Answer:

amplitude = 3

Step-by-step explanation:

The standard form of a cosine function is

f(x) = a cos(bx + c) + d

amplitude = | a |, period = [tex]\frac{2\pi }{b}[/tex]

phase shift = - [tex]\frac{c}{b}[/tex], d is the vertical shift

Given the above function, then

Step-by-step explanation:

First find x and y.

Solve system of equations by elimination.

  3x-y=3

+(-x+y=3)

---------------

2x=6

x=3

Now plug in x into one of the equations to find y.

-3+y=3

y=6

xy=3x6=18

Final answer:

The product of xy, given the system of equations 3x - y = 3 and -x + y = 3, is 18. This is found by first solving for x and y using the elimination method and then multiplying the obtained values.

Explanation:

To find the product of xy, we need to solve the system of equations given by 3x - y = 3 and -x + y = 3. Here we'll use the elimination method. Adding both equations together, we eliminate y:

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

Which simplifies to:

2x = 6

Dividing both sides by 2, we get:

x = 3

To find y, we substitute x back into one of the original equations, for example, the second equation -x + y = 3:

-(3) + y = 3

-3 + y = 3

Adding 3 to both sides gives us:

y = 6

Now we can find the product of xy:

xy = 3 * 6

xy = 18

Therefore, the product of xy is 18.

Answer: 3.75 gallons

Step-by-step explanation:

8 fl oz x 60 (minutes)=480 fl oz

480 fl oz ÷ 128=3.75 gallons

Water flow rate is defined as the volume of the fluid passing by some location. The water leaking from the pipe per hour is 3.75 gallons

A pipe is leaking at the rate of 8 fluid ounces per minute.

Water flow rate is defined as the volume of the fluid passing by some location.

As the flow rate is 8 fluid ounces per minute. In a hour there is total 60 minutes. Thus the flow rate of the pipe in fluid ounces per hour is,

[tex]Q=8\times60[/tex]

[tex]Q=480[/tex]

A fluid ounces is the unit of the measurement of the liquid. There is total 128 fluid ounces in a gallons. Thus the flow rate of the water in gallon can be calculated by dividing the 480 by 128. Thus the flow rate of pipe in gallons per hour is,

[tex]Q=\dfrac{480}{128}[/tex]

[tex]Q=3.75[/tex]

Hence the water leaking from the pipe per hour is 3.75 gallons.

Length = 17, Width = 6

Step-by-step explanation:

Let the length be L and width be W.

L = 3W - 1 , and,

2(L + W) = 46 => L+W = 23  => L = 23 - W, putting this into L = 3W - 1

23 - W = 3W - 1

24 = 4W

W = 6

therefore, L = 23 - W = 17

Answer:

23

Step-by-step explanation:

Note there is a constant difference between consecutive terms

- 1 - (- 4) = - 1 + 4 = 3

2 - (- 1) = 2 + 1 = 3

5 - 2 = 3

This indicates that the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 4 and d = 3, thus

[tex]a_{10}[/tex] = - 4 + (9 × 3) = - 4 + 27 = 23

Given the ratio of seats in the Circle to the Stalls is 2:5 and knowing the number of filled seats in the Circle, we can calculate that there were 1320 filled seats in the Stalls. This brings the total number of filled seats to 1848. However, without information on the theatre's total capacity, we cannot calculate the percentage occupancy.

The ratio of the number of seats in the Circle to the number of seats in the Stalls is 2:5. This means that for every 2 seats in the Circle there are 5 in the Stalls. Given that there were 528 seats filled in the Circle, we can use this ratio to calculate the number of filled seats in the Stalls.

Divide the number of filled Circle seats by 2 (which is 528/2 = 264) and then multiply by 5, which gives us 1320 filled seats in the Stalls. To calculate the total number of filled seats, we add the filled seats in the Circle and the Stalls together (1320 + 528), which gives us 1848 filled seats.

To work out the percentage of occupancy, we must first find out the maximum capacity of the theatre. All we know is the ratio of seats, we don't know the exact total number of seats. Unless we know the total number of seats in the theatre, we cannot work out the percentage of occupancy for last Friday.

The number of occupied seats in the theatre, in both Circle and Stalls is summed up and divided by the total number of seats in the theatre. The result in decimal is multiplied by 100% to get the percentage occupancy. In this case, as all seats were occupied, the percentage is 100%.

The subject of your question involves ratio and percentage, which falls under the category of Mathematics, specifically proportions and ratios. We know that the ratio of the number of seats in the Circle to the number of seats in the Stalls is 2:5. This means that for every 2 seats in the Circle, there are 5 seats in the Stalls. If there were 528 seats occupied in the Circle, since the ratio is 2:5, the number of occupied seats in the Stalls would be (528/2)*5 = 1320. The total number of seats in the theatre is the sum of seats in both Circle and Stalls which is 528+1320 = 1848. The proportion of occupied seats is the sum of occupied seats in both levels (528+1320) divided by the total (1848), which gives us the decimal 1. The percentage of this is 1*100 = 100%. So the percentage occupancy of the theatre last Friday was 100%.

Answer:

The number of marbles does Tommy will get is 18 .

Step-by-step explanation:

Given as :

The total number of  marbles share between Tommy and Robbie = 48

The marbles were distributed between then in the ratio 3 : 5

Let the number of marbles does Tommy have = 3 x

The number of marbles does Robbie have = 5 x

Now,

According to question

The total number of  marbles share between Tommy and Robbie = 48

Or,  the number of marbles does Tommy have + The number of marbles does Robbie have = 48

Or, 3 x + 5 x = 48

Or, 8 x = 48

∴  x = [tex]\frac{48}{8}[/tex]

I.e  x = 6

So, the number of marbles does Tommy have = 3 × 6 =18

The number of marbles does Robbie have = 5 × 6 = 30

Hence the number of marbles does Tommy will get is 18 . Answer

A hospital director is told that 30% of the treated patients are uninsured.

Then, Null Hypothesis : [tex]H_0: p=0.30[/tex]

The director wants to test the claim that the percentage of uninsured patients is less than  the expected percentage.

i.e. Alternative hypothesis : [tex]H_a: p <0.30[/tex]

Answer:

From figure A

The value of ∠ B = 75.74°   ,  ∠ C = 70.26° and  AB = 27.37

From figure B

The value of ∠ A = 42.8°   ,  ∠ B = 106.2° and  AC = 30.04

Step-by-step explanation:

Given first figure as :

AC = 28.2

BC = 16.5

∠ A = 34°

Let AB = c

From law of sines

[tex]\dfrac{a}{Sin A}[/tex] = [tex]\dfrac{b}{Sin B}[/tex] = [tex]\dfrac{c}{Sin C}[/tex]

Or, [tex]\dfrac{a}{Sin A}[/tex] = [tex]\dfrac{b}{Sin B}[/tex]

or, [tex]\dfrac{16.5}{Sin 34}[/tex] = [tex]\dfrac{28.2}{Sin B}[/tex]

Or,  29.506 =  [tex]\dfrac{28.2}{Sin B}[/tex]

Or, Sin B =  [tex]\dfrac{28.2}{29.5}[/tex]  

Or, Sin B = 0.955

∴  ∠B = [tex]Sin^{-1}[/tex] 0.955

I.e∠ B = 75.74

Now, ∠ C = 180° - ( ∠A + ∠B )

Or, ∠ C = 180° - ( 34° + 75.74° )

Or, ∠ C = 70.26°

Now, Again

[tex]\dfrac{b}{Sin B}[/tex] = [tex]\dfrac{c}{Sin C}[/tex]

so,  [tex]\dfrac{28.2}{Sin 75.74}[/tex] = [tex]\dfrac{c}{Sin 70.26}[/tex]

Or,   [tex]\dfrac{28.2}{0.9691}[/tex] = [tex]\dfrac{c}{0.9412}[/tex]

Or, c = 29.09 × 0.9412

∴    c = 27.37

I.e AB = 27.37

Hence,  The value of ∠ B = 75.74°   ,  ∠ C = 70.26° and  AB = 27.37

From figure second

Given as :

AB = c= 12

BC = a = 16

∠ C = 31°

let AC = b

From law of sines

[tex]\dfrac{a}{Sin A}[/tex] = [tex]\dfrac{b}{Sin B}[/tex] = [tex]\dfrac{c}{Sin C}[/tex]

Or, [tex]\dfrac{a}{SinA }[/tex] = [tex]\dfrac{c}{Sin C}[/tex]

or,  [tex]\dfrac{16}{Sin A}[/tex] = [tex]\dfrac{12}{Sin 31}[/tex]

or,  [tex]\dfrac{16}{Sin A}[/tex] = [tex]\dfrac{12}{0.51}[/tex]

Or, [tex]\dfrac{16}{Sin A}[/tex] = 23.52

∴ Sin A = [tex]\dfrac{16}{23.52}[/tex]

I.e Sin A = 0.68

Or,  ∠ A = [tex]Sin^{-1}[/tex] 0.68

or,  ∠ A = 42.8°

Now,  ∠ B = 180° - ( 31° + 42.8° )

Or,  ∠ B = 106.2°

Now,  [tex]\dfrac{b}{Sin B}[/tex] = [tex]\dfrac{c}{Sin C}[/tex]

or,  [tex]\dfrac{b}{Sin 106.2}[/tex] = [tex]\dfrac{16}{Sin 31}[/tex]

Or, [tex]\dfrac{b}{0.96}[/tex] = [tex]\dfrac{16}{0.51}[/tex]

or, b = 31.3×0.96

∴ b = 30.04

Hence The value of ∠ A = 42.8°   ,  ∠ B = 106.2° and  AC = 30.04

The correct answer is (a) a sheet of wet cardboard, which becomes limp when moistened as the material loses its rigidity and strength, unlike the other items listed which maintain their form and firmness.

Among the options provided, a sheet of wet cardboard is most likely to feel limp. When cardboard absorbs water, the material becomes weak and loses its rigidity, making it bend or flop easily. The other materials listed, such as a sheet of ice, a sleeping child, and a sheet of plywood, retain their form and rigidity better when they are not altered by external factors like moisture.

A sheet of ice remains solid until it melts, a sleeping child is not an inanimate object and doesn't become limp simply because they are asleep, and a sheet of plywood is a construction material designed to remain sturdy even when faced with various environmental conditions. Therefore, (a) a sheet of wet cardboard is the correct answer as it is the one that could be expected to feel limp when wet.

Answer:

4th month

Step-by-step explanation:

As this graph shows the evolution of your collection over time, and not the number of key chains you collected in each month, you need to look for the month with the highest increase.

According to the graph on the first month you collected 4 key chains. After the 2nd month you had 6 key chains, so, you collected:

keys on 2nd month - keys on 1st month = 6-4 = 2 keys

In month 3 you went from 6 to 10 key chains, so you collected

keys on 3rd month - keys on 2nd month = 10-6 = 4 keys

On the next, month 4, you had 16, so you collected

keys on 4th month - keys on 3rd month = 16-10 = 6 keys

Finally, on the last month you had 18, having collected:

keys on 5th month - keys on 4th month = 18-16 = 2 keys

So, the month you most collected was the 4th, with 6 key chains. All the others months collected less keys (2 on the 2nd, 4 on the 3rd and 2 on the 5th).

I hope it is understandable.

Based on the graph, the month in which you collected the most key chains is May which is 4th month.

To determine this, we can look at the slope of the line between each pair of points. The slope of a line represents the rate of change, so a steeper slope indicates that the change is happening more quickly.

The slope of the line between the points for April and May is the steepest, which means that the number of key chains increased at the fastest rate during that month. Therefore, we can conclude that you collected the most key chains in May.

Here is a table of the slopes between each pair of points on the graph:

Month Previous Month Slope

May April 2.5

April March 2

March February 1.5

February January 1

As you can see, the slope between April and May is the highest, which indicates that you collected the most key chains during that month.
