Solve by finding the angle of B. Round to the nearest tenth of a degree.

22.3 degrees

Step-by-step explanation:

bisector from C to c at a 90 degrees is 2.658427

my using 6 * sin(26.3)

switch sides and use inverse sin to get 22.3 degrees

20

Step-by-step explanation:

Law of sines. 7/sin26.3 x 6/sinb

7sinb=sin26.3x6

7sinb=sin26.3x6 (/7)

sinb=0.44307x6/7

sinb=2.6584/7

sinb=0.37977 (/sin-1)

b=22.3 and closest to 20

I hope it's correct

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
