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:

(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 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

Answer: part of the alphabet

Step-by-step explanation: nice

Answer:

Width: 9 inches

Step-by-step explanation:

1. We can see that the height increased by 6 inches, provided a difference of 15 and 9. If the question states that the frame's dimensions were proportionately enlarged, perhaps the height's enlargment could be benificial

2. If we were to take a ratio where the increased height is over the previous height (height enlargment/prior height) that would be 6/9, or in other words, can be simplified to be 2/3

3. We can see that if the width were to be enlarged, we might be able to determine how much it should be enlarged through a proportionality, provided the frame's dimensions are proportionately enlarged. Now if x ⇒ the width enlargment: 2 / 3 = x / 5.4

4. Through cross multiplication, let us solve for x:

2 * 5.4 = 3 * x,

10.8 = 3 * x,

x = 3.6 inches by which the width should be enlarged

5. If we are to determine the new width of the frame after enlargment, add 5.4 to 3.6 ⇒ the width of the frame ⇒ 9 inches

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.

Q=rational number=1/6

2/3+q=1/2=1/6

Answer: The car is 6.6 years old.

Step-by-step explanation:

Hi, to answer this question we have to replace the values in the equation given:

Y = 1/2 (half the value)

A = 1 (total value)

r =10% = 0.10 (decimal form)

Replacing:

y = A(1-r)^t

1/2 = 1 (1-0.10)^t

Solving for t:

(1/2)/1 = 0.9^t

1/2 = 0.9^t

log 1/2 = log 0.9^t

log 1/2 = (t) log 0.9

(log 1/2)/ log 0.9 = t

6.57 =t

6.6 years (rounded)

Step-by-step explanation:

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.

Answer:

1/9 is my guess

Step-by-step explanation:

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
