Answer:
Acceleration equals zero because of constant velocity
[tex]f - fr = ma \\ 70 \cos(30) - fr = 0 \\ 70 \cos(30) = fr \\ fr \: = 60.62[/tex]

I walk each day to school. By what percentage would I need to increase my usual average speed in order for the journey to take 20% less time than usual? C:
Answers
Answer:
25%
Step-by-step explanation:
Let v, t be the current average speed and the time taken to reach the school respectively.
As distance = speed x time, so,
distance, d=vt...(i)
Let V be the new average speed in order to to take 20% less time than t.
So, time taken with speed V = t-20% of t = t- 0.2t= 0.8t
As distance is constant, so
d= V(0.8t)= 0.8Vt
hBy using equation (i), we have
0.8Vt = vt
0.8 V = v
V= v/0.8=1.25v
Therefore, the percentage increase in the average speed = [tex]\frac{V-v}{v}\times 100[/tex]
[tex]=\frac{1.25v-v}{v}\times 100[/tex]
=25%
Hence, the percentage increase in the average speed is 25%.

Answers
Answer:
Mean: 7
Median: 8
Range: 9
Mode: 3
Step-by-step explanation:
First, to find the mean of a set of numbers you need to add up all of the numbers and divide that by the total amount of numbers. In this case that makes this equation, [tex]\frac{3+3+4+8+9+10+12}{7}[/tex], which is [tex]\frac{49}{7}[/tex], which is 7.
To find a median you need to find the middle number. A handy trick I use for this is to place my fingers on the first and last number, and then move them towards the middle, at the same time by one number until there is just one number left in the middle. If there are no numbers left after doing this, meaning there are an even amount of numbers given, the median is the mean of the last two numbers that were covered. In this case, this is not necessary, so the median is 8.
The range is the difference between the maximum and minimum of a data set. In this case that would give you the equation Range=12-3, which means the range is 9.
Finally, the mode is the number that occurs the most in a given data set. In this case the number that occurs the most is 3, which occurs twice compared to every other number which only occurs once.
Hey there!
‘‘Find the mean median range and mode for 3, 3, 4, 8, 9, 10, and 12’’
• Mean is known as your AVERAGE number. You have to ADD all of your NUMBERS the DIVIDE it by the TOTAL numbers in your given set
• We have the total of SEVEN numbers in your set
“3 + 3 + 4 + 8 + 9 + 10 + 12 / 7”
6 + 4 + 8 + 9 + 10 + 12/7
10 + 8 + 9 + 10 + 12/7
18 + 9 + 10 + 12/7
27 + 10 + 12/
37 + 12/7
49/7 = 7
Answer: Mean = 7 ✔️
• Median is the number you see in the center (the middle) of the problem. You can solve for this by putting your numbers from least to greatest
• If you have an ODD number in your given set then your middle number will be the single number)
• If you have an EVEN number then you have to average your TWO middle number
“ 3, 3, 4, 8, 9, 10, 12”
• you still have 3 on both sides of your 8 (3 is an ODD number, so we have to let it be be a single number)
Answer: mean = 8 ✔️
• Mode is your number than you see repeated OR more than once
• We “3” repeated so it is your Mode
Answer: Mode = 3 ✔️

Answers
Answer:

Step-by-step explanation:
just took the test edg 22
Option B is correct, -5.5 is the zero of the quadratic function f(x) = 4x + 24x + 11
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given quadratic function is f(x) = 4x²+24x+11
We have to find the zero of the function.
Let us use the quadratic formula to find the zero.
a=4, b=24 and c=11
Let us plug in these values in quadratic formula
x=- 24±√24²-4(4)(11)/8
=-24±√576-176/8
=-24±√400/8
=-24±20/8
=4(-6±5)/8
=(-6+5)/2 or -6-5/2
=-1/2 or -11/2
=-0.5 or -5.5
Hence, Option B is correct, -5.5 is the zero of the quadratic function f(x) = 4x + 24x + 11

If you deposit 4,300 into an account with an semi annual interest rate of 11% how much will you have after 1year
Answers
Answer:
FV= $4,786.01
Step-by-step explanation:
Giving the following information:
Initial deposit (FV)= $4,300
Number of periods (n)= 2 semesters
First, we need to calculate the semi-annual interest rate:
Semi-annual interest rate= 0.11/2= 0.055
Now, to determine the future value, we need to use the following formula:
FV= PV*(1+i)^n
FV= 4,300*(1.055^2)
FV= $4,786.01

Answers
Answer:
6 erasers
Step-by-step explanation:
The pencils and the notebook together cost $2.75, from there you can calculate how many erasers.
1 eraser would bring the total to $3, therefore Denise can buy $1.25 more of erasers which is 5. 3 + 1.25 is $4.25. therefore Denise can buy 6 erasers
Answer:
he can buy 6 erasers
Step-by-step explanation:
because if you add 1.75 plus one and add 0.25 ....6 times it will equal 4.25 i hope this was helpful
