Answer: B
Step-by-step explanation:
It cant be A or C since the intersection does not touch the y axis and it isn't D since it is closer to -4 than -4 1/2
Answer:
15 units²
Explanation:
Well true that the calculations, it is true that the equation through solving a parallelogram is the same as the equation of a rectangle area.
Answer:$99.25
Step-by-step explanation:
Each by a sweatshirt including Amanda 3x25.50=$76.50 ,2 of them by popcorn so 2x4.75=$9.50, Amanda buys a hotdog 1x3.50=3.50, One friend bought nachos so 1x3.00=$3.00 and then Each girl bought a drink so 3x2.25=$6.75.
You have to add up all the totals which is 76.50+9.50+3.50+3.00+6.75 once you add those you get $99.25 that’s the total amount spent at the game.
Question
a) What is the decay factor?
b) What is the percent decrease?
c) Estimate the number of black and white TV's sold in 1999.
Answer:
a. Decay factor = 0.85
b. Percent decrease = 15%
c. 19.363 million TVs were sold
Step-by-step explanation:
Given
Solving (a): The decay factor
An exponential function has the form
Where b is:
By comparison:
Solving (b): Percentage decrease:
Percentage decrease P is calculated as follows:
Substitute 0.85 for b
Convert to percentage
Solving (c): TVs sold in 1999
First, we need to determine the value of t for 1999
In 1997, t= 0
In 1998, t= 1
In 1999, t= 2
So, we substitute 2 for t in:
Answer:
The x-intercept is 5 and the y-intercept is 20. To find the x-intercept plug in y = 0 into the equation and then solve for y and to find the y-intercept plug in x = 0 into the equation and solve for y.
