solve the liner equation: -8(4x+6)= -24
Answer:
-3/4
Step-by-step explanation:
Answer:
x= -3/4
Step by Step explanation:
Step 1: Simplify both sides of the equation.
−8(4x+6)=−24
(−8)(4x)+(−8)(6)=−24 (Distribute)
−32x+−48=−24
−32x−48=−24
Step 2: Add 48 to both sides.
−32x−48+48=−24+48
−32x=24
Step 3: Divide both sides by -32.
-32x/-32 =24/-32

Answer:
A
Step-by-step explanation:
I am a little confused with the "all trees $42" answer but if that means she could buy that size for $42 then I believe that is the answer that should be chosen because for question B, 6 per ft. would likely be 48 because 6x8 = 48, and I don't believe half ft would be $3. As for C, 22 plus 24 is 46. (24 would = $6 x 4 additional ft)
Question 18. Suppose we have a piece of cardboard that is 40 cm by 25 cm.
Answer:
a. The length of the box = (40 - 2·x) cm
The height of the box = x cm
The width of the box = (25 - 2·x) cm
b. The formula for the volume of the box as a function of x is 4·x³ - 130·x² + 1000·x
c. The value of x that would maximize the volume of the box is x = 5 cm
d. The largest volume of the box is 2250 cm³
Step-by-step explanation:
a. The given parameters are;
The length of the cardboard = 40 cm
The width of the cardboard = 25 cm
The length of the box = (40 - 2·x) cm
The height of the box = x cm
The width of the box = (25 - 2·x) cm
b. The formula for the volume of the box = The area of the base of the box × Height of the box
The area of the base of the box = (40 - 2·x) × (25 - 2·x) = 1000 - 80·x - 50·x + 4·x²
∴ The area of the base of the box = 4·x² - 130·x + 1000
The height of the box = x
The volume of the box = (4·x² - 130·x + 1000) × x = 4·x³ - 130·x² + 1000·x
The volume of the box in terms of x, V = 4·x³ - 130·x² + 1000·x
c. At the extremum point, dV/dx = 12·x² - 260·x + 1000 = 0
x = (260 ± √((-260)² - 4 × 12 × 1000))/(2 × 12)
x = (260 ± 140)/(24)
x = 5 or x = 16.[tex]\bar 6[/tex]
At x = 5, the volume of the box is V = 4×5³ - 130×5² + 1000×5 = 2250
The volume of the box is V = 2250 cm³
At x = 16.67, the volume is 4×16.67³ - 130×16.67² + 1000×16.67 = -925.[tex]\overline {925}[/tex]cm³
Therefore, the value of x that would maximize the volume of the box is x = 5 cm
d. The largest volume of the box is 4×(5 cm)³ - 130×(5 cm)² + 1000×(5 cm) = 2250 cm³.

Consider a 176lb male farmer is in 104 degree heat. On this day, the humidity is low enough such that all the sweat evaporates from the farmer's skin, enabling him to maintain a body temperature of 100 degrees. The farmer sweats 1 liter of water per hour and 60% of the latent heat needed to Evan=pirate this sweat is provided by farmer's body. If the farmer suddenly dehydrates and stops sweating, how long will it take for his body temperature to rise to the near-fatal 104 degrees.
Answer:
t = 33 seconds
It is the amount of time when the temperature of the body will rise from 100 to fatal 104 in the absence of sweat.
Step-by-step explanation:
weight of the farmer = 176 lb
Sweating = 1 litre per hour
60% of above sweating is evaporated by the latent heat from farmers body.
Temperature outside = 104
Temperature of the Farmer = 100
Time to rise the temperature 4 degrees = ?
We need to use the specific heat formula to calculate the time to rise the temperature of the body of farmer.
Before, that let's convert weight of the farmer in Kg
W = 176 lb
1 lb = 0.453592 kg
176 lb = 79.8 kg
w = mg
g = 10
mass = m = 79.8/10
mass = 7.98 kg
Q = mc∆T
c = specific heat of water = 4,186
∆T = Temperature Change = 104-100
∆T = 4
Q = 7.98 x 4186 x 4
Q = 133617
t = Q/P
Power of Sun's Heat = 3.846×1026
t = 33 seconds
It is the amount of time when the temperature of the body will rise from 100 to fatal 104 in the absence of sweat.

495 = 165 + 55m
What is m?
Answer: M = 6 can i have brainliest?
Step-by-step explanation:
Answer:
m=6
Step-by-step explanation:
First isolate the m by subtracting 165 from both sides.
495-165=330
165-165=0
330=55m
Since you know 330 is 55m to find m all you need to do is divide by 55 on both sides.
330/55=6
55m/55=m
6=m

what is tan theta when csc theta =2 sqrt 3?
Not really understanding how this works. If possible can someone explain step by step?
Answer:
[tex]\displaystyle \tan\theta=\frac{\sqrt{11}}{11}[/tex]
Step-by-step explanation:
Trigonometric Identities
If the trigonometric function value of an angle is given, we can find the rest of the trigonometric values of the angle by using one or more of the fundamental identities.
To solve this problem, we need to use the following identities:
[tex]\displaystyle \cot^2\theta=\csc^2\theta-1[/tex]
[tex]\displaystyle \tan\theta=\frac{1}{\cot\theta}[/tex]
Since we are given:
[tex]\displaystyle \csc\theta=2\sqrt{3}[/tex]
And the angle is in the first quadrant, calculate the cotangent:
[tex]\displaystyle \cot^2\theta=(2\sqrt{3})^2-1[/tex]
[tex]\displaystyle \cot^2\theta=4*3-1=11[/tex]
[tex]\displaystyle \cot\theta=\sqrt{11}[/tex]
The tangent is:
[tex]\displaystyle \tan\theta=\frac{1}{\sqrt{11}}[/tex]
Rationalizing the denominator:
[tex]\displaystyle \tan\theta=\frac{1}{\sqrt{11}}*\frac{\sqrt{11}}{\sqrt{11}}[/tex]
[tex]\boxed{\displaystyle \tan\theta=\frac{\sqrt{11}}{11}}[/tex]

The snow is now 52 inches deep. If this was a 77% decrease, what was the initial depth? What equation can help you find this?
Answer:
The required equation is:
0.23x = 52
Hence, option A is true.
Step-by-step explanation:
Given
Let 'x' be the initial depth
The snow is now 52 inches deep and it is a 77% decrease.
Let the initial 'x' depth be represented as 100%.
x → 100%
Given the current 52 inches is a 77% decrease. So, we need to decrease the 77/100 or 0.77 from the initial depth, so
[100% - 77%] of x = 52
[100/100 - 77/100] × x = 52
[1 - 0.77] × x = 52
0.23x = 52
Therefore, the required equation is:
0.23x = 52
Hence, option A is true.

Which describes the correlation shown in the scatterplot?
Answer:
Option.B
There is a negative correlation in the data set
The correlation shown in the data is negative correlation.
What is Scatterplots?Scatterplots are the plotting of set of points on a vertical axis and an horizontal axis. The shows the correlation extent between the numbers of the observed quantities.
Positive correlation is defined as the relationship where the value of y increases with the increase in the value of x.
Negative correlation is defined as the relationship where the value of y decreases with the decrease in the value of x.
Here the points are in such a way that the value of y decreases with increase in x.
So it is negative correlation.
Hence the correct answer is negative correlation.

Identify the following series as arithmetic, geometric, both, or neither
[tex]2x + 2 {x}^{2} + 2 {x}^{3} + ... + 2 {x}^{n} [/tex]
Given:
The series is
[tex]2x+2x^2+2x^3+...+2x^n[/tex]
To find:
Whether the given series is arithmetic, geometric, both, or neither.
Solution:
We have,
[tex]2x+2x^2+2x^3+...+2x^n[/tex]
Difference between consecutive terms are:
[tex]d_1=a_2-a_1[/tex]
[tex]d_1=2x^2-2x[/tex]
[tex]d_1=2x(x-1)[/tex]
And,
[tex]d_2=a_3-a_2[/tex]
[tex]d_2=2x^3-2x^2[/tex]
[tex]d_2=2x^2(x-1)[/tex]
Here, [tex]d_1\neq d_2[/tex].
So, the given series is not an arithmetic series.
Ratio between consecutive terms are:
[tex]r_1=\dfrac{a_2}{a_1}[/tex]
[tex]r_1=\dfrac{2x^2}{2x}[/tex]
[tex]r_1=x[/tex]
And,
[tex]r_2=\dfrac{a_3}{a_2}[/tex]
[tex]r_2=\dfrac{2x^3}{2x^2}[/tex]
[tex]r_2=x[/tex]
Similarly upto last pair of consecutive terms.
[tex]r_{n-1}=\dfrac{a_n}{a_{n-1}}[/tex]
[tex]r_{n-1}=\dfrac{2x^n}{2x^{n-1}}[/tex]
[tex]r_{n-1}=x[/tex]
Since, [tex]r_1=r_2=...=r_{n-1}[/tex], so the given series have a common ratio.
Therefore, it is a geometric series.
