Answer:
1/4
Step-by-step explanation:
using the product-to sum formulas, this is
1/2 (cos(75+15) + cos(75-15))
The formula for the volume of a right circular cone is V =

. In solving for the volume of the first french fries cones V =

= 75.398

. In solving for the height of the second french fries cones with a new radius of 4, the formula is rearranged to h =

=

= 1.5 in or inches. The height of the new cones will be 1.5 inches.
It's B :3 make brainiest please :(

Answer:
<h2>
<u> 3.2%</u></h2>
Step-by-step explanation:
Step one:
given data
principal P= $1800
time t= 1 year
Final amount A=1857.60
rate r=?
Step two:
we are expected to solve for the rate, let assume the investment is a simple interest type.
A=P(1+rt)
solve for r we can substitute our data
1857.60=1800(1+r*1)
1857.60=1800+1800r
1857.60-1800=1800r
57.6=1800r
r=57.6/1800
r=0.032
0.032*100= 3.2%
<u>This shows that the rate is 3.2%</u>
