Answer: An angle that measures 180° would be a straight angle.

Step-by-step explanation:

This question is asking to identify an angle that measures 180°. To find if this angle is acute, obtuse, right, or straight is to measure them each.

Acute Angle - Acute angles are angles that measures less than 90° degrees

Obtuse Angle - Obtuse angles are any angles that greater than 90° with the exception of an 180° angle

Right Angle - Right angles are angles that are exactly equal to 90°

Straight Angle -  Straight angles are defined angles that are exactly 180 ° degrees.

Since a straight angle is 180° degrees. Therefore, this angle would be defined as a straight angle. Hope this helps!

The critical points are (2,1) and (0,0). Given, z = 3x² - xy + 2y² - 4x - 7y + 12.1. Find the critical points at which the function may be optimized.

To find the critical points, we need to solve the following system of equations: ∂z/∂x = 0, ∂z/∂y = 0∂z/∂x = 6x - y - 4 = 0∂z/∂y = -x + 4y - 7 = 0By solving these equations, we get two critical points: (2,1) and (0,0).2. Determine whether at the computed points, the function takes on its maximum or minimum value.

To determine whether each critical point is a maximum, minimum, or saddle point, we need to compute the second partial derivatives of z: ∂²z/∂x² = 6, ∂²z/∂y² = 4, ∂²z/∂x∂y = -1At the point (2,1), the second partial derivatives satisfy the condition (∂²z/∂x²)(∂²z/∂y²) - (∂²z/∂x∂y)² = (6)(4) - (-1)² = 25 > 0 and ∂²z/∂x² > 0, so z has a minimum value at this point.At the point (0,0), the second partial derivatives satisfy the condition (∂²z/∂x²)(∂²z/∂y²) - (∂²z/∂x∂y)² = (6)(4) - (-1)² = 25 > 0 and ∂²z/∂x² > 0, so z has a minimum value at this point.Therefore, the function z = 3x² - xy + 2y² - 4x - 7y + 12 is optimized at (2,1), where the minimum value is z = 3(2)² - (2)(1) + 2(1)² - 4(2) - 7(1) + 12 = -10.

The value of a dependent variable is dependent on the value of an independent variable. The correct option is C.

Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on other.

The complete question is:

A telephone company charges a $0.25 connection fee, then $0.10 per minute for long distance calls. Which statement is true regarding this situation?

A. The rate of change is $0.25 and minutes are the independent variable.

B. The rate of change is $0.25 and minutes are the dependent variable.

C. The rate of change is $0.10 per minute and minutes are the independent variable

D. The rate of change is $0.10 per minute and minute are the dependent variable.

The cost of making a call is the sum of the cost of connection fee which is one time fee and cost $0.25, and the cost charged for a minute which depends on the number of minute for which the call is been established. Therefore, the total cost can be written for a x minute call is,

Total Cost = $0.25 + $0.10(x)

Since the total cost is dependent on x, therefore, x which is the minute is the independent variable. The rate of change is $0.10 per minute and minutes are the independent variable.

Hence, the correct option is C.

Before the formation of fog, the dew point remained almost constant, and after the fog formed, the dew point began to decrease because of the continuous process of condensation.

Fog is a type of cloud that is formed by the condensation of water vapor present in the air on small particles like dust, smoke or salt, etc. which forms the nuclei for condensation.

During the winter night, when the temperature is cool and the air cools down, the dew point temperature also drops down.

The dew point temperature is the temperature below which the air starts to cool down, and the water vapors present in the air start to condense.

When the air temperature becomes equal to the dew point temperature, it starts to condense and form fog.

Before the formation of fog, the dew point remained almost constant because the air temperature was not as low as it was required to cool down the water vapors present in the air to the dew point temperature.

The dew point temperature remains constant until the air temperature drops below the dew point temperature.

After the fog formed, the dew point began to decrease because the process of condensation of water vapor continues to occur and the water vapors present in the air continue to convert into water droplets.

As the water droplets are removed from the air, it causes the humidity of the air to decrease, which in turn causes the dew point temperature to decrease.

Hence, on a winter night, the air temperature cooled to the dew point and fog was formed.

Before the formation of fog, the dew point remained almost constant, and after the fog formed, the dew point began to decrease because of the continuous process of condensation.

Answer:

y=12x-45

Step-by-step explanation:

First we want to get y=12(x+4) into Slope intercept form which is y=mx+b and we do that by multiplying 12 by x so we get 12x and multiplying 12 by 4 so we get 48.

Now we have:

y=12x+48

where the slope is 12.

Parallel lines have the same slope. so the line that goes through (4,3) will have the same slope.

Now that we have a slope and a point we want to write an equation in point-slope form: y-y1=m(x-x1)

Step 1 for this: y-3=12(x-4)

Step 2: we will distribute and solve for y so our answer is in slope intercept form.  

Step 3: we now have the equation y-3=12x-48 after distributing now we add 3 to -3 so it cancels out and we add 3 to -48 and we get -45

Our answer is y=12x-45

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount of pie Kevin and Su Yung ate be = A

Now , the equation will be

The amount of pie Kevin ate = 2/5 of the total pie

And ,

The amount of pie Su Yung ate = 3/10 of the total pie

Answer:

y=-x+3.

Step-by-step explanation:

The graph goes down one and right one before making another point. This means that the slope is -1/1. Simplify and you get -1. So far we have y=-1x. -1x is the same as -1. Now we have y=-x. The graph intersects the y-axis at the point (0,3). This makes our y-intercept 3. Our final equation is y=-x+3.

1 foot is equal to 12 inches. So one feet is equal to 12 inches. The conversion factor between feet and inches is 1 ft = 12 in.

Inches (in) and feet (ft) are both units of measurement for length, but they are not directly interchangeable. To convert a measurement of length from feet to inches, you will need to use a conversion factor.

To convert a measurement of length from feet to inches, you will multiply the number of feet by the conversion factor of 12.

For example,

if you have a measurement of 2 feet, you would multiply 2 x 12 to get 24 inches. So, 2 ft = 24 in.

It's important to note that when measuring length, it's important to use the same system of measurement as the requirement, as using the wrong measurements can greatly affect the outcome of the calculation. It's always good to know the conversion factors to make your calculations easier.
