Write in the simplified form, and show steps, please!!!!
Answer:
(2^8 ⋅ 5^−5 ⋅ 19^0)^−2 ⋅ (5^-2/2^3)^4 ⋅ 2^28
= (2^-16 ⋅ 5^10 ⋅ 1)⋅(5^-8 / 2^12) ⋅ 2^28
= 2^(-16-12+28) ⋅ 5^(10-8)

Answer:
sin135° = [tex]\frac{1}{\sqrt{2} }[/tex]
Step-by-step explanation:
135° is in the second quadrant where sin x ° > 0
sin135°
= sin(180 - 135)°
= sin45°
= [tex]\frac{1}{\sqrt{2} }[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ← exact value

Suppose n-15 is a whole number. What do you know about the value of n? Explain
Answer:
N is an integer
Step-by-step explanation:
Answer:
n = 15
Step-by-step explanation:
Solve for n:
n - 15 = 0
Hint: | Isolate terms with n to the left hand side.
Add 15 to both sides:
n + (15 - 15) = 15
Hint: | Look for the difference of two identical terms.
15 - 15 = 0:
Answer: n = 15

Step 2: Divide both sides by 4.
4x /4 = −45 /4

6 - 3/4x + 1/3 = 1/2x + 5
help
Answer:
x=15/16
Step-by-step explanation:
Let's solve your equation step-by-step.
6−34x+13=12x+5
6+−34x+13=12x+5
Multiply all terms by x and cancel:
6x+−34+1x3=12+5x
193x+−34=5x+12(Simplify both sides of the equation)
193x+−34−5x=5x+12−5x(Subtract 5x from both sides)
43x+−34=12
43x+−34+34=12+34(Add 3/4 to both sides)
43x=54
(34)*(43x)=(34)*(54)(Multiply both sides by 3/4)
x=1516
Check answers. (Plug them in to make sure they work.)
x=1516(Works in original equation)

d.
Each vertical line drawn through the graph will intersect a function in only one location
I'm having a hard time understanding this.
Answer:
Hello,
I am not sure if you are still having an issue with this problem but for future reference for you or anyone else the answer is
d. Each vertical line drawn through the graph will intersect a function in only one location.
I thought of it this way:
"Each vertical line" which tells me only one line per "one location" now I could be completely off but this was just my logic and it helped me personally.

Five less than twice a number is equivalent to 47
Answer:
2x - 5 = 47 is the expression .
x = 26
Step-by-step explanation:
The number is 26.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values. We frequently observe constant change in
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
given:
Five less than twice a number is equivalent to 47
let the number is x
So, 2x- 5= 47
Now solving for x
2x- 5= 47
2x= 52
x= 26
Hence, the number is 26

Which of the following expressions is correct?
-(-21) = 21
-(-21) = -21
-(21) = 21
(-21) = 21
Answer:
The correct answer is: [A]: " -(-21) = 21 " .
________________________________
Step-by-step explanation:
________________________________
Let us examine the answer choices given.
________________________________
Choice: [A]: " -(-21) = 21 . This is correct;
→ since a "negative value of negative value" is a "positive value" ; as shown in this case. The equal sign holds true, since the
"negative of a "negative value" is equal to the "positive value" of that same "positive value equivalent."
________________________________
Choice: [B]: " -(-21) = -21 . This is incorrect. As explained above:
→ a "negative of negative" is a "positive value" .
This answer choice shows that a "negative of negative"; is a "negative" :
→ which is: INCORRECT.
→ Rule out: "Choice: [B]."
________________________________
Choice: [C]: " -(21) = 21 . This is incorrect. The "negative" value [of a positive integer is not equal to the "equivalent positive value" of that same integer.
→ Rule out: "Choice: [C]."
________________________________
Choice: [D]: " (-21) = 21 "; This is incorrect. In a conceptually similar way as explained above—(for "Answer Choice: [C]" — the "negative value equivalent" of an integer is NOT equal to the "equivalent positive value" [of that same integer.].
→ Rule out: "Choice: [D]."

A hiker climbs a mountain. After 1 hour he is at an altitude of 200 feet. After 3 hours, he is at an altitude of 350 feet. What is the rate of change?
Answer: 75 feet per hour
Step-by-step explanation:
X: 1, 3
Y: 200, 350
150/2
75
The rate of change in altitude is 75 feet per hour.
What is rate?Rate is a measurement to determine the change in one quantity with respect to another quantity.
Given that,
Altitude of hiker after 1 hour = 200 feet
Altitude of hiker after 3 hours = 350 feet
The change in altitude = 350-200 = 150 feet
The difference of time = 3 - 1 = 2 hours
Rate of change = change in altitude/ change is time
= 150/2
= 75 feet per hour
The rate of change in altitude of the hiker is 75 feet per hour.

What is the equation of a line perpendicular to y=1/4x−3 and passes through the point (−2, 4)?
Answer:
y = -4x - 4Step-by-step explanation:
Given line
y = 1/4x - 3Perpendicular line has a slope that is negative reciprocal to a given
y = - 4x + b is the equation,Finding the value of b using the point (-2, 4)
4 = -4*(-2) + b4 = 8 + bb = -4So the line is:
y = -4x - 4Answer:
y = -4x - 4
Step-by-step explanation:
The line of a perpendicular line is the opposite reciprocal of the original line.
1/4 -> -4/1 -> -4
Now that we have the new slope, we can find the new y-intercept.
y = -4x + b
4 = -4(-2) + b
4 = 8 + b
-4 = b
y = -4x - 4

6. A tank contains 100-gallon of pure water. At time t = 0, a solution containing 2 lb of salt per gallon flows into the tank at a rate of 3 gallons per minute, and the well-stirred mixture flows out at a rate of 4 gallons per minute. Find the amount (in lb) of salt Q in the solution as a function of t in minutes.
Answer:
The answer is below
Step-by-step explanation:
Let Q represent the amount of salt in the tank at time t.
[tex]\frac{dQ}{dt}= flow\ in - flow\ out\\ \\flow\ in=3\ gal/min*2\ lb/gal=6\ lb/min\\\\net\ gain\ in\ tank\ volume=3-4=-1, henceflow\ out= \frac{4Q}{100-t} \\\\\frac{dQ}{dt}= 6-\frac{4Q}{100-t} \\\\\frac{dQ}{dt}+ \frac{4Q}{100-t}=6\\\\The \ integrating\ factor\ is:\\\\IF=e^{\int\limits {\frac{4}{100-t} } \, dt }=e^{-4\int\limits {\frac{-1}{100-t}}=e^{-4ln(100-t)}=(100-t)^{-4}}\\\\Multiplying\ through \ by\ IF: \\\\(100-t)^{-4}\frac{dQ}{dt}+ (100-t)^{-4}\frac{4Q}{100-t}=6(100-t)^{-4}\\\\[/tex]
