The Pythagorean Identity states that:
(sin x)2 + (cos x)2 = 1
Given sin 0 = 2/5, find cos 0.
cos O = ✓21/ [ ? ]
Simplify the fraction.
Answer:
cos (theta) = √21/5
Step-by-step explanation:
sin (theta) = 2/5
(sin (theta))^2 = 4/25
4/25 + (cos (theta))^2 = 1
(cos (theta))^2 = 1 - 4/25 = 21/25
cos (theta) = √21/5

ABCD is a parallelogram. Find the value of the ratio in simple form.
m
Answer:
The ratio is 1:1
Step-by-step explanation:
angle B and angle D are equal because these are the opposite angles of a parallelogram
Angle B = 180 degree - 30 degree
= 150 degrees
Angle D = 180 degree - 30 degree
=150 degrees
Ratio 120 :120

The function sin) = 2n - 5 represents the value of the nth term in a sequence. What is the sum of the 1st and 6th terms of the sequence?
Answer:
4
Step-by-step explanation:
Using the nth term formula
a₁ = 2(1) - 5 = 2 - 5 = - 3
a₆ = 2(6) - 5 = 12 - 5 = 7
Then
a₁ + a₆ = - 3 + 7 = 4

What is the vertex of the graph of the quadratic function f(x) = x2 + 6x +10?
F (3,-1)
G(-3,-1)
H(-3,1)
J(3,1)
Answer:
(-3, 1) (Answer H)
Step-by-step explanation:
f(x) = x^2 + 6x +10 can be rewritten by "completing the square" as
f(x) = (x + 3)^2 + 1, and by comparing this to y = (x - h)^2 + k, we see that h is -3, k is 1, so the vertex, (h, k), is at (-3, 1) (Answer H)

Find the Area of the figure below, composed of an isosceles trapezoid and one
semicircle. Rounded to the nearest tenths place
10
Answer:
Area of given figure = 48.28 unit² (Approx.)
Step-by-step explanation:
Given:
Length of parallel lines are 10 , 4 respectively
Diameter of semi-circle = 4
Height of parallelogram = 6
Find:
Area of given figure
Computation:
Radius of semi-circle = Diameter of semi-circle / 2
Radius of semi-circle = 4 / 2
Radius of semi-circle = 2
Area of given figure = [1/2][Sum of parallel line][Height] + [πr² / 2]
Area of given figure = [1/2][10 + 4][6] + [(3.14)(2)² / 2]
Area of given figure = [1/2][14][6] + [(3.14)(4)/ 2]
Area of given figure = 42 + 6.28
Area of given figure = 48.28 unit² (Approx.)
