You know the formula of discriminant

a b
c d
that means ad-bc
So we have an equation
(-12)x3-(2f)x(-w²)= 2k x 3- (-14)x(-81)
0r -36 +2fw²= 6k- 1134
And 2fw²-6k+ 1098=0
But I did not know what is variable here?

What are the first and last terms of this geometric series

11Alexandr11 [23.1K]

ANSWER

E. 10 and 640

EXPLANATION

The given series is

$\sum_{i=1}^45 \times 2^{2i-1}$

To find the first term of the series we substitute i=1 to get,

$a_1 = 5 \times {2}^{2 \times 1 - 1}$

$a_1 = 5 \times {2}^{ 1} = 10$

For the last term of the series, we substitute i=4 to obtain,

$a_4 = 5 \times {2}^{2 \times 4 - 1}$

$a_4 = 5 \times {2}^{7}$

This implies that,

$a_4 = 5 \times 128 = 640$

Therefore the correct answer is E

Angle θ = 30°

Opposite = 1

Adjacent = √3

The value of Tan 30° can be obtained as illustrated below:

Tan θ = Opposite / Adjacent

Tan 30 = 1/√3

Thus, the value of Tan 30° is 1/√3

Nadya [2.5K]

Answer:

144 people were originally at the party.

Step-by-step explanation:

18 boys is one fifth of the second boys population, so the second population is 18x9 = 162. The original population would be 162-18, which equals 144.

Which number satisfies the inequality 9h + 15 > 55?

zalisa [80]

When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.

9h + 15 > 55

Subtract 15 from each side: 9h > 40

Divide each side by 9 :  h > 40/9

Any number greater than (4 and 4/9) satisfies the inequality.
