Can someone help me with number one? 1. Given right triangle ABC shown below, do the following:
(a) Measure the three side lengths to the nearest millimeter:
AB=
BC =
AC =
(b) Based on your measurements in (a) state the value of each of the
following in decimal form. Round to the nearest thousandth.
A
B
sin A=
cos A=
tan A=
sine
cosine
(c) Given the partial table of trigonometric
values shown below, which angle in the
table is closest to the mZA? Verify using
your protractor.

step-by-step explanation:

20-2= what

54.667> 54.666

17.889< 17.899

these are both true

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:
