Mary throws a plastic disc to her friend, which her friend catches six seconds after Mary throws it. The table shows the height of the disc at one-second intervals. Assuming that the throw represents projectile motion, what are the missing values in the table?

Answers

Answer 1
Answer: Unfortunately, there is no given table. However, assuming no air resistance, the projectile moves in constant acceleration in the y-axis, while constant velocity in the x-axis. If the total time of flight is 6 seconds, then at 3 seconds the reaches its maximum height. Also, there is no given initial velocity, which means any useful calculation is impossible.

Jerry bought a bottle of perfume for a gift for his wife.The perfume cost $92 before tax.

If the total price including tax was $98.90, find the tax rate.

Answers

First, you need to find how much money the tax was (98.90-92=6.9) Then, divide the tax by the price without the tax to find the tax rate (6.9/92=.075) then multiply the answer by 100 (.075*100=7.5)The tax rate is 7.5%

Renee is playing a game with marbles and a spinner. The spinner has four sections: orange, black, purple, and white. The marbles are kept in a bag and come in three colors: orange, black, and purple. Renee first spins the spinner and then picks a marble from the bag without looking. What is the probability that the color of the marble matches the color on which the spinner lands? brainly

Answers

Answer:

(1)/(16) Is the chance of the colours matching.

Step-by-step explanation:

The possibility of the spinner landing on an orange side is (1)/(4)

and the possibility of the marble being orange is (1)/(4) in this case you have to remember, in the fraction, you have 4 possibilities and 1 desirable outcome, when you have two dependant possibilities you have to multiply them:

(1)/(4) * (1)/(4)

And the result of that multipliction is (1)/(16) which is the probability of the marble and the spiner colours matching.

How many 1-cm-diameter ball bearings can be made using 5.24 cm3 of molten steel?

Answers

D = 1 --> r = 0.5
V=4/3•pi•r^3 = 4/3•3.14•(.5)^3 = 0.52
5.24 / 0.52 = 10.01
So you can make 10 ball bearings out of that amount of steel.

Answer:

C

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= 5x² - 3 - ( x² - 4x - 8) ← distribute parenthesis by - 1

= 5x² - 3 - x² + 4x + 8 ← collect like terms

= (5x² - x² ) + 4x + (- 3 + 8)

= 4x² + 4x + 5

Answer:

The answer is C. (f-g)(x) simplifies to 4x²+4x+5
