Answer:
your marked choice is correct: x = e
Step-by-step explanation:
For the line to go through the origin, the ratio of ln(x) to x at the point must equal the slope at the point.
The slope of ln(x) is 1/x, so we require ...
ln(x)/x = 1/x
ln(x) = 1 . . . . . . multiply by x
x = e . . . . . . . . take antilogs

Step-by-step explanation:
Start with n=1. Put the value where n is in the expression and do the arithmetic.
a1 = 3·1 -5 = -2
a2 = 3·2 -5 = 1
a3 = 3·3 -5 = 4
a4 = 3·4 -5 = 7

What is the Calculate
Answer:
From the given figure, we can see that
∠LON = ∠LOM + ∠MON
replacing the variables with the given values
77 = 9x + 44 + 6x + 3
77 = 15x + 47
15x = 30
x = 2
Finding ∠MON:
we are given that ∠MON = 6x +3
now that we know the values of x,
∠MON = 6(2) + 3
∠MON = 12 + 3
∠MON = 15°

Perfect Purple Water The recipe for Perfect Purple Water says, "Mix 8 ml of blue water with 3 ml of red water." lada mixes 24 ml of blue water with 9 ml of red water. Andre mixes 16 ml of blue water with 9 ml of red water. . Which person will get a color mixture that is the same shade as Perfect Purple Water? Explain or show your reasoning.
Analysing the question:
We are given that the ratio between the blue and red color is 8 : 3
as long as the volumes of the colours added simplify to 8 : 3 , the color will be Perfect Purple
Lada's Solution:
Lada mixed 24 mL of blue water with 9 mL of red water
we will try to simplify this ratio:
24:9 = 24 / 9
8 / 3
8 : 3
Hence, the ratio of the colours in Lada's mixture is correct. So, Lada will get perfect purple water
Andre's Solution:
Andre mixed 16mL of Blue water with 9 mL of red water
we will try to simplify this ratio:
16 : 9 = 16 / 9
THIS RATIO CANNOT BE SIMPLIFIED
Hence, the ratio of blue and red color in Andre's mixture is 16 : 9
but the ratio for a perfect purple color is 8 : 3
Since the ratio in Andre's mixture is incorrect, she will NOT get the perfect purple colour
Answer:
Lada will get a color mixture that is the same shade as Perfect Purple Water.
Step-by-step explanation:
Proportions
The mix for Perfect Purple Water contains 8 ml of blue water with 3 ml of red water.
The exact proportion of both ingredients is, blue to red:
[tex]\displaystyle \frac{8}{3}[/tex]
Lada mixes 24 ml of blue water with 9 ml of red water. The proportion is:
[tex]\displaystyle \frac{24}{9}[/tex]
Simplifying by 3:
[tex]\displaystyle \frac{8}{3}[/tex]
The proportion obtained by Lada is the same shade as Perfect Purple Water.
Andre mixes 16 ml of blue water with 9 ml of red water, his proportion is:
[tex]\displaystyle \frac{16}{9}[/tex]
This fraction cannot be reduced and its result is not exactly the same as the perfect required proportion.
Thus, Lada will get a color mixture that is the same shade as Perfect Purple Water.

The midpoint of AB is M(3,3). If the coordinates of A are (2, -1), what are the
coordinates of B?
Answer:
(4, 7)
Step-by-step explanation:
Given that:
Midpoint of AB = M(3, 3)
Coordinate of A = (2, - 1)
Let coordinates of B = (x, y)
Recall :
Midpoint of AB = [(Ax + Bx) / 2, (Ay + By) / 2]
Mx = (Ax + Bx) / 2
My = (Ay + By) / 2
Mx = 3
Mx = (Ax + Bx) / 2
3 = (2 + x) / 2
2*3 = 2 + x
6 = 2 + x
6 - 2 = x
4 = x
My = 3
My = (Ay + By) / 2
3 = (-1 + y) / 2
2*3 = - 1 + y
6 = - 1 + y
6 + 1 = y
7 = y
Hence,
B = (4, 7)
