Answer:
M of aftershock = 4.90
Step-by-step explanation:
5.6 = log(x/1)
1/5 * 398,107.1 = 79,621.4
79,621.4
m = log (79,621.4) = 4.90
D. 93 x 95; 8835 ft
A rectangle has four sides: 376/4 = 94
94 the average measurement. It is not the exact measurement of each side because a polygon with four side with the same measurement is a square not a rectangle.
So the measure of the rectangles length can be more than 94 and the measure of the width is less than 94. The sum of the length and width should be 188.
Based on the choices. C is not an option. Its the area for a square.
A, B, and D are the remaining options but D has the greatest possible rectangular area.
Answer:
C
Step-by-step explanation:
The area (A) of the triangle is calculated using
A = 
ab sinC
where a, b are the 2 sides and C is the angle between them
here a = 9, b = 15 and C = 70°, hence
A = 0.5 × 9 × 15 × sin70° = 63.4 cm² → C
Step-by-step explanation:
the down function clearly is
y = x - 5, -2 <= x <= 8
the reasons :
1. it is linear. so, we have only a form of ax+b
2. x=0 => y=-5
x=5 => y=0
so, with these 2 points alone we can see
y = ax + b
-5 = a×0 +b = b
0 = a×5 - 5
5 = a×5
1 = a
the inverse function is based on
y = x - 5
=>
x = y + 5
now renaming the variables so that y is the result and x the input variable delivers
y = x + 5
and because the original function only delivered y- values between -7 and +3, this is also the defined domain for the inverse function.
so,
y = x + 5, -7 <= x <= +3
so, we have the points
x=-7 => y=-2
x=+3 => y=8
you need to draw the line between these 2 points with filled dots at the end points (as they are included in the function).
Answer:
18 miles
Step-by-step explanation:
One hour equals 60 minutes. 60 divided by 4 = 15
4 multiplied by 4.5=18. hope this helps
