Answer:
Step-by-step explanation: First figure what’s in the parentheses. (3-2*2) wanna do 2*2 That’s 4 then (3-4) = -1. 2+(-1)*1. Then multiply -1 by 1 which is -1. Then 2+(-1)= 1
You can solve this using fractions, and say that 32/850 are defective. To find the amount of defective widgets out of 22,000, we can then multiply to make the denominator 22,000. To work out what we need to multiply by, we can just do 22,000 ÷ 850 = 25.88. Now if we multiply 32 by 25.88, we get our answer as 828 widgets.
I hope this helps!
Answer: exponential decay (choice B)
The variable x in the exponent tells us that this is an exponential function. The fact that the base 1/2 = 0.5 is between 0 and 1 indicates that the value of y will decay or get smaller as x increases. Visually, it graphs out a curve that goes downhill as you read from left to right.
side note: The function f(x) = 7*(1/2)^x can be written as y = 7*(0.5)^x. It has a horizontal asymptote of y = 0 meaning that the curve will get closer and closer to the x axis, but never actually touch it.
The <em><u>correct answer</u></em> is:
D) The amount a person pays for gas compared with the number of gallons purchased
Explanation:
A constant rate of change means that for every x, y increases the same amount.
In the situation "The amount a person pays for gas compared with the number of gallons purchased
," the independent quantity, or x-value, is the number of gallons, and the dependent quantity, or y-value, is the amount paid. Since gas has a set price per gallon, for every gallon purchased, the total amount paid goes up the same amount. This means it has a constant rate of change.
