Which conversions from scientific notation to standard notation are true? Check all that apply.
Answers
The correct conversion from scientific notation to standard notation are:
b) [tex]8.05\times 10^5[/tex]
e) [tex]7.09\times 10^{-6}[/tex]
Step-by-step explanation:We know that when we have a power of 10 as positive then the decimal is shifted to the right and if the power of 10 is negative then we shift the decimal to the left.
a)
[tex]1.71\times 10^3[/tex]
As the power of 10 is positive hence we shift the decimal to the right 3 places.
Hence, the conversion is:
[tex]1.71\times 10^3=1710[/tex]
b)
[tex]8.05\times 10^5[/tex]
Again the power of 10 is positive and hence we will shift the decimal 5 places to the right and the conversion is done as follows:
[tex]8.05\times 10^5=805000[/tex]
c)
[tex]2.4\times 10^4[/tex]
Since, the power of 10 is positive and hence we will shift the decimal 4 places to the right and we convert the number to standard notation as:
[tex]2.4\times 10^4=24000[/tex]
d)
[tex]8.25\times 10^{-3}[/tex]
Since, the power of 10 is negative and hence we will shift the decimal 3 places to the left and we convert the number to standard notation as:
[tex]8.25\times 10^{-3}=0.00825[/tex]
e)
[tex]7.09\times 10^{-6}[/tex]
Since, the power of 10 is negative and hence we will shift the decimal 8 places to the left.
Hence, we convert our number to standard notation:
[tex]7.09\times 10^{-8}=0.00000709[/tex]
It is accurate to convert scientific notation to standard notation in the following ways:
B [tex]8.05x10^5=805,000[/tex]
C [tex]2.4x10^4= -24,000[/tex]
E [tex]7.09x10^-^6=0.0000070[/tex]
To solve this problemFirstly, Let's evaluate each conversion one by one:
[tex]1.71x 10^3=0.00171[/tex]
This conversion is not true. The correct value of[tex]1.71x 10^3[/tex] is 1710.
[tex]8.05x10^5=805,000[/tex]
This conversion is true.
[tex]2.4x10^4= -24,000[/tex]
This conversion is true.
[tex]8.25x10^-^3=-8,250[/tex]
This conversion is not true. The correct value of [tex]8.25x 10^-^3[/tex] is 0.00825.
[tex]7.09x10^-^6=0.0000070[/tex]
This conversion is true.

Answer:
False
The correct point slope form passing through points (x1,y1) is [tex](y-y1)=m (x-x1)[/tex] .
Step-by-step explanation:
The formula for the point slope form passing through the point (a,b) is given by.
[tex](y-b)=m (x-a)[/tex]
Where m is the slope .
As given in the question.
m is the slope and (x1, y1) is a point on the line.
Thus the point slope form becomes
[tex](y-y1)=m (x-x1)[/tex]
Therefore the correct point slope form passing through points (x1,y1) is [tex](y-y1)=m (x-x1)[/tex] .

What is Expression?An expression is combination of variables, numbers and operators.
Given,
The baker pays $0.80 per pound for sugar
The baker pays $1.25 per pound for butter.
We need to write expression that shows how much the baker will spend if he buys 6 pounds of butter and 20 pounds of sugar.
Let x be the pounds for sugar
x be the pounds for butter
20x+6y=Total
As x=0.80 and y=1.25
20(0.80)+6(1.25)
16+7.5
23.5
Hence, the total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.

Consider the following sets. U = {ordered pairs on a coordinate plane} A = {ordered pair solutions to y = x} B = {ordered pair solutions to y = 2x} Which ordered pair satisfies A ∩ B?
Answers
Answer:
(0,0)
Step-by-step explanation:
We have,
U = { (x,y) : x,y belong to real numbers }
A = { (x,y) : (x,y) is a solution of y=x }
B = { (x,y) : (x,y) is a solution of y=2x }
We need to find the ordered pair (x,y) that belong to A[tex]\bigcap[/tex]B.
Let, (x,y) belong to A[tex]\bigcap[/tex]B
i.e. (x,y) belong to A and (x,y) belong to B
i.e. y = x and y = 2x
i.e. x = 2x
i.e. x = 0
Now, substitute x= 0 in any of the equation say y = x, we get y = 0.
Hence, the ordered pair satisfying A[tex]\bigcap[/tex]B is (0,0).
For a set U, The ordered pair satisfies A ∩ B is mathematically given as
x = 0, y = 0 (0,0)
Which ordered pair satisfies A ∩ B?Question Parameter(s):
U = {ordered pairs on a coordinate plane}
A = {ordered pair solutions to y = x}
B = {ordered pair solutions to y = 2x}
if (x,y) belongs to AnB
y = x and y = 2x
x = 0
In conclusion, subsituting we have
y = x and y = 2x
y = 0

The highest score that is a record for a particular video game is 19,749 points. The lowest score on record for the same video game is 176 points. Which of the following inequalities best shows the range of scores recorded on the game?
Answers
They key is the less than or equal to sign.
Have a blessed day :)
The highest score that is a record for a particular video game is 19,749 points, and it means that the individual could get 19749 points or lower than that, so the inequality will be like this:
[tex]x \leq 19749[/tex]
Next, the lowest score on record for the same video game is 176 points, and it also means that the individual could get 176 points or lower, so the inequality will be:
[tex]x \geq 176[/tex].
Finally, we have the two inequality we want and let's combine them, to get:
[tex]176 \leq x \leq 19749[/tex]. As a result, D is your final answer. Hope it help!

What is the equation of the line that is parallel to y = -2x + 4 and goes through the point (1,7)
Answers
-----------------------
Work Shown:
The slope of the line y = -2x+4 is m = -2
Any line parallel to this line will also have a slope of m = -2
Parallel lines have equal slopes
Plug this slope, along with the given point (x1,y1) = (1,7) into the point slope formula. Then isolate y
y - y1 = m(x - x1)
y - 7 = -2(x - 1)
y - 7 = -2x + 2
y - 7 + 7 = -2x + 2 + 7
y = -2x + 9

A ladder that is 14 feet long is placed against a building. The bottom of the ladder is 6 feet from the base of the building.
In feet, how high up the side of the building is the top of the ladder? Round to the nearest tenth of a foot
Answers
c^2 = a^2 + b^2, where c is the hypotenuse, a and b are the other shorter legs. Substituting the values,
14^2 = 6^2 + x^2
x^2 = 14^2 - 6^2
x^2 = 160
x = 4√10 = 12.65 feet
The height of the building from the top of the ladder is 12.6 ft
The situation forms a right angle triangle.
Right angle triangle:A right angle triangle is a triangle that has one of its sides as 90 degrees.
Therefore,
The length of the ladder is the hypotenuse side.
The bottom of the ladder distance from the base of the building is the adjacent side of the triangle. Therefore,
The height of the building from the top of the ladder is the opposite sides. Therefore, using Pythagoras theorem.
c² = a² + b²
14² - 6² = b²
b² = 196 - 36
b² = 160
b = √160
b = 12.6491106407
b = 12.6 ft

An arrow is shot upward with a velocity of 64 feet per second. Using the formula h(t)=64t-16t^2, how long after the arrow is released does it hit the ground?
Answers
-16t^2+64t=0 factor
-16t(t-4)=0, we know t>0 so
t=4 seconds.
Answer:
After the 4 second arrow is released, it will hit the ground.
Step-by-step explanation:
Consider the provided formula.
[tex]h(t)=64t-16t^2[/tex]
We need to find how long after the arrow is released does it hit the ground.
If the arrow hit the ground that means the value of h(t)=0.
Substitute the value of h(t)=0 and solve the equation as shown.
[tex]64t-16t^2=0[/tex]
[tex]16t(4-t)=0[/tex]
Now use zero product rule: If ab=0 then either a=0 or b=0
[tex]16t=0\ or\ 4-t=0[/tex]
[tex]t=0\ or\ -t=-4[/tex]
[tex]t=0\ or\ t=4[/tex]
Hence, after the 4 second arrow is released, it will hit the ground.

I draw a card 50 times from a standard 52 deck and gets a heart 8 times what's the probability that I draw a heart on the next draw
Answers
To solve this problem, let us first define what probability is. By standard definition, probability is the ratio of how many times a selected event occurred over the total number of events which occurred. Hence:
Probability = number of times a selected event occurred / total number of events
In this case, our selected event is the drawing of a heart which occurred 8 times. While our total event is the total number of drawing of cards which occurred 50 times. Hence, the probability is:
Probability = 8 / 50
Probability = 4 / 25 = 0.16 = 16%
Therefore there is a 4/25 or 0.16 or 16% chance that the next draw will be a heart.
