If the value of θ is 46.4°. Then the value of the cosine of θ will be 20/29.

<h3>What is trigonometry?</h3>

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The value of sine of θ is 21/29.

Then the value of θ will be

sin θ = 21/29

     θ = sin⁻¹(21 / 29)

     θ = 46.4°

Then the value of the cosine of θ will be

cos θ = cos 46.4°

cos θ = 20/29

Drinking and Driving Among High School Students The percentage of high school students who drink and drive stood at 17.5% at the
Vikki [24]

Answer:

Step-by-step explanation:

The percentage of high school students who drink and drive at the beginning of 2001   =   17.5%

The percentage of high school students who drink and drive at the beginning of 20011   =   10.3%

Rate of decrease = 17.5 - 10.3 / 10

= .72

The required linear function

f(t) =  - 0.72 x t + 17.5

b ) Rate of decrease in percentage = (17.5 - 10.3) / 10

= .72 %

c )  Percentage of high school students who drink and drive  at the beginning of 2014

t = 2014 - 2011 = 13

f(t) =  - 0.72 x t + 17.5

= - .72 x 13 + 17.5

= 8.14 %

How much money will be in the account at the end of 2 years if $134 is invested at 5.125% earning simple interest?
GREYUIT [131]

Answer:

$ 147.74

Step-by-step explanation:

P = $ 134

t = 2 years

r = 5.125% = 0.05125

Interest = P*r*t

            = 134 * 2 * 0.05125

           =  13.735

          = $ 13. 74

Total money = P + interest

                    = 134 + 13.74

                    = $ 147.74
