Answer:
{x | x > 8}

Explanation:
On the graph, the left end has a dot on x = 0, not an arrow, so the graph does not reach left of x = 0.

On the right end, there is an arrow where x = 8, which means the graph continues past x = 8.

Plant B is 6 2/3 inches tall. and C is 4 4/15 inches tall. Complete the sentences and show your reasoning

artcher [175]

Answer:

Plant C is 0.64 times as tall as Plant B

Plant C is 2.4 inches shorter than Plant B

Step-by-step explanation:

Plant B is 6 2/3 inches tall. Plant B is 20/3 inches tall.

Plant C 4 4/15 inches tall. Plant C is 64/15 inches tall.

a.) Plant C is shorter than Plant B $= \frac{64}{15} \times \frac{1}{\frac{20}{3} } = \frac{64}{15} \times\frac{3}{20} = \frac{16}{25}$ = 0.64 times.

b.) Plant C is shorter than Plant B by = $\frac{20}{3} - \frac{64}{15} = \frac{100}{15} - \frac{64}{15} = \frac{100 -64}{15} = \frac{36}{15} = 2\frac{2}{5} = 2.4$ inches

suppose a triangle has two sides of length 2 and 3 and that the angle between these two sides is 60. what is the length of the t

arlik [135]

Answer:

√7 ≈ 2.646

Step-by-step explanation:

The law of cosines is applicable. It tells you ...

c² = a² + b² - 2ab·cos(C) . . . . . where a, b, c are triangle side lengths, and angle C is opposite side c.

Filling in the given information, you have ...

c² = 2² + 3² - 2·2·3·cos(60°) = 4 + 9 - 12·(1/2) = 7

c = √7 ≈ 2.646

The length of the third side is √7, about 2.646 units.

The value of x equals 30.

Step by Step explanation:

All sides are equal so you know the angle lengths are equal. When you multiple 2x by 3 you get 6x. All angles of a triangle add up to 180 so you divide 180 by 6 and you get 30. Hope This Helps!
