Answer:
k=9
Step-by-step explanation:
K=9, because if you plug in 9 as k(2(9)=18)the equation is true.
Answer:
61%
Step-by-step explanation:
it's really simple just take the percentage of both numbers, 42% and 19% and add them together and whatever the sum is, is gonna be your answer!
There's 31 days in December so $125*31 is $3,875.
Question One
y = v - 1/2 g t^2 Subtract v from both sides.
y - v = - 1/2 gt^2 Multiply both sides by - 1
-(y - v) = 1/2gt^2 Remove the brackets.
v - y = 1/2 gt^2 Divide by g
(v - y)/g = 1/2 t^2 Multiply by 2 on both sides
2(v - y)/g = t^2 Move the 2 to the denominator on the left.
(v - y) / 0.5g = t^2 Take the square root of both sides.
sqrt [ (v - y) / 0.5g ] = t
Answer: B or second one down <<<<<<<
Question Two
There are no minuses in the answer. That eliminates 2 and 3
km^2 - c = n Add c to both sides.
km^2 = c + n divide both sides by k
m^2 = [c + n]/k Take the square root of m^2
m = sqrt [(c + n)/k]
Answer A or the first one.
Problem 3
This is an estimation question. One value of x is <0 the other > 0
The two graphs cross when x = a bit over 2 and x < about - 5
The answer is C 2.1 and - 5.1 about.
Answer: 2.1 and -5.1
Answer: C <<<<<<<<<
Answer:
Step-by-step explanation:
For this case we have this point given (5,-3) and we want to create an slope intercept formula given by:
And this equation needs to be parallel to y= 3x-1 so then the slope needs to be equal m =3 and then we can use the point given to find the intercept b like this:
And the formula for the slope would be given by:
