Answer:
In words, Cosine theta equals plus or minus square root of seven over 4,tangent theta equals plus or minus three over root seven
Step-by-step explanation:
Given that sin ∅ =3/4 It means the ratio of the opposite side to the hypotenuse side is 3:4.
Using the Pythagoras theorem we can calculate the hypotenuse adjacent as follows.
a²+b²=c²
a²=c²-b²
a²=4²-3²
a²=16-9
a²=7
a=√7
Then Cos ∅= opposite/ adjacent
=√7/4
Then Tan ∅ = opposite/adjacent
=3/√7
In words, Cosine theta equals plus or minus square root of seven over 4,tangent theta equals plus or minus three over root seven.
Answer:
checking account A is the better deal.
Step-by-step explanation:
A charges a monthly service fee = $12.00
Wire transfer fee = $10.50
B charges a monthly service fee = $21.00
Wire transfer fee = $8.50
If the requirement is four wire transfer per month
A charges for 4 wires = 10.50 × 4 = $42.00
and adding monthly service fees = 42.00 + 12.00 = $54.00
B charges for 4 wires = 8.50 × 4 = $34.00
and adding monthly service fees = 34.00 + 21.00 = $55.00
Therefore A charges less than B, so checking account A is the better deal.
Answer:
c) bajo: $1.62; mediano: $1.80; grande: $2.03
Step-by-step explanation:
Insert numbers from the table into a linear equation (ignore time column) and use Cramer's Rule.
55x+53y+54z=299.12
17x+22y+25z=117.89
30x+23y+29z=148.97
x, bajo = 1.62
y, mediano = 1.8
z, grande = 2.03
Answer:
Police officers, whether plain-clothed or uniformed, carry a variety of equipment with them on service calls. Police in uniform carry much more equipment than those in plain clothes, and members of special operations teams, such as SWAT and crowd-control units, carry even more, sometimes including full body armour complete with helmet, leg pads, and shield.
