Answer:
6.29 × 10^-5
Step-by-step explanation:
0.0000629
The number part of the answer is 6.29
To go from 0.0000629 to 6.29, the decimal point needs to move 5 places to the right, so the exponent on the 10 must be -5.
0.0000629 = 6.29 × 10^-5
Answer: 6.29*10^(-5)
Step-by-step explanation:
0.0000629=
0.629*10^(-4)= ==> there are 4 zeros before the decimal point.
6.29*10^(-(4+1))=6.29*10^(-5)
On the coordinate plane, the segment from U(4, -6) to V(-8, -11) forms one side of a
rectangle. The rectangle has a perimeter of 78 units. Find the area of the rectangle.
Write your answer as a whole number, decimal, or simplified radical. Do not round.
___ square units
pls help me
The area of the rectangle = 338 square units
The co-ordinate plane has two axes X and Y.
The points in the co-ordinate plane is given as U(4, -6) to V(-8, -11).
i.e., (x₁, y₁) = (4, -6) and (x₂, y₂) = (-8, -11)
The distance between these points are considered as a side of a rectangle.
Distance between U(4, -6) and V(-8, -11) = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
= [tex]\sqrt{(-8-4)^2+(-11--6)^2}[/tex]
= [tex]\sqrt{(-12)^2+(-5)^2}[/tex]
= √169
= 13 units
So the length of one side of rectangle, l = 13 units
Let 'w' be the width of the rectangle.
Also perimeter of the rectangle = 78 units
⇒ 2(l +w) = 78
⇒ l +w = 39
⇒ w = 39 -l
⇒ w = 39 - 13
⇒ w = 26 units
Area of the rectangle = length x width
= l x w
= 13 x 26
= 338 square units

x ≤ 9 x > 1What is meant by the rational inequality?A rational inequality is one that includes a rational expression.
To solve a rational inequality, first locate the zeroes (from the denominator) and also the undefined points (from the denominator). These zeroes and undefined points are used to divide this same number line into intervals. Then you locate the rational's sign on each interval.1. (3x - 1)/(x + 4) ≤ 2
Solving the equation.
3x - 1 ≤ 2(x + 4)
3x - 1 ≤ 2x + 8
Placing the constants and the variable on different side.
3x - 2x ≤ 8 + 1
x ≤ 9
Thus, the value of 'x' is less than equal to 9.
2. 2x/(x + 1) > 1
Simplifying;

The graph above shows the graphs of the cost (in green) and revenue (in blue) functions for a company that manufactures and sells small radios.
a) How many radios must be produced and sold to break even?
Answer:
b) What is the dollar amount coming in and going out if the company just breaks even?
Answer:
c) Use the formulas to write the company's profit function, (), from producing and selling radios.
(Notice in this problem, you must enter the entire function, not just the right hand side)
Answer:
d) How much profit will the company earn if it produces and sells 500 radios?
Answer:
The company must sell 400 radios to break even, i.e, when the revenue function and cost function is same.
The sum of the units sold times the price per unit is the revenue. Multiply the output level by the pricing function to get the revenue function.
The cost function is the total cost of production of the item which includes the cost of raw materials, labor, transport and establishment costs.
The cost function and the revenue function is given as:
Cost function is C(x) =5000 + 7.5x
And the revenue function is R(x) = 20x
a)In the break even point cost will be equal to revenue
so, C(x)=R(x)
or,5000+7.5x=20x
or,12.5x=5000
or, x=5000÷12.5
or, x=400
The number of radios produced to break even is 400.
(b)When the company breaks even then x=400
∴R(200)=200×20=8000
So the amount of money is dollars that is coming in or going out is given by 8000.
(c)We know that the profit=Revenue - cost
So the required profit function is given by:
p(x)=R(x)-C(x)
or, p(x)=20x-5000-7.5x
or,p(x)=12.5x-5000
(d)The company sells 500 radios
Therefore profit will be given by
p(500)=12.5×500-5000
or,p(500)=6250-5000
or, p(500)=1250
So on selling 500 radios the company will earn $1875.
Disclaimer: The revenue and cost function of the equation are
C(x) =5000 + 7.5x and R(x) = 20x .

Joel noticed that when he runs, his heart begins to beat rapidly. Joe wants to do an experiment to see if his heart beats faster the longer he runs. Which is the best design for Joel‘s experiment?
a. Joel should get a group of people to run. Then he should ask them what their heart rates were after one minute.
b. Joe should ask someone to run at one speed. Then he should run the same amount of time at another speed.
c. Joel should run at a constant speed and measure his heart rate after different amounts of time has passed.
d. Joel should run different amounts of time at many different speeds and measured the heart rate during each run.
Answer:
C
Step-by-step explanation:
We can go through the process of elimination to solve the question.
A is incorrect because they are only running for a minute and the variation between time and heart rate cannot be measured.
B is incorrect because there are too many variables to account for and they are both running for the same amount of time.
D is incorrect because there are too many variables to account for and it is not a fair test as he is running at many different speeds (you can only change the independent variable which is the time).
Hence, C is the answer. It is a fair test as he is running at different speeds and keeping everything else the same.

4.) Connor went to the fair with $22. He bought a hot dog and a coke for $5 and planned to spend the rest of his money on rides that cost $1.50 each. Write and solve an inequality to represent the number of rides that Connor can afford.
The inequality represents the number of rides that Connor can afford is 1.50x+5≤22 and he can ride 11 rides
The amount Connor had when he went to the fair = $22
The cost of a hotdog and coke = $5
The cost of each ride = $1.50
Consider then number of rides he ride as x
Then, the equation of the inequality is
1.50x+5≤ 22
Solve the inequality
1.50x+5≤ 22
1.50x ≤ 17
x ≤ 11.33
He can afford 11 rides with the money he has
Hence, the inequality represents the number of rides that Connor can afford is 1.50x+5≤22 and he can ride 11 rides

You deposit money in an account that earns simple
interest at an annual rate of 6%. After 8
years, the account earns $360 in interest. How much money did you deposit in the account?
By writing an exponential equation, we can conclude that the initial deposit is of $606.22
How much money did you deposit in the account?Here we know that we have an annual rate of 6%, so if you deposit an initial amount of A, the amount of money that the account has after t years is:
M(t) = A*(1 + 6%/100%)^t = A*(1.06)^t
Now, you know that after 8 years you earn (in interest) $360, then we can write:
M(8) - A = 360
A*(1.06)^8 - A = 360
Now we can solve that equation for A.
A*( (1.06)^8 - 1) = 360
A = 360/( (1.06)^8 - 1) = 606.22
The initial deposit is of $606.22

Answer:
Step-by-step explanation:
Simplifying
3 + -4x = 23
Solving
3 + -4x = 23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -4x = 23 + -3
Combine like terms: 3 + -3 = 0
0 + -4x = 23 + -3
-4x = 23 + -3
Combine like terms: 23 + -3 = 20
-4x = 20
Divide each side by '-4'.
x = -5

Find the distance between two points.
P(5\sqrt{x} 3,7\sqrt{x} 5),Q(\sqrt{x} 3,-\sqrt{x} 5)
The distance between the two points is approximately 19.18 units
The length of the line segment connecting any two points is referred to as their distance. In coordinate geometry, the distance formula is usedto calculate the distance between two points.
In 1731, the distance formula itself was first made public. Pythagorean distance is another name for Euclidean distance. The Pythagoras is used to derive the distance formula.
If two point are given as A [tex](x_1,y_1)[/tex] and B [tex](x_2,y_2)[/tex] then the distance between the two points or the length of AB is calculated using the formula:
[tex]AB = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]
The co ordinates of the two points are given as [tex](5\sqrt{3},7\sqrt5 )[/tex] and [tex](-\sqrt{3},-\sqrt{5} )[/tex].
Therefore distance between the points will be given by:
[tex]=\sqrt{(5\sqrt{3} - \sqrt{3} )^2 + (7\sqrt{5} -(-\sqrt{5} )^2}\\=\sqrt{(4\sqrt{3})^2+(8\sqrt{5})^2 }\\=\sqrt{48+320}\\=\sqrt{368}\\\approx19.18[/tex]
