Step-by-step explanation:
The correct order of the given expressions is:
1: (1.93 x 10⁷) - (9.7 x 10⁶)
3: (1.93 x 10⁷) - (0.97 x 10⁷)
6: (1.93 - 0.97) x 10⁷
2: 0.96 x 10⁷
4: 10/10 (0.96 x 10⁷)
7: (1.93 x 10⁷) - 10/10 (9.7 x 10⁶)
8: 9.6 x 10⁶
What is an expression?In mathematics, an expression is a combination of one or more numbers, variables, and mathematical operations that can be evaluated to produce a value or result.
The correct order to perform the subtraction operation is:
Write out the problem: (1.93 x 10⁷) - (9.7 x 10⁶)
Subtract the second number from the first number (ignoring the scientific notation): (1.93 - 0.97) x 10⁷
Simplify the subtraction to get the result in scientific notation: 0.96 x 10⁷. Convert the result to standard scientific notation: 9.6 x 10⁶.

A cyclist rolls down a hill. He starts from rest and after 8 s he is traveling at 13.6m/s. What is his acceleration?
Answer:
1.7 m/s^2
Step-by-step explanation
acceleration is change in velocity / time
so we do 13.6 - 0 = 13.6 gives us change in velocity
13.6/8 = 1.7 m/s^2 gives acceleration

The fight time from Boston to London is 6 hours 20 minutes
London at 4:05pm. What time did I set off from Boston?
Answer:
9:45am.
Step-by-step explanation:
In 6 Hours and 20 minutes, there's 380 minutes.
Because 60 x 6 + 20 =380
So you go back 380 minutes from 4:05.
4:05pm minus 380minutes= 9:45am.
The time did I set off from Boston is 9:45 am.
Given that,
The fight time from Boston to London is 6 hours 20 minutes London at 4:05pm.Based on the above information, the calculation is as follows:
In 6 Hours and 20 minutes, there should be380 minutes.
As [tex]60 \times 6 + 20 =380[/tex]
So it should be like
= 4:05 Pm - 380 minutes
= 9:45 am

Which function g represents the exponential function f(x) = 5x after a vertical stretch by a factor of 2 and a reflection across the x-axis?
A. g(x) = (2 ⋅ 5)−x B. g(x) = −(2 ⋅ 5)x C. g(x) = 2 ⋅ (5)−x D. g(x) = −2 ⋅ (5)x
Answer:
g(x) = -2 • 5^x
Step-by-step explanation:
the reflection across the x-axis makes the equation negative. the 2 is the verticals stretch.
(also got the answer correct on a test)
The function f(x) after a vertical stretch by a factor of 2 and a reflection across the x-axis becomes [tex]\rm g(x) =-2\times (5)^x[/tex] and this can be determined by using the rules of transformation.
Given :
[tex]\rm f(x) = 5^x[/tex]
The following steps can be used in order to determine the function after the given transformation:
Step 1 - The rules of transformation can be used in order to determine the function after the given transformation.
Step 2 - Write the given function.
[tex]\rm f(x) = 5^x[/tex]
Step 3 - Now, stretch the graph of the above function vertically by a factor of 2. So, the function of the graph obtained is:
[tex]\rm h(x) =2\times (5)^x[/tex]
Step 4 - Now, take the reflection of the graph obtained in the above step about the x-axis. So, the function of the graph obtained is:
[tex]\rm g(x) =-2\times (5)^x[/tex]
Therefore, the correct option is D).

Answer:
F; A translation of 6 up and 4 left and a reflection across the x-axis
Step-by-step explanation:
Here, we want to perform the translation that would move S to S’
to do this, we can have a subtraction
For 1 to move to -3 on the x-axis;
it means there is a leftward shift of upto 4 units
For -8 to turn to 2;
this is positive; there is a vertical upward translation of upto 10 units on the y-axis
This option is not directly available; thus we have to factor the reflection
if we reflect on the x-axis, the y-axis value becomes negated; if we reflect on the y-axis, the x-value becomes negated
The correct answer is thus;
A translation of 6 up and 4 left, followed by a reflection across the x-axis

The ratio of the income to the savings of a family is 15 :4 find the expenditure if the saving is Rs 2800.
Answer:
= 7700
Step-by-step explanation:
income : savings = 15 : 4
income = 15x
savings = 4x
but it is given that savings = 2800
therefore
4x = 2800
x = 700
income = 15x
= 15*700
= 10500
expenditure = income - savings
= 10500-2800
= 7700

Answer:
The fraction ate is 2/3
Step-by-step explanation:
Here, we want to get the fraction of the total ate
From the question, Joe ate 3 out of 12 pieces;
That would be 3/12
same ate 5 out of 12, that will be 5/12
So the fraction ate will be;
3/12 + 5/12 = 8/12 = 2/3

Step-by-step explanation:
The measure of an arc is equal to the angle at the centre subtended by the arc.
The sum of the 3 arcs = 180° , then
5x + 6 + 83 + 51 = 180
5x + 140 = 180 ( subtract 140 from both sides )
5x = 40 ( divide both sides by 5 )

Step-by-step explanation: Ms.Li spent $840 on vacation, She spent 2/3 of the amount on a train ticket and 1/2 of the remaining amount on food. How much did she spend on ticket and food altogether= 840 2/3 = 560
840-560 = 280
half of 280 = 140

Answer:
90 Degrees
Step-by-step explanation:
This is a very cool theorem. When the longest side of a triangle is the diameter of the circle, which in the picture you can see it is, the angle opposite to it is ALWAYS 90 degrees. Remember that the points have to be on the circle for this theoroem to work. I forget what the theoroems is called, but it is very helpful.
Thanks and have a great day!
