Britney traveled from the school to the mall and then from the mall to the library. Alice traveled directly from the school to t
givi [52]
Britney:
School to Mall is 10 units
Mall to Library is 24 units
In total, 10 + 24 = 34, Britney traveled 34 units.

Alice:
School to Library is ___ units.
Using the Pythagorean Theorem, you can find the distance
a^2 + b^2 = c^2 this is the formula
10^2 + 24^2 = c^2 square the 10 and 24
100 + 576 = c^2 add the two values
676 = c^2 square root both sides
26 = c
School to Library is 26 units.

34 - 26 = 8 units
Britney traveled 8 units more than Alice.
Just multiply the 8 units by how many miles there are in 1 unit and you will find your answer.

The average high temperature each month in a calendar year for a city in South Carolina is represented by the function: f(x)=−x2
LuckyWell [14K]

Answer:

Average\hspace{3}rate\hspace{3}of\hspace{3}change=-7.7

Step-by-step explanation:

The average rate of change measures the average rate at which a function changes per unit time in a given interval. In another words, the average rate of change is the relationship between vertical and horizontal changes between two points of the function. So, basically if you are trying to find the average rate of change, you are trying to find the slope.

Average\hspace{3}rate\hspace{3}of\hspace{3}change=Slope=m=\frac{\Delta y}{\Delta x} =\frac{f(x_2)-f(x_1)}{x_2-x_1}

If x represents the months, then:

Let:

September=x_1=9\\December=x_2=12

So:

For:

f(x)=-x^2+13.3x+42

f(x_1)=f(9)=-(9)^2+13.3(9)+42=80.7\\\\f(x_2)=f(12)=-(12)^2+13.3(12)+42=57.6

Therefore:

Average\hspace{3}rate\hspace{3}of\hspace{3}change=\frac{57.6-80.7}{12-9} =\frac{-23.1}{3} =-7.7

the speed a car travels is inversely proportional to the time it takes to complete a 100 mile trip. which of the following graph
Tems11 [23]

Answer:

Inversely proportion states that a relationship between two variables in which the product is a constant.

If one of the variable increases, then the other decreases in proportion so that the product is unchanged.

If y is inversely proportional to x, then the equation is of the form

y = \frac{k}{x} ;  where k is the constant proportionality.

As per the given condition: Speed of a car is inversely proportional to the time it takes to complete a 100 mile trip,

Let x represents the speed of car and y represents the time taken.

From the given condition:

x \propto \frac{1}{y}

Then by definition of inversely proportional;

x = \frac{k}{y}         [Since, speed = \frac{Distance}{Time} ]

Here, k represents the distance(i.e constant) = 100 miles.

therefore, the equation becomes now;

x = \frac{100}{y} or

xy = 100

The following graph for the above equation as shown below :

Explain how you can find the sign of the product of two or more rational numbers
mr_godi [17]
If the number of positive signs is even and the number of negative signs is odd then it is negative and vice versa. If the number of positive signs is even and the number of negative signs is even then the answer is odd. If the number of positive and negative signs are odd then the answer is always negative.
