Solve this quadratic equation using the quadratic formula. 5 - 10x - 3x2 = 0
horsena [70]

Answer:

x = (-5 ± 2√10) / 3

Step-by-step explanation:

5 − 10x − 3x² = 0

Write in standard form:

-3x² − 10x + 5 = 0

Solve with quadratic formula:

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ -(-10) ± √((-10)² − 4(-3)(5)) ] / 2(-3)

x = [ 10 ± √(100 + 60) ] / -6

x = (10 ± 4√10) / -6

x = (-5 ± 2√10) / 3

Chi chi can hit The golf ball 72 yards. Rory Can hit a golf ball 24 yards. How many times further can Chi chi hit a golf ball th
ivanzaharov [21]

Answer:

Chi chi canhit a golf ball three times further than Rory.

Step-by-step explanation:

To compare the distance between the two golfers, we can set up a ratio:

\frac{Chi chi Distance}{Rory Distance} = \frac{72}{24} =\frac{3}{1}

Since the distance that Chi chi can hit the ball is 3:1 the distance that Rory can hit the ball, than Chi chi can hit the golf ball three times further.  When reducing a ratio or fraction to lowest terms, you need to divide the numerator and the denominator by the same factor.  Since 72 can be evenly divided by 24, we can divide both the numerator and the denominator by 24 to get 3:1.

Ms. Coleman's class has already collected 403 cans for a food drive, but the class wants to collect a total of at least 1,000 ca
pochemuha
We need to figure out how many more cans they need to bring.  We figure this out by subtracting 403 from 1,000, which gives us 596 more cans.  We now divide 596/28, to find how many each student would need to bring.  This equals 21.3.  You might want to mention that each student can't bring .3 of a can, so the answer could be 22 also.
