Answer:
checking account A is the better deal.
Step-by-step explanation:
A charges a monthly service fee = $12.00
Wire transfer fee = $10.50
B charges a monthly service fee = $21.00
Wire transfer fee = $8.50
If the requirement is four wire transfer per month
A charges for 4 wires = 10.50 × 4 = $42.00
and adding monthly service fees = 42.00 + 12.00 = $54.00
B charges for 4 wires = 8.50 × 4 = $34.00
and adding monthly service fees = 34.00 + 21.00 = $55.00
Therefore A charges less than B, so checking account A is the better deal.
Steps:
1. calculate the values of y at x=0,1,2. using y=5-x^2
2. calculate the areas of trapezoids (Bottom+Top)/2*height
3. add the areas.
1.
x=0, y=5-0^2=5
x=1, y=5-1^2=4
x=2, y=5-2^2=1
2.
Area of trapezoid 1 = (5+4)/2*1=4.5
Area of trapezoid 2 = (4+1)/2*1=2.5
Total area of both trapezoids = (4.5+2.5) = 7
Exact area by integration:
integral of (5-x^2)dx from 0 to 2
=[5x-x^3/3] from 0 to 2
=[5(2-0)-(2^3-0^3)/3]
=10-8/3
=22/3
=7 1/3, slight greater than the estimation by trapezoids.
Answer:
10 percent
Step-by-step explanation:
i took a test
tan x = opp/hyp
x is the side of the building and 6 is the distance from the bottom of the ladder to the building
tan 13 = 6/x
multiply both sides by x
x tan 13 =6
divide both sides by tan 13
x = 6/ tan 13
x = 26
The ladder goes 26 ft up the building
Answer:
1. .........................................
- 2x = 3
- x = 3/2 Fraction
- x = 1.5 Decimal
2. ..........................................
- 5y = 3
- y = 3/5 Fraction
- y = 0.6 Decimal
3. ..........................................
- 0.3z = 0.009
- z = 0.009/0.3 = 9/300 = 3/100 Fraction
- z = 0.09 Decimal
