Vertical reflection over the x-axis, shrink of 1/3, right 3, up 2
Answer:
89.8 feet
Step-by-step explanation:
In ΔBCD, the measure of ∠D=90°, the measure of ∠B=75°, and DB = 93 feet. Find the length of BC to the nearest tenth of a foot.
We would solve the above question using Sine rule
The formula is given as:
DB/sin D = BC/sin B
93/sin 90 = BC/sin 75
We cross multiply
sin 90 × BC = 93 × sin 75
BC = 93 × sin 75/sin 90
BC = 89.83 feet
Approximately BC = 89.8 feet
To solve this, write an equation.
300 is your starting balance, add this to your equation.
300
You get 7% more each year, but you can't multiply by 7% because that will make it decrease by 93%. You have at add 1 to 7%.
300(1.07)
Lastly, the 18 variable for the years.
300(1.07)^18
Solve the equation and get $1013.97968 or $1013.98
