Given a table, with an input (x) and output (y) , you could actually use the slope formula to get the rate of change because slope is the same thing as rate of change. If you recall, the slope formula is (y2-y1)÷(x2-x1)
Just pick two points from the chart and plug them in and that is your rate of change
Answer:63 cm
Step-by-step explanation:
Given
The scale of creation is 2:9
The width of the toy wheel is 14 cm
Suppose x is the actual width of the truck
Thus, the width of actual truck is 63 cm
y = ax^2
If the absolute value of a is <1 the graph is wider than when a = 1
If the absolute value of a is >1 the graph is narrow than when a = 1
The only function that fits that description is
y = 2x^2
38 degrees.
EXPLANATION
There are 2 angles.
The angles must add up to 180.
So taking 180 and subtracting the already known angle, of 142.
Will get us with 38.
We can check the work by doing 38 + 142.
Hope this helps! have a gud day
Answer:
Addition should be performed last, because of PEMDAS.
Step-by-step explanation:
in pemdas multiply/divide comes before add/subtract so therefore you would multiply 7 x 4 first, even though addition comes before it in the problem.
