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]

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

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))

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

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

Answer: 21
Step-by-step explanation: 3 x 7 = 21
Answer:
21
Step-by-step explanation:
so 1 plus 2 which is 3 then do 3 plus 4 which is 7 so 3 times 7 is 21
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. :)

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]

If a cookie recipe has 2 cups of sugar for each cup of flour, how much sugar would you use if you used 6 cups of flour?
Answer:
12 Cups
Step-by-step explanation:
s = 2f
If f = 6
S = 2 x 6
s = 12
Answer:
well u will need to multiply 2 times 6 and it will be 12 can i get brainlyist
Step-by-step explanation:
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)

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.
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.

Answer:
Step-by-step explanation:
From the figure attached,
1). Sin(D) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{EF}{DF}[/tex]
= [tex]\frac{24}{26}[/tex]
= [tex]\frac{12}{13}[/tex]
2). Cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{ED}{DF}[/tex]
= [tex]\frac{10}{26}[/tex]
= [tex]\frac{5}{13}[/tex]
3). tan(D) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{EF}{DE}[/tex]
= [tex]\frac{24}{10}[/tex]
= [tex]\frac{12}{5}[/tex]
4). sin(F) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{DE}{DF}[/tex]
= [tex]\frac{10}{26}[/tex]
= [tex]\frac{5}{13}[/tex]
5). cos(F) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{EF}{DF}[/tex]
= [tex]\frac{24}{26}[/tex]
= [tex]\frac{12}{13}[/tex]
6). tan(F) = [tex]\frac{\text{Adjacent side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{DE}{EF}[/tex]
= [tex]\frac{10}{24}[/tex]
= [tex]\frac{5}{12}[/tex]
