Question
What does 3P2 equal?
Solution 1

No one has mentioned, so IÂ
will. What youÂ areÂ looking forÂ isÂ the permutation of 3 things taken 2 at a time. In other words, how many different unique waysÂ areÂ there to arrange 3 items, say colored balls, taking 2 of them for each group. By unique, I mean that 1 red and 1 blueÂ is the sameÂ as 1 blue and 1 red,

Solve this quadratic equation for cos x.
Since a + b + c = 0, use shortcut.
One real root is cos x = 1 and the other is cosx=ca=âˆ’12.
Trig table and unit circle -->
a. cos x = 1 --> arc x = 0, and arc x=2Ï€
b. cosx=âˆ’12 --> arc x=Â±2Ï€3
The arc âˆ’2Ï€3 is co-terminal to the arc: 4Ï€3

Question
How many times do 12 go into 30
Solution 1
2 times with 6 left over because you would see how many times without going over and that would be 2 because 2x12 equals 24 amd 3x12 equals 36 bit that is ocer thirty then 30-24 equals 6. 6 is your remainder. Your full answer is 2 r4
Question
determine the amount of an investment if $400 is invested at an annual interest rate of 7.25% for 7 years. round to the nearest penny. Solution 1 Equation for one year: 0.0725(400) But we have 7 years: 7(0.0725(400)) Multiply in the parentheses 7(29) = 203 400 + 203 = 603 You now have$603, and made $203 Question The equation for a projectile's height versus time is h(t)=-16t^2+Vt+h. A tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an initial speed of 130 feet per second. Which equation correctly models the ball's height as a function of time? Solution 1 The maximum height at the moment is 266.0625 ft. Projectile's height The equation for a projectile's height versus time is h = 2 V = 130 Substitute these values into the function Take the first derivative Equate the derivative with zero . Solve the equation -32 t + 130=0 32 t = -130 t = -130 /(-32) = 4.0625(s) . Find the maximum height at the moment t = 4.0625 (s) h(4.0625) = - 264.0625+528.125+2 = 266.0625 ft. Therefore, the maximum height at the moment is 266.0625 ft. To learn more about projectile's height brainly.com/question/27750474 #SPJ2 Solution 2 For this case we must use the projectile equation for this problem. Â We have then: Â h (t) = - 16t ^ 2 + Vt + h Â Where, Â V: initial speed Â h: height Â For the tennis ball we have: Â h (t) = - 16t ^ 2 + 130t + 2 Â Answer: Â An equation that correctly models the ball's height as a function of time is: Â h (t) = - 16t ^ 2 + 130t + 2 Question Juan Ramirez sells suits in a major department store on weekends. He earns a commission of 5% on the first 10 suits he sells. If he sells more than 10, he earns another 3% on the additional suits. Last weekend Juan sold 13 suits priced at$250 each. What was his commission? A. $185.00 B.$260.00 C. $147.50 D.$210.40
Solution 1
C. $147.50 the first 10 suits would sell at 250 each totaling 2500 which means he earns 5% of$2500, which is 0.05 x 2500 = $125.Â The next 3 suits which also sold at 250 which totals$750, he makes 3% of that amount which is 0.03 x 750 = $22.50. Together is makes 125 + 22.50 =$147.50 in commission.

Question
The stack on the left is made up of 15 pennies, and the stack on the right is also made up of 15 pennies. If the volume of the stack of pennies on the left is 390 mm3, what is the volume of the stack of pennies on the right in cubic millimeters?
Solution 1

Answer: Â The required volume is 390 mmÂ³.

Step-by-step explanation: Given that the stack on the left is made up of 15 pennies, and the stack on the right is also made up of 15 pennies. The volume of the stack of pennies on the left is 390 mmÂ³.

we are to find the volume of the stack of pennies on the right in cubic millimeters.

The number of pennies on the left and right are same, equal to 15.

Also, the volume of the stack of pennies on the left is 390 mmÂ³.

Since the number of pennies on the right and left are equal, so the volume of the stack on the right and left are also equal.

Therefore, the volume of the stack of pennies on the right is 390 mmÂ³.

Thus, the required volume is 390 mmÂ³.
