Question 2 help please
Answer:
The measure of the vertex angle is 94 degrees ⇒ A
Step-by-step explanation:
In any triangle, the sum of the measures of its interior angle is 180°In the isosceles triangle, the two base angles are equal in measures∵ In an isosceles triangle, the measure of the base angle = (2x + 5)
∵ The base angles of the isosceles triangles are equal in measures
∴ The measures of the base angles are (2x + 5), (2x + 5)
∵ The measure of the vertex angle = (5x - 1)
∵ The sum of the measure of the three angles = 180°
∴ (2x + 5) + (2x + 5) + (5x - 1) = 180
→ Add the like terms in the left side
∵ (2x + 2x + 5x) + (5 + 5 + -1) = 180
∴ 9x + 9 = 180
→ Subtract 9 from both sides
∴ 9x + 9 - 9 = 180 - 9
∴ 9x = 171
→ Divide both sides by 9 to find x
∴ x = 19
→ Substitute the value of x in the measure of the vertex angle to find it
∵ The measure of the vertex angle = 5x - 1
∴ The measure of the vertex angle = 5(19) - 1
∴ The measure of the vertex angle = 95 - 1
∴ The measure of the vertex angle = 94°
∴ The measure of the vertex angle is 94 degrees

En el estante de un negocio hay 2 tipos de tarros de la misma mermelada y marca. El tarro más alto tiene el doble de altura que el otro, pero su diámetro es la mitad del diámetro del otro. El tarro más alto vale $4.500 y el más bajo $8.000, ¿ cuál es la mejor compra ? help
Answer:
tarro corto
Step-by-step explanation:
Aquí tenemos que comprar el frasco que tiene el menor costo por volumen.
[tex]h_1[/tex] = Altura del frasco corto
[tex]h_2[/tex] = La altura del frasco alto es el doble que el del frasco corto. = [tex]2h_1[/tex]
[tex]d_1[/tex] = Diámetro del frasco corto
[tex]d_2[/tex] = El diámetro del frasco alto es la mitad del frasco corto = [tex]\dfrac{1}{2}d_1[/tex]
El volumen de un cilindro es [tex]\pi \dfrac{d^2}{4}h[/tex]
La razón de los volúmenes de los frascos es
[tex]\dfrac{V_1}{V_2}=\dfrac{\pi\dfrac{d_1^2}{4}h_1}{\pi\dfrac{d_2^2}{4}h_2}\\\Rightarrow \dfrac{V_1}{V_2}=\dfrac{d_1^2h_1}{d_2^2h_2}\\\Rightarrow \dfrac{V_1}{V_2}=\dfrac{d_1^2h_1}{(\dfrac{1}{2}d_1)^22h_1}\\\Rightarrow \dfrac{V_1}{V_2}=\dfrac{d_1^2h_1}{\dfrac{1}{4}d_1^22h_1}\\\Rightarrow \dfrac{V_1}{V_2}=\dfrac{1}{\dfrac{1}{2}}\\\Rightarrow \dfrac{V_1}{V_2}=2\\\Rightarrow V_1=2V_2[/tex]
El costo del frasco corto por unidad de volumen es
[tex]\dfrac{8000}{V_1}=\dfrac{8000}{2V_2}=\dfrac{4000}{V_2}[/tex]
El costo del frasco alto por unidad de volumen es
[tex]\dfrac{4500}{V_2}=\dfrac{4500}{V_2}[/tex]
[tex]\dfrac{4000}{V_2}<\dfrac{4500}{V_2}[/tex]
Entonces, el costo del frasco corto por unidad de volumen es menor que el costo por unidad de volumen del frasco alto.
Por lo tanto, deberíamos tomar el frasco corto.

One purpose of General T.Sherman's march to the sea was to
a) break the spirits of confederate citizens
b) allow troops under his control to get rest
c) find ships and sail his soldier's to the north
d) prove that he was the most skilled union general
Answer:
A
Step-by-step explanation: He slashed across the South destroying farms and land in a scorched Earth tactic, which was really damaging to the South because the land they had was all they had.
It's not B because they didn't need rest, he wasn't sailing North so it's not C, and he didn't have anything to prove himself as a skilled general, he already was a skilled general.

Linda is riding on a bike course that is 60 miles long. So far, she has ridden 54 miles of the course. What percentage of the course has Linda ridden so far?
Answer:
Linda has ridden 90% of the course
Step-by-step explanation:
To find the percentage the formula is
distance ridden so far/total distance X 100
54/60 X 100
= 0.9 X 100
= 90
=90%
Therefore Linda has ridden 90% of the course.

The automaker of your new car recommended an oil change following the 5,000 miles and then every 3,000 miles thereafter.if you plan to drive the car 250 miles a week, how many oil changes will you need the first year?
Answer:
3 oil changes
Step-by-step explanation:
1. Find an equation that represents this word problem: 3000x + 5000 = y
Where y = the # of miles total. y = 250 miles/week * 52 weeks/year = 13000 miles.
2. Solve for x: 3000x + 5000 = 13000 3000x=8000
3. x = 8/3 integer round down x = 2 oil changes, but plus the one after 5000 miles is a total of 3 oil changes that year

Karen earns $54.60 for working 6 hours. If the amount she earns varies directly with the
number of hours she works, how many hours would she need to work to earn an
additional $260?
Given:
Karen earns $54.60 for working 6 hours.
Amount she earns varies directly with the number of hours she works.
She need to work to earn an additional $260.
To find:
Number of hours she need to work to earn an additional $260.
Solution:
Let the amount of earnings be A and number of hours be t.
According to question,
[tex]A\propto t[/tex]
[tex]A=kt[/tex] ...(i)
where, k is constant of proportionality.
Karen earns $54.60 for working 6 hours.
[tex]54.60=k(6)[/tex]
Divide both sides by 6.
[tex]\dfrac{54.60}{6}=k[/tex]
[tex]9.1=k[/tex]
Put k=9.1 in (i).
[tex]A=9.1t[/tex]
Substitute A=260 in the above equation.
[tex]260=9.1t[/tex]
Divide both sides by 9.1.
[tex]\dfrac{260}{9.1}=t[/tex]
[tex]28.5714=t[/tex]
[tex]t\approx 29[/tex]
Therefore, she need to work extra about 29 hours to earn an additional $260.
a) Given g(x) = 4x – 3, what function h(x) would represent a downward shift by two units? Show your solution.
b) Sketch the original function g(x) =4x -3 and the new function that you got from letter a.
Reflect g(x) = x3 + x2 - 3x - 1 across the y -axis. What is the new function and show your work?
a) The solution to the transformation of the function is h ( x ) = 4x - 5
b) The reflection of function g ( x ) over y axis is f ( x ) = -x³ + x² + 3x - 1
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the function be represented as g ( x )
Now , the value of g ( x ) = 4x - 3
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
On transformation of the function by a vertical shift of 2 units , we get
h ( x ) = g ( x ) - 2
Substituting the values in the equation , we get
h ( x ) = 4x - 3 - 2
h ( x ) = 4x - 5
So , the transformed function is h ( x ) = 4x - 5
b)
On reflecting the function g ( x ) over y axis , f ( x ) = g ( -x )
Substituting the value of x as -x in the function , we get
g ( -x ) = ( -x )³ + ( -x )² - 3 ( -x ) - 1
So , f ( x ) = -x³ + x² + 3x - 1
Hence , the transformed function is h ( x ) = 4x - 5

Kristi gets $10 a week from her parents if she washes the dishes after dinner every night. Kristi has saved up $30 over the last few weeks from her allowance. She wants to continue saving her allowance until she has enough money to buy the $7o bike she saw at the store last week. Assuming Kristi receives her allowance every week, write an equation that shows how many more weeks Kristi has to save her allowance to buy the bike, where w is the number of weeks. You can solve the equation to check your answer.
Answer: She needs to save her allowance for another 4 weeks.
Step-by-step explanation:
She starts with $30, and for each week that she saves her allowance, she gets another $10. If she saves for "w" weeks, she has:
$30 + w*$10
And she wants to have $70
$30 + w*$10 = $70
We can solve this:
$30 + w*$10 = $70
w*$10 = $70 - $30 = $40
w = $40/$10 = 4
