Answer:
n = - [tex]\frac{4}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] (1 + n) = - [tex]\frac{1}{2}[/tex] n
Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions
4(1 + n) = - 3n ← distribute left side
4 + 4n = - 3n ( add 3n to both sides )
4 + 7n = 0 ( subtract 4 from both sides )
7n = - 4 ( divide both sides by 7 )
n = - [tex]\frac{4}{7}[/tex]

Oall real numbers except 8pi+8npi, where n is any integer
Answers
Answer:
B) all real numbers expect 4pi+8pi where n is any integer
Step-by-step explanation:
The domain of the function y = tan(x/8) is given by: All real numbers except 4π+8nπ , where n is any integer.
What is the domain of a function?The domain is the set that contains all possible input values for the function.
Since we know that Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:
π/2 + nπ
Hence, let a composite tangent function , the domain is given by:
f(x) does not equal to π/2 + nπ
we have that , hence the domain is:
all real numbers except 4π+8nπ
All real numbers except 4π+8nπ, where n is any integer.

Kevin Hill deposited 15,483 pennies. He put 50 pennies in each penny roll. How many full rolls did he have?
Answers
Answer:
309 full rolls
Step-by-step explanation:
Find how many full rolls he had by dividing 15,483 by 50:
15,483/50
= 309.66
Since the question asks for full rolls, the answer has to be a full number.
So, the answer is 309 full rolls

Two forces, one of 45 pounds and the other 50 pounds, act on the same object. The angle between the forces is 33°. Find the magnitude of the resultant vector. Pls help :( cant afford to fail
Answers
Answer:
The magnitude of the resultant force is: 27.40 pounds
Step-by-step explanation:
Given
[tex]F_1 = 45[/tex]
[tex]F_2 = 50[/tex]
[tex]\theta = 33[/tex]
Required
The magnitude of the resultant vector
To do this, we apply cosine formula
[tex]R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)[/tex]
This gives:
[tex]R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)[/tex]
[tex]R^2 = 2025+ 2500 - 4500* 0.8387[/tex]
[tex]R^2 = 2025+ 2500 - 3774.15[/tex]
[tex]R^2 = 750.85[/tex]
Take square roots of both sides
[tex]R = \sqrt{750.85\\[/tex]

brown/red-haired people are there in the class? (Everyone in the class has either brown or red hair)
Answers
Answer:
8 red haired and 42 brown haired
Step-by-step explanation:
I chose a random number to start off with (which is 8) and I multiplied it by 5.
8•5=40 and then you have to add 2, so you get 42.
42+8 = 50
The equation would be (5x+2)+x where 'x' is the number of people with red hair.

There are two angles given.
One is 90 and the other is 45.
90+45=135
180-135=45°
This proves that the triangle is isosceles.
This means that two angles are equal, but also two side lengths are the same.
In this triangle, the equal sides are CB and AC.
Therefore, AC is equal to 9.

Select the correct location on the table. Consider the following equation. Square root of 2x+3 = x/x+5 + 2 which row in the table is closest to the actual solution
Answers
Answer:
0.8 i guess
Step-by-step explanation:
The row including x=0.7 in the table is the closest to the actual solution for the expression [tex]\sqrt{(2x+3)}=\dfrac{x}{(x+5)}+2[/tex].
Solution of Algebraic EquationIn order to find the actual solution of any algebraic expression, we can graph it and the point at which the graph intersects the axis is its actual solution.
How to find the solution of the algebraic equation?First, we will find the actual solution of the expression [tex]\sqrt{(2x+3)}=\frac{x}{(x+5)}+2[/tex] by graphing it.
From the graph, we can see that the expression intersects when x=0.7 so, the actual solution is 0.7.
Thus, the 0.7 row in the table is the closest to the actual solution.
