12x=9y+27 in slope intercept form with work

Hi there!  

»»————-　★　————-««

I believe your answer is:  

slope - 3

y - intercept - 40

Here’s why:  

⸻⸻⸻⸻

\(y = 3x + 40\\\rule{150}{0.5}\\y \text{ - Total service fee.}\\\\x \text{ - Number of miles the car is towed.}\\\rule{150}{0.5}\\\text{The given equation is in slope-intercept form.}\\y = mx + b\\\\\rightarrow m \text{ - slope}\\\rightarrow b \text{ - y-intercept}\\\rule{150}{0.5}\\\text{3 takes m's spot so it is the slope.}\)

\(\text{This means that the company will charge 3 dollars for every mile the car is towed.}\\\rule{150}{0.5}\\\text{40 takes b's place to it is the y-intercept. This means that 40 would be the base fee.}\)

Hope this helps you. I apologize if it’s incorrect.  

Answer:

To compute the average speed, multiply the total distance travelled by the whole time spent. There's a formula for speed, time and distance

Travel distance aboard the pterodactyl = 10 mph x 3 hours = 30 miles

Distance travelled on the spinosaurus = 2 miles x 1 hour = 2 miles

30 miles + 2 miles = 32 miles total distance travelled

Total time required = 3 hours + 1 hour = 4 hours

Average speed = total distance travelled divided by the total time taken = 32 miles divided by 4 hours = 8 mph

As a result, our average speed is 8 mph.

Yes, the two triangles are similar because they have equal angles.

Two objects are similar if they have the same shape, or if one has the same shape as the mirror image of the other. More precisely, one can be obtained from the other by uniformly scaling.

Two triangles are similar if their corresponding angles are equal and their corresponding sides are within the same ratio (or proportion). Similar triangles will have the same shape, but not necessarily the same size.

The missing side of the first triangle is 180-(111+24)

= 180-135

= 45°

The Missing angle of the second triangle is 180-(45+24) = 180-79

= 111°

This means that the corresponding angle of the triangle are equal and hence they are similar.

Yes, the triangles are similar.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Therefore, similar triangle have the corresponding angles equal to each other and the corresponding sides as a ratio of each other.

Hence, If two triangles have two of their angles equal, the triangles are similar by AA(angles angles).

Hence, let's check if two angles are equal in the triangles as follows:

180 - 111 - 24 = 45 degrees.

Therefore, the triangles are similar.

There are various ways to represent the negation of a statement, or proposition p. One possible method is to use the symbol ~. Therefore, the negation of proposition p would be represented as ~p.

Similarly, if the proposition p is defined as "it is not snowing," then the negation of p, or not-p, would be represented as ~p or "it is snowing." This is because the negation of "it is not snowing" is "it is snowing."Thus, the equivalent proposition of not-p is "it is snowing." In summary, the negation of any statement p is a proposition that is the opposite of p. The negation of "it is not snowing" would be "it is snowing."Long explanation:For any statement p, there are different ways to express its negation or opposite. One way is to use the logical negation symbol, which is ~.

If p is the proposition "it is not snowing," then the negation of p or not-p would be represented as ~p or "it is snowing." This is because the negation of a negative statement is a positive statement. For instance, if we negate the statement "I am not happy," the result would be "I am happy." Likewise, if we negate the statement "it is not snowing," we would obtain "it is snowing."Therefore, the equivalent proposition to not-p is "it is snowing." This is because not-p is the negation of p, which means that it is the opposite of p. Since p is "it is not snowing," then not-p would be "it is snowing."

The notation used for a vector pointing into the point is X.

A quantity with a magnitude and direction is called a vector. A vector quantity will be identified in these annotations by a bold letter (such as the electric field vector E). Vectors appear graphically as straight arrows. The magnitude of the vector is commonly represented by the length of the arrow, and both the arrow and the vector point in the same general direction.

Arrows are drawn on the page to represent vectors in the page's plane. Typically, circles with an X engraved on them are used to represent vectors that enter the screen's plane. A vector that deviates from the screen's plane is often represented by circles with dots in the center.

The volume of the solid generated by revolving the region in the first quadrant bounded by the coordinate axes is V = π∫ln 8eˣdx,

The volume of a solid generated by revolving a region about a line is calculated by using the method of slices.

In this case, we have a region in the first quadrant bounded by the coordinate axes, the curve y = eˣ and the line x = ln 8, which is being revolved about the line x = ln 8.

To find the volume of this solid, we need to take slices perpendicular to the line of rotation and calculate the area of each slice.

The volume can then be calculated by multiplying the area of each slice by its corresponding distance from the line of rotation and summing up the results.

The volume of this solid is calculated by the equation

=> V = π∫ln 8eˣdx,

where V is the volume of the solid, x is the distance from the line of rotation, and π is the constant pi

To estimate the variance of the error term, σ², and Var(B₁), we can use the formulas provided in equation (2.61) from the CLM Assumptions.

In equation (2.61) of the CLM Assumptions, the variance of the error term, σ², is estimated as:

σ² = (SSE / (n - k - 1))

where SSE is the sum of squared errors, n is the sample size, and k is the number of independent variables in the model (excluding the constant term). Since the given equation is a simple linear regression model with one independent variable (x₁), k would be 1.

To calculate SSE, we need to compute the sum of squared differences between the actual y values and the predicted values based on the estimated regression line. However, we do not have the predicted values or the estimated coefficients (β₀ and β₁) provided in the question. Without these values, we cannot calculate the SSE or estimate σ².

Similarly, to estimate the variance of B₁ (Var(B₁)), we need the estimated standard error of B₁. The standard error of B₁ can be calculated using the formula:

SE(B₁) = sqrt(σ² / (n * Var(x₁)))

However, without the estimated coefficients or the predicted values, we cannot calculate the standard error of B₁ or estimate Var(B₁).

Without the necessary values (estimated coefficients or predicted values), we cannot calculate the variance of the error term (σ²) or the variance of B₁ (Var(B₁)). The provided information is insufficient to perform these calculations.

Explanation:

Your teacher shows that minor arc BD is 129 degrees. Recall that any minor arc is always less than 180 degrees.

Let's say that we had point A at the center of the circle. This would mean angle DAB is 129 degrees. This central angle subtends or cuts off minor arc BD.

Now focus entirely on quadrilateral DABC. The goal is to find the unknown angle C. The angle A was found earlier at 129 degrees. The angles B and D are 90 degrees each since tangents are perpendicular to the radius at the point of tangency.

We have this so far

Adding all four angles of any quadrilateral will always get us 360 degrees. It's similar to how adding the angles of a triangle gets us 180 degrees. In fact, any quadrilateral can be cut into two triangles (aka the process of triangulation). So adding two triangles gets us 180+180 = 360 more or less.

--------------

Anyways, the four angles A,B,C,D must add to 360. So,

A+B+C+D = 360

129+90+C+90 = 360

C+309 = 360

C = 360-309

C = 51

--------------

As a shortcut, note how B+D = 90+90 = 180

Also note that A+C = 360-(B+D) which becomes A+C = 180

So, C = 180-A = 180-129 = 51

The surface area of the larger sphere is 64π cm². therefore option A. 64π cm² is correct.

To find the surface area of the larger sphere, given the volumes of two spheres and the surface area of the smaller sphere, follow these steps:

1. Determine the ratio of the volumes of the spheres:

Volume ratio = Volume of larger sphere / Volume of smaller sphere

                     = (64π cm³) / (8π cm³)

                     = 8

2. Find the cube root of the volume ratio to get the ratio of their radii:

Radii ratio = cube root of volume ratio = cube root of 8 = 2

3. Since the surface area of a sphere is proportional to the square of its radius, find the ratio of the surface areas by

squaring the radii ratio:

Surface area ratio = (Radii ratio)² = (2)² = 4

4. Finally, multiply the surface area of the smaller sphere by the surface area ratio to get the surface area of the larger

sphere:

Surface area of larger sphere = Surface area of smaller sphere × Surface area ratio

                                                 = 16π cm² × 4

                                                = 64π cm²

So, the surface area of the larger sphere is 64π cm² (Option A).
