<span>The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500. After 2 years, the item is worth $551.25. Which equation represents y, the value of the item after x years? idk sorry</span>
This circle has a sector area of 17pi/2 and a central angle of 17pi/90.
So, the whole angle of the circle would be 2pi. To find the area of a sector, you can use the formula A=R*Angle
17pi/2= R* 17pi/90
R=45
A=45^2 * pi
A=90 pi or 282.6
Answer:
10 units
Step-by-step explanation:
Hansen walks two units down to the dry cleaners, and walks 8 units to the right to the radio tower. If you add the units together you get 10.
Answer:
The time required them working together to shovel the snow is T = 1.428 hours
Step-by-step explanation:
Given data
Time taken by first person to shovel the snow
= 2 hours
Time taken by second person to shovel the snow
= 5 hours
Time taken by both persons to shovel the snow

Put all the values in above equation we get

T = 1.428 hours
Therefore the time required them working together to shovel the snow is T = 1.428 hours
Answer:
x = +2, x = -2
Step-by-step explanation:
The equation to solve in this problem is

The first step we do is to subtract 35 on both sides of the equation, so we get:

Now we simplify the equation by dividing both terms by 10:

Now we observe that the term on the left is the difference between two squares, so it can be rewritten using the property:

Where here,
a = x
b = 2
So we can rewrite the equation as:

And this equation is zero when either one of the two factors is zero, so the two solutions are:
