Step-by-step explanation:
The Symmetric Property of Congruence lets you say that if ∠H ≅ ∠K, then ∠K ≅ ∠H.
We know that Symmetric property of Congruence states that if:
∠A≅∠B,then ∠B≅∠A
Therefore according to the property,the missing angle in the statement is ∠K....
Given f(x) = V6x and g(x) =
-6
Which value is in the domain of fºg?
Click on the correct answer.
Answer:
8 is the only one that will work
Step-by-step explanation:
(f o g)(x)=f(g(x)).
So this means the x will first be plug into g.
So let's check your choices.
g(6)=1/(6-6)=1/0 so 6 is not in the domain of g which means it isn't in the domain of (f o g).
g(8)=1/(8-6)=1/2 so this is a number so 8 is in the domain of g,
Let's check if 1/2 is in the domain of f.
f(1/2)=sqrt(6*1/2)=sqrt(3) so this is a number so since 1/2 is in the domain of f then 8 is in the domain of (f o g).
g(4)=1/(4-6)=1/(-2)=-1/2 so 4 is in the domain of g,
f(-1/2)=sqrt(6*-1/2)=sqrt(-3) so this is a problem because you can't square root negative numbers so -1/2 isn't in the domain of f, and therefore 4 isn't in the domain of (f o g).
g(2)=1/(2-6)=1/-4=-1/4 so 2 is in the domain of g.
f(-1/4)=sqrt(6*-1/4)=sqrt(-3/2) so again this is a problem because we can't square root negative numbers so -1/4 isn't in the domain of f, and therefore 2 isn't in the domain of (f o g).
Say you have $14,000 to invest into an investment account. You can either invest your money into an account with a 7% annual interest rate which is compounded quarterly, or an account with a 6.8% annual interest rate which is compounded monthly, which should you choose for a 15-year investment?
Answer:
You should choose an account with a 7% annual interest rate which is compounded quarterly
Step-by-step explanation:
we know that
The compound interest formula is equal to
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
part 1)
we have
[tex]t=15\ years\\ P=\$14,000\\ r=0.07\\n=4[/tex]
substitute in the formula above
[tex]A=14,000(1+\frac{0.07}{4})^{4*15}[/tex]
[tex]A=14,000(1.0175)^{60}[/tex]
[tex]A=\$39,645.43[/tex]
part 2)
we have
[tex]t=15\ years\\ P=\$14,000\\ r=0.068\\n=12[/tex]
substitute in the formula above
[tex]A=14,000(1+\frac{0.068}{12})^{12*15}[/tex]
[tex]A=14,000(1.0057)^{180}[/tex]
[tex]A=\$38,713.11[/tex]
Select which form to use when you know the slope of the line and one of the points on the line.
a horizontal line
C slope-intercept for
b. vertical line
d. point-slope form
Answer:
d
Step-by-step explanation:
Definitely choose the point-slope form y - k = m(x - h) (Answer d)
Final answer:
To write the equation of a line when you have the slope and a single point on the line, the D) point-slope form is the most suitable formula to use.
Explanation:
When you know the slope of a line and a point on the line, the best form to use is the point-slope form. The point-slope formula is expressed as y - y1 = m(x - x1), where m is the slope and (x1, y1) is the known point. This formula allows you to plug in the slope and the coordinates of the point directly to form the equation of the line.
The slope-intercept form y = mx + b is used when you know the slope and the y-intercept, while the point-slope form is specifically designed to formulate an equation given a point and the slope of the line. A horizontal line, which has a slope of zero, nor a vertical line, which has an undefined slope, would not apply to this particular situation.
How many solutions does y=5-2x 4x+2y = 10
Answer:
Infinitely Many
Step-by-step explanation:
Equations:
y = 5 - 2x
4x + 2y = 10
There are multiple ways to solve this, but I'm going to use substitution.
Since y = 5 - 2x, I will input this y value into the second equation.
4x + 2(5 - 2x) = 10
From here, it's simple algebra.
4x + 10 - 4x = 10
- 10 - 10
4x - 4x = 0
0x = 0
Because we essentially have the solution 0 = 0, this means that the system has an infinite amount of solutions.
Why?
Well, they're the same line. (Put both into slope intercept form.)
y = 5 - 2x OR y = -2x + 5
4x + 2y = 10
2y = -4x +10
= y = -2x + 5
Answer:
INFINITE SOLUTIONS.
Step-by-step explanation:
y = 5 - 2x
4x + 2y = 10
From the first equation:
2x + y = 5 Multiply this equation by -2:
-4x - 2y = -10
Adding the above to the second equation:
0 = 0 So the 2 equations are identical and there are Infinite SOLUTIONS>

What is sin -1 (1/2) if the terminal side of 0 is located in quadrant 1
Answer:
sin^-1 (1/2) = 30°
Step-by-step explanation:
* Lets explain how to find the trigonometry functions from the unit circle
- The unit circle is the circle whose radius is 1 unit
- It intersects the four axes at:
# Positive part of x-axis at (1 , 0) and negative part at (-1 , 0)
# Positive part of y-axis at (0 , 1) and negative part at (0 , -1)
- The terminal of any angle intersect it at point (x , y) where x² + y² = 1
- If The angle between the terminal side and the x-axis is Ф , then
# The adjacent side of Ф = x
# The opposite side of the angle Ф = y
- In the problem the terminal side lies in the first quadrant
∴ all the trigonometry functions are positive
∵ sin Ф = opposite/hypotenuse
∵ The opposite = 1/2 and the hypotenuse is the terminal side = 1
∴ sin Ф = 1/2 ÷ 1 = 1/2
- To find Ф use the inverse function sin^-1 Ф
∵ sin Ф = 1/2
∴ Ф = sin^-1 (1/2)
∴ Ф = 30°
* sin^-1 (1/2) = 30°
2. A line passes through (1.-5) and (-3, 7). Write an equation for the line in point-slope form.
Rewrite the equation in slope-intercept form.
Answer:
See below.
Step-by-stepexplanation:
The slope = rise/run
= (7- -5)/(-3-1)
= 12/-4
= -3
In point slope form:
y - y1 = -3(x - x1)
y - (-5) = -3(x - 1)
y + 5 = -3(x - 1) <--------- Point slope form.
y + 5 = -3x + 3
y = -3x - 2. <----------Slope-intercept form.
Answer:
y = -3x - 2
Step-by-step explanation:
If a line passes through (1.-5) and (-3, 7), the appropriate equation for the line in point-slope form is, y = -3x - 2.
A gem is cut in a kite shape. It is 6.2 millimeters wide at its widest point & 5 millimeters long. What is the area?
Answer: [tex]15.5\ mm^2[/tex]
Step-by-step explanation:
You can calculate the area of a kite with the following formula:
[tex]A=\frac{d_1d_2 }{2}[/tex]
Where [tex]d_1[/tex] is the length of a diagonal and [tex]d_2[/tex] is the length of the other diagonal.
In this case, you can identify that:
[tex]d_1=6.2\ mm\\d_2=5\ mm[/tex]
Therefore, the final step is to substitute the values into the formula.
Then, the area is:
[tex]A=\frac{(6.2\ mm)(5\ mm)}{2}\\\\A=15.5\ mm^2[/tex]
What is Y=3/4+2 graphed
Answer:
I don't possess a graph so I'll teach it to you.
Step-by-step explanation:
In a coordinate plane with 4 quadrants, the formula for this equation is SLOPE. This is fairly a very easy topic to learn about. The formula is y = mx + b.
So I assume you forgot to put the "x" after the 3/4.
Anyway, to answer this the "2" in bthe equation is the y-intercept. So the X-coordinate will ALWAYS be ZERO! O basically you plot at (0,2).
Next, you grab the slope. To get it you must use the RISE OVER RUN technique. You rise 3 UP and since it's a POSITIVE SLOPE, 3/4, NOT -3/4, you RUN 4 units to the RIGHT, which gives you (5,4), I believe. And you keep doing that until the graph is finished. And if you want to go backwards from (0,2), you make the RISE AND RUN, NEGATIVE. It's very simple. In the end you should get a line like "/" on your graph which means it's a POSITIVE SLOPE. If it's "\", IT'S A NEGATIVE SLOPE.

Step-by-step explanation:
m∠3 + m∠4 = 180°
TRUE - they are supplementary angles
m∠2 + m∠4 + m∠6 = 180°
TRUE - measureas of angles in a triangle add up to 180°
m∠2 + m∠4 = m∠5
TRUE, because
m∠2 + m∠4 + m∠6 = 180° and m∠6 + m∠5 = 180°
therefore m∠2 + m∠4 + m∠6 = m∠6 + m∠5 subtract m∠6 from both sides
m∠2 + m∠4 = m∠5
m∠1 + m∠2 = 90°
FALSE, because m∠1 + m∠2 = 180°
m∠4 + m∠6 = m∠2
FALSE, because
m∠4 + m∠6 + m∠2 = 180° subtract m∠2 from both sides
m∠4 + m∠6 = 180° - m∠2
m∠2 + m∠6 = m∠5
FALSE, because
m∠5 + m∠6 = 180° subtract m∠5 from both sides
m∠6 = 180° - m∠5 add m∠2 to both sides
m∠2 + m∠6 = 180° - m∠5 + m∠2
Bethany wrote the equation x+(x+2)+(x+4)=91 when she was told that the sum of three consecutive odd integers had a sum of 91. Which statement about her equation is true?
A) Bethany is correct because consecutive odd integers will each have a difference of two.
B) Bethany is correct because there are three xs in the equation and three is an odd number so it represents the sum of odd numbers.
C) Bethany is incorrect because 2 and 4 are even numbers, she should use 1 and 3 in their place.
D) Bethany is incorrect because consecutive integers always increase by 1 each time, not by 2.
Answer:
Bethany is correct because consecutive odd integers will each have a difference of two.
For example: [1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21...] All those are odd numbers, and have a difference of two.
So every time time we make 'x' an odd number in Bethany's equation, we will get three consecutive numbers.
For example, if 'x' equals '1', then we will get the three consecutive numbers 1, 3 and 5.
If 'x' equals 7, then we will get the three consecutive numbers 7, 9 and 11.
Answer:
A.) Bethany is correct because consecutive odd integers will each have a difference of two
Step-by-step explanation:
The sum of 3 consecutive odd integers is 91. Let the first odd integer is x. The next odd integer will be obtained by adding 2 in x i.e. (x + 2). The third odd integer will be obtained by adding 2 in the second odd integer i.e. (x + 2) + 2 = x + 4
After the information stated we can conclude that:
The 3 odd integers will be:
x , (x+2) and (x+4)
Their sum is given to be 91. So we can write:
x + (x+2) + (x+4) = 91
Hence, we can conclude that: Bethany is correct because consecutive odd integers will each have a difference of two.
Write the following inequality in slope-intercept form.
−6x + 3y ≥ −45
So, the inequality in slope-intercept form is [tex]\( y \geq 2x - 15 \).[/tex]
To write the given inequality in slope-intercept form [tex](y = mx + b)[/tex], let's first isolate the y term:
[tex]-6x + 3y \geq -45[/tex]
Add 6x to both sides:
[tex]3y \geq 6x - 45[/tex]
Now, divide both sides by 3:
[tex]y \geq 2x - 15[/tex]
[tex]\[\begin{align*}\frac{3y}{3} & \geq \frac{6x}{3} - \frac{45}{3} \\y & \geq 2x - 15\end{align*}\][/tex]

n a concert band, the probability that a member is in the brass section is 0.50. The probability that a member plays trombone, given that he or she is in the brass section, is 0.36. What is the probability that a randomly selected band member is in the brass section and plays trumpet?
A) 0.50
B) 0.72
C)0.14
D)0.18
Answer:
The correct option is D
Step-by-step explanation:
To find the solution of this problem firstly we will find the probability that some one is in the brass section and play trombone.
We will multiply the probability that a member is in the brass section which is 0.50 with the probability that a member plays trombone, given that he or she is in the brass section which is 0.36
= 0.50 * 0.36
=0.18
Therefore the probability that a randomly selected band member is in the brass section and plays trumpet is 0.18
Thus the correct option is D....

Both equations start with y =
Set both equations equal to each other and solve for x first:
1/3x-4 = -7/3x +4
Add 7/3x to both sides:
8/3x - 4 = 4
Add 4 to each side:
8/3x = 8
Divide both sides by 8/3
x = 3
Now you have the value of x, replace x in the equation to solve for y:
y = 1/3(3) -4 = 1-4 = -3
y = -7/3(3) +4 = -7+4 = -3
y = -3
X = 3 and y = -3
Wingspans of adult herons have approximate normal distribution with mean 125 cm and standard
deviation 12 cm. What proportion of herons have wingspan of exactly 140 cm?
Answer:
0.1056
Step-by-step explanation:
Given from the question;
Mean=125cm
Standard deviation =12cm
You should find the z* value from mean and standard deviation
The formula to apply is;
z=(wingspan in question - mean)÷standard deviation
[tex]z=\frac{140-125}{12} =\frac{15}{12} =1.25[/tex]
Using the Z score table read the value of proportion that corresponds to 1.25
From the table, the proportion is 0.1056

Cos y/ 1-sin y= 1+sin y/cos y. Verify the identity. Show All Steps!
Answer:
When proving identities, the answer is in the explanation.
Step-by-step explanation:
[tex]\frac{\cos(y)}{1-\sin(y)}[/tex]
I have two terms in this denominator here.
I also know that [tex]1-\sin^2(\theta)=\cos^2(theta)[/tex] by Pythagorean Identity.
So I don't know how comfortable you are with multiplying this denominator's conjugate on top and bottom here but that is exactly what I would do here. There will be other problems will you have to do this.
[tex]\frac{\cos(y)}{1-\sin(y)} \cdot \frac{1+\sin(y)}{1+\sin(y)}[/tex]
Big note here: When multiplying conjugates all you have to do is multiply fist and last. You do not need to do the whole foil. That is when you are multiplying something like [tex](a-b)(a+b)[/tex], the result is just [tex]a^2-b^2[/tex].
Let's do that here with our problem in the denominator.
[tex]\frac{\cos(y)}{1-\sin(y)} \cdot \frac{1+\sin(y)}{1+\sin(y)}[/tex]
[tex]\frac{\cos(y)(1+\sin(y))}{(1-\sin(y))(1+\sin(y)}[/tex]
[tex]\frac{\cos(y)(1+\sin(y))}{1^2-\sin^2(y)}[/tex]
[tex]\frac{\cos(y)(1+\sin(y))}{1-\sin^2(y)}[/tex]
[tex]\frac{\cos(y)(1+\sin(y))}{cos^2(y)}[/tex]
In that last step, I apply the Pythagorean Identity I mentioned way above.
Now You have a factor of cos(y) on top and bottom, so you can cancel them out. What we are really saying is that cos(y)/cos(y)=1.
[tex]\frac{1+\sin(y)}{cos(y)}[/tex]
This is the desired result.
We are done.

Find the equation for the linear function that passes through the points (−5,−6) and (10,3). Answers must use whole numbers and/or fractions, not decimals.
A.Use the line tool below to plot the two points_______
B.State the slope between the points as a reduced fraction________
C.State the y-intercept of the linear function_______
D.State the linear function_________
Answer:
Slope: [tex]\frac{3}{5}[/tex]
Y-intercept: -3
Equation: [tex]y=\frac{3}{5} x-3[/tex]
Graph is attached.
Step-by-step explanation:
To find your slope using two points, use the slope formula.
[tex]\frac{y2-y1}{x2-x1} \\[/tex]
Your y1 is -6, your y2 is 3.
Your x1 is -5, your x2 is 10.
[tex]\frac{3-(-6)}{10-(-5)} \\\\\frac{9}{15} \\\\\frac{3}{5} \\[/tex]
Now that you have your slope, use it and one of your points in point-slope form to find your y-intercept.
[tex]y-y1=m(x-x1)\\y-3=\frac{3}{5} (x-10)\\y-3=\frac{3}{5} x-6\\y=\frac{3}{5} x-3[/tex]
Answer:
A. In the graph,
Go 5 units left side from the origin in the x-axis then from that point go downward 6 unit, we will get (-5, -6),
Now, go 10 unit right from the origin in the x-axis then from that point go upward 3 unit, we will get (10, 3),
B. The slope of the line passes through (-5, -6) and (10, 3),
[tex]m=\frac{3-(-6)}{10-(-5)}=\frac{3+6}{10+5}=\frac{9}{15}=\frac{3}{5}[/tex]
C. Since, the equation of a line passes through [tex](x_1, y_1)[/tex] with slope m is,
[tex]y-y_1=m(x-x_1)[/tex]
Thus, the equation of the line is,
[tex]y+6=\frac{3}{5}(x+5)----(1)[/tex]
For y-intercept,
x = 0,
[tex]y+6 = \frac{3}{5}(0+5)\implies y = 3-6=-3[/tex]
That is, y-intercept is -3.
D. From equation (1),
[tex]5y + 30 = 3x + 15[/tex]
[tex]\implies 3x - 5y = 15[/tex]
Which is the required linear function.
I need to be able to take a set of data, and find it's exponential function.
Answer:
The process below should work.
Step-by-step explanation:
Let's pretend we have these two points we are trying to find an exponential equation for: (-2,6) and (2,1).
Exponential equations are of the form [tex]y=a \cdot b^x[/tex] where we must find [tex]a[/tex] and [tex]b[/tex].
So you enter both points into that equation giving you:
[tex]6=a \cdot b^{-2}[/tex]
[tex]1=a \cdot b^{2}[/tex]
I'm going to divide equation 1 by 2 because if I do the a's will cancel and I could solve or b.
[tex]\frac{6}{1}=\frac{a \cdot b^{-2}}{a \cdot b^2}[/tex]
[tex]6=\frac{b^{-2}}{b^2}[/tex]
By law of exponent, I can rewrite the right hand side:
[tex]6=b^{-2-2}[/tex]
[tex]6=b^{-4}[/tex]
Now do ^(-1/4) on both sides to solve for b:
[tex]6^\frac{-1}{4}=b[/tex]
Now we use one of the equations along with our value for b to find a:
[tex]1=a \cdot b^2[/tex] with [tex]b=6^{\frac{-1}{4}}[/tex]
[tex]1=a \cdot (6^{\frac{-1}{4}})^2[/tex]
Simplify using law of exponents:
[tex]1=a \cdot 6^{-\frac{1}{2}}[/tex]
Multiply both sides by 6^(1/2) to solve for a:
[tex]6^{\frac{1}{2}}=a[/tex]
[tex]y=a \cdot b^x[/tex] with [tex]a=6^{\frac{1}{2}} \text{ and } b=6^{\frac{-1}{4}}[/tex] is:
[tex]y=6^\frac{1}{2} \cdot (6^{\frac{-1}{4})^x[/tex]
We can simplify a smidgen:
[tex]y=6^\frac{1}{2} \cdot (6)^\frac{-x}{4}[/tex]
