Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

If two lines are coplanar, then lines should be parallel or they should intersect each other.

It means, perpendicular lines always intersect to each other but parallel lines never.

So, If the lines are perpendicular then it must intersect, other wise the lines never intersect.

so, the lines are coplanar.

Hence, Option 'c' is correct.

Here are the first four terms of a sequence.

Nataly_w [17]

Answer:

aₙ = 2n² + n + 1

Step-by-step explanation:

We observe that the difference of terms is 4, 7 and 15 and next level difference is 4. It means the sequence is quadratic.

We can compare this with simple quadratic sequence

1, 4, 9, 16

and find out that doubling each term gives us

2, 8, 18, 32

This is close to our sequence, write the terms as follows to find exact rule

The first term:

a₁ = 4 = 2*1² + 2 = 2*1² + 1 + 1

The second term

a₂ = 11 = 2*2² + 3 = 2*2² + 2 + 1

The third term:

a₃ = 22 = 2*3² + 4 = 2*3² + 3 + 1

The fourth term:

a₄ = 37 = 2*4² + 5 = 2*4² + 4 + 1

The nth term as per observation above is:

aₙ = 2n² + n + 1

Carolyn is using the table to find 360% of 15. What values do X and Y represent in her table?

Ganezh [65]

★ 100% of 15 = X

$\implies \mathsf{100\%\;of\;15 = \left(\dfrac{100}{100} \times 15\right) = 15}$

$\implies \mathsf{X = 15}$

★ 20% of 15 = Y

$\implies \mathsf{20\%\;of\;15 = \left(\dfrac{20}{100} \times 15\right)}$

$\implies \mathsf{20\%\;of\;15 = 3}$

$\implies \mathsf{Y = 3}$

Answers : X = 15 and Y = 3
