Answer:
(-1,-11)
Step-by-step explanation:
Since the Transformation happened to the g(x)
where we multiplied g(x) by -1 and g(x) represents the y-value
so the y-value will be multiplied by -1
New y-value = 11*-1 = -11
so the New Point will be (-1,-11)

Answer:
Step-by-step explanation:
in 10 hrs distance covered=speed×time=15×10=150 nautical miles.
x²=600²+150²-2×600×150×cos 20°
x²=360,000+22,500-180,000×cos 20°
x=√(382,500+180,000×cos 20°)
x\approx 742.73 nautical miles
time taken=742.73/15 \approx ~49.52 hours
total time taken=10+49.52=59.52 hours
applying sine formula
[tex]\frac{sin ~B}{150} =\frac{sin~20}{742.73} \\\sin~B=\frac{150}{742.73} \times~sin~20\\B=\sin^{-1} [\frac{150}{742.73} \times \sin~20]\\B\approx~3.96 ^\circ\\B\approx 4^\circ[/tex]
so it has to make a turn=20+4=24°

Answer:
This statement is not true. (Alternate Interior Angles Theorem)
Step-by-step explanation:
<6 and <3 are both interior angles, meaning that they are on the interior of two transversals. They are also alternating the transversal, so they are alternate interior angles. The Alternate Interior Angles Theorem states that if a transversal crosses the set of parallel lines, the alternate interior angles are congruent. This means that <6 and <3 would be congruent to one another, so they would have to measure the exact same degree. Hope this helps! :)
Mary and Vincent climbed up a rock wall at the park, Mary climbed 3/4 the way up the wall, Vincent climbed 3/8 of the way up the wall, who climbed higher
Answer:
Mary
Step-by-step explanation:
You have to change the fractions so that the denominator is the same in both of them. To do this, you can multiply the numerator and denominator in 3/4 by 2. This would equal 6/8.
6/8 > 3/8
This shows that Mary climbed higher.
A company that manufacturers coffee for use in commercial machines monitors the caffeine content in its coffee. The company selects 50 samples of coffee every hour from its production line and determines the caffeine content. From historical data, the caffeine content (in milligrams, mg) is known to have a normal distribution with σ = 7.1 n. During a 1-hour time period, the 50 samples yielded a mean caffeine content of y = 110 mg.
a. Identify the population about which inferences can be made from the sample data.
b. Calculate a 95% confidence interval for the mean caffeine content μ of the coffee produced during the hour in which the 50 samples were selected.
c. Explain to the CEO of the company in nonstatistical language the interpretation of the constructed confidence interval.
Tyler has to figure out the amount of metal to cover the back of the shelves in Mrs. Edwards room. These are the dimensions. What is the amount of metal he will need to cover the back of the shelves?
210 square inches
108 square inches
180 square inches
36 square inches
The amount of metal he will need to cover the back of the shelves is 180 inches².
The figure above is like a composite figure. Therefore, lets find the area.
Area of the composite figureThe area of the figure is the sum of the whole individual 2 dimensional shapes in the composite figure.
Therefore, two rectangles can be drawn from it.
area of rectangle = lw
where
l = length
w = width
Therefore,
area of rectangle 1 = 9 × 8 = 72 inches²
area of rectangle 2 = 6 × 18 = 108 inches²
Total area = 108 + 72 = 180 inches²
Therefore, the amount of metal he will need to cover the back of the shelves is 180 inches².

Franklin treated his sister to lunch while visiting her in Ashland. Their lunch cost $75 and the sales tax in Ashland is 8%. If Franklin left a 20% tip on the 75$ how much in total did he pay
Answer: $97.2
Step-by-step explanation: 75+8%/100=81+20%/100=97.2
If their lunch costs $75 and the sales tax in Ashland is 8%. If Franklin left a 20% tip on the 75$. He will totally pay $ 97.2.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
It is given that, Franklin treated his sister to lunch while visiting her in Ashland. Their lunch costs $75 and the sales tax in Ashland is 8%. If Franklin left a 20% tip on the 75$.
We have to apply arithmetic operations in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
If their lunch costs $75 and the sales tax in Ashland is 8%.
= 75+8% of 75
=75+(8/100)×75
=81
If Franklin left a 20% tip on the 75$
=81+20% of 81
=$ 97.2
Thus, if their lunch costs $75 and the sales tax in Ashland is 8%. If Franklin left a 20% tip on the 75$. He will totally pay $ 97.2.

The hypotenuse of a right triangle measures 15 cm and one of its legs
measures 9 cm. Find the measure of the other leg. If necessary, round to the
nearest tenth.
Answer:
12
Step-by-step explanation:
Use Pythagorean Theorem
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
[tex]9^{2}[/tex] + [tex]b^{2}[/tex] = [tex]15^{2}[/tex]
81 + [tex]b^{2}[/tex] = 225
[tex]b^{2}[/tex] = 144 (subtract 81 both sides)
b = 12 (square root each side)
➣ The hypotenuse of a right triangle measures 15 cm.
➣ one of its legs (base) measures 9 cm.
To find -➣ the measure of the other leg (perpendicular).
➣ to round the answer to nearest tenth.
Solution -Here,
p = perpendicular of the triangle
b = base of the triangle
h = hypotenuse of the triangle
Using the Pythagoras Theorem,
(height)² = (perpendicular)² +(base)²
i.e h² = p² + b²
➩ (15)² = p² + (9)²
➩ p² = (15)² - (9)²
➩ p² = 225 - 81
➩ p² = 144
➩ p = √144
➩ p = 12 cm
Hence, the measure of the other leg is 12cm._____________________________

x^2-x+3y=5
x=2y-1
A. Isolate y in the second equation
B. Substitute for x in the first equation
C. Isolate x in the first equation
D. Substitute for y in the second equation
Answer:
B. Substitute for x in the first equation
Step-by-step explanation:
The solution to a system of equations in which one is quadratic and the other is linear will necessarily involve solving a quadratic equation. Generally, we want to arrive at that quadratic as early as possible in the solution process.
Here, we have a linear expression for x, so it is pretty simple to use that to substitute for x in the first equation:
(2y -1)² -(2y -1) +3y = 5 . . . . substitute for x
4y² -4y +1 -2y +1 +3y = 5 . . . . eliminate parentheses
4y² -3y -3 = 0 . . . . quadratic in y in standard form
This does not have integer solutions, so it is perhaps best solved using the quadratic formula.
[tex]y=\dfrac{-(-3)\pm\sqrt{(-3)^2-4(4)(-3)}}{2(4)}=\dfrac{3\pm\sqrt{57}}{8}[/tex]

algebra fraction thing!!! pls explain I'm so lost??? like I don't see why the answer isn't 2n-2? did my teacher make a mistake or am I missing something?
Answer:
a.
Step-by-step explanation:
[tex] \frac{n - 9}{2n - 5} + \frac{3n - 1}{2n - 5} [/tex]
Since the denomaitor is the same, just add straight across.
[tex] \frac{4n - 10}{2n - 5} [/tex]
The numerator can be factored.
The greater common factor is 2 so we have
[tex] \frac{2(2n - 5)}{2n - 5} [/tex]
Notice that the numerator and denomiator are the same.
This means they will divide out to 1 so we have

1. Hannah decided to curl up and read a good book. She started reading at 10:00 a.m. and finished reading at 11:43 a.m. How much time did she spend reading?
1 hour and 43 minutes
if ten to 11 is 1 hr, there is 43 mins left over so the answer is 1 hr 43 mins
so from 10 am to 11 am would 60 minutes (1 hour) and from 11 am hannah spent 43 additional minutes because the finish time reads 11:43 (where the numbers after the ":" sign are minutes) we add the 60 minutes with 43 to get 103 minutes or 1 hour and 43 minutes.
