A flagpole casts a 13-foot shadow on the ground when the sun is at a 68° angle of elevation.
Step-by-step explanation:
Step 1: List out all of the formulas for the trigonometric functions
sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent
Step 2: Find the value of h
cos(68) = 13/unknown is FALSE
cot(68) = 13/h is FALSE
sin(68) = h/unknown is FALSE
tan(68) = h/13 is TRUE
Answer: The correct option would be D
During a war, Country A led a massive assault on the beach of Country B. The beach is 6.4 miles long. At 5 AM, a ship was first spotted from either end of the beach. The angle made with the ship from one end of the beach was 47°. The angle made with the ship from the other end of the beach was 71°. Determine the distance from the ship to either end of the beach at the moment the ship was first spotted.
Answer:
5.3 miles & 6.85 miles
Step-by-step explanation:
To solve this question, I would use the sine rule
a/Sine A = b/Sine B = c/Sine C
Making a rough sketch, I have a scalene triangle with angles 47° and 71°, by default, the third angle is 61°
Given that, from my rough sketch
Angle C = 62°
Angle B = 71°
Angle A = 47°
Side c = 6.4 miles
We're looking for dudes a and b, applying our formula, we have
a/Sine 47 = 6.4/Sine 62
a/0.7314 = 6.4/0.8829
a/0.7314 = 7.25
a = 7.25 * 0.7314
a = 5.3 miles
b/Sine 71 = 6.4/Sine 62
b/0.9455 = 6.4/0.8829
b/0.9455 = 7.25
b = 7.25 * 0.9455
b = 6.85 miles
For every $3.00 the 5th grade raise, the 6th grade raises $5.00. If the 5th grades raises $36.00, how much does the 6th grade rais
Answer:

how do you do this? please helppppp!! thank youuu
Answer:
answer rounded up is -31.84
Step-by-step explanation:
So first, square root of 6 is 2.4494, and then you times that by 2, and then you do square root of 54 which equals to 7.34846, and then you times 5 by that, and then you do 2 times square root of 6 minus 5 times square root of 54. Hope it helps

How many different ways can five types of laser printer be displayed on .1 shelf in a computer store? There are_______ different ways to display the five types of laser printer on a shelf.
Answer:
120 ways
Step-by-step explanation:
This is a pretty straightforward question. We are asked how many ways can 5 printers be displayed on one shelf. We use the formula of factorial in getting the number of ways, i.e
n! = n * (n-1) * ..... 1, in the question given, our n = 5, so if we plug it in, we get
n! = 5 * (5-1) * (4-1) * (3-1) * (2-1) * 1
n! = 5 * 4 * 3 * 2 * 1
n! = 120.
Thus, there are 120 different ways to display the five types of laser printer on a shelf.

The pH of stomach acid is 2.7. Which of the following is the closest to the hydrogen concentration?
Answer:
0.002M
Step-by-step explanation:
2.7= -log(H^+)
-2.7=log(H^+)
10^-2.7 M=H^+
0.0002M=H^+
The stomach has an acidic fluid that is an important part of the digestive juices. The pH of 2.7 in the stomach is close to a 0.002M concentration of hydrogen.
What is pH?pH measures the concentration of the hydronium and the hydrogen ions in the solution. pH is calculated as:
pH = -log (H⁺)
Here, pH = 2.7
Substituting values:
2.7 = -log (H⁺)
-2.7 = log (H⁺)
H⁺ = 10⁻²⁷ M
H⁺ = 0.0002M
Therefore, 0.002M is the concentration of hydrogen.

If the mFT 3x - 2 and the mFE = 5x + 1, Find x and mTE. (GT is median)
Please get back to me soon, I'll give Brainliest!
Answer:
x = 5
TE = 13
Step-by-step explanation:
Since GT is the median, then 2*(FT) = FE.
FE = 5x + 1
FT = 3x - 2
Therefore:
2*(3x - 2) = 5x + 1 (substitution)
6x - 4 = 5x + 1
Collect like terms
6x - 5x = 4 + 1
x = 5
TE = ½*(FE)
TE = ½*(5x + 1)
Plug in the value of x
TE = ½*(5(5) + 1)
TE = ½(25 + 1) = ½(26)
TE = 13
