Answer:
The vertical height is
Step-by-step explanation:
we know that
In the right triangle ABC
see the attached figure
To find the height h apply the Pythagoras Theorem
we have
substitute
(x) = ax 2 + bx + c has a negative leading coefficient and the vertex that has a negative y-coordinate. Determine the number of
real zeros of the function.
1 answer:
The number of real zeroes are the x intercepts or where the graph touches the x axis
negative leading coeficnet means it opens down
negative y coordinate means that the highest point is below the x axis
since it opens down and it is below the x axis, there is no x intercept or real solution (see attachment)
thereforr there are no real roots, there are zero real roots, nada, zip

The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp.
calculates three times a year, not just once a year.
3 times a year
so x becomes 3x
Take log on both sides
Use log property and move exponent before log
Divide both sides by x
log 4 = 3 log(1+r)
Solve for '1+r'
log 4 = log(1+r)^3
Remove log from both sides
4 = (1+r)^3
take cube root on both sides
1.584740= 1+r
1+r = 1.59
so equation becomes
1+r = 1.59
subtract 1 from both sides
So r= 59 = 59%
So growth factor is 59%
