Answer: Choice C</h3>
Started in Quadrant II and ended in Quadrant IV.
==========================================================
Explanation:
Refer to the diagram below. It shows how the four quadrants are labeled using roman numerals. We start in the upper right corner (aka northeast corner) and work counterclockwise when labeling quadrant I, II, III, and IV in that order.
The green point A is located in quadrant II in the northwest. Meanwhile point B in red is in the southeast quadrant IV.
Therefore, we started in <u>quadrant II</u> and ended in <u>quadrant IV</u> which points us to <u>choice C.</u>
Answer: cos (25° + 10°)
Step-by-step explanation: The expression:
sin(25°) cos(10°) − cos(25°) sin(10°)
is associated to the expression for the cosine of the sum of two angles that is:
cos (α+β) = sinα *cosβ -cosα*sinβ
Hence if we do α = 25° and β = 10°
by subtitution we get:
cos (25° + 10°) = sin(25°) cos(10°) − cos(25°) sin(10°)
Answer:
Step-by-step explanation:
Tanisha, Elicia, and Ajua are cousins. Tanisha is twice as old as Ajua, and Elicia is two years older than Tanisha. The sum of all their ages is 37. Use variable expressions and calculate the age of each girl
Let us represent:
The age of :
Tanisha = a
Elicia = b
Ajua = c
Tanisha, Elicia, and Ajua are cousins. Tanisha is twice as old as Ajua
a = 2c
c = 2/a
Elicia is two years older than Tanisha.l
b = a + 2
The sum of all their ages is 37.
a + b + c = 37
We substitute
a + a + 2 + 2/a = 37
2a + 2 + 2/a = 37
Use variable expressions and calculate the age of each girl
Answer:
Distribute 1/2 to all of the terms inside the parenthesis and you will get: 3e - 3/2f - 3/8
