Answer: f(x) = 64 * (3/4)^x
Step-by-step explanation: f(x)=ab^x
When x=0 f(x) = 64
64 = ab^0
b^0 =1 so
64 =a
f(x)=64 b^x
When x=1 f(x) = 48
48 = 64 *b
Divide by 64
48/64 =b
6/8 =b
3/4 =b
f(x) = 64 * (3/4)^x
Hey there!
To find the area, we multiply the length by the width! The carpet will cover the area of the room.
24×15=360
But, the carpeting is sold in square yards, not feet. There are three feet in a yard, which means that one yard is 1/3 feet. Since we have 360 square feet, we will divide it by three to get yards.
360/3=120
Therefore, the office would need 120 square yards of carpeting.
Have a wonderful day!
Answer:
c. $399.20
Step-by-step explanation:
multiply 499 by .20 and get 99.8 subtract this from 499 get 399.20
Answer:
Step 1 : Plug values into the quadratic formula
x = -(-5) +/- √ (-5)^2 - (4)(2)(-3) / (2)(2)
Step 2 : Solve
x = 5 +/- √ 25 + 24 / 4
x = 5 +/- √ 49 / 4
x = 5 +/- 7 / 4
x1 = 5 - 7 / 4 AND x2 = 5 + 7 /4
x1 = -1/2 OR - 0.5
x2 = 3
Hope this helps!!
