Type the correct answer in the box. oliver plans to purchase a $1,500 certificate of deposit (cd) at his bank. the cd will earn 2.3% interest, compounded semi-annually. write an exponential expression in the form a(b)c, where b is a single value, to find the value of the cd, in dollars, after t years. round any decimals to the nearest ten-thousandth. do not include dollar signs or percent symbols in the expression.

the exponential expression to find the value of the cd, in dollars, after t years will be:  

step-by-step explanation:

formula of compound interest:   , where final value after years,   initial value, rate of interest in decimal and number of compounding in a year.

oliver plans to purchase a $1,500 certificate of deposit (cd) at his bank. that means,  

the cd will earn 2.3% interest, compounded semi-annually.

so,   and  

now, plugging these values into the above formula, we will

(rounded to the nearest ten-thousandth)

so, the exponential expression to find the value of the cd, in dollars, after t years will be:  

250

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
