Answer:
57.5
Step-by-step explanation:
The constant of proportionality is "k" in the equation ...
y = kx
It can be found from values of x and y using ...
k = y/x
For the given values, it is ...
k = (287.5 mi)/(5 h) = 57.5 mi/h
The constant of proportionality relating miles to hours is 57.5.
Answer:
I'd use A = πr^2
The area is 28.3 if we're using 3.14 as pi (rounded to the nearest tenth)
Honestly this sounds like its asking to put it in word form so " three times m"
Answer:
y=0.5+sqrt(17)
Step-by-step explanation:
Let y=sqrt{4+sqrt{4+...+sqrt(4)}
y=sqrt(4+y). (Since it's an infinite series)
y^2=4+y, y=0.5-sqrt(17) or 0.5+sqrt(17). We will omit the negative since root values are positive.
Answer:
y = -2x^2 - 8x + 0
Step-by-step explanation:
By "standard form," I assume you mean "y = ax^2 + bx + c."
Your f(x)= -2x^2-8x has no constant term. But that's OK!
In standard form, then, you have y = -2x^2 - 8x + 0, or just y = -2x^2 - 8x.
Recognizing that this is a quadratic function, we can write:
a = -2, b = -8 and c = 0.
If this isn't the "standard form" that you had in mind, please share your version of "standard form."
