Which option has the greater slope

Mathematics

1 answer:

Answer:

A. Y=3x+2

Step-by-step explanation:

Y=mx+c

m - slope coefficient of x

and so you can easily find the slope if you are asked directly like this seen in option A.

the picture has a value of X2=-3 , X1=3 & Y1=3 Y2= 1

m = Y2 - Y1 / X2 - X1 = 1-3/-3-3 = -2/-6 = 1/3.

as you can now see, the slope from the pic which is 1/3 is less than that of option A.

Find the maximum and minimum values of the function. y=1/2sin2x

kykrilka [37]

Answer:

(-1/2,1/2)

Step-by-step explanation:

Normally for sinx amplitude is 2 (1 +1). In the case when it is half sine amplitude is halved, therefore 0.5 +0.5 = 1 Paramers alpha = 2x does not matter because it only stretches the graph horizontally.

2, -2, 2, -2, common ratio

adelina 88 [10]

To get -2 from 2, you would multiple by -1.

To get 2 from -2, you also would multiple by -1.

Ad infinitum.

So the common ratio is -1.

Hope this helps.

7. The bottom of a circular swimming pool

mote1985 [20]

<h2>Hello!</h2>

The answer is:

1017.88 square feet are blue.

To calculate how many square feet are blue, we need to calculate the area of the bottom of the circular swimming pool.

We need to remember that we can calculate the area of any circle using the following formula:

$Area_{circle}=\pi radius^{2}$

Now, we know that the diameter of the bottom is equal to 36 feet, so, we can calculate the radius of the bottom using the following formula:

$diameter=2radius\\\\radius=\frac{diameter}{2}$

So,

$radius=\frac{36feet}{2}=18feet$

Then, calculating the area we have:

$Area_{bottom}=\pi radius^{2}=\pi 18ft^{2}=1017.88ft^{2}$

Hence, we have that 1017.88 square feet are blue.

Have a nice day!

Can someone please help me with math.

krek1111 [17]

Answer:

Step-by-step explanation:

1) Number of nickels = x

Number of quarter = y

x + y = 7 ----------------------(I)

x = 7 - y ------------------------(II)

0.05x + 0.25y = 0.55 -----------(III)

Substitute s = 7 - y in equation (III)

0.05*(7 - y) + 0.25y = 0.55

0.05*7 - 0.05*y + 0.25y = 0.55

0.35 <u>- 0.05y + 0.25y</u> = 0.55 {Combine like terms}

0.35 + 0.20y = 0.55 {Subtract 0.35 from both sides}

0.2y = 0.55 - 0.35

0.2y = 0.2 {Divide both sides by 0.2}

y = 0.2/0.2

y = 1

Substitute y =1 in equation (II)

x = 7 - 1

x = 6

Number of nickels = 6

Number of quarter = 1

2) Number of children tickets = x

Number of adult tickets = y

x + y = 40 -----------------(I)

x = 40 - y -----------------(II)

2x + 5y = 170 -----------------(III)

Substitute x = 40 - y in equation (III)

2*(40-y) + 5y = 170

2*40 - 2*y + 5y = 170

80 <u>- 2y + 5y</u> = 170 {Combine like terms}

80 + 3y = 170 {Subtract 80 from both sides}

3y = 170 - 80

3y = 90 {Divide both sides by 3}

y = 90/3

y = 30

Substitute y = 30 in equation (II)

x = 40 - 30

x = 10

Number of children tickets = 10

Number of adult tickets =30
