I’m also doing my homework but just search how to solve for an area of a circle :) I’m 100% sure it will help
<h3>4cos ^4(x) -5cos^2(x)+1=0</h3><h3>(u^-1) (4u^-1)=0</h3><h3>(u^-1)=0</h3><h3>u^=1</h3><h3>u=√1</h3><h3>u=1</h3><h3>u=±1</h3><h3>cos (x)=±1</h3><h3>x=0 or π</h3><h3 /><h3>4u^-1=0</h3><h3>4u^=1</h3><h3>u^=1/4</h3><h3>u=√1/4</h3><h3>u=1/2</h3><h3>u= ±1/2</h3><h3>cos (x)=±1/2</h3><h3>x= π/3 or 4π/3</h3><h3 /><h3>x= 0, π/3, π, 4π/3</h3>
Answer:
The two equations are
r = 600m
and
r/600 = m
Step-by-step explanation:
Here, we want to write equations
The equation is;
r(m) = 600m
where r is the amount spent and m is the number of months
r = 600m
and r/600 = m
Answer:
Jenn's account has a greater simple interest rate.
Lindsey's interest in 1 year was $3
Jenn's interest in 2 years was $7.50 if you divide $7.50 by 2 the answer would be 3.75 therefore Jenn's account has the greater simple interest rate.
