Perry invested in property that cost him $1500. Five years later it was worth $3000, and $10 years from his original purchase, i

myrzilka [38]

Answer:

Step-by-step explanation:

A linear function increases/decreases by a certain amount every year. As it changes 1500 over the first 5 years (300 per year) and 3000 over the next 5 (600 per year), this cannot be liner

A quadratic function goes down then up, or vice versa. This consistently goes up, and is therefore not quadratic

A trigonometric function also goes up and down, so it is not trigonometric

Therefore, as an exponential function can keep going up at different rates over time, this is an exponential function

Decrease $7500 by 7%<br>please help i need step by step explanation

soldier1979 [14.2K]

(100% - 7%) × 7,500

= 93% × 7,500

= 93 ÷ 100 × 7,500

= 93 × 7,500 ÷ 100

= 697,500 ÷ 100

= 6975
hope this helped

There are 1,800 pastries in a bakery shop. 45% of them are pretzels and the rest are croissants. How many croissants are there?

blondinia [14]

Answer: There are 990 croissants

Step-by-step explanation:

If 45% of them are pretzels then 55% of the pastries hs to be croissants.

Multiply 55% by the total number of pastries to find the number of croissants.

55% * 1,800 = 990

"We might think that a ball that is dropped from a height of 15 feet and rebounds to a height 7/8 of its previous height at each

tatyana61 [14]

Answer:

Total Time = 4.51 s

Step-by-step explanation:

Solution:

- It firstly asks you to prove that that statement is true. To prove it, we will need a little bit of kinematics:

y = v_o*t + 0.5*a*t^2

Where, v_o : Initial velocity = 0 ... dropped

a: Acceleration due to gravity = 32 ft / s^2

y = h ( Initial height )

h = 0 + 0.5*32*t^2

t^2 = 2*h / 32

t = 0.25*√h ...... Proven

- We know that ball rebounds back to 7/8 of its previous height h. So we will calculate times for each bounce:

$1st : 0.25*\sqrt{15}\\\\2nd: 0.25*\sqrt{15} + 0.25*\sqrt{15*\frac{7}{8} } + 0.25*\sqrt{15*\frac{7}{8} } = 0.25*\sqrt{15} + 0.5*\sqrt{15*\frac{7}{8} }\\\\3rd: 0.25*\sqrt{15} + 0.5*\sqrt{15*\frac{7}{8} } + 2*0.25*\sqrt{15*(\frac{7}{8} })^2\\\\= 0.25*\sqrt{15} + 0.5*\sqrt{15*\frac{7}{8} } + 0.5*\sqrt{15*(\frac{7}{8} })^2\\\\4th: 0.25*\sqrt{15} + 0.5*\sqrt{15*\frac{7}{8} } + 0.5*\sqrt{15*(\frac{7}{8} })^2 + 2*0.25*\sqrt{15*(\frac{7}{8} })^3 \\\\$

$= 0.25*\sqrt{15} + 0.5*\sqrt{15*\frac{7}{8} } + 0.5*\sqrt{15*(\frac{7}{8} })^2 + 0.5*\sqrt{15*(\frac{7}{8} })^3$

- How long it has been bouncing at nth bounce, we will look at the pattern between 1st, 2nd and 3rd and 4th bounce times calculated above. We see it follows a geometric series with formula:

Total Time ( nth bounce ) = Sum to nth ( $\frac{1}{2}*\sqrt{15*(\frac{7}{8})^(^i^-^1^) } - \frac{1}{4}*\sqrt{15}$ )

- The formula for sum to infinity for geometric progression is:

S∞ = a / 1 - r

Where, a = 15 , r = ( 7 / 8 )

S∞ = 15 / 1 - (7/8) = 15 / (1/8)

S∞ = 120

- Then we have:

Total Time = 0.5*√S∞ - 0.25*√15

Total Time = 0.5*√120 - 0.25*√15

Total Time = 4.51 s
