In quadrant II, the standard position angle is found by subtracting the reference angle from 180°.
180° -68° = 112°
__
In quadrant IV, the standard position angle is found by subtracting the reference angle from 360°.
360° -75° = 285°
__
In quadrant III, the standard position angle is found by adding 180° to the reference angle.
180° +22° = 202°

Answers
ANSWER
c = 1/2
EXPLANATION
We want to simplify:
19 - 4c = 17
To do this, we first colect like terms:
19 - 17 = 4c
=> 2 = 4c
Now, divide through by 4:
4c / 4 = 2 / 4
c = 1/2
That is the answer.
8. The first three terms of a geometric sequence are ( x-6), 3x, and y. If the common ratio is 6, then the value of y is.
Answers
Answer:
The value of y is 216
(and the value of x is 12)
Step-by-step explanation:
The general formula for a geometric sequence is,
\(a_n = a_1(r)^{n-1}\)
Where n represents the nth term, a_1 is the first term and r is the common ratio,
we see that,
r = 6,
the first term is,
a_1 = (x-6)
the 2nd term is,
a_2 = 3x,
the 3rd term is,
a_3 = y, finding y,
first we find x, using the above given formula we have,
\(a_2 = a_1(6)^{2-1}\\3x = (x-6)(6^1)\\3x = 6x -36\\36 = 6x - 3x\\36 = 3x\\x=36/3\\x=12\)
x = 12,
Now, for y we can use the relation between a_3 and a_2,
\(a_3 = a_1(6)^{3-1}\\y = (x-6)(6)^2\\y = (12-6)(6^2)\\y = 6(6^2)\\y = 6^3\\y = 216\)
y = 216

Answers
The order of operations (PEMDAS) states that we should perform multiplication and division before addition and subtraction. Using this order, we get:
244 - (33456 / 3456) * 345 + 13.55 - 2
= 244 - 97.02 * 345 + 13.55 - 2
= 244 - 33494.1 + 13.55 - 2
= -33238.55
Therefore, 244-33456/3456*345+13.55-2 = -33238.55.

The sum of two consecutive even numbers is 30. How can you solve for the 2 numbers?
Answers
Answer:
14 and 16.
Step-by-step explanation:
We know that two consecutive even numbers is 30.
Let's let n be any number.
Then the first even number must be 2n.
This is because n can be any number, either even or odd. However, if we multiply it by 2, this ensures that 2n is even. Remember that any number multiplied by 2 yields an even number.
Therefore, the consecutive even number will be (2n+2). Not (2n+1), because that gives an odd number.
We know that they sum to 30. So, we can write the following equation.
\((2n)+(2n+2)=30\)
And we solve from there:
\(4n+2=30\\\Rightarrow4n=28\\\Rightarrow n=7\)
So, the value of n is 7.
Therefore, the first even number is 7(2)=14.
And the consecutive even number is 16.

Last year, Bob had $10,000 to invest. He invested some of it in an account that paid 5% simple interest per year, and he invested the rest in an account thatpaid 6% simple interest per year. After one year, he received a total of $540 in interest. How much did he invest in each account?
Answers
Answer
To know how much Bob invested in the account that paid 5%, we shall use the relation below
\(\frac{5}{100}x+\frac{6}{100}(10000-x)=540\)Where x is the amount invested in an account that paid 5% simple interest and (10000 - x) represents, the amount invested in an account that paid 6% simple interest.
\(\begin{gathered} \Rightarrow0.05x+0.06(10000-x)=540 \\ 0.05x+600-0.06x=540 \\ 0.05x-0.06x=540-600 \\ -0.01x=-60 \\ x=\frac{60}{0.01} \\ x=6000 \end{gathered}\)Therefore, $6,000 is the amount invested in the account that paid 5% simple interest
Now, the amount invested in an account that paid 6% simple interest would be
\(\begin{gathered} =10000-6000 \\ =4000 \end{gathered}\)∴ $4,000 is invested in an account that paid 6% simple interest.

The value of the given functions is g(f(2)) = g(10) = 5.
What is a function?
Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships;
We are given that;
f(x) = x² + 3x
g(x)=x-5
Now,
To find g(f(2)), we first need to evaluate f(2), and then use the result as the input for g.
First, we evaluate f(2) by substituting 2 for x in the expression for f(x):
f(2) = 2² + 3(2) = 4 + 6 = 10
Now we use this result as the input for g:
g(f(2)) = g(10)
Finally, we evaluate g(10) by substituting 10 for x in the expression for g(x):
g(10) = 10 - 5 = 5
Therefore, the answer of the function will be g(f(2)) = g(10) = 5.

In certain deep parts of oceans, the pressure of sea water,P, in pounds per square foot, at a depth of d feet below the surface, is given by the following equation P=14+ 4d/9
If a scientific team uses special equipment to measure the pressure under water and find it to be 306 pounds per square foot, at what depth is the team making their measurements?
Answers
It is important to note that this equation assumes a constant density of seawater, which is not always the case in the deep ocean. In addition, the pressure at a given depth can vary depending on factors such as temperature and salinity. This equation should be used with caution and in conjunction with other measurements and data analysis techniques.
The given equation for pressure in pounds per square foot at a depth of d feet is P = 14 + 4d/9. We are given that the pressure measured by the scientific team is 306 pounds per square foot. To find the depth at which this pressure is measured, we need to solve the equation for d.
Substituting P = 306 in the equation, we get:
306 = 14 + 4d/9
Multiplying both sides by 9, we get:
2754 = 126 + 4d
Subtracting 126 from both sides, we get:
2628 = 4d
Dividing both sides by 4, we get:
d = 657 feet
The scientific team is measuring the pressure at a depth of 657 feet below the surface of the ocean.

What is the value of the expression shown below 14 1/3 - 6 5/8
Answers
Answer:
the value of the expression 14 1/3 - 6 5/8 is 185/24.
Step-by-step explanation:
To solve this problem, you can convert both mixed numbers to improper fractions, then subtract the fractions and simplify the result. Here are the steps:
1. Convert 14 1/3 to an improper fraction:
14 1/3 = (14 x 3 + 1) / 3 = 43 / 3
2. Convert 6 5/8 to an improper fraction:
6 5/8 = (6 x 8 + 5) / 8 = 53 / 8
3. Subtract the fractions:
43 / 3 - 53 / 8 = (43 x 8 - 53 x 3) / (3 x 8) = (344 - 159) / 24 = 185 / 24
So the value of the expression 14 1/3 - 6 5/8 is 185/24.

Brandon invests $5800 in two different accounts. The first account paid 3 %, the second account paid 8 % in interest. At the end of the first year he had earned $229 in interest. How much was in each account?
$ ___ at 3 %
$ ____ at 8 %
Answers
Interest is a fee charged by a lender to a borrower for the use of money or credit, usually expressed as a percentage of the amount borrowed or invested over a period of time. Brandon invested $\(4700\) at 3% interest and $\(1100\) at \(8\)% interest. The total interest earned after one year is $229
How much was in each account?
Let x be the amount invested in the first account that pays 3% interest, and let y be the amount invested in the second account that pays 8% interest. Since the total amount invested is $5800, we have:
\(x + y = 5800\)
The amount of interest earned on the first account is 0.03x, and the amount of interest earned on the second account is 0.08y. Since the total interest earned after one year is $229, we have:
\(0.03x + 0.08y = 229\)
We now have two equations with two unknowns:
\(x + y = 5800\)
\(0.03x + 0.08y = 229\)
We can solve for x and y by using elimination or substitution method. Here, we will use the substitution method.
Solve the first equation for x:
\(x = 5800 - y\)
Substitute this expression for x into the second equation and solve for y:
\(0.03(5800 - y) + 0.08y = 229\)
\(174 - 0.03y + 0.08y = 229\)
\(0.05y = 55\)
\(y = 1100\)
Now substitute this value of y into either equation to solve for x:
\(x + 1100 = 5800\)
\(x = 4700\)
Therefore, Brandon invested $\(4700\) at 3% interest and $\(1100\) at \(8\)% interest.

Answer: -30/29
Step-by-step explanation: Let's solve your equation step-by-step.
(5)(2)+29x+20=0
Step 1: Simplify both sides of the equation.
(5)(2)+29x+20=0
10+29x+20=0
(29x)+(10+20)=0(Combine Like Terms)
29x+30=0
29x+30=0
Step 2: Subtract 30 from both sides.
29x+30−30=0−30
29x=−30
Step 3: Divide both sides by 29.
29x/29=-30/29
