Guys please help me am I right ​

Mathematics
1 answer:
Elodia [21]3 years ago
8 0

Answer:

y \leqslant 6

Step-by-step explanation:

The range is set of all y-values. The range starts from minimum value to maximum value.

We don't have minimum value (approaching negative infinity.)

We have maximum value at x ≈ 2 equal 6.

Therefore the answer is

-inf <= y <= 6. But we don't usually write that. Instead, we cut out -inf and we get —

y \leqslant 6

Use the geometric mean to find the 7th term in a geometric sequence if the 6th term is 12 and the 8th term is 27. 20 19.5 18 17
Lesechka [4]
A₆ =12

a₇ = ?? = x

a₈ 27

In this case x is the geometric mean & as per the formula
geometric mean of 2 numbers =√(a₆ * a₈) = √(12*27)
& x=18.
Proof:
Find the common ratio between a₇ & a₆ ==> = ( x) / 12
now find the common ration between a₈ & a₇ ===> =27 / (x)
x/12 = 27/x ===> x² = 12*27 ==> x² = 324 & x =√324 = 18

Expand and simplify (2x+5y) (x-3y)
Dmitry [639]
Should be simple:

Let's take this one at a time.

2x(x-3y)

You'd get:
2x^2-3xy
for the first one.

2nd one:
5y(x-3y)
you'd get:
+5xy-3y^2

Put them both together:
2x^2-3xy+5xy-3y^2

Combine like terms.

Your Answer:
2x^2+2xy-3y^2

11 relaxing after work. the 2010 general social survey asked the question: "after an average work day, about how many hours do y
Bogdan [553]
A confidence interval tells us how many percents we are confident about the range of a parameter. In this problem, <span>a 95% confidence interval for the mean number of hours spent relaxing or pursuing activities they enjoy was (1.38, 1.92). That means we're 95% confident that the Americans spend from 1.38 hours to 1.92 hours per day on average relaxing or pursuing activities they enjoy. In other words, 95% of the samples of the same size would have a mean number of hours relaxing or pursuing activities they enjoy between 1.38 to 1.92.</span>
