Answer:
Step-by-step explanation:
The amplitude is 6, so A=6.
Also, the midline is y=-3, so C=-3.
The period is 10, so 2pi/k = 10 -> k=5.
Now we need to determine if this is a sine graph or a cosine graph. As the y-intercept is not the value of C, we can determine that this is a cosine graph, and thus y=6cos(5x)-3.
3. (7+2)
A. 3. (2+7)=3.2+3.7=6+21=27
Answer:
y1 = -3, y2 = 3
Step-by-step explanation:
(2/3)y^2 + 14 = 20
(2/3)y^2 = 20 - 14
(2/3)y^2 = 6
y^2 = 9
y = -3 and y = 3
Answer:
Photo 1: (a) C
(b) A
(c) D
Photo 2: 12.0416cm
Photo 3: 15.5242cm
Step-by-step explanation:
Photo 1: (a) 6×4=24
(b) 6(5)+6=36
(c) 6×6=36
Photo 2: Using Pythagoras' Theorem,
Unknown side length= square root symbol [(8×8)+(9×9)]
= 12.0416cm (6sf)
Photo 3: Using Pythagoras' Theorem,
AC= square root symbol (AB^2+BC^2)
=square root symbol [(15×15)+(4×4)]
= 15.5242cm (6sf)
