Use the quadratic formula -b+/-√b^2 -4(ac) / 2a
-4 +/- √(4^2 - 4(1*10) / (2*1)
X = -2 +/- i√6
Answer:
Step-by-step explanation:
The y intercept is where x = 0.
X and y are both increasing by 5.
If you add five to the bottom row of the table we see that the next row of the table is x = 0 and y = 13.
This means that (0,13) is the y-intercept and 13 is your correct answer.
Answer:
Whenever the earth, moon and sun are aligned, the gravitational pull of the moon is augmented by the gravitational pull of the sun, causing larger than average tidal ranges — meaning especially high high tides and very low low tides. These extreme tides are called “spring tides.”
Step-by-step explanation:
The length of the midsegment of an isosceles trapezoid is the sum of the two bases, divided by 2. So this means -
(base 1+base2) / 2
(12+20) / 2
32/2
Length of midsegment = 16
Answer:
64
Step-by-step explanation:
16 x 4 = 64
