Tangent is opp/adj. In this case, we are given the adj and need to find the opp. Let's set up a ratio:
$tan(25) = \frac{AC}{8.6}$

Solve for AC:
$8.6tan(25) = AC = 4.01$

So, since it says round to the nearest tenth, your answer is AC = 4.0 or 4 units.

|AC|
------ = tan 25 deg, so |AC| = 8.6 tan 25 deg
8.6 8.6 (0.466) = 4.01 units (answer)

From 1995-2005, the hourly pay for lifeguards at an outdoor swimming pool increased by 2% per year. The hourly pay, P(t), in dol

12345 [234]

Answer:

The hourly pay for the lifeguards in 2001 was of $6.31.

Step-by-step explanation:

The hourly pay, in dollars, in t years after 1995, is given by the following equation:

$P(t) = 5.60(1.02)^{t}$

What was the hourly pay for the lifeguards in 2,001?

2001 is 2001 - 1995 = 6 years after 1995. So this is P(6).

$P(t) = 5.60(1.02)^{t}$

$P(6) = 5.60(1.02)^{6} = 6.31$

The hourly pay for the lifeguards in 2001 was of $6.31.

The two figures are similar. Find the ratios (red to blue) of the perimeters and of the areas. Write the ratios as fractions in

vesna_86 [32]

Answer:

see explanation

Step-by-step explanation:

The perimeters of the similar figures have the same ratio as the sides.

ratio of perimeters = $\frac{11}{6}$

ratio of areas = 11² : 6² , that is 121 : 36

ratio of areas = $\frac{121}{36}$

Find the nth term: 8, 18, 28, 38, 48....

Ivanshal [37]

Answer:

The ninth term? That would be 98.

Step-by-step explanation:

Notice how the numbers add 10 every time. If we keep doing that pattern until we get the ninth number, then we get this:

8, 18, 28, 38, 48, 58, 68, 78, 88, 98

Therefore, the answer is 98.
