Use the equation below to find v, if u=17, a=4, and t=8. 4=u+at
Answer:
This is not a valid equation, as the left-hand side is not equal to the right-hand side.
Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.
Step-by-step explanation:
The given equation is:
4 = u + at
where u = 17, a = 4, and t = 8.
Substituting the given values, we get:
4 = 17 + 4(8)
Simplifying the right-hand side:
4 = 17 + 32
Combining like terms:
4 = 49
This is not a valid equation, as the left-hand side is not equal to the right-hand side.
Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.
The dot plot shows predictions for the winning time in a 200-meter sprint. The winner finished the race in 22.3 seconds. Find the greatest percent error for a prediction to the nearest tenth of a percent. Justify your answer.
The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).
Step-by-step explanation:Given that,
The dot plot shows predictions for the winning time in the 200-meter sprint.
The winner finished the race in 22.5 seconds.
We have to determine,
What is the greatest percent error among the predictions.
According to the question,
The true finishing time is 22.5 seconds.
The prediction furthest from this is 22.9 seconds.
This is a difference of 22.9 - 22.5 = 0.4 seconds.
Divide this over the true time value to get prediction,
0.4/22.5 = 0.0177 = 1.77 (Approximately)
Move the decimal point to the right 2 spots to get to 1.773% (Approximately 1.8%).
Hence, The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).

Answer:
He forgot to flip the second fraction.
Step-by-step explanation:
He has:
−8/9 ÷ 9/8 = −8/9 × 9/8 = −72/72 = −1
He made a mistake. When you change a division to a multiplication, you must use the reciprocal of the second fraction. You have to flipt the second fraction. He did not flip it.
This is correct:
−8/9 ÷ 9/8 = −8/9 × 8/9 = −64/81

How does the decimal point move when 50.2 is multiplied by 1102?
Step-by-step explanation:
50.2 = 5.02 × 10¹
1102 = 1.102 × 10³
so,
50.2 × 1102 = 5.02 × 1.102 × 10³×10¹ =
= 5.02 × 1.102 × 10⁴
so, the decimal point moves 3 positions to the right :

The first table matches with the last equation.
The second table matches with the first equation.
The last table matches with the second equation.
Step-by-step explanation:
What I did was plug in the number in the x section for each table to see if the result of x times the number such as 4 resulted in the same number, y, that was paired with the x number based on the table.
Ex: Using table 1,
y=4x
y=4(2) --> I substituted the x for row 1 x in table 1
y=8
Check:
The first table shows that for row 1, the y was 8 so our match was correct.

Answer:
I'm pretty sure it's 4 units
Answer:
6 square units
Step-by-step explanation:
There are 4 whole squares that we can see very clearly. Next, we have the cut squares. The bigger "cut" square added to the smaller "cut" square is equal to 1 square. There are two cut squares for each side of the trapezoid, but when you add them up they are 1 WHOLE square on each side. 4+1+1=6, therefore the answer is 6 square units.

FOR # 13-#14: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100.
13. Write the inequality and solve the inequality for the number of sales you need to make.
14. Graph your inequality from #13 on a number line.
15. For n(34-n) <111, check whether n = -3 is a solution.
SOLUTION? (Yes or No)______
Answer:
13) x ≥ 50/3
14) see attached graph
15) Yes
Step-by-step explanation:
The equation relating the number of sales and pay is given by
y = 50 + 3x where x is the number of sales.
Q 13
If you need your pay to be exactly 100 then the above equation translates to 50 + 3x = 100
If you want the sales to be at least 100 then the above equation becomes an inequality 50 + 3x ≥ 100
We can re-write this as x ≥ 50/3
Q 14
See attached graph
x = 50/3 is a vertical line passing intersecting the x axis at x = 50/3(16.67)
All values of x ≥ 16.67 forms the region for the inequality
Q 15
Substitute -3 for n in the equation n(34-n) and check whether it satisfies the inequality
(-3)(34 - (-3)) = (-3)(37) is a negative number. (You don't actually have to calculate it but it works out to -111. ) Therefore it satisfies the inequality
n(n-34) < 111 Answer: YES
Answer:
13. x ≥ 50/3

i need help :( can anyone tell me the answer with a explanation?
Let's say the test is 100 points.
The 70% mean means that the mean for the 30 students was 70 points. That means 2100 points were scored between all 30 students. (70·30=2100)
20 boys had a mean of 62% or 62 points for our test. That means the boys earned 62·20 points, or 1240 points.
That then means the girls earned 2100 - 1240 points, or 860 points.
Since there are 10 girls, 860/10 = 86 or 86% mean on the test.
Girls rock!
Use complete sentences to describe why √-1 ≠ -√1
Well let's say that to compare these two numbers, we have to start with the definition first.
Definition
\( \displaystyle \large{ {y}^{2} = x} \\ \displaystyle \large{ y = \pm \sqrt{x} }\)
Looks like we can use any x-values right? Nope.
The value of x only applies to any positive real numbers for one reason.
As we know, any numbers time itself will result in positive. No matter the negative or positive.
Definition II
\( \displaystyle \large{ {a}^{2} = a \times a = |b| }\)
Where b is the result from a×a. Let's see an example.
Examples
\( \displaystyle \large{ {2}^{2} = 2 \times 2 = 4} \\ \displaystyle \large{ {( - 2)}^{2} = ( - 2) \times ( - 2) = | - 4| = 4}\)
So basically, their counterpart or opposite still gives same value.
Then you may have a question, where does √-1 come from?
It comes from this equation:
\( \displaystyle \large{ {y}^{2} = - 1}\)
When we solve the quadratic equation in this like form, we square both sides to get rid of the square.
\( \displaystyle \large{ \sqrt{ {y}^{2} } = \sqrt{ - 1} }\)
Then where does plus-minus come from? It comes from one of Absolute Value propety.
Absolute Value Property I
\( \displaystyle \large{ \sqrt{ {x}^{2} } = |x| }\)
Solving absolute value always gives the plus-minus. Therefore...
\( \displaystyle \large{ y = \pm \sqrt{ - 1} }\)
Then we have the square root of -1 in negative and positive. But something is not right.
As I said, any numbers time itself of numbers squared will only result in positive. So how does the equation of y^2 = -1 make sense? Simple, it doesn't.
Because why would any numbers squared result in negative? Therefore, √-1 does not exist in a real number system.
Then we have another number which is -√1. This one is simple.
It is one of the solution from the equation y^2 = 1.
\( \displaystyle \large{ {y}^{2} = 1} \\ \displaystyle \large{ \sqrt{ {y}^{2} } = \sqrt{1} } \\ \displaystyle \large{ y = \pm \sqrt{1} }\)
We ignore the +√1 but focus on -√1 instead. Of course, we know that numbers squared itself will result in positive. Since 1 is positive then we can say that these solutions exist in real number.
Conclusion
So what is the different? The different between two numbers is that √-1 does not exist in a real number system since any squared numbers only result in positive while -√1 is one of the solution from y^2 = 1 and exists in a real number system.
Answer:
Therefore \(\sqrt{1} \neq -\sqrt{1}\)
Step-by-step explanation:
\(\sqrt{-1} \\\) cannot be calculated as no two identical numbers that are multiplid could give -1. However - \(\sqrt{1}\) means -1 x \(\sqrt{1}\) = -1 x 1 = -1 . Therefore \(\sqrt{1} \neq -\sqrt{1}\)
