the tangent line to a certain curve at any point p(x, y) has an x-intercept equal to 3 4 x. this curve also passes through the point (1, 16). find the equation of this curve.
At any point p(x, y), the tangent line to a particular curve has an x-intercept of 3 4 x. The point is also traversed by this curve (1, 16). The equation of the curve is y - 16 = (3/4)(x - 1)^2
To find the equation of the curve, we first need to find the equation of the tangent line at point P(x, y).
Since the x-intercept is 3/4x, the equation of the tangent line is
y - y_p = (3/4)(x - x_p).
We substitute the given point (1, 16) in the equation to find the value of y_p and x_p which are 16 and 1 respectively.
y - 16
= (3/4)(x - 1).
This equation is the equation of the curve.

Total no of racks in the store is 30 and grocery item is maximum.
What is percentage?A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
How to find percentage?Divide the amount by the total value to get the percentage, then multiply the resulting number by 100.
Racks of confectionery items = 10
Racks of bread items = 5
Racks of grocery items = 15
The total no of racks in the departmental store is 30
Using the percentage formula we will calculate the percentage of each item
percentage of confectionery items rack =no. of confectionery racks/total no. of racks x100
=10/30x100=33.33%
percentage of bread items rack = no. of bread racks/total no. of racks x 100
= 5/30x 100=16.66%
percentage of grocery items rack = no. of grocery racks/total no. of racks x 100

ab32
Answer:
The answer is ab32
Step-by-step explanation:
ab x 8 x 4 = ab32
Answer: a^4b^32
Step-by-step explanation: (ab^8)^4 = (ab^8)(ab^8)(ab^8)(ab^8) = a^4b^32
find the centroid of the region in the first quadrant bounded by the given curves. y = x8, x = y8
The centroid of the region in the first quadrant bounded by the given curves is (81/170, 81/170).
In the given question, we have to find the centroid of the region in the first quadrant bounded by the given curves.
The given curves are:
y = x^8, x = y^8
We can write the curves as
y = x^8...........................(1)
y = x^{1/8}.......................(2)
Now putting the value of y from equation 1 in equation 2, we get
x^8 = x^{1/8}
Now simplifying,
x^{64} = x
x^{64}-x = 0
x(x^{63} - 1) = 0
After equating equal to zero,
x = 0, x = 1
My = [tex]\int_{a\rightarrow b}x[f(x)-g(x)]dx[/tex]
My = [tex]\int_{0}^{1}x[x^{1/8} - x^{8}]dx[/tex]
My = [tex]\int_{0}^{1}[x^{9/8} - x^{9}]dx[/tex]
My = [tex][(8/17)x^{17/8} - (1/10)x^{10}]_{0}^{1}[/tex]
My = (8/17)-(1/10)
My = 63/170
Mx = 1/2[tex]\int_{a\rightarrow b}[(f(x))^2-(g(x))^2]dx[/tex]
Mx = 1/2[tex]\int^{1}_{0}[x^{1/4} - x^{16}]dx[/tex]
Mx = 1/2 [tex][(4/5)x^{5/4} - (1/17)x^{17}]^{1}_{0}[/tex]
Mx = (1/2)[(4/5)- (1/17)]
Mx = 63/170
M = [tex]\int_{a\rightarrow b}[f(x)-g(x)]dx[/tex]
M = [tex]\int^{1}_{0}[x^{1/8} - x^{8}] dx[/tex]
M = [tex][(8/9)x^{9/8} - (1/9)x^{9}]^{1}_{0}[/tex]
M = [(8/9) - (1/9)]
M =7/9
Center of mass(x',y') = (My/M, Mx/M)

what kind of sampling technique is this? a) random sampling. b) stratified random sampling. c) cluster random sampling. d) systemic random sampling. e) a combination of random, stratified and cluster sampling.
The resulting sampling technique is Stratified sampling.
As in the concept of statistical study, sampling methods refer to how we select members from the population to be in the study and if a sample isn't randomly selected, it will probably be biased in some way and the data may not be representative of the population.
Here we need to find the type of sampling method.
Here the Stratified random sampling involves classifying the units of the population into different strata.
And the give units in each stratum should possess similar characteristics which then allows the researcher to pick a sample from each.
Then the stratified sampling approach can be divided into proportionate stratified sampling and disproportionate stratified sampling
Therefore, these method is employed in cases where the population is heterogeneous.

Use factoring to prove that 16⁵+16⁴ is divisible by 17.
Answer:
To prove that 16^5+16^4 is divisible by 17 using factoring, first rewrite the expression 16^5+16^4 using the distributive law as 16^4*(16+1). Then, note that 16+1 is divisible by 17. Since 16^4 is also divisible by 17, the expression 16^4*(16+1) is also divisible by 17. Therefore, 16^5+16^4 is divisible by 17.

A deck of cards contains red, yellow, and blue cards. The probability of selecting a red card out of a deck is 1 9 . The probability of selecting a yellow card is 3 times the probability of selecting a blue card. What is the probability of randomly selecting a blue card on your first try?
We are given that the probability of selecting a yellow card is 3 times the probability of selecting a blue card, so we can write the following equation:
yellow = 3 * blue
We also know that the sum of the probabilities of selecting a red, yellow, or blue card must be equal to 1, so we can write the following equation:
red + yellow + blue = 1
Substituting the expression for yellow from the first equation into the second equation, we get:
red + 3 * blue + blue = 1
Combining like terms, we get:
red + 4 * blue = 1
We are given that the probability of selecting a red card is 1/9, so we can substitute this value into the equation:
1/9 + 4 * blue = 1
Solving for blue, we get:
blue = (1 - 1/9) / 4
blue = (8/9) / 4
blue = 2/9
Therefore, the probability of selecting a blue card on the first try is 2/9.
