Step-by-step explanation:
Using the trigonometric identities
tanx = [tex]\frac{sinx}{cosx}[/tex] , sin²x + cos²x = 1, secx = [tex]\frac{1}{cosx}[/tex]
Consider left side
tanAsinA + cosA
= [tex]\frac{sinA}{cosA}[/tex] × sinA + cosA
= [tex]\frac{sin^2A}{cosA}[/tex] + cosA
[tex]\frac{sin^2A+cos^2A}{cosA}[/tex]
= [tex]\frac{1}{cosA}[/tex]
= secA = right side , thus proven

Simplify by using the Distributive Property
4(4f-2g)
Answer:
the answer is 16f-8g
Answer:
16f - 8g
Step-by-step explanation:
You would multiply the terms in the middle by 4 so 4f*4 would be 16f since 4*4 is 16 and then 4*2g would be 8g since 4*2 is 8
f(x) = 3x + 2
g(x) = 2x^2 - 4x
h(x) = x^2 - x + 7
Find f[g(5)]
A. 92
B. 2
C. 30
D. 242
Answer:
A
Step-by-step explanation:
Evaluate g(5), then use the value obtained to evaluate f(x) , that is
g(5) = 2(5)² - 4(5) = 2(25) - 20 = 50 - 20 = 30, then
f(30) = 3(30) + 2 = 90 + 2 = 92

Carrie and nine of her friends go out to dinner. The total bill comes to $200. They decide to leave a 15% tip. Each person will contribute an equal amount to the total tip. What each person should contribute
Answer:
$3
Step-by-step explanation:
To find the value of the tip, multiply 200 by 15%.
200 x 15% = 30
Divide the tip by the number of people at the dinner (Carrie plus 9 friends = 10 people)
30 / 10 = 3
Each person should contribute $3 toward the tip.
Each person will contribute $23.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total Bill= $200
Tip= 15%
So, the amount of bill be paid after tip
= 200+ 200 x 15%
= 200+ 200 x 15/100
= 230
Now, each of them have to pay
= 230/ 10
= $23
Hence, Each of them paid $23.

The average winter temperature at the South Pole is -49 degrees Celsius. The coldest temperature recorded in Antarctica was 40.6 degrees Celsius colder than the average winter temperature at the South Pole. What was the coldest recorded temperature in Antarctica?
Answer:
The coldest temperature at Antarctica is -89.6 degrees celsius
Step-by-step explanation:
Here, we are interested in calculating the coldest temperature in Antarctica.
In the question, we are simply told that the coldest Antarctica temperature was 40.6 colder than the average winter temperature at the south pole.
The average winter temperature at south pole = -49 degree celsius
The coldest temperature is thus -49-40.6 = -89.6 degrees celsius
