Please help me on this math problem
Fed [463]
We know the first term is 16, because f(1) = 16. Next, we can use the recursive rule provided. f(3)=1/2*f(3-1). This gives us f(3)=1/2*f(2). We know f(2) is 8. We know have f(3)=1/2*8. This is 4.

The answer is 16, 4.

Susie is solving the quadratic​
topjm [15]

Answer:

Option (D)

Step-by-step explanation:

Standard equation of a quadratic function is,

ax² + bx + c

Comparing this function with the given quadratic function,

f(x) = 2x² - 4x - 3

a = 2, b = -4 and c = -3

By using quadratic formula to get the value of x,

x = \frac{-b\pm \sqrt{b^2-4ac} }{2a}

  = \frac{-(-4)\pm \sqrt{(-4)^2-4(2)(-3)} }{2(2)}

  = \frac{4\pm\sqrt{16+24}}{4}

  = \frac{-4\pm \sqrt{40}}{4}

  = \frac{-2\pm \sqrt{10}}{2}

Therefore, Susie made a mistake in step IV.

Option (D) is the answer.

if a fish tank,8/11 of the fish have a red stripe on them.If 16 of the fish have red stripes,how many total fish are in there
Arisa [49]
8/11--------> 16

to find the total number of fish, divide 16 by 8 and multiply it by 11,

16÷8=2
2×11=22

total number of fish= 22

check,

22÷11×8=16

if you want to find the number of fish without the red stripes,

8/11--------> 16
11/11------->22
3/11--------->?

you can either subtract 16 by 22=6
or
22÷11×3=6

hope this helps......
