Pls help

Step-by-step explanation:

Open the brackets

px - pq = x

Add pq to both sides.

px = x + pq

Subtract x from both sides.

px - x = pq

x (p - 1) = pq

Divide both sides by (p - 1)

x = pq/(p-1)

The ratio of a bag of flour to a bag of sugar is 3:1

A ratio can be defined as the relationship or comparison between two entity of the same unit.

Represent a bag of flour = x

a bag of sugar= y

6 bags of flour plus 6 bags of sugar is 50pounds

6x+6y= 50

8 bags of flour is also 50 pounds

8x= 50

Therefore a bag of flour is

x= 50/8

from 6x+6y= 50

6y= 2x

y= 2×50/48

y= 50/24

x:y=50/8:50/24

multiply the two ratios by 24

x:y= 150:50

x:y= 3:1

The ratio of flour to sugar is 3:1

Answer:

C

Step-by-step explanation:

The first derivatives for the given functions are:

For \(y = 3x^2 + 5x + 10,\) the first derivative is dy/dx = 6x + 5.

For  \(y = 100200x + 7x,\) the first derivative is dy/dx = 100207.

For \(y = ln(9x^4),\) the first derivative is dy/dx = 4/x.

To find the first derivative for each of the given functions, we'll use the power rule, constant rule, and chain rule as needed.

For the function\(y = 3x^2 + 5x + 10:\)

Taking the derivative term by term:

\(d/dx (3x^2) = 6x\)

d/dx (5x) = 5

d/dx (10) = 0

Therefore, the first derivative is:

dy/dx = 6x + 5

For the function y = 100200x + 7x:

Taking the derivative term by term:

d/dx (100200x) = 100200

d/dx (7x) = 7

Therefore, the first derivative is:

dy/dx = 100200 + 7 = 100207

For the function \(y = ln(9x^4):\)

Using the chain rule, the derivative of ln(u) is du/dx divided by u:

dy/dx = (1/u) \(\times\) du/dx

Let's differentiate the function using the chain rule:

\(u = 9x^4\)

\(du/dx = d/dx (9x^4) = 36x^3\)

Now, substitute the values back into the derivative formula:

\(dy/dx = (1/u) \times du/dx = (1/(9x^4)) \times (36x^3) = 36x^3 / (9x^4) = 4/x\)

Therefore, the first derivative is:

dy/dx = 4/x

To summarize:

For \(y = 3x^2 + 5x + 10,\) the first derivative is dy/dx = 6x + 5.

For y = 100200x + 7x, the first derivative is dy/dx = 100207.

For\(y = ln(9x^4),\) the first derivative is dy/dx = 4/x.

The sum of Peter, Richard, and John's ages is 191.

We know that the ratio of Peter's age to Richard's age is = 5/8 --(i)

The ratio of John's age to Peter's age is = 7/12 --(ii)

Similarly, the ratio of John's age to Richard's age is = (5*7)/(8*12)= 35/96 -(iii)

Using the value of (i),(ii),(iii), we get -

Age of Peter = (5*12)/(8*12) = 60/96

= 60 years of age

Age of John = (7*5)/(12*5) = 35/60

=35 years of age

From the value of (iii), since no one is over 100 years of age, the age of Richard= 96 years of age

Hence the sum of their ages is = 96+35+60

= 191

Therefore, we know that the sum of their ages is 191.

The marginal frequencies of chocolate and strawberry are 0.75 and 0.25 and chocolate is greater by 0.5

Marginal frequency is the ratio between either a column total or a row total and the total sample size.

For example, in a table of students classified by sex and area of study, the number of female students, regardless of area of study, would be one marginal frequency.

The marginal frequency of chocolate is calculated as;

The total frequency of chocolate = 30+45 = 75

The grand frequency = 75+25 = 100

marginal frequency of chocolate = 75/100

= 0.75

The marginal frequency of strawberry = 25/100

= 0.25

The difference in the marginal frequencies of chocolate and strawberry = 0.75 - 0.25 = 0.50

Therefore the marginal frequency of chocolate is greater than strawberry by 0.5

1. The probability of selecting exactly one tank with high-viscosity material is 0.

2. The probability of selecting at least one tank with high-viscosity material is 1.

3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is 0.25.

1. The probability of selecting exactly one tank with high-viscosity material is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 4, x = 1, and p = 24/24 = 1. Therefore, P(X = 1) = (4C1)1^1(1-1)^4-1 = 0.

2. The probability of selecting at least one tank with high-viscosity material is calculated by the complement rule, P(X > 0) = 1 - P(X = 0). In this case, P(X > 0) = 1 - (4C0)1^0(1-1)^4-0 = 1.

3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success.

Busby's most popular video grows by 10 percentage every month, then the busby likes will video have right now = 4400 times.

Given that,

Busby's most popular video grows by 10% every month

The total number of lights for the video and months from now will be 4000 times one.

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

We can write,

P = 4000

r = 10%

r = \(\frac{10}{100}\)

n = 1

t = 1

F = P * \((1+\frac{r}{n}) ^{nt}\)              ( Equation-1 )

We can substitute this values in equation-1,

F = 4000 \((1+\frac{\frac{10}{100} }{1} )^{1}\)

Evaluate the equation,

F = 4000 ( \((1+\frac{0.1}{1} )^{1}\)

F = 4000 ( 1 + 0.1 )

F = 4000 ( 1.1 )

F = 4400

Therefore,

Busby's most popular video grows by 10 percentage every month, then the busby likes will video have right now = 4400 times.

Answer:

The expression that represents the number of deer in the forest is

y(x) = 50*(1.013)^x

Step-by-step explanation:

Assuming that the number of deer is "y" and the number of months is "x", then after the first month the number of deer is:

y(1) = 50*(1+ 0.15/12) = 50*(1.0125) = 50.625

y(2) = y(1)*(1.0125) = y(0)*(1.0125)² =51.258

y(3) = y(2)*(1.0125) = y(0)*(1.0125)³ = 51.898

This keeps going as the time goes on, so we can model this growth with the equation:

y(x) = 50*(1 - 0.15/12)^(x)

y(x) = 50*(1.013)^x

The exponential growth function that represents the number y of deer in that forest after x months is 50 × \((1.013)^{x}\).

An exponential function is a nonlinear function that has the form of

y=\(ab^{x}\),wherea≠0,b>0. An exponential function with a > 0 and b > 1, like the one above, represents an exponential growth and the graph of an exponential growth function rises from left to right.

There are 50 deer in a particular forest.

The population is  increasing at a rate of 15% per year.

Assuming that the number of deer is 'y' and the number of month is 'x' then after the first month the number of deer is

y(x) = 50 × \(1+(\frac{0.15}{12} )\)

= 50 × 1.0125

= 50.625

y(2) = y(1) × (1.0125)

= y(0) × \((1.0125)^{2}\)

= 51.258

y(3) = y(2) × (1.0125)

= y(0) × \((1.0125)^{2}\)

= 51.898

y(x) = 50 × \((1-\frac{0.15}{12} )^{x}\)

= 50 × \((1.013)^{x}\)

Hence, the exponential growth function that represents the number y of deer in that forest after x months is 50 × \((1.013)^{x}\).

Rewrite in vertex form and use this form to find the vertex (h, k).

Answer:

\(\sf Vertex \left(\dfrac{3}{2}, \dfrac{-81}{4}\right)\)

Step-by-step explanation:

          y = x² - 3x - 18

       Add 18 to both sides.

           y + 18 = x² - 3x

     Divide the co-efficient of x by 2 and square the result and then add it to both sides.

      Co-efficient of x = 3. Divide 3 by 2and add (3/2)² to both sides

          \(\sf y + 18 + \left(\dfrac{3}{2}\right)^2= x^2 - 3x + \left(\dfrac{3}{2}\right)^2\\\\\\y + 18+\dfrac{9}{4}=x^2 - 3x + \dfrac{9}{4}\\\\\\\)

          \(\sf y + \dfrac{18*4}{1*4}+\dfrac{9}{4}=\left(x - \dfrac{3}{2}\right)^2\\\\\\y + \dfrac{72}{4}+\dfrac{9}{4}=\left(x - \dfrac{3}{2}\right)^2\\\\\\y + \dfrac{81}{4}=\left(x-\dfrac{3}{2}\right)^2\\\\ y = \left(x-\dfrac{3}{2}\right)^2 -\dfrac{81}{4}\\\\\)

Vertex form:  f(x) = (x - h)² + k
