Answer:
El alemán debe recorrer de la ciudad B a la ciudad A para llevar los cilindros de gas de cloro.
Step-by-step explanation:
De acuerdo con este problema, tenemos un ángulo y dos lados adyacentes, por tanto, podemos determinar la distancia entre las ciudades A y B, medida en kilómetros, por la Ley del Coseno, definida como sigue:
[tex]AB = \sqrt{AC^{2}+BC^{2}-2\cdot AC\cdot BC\cdot \cos C}[/tex] (1)
Donde:
[tex]AC[/tex] - Distancia entre las ciudades A y C, medida en kilómetros.
[tex]BC[/tex] - Distancia entre las ciudades B y C, medida en kilómetros.
[tex]C[/tex] - Ángulo en la ciudad C, medida en grados sexagesimales.
Si tenemos que [tex]AC = 5\,km[/tex], [tex]BC = 8\,km[/tex] y [tex]C = 36^{\circ}[/tex], entonces:
[tex]AB = \sqrt{(5\,km)^{2}+(8\,km)^{2}-2\cdot (5\,km)\cdot (8\,km)\cdot \cos 36^{\circ}}[/tex]
[tex]AB \approx 4,927\,km[/tex]
El alemán debe recorrer de la ciudad B a la ciudad A para llevar los cilindros de gas de cloro.

Hi there!
[tex]\large\boxed{\text{ She is incorrect.}}[/tex]
The format of a logarithmic equation is:
[tex]a^{b} = c\\\\log_{a}c = b[/tex]
In this instance:
a = e
b = 3x
c = 7
Rewrite as the logarithmic equation:
[tex]log_{e}7 = 3x[/tex]
Solve. Evaluate [tex]log_{e}7[/tex] and use algebra to find x:
[tex]1.946 = 3x\\\\x = 0.649[/tex]
Tell which equation you would choose to solve for one of the variables. Explain.
5x + 3y = 11
5x – y = 5

The point (-3, 15) undergoes a translation of 9 units right and 10 units down. What are the coordinates of the new
point?
(-12,10)
® (-12,5)
(6,10)
D (6,5)
Answer:
This would be D. (6, 5)
Step-by-step explanation:
When moving 9 to the right, you take -3 and add 9 to it, which gives you 6.
Do the same thing with 15, but subtract 10 from it, since you are going to the left. This gives you 5.
Therefore, your answer should be (6, 5)
-3 + 9 = 6
15 + 10 = 5
Find a ratio that compares the relative sizes of the quantities 23 inches to 5 feet

Find the slope of the line passing through the points (9, 1) and (-3, -3). Describe the slope as positive, negative, zero, or undefined. The slope equals The slope is (select)
Answer:
Given points:-(9,1)(-3,-3)We have to find slope =m
As we know that[tex]{\boxed{\sf Slope_{(m)}=\dfrac {y _2-y_1}{x_2-x_1}}}[/tex]
Substitute the values[tex]\qquad {:}\longrightarrow\sf m=\dfrac {(-3-1)}{(-3-9)}[/tex]
[tex]\qquad {:}\longrightarrow\sf m=\dfrac {-4}{-12}[/tex]
[tex]\qquad {:}\longrightarrow\sf m={\dfrac {1}{3}}[/tex]
[tex]\therefore\sf Slope\;of\;the\:line=\dfrac {1}{3}(undefined)[/tex]

Answer:
A) 40 + d
B) 45 days
Step-by-step explanation:
A)
total cost = (cost of the air conditioner itself) + (money charged per day)*(days)
cost of air conditioner itself = $40
money charged per day = $1
days = d
40 + 1*d
= 40 + d
B)
total cost = 40 + d
total cost = $85
85 = 40 + d
45 = d
Time used the air conditioner for 45 days.

Answer:
c, 50
Step-by-step explanation:
120-24= 96
Since we are measuring the size of one of the halves, you have to split that number in half, so 96 ÷ 2= 48.
48 rounds up to 50, so 50 is the answer
Select all the solutions to (x - 2)2 = -16.
a
x = 6
b
X = -2
с
x = -6
d
x = 2 + 4i
e
X = 2 + 2i
f
x = 2 - 2
bin
X = 2 - 4
Answer:
d and g
Step-by-step explanation:
Given
(x - 2)² = - 16 ( take the square root of both sides )
x - 2 = ± [tex]\sqrt{-16}[/tex] = ± [tex]\sqrt{16(-1)}[/tex] = ± 4i ( add 2 to both sides )
x = 2 ± 4i
Thus
x = 2 + 4i → (d)
x = 2 - 4i → (g)

Given that
x:y= 5:4 and y: z = 3:2
Find the ratio x:y:z
Give your answer in its simplest form.
Answer:
15:12:16
Step-by-step explanation:
x:y= 5:4
y:z= 3:2
5×3= 4×3
3×4= 2×8
15= 12
12= 16
Therefore x:y:z can be shown as follows
= 15:12:16
Enter the number in two equivalent froms
The decimal equivalent is 0.60, and the percent is 60%. If you do 3/5, you get 0.60, and to get the percentage, you move the decimal two to the right, and add the percent sign. I hope you understand. :)
Mr.semmler drove 110 miles in 2 hours. At this rate, how many miles will he drive in 6 hours?
Answer:
330 miles
Step-by-step explanation:
If in 2 hours he drove 110 and you need to know how much miles will he have drove in 6, first you need to know if 2 is a multiple of 6, in this case it is so now you just divide 6/2 which is 3 so you multiply 110X3 wich gives you 330

Analyze Timothy's steps. Is he correct? If not, why not? Yes, he is correct. No, he needed to add the exponents when he simplified the powers of the same base. No, he needed to multiply 3 and –1 instead of creating a positive exponent in a fraction. No, his value of (negative 4) squared should be positive because an even exponent indicates a positive value.
Complete question is;
Tiothy evaluated the expression using x = 3 and y = –4. The expression is (xy^(-2))/(3x²y^(−4))
1. (1/3)x^(−1)(y²) 2. ((1/3)^(3−1))(−4²) 3. (1/3)(1/3)(−4)² 4. (1/3)(1/3)(−16) 5. −16/9 Analyze Timothy's steps. Is he correct? If not, why not?
A) Yes, he is correct.
B) No, he needed to add the exponents when he simplified the powers of the same base.
C) No, he needed to multiply 3 and –1 instead of creating a positive exponent in a fraction.
D) No, his value of (negative 4) squared should be positive because an even exponent indicates a positive value.
Answer:
D) No, his value of (negative 4) squared should be positive because an even exponent indicates a positive value.
Step-by-step explanation:
The expression is;
(xy^(-2))/(3x²y^(−4))
Simplifying this using law of indices gives;
⅓(x^(1 - 2)) × (y^(-2 -(-4))
This gives;
= (⅓x^(-1)) × y²
= ⅓ × (1/x) × y²
We are told that x = 3 and y = –4, thus;
= ⅓ × ⅓ × (-4)²
Square of a negative number is positive, thus (-4)² = 16
Thus;
⅓ × ⅓ × (-4)² = 16/9
Looking at the answer Timothy got, it's clear he made a mistake of not getting a positive number when he squared -4.
Thus,option D is the correct answer.

D

Show that the cosine law simplifies to the Pythagorean theorem when the contained angle between the two known sides is 90°.
Answer:
See Below.
Step-by-step explanation:
We want to show that the Law of Cosines simplifies to the Pythagorean Theorem when the contained angle between the two known sides is 90°.
The Law of Cosines is given by:
[tex]c^2=a^2+b^2-2ab\cos(C)[/tex]
Where a and b are the two known sides, and C is the angle between them.
If C is 90° then we will have:
[tex]c^2=a^2+b^2-2ab\cos(90 ^\circ)[/tex]
Recall that the cos(90°)=0. Hence:
[tex]c^2=a^2+b^2-2ab(0)[/tex]
Simplify:
[tex]c^2=a^2+b^2[/tex]
So, we acquire the Pythagorean Theorem as desired.
