2) A 0.4 kg ball moves in horizontal circle of radius 3 mat speed of 100m/s. What
is the centripetal force?
file the
9514 1404 393
Answer:
1333.3 N
Step-by-step explanation:
The centripetal acceleration is given by ...
a = v^2/r
a = (100m/s)^2/(3 m) = (10^4)/3 m/s^2
Then the force on the ball is ...
F = Ma = (0.4 kg)(10^4)/3 kg·m/s^2 ≈ 1333.3 N
(F)x= -4x^2 - 8x - 8 find -3 • f(-1)

Grade is 6th or 7th
Answer:
1 a)8 miles per hour 1 b) 1 hour and 90 minutes 2 a) 24 hours and 6minutes 2 b) 3hours 3 a) 260 hours and 45 minutes 3 b) 40 minutes
Step-by-step explanation:
I don't know for sure if this is all correct but at least you'll have something to write down
Answer:
1a. 8 miles per hour
1b. 32 km per hour
2a. 28 miles
2b. 3 hours
3a. 2925
3b. 1/4 hour or 15 minutes
Step-by-step explanation:
For number 1a, think of 2 1/2 hours equals 20 miles as 2 1/2x=20. The x being hours, and the 20 being 20 miles. You want the equation to become x=?. So you divide 2 1/2x=20 by 2 1/2 to make the equation start with x=. You end up with x=8. Or you could just think of it as divide 20 miles by 2 1/2 hours. Either way, you end up with 8 miles per hour. For number 1b, you do the same thing as before, but you have to make 4 hours and 45 minutes a fraction. So, the are 60 minutes in an hour, so the fraction would be 45/60. Then you simplify that down to 3/4. So, 152 km divided by 4 3/4 is 32 km per hour.
For number 2a, set aside 30 minutes for now. She can go 24 miles in 3 hours. Because 8 miles times 3 hours equals 24 miles. It’s like instrad of 8 miles per hour, it’s 24 miles per 3 hours. Then, because 30 minutes is half of an hour, 8 divided by 2 would make it 4 miles per half an hour. So 24 plus 4 is 28 miles. For number 2b, you want to know how many hours it took to travel 1980 miles. Since you already knowmthat is takes one hour to go 660 miles, pretend that each 660 miles is one hour. So you divide 1980 by 660 so see how many one hours fit. You get 3. So, an airplane can fly 1980 miles in 3 hours.
For number 3a, like 2a, you basically multiply the constant speed by the full hours then the fraction, and add them together. You could also just multiply the constant speed by the number 3 3/4. That way you get the miles per 3 3/4 hours. 3 3/4 times 780 is 2925. So the plane can fly 2925. For number 3b, to get the 2 miles per ? hours, you have to divde 8 by 4 to get to 2. So you divide 1 hour by 4 to get the answer. So it’s 1/4, (one fourth of an hour) or 15 minutes 1/4 of 60 (the amount of minutes in an hour) for Mary to go 2 miles.

Jonathan went shopping for a new pair of pants. Sales tax where he lives is 4.75%. The price of the pair of pants is $20. Find the total price including tax. Round to the nearest cent.
Answer:
20.95$
Step-by-step explanation:
To find the total price we need to find 4.75% of the 20 and to do that we need to multply 20 with 4.75 and divide it by 100
20 × 4.75 ÷ 100 = 0.95
20$ + 0.95$ = 20.95$
if -2x + 3 = 7 and 3x + 1 = 5 + y, the value of y is
Answer:
value of y is -10
Step-by-step explanation:
-2x+3=7 equation 1
3x+1=5+y equation 2
by eq 1
-2x=7-3
-2x=4
x=-2
put value of x in equation 2 to get value of y
3(-2)+1=5+y
-6+1=5+y
-5=5+y
-5-5=y
y=-10

interest earned on both the principal and any previously earned interest?
a. compound interest
b. simple interest
c. interest rate
d. principal
Answer:
A. Compound Interest
Step-by-step explanation:
Compound interest is interest paid on both the principal and previously earned interest.
Compound interest earned on both the principal and any previously earned interest. Therefore, the correct answer is option A.
What is the rate of interest?An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.
Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex]
Therefore, option A is the correct answer.

Austin keeps a right conical basin for the birds in his garden as represented in the diagram. The basin is 40 centimeters deep, and the angle
between the sloping sides is 77º. What is the shortest distance between the tip of the cone and its rim?
A. 177.8 cm
B. 64.3 cm
C. 50.3 cm
D. 51.1 cm
E. 41.1 cm
Answer:
Option D. 51.1 cm
Step-by-step explanation:
Please see attached photo for explanation.
In the attached photo, c is the distance between the tip of the cone and its rim.
The value of c can be obtained as follow:
Angle θ = 38.5°
Adjacent = WY = 40 cm
Hypothenus = WZ = c =?
Cos θ = Adjacent / Hypothenus
Cos 38.5 = 40 / c
0.7826 = 40 / c
Cross multiply
0.7826 × c = 40
Divide both side by 0.7826
c = 40 / 0.7826
c = 51.1 cm
Thus, the distance between the tip of the cone and its rim is 51.1 cm.
Answer:
Option D. 51.1 centimeters
