Answer:
a. $3.36
b. $70.86
Step-by-step explanation:
5% of $67.50 is $3.36
$67.50 + $3.36 = $70.86
Perimeter = 2(length + width)
16.8 = 2(3.6 + width)
3.6 + width = 16.8/2 = 8.4
width = 8.4 - 3.6 = 4.8 in
Answer: 55 to 90 for math; 50 to 90 for language arts
Step-by-step explanation:
Answer: The measure of the major arc is 68 degrees plus the measure of the small arc.
In the problem given, we don't know all the needed measurements (is there a diagram?). Therefore, we can find an expression for the answer, not the value itself.
The angles are related with the following expression.
Outside Angle = 0.5(Major Arc - Minor Arc)
Solving for the major arc gives us.
34 = 0.5(y - x)
68 = y - x
68 + x = y
Answer:
f(x) = 2(1/3)^x
Step-by-step explanation:
To find the parameters of this exponential equation, follow the instructions given in the hint.
__
b = 6/18 = 1/3 . . . . . divide 6 by 18 to find 'b'
18 = a(1/3)^-2 . . . . . substitute a point and 'b' in the equation
18(1/3)^2 = a = 2 . . . . multiply by (1/3)^2
The equation is ...
f(x) = ab^x
f(x) = 2(1/3)^x
