$\implies {\blue {\boxed {\boxed {\purple {\sf {20}}}}}}$

$\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:EXPLANATION:}}}$

$= ( {2}^{2} + {4}^{2} )$

$= [(2 \times 2) + (4 \times 4)]$

$= (4 + 16)$

Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only) (6 points)

wolverine [178]

Answer:

35.68°

Step-by-step explanation:

In the picture attached, the triangle is shown.

From sine definition:

sin(y) = opposite/hypotenuse

The leg measuring 7 units is opposite to angle y, and the hypotenuse measures 12 units, therefore:

sin(y) = 7/12

y = arcsin(7/12)

y = 35.68°

Indicate a general rule for the nth term of this sequence. -6b, -3b, 0b, 3b, 6b. . .

GREYUIT [131]

Answer:

a(n) = -16b + (n - 1)(3b)

Step-by-step explanation:

First term is -6b.

Common difference is 3b; each new term is equal to the previous one, plus 3b.

Formula for this arithmetic sequence is

a(n) = -16b + (n - 1)(3b)
