PLEASE HURRY!!! AB = 20 cm, m∠A = 30° , and $m∠C = 45° . Express the number of centimeters in the length of BC in simplest radic

MrRissso [65]

Using the Sine Rule:-

20 /sin 45 = BC / sin 30

BC = 20 sin 30 / sin45

= 20 * 1/2 / 1 / sqrt2
= 20 * 1/2 * sqrt2
= 10 sqrt2 answer

Answer:

11,880π in^3

Step-by-step explanation:

The volume of a cylinder = π r^2 h

Large Cylinder V = π * 15^2*40 = 9,000π in^3

Small Cylinder V = π * 12^2 * (60-40) = 2880π in^3

Adding: the total volume of the model = 11,880π in^3

A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find

Wewaii [24]

Answer:

$y=120,000(1.055)^x$

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$y=a(1+r)^x$

where

y is the value of the home

x is the number of years

a is the initial value

r is the rate of change

we have

$a=\$120,000\\r=5.5\%=5.5/100=0.055$

substitute

$y=120,000(1+0.055)^x$

$y=120,000(1.055)^x$
