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?
y = 500(0.05)x
y = 500(1.05)x
y = 500(0.1025)x
y = 500(1.1025)x

Y = 500(1 + r)^x; where r is the rate and x is the number of years.
500(1 + r)^2 = 551.25
(1 + r)^2 = 551.25/500 = 1.1025
1 + r = sqrt(1.1025) = 1.05

Therefore, the equation that represents y, the value of the item after x years is
y = 500(1.05)^x

Answer:

286

Step-by-step explanation:

Use term formula for +/-

Tn = a + (n-1)d

n= number of term

a= first number in sequence

d= difference between each number

T55 = 16 + (55-1)5

T55 = 16 + 270

=286

Kelly needs to order lunch for the 6 people at a business meeting. Her menu choices are chicken salad for acost of $5 per person
Lady bird [3.3K]
Hello There!! (: 
I'm Here to help!
If we say Kelly orders 1 chicken salad, then it means she ordered 5 egg salads. If she ordered x chicken salads, then she'll have to order the rest, which is <span>(6−x)</span> egg salads. For first equation, let's set y to be the meal's price. It consist of the price of all chicken salads ordered and the price of all egg salads ordered: <span>y=5x+4(6−x)</span> Again, x represents number of chicken salads ordered, and y represents the meal's price. A second equation would come to limit the price to the money Kelly has: <span>y≤28
</span> Notice there are more constraints to add on the values (x cannot be negative, no such thing negative number of salads or fractional number of salads) so just keep that in mind. Now, since we know the price based on the number of chicken salads, we can say for what number of salads it matches the second restriction: <span><span><span>5x+4(6−x)≤28</span><span>5x+24−4x≤28</span><span>x≤28−24</span><span>x≤4

Does this help you?
I Sure hope so have a goodnight ! (:

It would be 5sqrt2

a^2 + b^2 = c^2
5^2 + 5^2 = c^2
25 + 25 = c^2
50 = c^2
c = sqrt 50
c = 5sqrt2

I NEED HELP WITH NUMBER 4​
weeeeeb [17]

Answer:

4.5 inches

Step-by-step explanation:

To find the height in inches of the model, you need to change the ration into a fraction:

\frac{1}{50}

Then try to figure out the value of the denominator in terms of the ratio:

\frac{1}{50} =\frac{x}{725}

In this equation we need to figure out how much the denominator of the fraction is changing by, by dividing 725 by 50. Then, multiply that by one:

4.5
