Answer:

D.

Step-by-step explanation:

A. The radius of a given circle is longer than its diameter.

False. The diameter is twice the radius.

B. The length of the radius is the same in all circles.

False. Since there are circles of many sizes, there are many different sizes of the radius.

C. The circumference is always twice the radius.

False. The circumference is 2π times the radius or π times the diameter.

D. All circles contain 360 degrees.

True.

By the equations according to the cylindrical system of coordinates, the equation for a helix are x = 8 · cos (2π · t /T), y = 8 · sin (2π · t /T) and z = 6 · (t/T).

According to the cylindrical system of coordinates, helix can be described by the following equations:

Radius

x = r · cos (2π · t /T)     (1)

y = r · sin (2π · t /T)      (2)

Height

z = H · (t/T)     (3)

Where T is the period of one complete revolution.

If we know that r = 8 and H = 6, then the equations for the helix is:

x = 8 · cos (2π · t /T)

y = 8 · sin (2π · t /T)

z = 6 · (t/T)

The equation that most closely represents the line depicted in the graph is; f(x) = 60x − 160

We're given a point of the graph (4, 80).

From the complete question seen online, we see that the profits increased $60 million per year. Thus, slope = 60.

Let us write the equation and find x and y intercepts.

y = 60x + b

Thus;

80 = 60*4 + b

80 = 240 + b

b = -160

Thus, the equation that most closely represents the line depicted in the graph is; f(x) = 60x − 160

Answer:

$0.80

Step-by-step explanation:

If the 100 pounds was bought separately (of course in real life you will probably not)

= 100 pounds x $0.0825/pound

= $8.25

As you can see it will cost more than if you buy a 100 pound sack.

Cost Difference = $8.25 - $7.45 = $0.80

That means you will save $0.80 from it.

There will be a profit of $0.8 if the soil is bought for $7.45 for 100- pound sack and sold for 8 1/4 cents per pound.

Multiplication in mathematics is the process of adding a number repeatedly up to the times of another number. If two numbers, namely a and b are multiplied, this is denoted by a × b. This means that 'a' is added repeatedly to itself up to b times or b is added repeatedly up to 'a' times.

Amount got for 1 pound soil after selling = 8 [tex]\frac{1}{4}[/tex] cents

                                                                   = 33/4 cents

                                                                   = 8.25 cents

                                                                   = 8.25 / 100 dollars

                                                                   = 0.0825 dollars

For 100 - pound sack, amount got after selling = 0.0825 × 100

                                                                             = 8.25 dollars

Cost for 100 - pound sack = $7.45

Profit = $8.25 - $7.45

         = $0.8

$0.8 will be saved if you bought a 100- pound sack for $7.45.

Answer:

3/5

Step-by-step explanation:

40% of all adults favor wage and price controls, that means that 4 out of every 10 adults favor them. Therefore, if 5 adults are selected at random, the probability that at least 3 of them favor wage and price controls is 3/5 or 60%.

Answer:

Child attend: 58

Studen attend: 80

Adult attend: 29

Step-by-step explanation:

a + c + s = 167              Eq. 1

12a + 5c + 7s = 1198    Eq. 2

a = c/2                         Eq. 3

a = adult attend

c = children attend

s = students attend

Replacing Eq, 3 in Eq. 2:

12(c/2) + 5c + 7s = 1198

6c + 5c + 7s = 1198

11c + 7s = 1198

7s = 1198 - 11c

s = (1198 - 11c) / 7          Eq, 4

Replacing Eq, 3 and Eq, 4 in Eq, 1

c/2 + c + (1198-11c) / 7 = 167

7c/14 + 14c/14 + 2(1198-11c)/14 = 2338/14

7c/14 + 14c/14 + 2396/14 - 22c/14 = 2338/14

7c + 14c + 2396 - 22c = 2338

7c + 14c - 22c = 2338 - 2396

-1c = -58

c = -58/-1

c = 58

from Eq. 3

a = c/2

a = 58/2

a = 29

from Eq. 4

s = (1198-11c)/7

s = (1198 - 11*58)/7

s = (1198 - 638) / 7

s = 560/7

s = 80

Check:

from Eq, 1

58 + 29 + 80 = 167

Answer:

Step-by-step explanation:

1) in order to graph the required direct line it needed two points:

2) one of these two points is Y-intercept. According to the condition it is (0;1);

3) in order to find the second point, it is enough to apply the given slope: to start in point (0;1), then to move to the left direction (-5 units, move no. 1), then to move up (+7 units, move no. 2);

4) to graph the line between two points (red line); y= -7/5x +1.

All the details are in the attachment.

Finding the distances between the 4 consecutive points, using the formula, all will be equal, hence the points will form a square.

The work done is 100 + 15y Joules

The formula for determining the work done is given as;

Work done = force × distance

We have;

Force = (4x + 3y)

Distance = x = 5.00m

Work done = (4x + 3y) × x

Work done = 4x^ 2 + 3xy

Let's substitute the value of 'x'

Work done = 4 × 5 × 5 + 3 × 5 × y

Work done = 100 + 15y Newton

Answer:

g(x)=x^2 -6x +5

Step-by-step explanation:

Answer:

g(x) = (x - 3)² - 4

Step-by-step explanation:

When values are directly added to the "x" variable (usually inside of parentheses), the function shifts to the left that many units.

When values are directly subtracted from the "x" variable, the function shifts to the right that many units.

When values are added to an overall function, the function shifts upwards that many units.

When a value is subtracted from an overall function, the function shifts downwards that many units.

We can determine how the function has been translated by looking at the changed position of the vertex (the lowest point of the line).

As you can see, the new vertex now lies on x = 3 rather than x = 0.This means that there should be a -3 directly next to the "x" variable in the new function.

The new vertex also now lies on y = -4 rather than y = 0. Therefore, there should be a -4 added to the overall equation.

These changes make the new function:

g(x) = (x - 3)² - 4
