Step-by-step explanation:
Area of rectangle(A)=l×b
=4x×(x^2-2x+6)
= 4x^3-8x^2+24x
Let's first start off by making 2/10 the same denominator as 5/100. To do this you would need to multiply both sides of the fraction by 10. You wild end up with 20/100. Now we worry about the striped fish. There are 5/100 striped fish, since we have the same denominator we can add them together!
20+5=25
25/100 is reduced to 1/4!
Answer:
Step-by-step explanation:
If the radius of the circle is equal to
and the area is given as 45, then
which simplifies to
and to the nearest tenth,
r = 3.9
So for this, we will be using the exponential equation formula, which is y=ab^x, with a = initial value and b = growth/decay. Since the value is increasing, you would add 1 and 0.02(2% in decimal form) together to get 1.02, which will be the b variable. And since we are starting in 2005 with $8 and trying to figure out the value in 2011, 8 will be the a variable and 6 will be the x variable (2011-2005=6)
With this info, our equation will be: y = 8(1.02)^6
Firstly, solve 1.02^6: y = 8(1.12616242)
Next, multiply and your answer will be (rounded to the hundreths): y = $9.01
