Answer:

x ≤ 13.2.

Step-by-step explanation:

6  ≥  x/2.2

Multiply both sides by 2.2:

6 * 2.2 ≥ x

Using the triangle pictured, find the measure of side AB. Round your answer to the nearest tenth. A) 1.6 B) 2.2 C) 2.7 D) 3.3
Yuki888 [10]

Answer:

Option B (AB = 2.2 units).

Step-by-step explanation:

The diagram shows that there are two sides given and one angle is given. Therefore, the sine rule must be used to solve the question. The sine rule can be written as:

sin ABC / AC = sin BAC / BC.

Plugging ABC=72 degrees, AC=2.5, and BC=2.1 in the sine rule gives:

sin 72 / 2.5 = sin BAC / 2.1.

Cross multiplying gives:

sin BAC = (2.1*sin 72)/2.5.

sin BAC = 0.79888747368.

Taking sin inverse on both sides gives:

BAC = arcsin (0.79888747368) = 53.0239949 degrees.

To find AB, first, the angle ACB is required. To find that angle, use the triangular law of angles. All the three angles sum up to 180 degrees. Therefore ACB = 180 - 72 - 53.0239949 = 54.9760051  degrees.

Now applying the Sine Rule to find AB:

sin ACB / AB = sin ABC / AC.

sin (54.9760051) / AB = sin 72 / 2.5.

AB = (2.5*sin (54.9760051))/sin (72) = 2.2 (to the nearest tenth).

Therefore, AB = 2.2 units, i.e. Option B!!!

Solve the following equation. log Subscript 2 Baseline (3 x plus 7 )equals 5 The solution set is StartSet nothing EndSet . ​(Sim
tigry1 [53]

Answer: x=\dfrac{25}{3}

Step-by-step explanation:

The given equation : \log_2(3x+7)=5

Using logarithmic property : \log_a N=M\to N=a^M

The given equation will be equivalent to (3x+7)=2^5

\Rightarrow\ 3x+7=32

Subtract 7 from both sides , we get

3x=25

Divide both sides by 3 , we get

x=\dfrac{25}{3}

Hence, the solution is x=\dfrac{25}{3}
