The graph of the equation r= 5 sin 30 is which of the following?
A) Symmetrical about the horizontal axis
B) Symmetrical about the vertical axis
C) Symmetrical about the pole
D) Not symmetrical
The equation [tex]r=5\sin\left(\theta\right)[/tex] is a polar form
The graph of the equation is symmetrical about the horizontal axis
How to determine the true statement
The equation of the graph is given as:
[tex]r=5\sin\left(\theta\right)[/tex]
Next, we plot the graph of the function.
From the graph of the function (see attachment), we can see hat the graph of the function [tex]r=5\sin\left(\theta\right)[/tex] sits on the horizontal axis.
This means that the graph is symmetrical about the horizontal axis

A recipe uses 5 cups of milk to make 25 servings. If the same amount of milk is used for each serving, how many servings can be made from three quarts?
The total number of servings is given by the equation A = 60 servings
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of servings from 3 quarts be A
Now , the equation will be
The number of servings for 5 cups of milk = 25 servings
So , the number of servings for 1 cup = 25 / 5
The number of servings for 1 cup of milk = 5 servings
And , 1 quart = 2 pints
1 pint = 2 cups
So , 1 quart = 4 cups
And , 3 quarts = 12 cups
So , The number of servings for 3 quarts or 12 cups of milk = 12 x number of servings for 1 cup of milk
Substituting the values in the equation , we get
The number of servings for 3 quarts or 12 cups of milk A = 12 x 5
The number of servings for 3 quarts or 12 cups of milk A = 60 servings
Therefore , the value of A is 60 servings
Hence , the number of servings is 60

Read the excerpt from The Boy Who Harnessed the Wind by William Kamkwamba. I spent the day combing through the books while Mrs. Sikelo graded papers at her desk. Despite the variety of titles, I left that afternoon with books on geography, social studies, and basic spelling—the same textbooks my friends were studying in school. It was the end of the term, and my hope was to get caught up before classes started again. At home I planted a thick blue gum pole deep in the ground near the mango tree out front, then made my own hammock out of knotted maize sacks. For the next three weeks, I began a rigorous course in independent study, visiting the library in the mornings, and spending the afternoons reading in the shade. What idea does the excerpt help develop? The author is dedicated and studious. The author is confused and overwhelmed. The author is planting and caring for trees. The author checks out many books.

A person invests 8500 dollars in a bank. The bank pays 6% interest compounded semi-annually. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 15500 dollars?
The time required to get a total amount of $15,500.00 with compounded interest on a principal of $8,500.00 at an interest rate of 6% per year and compounded 2 times per year is 10.162 years (about 10 years 2 months)
Compound Interest AnalysisGiven Data
Principal P = $8,500Rate r = 6%Final Amount A = $15500Time t = 1 yearCalculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 6/100
r = 0.06 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(15,500.00/8,500.00) / ( 2 × [ln(1 + 0.06/2)] )
t = ln(15,500.00/8,500.00) / ( 2 × [ln(1 + 0.03)] )
t = 10.162 years

Can you help me find t value in this problem?
we have a maximum at t = 0, where the maximum is y = 30.
We have a minimum at t = -1 and t = 1, where the minimum is y = 20.
How to find the maximums and minimums?
These are given by the zeros of the first derivation.
In this case, the function is:
w(t) = 10t^4 - 20t^2 + 30.
The first derivation is:
w'(t) = 4*10t^3 - 2*20t
w'(t) = 40t^3 - 40t
The zeros are:
0 = 40t^3 - 40t
We can rewrite this as:
0 = t*(40t^2 - 40)
So one zero is at t = 0, the other two are given by:
0 = 40t^2 - 40
40/40 = t^2
±√1 = ±1 = t
So we have 3 roots:
t = -1, 0, 1
We can just evaluate the function in these 3 values to see which ones are maximums and minimums.
w(-1) = 10*(-1)^4 - 20*(-1)^2 + 30 = 10 - 20 + 30 = 20
w(0) = 10*0^4 - 20*0^2 + 30 = 30
w(1) = 10*(1)^4 - 20*(1)^2 + 30 = 20
So we have a maximum at x = 0, where the maximum is y = 30.
We have a minimum at x = -1 and x = 1, where the minimum is y = 20.
