Answer:

16 responses

Step-by-step explanation:

we know that

A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

a_n=r^{n-1}

where

a_n----> n^{th} term of the sequence

r ---> is the common ratio

a ---> the first term of the sequence

a=50\\r=100\%-10\%=90\%=90/100=0.90

substitute

a_n=50(0.90)^{n-1}

For n=12

substitute

a_n=50(0.90)^{12-1}=16

maksim [4K]

Answer:

8

Step-by-step explanation:

This can be solved using intersecting chord theorem. This tells us that when 2 chords intersect inside a circle, the 4 segment it creates, each individual segments' products are equal.

Thus, we can say that the product of 5 and x is equal to the product of 10 and 4. Thus:

5*x=10*4\\5x=40\\x=\frac{40}{5}\\x=8

Hence x = 8 is the correct answer

1. When a cannonball is fired, the equation of its pathway can be modeled by h = -1612 + 128t.
sashaice [31]

Answer:

The maximum height of the ball is 256m

Step-by-step explanation:

Given the equation of a pathway modelled as pathway can be modeled by h = -16t² + 128t

At maximum height, the velocity of the ball is zero.

velocity = dh/dt

velocity = -32t + 128

Since v = 0 at maximum height

0 = -32t+128

32t = 128

t = 128/32

t = 4seconds

The maximum height can be gotten by substituting t = 4 into the modelled equation.

h = -16t² + 128t

h = -16(4)²+128(4)

h = -16(16)+512

h = -256+512

h = 256m
