Answer:
Vertical shift is 2 units top and horizontal shift is 
units to the right
Step-by-step explanation:
Consider the function f(x) = a cos(bx + c) + d.
In this graph, the horizontal shift is -c/b and the vertical shift is d.
Let's compare our graph, f(x) = -3 cos(2x - π) + 2 with this graph.
Here, a = -3, b = 2, c = -π and d = 2.
So, vertical shift = d = 2 units top and
horizontal shift = 
units to the right.
answer
width = 98 cm
length = 105 cm
set up equations
the perimeter of a rectangle = 2W + 2L
p = 2W + 2L
the perimeter is also 406
406 = 2W + 2L
we know that the length of the rectangle is 7 cm longer than the width so
L = W + 7
substitute equations and solve for width
plug L into p = 2W + 2L to get
406 = 2W + 2(W + 7) distribute the 2 to the terms in the parentheses
406 = 2W + 2W + 14
406 = 4W + 14
392 = 4W
W = 98
substitute equations and solve for length
now that we know the width, we can substitute W in L = W + 7 to find length
L = W + 7
L = 98 + 7
L = 105
final dimensions
width = 98 cm
length = 105 cm
Answer:
false
Step-by-step explanation:
(8/4)/2 = 1
8/(4/2) = 4
option c) The line segment AC is the diameter of circle F.
<u>Step-by-step explanation</u>:
- The 'diameter' is the line segment that passes through the center of the circle.
- In the circle shown, F is the center of the circle.
- The line segments EB and AC passes through the center point F.
- Therefore, both EB and AC are the diameters of the given circle.
- From the options given, option c) AC is the correct answer.
