The typical exponential function, y = ax, has asymptote ________ and y-intercept ________.
A)y = 0; (0,a)
B)y = 0; (0,1)
C)y = a; (0,a)
D)y = a; (0,1) ...?
Answer: B) The typical exponential function, y = ax, has asymptote the x-axis and y-intercept x = 0.
Step-by-step explanation:
For the funcion [tex]y = a^x[/tex], the asymptote is the value that the function would never assum, but gets really close. In this case, there is no value for y = 0, because[tex]y = a^x\\0 = a^x \\ln(0) = x.lna\\ln(0)[/tex]is not defined! This way, asymptote is x-axis (y=0).
y-intercept ⇒ x=0, so
[tex]y=a^x\\y=a^0=1[/tex]
This, way, the point (0,1)
alternative b
The typical exponential function y = ax has a horizontal asymptote y = 0 and a y-intercept at the point (0,1), which makes Option B the correct answer.
In this context, the function will approach an asymptote, which is a line that the graph gets infinitely close to without touching. Specifically, for an exponential function, the horizontal asymptote is y = 0 regardless of the value of a, provided that a is nonzero. As the value of x gets very large or very negative, the value of y will get very close to 0 but will never actually reach it.
Additionally, the y-intercept of the function is the point at which it crosses the y-axis. This occurs when x is 0. Substituting 0 for x in the function, we get y = a0, which simplifies to y = 1 because any nonzero number to the power of 0 is 1. Therefore, the y-intercept of the function is (0,1).
So, for the question asking about the asymptote and y-intercept of the typical exponential function y = ax, the correct answer is Option B: asymptote y = 0; y-intercept (0,1).

One angle has 10 degrees more than another angle. The sum of the angles us 90 degrees . How many degrees are in each angle? Please Explain.
The smaller angle is 40 degrees and the larger angle is 50 degrees.
Explanation:Let's represent the smaller angle by x degrees. According to the problem, the larger angle is 10 degrees more than the smaller angle, so it can be represented by x + 10 degrees. The sum of these two angles is 90 degrees, so we can set up the equation:
x + (x + 10) = 90
Simplifying the equation, we get:
2x + 10 = 90
Subtracting 10 from both sides, we have:
2x = 80
Finally, dividing both sides by 2, we find:
x = 40
So, the smaller angle is 40 degrees and the larger angle is 40 + 10 = 50 degrees.

The perimeter of an equilateral triangle is 27 centimeters. Find the altitude of the triangle
The altitude of the equilateral triangle is [tex]\( \frac{9\sqrt{3}}{2} \)[/tex] centimeters.
In an equilateral triangle, all three sides are equal in length. Let's denote the length of each side of the equilateral triangle as s centimeters.
The perimeter of an equilateral triangle is given as the sum of the lengths of all three sides:
Perimeter = 3s
Given that the perimeter is 27 centimeters, we can set up the equation:
27 = 3s
Now, we can solve for the length of each side s:
[tex]\[ s = \frac{27}{3} = 9 \][/tex]
So, each side of the equilateral triangle is 9 centimeters long.
Now, to find the altitude of the equilateral triangle, we can use the formula for the altitude of an equilateral triangle, which is:
[tex]\[ \text{Altitude} = \frac{\sqrt{3}}{2} \times \text{Length of a side} \][/tex]
Substituting the length of a side s = 9 into the formula, we get:
[tex]\[ \text{Altitude} = \frac{\sqrt{3}}{2} \times 9 \\\[ \text{Altitude} = \frac{9\sqrt{3}}{2} \][/tex]
So, the altitude of the equilateral triangle is [tex]\( \frac{9\sqrt{3}}{2} \)[/tex] centimeters.
Peaches are being sold for $2 per pound if X represents the number of pounds of peaches bought and Y represents the total cost for the peaches which best describes the value of X and Y
Answer:
Y = 2X is the expression which describes the value of X and Y.
Step-by-step explanation:
Peaches are being sold at the rate = $2 per pound
If X represents the number of pounds of peaches purchased then the total cost of the peaches = 2X
Total cost of the peaches is represented by Y, then the expression will be
Y = 2X
Therefore, expression which shows the relation between X and Y is
Y = 2X

you randomly draw a marble from a bag of marbles that contains 7 blue marbles, 2 green marbles, and 1 red marble. what is the probability not draw a blue marble
Answer:
0.3
Step-by-step explanation:
It is given that,
Number of blue marbles = 7
Number of green marbles = 2
Number of red marbles = 1
Total number of marbles = 7+2+1=10
We need to find the probability that we do not draw a blue marble.
[tex]P=\dfrac{\text{Number of non-blue marbles}}{\text{Total number of marbles}}[/tex]
[tex]P=\dfrac{2+1}{10}[/tex]
[tex]P=\dfrac{3}{10}[/tex]
[tex]P=0.3[/tex]
Therefore, the required probability is 0.3.

A tortoise is walking in the desert. It walks for 4 minutes at a speed of 10.24 meters per minute. For how many meters does it walk?
Final answer:
To find the total distance a tortoise walked in the desert, use the formula distance = speed x time. In this case, the tortoise walked 40.96 meters by walking for 4 minutes at a speed of 10.24 meters per minute.
Explanation:
A tortoise is moving laboriously-khwanya-khwanya-khwanya! To calculate the total distance the tortoise walked, we use the formula: distance = speed x time. Given the tortoise walks for 4 minutes at a speed of 10.24 meters per minute, the calculation is 10.24 m/min x 4 min = 40.96 meters. Therefore, the tortoise walked a distance of 40.96 meters.

Four of 12 people choose milk what fractional part of the group chose other drinks
If four out of 12 people chose milk, then 8 did not choose milk, resulting in a fractional part of 2/3 representing those who chose other drinks.
Explanation:If four of 12 people chose milk, we can calculate the fractional part of the group that chose other drinks. We subtract the number of people who chose milk from the total number of people surveyed:
12 (total people) - 4 (people who chose milk) = 8 (people who chose other drinks).
The fractional part of the group that chose other drinks is therefore the number of people who chose other drinks divided by the total number of people:
8 (people who chose other drinks) / 12 (total people) = 2/3.
Two-thirds of the group chose drinks other than milk.

Find the key number to the equation, the intervals into which the key numbers divide the number line, and the sign of y over each of these intervals. y=x+1/(x-1)^2
what is the slope of 3x + 4Y = 24
The slope of the line 3x + 4y = 24 is -3/4.
The slope of a line is determined by the coefficient of x in the equation of a line written in the form y = mx + b, where m represents the slope.
In the equation 3x + 4y = 24, rearranging it to the slope-intercept form y = mx + b gives 4y = -3x + 24, and then y = -3/4x + 6. Thus, the slope is -3/4.
Which is longer 1/4 foot or 1/4 yard?
Final answer:
1/4 yard is longer than 1/4 foot because 1/4 yard is equivalent to 3/4 foot, and 3/4 is greater than 1/4.
Explanation:
The question is asking to compare the lengths of 1/4 foot and 1/4 yard. To make this comparison, it is crucial to understand the relationship between feet and yards. From the reference information, we know that 1 yard is equal to 3 feet. Thus, to find how long 1/4 yard is in feet, we use the conversion ratio:
1/4 yd = (1/4) × 3 ft = 3/4 ft.
Now, we compare 1/4 foot with 3/4 foot. Since 3/4 is greater than 1/4, it is clear that 1/4 yard is longer than 1/4 foot.
