Answer:
-3.872983346
Step-by-step explanation:
In this case we have: cos θ = 1/4 Whose possible solutions are: θ = 2 * pi * n - Acos (1/4) θ = 2 * pi * n + Acos (1/4) Where, n belongs to the natural numbers. As sin θ <0 then the solution is: θ = 2 * pi * n - Acos (1/4) For n = 1 we get: θ = 4.965069236 radians Thus: tan θ = tan (4.965069236) = - 3.872983346 Answer: tan θ = -3.872983346
THE ANSWER IS (1,1)
GOOD LUCK
Answer:
Try 20.
Step-by-step explanation:
To round 19.5 to the nearest whole number consider the tenths’ value of 19.5, which is 5 and equal or more than 5. Therefore, we have to round up: the whole number part of 19.5, 19, increases by 1 to 20, and the decimal point and all digits (.5) are removed.
19.5 rounded to the nearest whole number = 20
She has to pay $503.125 monthly till 4 years
<u>Step-by-step explanation:</u>
Cost of the ring = $30000
Add on = 5.5% of the cost of the ring
=( 5.5 x 30000) /100
= $1650
Down payment = 25% of the cost
= (25 x 30000) /100
= $7500
Time = 4 years
Loan amount = 30000 - 7500
=$ 22500
Total amount to pay = 22500 + 1650
= $24150
Monthly instalment= 24150/(4 x 12)
= $503.125
She has to pay $503.125 per month till 4 years.
