Answer:

Step-by-step explanation:

f(x)=x^2+5x g(x)=5‒x

f(3)=3^2+5(3) g(3)=5‒3

f(3)=9+15 g(3)=2

f(3)=24

f(3)+g(3)=24+2

=26

You have a wire that is 38 cm long. you wish to cut it into two pieces. one piece will be bent into the shape of a square. the o

erica [24]

Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2 $\pi$ r=x
r= $\frac{x}{2 \pi }$
Area= $\pi$ r^2
so..
A= $\pi$ ( $\frac{x}{2 \pi }$ )^2
= $\pi$ ( $\frac{x^{2} }{4 \pi ^{2} }$ )
= $\frac{x^{2} }{4 \pi }$

(38-x) is perimeter
then
$\frac{38-x}{4}$
( $\frac{38-x}{4}$ )^2
$\frac{x^{2} }{4 \pi }$ + ( $\frac{38-x}{4}$ )^2
then you graph it and it equals
16.716 cm the circumference of the circle

sammy [17]

There will be a 25 grams left after 3240 years.

The half-life of Radium-226 is 1620 years. If we divide 3240 by 1620 the answer is 2. So that means the amount of Radium-226 will divide in half twice.

100 / 2 = 50 / 2 = 25
