Answer:

Increased by a factor of 4

Step-by-step explanation:

The original circumference is:

C1 = 2 * pi * r1

The new circumference is:

C2 = (2 * pi * r2)

"circumference that is 4 times larger than the original"

(2 * pi * r2) = 4 (2 * pi * r1)

Rewriting:

r2 = 4r1

Answer:

The radius of the original circle is:

increased by a factor of 4

Hope this helps :)

Answer:

Below.

= 99.7%

= 100 - 99.7%/2

= 0.3/2

= 0.15%

100% - 0.15%

= 99.85%

If a cannonball is shot directly upward with a velocity of 160 ft per second, its height above the ground after t seconds is gi

Contact [7]

Step-by-step explanation:

If a cannonball is shot directly upward with a velocity of 160 ft per second. Its height as a function of time is given by :

$h(t)=160t-16t^2$ .......(1)

t is in seconds

(a) Velocity is given by :

$v=\dfrac{dh}{dt}\\\\v=\dfrac{d(160t-16t^2)}{dt}\\\\v=(160-32t)\ ft/s$

Acceleration is given by :

$a=\dfrac{dv}{dt}\\\\a=\dfrac{d(160-32t)}{dt}\\\\a=-32\ ft/s^2$

(b) For maximum height put $\dfrac{dh}{dt}=0$

i.e.

$160-32t=0\\\\t=5\ s$

Put t = 5 s in equation (1). So,

$h(5)=160t-16t^2\\\\h(5)=160(5)-16(5)^2\\\\h(5)=400\ ft$

h(t) = 0

$160t-16t^2=0\\\\t(160-16t)=0\\\\t=0,t=10\ s$

Hence, this is the required solution.

Q # 4 please help to solve

The second choice - 3.1%

All you have to do is multiply the probability by itself five times to get the total probability for the next five days.

1/2*1/2*1/2*1/2*1/2
= 1/2!
= 1/32
= 0.0313
= 3.13%

3.13 rounded off to the nearest tenth is 3.1%
There is 3.1% probability that Shania will arrive at school on time for the next five days.
