Answer: C. is the right answer.
Step-by-step explanation:
Given: The cost of a chessboard at Odyssey Gifts is $6.
The function F(x) = 6x gives the cost of x chessboards.
Since x is the number of chessboards, thus the domain of the function should be the set of whole numbers.
Therefore, Domain= {0,1,2,3,4,5,....................}
when we put the values for x from the domain in the function we get values multiples to 6.
therefore range of the function={0,6,12,18,24,30,......}
Hence, C is the right option.
The number in exponential form should have an exponent of 3 so x^3 equals 3^3 (3×3×3=27). Since the exponent is the same, set the bases equal. Answer: A. X=3
Answer:
70
Step-by-step explanation:
another angle is 150 - 130 degree
so look at the triangle
we know x + 90 + 20 = 180 degree
so x = 70 degree
Answer:
66.91 km^2
Step-by-step explanation:
This answer will be long:
Interior angles of hexagon sum to (4)(180) = 720 each is 120 degrees
each side is 24/6 = 4 km
area of hexagon = 12 * 1/2 2 * (2 tan60) =<u> 41.5692 km ^2 </u>
L triangle 5 = hypot leg1 = 4 leg2 = 3 area = 1/2 * 3 * 4 =<u> 6 km^2</u>
TOP triangle is 4 = hypot leg1 = 3.464 leg2 = 2
area = 1/2 * 3.464 * 2 = <u>3.464 km^2</u>
R triangle two legs = 4 area = 1/2 * 4 x 4 =<u> 8 km^2 </u>
BOTTOM triangle two sides = 4 use sin rule sin40/4 = sin 100/x
third side = 4/sin 40 * sin 100 = 6.1284 km
semi perimter = ( 4 + 4 + 6.1284) / 2 = 7.0641 km
Use Herron's rule for area =
sqrt ( 7.0641 (7.0641-4)(7.0641-4)(7.0641-6.1284) ) =<u> 7.878 km^2 </u>
<u> add all of the areas to get 66.91 km^2 (IF I made no math errors!) </u>
