Answer:
a) (-2,-1) b) (-3,0) & (-1,0)
Step-by-step explanation:
For the first part, the turning point is simply where the graph curves. We can see that that happens on (-2, -1).
For the second part, the roots of the equation are simply when the graph crosses the x-axis. This happens twice, at (-3,0) and (-1,0)
The diagonal line is the hypotenuse of a triangle whose sides are both 50 yds, so you can use Pythagoras (a^2 + b^2 = c^2) to find the answer. 50 × 50 = 2500, and 2500 + 2500 = 5000. Because 5000 is c^2, the answer is D) √5000. I hope this helps!
Answer:
47.856
Step-by-step explanation:
We will use
SOH
CAH
TOA
to solve this
we have the adjacent length, but need the hypotonouse
which means that we will use CAH
we have
cos(43)= 35/p
solve for p
47.856
For a given x, the value on the blue line is about 1/2 the value on the black line. The appropriate choice is
y = (1/2)x
$35,000 times 20% you figure that out you get $7,000 so the core value of the car $35k-7,000 after four years is 7,000 is the value after four years
