Answer:

D) 0.9

Step-by-step explanation:

The common ratio of a sequence is the amount you multiply a term by to get the next one. To find this number divide the second term by the first term, so 36/40. This will give you 0.9, to check your answer take the first term and multiply it by the common ratio a few times; you should get the exact sequence listed in the question.

Rasek [7]

Answer:

10.875 total, 1.5 times each are below.

Step-by-step explanation:

1.5 (1 1/2) x 1.5 = 2.25

0.5 (2/4) x 1.5 = 0.75

0.125 (1/8) x 1.5 = 1.875

4 x 1.5 = 6

2.25 + 0.75 + 1.875 + 6 = 10.875 total

use the pythagorean theorem to find the missing side length. 2 write sin, cosine, tangent of each angel.​
Harlamova29_29 [7]

Answer:

1) x=5\sqrt{3}

2) sin(a)=5\sqrt{3}/14

sin(b)=11/14

cos(a)=11/14

cos(b)=5\sqrt{3}/14

tan(a)=5\sqrt{3}/11

tan(b)=11/5\sqrt{3}

Step-by-step explanation:

 The Pythagorean Theorem is:

a^{2}=b^{2}+c^{2}

Where a is the hypotenuse and b and c are the legs.

The missing side lenght is one of the legs, then you must solve for one of them. Therefore, this is:

x=\sqrt{(14yd)^{2}-(11yd)^{2}}=5\sqrt{3}yd

MEASURE OF ANGLE:

Keep the identities on mind:

sin\alpha=opposite/hypotenuse

cos\alpha=adjacent/hypotenuse

tan\alpha=opposite/adjacent

Susbstitute values, then:

sin(a)=5\sqrt{3}/14

sin(b)=11/14

cos(a)=11/14

cos(b)=5\sqrt{3}/14

tan(a)=5\sqrt{3}/11

tan(b)=11/5\sqrt{3}
