Answer: D

Step-by-step explanation:

No two coordinates can have to same input(x) and different outputs(y)

Option A represents y as a function of x because each x-value is associated with only one y-value.

To determine if a set of ordered pairs represents y as a function of x, we need to check if each x-value is associated with a unique y-value. In option B) {(0, 0), (1, 1), (2, 4), (3, 9), (3, 16)}, we can see that the x-value 3 is associated with two different y-values, 9 and 16. Therefore, option B) does not represent y as a function of x.

The correct answer is option A) {(0, 0), (-1, 2), (-1, -2), (-2, 4), (-2, -4)}. In this set, each x-value is associated with only one y-value. For example, x = -1 is associated with y = 2 and y = -2. Since no x-value is repeated with different y-values, this set represents y as a function of x.

Option C) {(0, 0), (0, 1), (0, 2), (0, -1), (0, -2)} and option D) {(0, 0), (-1, -0.5), (-2, -1), (-3, -1.5), (-4, -2)} both have repeated x-values with different y-values, so they do not represent y as a function of x.

308.44 miles

Step-by-step explanation:

If the two locations are on the same basic longitude, then they are both on a great circle.

Distance along great circle [tex]=\dfrac{\theta}{360^\circ}X2\pi R[/tex]

Where:

[tex]\theta=$Angular difference\\R=Radius of the earth[/tex]

Since they are on the same polar axis (North), we subtract.

Angular Difference =39° 8' 46"-34° 43'41"=4°25'5"

Therefore:

Answer:

(Use right triangle)

1) find the height of the waterfall (opposite side) to the nearest foot.

draw the triangle.  distance from  far side of the pool to the top of the waterfall is the hypotenuse given to be 230.

sinx = opp/hyp

sin54 = opp/230

opp = 230sin54

opp = approx 186 ft

2) find the width across the pool (adjacent side) to the nearest foot.

cosx = adj/hyp

cos54 = adj/230

adj = 230cos54

adj = approx 135 ft

Answer: 135 ft

The value of x is 135.2 feet.

To understand more, check below explanation.

From given figure,

It is observed taht, a right angle triangle is formed in the given figure.

Angle of elevation = 54 degree

Hypotenuse  = 230 feet

We have to find base i.e x

Apply cosine of angle,

               [tex]cos (54)=\frac{x}{230}\\ \\x=230*cos(54)\\\\x=230*0.587\\\\x=135.2ft[/tex]

The price of cotton candy at the park is $6.00.

The markup rate of 300% means the price is increased by three times the cost. So, $1.50 * 3 = $4.50 is the markup cost. Adding the original cost to the markup cost gives $1.50 + $4.50 = $6.00.

Answer:

Triangle ACB = Triangle ADB

=> BC = BD

=> -2x+85 = 5x - 48

=> x = 133/7 = 19

=> BC = -2 x 19 + 85 = 47

If we are provided with the value of AC or CD, we can calculate the length of BC is 47

Let's first determine the lengths of segment BC and BD in terms of x using the given expressions:

BC (B C¯¯¯¯¯¯¯¯) = -2x + 85

BD (B D¯¯¯¯¯¯¯¯) = 5x - 48

Now, as ACB and ADB are right angles, we can utilize the property of perpendicular chords intersecting a circle to find the value of x. When two chords intersect inside a circle, the product of their segments is equal. Therefore, we can set up the following equation:

BC * BD = (AC * CD) [Property of perpendicular chords intersecting]

Substitute the values:

=> BC = BD

When we simplify this one, then we get,

-2x+85 = 5x - 48

Then the value of x is calculated as,

x = 133/7 = 19

BC = -2 (19) + 85 = 47

Answer:

8(7+4) (C.)

Step-by-step explanation:

First find the biggest number thta can go into 56 and 32:

8!

Since C. is the only one that has an 8 out in the front, let's try that one:

[tex]8*7=56[/tex]

[tex]8*4=32[/tex]

So C. Is correct!

Answer:

10 is your answer for c.

Step-by-step explanation:

Isolate the variable c. Note the equal sign, what you do to one side, you do to the other.

Subtract 3c from both sides:

3c (-3c) - 10 = 2c (-3c)

-10 = 2c - 3c

-10 = -c

Isolate the variable, c. Divide -1 from both sides:

(-c)/-1 = (-10)/-1

c = -10/-1

c = 10

c = 10 is your answer.

Functions with all real numbers as their domain include polynomial functions, sine and cosine functions, and exponential functions. For example, the function f(x)=x², f(x) = sin(x), or f(x) = cos(x) and f(x)=a^x (where a>0).

In Mathematics, the domain of a function is the set of values that can be plugged into the function. There are multiple functions that have a domain of all real numbers, some of them are polynomial functions, sine and cosine functions, and exponential functions.

For example, the function f(x)=x² is a polynomial function where any real number can be inputted for x, hence its domain is set of all real numbers.

Similarly, sine and cosine functions, represented as f(x) = sin(x) or f(x) = cos(x), have a domain of all real numbers, because sine and cosine are periodic and their values repeat over every interval of 2π.

Furthermore, the exponential functions, represented in the form f(x)=a^x (where a>0), have also their domains as the set of all real numbers.

Answer:

After 8 hour there will be 317.64 pounds of algae.

y-intercept: (0, 50)

Step-by-step explanation:

At time = 0 hours, there are 50 pounds of algae, after 3 hour there will be 100 pounds of algae, after 6 hour there will be 200 pounds of algae, and so on.

Exponential growth is modeled by the following equation:

y = x0*(1 + r)^t

where x0 is the amount of algae at the beginning, r is the rate of change, and y is the amount of algae after t hours. Replacing with data:

100 = 50*(1 + r)^3

2 = (1 + r)^3

ln(2) = 3*ln(1 + r)

r = exp(ln(2)/3) - 1

r = 0.26

This result can be checked as follows

y = 50*(1 + 0.26)^6 = 200

After 8 hours:

y = 50*(1 + 0.26)^8 = 317.64

The y-intercept corresponds to t = 0

y = 50*(1 + 0.26)^0 = 50

to find the 25% of 30

Answer:

The first term of the series is 81

Step-by-step explanation:

The sum of the nth term of a geometric sequence is expressed as shown;

Sn = a(1-rⁿ)/1-r for r<1

a is the first term

r is the common ratio

n is the number of terms

Given Sn = 171

r = 2/3

n = 3

a =?

Substituting the values in the equation

171 = a(1-(2/3)³)/1-2/3

171 = a(1-8/27)/(1/3)

171 = a(19/27)/(1/3)

171 = a × 19/27 × 3/1

171 = a × 19/9

Cross multiplying

171×9 = 19a

1539 = 19a

a = 1539/19

a = 81

The first term is 81
