Step-by-step explanation:
V=S/T(the formula)
V= 375/5
V=75
Answer:
y = x² + x - 4
Step-by-step explanation:
Given roots x = a and x = b, then the factors are
(x - a) and (x - b)
The function is then the product of the factors
y = a(x - a)(x - b) ← where a is a multiplier
Given roots are x = - 4 and x = 2 then the factors are
(x - (- 4)) and (x - 2), that is (x + 4) and (x - 2), thus
y = a(x + 4)(x - 2)
To find a substitute (6, 20) into the function
20 = a(6 + 4)(6 - 2) = a(10)(4) = 40a ( divide both sides by 40 ), thus
a = =
y = (x + 4)(x - 2) ← expand factors
= (x² + 2x - 8) ← distribute
y = x² + x - 4
Distance =

Answer:
look at the picture above
I will try my best to assist you with your problem.
We need to factor the equation, so you must start by note that leading coefficient is 1 so factor would looks like (R + ?)(R + ?) = 0 because 1*1 = 1
And we know that 1*8 = 8 and 1 + 8 = 9 so then we have (R + 8)(R + 1)=0
Now we can split factors into two equations: either R+8 = 0 R+1 = 0.
Solve both equation and we get R = -8 or R = -1
Hope I helped!
Good Luck!
