Answer:

F.

Explanation:

The number of quarts of cream Type A is x.

Type A cream has 18% butterfat, so the amount butterfat will be 0.18x

For type B, we know that the total amount of cream will be 90, so if cream type A is x, cream type B is 90 - x.

Type B crem has 24% butterfat, so teh amount in the mixture will be 0.24(90-x)

Then, the mixture will be 90 quarts of crean that is 22% butterfat, so the amount in the mixture will be 0.22(90)

Therefore, the table that represent this data is table F.

Answer:

y = -15x - 3.04

Step-by-step explanation:

1) First place down what you are given.

Y = a(x - p) (x - q)

2) Then Substitute.

a = -16

p = -0.12

q = 1.12

y = (-16)(x - (-0.12))(x - (1.12)

3) Do order of operations (PEMDAS)

y = (-16)(x + 0.12)(x - 1.12)

Now distribute

y = − 16 x  −  1.92 + (x - 1.12)

y = -16x - 1.92 + x - 1.12

y = -16x + x - 1.92 - 1.12

y = -15x - 3.04

4)

You answer is:

y = -15x - 3.04

Answer:

Center ( 4 , -2) and r = 6

Step-by-step explanation:

x² - 8x + y² + 4y - 16 = 0

x² - 8x  + y² + 4 y = 16

x²- 2*4x + y² + 2 *2y = 16

(x² - 2*4x + 16 ) - 16 + (y² + 2*2y + 4) -4 = 16

(x - 4)² + (y + 2)² = 16 + 16 + 4

(x - 4)² + (y -[-2])² = 36

(x- 4)² + ( y - [-2] )² = 6²

Compare with (x - h)²+ (y - k)² = r²

The volume flow Q through a small triangular section pore can be related to viscosity, pressure drop per unit length, and pore size through the Buckingham Pi theorem.

Let's first identify the fundamental dimensions involved in this problem:

Length (L)

Mass (M)

Time (T)

Using these fundamental dimensions, we can form three dimensionless pi groups that express the relationship between the variables:

Reynolds number: Re = (ρVL)/µ, where ρ is the density of the fluid, V is the characteristic velocity (which is proportional to pressure drop per unit length), µ is the viscosity of the fluid, and b and L are characteristic length scales.

Aspect ratio: Γ = L/b

Shape factor: Ψ = (Qb²)/(µVL)

The volume flow Q can therefore be written in terms of the other variables as:

Q = (ΨµVL)/b²

To answer the second part of the question, if the pore size b is doubled, the volume flow Q will increase by a factor of 4, assuming all other variables remain constant. This is because the shape factor Ψ is proportional to b², so doubling b will lead to a four-fold increase in Ψ and thus in Q.

Step-by-step explanation:

to find the x- intercept, where the line crosses the x- axis, let y = 0 in the equation and solve for x.

- 4x - 5(0) = - 80

- 4x - 0 = - 80

- 4x = - 80 ( divide both sides by - 4 )

x = 20

then x- intercept is (20, 0 )

to find the y- intercept, where the line crosses the y- axis, let x = 0 in the equation and solve for y.

- 4(0) - 5y = - 80

0 - 5y = - 80

- 5y = - 80 ( divide both sides by - 5 )

y = 16

then y- intercept is (0, 16 )

When we roll three fair coins, there are two possible outcomes for each coin - either it lands heads up or tails up. There are 8 elementary events in the sample space of the experiment of rolling three fair coins.

The sample space of this experiment consists of all possible combinations of three outcomes, which can be calculated by multiplying the number of outcomes for each coin: 2 x 2 x 2 = 8.
Each of these combinations is called an elementary event, which means that there are 8 elementary events in the sample space of the experiment of rolling three fair coins. We can list them as follows:
1. HHH (all three coins land heads up)
2. HHT (two coins land heads up, one lands tails up)
3. HTH (two coins land heads up, one lands tails up)
4. THH (two coins land heads up, one lands tails up)
5. HTT (one coin lands heads up, two land tails up)
6. THT (one coin lands heads up, two land tails up)

The equation of the line parallel to the line shown in the graph passing through the point (-2, 3) is y = (2/3)x + (13/3) and the equation of the line perpendicular to the line shown in the graph passing through the point (-2, 3) is y = (-3/2)x.

What is slope?

The slope of a line passing through two points \((x_1, y_1) \: and \: (x_2, y_2)\) is given by slope = \(\frac{(y_2 - y_1)}{(x_2 - x_1)}\)

Given line passes through (0,-6) and (9,0)

To find the equation of a line parallel to a given line, we need to use the fact that parallel lines have the same slope.

The slope of the line passing through (0,-6) and (9,0) can be found using the slope formula

slope = (change in y) / (change in x)

= (0 - (-6)) / (9 - 0)

= 6 / 9

= 2/3

Therefore, any line parallel to this line will also have a slope of 2/3.

We can now use the point-slope form of a line to find the equation of the line passing through (-2,3) with a slope of 2/3:

y - y1 = m(x - x1) (point-slope form)

where m is the slope, and (x1,y1) is a point on the line.

Substituting the values, we get:

y - 3 = (2/3)(x - (-2))

y - 3 = (2/3)(x + 2)

y - 3 = (2/3)x + (4/3)

y = (2/3)x + (4/3) + 3

y = (2/3)x + (13/3)

Therefore, the equation of the line parallel to the line passing through (0,-6) and (9,0) shown in the graph passing through the point (-2, 3) is y = (2/3)x + (13/3).

Using the points (0,-6) and (9,0), we can find the slope of the original line:

slope = (0 - (-6)) / (9 - 0) = 6/9 = 2/3

The slope of any line perpendicular to this line will be the negative reciprocal of this slope. So, the slope of the perpendicular line will be:

perpendicular slope = -1 / (2/3) = -3/2

Now we have the slope of the perpendicular line, and we also have a point it passes through: (-2, 3). We can use the point-slope form of a line to write the equation of the perpendicular line: y - y1 = m(x - x1)

where m is the slope of the line, and (x1, y1) is the point it passes through. Plugging in the values we have, we get:

y - 3 = (-3/2)(x - (-2))

Simplifying:

y - 3 = (-3/2)x - 3

y = (-3/2)x + 0

So the equation of the line perpendicular to the line passing through (0,-6) and (9,0), and passing through (-2, 3), is y = (-3/2)x.

There are no values of t on the interval [0,3] where the value of the derivative is equal to the average rate of change for the function \(v(t)=4t^2-6t+2.\)

The derivative of the function v(t) can be found by taking the derivative of each term separately. Applying the power rule, we get v'(t) = 8t - 6. To determine the average rate of change, we need to calculate the difference in the function's values at the endpoints of the interval and divide it by the difference in the corresponding values of t.

In this case, the average rate of change is (v(3) - v(0))/(3 - 0). Simplifying this expression gives (35 - 2)/3 = 33/3 = 11.

Now, we set the derivative v'(t) equal to the average rate of change, which gives us the equation 8t - 6 = 11. Solving this equation, we find t = 17/8. Since the interval is [0,3], we need to check if the obtained value of t falls within this interval.

In this case, t = 17/8 is greater than 3, so it does not satisfy the conditions. Therefore, there are no values of t on the closed interval [0,3] where the value of the derivative is equal to the average rate of change for the given function.
