The cross product or the curl of F, G, and H are zero so they are scaler fields.

The cosine of the angle between the vectors and their magnitude are combined to form the dot product.

The dot product is represented by A.B = ABCos θ.

The sine of the angle between the vectors and their magnitude are combined to form the cross-product.

The cross product is represented by A×B = ABSin θ.

Given, F × (G × H) = (F . H)G - H(F .G).

∴ F × (G × H) = (FHcosФG) - H(FGcosФ).

F × (G × H) = FGHcosФ - FGHcosФ.

F × (G × H) = 0.

We know that cross-product is the curl of a vector field and if the curl is zero it is a scalar field.

Elena can make 20/3 cups of purple paint

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

WE are given that Elena makes her favorite shade of purple paint by mixing 3 cups of blue paint, 1 1/2 cups of red paint, and 1/2 cup of white paint.

Since Elena has 2/3 cup of white paint. then;

1 1/2 cups of red paint (1 1/2=1.5)

1/2 cup of white paint (1/2=0.5)

Then the ratio is 3:1.5:0.5

Means every 0.5 cups of white paint Elena makes 5 cups of purple paint (3+1.5+0.5)

Let x the number of cups of purple paint

5/ 0.5 = x / (2/5)

x = 20/3 cups of purple paint

What is log function?

The logarithm (log) function is a mathematical function used to determine the logarithm of a number. The logarithm of a number is the exponent to which a particular base must be raised in order to produce that number. For example, the logarithm of 8 with base 2 is equal to 3 because 2 to the third power is 8. In mathematics, the logarithm of a number can be expressed as logbX, where b is the base and X is the number.

Step-by-step explanation:

We can write -

0.006 = 6 x 10^-3

10ⁿ =  6 x 10^-3

[tex]10^{n+3}[/tex]  = 6

log([tex]10^{n+3}[/tex]) = log(6)

(n + 3) log 10 = log (6)

n +3 = log(6)/log(10)

n + 3 = 0.78

n = -3 + 0.78

n = -3 (approx.)

The patient should receive 909 mL of the TPN solution per day.

To determine the amount of the TPN solution the patient should receive per day, we need to use the following formula:

amount of TPN solution = (grams of protein needed / percentage of amino acids in TPN solution) × 100

In this case, we are given that the TPN solution contains 8.25% amino acids and that the patient needs 75 grams of protein per day. Substituting these values into the formula, we get:

amount of TPN solution = (75 / 8.25) × 100

amount of TPN solution = 9.09 × 100

amount of TPN solution = 909 mL

Therefore, the patient should receive 909 mL of the TPN solution per day.

Using ratios and proportions, he can make 15 batch of muffins from 2 bags of cornmeal

Ratio is used for comparing two quantities of the same kind. The ratio formula for two numbers, a and b is expressed as a : b or a/b. When two or more ratios are equal, they are said to be in proportion. The concept of ratio and proportion is based on fractions.

Proportion refers to the equality of two ratios. Two equivalent ratios are always in proportion. Proportions are denoted by the symbol (: :) and they help us to solve for unknown quantities. In other words, proportion is an equation or statement that is used to depict that the two ratios or fractions are equivalent.

In this problem, we know that he has 2 bags of cornmeal

1 bag of cornmeal = 25 serving

2 bags = x

x = 2 * 25 = 50 servings

When making muffins, he needs 2.5 cups in a batch

But 3/4 cup = 1 serving

x cups = 50 serving

x = 50 * 3/4

x = 37.5 cups

1 batch = 2.5 cups

x batch = 37.5 cups

x = 37.5 / 2.5

Step-by-step explanation:

Tom wants to know if a 70 cm chest will fit in the space left by a 67 in bed in a room 86 in wide.

The space available is 86 in -67 in = 19 in.

An approximate conversion between cm and inches is that 10 cm corresponds to about 4 in. Then 70 cm will correspond to 7×4 = 28 inches, much too wide for a 19-inch space.

The chest will not fit next to the bed.

Answer:

  A, C

Step-by-step explanation:

You want to know which answer choices are angles that are coterminal with 3π/2.

Angles are coterminal when their terminal rays lie in the same position. In general, any angle will be coterminal with angles that are an integer multiple of 2π added to the original.

That is, an angle is coterminal with all angles that have the same value modulo 2π.

For the given angle and each of the answer choices, the attachment calculates the coefficient of π modulo 2. The ones that match the given angle are ...

 A. 11π/2 mod 2π = 3π/2

  C. -7π/-2 mod 2π = 3π/2

__

Additional comment

Both -π/-2 and π/2 match the angle π/2, which is not the same as 3π/2.

Of course, the minus signs in numerator and denominator cancel, so -7π/-2 is the same as 7π/2.

Step-by-step explanation:

Answer:x = -9, y = -3

Step-by-step explanation:

y=1/3x+4 is perpendicular to y=-3x-4,

y=2/5x-7 is perpendicular to y=-5/2x+7,

y=-5/2x+8 is perpendicular to y=2/5x+6,

y=-2x+6 is perpendicular to y=1/2x+3 and  

y=7/5x-9 is perpendicular to y=-5/7x-11.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We know that the product of slopes of perpendicular lines is -1.

mM=-1

m is slope of one line and M is the slope of perpendicular line.

M=-1/m

y=1/3x+4

The perpendicular line is y=-3x-4

y=2/5x-7

The perpendicular line is y=-5/2x+7

y=-5/2x+8

The perpendicular line is y=2/5x+6

y=-2x+6

The perpendicular line is y=1/2x+3

y=7/5x-9

The perpendicular line is y=-5/7x-11.

Hence, the lines with corresponding perpendicular lines are

y=1/3x+4---> y=-3x-4

y=2/5x-7-----> y=-5/2x+7

y=-5/2x+8----->y=2/5x+6
