Tannis's first machine could throw a car 272727 meters. She studied her first machine and built a better one. Her second machine could throw a car 777 times as far.
How far does the second machine throw a car?
Answer:
The rate of change of the distance between the cars at that instant is 5.46 meters per second
Step-by-step explanation:
Speed of first car = 7 m/s
Speed of second car = 3 m/s
At instant, distance of first car from intersection = 5 meters
distance of second car from intersection = 12 meters
Therefore, we have
Distance between both cars at intant = √(12² + 5²) = 13 m
Rate of change of distance is given by;
2ddd/dt = d(x² + y²)/dt = 2xdx/dt + 2ydy/dt
= 26dd/dt = 2×5×7 + 2×12×3 = 142
dd/dt = 142/26 = 5.46 m/s.
That is the rate of change of the distance between the cars at that instant = 5.46 meters per second.
The graph below shows the cost of pens based on the number of pens in a pack. What would be the cost of one pen?
$0.57
$1.75
$5.50
$6.50
Answer:
$1.75
Step-by-step explanation:
Honestly, you don't really have to pay attention to the other numbers or ratios on the graph until you think you found your answer. Pay attention to whichever ratio you choose and follow these steps:
1. Identify which number is the cost and which is the amount of pens bought
2. Set it up as a division problem by using the cost and the dividend and the amount of pens as the divisor
3. After you have your answer, plot your ratio of 1:(your product) and if the line that was graphed is straight, you are correct.
PS. I used the ratio (2:3.5) to solve this problem

i did 5(-2) -4
which is -10 -4
and that will equal -14!
hope this helps u!
Answer:
-14
Step-by-step explanation:
because if x is -2 we have y=5.(-2)-4 and that's y=-10-4 and that's y=-14

4(x + 3) = 20.
Statements
Proof
4(x + 3) = 20
Given
4x + 12 = 20
4x = 8
x = 2
Answer:
x = 2
distributive property of equality, subtraction property of equality, and division property of equality
Step-by-step explanation:
(Proof is in parenthesis)
4(x + 3) = 20 (Given)
4x + 12 = 20 (distributive property of equality)
4x = 8 (subtraction property of equality)
x = 2 (division property of equality)

The closure properties of polynomials are similar to other closure properties. Which closure properties are similar to the closure properties of polynomials?
Answer:
The closure property of integers
Step-by-step explanation:
The addition closure properties of integers are similar
The closure property when adding integers are similar
It is similar because, when we add two polynomials, we get another polynomial
Also, when we add two integers, we get another integer
So we can conclude that the closure property of adding integers is similar

3 is a Name a chord that is not a diameter
Answer:
by-step explanation:
m= -(4+m)+2
solve for m
Answer:
m = -1
Step-by-step explanation:
m = - (4 + m) + 2
m = -4 - m + 2
m = -2 - m
+m +m
2m = -2
/2 /2
m = -1
Hope this helps!
Answer:
m=-1
Step-by-step explanation:
m = - ( 4 + m ) + 2
m - 2 = - ( 4 + m )
m - 2 = - 4 - m
m + m = - 4 + 2
2 m = - 2
m = - (1/2)
m = - 1
