Which trigonometric function would you use to find “h”, the height of the tree?
Answer: C
Answer:
C
Step-by-step explanation:
Sine: Opposite / Hypotenuse
Cosine: Adjacent / Hypotenuse
Tangent: Opposite / Adjacent
75 = The adjacent of 40
H = The opposite of 40
Tan40 = 75 / h
H = 75Tan40
H ≈ 62.93
The trigonometric function which will be used to determine the height of the tree when the base is 75 ft. is tan(40)
What is trigonometric function?The trigonometric function are the ratio of the sides of the right angled triangle. The functions are sine, cos, tan , cot, cosecant, secant.
How to find the height of the tree?We can easily see that the base is 75 ft. and the height of the tree is h So the height of the tree can be found with the help of tangent function.
tan(40)=h/75
0.84=h/75
h=63 ft.
Hence the height of the tree is 63 ft.

The height, h, of a plant (in inches) w weeks since it was planted is represented by the equations h=3w+3. How many weeks will it takes the plant to reach one foot.
Answer: 3 weeks
Step-by-step explanation:
We have to note firstly that 12 inches = 1 foot.
The equation given to represent the height in the question, h = 3w + 3.
The number of weeks that it will take the plant to reach one foot will then be:
h = 3w + 3
12 = 3w + 3
3w = 12 - 3
3w = 9
w = 9/3
w = 3
It'll take 3 weeks

Answer:
84.834 in
Step-by-step explanation:
Given data
Diameter of pool= 25 ft
Width of side walk= 2ft
Hence the diameter of the pool and the sidewalk combined= 25+2= 27ft
The radius of the pool and the sidewalk combined= 27/2= 13.5ft
Circumference= 2πr
Circumference= 2*3.142*13.5

The age of trees in a forest is known to be approximately normal with an average age of 40 years and a standard deviation of 10 years. About ____ of the trees have ages between 10 years and 70 years.
Answer:
Not 95%
Step-by-step explanation:
The normal distribution is also known as the Gaussian distribution. About 99.7% of the trees have ages between 10 years and 70 years.
What is Normal Distribution?The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Given that the age of the tree is normally distributed. Also, the following details are known,
Standard Deviation, σ = 10 years
Mean, μ = 40
Now, the z-score and the p-values for the value of 70 and 10 can be written as,
Z = (X-μ)/σ
Z = (70 - 40)/10
Z = 3
The p-value for z-score of 3 is 0.9987.
Z = (X-μ)/σ
Z = (10 - 40)/10
Z = -3
The p-value for z-score of -3 is 0.0013.
Further, the percentage of the trees have ages between 10 years and 70 years is,
Percentage = 0.9987 - 0.0013
= 0.9974
= 99.7%
Hence, About 99.7% of the trees have ages between 10 years and 70 years.

Round 1 of a tennis tournament starts with 64 players. After each round, half of the players have lost and are eliminated from the tournament. Therefore, in round 2 there are 32 and in round 3 there are 16 players and so on. Can this relationship be modeled by a linear function? Provide evidence to support your claim.
Answer:
It can not be modeled by a linear function
Step-by-step explanation:
The given parameters can be represented as:
[tex](x_1,y_1) = (1,64)[/tex]
[tex](x_2,y_2) = (2,32)[/tex]
[tex](x_3,y_3) = (3,16)[/tex]
Where: x = rounds and y = players
Required:
Determine if it can be represented by a linear function
To do this, we simply calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
and
[tex]m = \frac{y_3 - y_2}{x_3 - x_2}[/tex]
Using: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex], we have:
[tex]m = \frac{32 - 64}{2 - 1}[/tex]
[tex]m = \frac{-32}{ 1}[/tex]
[tex]m = -32[/tex]
Using [tex]m = \frac{y_3 - y_2}{x_3 - x_2}[/tex], we have:
[tex]m = \frac{16 - 32}{3 - 2}[/tex]
[tex]m = \frac{-16}{1}[/tex]
[tex]m = -16[/tex]
Since both slopes are not the same, the relationship be modeled by a linear function

Ms. Rivera runs a house cleaning business. To save money, she bought a 1-gallon container of concentrated cleaner. She mixed the cleaner with 10 gallons of water. Then, she filled as many 1-pint spray bottles as she could. How many spray bottles did she fill?
Answer:
88 bottles
Step-by-step explanation:
Given
[tex]Cleaner =1\ gallon[/tex]
[tex]Water =10\ gallon[/tex]
Required
Determine the number of 1-pint spray bottles used
First, we get the total gallons of the cleaner and water.
[tex]Total = Cleaner + Water[/tex]
[tex]Total = 1\ gallon + 10\ gallon[/tex]
[tex]Total = 11\ gallon[/tex]
Convert to pints:
[tex]Total = 11 * 8\ pints[/tex]
[tex]Total = 88\ pints[/tex]
To get the number of spray bottles, we divide 88 pints by the size of the pint bottle.
[tex]Number = \frac{88\ pints}{1\ pint}[/tex]
[tex]Number = \frac{88}{1}[/tex]
[tex]Number = 88[/tex]

Step-by-step explanation:
1. Approach
Probability is a way of predicting a future outcome based on given data. In essence, the formula for finding the probability is, [tex]\frac{desired\ outcomes}{total\ outcomes}[/tex].
It is given that
- (63) paid with cash
- (22) paid with a debit card
- (13) paid with a credit card
First, add all of these numbers up to find the total number of customers. Then set up the probability, finally, simplify the fraction by diving both the numerator and denominator by a common factor.
2. Find the total number of customers
Add up all of the given customers, regardless of their payment type.;
[tex](cash)+(credit)+(debit)\\\\= 63 + 22 + 13\\\\= 98[/tex]
(98) total customers.
3. Find the probability
Now set up the probability, remember, the formula for finding the probability is,
[tex]\frac{desired\ outcomes}{total\ outcomes}[/tex]
The desired outcome is the number of customers who pay with cash = (63)
The total outcome is the number of customers who when to the business; (98)
Substitute in the numbers and simplify,
