Answer:
v=ha^2/3
Step-by-step explanation:
Answer:
See pictures attached
Step-by-step explanation:
The conjunction is given by the intersection of 2 inequalities
-5 < x (or x > -5)
that is the set of real number such that x greater than -5, graphically is represented by picture 1 attached (the parentheses means that -5 IS NOT included)
and the inequality
x ≤ 7
which is the set of real number such that x less than or equal to 7, represented in picture 2 attached (the bracket means that 7 IS included)
When we intersect the two sets we obtain
– 5 < x ≤ 7
that is the set of numbers x such that x is greater than -5 AND x less than or equals to 7, which graphically is represented in picture 3 attached.
Using Quadratic formula,
x = 0.386, -3.886
Answer:
D.) 11.8 cm
Step-by-step explanation:
The short side has length ...
5·sin(30°) = 2.5
The long side has length ...
5·cos(30°) ≈ 4.33
The sum of all side lengths is ...
5 + 2.5 + 4.33 = 11.83 . . . . cm
The perimeter is about 11.8 cm.

The mnemonic SOH CAH TOA can help you remember the relationship between trig functions and side lengths:
Sin = Opposite/Hypotenuse ⇒ Opposite = Hypotenuse × Sin
Cos = Adjacent/Hypotenuse ⇒ Adjacent = Hypotenuse × Cos
