The height of the redwood has been calculated as 372 meters.

In  order to get the height of this tree, I would have to make use of the similar triangles method. The proportion is set as

tree height / tree shadow = Eric's height / Eric's shadow

Eric's height is 6 feet, his shadow is 8 feet

The proportion is 6 / 8

= 3 / 4

To get the height of the tree we have to multiply the proportion by the distance with which Eric is away from the tree

= 3 / 4 * 496

= 372 feet

The redwood is 372 feet

So, on solving the provided question, we cans ay that new slope interest equation is y = 3x +c

In mathematics, the intersection point is the place on the y-axis where the slope of the line crosses. a place where the y-axis crosses on a line or curve. Y = mx+c, where m stands for the slope and c for the y-intercept, is used as the equation for the straight line to show this. The slope (m) of the line and its y-intercept (b) are emphasised in the equation's intercept form. When an equation has the intercept form (y=mx+b), the slope is m and the y-intercept is b. Some equations can also be rewritten such that they seem to be slope intercepts. If y=x is rewritten as y=1x+0, for instance, the slope and y-intercept are both changed to 1.

Therefore , the solution of the given problem of slope intercept comes out to be  y = 0.66x +12.65.

The gradient intercept method can be used once you are satisfied that Y = mx + b holds true. The direction form can be used to illustrate a hypothesis for a line by focusing on a single point directly and its slope. The slope is determined by the increase across the run and is first represented by the point form (x,y). The slope can be determined using slope intercept method, which is y = mx + b. (0, b). The direct form is a method for formulating a prediction equation for a line by making just one precise declaration about a vector slope.

Here,

Given : slope = 2/3

and coordinates = (0 , 12.65)

Thus ,

the equation of the given line by using formula of slope intercept:

=> y- y1  = m(x-x1 ) + c

=> y - 12.65 = 2/3*x

=> y = 0.66x +12.65

Therefore , the solution of the given problem of slope intercept comes out to be  y = 0.66x +12.65.

Answer: prime

Step-by-step explanation:

there is no greatest common factor (GCF) of the coefficients: 8 and -27. And the variables: c and d, are different so the polynomial is in its prime form.

The slope-intercept method is a way to graph a linear equation in the form of y = mx + b, where m is the slope and b is the y-intercept. This method allows you to find the slope and y-intercept of the line and use that information to graph the line.

An explanation graph is what?

A graph shows how two variables that are typically measured along one of a pair of axes at right angles relate to one another.

To graph a linear equation using the slope-intercept method, you can follow these steps:

Identify the y-intercept by looking for the constant term (b) in the equation. The y-intercept is the point where the line crosses the y-axis, so it will have an x-coordinate of 0.

Plot the y-intercept on the coordinate plane.

Identify the slope of the line by looking for the coefficient of the x-term (m) in the equation. The slope represents the steepness and direction of the line.

Using the slope and the y-intercept, pick a point on the x-axis and use the slope to find the corresponding point on the y-axis.

Plot the point found in step 4.

Plot the two spots and then draw a straight line through them.

Note that this method will work for any linear equation where y = mx + b, and can help you graph a line quickly.

Also note that there is another method to graph a linear equation, it's called the point-slope method which is starting from any point on the line and use the slope to locate the additional line points.

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 time to finish the milkshake by Lin and Diego be represented as A and B respectively

Now , the equation will be

The amount of milkshake with Lin = 12 ounce

The rate at which Lin finishes her milkshake = 1/3 milkshake per second

The time for Lin to finishes her milkshake A = amount of milkshake with Lin / rate at which Lin finishes her milkshake

Answer:

48 centimeters

Step-by-step explanation:

This deals with the midline theorem.

The midline is defined by a seg that is joined by the midpoints of 2 sides.

The midline is half of the base, so if it is 10, the base is 20 cm.

You see that 26 cm is 1/2 of the hypotenuse because it is bisected, sot he whole thing is 26(2) or 52.

Now you have to solve for x using the Pythagorean theorem.

20^2 (400) + x^2  = 52^2 (2704)

Subtracted 400 from both sides to get x^2 by itself.

x^2 = 2304

Take the square root of both sides to isolate x (take the principle root)

x= 48 centimeters.

Hope this helps!

The partial fraction decomposition in terms of x for the given equation is:

3x + 9 = (a(x-5) + b(x+1))

To solve for a and b, we need to multiply both sides by (x+1)(x-5). This will give us:

3x² + 4x - 45 = ax - 5a + ax + b

Now we can move all the terms with an x to one side and all the terms without an x to the other side. This will give us:

3x² + 4x - ax + b = 45 - 5a - b

We can rearrange this equation to get the following:

3x² - ax + (4 + b) = (45 - 5a - b)

Now we can use the quadratic formula to solve for a and b:

a = (4 + b) + √(4²- 4×3×(45 - 5a - b))/ (2×3)

b = (45 - 5a - (3x² - ax)) / (4 + b)
