Answer:
0/8
Explanation:
There is no number greater than 10 on the spinner, so there is a 0/8 chance that the spinner will land on a number greater than 10.
Answer:
f(x) = (x - 4)² - 4
Step-by-step explanation:
∵ The general form of the Parabolic function is :
f(x) = (x - h) + k ⇒ where point (h , k) is the turning point
∵ The turning point is (4 , -4)
∴ f(x) = (x - 4)² + -4 = (x - 4)² - 4
To check the answer:
Use the point (6 , 0) ⇒ 0 = (6 - 4)² - 4 ⇒ 0 = 4 - 4
∴ f(x) = (x - 4)² - 4
From all this information we can come up with a few equations to work with...
first we have that the worth of each coin times the number of those coins all added together equals 4.65
here I have n = nickels, d = dimes, and q = quaters
then we are told that there are "three more quarters than dimes"
which translates to the equation
or
we are also told that there are "twice as many nickels as quarters"
this translates to
to solve for quarters, we plug in d (in terms of q) and n (in terms of q) into the first equation we created.
then we distribute and start trying to solve for
then add like terms
then add 0.30 to both sides
then divide both sides by 0.45
therefore our answer is B) 11 quarters
