The number of a particular fish in thousands x years after 1972 can be modeled by f(x)=230(0.886)x. estimate the year when the number of fish reached 99 thousand.

The year is 1979.

Step-by-step explanation:

Given:

The function relating fish population and number of years since 1972 is:

Now, when the fish population reaches 99 thousand, it means that . Now, plugging in in the above equation and solving for . This gives,

Therefore, the year after 7 years passed since 1972 is given as:

1972 + 7 = 1979.

So, the year when the number of fish reaches 99 thousand is 1979.

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
