Answer:
The answer to your question is:
a) sin Ф = -3/√10
b) cos Ф = 1/√10
c) tan Ф = -3
Step-by-step explanation:
See the picture below
just remember
sin Ф = opposite / hypotenuse
cos Ф = adjacent / hypotenuse
tan Ф = opposite / hypotenuse
Answer:
6cm
Step-by-step explanation:
Volume of cuboid = length × breadth × height
Length = x
Breadth = 4cm
Height = 5cm
Volume = 120cm³
Volume = 4 × 5 × x
120 = 20x
Divide both sides by 20
20x/20 = 120/20
x = 6cm

Answer:
y > 11/2
Step-by-step explanation:
This is solved the same way a 3-step equation is solved.
<u>Step 1</u>: subtract the smaller variable term from both sides.
4y -2y +3 > 2y -2y +14
2y +3 > 14
<u>Step 2</u>: subtract the constant with the variable term.
2y +3 -3 > 14 -3
2y > 11
<u>Step 3</u>: divide by the coefficient of the variable.
2y/2 > 11/2
y > 11/2

<em>Additional comment</em>
By choosing to subtract the smaller variable term in the first step (regardless of which side of the inequality it is on), we ensure that the remaining variable coefficient is positive. That means we can do step 3 without worrying about changing the direction of the inequality symbol, because we're dividing by a positive number.
