite to leg AB. Given the fact that you’re traveling in a wind-powered boat, which leg of the course will take you the longest? Why? (4 points)

Answers

Answer:

The leg of the course that will take longest is from A to B

The reason is that the leg of the course, A to B is slowed by the wind

Step-by-step explanation:

The direction of the wind is opposite to leg AB

The starting and finishing point is point A, and the course is from A to B to C and back to point A

The leg of the course that will take the longest is course in which th motion is against the wind which is from B to A

The motion from B to C and from C to A are partly in the wind ward direction, because the wind would be behind the sales and will therefore be aided by the wind, leading to rapid motion

However, the starting motion on the leg from A to B is opposite the wind and will be slowed down by the wind, and would therefore, take the longest.

Answer:

z =86

Step-by-step explanation:

The exterior angle of a triangle is the sum of the opposite interior angles

z + z-39 = z+47

2z-39 = z+47

Subtract z from each side

z-39 = 47

Add 39 from each side

z = 47+39

z =86

The given information is,

To find the required value of z.

Property we use,

The exterior angle of a triangle is the sum of the opposite interior angles.

Now we can get the value of z,

→ z + z-39 = z + 47

→ 2z-39 = z + 47

→ 2z -z = 47 + 39

→ z = 47 + 39

→ [z = 86]

Thus, the required value of z is 86.

Which linear inequality is represented by the graph?
O x < 2 x + 3
Oy> x+3
O y>x+3
O y<{x+3
-3 -2 -1

Answers

It’s y>x+3 the third one

The linear inequality that represents the graph is y > (2/3)x + 3.

Option C is the correct answer.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

y < (2/3)x + 3

y > (3/2)x + 3

y > (2/3)x + 3

y < (3/2)x + 3

The graph is on the positive side of the y-coordinate so,

We can consider:

y > (3/2)x + 3

y > (2/3)x + 3

Now,

Plotting in a graph we see that,

We need to have the y-intercept at y = 3 and the x-intercept at x = 4.5.

So,

y > (2/3)x + 3 satisfied.

Thus,

y > (2/3)x + 3 represents the graph.

Patricia has $34,000 to invest. She invests some at 17% and the balance at 20%. Her total annual interest income is $6245. Find the amount invested at each rate

Answers

Answer:

she invest $18,500 at the 17% rate and $15,500 at the 20% rate.

Step-by-step explanation:

Suppose that you invest some quantity A to an invest rate of x%

At the end, the amount you will have is given by:

Amount = A + A*(x%/100%)

Where:

A*(x%/100%)  is the interest income

So, here she initially has $34,000

And she invest some quantity X to a 17% and a quantity Y to 20%

Then we have:

X + Y = $34,000

And we know that her total anual income is $6245

X*(17%/100%) + Y*(20%/100%) =  $6245

Then we have a system of two equations:

X + Y = $34,000

X*(17%/100%) + Y*(20%/100%) =  $6245

First we can rewrite the second one to a more simpler form:

X*(0.17) + Y*(0.20) =  $6245

Now we can isolate one of the variables in the first equation to get:

X = $34,000 - Y

Now we can replace that in the other equation to get:

( $34,000 - Y)*0.17 + Y*0.20 = $6245

Now we can solve this for Y:

$34,000*0.17 + Y*(0.20 - 0.17) = $6245

$5,780+ Y*0.03 =  $6245

Y*0.03 = $6245 - $5,780 = $465

Y = $465/0.03 = $15,500

And X = $34,000 - Y = $34,000 - $15,500 = $18,500

So she invest $18,500 at the 17% rate and $15,500 at the 20% rate.

OA) 800 seats

Answers

Answer:

A) 800 seats

Step-by-step explanation:

Notice that an arithmetic sequence is formed with the number of seats. Since we're adding one seat each row, the last (25th) row will have 44 seats since the first row has 20 seats.

The sum of an arithmetic sequence is given by:

[tex]S_n=n\left(\frac{a_1+a_n}{2}\right)[/tex], where [tex]n[/tex] is the number of terms, [tex]a_1[/tex] is the first term, and [tex]a_n[/tex] is the last term

Therefore, substituting [tex]a_1=20[/tex], [tex]a_n=44[/tex], and [tex]n=25[/tex], we get:
