Answers
Answer:
Part 1) [tex]c=21.9\ units[/tex]
Part 2) [tex]B=61.1\°[/tex]
Part 3) [tex]A=28.9\°[/tex]
Part 4) [tex]C=90\°[/tex]
Step-by-step explanation:
step 1
Find the length side c
Applying the Pythagoras Theorem
[tex]c^{2}=a^{2}+b^{2}[/tex]
substitute the given values
[tex]c^{2}=10.6^{2}+19.2^{2}[/tex]
[tex]c^{2}=481[/tex]
[tex]c=21.9\ units[/tex]
step 2
Fin the measure of angle B
we know that
In the right triangle
[tex]tan(B)=b/a[/tex]
substitute the given values
[tex]tan(B)=19.2/10.6[/tex]
[tex]B=arctan(19.2/10.6)=61.1\°[/tex]
step 3
Find the measure of angle A
we know that
The measure of interior angles in a triangle must be equal to 180 degrees
so
∠A+∠B+∠C=180°
Remember that in a right triangle the measure of angle C is 90 degrees
we have
[tex]B=61.1\°[/tex]
[tex]C=90\°[/tex]
substitute
[tex]A+61.1\°+90\°=180\°[/tex]
[tex]A=28.9\°[/tex]

A researcher determined the amount of ducks that were in a pond over a four-year time span. The results are shown in the table below.
Year 1, 2, 3, 4
Ducks 64, 78, 92. 106
Year Ducks
1 64
2 78
3 92
4 106
Select an equation that best models the amount of ducks (d) that will be in the pond during the nth year.
d= 64(1.22)^n-1
d=14n +64
d= 14n + 50
d + 50(1.14)^n-1
Answers
Answer:
Option C (d = 14n + 50).
Step-by-step explanation:
The observations for Year 1, 2, 3, and 4 are 64, 78, 92, and 106 respectively. It can be observed that the difference between second term and the first term is 78 - 64 = 14. This is also true for the third term and the second term. In fact, the difference between the terms is fixed. This means that the sequence is an arithmetic sequence, in which the difference between the terms is fixes for all the terms. The nth term in this case is defined as:
S = a + (n-1)*d; where S is the output at a given n, a is the first term, n is the position, and d is the common difference. In this question, S = ducks (d), a = 64, and d = 14. Therefore, plugging in the values in the above formula gives:
d = 64 + (n-1)*14.
d = 64 + 14n - 14.
d = 14n + 50.
Therefore, the model which best describes the amount of ducks that will be in the pond during the nth year is d = 14n + 50, i.e. Option C!!!
Answer: Third Option
[tex]a_n =14n+50[/tex]
Step-by-step explanation:
By subtracting consecutive terms from the number of ducks each year you will get a common difference of 144.
[tex]78-64 = 14\\92-78 = 14\\106-92 = 14[/tex]
This means that the data can be modeled by the equation of an arithmetic sequence
The arithmetic sequences have the following form:
[tex]a_n = a_1 + d(n-1)[/tex]
Where [tex]a_1[/tex] is the first term and d is the common difference between the consecutive terms.
So :
[tex]a_1 = 64[/tex]
[tex]d = 14[/tex]
Then the equation is:
[tex]a_n = 64 + 14(n-1)[/tex]
[tex]a_n = 64 + 14n-14[/tex]
[tex]a_n =14n+50[/tex]

2x^2+y^2=8xy find dy/dx
Answers
Answer:
2(x-2y)/(4x-y) = dy/dx
Step-by-step explanation:
2x^2+y^2=8xy
Take the derivative of each term, remembering that we take the 8xy as derivative by parts)
2 * 2x dx + *2y dy = 8 ( x dy + dx *y)
4x dx +2y dy = 8x dy + 8y dx
Subtract 2y dy from each side
4x dx +2y dy -4y dy = 8x dy - 2y dy + 8y dx
4x dx = 8x dy - 2y dy + 8y dx
Subtract 8y dx from each side
4x dx -8y dx = 8x dy - 2y dy + 8y dx-8y dx
4x dx -8y dx = 8x dy - 2y dy
(4x-8y) dx = (8x-2y) dy
Factor out a 4 from the left side and a 2 from the right side
4(x-2y) dx = 2( 4x-y) dy
Cancel a 2
2(x-2y) dx = ( 4x-y) dy
Divide each side by (4x-y)
2(x-2y)/(4x-y) dx = ( 4x-y)/(4x-y) dy
2(x-2y)/(4x-y) dx = dy
Divide by dx
2(x-2y)/(4x-y) dx/dx = dy/dx
2(x-2y)/(4x-y) = dy/dx

In the number 2010, the value represented by the digit 1 is what fraction of the value represented by the digit 2?
Answers
Answer:
Step-by-step explanation:
The two represents 2000
The one represents 10
The fraction you want is 10/2000 = 1/200 or 0.005
The value represented by the digit 1 in the number 2010 is 1/200 of the value represented by the digit 2. This is determined by comparing their place values, with 1 in the tens place and 2 in the thousands place.
To determine the value represented by the digit 1 in the number 2010, we need to understand place value.
→ The digit 1 is in the tens place, so its value is 10 (1 × 10).
→ The digit 2 is in the thousands place, so its value is 2000 (2 × 1000).
The fraction of the value represented by the digit 1 to the value represented by the digit 2 is calculated as follows:
→ Fraction = Value of digit 1 / Value of digit 2
= 10 / 2000
= 1/200
Therefore, the value represented by the digit 1 is 1/200 of the value represented by the digit 2 in the number 2010.

6. Solve the following equation for x. Show each step.
5x + 2 = 3x + 4(2x - 1)
Answers
Answer:
x=1
Step-by-step explanation:
5x + 2 = 3x + 4(2x - 1)
Distribute the 4
5x + 2 = 3x + 8x - 4
Combine like terms
5x + 2 = 11x - 4
Subtract 5x from each side
5x -5x + 2 = 11x - 5x - 4
2 = 6x-4
Add 4 to each side
2+4 = 6x-4+4
6 = 6x
Divide each side by 6
6/6 =6x/6
1= x
The value of x is 1 for equation 5x + 2 = 3x + 4(2x - 1).
A statement that affirms the equivalence of two expressions joined by the equals symbol "=" is known as an equation.
Given,
[tex]5x+2=3x+4(2x-1)\\[/tex]
[tex]5x+2=3x+8x-4[/tex]
On transposing like terms on one side of the equation.
[tex]5x-3x-8x=-4-2\\-6x=-6[/tex]

[tex]-6x\times(-1)=-6(-1)\\6x=6[/tex]
On dividing by 6 on both sides,

Answers
Answer:
-9-3/1-(-7)
Step-by-step explanation:
Answer:
The slope of given line = -3/2
Step-by-step explanation:
Points to remember
slope of the line with end points (x1, y1) and (x2, y2) is given by,
Slope = (y2 - y1)/(x2 - x1)
To find the slope of the line
Here (x1, y1) = (-7, 3) and (x2, y2) = (1, -9)
Slope = (y2 - y1)/(x2 - x1)
= (-9 - 3)/(1 - -7)
= (-12)/8
= -3/2
Therefore the slope of given line = -3/2

(SHOW WORK)
Answers
To find the cost of 4 ounces of pecans, we set up a proportion comparing the cost to weight, resulting in $2.25 after rounding to the nearest cent.
Explanation:To determine the cost of 4 ounces of pecans when a one-pound (16 ounces) canister costs $8.99, we set up a proportion where the cost is directly proportional to the weight.
The proportion is $8.99/16 ounces = $X/4 ounces, where X represents the cost of 4 ounces of pecans.
Multiplying both sides by 4 to solve for X gives us $X = (4 ounces × $8.99) / 16 ounces.
Simplifying this, we find that $X = $2.2475, which, when rounded to the nearest cent, gives us an answer of $2.25.
what is the range of y=log_8 x
Answers
The answer is:
Range: All the real numbers or (-∞,+∞)
Why?To solve the problem, we need to rewrite the variable "x" as "y" and the variable "y" as "x", and then, isolate "y". Then, we need to look if there is any restriction to the resulting value of "y".
We are given the function:
[tex]y=log_8(x)[/tex]
Now, rewriting we have:
[tex]x=log_8(y)[/tex]
Then, isolating we have:
[tex]8^{x} =8^{(log_8(y))}\\\\8^{x}=y[/tex]
Therefore, we can see that the resultant function is a quadratic or polynomial function, we need to remember that there is no restriction for this type of functions, it means that the range of the function is equal to the Real numbers where the values of "x" exist.
Hence, the answer is:
Range: All the real numbers or (-∞,+∞)

Two angles of a triangle have the same measure and the third one is 3 degrees greater than the measure of each of the other two. Find the measure of the LARGEST angle in the triangle.
The LARGEST angle has a measure of ___ degrees.
Answers
Answer:
62 DEGREES
Step-by-step explanation:
TWO ANGLES=2A
LARGEST ANGLE=A+3
2A+A+3=180
3A=180-3=177
A=177/3=59
LARGEST ANGLE=59+3=62
Answer:
The Largest Angle angle has a measure of 62 degrees.
Step-by-step explanation:
In triangle ABC, angle ABC equals to angle ACB.
and BAC is the largest angle.
Let angle measure of ABC and ACB angles be "x" degree.
then, measure of third angle i.e BAC will be "x + 3" degrees.
Since sum of all angles of any triangle is 180 degree.
so, first angle + second angle + third angle = 180
x + x + (x + 3) = 180
3x = 180 - 3
3x = 177
x = 59 degrees
So, First angle = 59 degree
Second angle = 59 degree
Third Angle = 62 degree.
The Largest Angle angle has a measure of 62 degrees.

1 -7 -27
So the quotient x-7 while the remainder is -27.
So [tex]\frac{x^2-12x+8}{x-5}=(x-7)+\frac{-27}{x-5}[/tex]
You could do long division if you prefer:

The monthly compounded interest rate of 0.14% of Unity Bank is a better plan.
Step-by-step explanation:
Step 1 : Write the formula for calculating a monthly compound interest rate and for calculating an annually compounded interest rate.
Monthly compound interest rate = P(1+r/n)^nxt
n=12 (number of months in a year)
t=1 (number of years)
Annually compound interest rate = P(1+r/n)^nxt
n=1 (because it is for 1 year only)
t=1 (number of years=1)
Step 2 : Lets assume that P is $100 in both banks and time is 1 year.
Step 3 : Lets substitute the values to find out which one is better.
Monthly compound interest rate = P(1+r/n)^nxt
Monthly compound interest rate = 100(1+0.14/12)^12x1
Monthly compound interest rate = 114.93
114.93 - 100 = $14.93 per month
14.93 x 12 = $179.16 for 12 months or 1 year
Annually compound interest rate = P(1+r/n)^nxt
Annually compound interest rate = 100(1+1.6/1)^1x1
Annually compound interest rate = 260
260-100 = $160 for 1 year
Therefore, the monthly compounded interest rate of 0.14% of Unity Bank is a better plan.

Answer:
The Unity Bank is offering a good plan.
Step-by-step explanation:
Unity Bank offers a monthly compounded interest rate of 0.14%
So, yearly rate will be = [tex]0.14\times12=1.68[/tex]% or 0.0168
Sunrise Banking offers 1.6% or 0.016 interest compounded annually.
Lets check an example with these two rates.
The compound interest formula is = [tex]A=P(1+r/n)^{nt}[/tex]
Lets take P = $1000 and t = 1 year
Case 1: when r = 1.68% and n = 12
Putting the values in formula we get
A = [tex]1000(1+0.0168/12)^{12}[/tex]
= [tex]1000(1.0014)^{12}[/tex]
A = $1016.92
Case 2: when r = 1.6% and n = 1
Putting the values in formula we get
A = [tex]1000(1+0.016/1)^{1}[/tex]
= [tex]1000(1.016)^{1}[/tex]
A = $1016.00
So, we can see that the first case gives more return than second one.
Therefore, the Unity Bank is offering a good plan.
