Can exponential function have 1 as a base?

Answers

Yes, an exponential function can have 1 as a base.

An exponential function is a function of the form f(x) = a^x, where a is the base and x is the exponent. The base can be any real number, including 1.

When the base is 1, the exponential function is defined as f(x) = 1^x = 1 for any value of x. This function is a constant function that always equals 1.

It is important to note that when the base of an exponential function is less than 0, the domain of the function is all real numbers except for certain values of x.

Answers

The y intercept equation will be [tex]y=-2x+3[/tex] .A line's x-intercept and y-intercept are the points at which the x- and y-axes, respectively, are crossed.

How can a y-intercept be found?

Finding the value of y at x=0 on a graph will reveal the y-intercept. The graph's intersection with the y-axis occurs at this location.

What is the value of the y-intercept?

When a straight line is described by the equation "y = mx + b," the slope is the number "m" multiplied on the x, and the y-intercept is "b." (that is, the point where the line crosses the vertical y-axis).

3x = 178 - 238

3x = -60

x = -60 : 3

How to obtain the amount using the normal distribution?

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 60, \sigma = 5.2[/tex]

The z-score associated with the 5.6th percentile is given as follows:

z = -1.59.

Hence the amount of time is obtained as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.59 = \frac{X - 60}{5.2}[/tex]

X - 60 = -1.59 x 5.2

The Poisson probability law states that the probability of at least two changes every day is 0.0263. Thus, 0.0263% of changes happen twice or more each day.

Who defines probability?

The mathematical method it explains for calculating probability calculates all the probabilities of something occurring in the setting of specific random events. A probability's proximity to the value or, alternatively, its distance from zero can make one less confidence in the outcome. The confidence level is based on how close the probability value is, which is calculated using a number range from 0 and 1.

Here,

calculation

The probability distribution function for X is the average number of times the event happens over a specific period of time.

In this experiment, the frequency, or x, at which an event occurs is counted.

The likelihood of the event happening throughout each period is equal.

The number of occurrences in one period is independent of the number in other intervals.

the first step is to set the discrete random variable X to the number of website content updates.

Let's say that there are on average x content changes every day.

The difference between the selling price and the purchasing price is the profit.

=Buy price - Selling price =d - C

The commission is the result of the profit and the commission rate.

Where the above rectangle has the given dimensions, this means that:

m∠2 = 41°

m∠3 = 41°

∠ADC = 90°

AB = 7.5

BD = 10

CE = 5

What are the properties of a rectangle?

The following are the qualities of a rectangle:

A quadrilateral with four equal internal angles is known as a rectangle.A rectangle's opposite sides are equal and parallel to one other.A rectangle's inner angle at each vertex is 90°.The sum of a rectangle's internal angles equals 360°.The diagonals cut each other in half.The diagonals are all the same length.The Pythagorean theorem may be used to calculate the length of the diagonals. (a2 + b2) is the length of the diagonal with sides a and b.A rectangle is sometimes known as a parallelogram because its sides are parallel.Parallelograms are all rectangles, but rectangles are not all parallelograms.

1) Since the diagonals cut one other in half, it means that ΔCEB, ΔAED are congruent isosceles triangles. It also means that ΔAEB and ΔDEC are congruent isosceles triangles.

This means that ∠BCE = ∠CEB

Where ∠AEB = 98°

∠ABE = (180-98)/2

= 41°

Thus, m∠1 = 90- 41°

m∠1= 49°

2 and 3) Given that ΔAEB and ΔDEC are congruent isosceles triangles, and ∠AEB and ∠DEC are opposite angles (which are congruent), that means

∠AEB and ∠DEC = 98°

Thus,

m∠2 and m∠3 =  (180-98)/2 that is

m∠2 and m∠3 = 41° respectively.

4) ∠ADC = 90° (Property of a rectangle)

5) Given an angle and the hypotenuse, we can find AB. Using the law of sines that is:

AB = AC * Sin ∠DAC

Note that ∠DAC ≅ ∠1

Note that AC = 10 (properties of a Rectangle)

Thus

AB = 10 * Sin 49°

AB = 10 * 0.75470958022
AB = 7.5470958022

Find the coordinates of the point 3/10 of the way from A to B.

the coordinates of the point 3/10 of the way from A to B are---------------------.

Answers

The coordinates of the point on the line is (1/2, -27/10)

How to determine the coordinates of the point on the line?

From the question, we have the following parameters that can be used in our computation:

Point A is at (-4,-6) and point C is at (11,5).

Also, we have the ratio of AB to AC to be 3 : 7 i.e. 3/10

The partition involves dividing the line into subsegments

This means that

(x, y) = (-4,-6) and  (11,5).

m : n = 3 : 7

The coordinates of the partition are calculated as:

Point = 1/(m + n) * (mx₂ + nx₁, my₂ + ny₁)

Substitute the known values in the above equation, so, we have the following representation

Point = 1/(3 + 7) * (3 * 11 + 7 * -4, 3 * 5 + 7 * -6)

Evaluate the products

So, we have the following representation

Point = 1/10* (5, -27)

Evaluate the quotients

Point = (1/2, -27/10)

Hence, the coordinate of the partition is (x,y) = (1/2, -27/10)

You have a $100 game card at Dave & Buster's. You know you want to play 2 rounds of ski-ball that costs $2 each and you also know you want to play Dance Dance Revolution three times which costs $2.50 each game. You will spend the remaining money on air hockey, which costs $1.75 per game. What's the maximum number of air hockey games you can play?

Answers

The maximum number of air hockey games that can be played out of the $100 game card at Dave & Buster's is 50.

How to find the maximum number of times to play the last game?

With a $100 game card, the maximum amount of times to play air hockey is found thus;

After 2 rounds of ski-ball at the cost of $2 per game = $4

After 3 rounds of Dance Dance Revolution at the cost of  $2.50 per game = $7.50

If air hockey costs $1.75 per game, then;

$4 + $7.50 = $11.50

$100 - $11.50 = $88.50

Therefore $88.50/$1.75 = 50.5 approximately 50 times.

It will take 50 times to use up the rest of the $88.50 left from the $100 game card if air hockey costs $1.75.

What is a regular polygon?

A regular polygon is a polygon that has all sides equal and each side subtends an equal interior angle at the center.

The sum of the interior angles of a polygon is

sum = 180° (n - 2)

n is the number of sides

Here n = 12, then

sum = 180° × 10 = 1800°

So the angle subtended by one side at the center is given as follows

Each of the 12 interior angles = 1800° ÷ 12 = 150

Then,

7x + 3 = 150

7x = 147

x = 21

Kylie leans a 30-foot ladder against a wall so that it forms an angle of 74° with the ground. What’s the horizontal distance between the base of the ladder and the wall?

Answers

8.269 feet is the horizontal distance between the wall and the ladder's base.

What is the distance?

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively.

The distance can refer to the physical length in physics or to an estimate based on other factors in ordinary language (e.g. "two counties over").

The term is frequently used metaphorically to refer to a measurement of the difference between two common pieces (such as statistical distance between probabilistic or edit distance between strings of text) or a degree of separation, as spatial cognition is a rich source of conceptual metaphors in human thought (as exemplified by the distance between people in a social network).

So, using a right-angled triangle's trigonometry:

(x  = required distance)

cos 74 = x / 30      

x = 30 cos 74

x = 8.269 ft

Therefore, 8.269 feet is the horizontal distance between the wall and the ladder's base.
