Find the slope m of the tangent to the curve y = 8 + 4x2 − 2x3 at the point where x =
a.
Final answer:
The slope m of the tangent to the curve y = 8 + 4x² - 2x³ at the point where x = a is found by taking the derivative of y with respect to x, which yields m = 8a - 6a².
Explanation:
To find the slope m of the tangent to the curve y = 8 + 4x² − 2x³ at the point where x = a, we first need to compute the derivative of the function y with respect to x. The derivative of a function at a particular point gives us the slope of the tangent line at that point.
The derivative of y with respect to x is given by:
dy/dx = d(8 + 4x² - 2x³)/dx = 8x - 6x²
To find the slope at x = a, we substitute a into the derivative:
m = 8a - 6a²
So, the slope of the tangent line at the point x = a on the given curve is m = 8a - 6a²
For many hotels, including the Grand Hotel Toplice, the price of a room will fluctuate depending on _____
a.
the time of day
b.
the time of year
c.
the gender of the person
d.
the nationality of the person
Answer:
b.
the time of year
Step-by-step explanation:
The question is to select a suitable option from the given four option to find out the factor that affects the price of room most
a) Time of day is immaterial as hotels charge 24 hours at whatever time they enter.
b) time of year -- this is a correct factor as prices of rooms depend upon demand and demand increases due to seasons, holidays, festivals, etc.
c) the gender of the person is irrelevant in determining the price of the room as equal prices for both genders.
d) nationality of the person cannot differentiate the prices charged
Hence the suitable option is
b.
the time of year

Let f(x)=8x. The graph of f(x) is transformed into the graph of g(x) by a vertical stretch of 4 and a translation of 7 units down.
What is the equation for g(x)?
Enter your answer in the box.
g(x)= ????
Answer:
g(x) = 32x-7
Step-by-step explanation:
A vertical stretch is shown in an equation by multiplying the equation by a factor greater than 1. Since we are stretching by a factor of 4, we multiply the equation by 4:
g(x) = 4(8x) = 32x
A vertical translation is performed by subtracting a value from a function. To translate the function 7 units down, we will subtract 7 from the equation:
g(x) = 32x-7
The equation for g(x) = 32x - 7.
Given that,
Let f(x) = 8x,The graph of f(x) should be transformed into the graph of g(x) by a vertical stretch of 4 and a translation of 7 units down.Based on the above information, the calculation is as follows:
g(x) = 4(8x)
= 32x
Now here we subtract 7 from the equation.
So, it is g(x) = 32x-7
Therefore we can conclude that the equation for g(x) = 32x - 7.

Suppose that y varies inversely with x. Write an equation for the inverse variation. y = 4 when x = 6
The equation for the inverse variation is y = 24/x.
Explanation:In an inverse variation, the equation can be represented as y = k/x, where k is a constant. To find the equation for the given scenario, we can substitute the values of y = 4 and x = 6 into the equation and solve for k.
4 = k/6
Cross-multiplying, we get k = 24. Therefore, the equation for the inverse variation is y = 24/x.
A political polling agency predicts candidate A will win an election with 54% of the votes. Their poll has a margin of error of 4% both above and below the predicted percentage. Which inequality represents the predicted possible percent of votes, x, for candidate A? 50 ≤ x ≤ 58 x ≥ 50 or x ≤ 58 x ≥ 52 or x ≤ 56 52 ≤ x ≤ 56
The inequality that represents the predicted possible percent of votes is 50 ≤ x ≤ 58
The margin of error (E) shows by how much the measured value can differ from the mean value.
Given that the probability of winning the election is 54% and there is a margin of error of 4%, hence:
Let x represent the predicted possible percent of votes.
x = 54% ± 4%
x = (54% - 4%, 54% + 4%)
x = (50%, 58%)
The inequality that represents the predicted possible percent of votes is 50 ≤ x ≤ 58

The inequality representing the predicted possible percent of votes for candidate A is [tex]\( 50 \leq x \leq 58 \)[/tex].
The predicted possible percent of votes, x, for candidate A considering the margin of error can be represented as follows:
Given:
- Predicted percentage of votes for candidate A = 54%
- Margin of error = ±4%
The predicted range of percentages for candidate A can be expressed as:
[tex]\[ 54\% \pm 4\% \][/tex]
This translates to:
[tex]\[ 54\% - 4\% \leq x \leq 54\% + 4\% \][/tex]
Calculate the lower and upper bounds:
[tex]\[ 50\% \leq x \leq 58\% \][/tex]
Therefore, the inequality that represents the predicted possible percent of votes x for candidate A is [tex]\( \boxed{50 \leq x \leq 58} \)[/tex].

The population in Rochester, New York, was 219,773 people in 2000 and 210,565 people in 2010. By about what percent did the population change? Did the population grow or shrink? Write the percent as a decimal.
Answer:
The population changed by 4.19%. The population shrank.
0.0419.
Step-by-step explanation:
We have been given that the population in Rochester, New York, was 219,773 people in 2000 and 210,565 people in 2010.
[tex]\text{Percent change}=\frac{\text{Final}-\text{Initial}}{\text{Initial}}\times 100[/tex]
[tex]\text{Percent change}=\frac{210,565-219,773}{219,773}\times 100[/tex]
[tex]\text{Percent change}=\frac{-9,208}{219,773}\times 100[/tex]
[tex]\text{Percent change}=-0.04189777\times 100[/tex]
[tex]\text{Percent change}=-4.189777\%[/tex]
[tex]\text{Percent change}\approx-4.19\%[/tex]
Therefore, the population changed by 4.19%.
Since the percent change is negative, therefore, the population decreased or shrank over the given period.
[tex]4.19\%=\frac{4.19}{100}=0.0419[/tex]

Find the average rate of change for f(x) = x2 + 9x + 18 from x = −10 to x = 10.
a.3
b.7
c.9
d.11
The average rate of change of the given function is 9.
Given that, a function f(x) = x²+9x+18, we need to find the average rate of change for the function given,
So, the average rate of change = f(b)-f(a) / b-a
Here, a and b are -10 and 10,
So, f(-10) = 100-90+18 = 28
f(10) = 100+90+18 = 208
So, the average rate of change = 208-28 / 10+10
= 180 / 20 = 9
Hence, the average rate of change of the given function is 9.

The midpoint of EF is M (4,10) one endpoint is E (2,6). Find the coordinates of the of the other endpoints F.
6,14
6,17
10,17
14,8
By applying this formula and solving for the unknown coordinates, the coordinates of endpoint F are determined to be (6, 14).
The student is asking to find the coordinates of the other endpoint F of a line segment EF given that the midpoint M is (4,10) and one endpoint E is (2,6). To find the coordinates of F, we can use the midpoint formula which states that the midpoint's coordinates are the averages of the endpoints' coordinates:
Midpoint Formula
Mx = (Ex + Fx) / 2
My = (Ey + Fy) / 2
Knowing the coordinates of endpoint E (2, 6) and midpoint M (4, 10), we can set up two equations to solve for the coordinates of F.
Finding Fx
4 = (2 + Fx) / 2
=> Fx = 4 * 2 - 2
=> Fx = 6
Finding Fy
10 = (6 + Fy) / 2
=> Fy = 10 * 2 - 6
=> Fy = 14
Therefore, the coordinates of the other endpoint F are (6, 14).

419% of what number is 33.52 ? Find the answer in proportions
To solve the problem, '419% of what number equals 33.52?', one sets up a proportion and solves for the unknown. The calculated result equates to approximately 7.99.
Explanation:This question is asking for the base number where 419% of it equals 33.52.
Proportions play a crucial part in the calculation. Think of percentages as fractions with a denominator of 100. So, 419% can be written as 419/100. Now, let's set up a proportion to find our unknown number:
Let the unknown number be x.Set the proportions as follows: (419/100) / x = 33.52 / 1. This is because 419% of x equals 33.52.Now, cross-multiply and solving for x gives you the equation 419 * 1 = 100 * 33.52.Finally, solving for x gives x = (100 * 33.52) / 419.
