Answer:
There will be 4 blue marbles
Step-by-step explanation:
Yellow to blue marbles is in a ratio of:
5:10
the representative sample is:
2:x
simplee cross multiplication can be aplied
5x = 2*10
5x = 20
divide both sides by 5
x = 4
there should be four blue marbles
Use Pythagorean theorem:
9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80
now divide both terms in V by that:
u = 9/sqrt(80)i - 1/sqrt(80)j

Answer:
I believe your answer is correct.
Step-by-step explanation:
Please, for clarity, indicate exponentiation using the " ^ " symbol.
y = - 3x^5 ("Negative three times the 5th power of x")
y = 3x^8
y - -3(0.5)^x
y = -2^4
An exponential function has an exponent which is variable, where the base stays constant; the base cannot be a negative number or a zero. The third answer choice is the correct one, as we raise the constant 0.5 to the power x:
y = -3(0.5)^x
