5. Use the angle addition formula to find the expression for cos (a+b).
Answer:
Step-by-step explanation:
Trigonometric identities are used to show the equality of expressions involving trigonometric functions. These trigonometric functions are the sine, the cosine, and the tangent as well as their respective reciprocals which are cosecant, the secant, and the cotangent,
Some trigonometric identities are:
tanθ = sinθ / cosθ; secθ = 1 / cosθ; cosecθ = 1 / sinθ; cotθ = 1 / tanθ = cosθ / sinθ
The angle addition formula for cos is given as:
cos(α + β) = cosαcosβ - sinαsinβ
Therefore:
cos(a + b) = cosacosb - sinasinb

The shadow of the tree is 40 feet long. A yard-stick placed next to the tree casts a 6 foot shadow. How tall is the tree?
Answer:
pretty sure the tree's 20 feet
According to proportion if a tree casts a shadow of 40 feet it;s height is 20 feet.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
We know 1 yard is 3 feet.
Given, The shadow of the tree is 40 feet long. A yardstick placed next to the tree casts a 6-foot shadow and assuming the height of the tree to be x.
∴ x : 40 : : 3 : 6.
x/40 = 3/6.
6x = 120.
x = 20 feet.

Lexi say that -68 feet is a greater depth than- 75 feet, since-68>-75. Is Lexi correct? Explain
Answer:
No
Step-by-step explanation:
When working with negative numbers in terms of depth, greater depth are depicted by values as we move farther to the left of the number line.
With this in mind, - 75 feets is farther to the left of the number line and as such represents a greater depth value Than - 68 feets
Therefore, when expressing depth or elevation distances, the values should be iewwd in absolute terms. Then |75| > |68|. While bearing in mind that depth is downward and thus negative

Step-by-step explanation:
Kadeem is making two drawings of an oak leaf. The dimensions of the first drawing will be 1/3 the dimensions of the leaf. The dimensions of the second drawing will be 2 1/2 the dimensions of the leaf. If the oak leaf is 5 1/2 inches, will the length of each drawing be equal to, greater then, or less than 5 1/2 inches?
Answer: See explanation
Step-by-step explanation:
The dimensions of the first drawing will be 1/3 the dimensions of the leaf and the dimension of the oak leaf is 5 1/2 inches. Therefore, the dimensions of the 1st leaf:
= 1/3 × 5 1/2
= 1/3 × 11/2
= 11/6
= 1 5/6 inches
This is less than 5 1/2 inches
The dimensions of the second drawing will be 2 1/2 the dimensions of the leaf. This will be:
= 2 1/2 × 5 1/2
= 5/2 × 11/2
= 55/4
= 13 3/4 inches
Thus is greater than 5 1/2 inches

What is the total cost of a $95.00 item with a sales tax of 6%
Answer: $100.70
Step-by-step explanation: 6% is equal to 0.06, so you can add multiply the price of the item by 1.06 because that is the base cost plus the tax. Then you get $100.70.
Answer:
100.70
Step-by-step explanation:
95.00*6%
95.00*.06=5.70
95.00+5.70=100.70
How does changing the slope effect the parent function? How does changing the y-intercept effect the parent function?
Answer/Explanation:
When you change the slope, it will affect the steepness of the graph/line.
When you change the y-intercept (b) it will affect where the graph crosses the y axis.
-increasing the y-intercept will make the graph move up and
decreasing will make the y-intercept go down.
Solve for the value of the variable: 7x+ 10 = 4x + 16
Enter the answer
Step-by-step explanation:
7x + 10 = 4x + 16
3x + 10 = 16 (subtract 4x on both sides)
3x = 6 (subtract 10 on both sides)
x = 2 (divide 3 on both sides)

The population of a town was 25000 in the 2000 census and and 30000 in 2010 census. By what percent did the population increase
Answer: This means that the population increased a 20% between the year 2000 and the year 2010.
Step-by-step explanation:
In this case, we have that 25,000 is the 100%.
Now we want to know which percentage represents 30,000
Let's suppose that the percentage is X.
Then we can have a system of equations:
30,000 = X
25,000 = 100%
To find the value of X, we can take the quotient of these two equations:
30,000/25,000 = X/100%
(30,00/25,000)*100% = X = 120%
Then in the 2000 we had a 100%, and in the 2010 there was a 120%.
The difference is:
120% - 100% = 20%
This means that the population increased a 20% between the year 2000 and the year 2010.

Is your grade level (9th, 10th, etc.) independent of your height? Why or why not? Type your answer below.
Hey there!
The answer is yes, because it does not depend on your height, because you can be any height in any grade (well, maybe not ANY height, because you can't be, like, 100 feet, or 1 inch, but you get the point...).
