Answer:
q = 4p - 32
Step-by-step explanation:
P = 1/4q + 8
Making q the subject
P - 8 = 1/4q
Divide both sides by 1/4
q = (p - 8) ÷ 1/4
= (P - 8) × 4/1
= 4p - 32

Differentiate the function. f(x) = sin(6 In(x)) Step 1 Recall the Chain Rule in terms of the functions h(x) and g(x), which states that if g is differentiable at x and h is differentiable at g(x), then the composite function F= h og defined by F(x) = (g()) is differentiable at x and F'is given by the following. F'(x) = h'(g(x)).g'(x) We are given the function f(x) = sin(6 In(x)) To write this is the form F(x) = (g(x)) we can let g(x) = 6 In(x) and h(x) =____
The required differentiation of the function f(x) = sin(6 In(x)) is f'(x) = 6 cos(6 ln(x))/x.
Given the function f(x) = sin(6 In(x)).
To differentiate the function f(x), we need to use the Chain Rule in terms of the functions h(x) and g(x), which states that
if g is differentiable at x and h is differentiable at g(x), then the composite function F= h og defined by F(x) = (g(x)) is
differentiable at x and F' is given by the following.
'(x) = h'(g(x)).g'(x)We can let g(x) = 6 In(x) and h(x) = sin(x).
Now, we can rewrite f(x) as f(x) = h(g(x)) = sin(6 In(x)).
To differentiate this function, we will differentiate h(g(x)) using the Chain Rule.
f'(x) = h'(g(x)) × g'(x)
Substituting the values of h(x) and g(x), we havef'(x) = cos(6 ln(x)) × (6/x) = 6 cos(6 ln(x))/x
Thus, the required differentiation of the function f(x) = sin(6 In(x)) is f'(x) = 6 cos(6 ln(x))/x.

A. It is the graph of f(x) where the slope is increased by 11.
It is the graph of f(x) translated 11 units to the left.
It is the graph of f(x) translated 11 units up.
It is the graph of f(x) translated 11 units to the right.
B.
C.
OD.
The correct answer is C. It is the graph of f(x) translated 11 units to the left.
The correct answer is:
C. It is the graph of f(x) translated 11 units to the left.
When we have a function of the form g(x) = f(x - a), it represents a horizontal translation of the graph of f(x) by 'a' units to the right if 'a' is positive and to the left if 'a' is negative.
In this case, g(x) = f(x - 11), which means that the graph of f(x) is being translated 11 units to the right. However, the answer options do not include this specific transformation. The closest option is option C, which states that the graph of g(x) is translated 11 units to the left.
The graph of f(x) = x is a straight line passing through the origin with a slope of 1. If we apply the transformation g(x) = f(x - 11), it means that we are shifting the graph of f(x) 11 units to the right. This results in a new function g(x) that has the same shape and slope as f(x), but is shifted to the right by 11 units.
Therefore, the correct answer is C. It is the graph of f(x) translated 11 units to the left.

Answer: 0 is the answer
if my answer is correct mark as brainliest
Rewrite the fractions as improper fractions:
2 1/4 = 9/4
1 4/5 = 9/5
Rewrite the fractions to have a common denominator:
9/4 = 45/20
9/5 = 36/20
The sum is adding the two together:
45/20 + 36/20 = 81/20
Rewrite as a mixed number:
81/20 = 4 1/20
Product is multiplication:
For multiplying you can use different denominators so you can use the first improper fractions:
9/4 x 9/5 = (9x9)/(4x5) 81/20
Rewrite as a mixed number: 4 1/20
Now subtract to find the difference: 4 1/20 - 4 1/20 = 0
The difference = 0
lily has a garden with a ratio of 6:11 there are 75 more pink flowers than blue flowers. How many pink flowers does she have?
There are 165 pink flowers in the garden.
What is a ratio?Ratio and Proportion are explained majorly based on fractions. When a fraction is represented in the form of a:b, then it is a ratio whereas a proportion states that two ratios are equal. Here, a and b are any two integers. The ratio and proportion are the two important concepts, and it is the foundation to understand the various concepts in mathematics as well as in science.
Let the number of blue flowers be x, so that number of pink flowers be x + 75
The total flowers will be = 2x + 75
Total share , 6 + 11 = 17
blue's share = 6/17 x (2x + 75)
so that,
6/17 x (2x+75) = x
by cross multiplying
6(2x+75) = 17x
Multiply out
12x + 450 = 17x
collect like terms
17x - 12x = 450
5x = 450
x = 450/5
x = 90
Total pink flowers , x + 75 = 90 + 75

Suppose that the population size P(t) of the species can be modeled by the following function, where time t is measured in years
Answer:
378 individuals
601 individuals
Explanation:
We know that the population after t years is described by:
\(P(t)=\frac{790}{1+7e^{-0.31t}}\)So, to know the population after 6 years, we need to replace t by 6 and calculate P(t). Then:
\(\begin{gathered} P(6)=\frac{790}{1+7e^{-0.31(6)}} \\ P(6)=\frac{790}{1+7e^{-1.86}} \\ P(6)=\frac{790}{1+7(0.156)} \\ P(6)=\frac{790}{1+1.089} \\ P(6)=\frac{790}{2.089} \\ P(6)=378 \end{gathered}\)In the same way, we can calculate the population after 10 years replacing t by 10. So:
\(\begin{gathered} P(10)=\frac{790}{1+7e^{-0.31(10)}} \\ P(10)=\frac{790}{1+7e^{-3.1}} \\ P(10)=\frac{790}{1+7(0.045)} \\ P(10)=\frac{790}{1+0.3153} \\ P(10)=\frac{790}{1.3153} \\ P(10)=601 \end{gathered}\)Therefore, the answers are:
378 individuals

A rectangle has a length of 32 yards less than 10 times its width. If the area of the rectangle is 384 square yards, find the length of the rectangle.
The length of the rectangle is 48 yards.
Let's denote the width of the rectangle as "w" yards.
According to the information given, the length of the rectangle is 32 yards less than 10 times its width. So, the length can be represented as: 10w - 32 yards.
The formula for the area of a rectangle is length times width: Area = length × width.
Given that the area of the rectangle is 384 square yards, we can set up an equation:
Area = length × width
384 = (10w - 32) × w
Now, let's solve for the width (w):
384 = 10w² - 32w
0 = 10w² - 32w - 384
Dividing the equation by 2 to simplify:
0 = 5w² - 16w - 192
Now we have a quadratic equation. We can either factor it or use the quadratic formula to solve for "w." Let's use the quadratic formula:
w = (-b ± √(b² - 4ac)) / 2a
For our equation, a = 5, b = -16, and c = -192. Plugging these values into the formula:
w = (16 ± √((-16)² - 4 × 5 × (-192))) / (2 × 5)
w = (16 ± √(256 + 3840)) / 10
w = (16 ± √4096) / 10
w = (16 ± 64) / 10
This gives us two possible solutions for the width:
w = (16 + 64) / 10 = 8 yards
w = (16 - 64) / 10 = -4.8 yards
Since width can't be negative, we'll ignore the second solution.
So, the width of the rectangle is 8 yards. Now, let's find the length using the earlier expression:
Length = 10w - 32
Length = 10 × 8 - 32
Length = 80 - 32
Length = 48 yards
Therefore, the length of the rectangle is 48 yards.

What is the intermediate step in the form (x+a)^2=b as a result of completing the square for the following equation?
-5x^2 - 50x = -250
The required intermediate step is (x-5)² = 25 for the equation -5x² - 50x = -250.
Completing the square is a method used to rewrite the equation in the form (x+a)²=b. The intermediate step involves adding and subtracting the square of half of the coefficient of x in the equation.
To complete the square for the equation -5x² - 50x = -250:
First, we'll add and subtract (1/2 * 50)² = 625/4 on both sides of the equation:
-5x² - 50x + 625/4 = -250 + 625/4
Next, we'll factor out the x term on the left side of the equation:
-5x² - 50x + 625/4 = -250 + 625/4
-5(x² - 10x) + 625/4 = -250 + 625/4
-5(x² - 10x + 25) + 625/4 = -250 + 625/4
-5(x - 5)² + 625/4 = -250 + 625/4
The intermediate step is in the form of (x-5)² = (625/20 + 250)/5
So, the intermediate step is (x-5)² = 25

Answer:
The function that passes through (0, 0) is \(f(x) = \frac{1}{6}\cdot e^{2\cdot x^{3}} - \frac{1}{6}\).
Step-by-step explanation:
Firstly, we integrate the function by algebraic substitution:
\(\int {x^{2}\cdot e^{2\cdot x^{3}}} \, dx\) (1)
If \(u = 2\cdot x^{3}\) and \(du = 6\cdot x^{2} dx\), then:
\(\int {e^{2\cdot x^{3}}\cdot x^{2}} \, dx\)
\(\frac{1}{6}\int {e^{u}} \, du\)
\(f(u) = \frac{1}{6}\cdot e^{u} + C\)
\(f(x) = \frac{1}{6}\cdot e^{2\cdot x^{3}} + C\)
Where \(C\) is the integration constant.
If \(x = 0\) and \(f(0) = 0\), then the integration constant is:
\(\frac{1}{6}\cdot e^{2\cdot 0^{3}} + C= 0\)
\(C = -\frac{1}{6}\)
Hence, the function that passes through (0, 0) is \(f(x) = \frac{1}{6}\cdot e^{2\cdot x^{3}} - \frac{1}{6}\).
