Racionalización de denominadores 3 / v3 tres sobre raíz cuadrada de 3
da
Usando el método de índices
3 / √3 = 3¹ / 3¹ / ²
= 3¹ / 3⁰.⁵
= 3¹⁻¹ / ²
= 3 ¹ / ²
= √3
Esto también se puede resolver multiplicando tanto el numerador como el denominador por √3
3 / √3 * √3 / √3
= 3√3 / √3 * 3
= 3√3 / √9
= 3√3 / 3
Los tres se cancelan y nos queda √3

gives
Using the method of indices
3 / √3 = 3¹/ 3¹/²
= 3¹/ 3⁰.⁵
= 3¹⁻¹/²
=3 ¹/²
=√3
This can also be solved multiplying both the numerator and the denominator by √3
3 / √3 * √3/√3
= 3√3/ √3*3
= 3√3/ √9
= 3√3/ 3
The three are cancelled and we are left with √3

Answer:
7. 80 miles
8. F
Step-by-step explanation:
7. Jorge leaves 2 hours early, and is going 20 miles per hour. So before Marcos starts going, Jorge has gone 40 miles (2*20). Then, 1 hour later, Jorge is at 60 miles and Marcos is at 40 (because he goes 40 miles per hour in his car). Another hour later, Jorge is at 80 (60+20) and Marcos is at 80 as well (40 + 40). They will both have gone 80 miles when Marcus catches up.
8. You want to get a isolated.
A = h/2(a + b)
First, multiply both sides of the equation by the reciprocal of h/2.
2A/h = a + b
Then, subtract b from both sides.
2A-b/h = a

Can you give me an example on why it’s not foolish to fear ?
Answer:
It is not foolish to fear—it is a matter of survival. The physical responses we have to objects or situations that we fear are often grouped together and characterized as a “fight or flight” instinct. Something alarms you, and instantly your brain causes a number of chemicals to be released into your bloodstream.
Answer:
Fear is already a part of human nature. In fact, fear is used as a defense mechanism of our ancestors long time ago. They used to live on caves, jungles, and not so sturdy shelters that would make them vulnerable enough to different predators. Thus having the feeling of fear saves them by backing down and to retreat unto safer places. Therefore I can say that it's not foolish to fear since it's already a part of us human beings. Even the bravest persons in the world have their own fears too. We can't just separate it from ourselves and let's just embrace it and try to do something to lessen it.

The function f(x) has a vertical asymptote at x= [blank].
Answer:
The vertical assymptote is at x = 0
Step-by-step explanation:
Vertical assymptote are simply defined as lines that correspond to the points where the denominator of a rational function is zero.
From the graph, we can see that the curve remains on the y - axis at x = 0
Thus, the vertical assymptote is x = 0

For which weight of clothing is the ratio of weight to dye different from the other ratios?
21 pounds
42 pounds
84 pounds
105 pounds
Answer: The answer is 42
Step-by-step explanation:
I did the test too :)
The weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.
To determine which weight of clothing has a ratio of weight to dye different from the other ratios, we need to compare the ratios for each weight.
Let's calculate the ratios for each weight of clothing by dividing the weight of clothing (in pounds) by the cups of dye:
For 21 pounds of clothing: 21 pounds / 3 cups = 7 pounds per cup
For 42 pounds of clothing: 42 pounds / 9 cups = 4.67 pounds per cup
For 84 pounds of clothing: 84 pounds / 12 cups = 7 pounds per cup
For 105 pounds of clothing: 105 pounds / 15 cups = 7 pounds per cup
From the calculations, we can see that for weights of 21 pounds, 84 pounds, and 105 pounds of clothing, the ratios of weight to dye are the same, which is 7 pounds per cup. However, the ratio for 42 pounds of clothing is different, which is 4.67 pounds per cup.
Therefore, the weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.

Options :
A(x - 1)
B(x - 10)
C(x - 5)
D(x - 12)
no spam answers and explain how you got the solution.
Answer:
The correct answer is C- (X-5)Solution
Given -
polynomial p(x) = x³ - 23x² + 142x - 120
Now see the coefficients
coefficient of x³ is 1 x² is -23 x is 142 and then -120
when you'll add this coefficients
i.e.
1-23+142-120=0
When sum of the coefficient turn out 0 then x = 1
using x=1, x-1 = 0
devide the given polynomial p(x) = x³ - 23x² + 142x - 120 by x-1 you'll get rest two factors hence

EASY- Han has to build the figure below, which will serve as a counterweight, for his robotics project. Find the VOLUME of the finished object assuming it is empty inside.
Given:
A combined figure of a triangular prism and a cuboid.
To find:
The volume of the finished object assuming it is empty inside.
Solution:
From the given figure it is clear that the dimensions of the cuboid are 6 cm, 8 cm and 5 cm.
So, the volume of the cuboid is:
[tex]V_1=length\times width\times height[/tex]
[tex]V_1=6\times 8\times 5[/tex]
[tex]V_1=240[/tex]
The volume of the cuboid is 240 cubic cm.
The area of a triangle is:
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Thus, the base area of the triangular prism whose base is 8 cm and height 4 cm, is:
[tex]B=\dfrac{1}{2}\times 8\times 4[/tex]
[tex]B=16[/tex]
The volume of a triangular prism is:
[tex]V_2=Bh[/tex]
Where, B is the base area and h is the height of the prism.
The base area of the triangular prism is 16 square cm and the height is 5 cm. So, the volume of a triangular prism is:
[tex]V_2=16(5)[/tex]
[tex]V_2=80[/tex]
Now, the volume of the given figure is:
[tex]V=V_1+V_2[/tex]
[tex]V=240+80[/tex]
[tex]V=320[/tex]
Hence, the volume of the finished object is 320 cubic cm.

Cindy is buying a new car and wants to learn how the value of her car will change over time. Insurance actuaries predict the future value of cars using depreciation functions. One such function is applied to the car whose declining value is shown at the right. Write an exponential function for it.
Answer:
[tex]C=10000(0.852)^t[/tex]
Step-by-step explanation:
Let the exponential function be,
[tex]C=a(b)^t[/tex]
Here, C = cost of the car
t = Duration or period in years
From the given table,
Two points representing cost of the car and time are (10000, 0) and (8520, 1),
For (10000, 0),
[tex]10000=a(b)^0[/tex]
a = 10000
For (8520, 1)
8520 = [tex]10000(b)^1[/tex]
[tex]b=\frac{8520}{10000}[/tex]
b = 0.8520
Therefore, exponential equation will be,
[tex]C=10000(0.852)^t[/tex]

A family wants to remodel a house and spend at most $135,000 total for the entire project. a)If the builder wants to make a 15% profit on the value of the project, what is the largest amount the family can spend on hard costs (materials, labor, engineering, designing, permits) to be able to pay the builder his profit while staying under the $135,000 budget? b)What is the builder's profit? (Hint: You cannot simply take 15% of $135,000 because the $135,000 includes the builder's profit. Just like in our commission problems, you don't make commission on commission. The percentage is applied to the value of goods and services provided.)

Louis wants to buy skis that have a regular price of $328. They have been marked down 25% off the regular price. Louis calculates the new total price including tax.
How much money will Louis save on the total cost because of the markdown?
Answer:
Part ACalculate sale price and add sales tax:
20% off $339 add tax ⇒ $339*0.8*1.085 = $294.25 ≤ $30015% off $310 add tax ⇒ $310*0.85*1.085 = $285.90 ≤ $30025% off $365 add tax ⇒ $365*0.75*1.085 = $297.02 ≤ $30020% off $300 add tax ⇒ $300*0.8*1.085 = $260.40 ≤ $300Each price is acceptable as less than $300
Part BMarkdown with tax added:
25% off $328 add tax ⇒ $328*0.75*1.085 = $266.91Without discount, the price with the tax added:
$328*1.085 = $355.88The difference is the amount Luis has saved:
$355.88 - $266.91 = $88.97
