tan(x)/sec(x)=sin(x)
Answers
Answer:
(identity has been verified)
Step-by-step explanation:
Verify the following identity:
tan(x)/sec(x) = sin(x)
Hint: | Eliminate the denominator on the left hand side.
Multiply both sides by sec(x):
tan(x) = ^?sec(x) sin(x)
Hint: | Express both sides in terms of sine and cosine.
Write secant as 1/cosine and tangent as sine/cosine:
sin(x)/cos(x) = ^?1/cos(x) sin(x)
Hint: | Come to a conclusion.
The left hand side and right hand side are identical:

Step-by-step explanation:
tangent = opposite / adjacent
tan 35° = h / 25
multiply both sides by 25
h = 25 (tan 35°)
tan 35° = 0.70 (from your calculator)
h = 25 (0.70)
h = 17.51 ft.
Which of the answer choices describes Monica's budget?
Monica's Budget

Transportation $78 Annual Expenses
Food $190 Car Insurance $945
Entertainment $30 Books $280
It is in deficit.
It is balanced.
It is in surplus.
HELP ASAP!!!!!!!!!!!!THIS IS QUESTION 43
Answers
Answer:
It is in deficit
Step-by-step explanation:
If you take her income (655) and subtract all of the expenses, including adding the annual expenses together and dividing them by 12 months, the result would be negative.
It is in deficit describes the Monica's budget.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We can calculate Monica's total fixed expenses as:
Rent + Electric + Transportation + Food + Entertainment = $200 + $45 + $78 + $190 + $30 = $543
Her annual expenses are:
Car Insurance + Books = $945 + $280 = $1225
Adding her fixed and annual expenses gives:
$543 + $1225 = $1768
Since her income is only $655, her expenses exceed her income and she is operating at a deficit. Therefore, the answer is: It is in deficit.
Hence, It is in deficit describes the Monica's budget.

Step-by-step explanation:
Problem:
You deposit $500 into a bank account and received $55 simple interest after 5 years. What had been the interest rate?
Result:
The interest rate was 2.2% per year.
Explanation:
Find interest rate by using the formula I = P*i*t , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years. In this example I = $55, P = $500 and t = 5 years, so
i = 55/500*5
i=0.022 = 2.2% per year
