We can find the slope by using the formula y2-y1/x2-x1. y2 and x2 are our second y and x coordinates, meanwhile y1 and x1 are our first y and x coordinates. If we plug in our numbers, we get -1-5/6-(-3). This gives us -1-5/6+3. -1-5/6+3 is -6/9. -6/9 is equal to -2/3. The answer is B.

Answer:

-2/3

Step-by-step explanation:

The slope of a line can be represented as \frac{y_{2} -y_{1} }{x_{2}- x_{1} } where (x1, y1) and (x2, y2) are points on the line. We can substitute the points given, (-3, 5) and (6, -1), to calculate the slope:

\frac{-1-5}{6-(-3)} =\frac{-6}{6+3} =\frac{-6}{9} =-\frac{2}{3}

There are two calculus classes at your school classes have a class average of 75.5 the first class as a standard deviation of 10
DENIUS [597]
To compare the two classes, the Coefficient of Variation (COV) can be used.

The formula for COV is this:
C = s / x

where s is the standard deviation and x is the mean

For the first class:
C1 = 10.2 / 75.5
C1 = 0.1351 (13.51%)

For the second class:
C2 = 22.5 / 75.5
C2 = 0.2980 (29.80%)

The COV is a test of homogeneity. Looking at the values, the first class has more students having a grade closer to the average than the second class.

An initial population of 20 rabbits triples every half year. The function f(x) = 20(3^x) gives the population after x half-perio
luda_lava [24]

The number of rabbits that there will be in 3 years is 14,580.

<h3>What is the number of rabbits in 3 years?</h3>

The growth rates of the rabbits is an exponential growth. The formula that can be used to represent the population of the rabbits in 3 years is:

f(x) = 20(3^x)

Where x represents the number of years. The number of years is 6(3 x 2)

20 x 3^6 = 14,580

How can the function f(x)=x2-6x+8 be rewritten to determine its minimum value?
ki77a [65]

Answer:

Minimum value of f(x) = -1.

Step-by-step explanation:

We convert it to vertex form:

x^2 - 6x + 8

= (x - 3)^2 - 9 + 8

= (x - 3)^2 - 1

The minimum value occurs when (x - 3)^2 = 0  because a square has a minimum value of zero ( it cannot be negative for real values of x).

So  the function has a minimum value of -1.
