Graph y=8.5xy=8.5xy, equals, 8, point, 5, x.

Morgarella [4.7K]

Answer:

A, B, E

Step-by-step explanation:

<u>Given equation</u>

y = 8.5x

<u>Answer choices</u>

A. The equation represents a proportional relationship.

TRUE, it is in the form of y = kx

B. The unit rate of change of y with respect to x is 8.5

TRUE, y = mx + b, the slope m = 8.5 is the rate of change

C. The slope of the line is 2/17

False, the slope is 8.5

D. A change of 17 units in x results in a change of 2 units in y.

False, a change of x = 17 results in 17*8.5 = 144.5 units in y

E. A change of 4 units in x results in a change of 34 units in y.

TRUE, because 4*8.5 = 34

50 points! Tell whether the orthocenter is inside, on, or outside the triangle. Then find the coordinates of the orthocenter.

Nady [450]

Answer:

(1,3) is inside the triangle

Step-by-step explanation:

Orthocenter is the intersection of altitudes.

We'll calculate the slopes of the two sides and their altitudes ad find the intersection.

m = (3 - 5)/(4 - (-1)) = -2/5

<u>Perpendicular slope:</u>

-1/m = 5/2

<u>Perpendicular line passes through S(-1, -2):</u>

y - (-2) = 5/2(x - (-1)) ⇒ y = 5/2x + 1/2

m = (-2 - 3)/(-1 -4) = -5/-5 = 1

<u>Perpendicular slope:</u>

-1/m = -1/1 = -1

<u>Perpendicular line passes through Q(-1, 5):</u>

y - 5 = -(x - (-1)) ⇒ y = -x + 4

The intersection of the two lines is the orthocenter.

<u>Solve the system of equations to get the coordinates of the orthocenter:</u>

5/2x + 1/2 = x + 4
5x + 1 = -2x + 8
7x = 7
x = 1

<u>Find y-coordinate:</u>

y = -1 + 4 = 3

The orthocenter is (1, 3)

If we plot the points, we'll see it is inside the triangle

The following graphs show the sampling distributions for two different point estimators, R and W, of the same population paramet

Sidana [21]

The graphs are illustrations of biased and unbiased distributions.

The true statement is (d) R is biased, and W is unbiased

<h3>How to determine which of the graph is biased</h3>

From the graph, we have the following highlight

The population parameter of graph R is at the right of the distribution
The population parameter of graph W is at the center of the distribution

The above means that:

Graph R is biased, and graph W is unbiased

Which expression is equivalent to log3(x + 4)?

dangina [55]

Answer:

log[3(x+4)] is equal to log(3) + log(x + 4), which corresponds to choice number three.

Step-by-step explanation:

By the logarithm product rule, for two nonzero numbers $a$ and $b$ ,

$\log{(a \cdot b)} = \log{(a)} + \log{(b)}$ .

Keep in mind that a logarithm can be split into two only if the logarithm contains the product or quotient of two numbers.

For example, $3(x + 4)$ is the number in the logarithm $\log{[3(x + 4)]}$ . Since $3(x + 4)$ is a product of the two numbers $3$ and $(x + 4)$ , the logarithm $\log{[3(x + 4)]}$ can be split into two. By the logarithm product rule,

$\log{[3(x + 4)]} = \log{(3)} + \log{(x + 4)}$ .

However, $\log{(x + 4)}$ cannot be split into two since the number inside of it is a sum rather than a product. Hence choice number three is the answer to this question.
