$\large \underline{ \mathbb{QUESTION:}}$

The lifeguard of the beach resort is on his post which is 4 m high. A boy in the pool is 9 meters away from him. Find the angle of depression from the lifeguard to the boy.

$\large\underline{ \mathbb{ANSWER \: \& \: SOLUTION:}}$

$\large \tt{ tan \: x \: = \: \frac{opposite}{adjacent} }$

$\large \tt{tan \: x \: = \: \frac{4}{9}}$

$\large \tt{ \: \: \: \: \: \: \: \: x \: = \: tan ^{ - 1} \: (0.444)}$

$\large \tt {\: \: \: \: \: \: \: \: x \: = \: 23.96 ^{o} }$

$\:\:\:\:\:\:\:\: \large \boxed{\tt{\red{ x \: = \: 24 ^{o} }}}$

Therefore the angle of depression from the lifeguard to the boy is 24°.

Multiply the numbers on the major axis which are 2 and -9 to get -18. Subtract from that 3*4 = 12. So -18-12 = -30. That's the determinant.

Calculate the length b to two decimal places.

Andrej [43]

Answer:

B. 21.64

Step-by-step explanation:

We have been given a triangle and we are asked to find the length of AC (b).

We will use law of cosines to find the length of side AC.

$c^{2}=a^{2}+b^{2}-2ab \text{ cos }\theta$

Upon substituting our given values in the formula we will get,

$(AC)^{2}=15^{2}+12^{2}-2\times 15\times 12 \text{ cos}(106)$

$(AC)^{2}=225+144-360\text{ cos}(106)$

$(AC)^{2}=369-360(-0.275637355817)$

$(AC)^{2}=369+99.22944809412$

$(AC)^{2}=468.22944809412$

Upon taking square root of both sides of our equation we will be get,

$AC=\sqrt{468.22944809412}$

$AC=21.6386101238993629\approx 21.64$

Therefore, the length of b is 21.64 and option B is the correct choice.

Part A A high school athlete ran the 100 meter sprint in 13.245 seconds. Round the time to the nearest tenth.Part B Explain how

amid [387]

Answer:

t = 13.2 s

Step-by-step explanation:

Given that,

An athlete ran the 100 meter sprint in 13.245 seconds. We need to round off the time to the nearest tenth.

Here, t = 13.245 s

In order to round off to the nearest tenth, thousandths place and hundredth place gets eliminated.

So, t = 13.2 s

So, time is 13.2 seconds.
