Answer:
[tex]x=0.61485921[/tex]
Step-by-step explanation:
The given equation is in exponential form:
[tex]6^{4x} =82[/tex]
To find [tex]x[/tex] we need to write it in logarithmic form:
[tex]b^{a} =n[/tex] ⇒ [tex]log_{b} n=a[/tex]
[tex]6^{4x} =82[/tex] ⇒ [tex]log_{ 6 } 82=4x[/tex]
[tex]2.45943684 = 4x[/tex]
[tex]\frac{2.45943684}{4} = x[/tex]
[tex]0.61485921 =x[/tex]
To prove this, we can substitute the value into the given equation
[tex]6^{4x} =82[/tex]
[tex]6^{4(0.61485921)} =82[/tex]
[tex]82=82[/tex]
Therefore, the answer is [tex]x=0.61485921[/tex]

what is 5 times a number minus 3 is 12 ?
Answer:
5*x-3=12
the number is 3 because 5*3=15 and 15-3=12
Answer:
3
Step-by-step explanation:
x - 3 = 12
12 + 3 = 15
15 - 3 = 12
5( ? ) = 15
15/5
? = 3
5(3) = 15 - 3 = 12

Brent leaves school to go home. He walks 10 blocks north and then 6 blocks west. If Brent could walk in a straight line to the school, what is the exact distance between Brent and school
Answer:
11.66 units
Step-by-step explanation:
Given that he walks 10 blocks north and then 6 blocks west..
When combined with the straight line to the school, this forms a right angled triangle with the straight line as the hypotenuse.
Hence, let the straight line be h
h^2 = 10^2 + 6^2 (using Pythagoras theorem)
h^2 = 100 + 36
h^2 = 136
h = √ 136
h = 11.66 units

12. The function M(h) = 10e-0.173h can be used to find the number of milligrams M of morphine that is
in the patient's bloodstream h hours after the drug has been administered.
(a) What was the initial dosage?
(b) How many milligrams will be present after 1 hour? After 4 hours?
please help..
Answer:
Part A; Initial dosage is 10 milligrams
Part B:
8.4113 milligrams after 1 hour
5.0057 milligrams after 4 hours.
Step-by-step explanation:
It is given M(h)= 10 [tex]e^{-0.173h}[/tex]
Initial dosage is the 10 milligrams
After 1 hour, plug in h as 1
So, M(1)=10[tex]e^{-0.173*1}[/tex]
Simplify the right side
M(1)=10(0.84113)
M(1)= 8.4113 milligrams.
Now, after 4 hours
M(4)=10 [tex]e^{-0.173*4}[/tex]
M(4)=10(0.50057)
M(4) =5.0057 milligrams

Consider the rectangle. Which pair of expressions represents the perimeter of the rectangle?
PLEASE HELP!!!
Answer:
6x + 2 and 2x + (x + 1) + 2x + (x + 1)
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Length = 2x
Width = x + 1
Perimeter of a rectangle = 2(length + width)
= 2{2x + (x + 1)}
= 2(2x + x + 1)
= 2(3x + 1)
= 6x + 2
Perimeter = length + width + length + width
= 2x + (x + 1) + 2x + (x + 1)

Students at Sunnyside Middle School are selling tickets to the annual talent show. Below is a table showing ticket prices for students and adults.
Talent show ticket prices
Student Price $3
Adult Price $5
What amount of money would be collect if 60 students and 30 adults bought tickets? Show or explain how you got your answer.
Answer:
$330
Step-by-step explanation:
$3 times 60 students = $180
$5 times 30 adults = $150
$180 + $150 = $330
Answer:
Step-by-step explanation:
you would find your answer by multiplying the amount of students/adults by how much each ticket costs
60 x $3 = $180
30 x $5 = $150
$180 + $150 = $330

1. Let x= -2 and y= -5. (NC.7.NS.2) Which expression has a negative value? A. X+y B.X-y C.[x] [y] D. X/y
Answer:
A. X + Y
Step-by-step explanation:
From this question x = -2 and y = -5
We are to find out the expression that would give a negative value.
X+Y
(-2)+(-5)
+(-) gives a negative sign. So we have
= -2-5
= -7
For x - y
(-2) - (-5)
-(-) = positive
= -2 + 5
= 3.
For [x][y]
= (-2) x (-5)
= 10
since a negative sign multiplied with another negative sign gives a positive result
For X/Y
= -2/-5
= 2/5 the result here is positive because 2 negative signs when divided cancel out.
Therefore the answer is option A since it's result is negative. Others are positive

Please Help!!! Find the approximate volume by using 3.14 (not the pi key) Round to the nearest hundredth when necessary show your work!
The approximate volume of first cone is 709[tex]mi^{3}[/tex] and the volume of second cone is 262 [tex]cm^{3}[/tex].
What is volume?Volume is amount of substance a container can hold in its capacity. Volume of cone is basically 1/3 *π[tex]r^{2}h[/tex] in which r is radius and h is height of cone.
How to calculate volume?We have been given two cones. First is having radius of 7 mi and
height 14 mi and second is having radius of 5 cm and height of 10 cm. We are required to find out the volume of both the cones.
Volume of first cone=1/3 *π[tex]7^{2}* 14[/tex]
=(49*3.14*14)/3
=708.86
Approximately 709 [tex]mi^{3}[/tex]
Volume of second cone =1/3π[tex]5^{2} *10[/tex]
=(25*3.14*10)/3
=261.67
Approximately 262 [tex]cm^{3}[/tex].
Hence the approximate volume of first cone is 709[tex]mi^{3}[/tex] and the volume of second cone is 262 [tex]cm^{3}[/tex].

Video club A charges $10 for membership and. $4 per movie rental. Video club B charges $15 for membership and $3 per movie rental. For how many rentals will be cost be the same at both video clubs? What is that cost?
Answer:
5 rentals for $30
Step-by-step explanation: *using y = mx + b*
Info Given:
Video Club A-
$10 (would be your b)
$4 (would be your x)
Video Club B-
$15 (would be your b)
$3 (would be your x)
HOW TO SOLVE:
Video Club A - y = 4x + 10
Video Club B - y = 3x + 15
Set them equal to eachother to solve for x!
4x + 10 = 3x + 15
- 10 - 10
4x = 3x + 5
-3x -3x
x = 5 rentals
Plug in the x into both or just one equation to find the price!
y = 4x + 10
= 4(5) + 10
= 20 + 10
y = $30
