Find the rate of change for:
bicycling 3 mi in 15 min and 7 mi in 55 min
The rate of change is 10.
What is rate of change?Rate of change is used to mathematically describe the percentage change in value over a defined period of time, and it represents the momentum of a variable. The rate of change is equal to the change in y values divided by the change in the x-values.
For the given situation,
Bicycling involves 3 miles in 15 min and 7 miles in 55 min.
Here consider miles in x axis and minutes in y axis.
So, [tex](x1,y1) = (3,15)[/tex] and [tex](x2,y2)=(7,55)[/tex]
The rate of change is
⇒ [tex]\frac{y2-y1}{x2-x1}[/tex]
⇒ [tex]\frac{55-15}{7-3}[/tex]
⇒ [tex]\frac{40}{4}[/tex]
⇒ [tex]10[/tex]
Hence we can conclude that the rate of change is 10.

We can write the information we know as ordered pairs. The independent variable, or x, in this case would be the amount of time, and the dependent variable, or y, would be the amount of money. This is because the amount of money charged changes depending on the amount of time. This gives us the ordered pairs (3, 26) and (5, 42). Using the formula for slope we have:
. A slope of 8 tells us that the hourly rental is $8. We can use this to back up and see what the rental fee is. When renting the kayak for 3 hours, Jake paid 26. We know that it costs $8 per hour; 8(3) = 24. This leaves us 26-24=$2 for the rental fee. The equation would then be
y = 8x + 2.
Writing this as a function would be f(x) = 8x + 2.
To graph this, we would label the x-axis as time (hours) and the y-axis as money (dollars). We would go up to the y-intercept, 2, and plot our point. (The y-intercept is 2 because in the form y=mx+b, b is the y-intercept; that's where our 2 is.) From here, we know the slope is 8=8/1, so we would go up 8 and over 1 to the right to plot our next point. Then we would draw our line between these two points.

Step Work Reasoning
−7.9 + 8.2 − 3.4 + 2.1 Original problem
1 −7.9 + 8.2 + (−3.4) + 2.1 Additive inverse
2 −7.9 + (−3.4) + 8.2 + 2.1 Commutative property

She did not make any errors.
Step 1: She wrote −3.4 incorrectly as + (−3.4).
Step 2: She identified changing the order of the numbers as the commutative property, which is incorrect.
Step 3: She identified changing the grouping of the numbers as the associative property, which is incorrect.
Answer:
Step 1 it says Additive inverse, that is not additive inverse. Additive inverse is the opposite of a number. There is no opposite number in the problem. And step 5 is the answer, it shouldn't be simplify. Hope that helps! :)

It constitutes less than half of all nonnative species introductions.
b.
The revenue brought in from these industries is relatively small.
c.
It is difficult to prevent since ship hulls begin, conduct, and end voyages in water.
d.
It is best combated by chemical treatments.
Answer: C. It is difficult to prevent since ship hulls begin, conduct, and end voyages in water.
Step-by-step explanation:
The option that is true concerning hull fouling from commercial shipping and recreational boating is; C: It is difficult to prevent since ship hulls begin, conduct, and end voyages in water.
What is Hull Fouling?Hull fouling is a phenomenon that arises due to the accumulation of marine growth that leads to reduction in speed of the vessel, increase in the bunker consumption and also the accumulation of more cleaning costs.
Now, this marine growth such as water hyacinths and others are very hard to prevent because the ship lull is not something that can be brought to land before movement as it starts and ends it's journey inside the water.
Thus, the correct option is C.

let the function be f defined by f (x) = 12 - 5x
(a) is it true that f (0) = 0 ? explain why or why not.
(b) evaluate f (-1)
(c) what value of a will make the equation f (a) = 6 true?
Answer
a)no
Step-by-step explanation:
a)12-5(0)
=12 not 0
b)12-5(-1)
=17
c)12-5x=6
-5x=6-12
x=1.2
hope it helps:)
Evaluating the function, it is found that:
a) No, since [tex]f(0) = 12[/tex], as when we replace x by 0, the value of y is 12.
b) [tex]f(-1) = 17[/tex]
c) [tex]a = \frac{6}{5}[/tex]
The function given is:
[tex]f(x) = 12 - 5x[/tex]
Item a:
f(0) is given by:
[tex]f(0) = 12 - 5(0) = 12[/tex]
So it is not true, since [tex]f(0) = 12[/tex].
Item b:
[tex]f(-1) = 12 - 5(-1) = 12 + 5 = 17[/tex]
Item c:
This is the value of x when f(x) = 6, thus:
[tex]12 - 5x = 6[/tex]
[tex]5x = 6[/tex]
[tex]x = \frac{6}{5}[/tex]
Thus:
[tex]a = \frac{6}{5}[/tex]

Answer:
y = x + 3
Step-by-step explanation:
To know which of the equations represent the relationship between x and y, you need to substitute the x and y values into the equation. If when the equation is solved, the left-hand and right-hand side of the equation equal each other and hence the equation is true, then the equation must be correct in expressing the relationship between the x and y values. If not, then it is not correct.
As this question is only dealing with linear equations, we know that the gradient of the line is constant and hence the rate of change in x and y values is constant. Therefore, we can choose to substitute any of the given combinations of x and y values into the equation to obtain the correct equation. As it is easier to use smaller numbers for smaller calculations, we'll use the first combination of x = 1 and y = 4 .
Equation No. 1 : y = 3x + 1 where x = 1 , y = 4 and x = 2 , y = 5
( 4 ) = 3 ( 1 ) + 1
4 = 4
However, as this equation has a constant not equal to 1 in front of the x variable and hence a different gradient to the other equations, we will substitute the second combination of x and y values.
( 5 ) = 3 ( 2 ) + 1
5 = 6
Therefore, equation is false / incorrect.
Equation No. 2 : y = x + 1 where x = 1 , y = 4
( 4 ) = ( 1 ) + 1
4 = 2
Therefore, equation is false / incorrect.
Equation No. 3 : y = x + 3 where x = 1 , y = 4
( 4 ) = ( 1 ) + 3
4 = 4
Therefore, equation is true / correct.
Equation No. 4 : y = x - 3 where x = 1 , y = 4
( 4 ) = ( 1 ) - 3
4 = - 2
Therefore, equation is false / incorrect.

Kathy Is 12 years old and Ben is 16 years old. How many years ago was Ben three times Older than Kathy?
Setting up an equation to represent the scenario, we can conclude that Ben was 3 times older than Kathy 10 years ago.
Present age :
Kathy, k = 12 Ben, b = 16Serting up the equation thus :
Let the number of years = x
16 - x = 3(12 - x)
16 - x = 36 - 3x
Collect like terms
-x + 3x = 36 - 16
2x = 20
x = 10
Hence, Ben was 3 tines older than Kathy 10 years ago.

Answer:
Angle 3 = 23 degrees Angle 8 = 157 degrees
Step-by-step explanation:
Since Angle 2 and Angle 3 are vertical angles, they have the same value.
As you see for Angle 8, Angle 8 is vertical angles with Angle 5.
Angle 5 corresponds with Angle 1 which is the same value since these lines are parallel.
Angle 1 and Angle 2 added together will have a sum of 180.
So substitute Angle 5 for Angle 1.
Angle 5 + 23 =180
Angle 5 = 157 degrees
And we know Angle 5 = Angle 8
So Angle 8 = 157 degrees.

gcd(2^57,885,161 - 1, 2^43,112,609 - 1) =1
tan(π/4) = 1
