60
D>0, there are 2 distinct real roots

Explanation:

3x2+6x−2=0
a=3,b=6,c=−2

The formula for discriminant is b2−4acSubstitute the given values.

b2−4ac
(6)2−4(3)(−2)
=60
therefore, D>0, there are 2 distinct real roots

Discriminant, not discrimination. I'm not discriminating against you. ;)

You must re-write 3x^2+6x=2 in standard form: <span>3x^2 + 6x - 2

Here a=3, b=6 and c= -2

The discriminant is b^2 - 4ac. Here, it's 6^2 - 4(3)(-2), or 36 + 24, or 60.

This quadratic has two real, unequal, zeros.</span>

Find which term in the geometric sequence 1,3,9,27,... is the first to exceed 7,000.

Zielflug [23.3K]

The common ratio between terms is 3, so the sequence has general $n$ -th term

$a_n=3^{n-1}$

for $n\ge1$ . The term exceeds 7000 when

$3^{n-1}>7000\implies n-1>\log_37000\implies n>1+\log_37000\approx9.06$

which means the first time $a_n$ exceeds 7000 occurs when $n=10$ . Indeed,

$a_{10}=3^{10-1}=19,683$

while the previous term would have been

$a_9=3^{9-1}=6561$

6m+7n+5m−3n simpified

diamong [38]

Answer:

11m + 4n

Step-by-step explanation:

when two numbers with the same variable are added together or subtracted the result is just the numbers added or subtracted. So you can add 6m and 5m to get 11m. and you can subtract 3n from 7n to get 4n

11m + 4n

6) A normal die is rolled.

Scilla [17]

Answer:

Three out of six chance

Step-by-step explanation:

There is a three out of six chance because they don’t have six numbers and three of them aren’t even so that will make it a three out of six chance. The probability of the dice landed on a one is a one out of six chance because there is only one of the number ones. I hope that’s helpful
