Answer:
In the scenario in which you have declared a numeric array named numbers, and two of its elements are numbers[1] and numbers[5] you know that numbers[1] is smaller than numbers[5] and that there are exactly three elements between those two elements. Correct answer: a and c.
numbers[i] is the element of the array called numbers
Step-by-step explanation:
Why is there a b) in the middle of the polygon? Question creators, proofread your figures.
a) Two triangles and a kite
Top triangle (1/2)(5.53)(1.5)
Bottom triangle (1/2)(6)(2)
The kite is like two triangles with shared base 2+3=5 and combined height 7,
(1/2)(5)(7)
Adding it up,
area = (1/2)(5.53)(1.5) + (1/2)(6)(2) + (1/2)(5)(7) = 27.6475
Answer: 27.6475 sq cm
b) Three triangles, including one right triangle
Area = (1/2) (6.7)(3) + (1/2)(6.2)(2.5) + 1/2(6.2)(2) = 24.
Answer: 24 sq cm
Answer:
![-7+5[(-5)^2+(-32)]=-42](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-42)
Step-by-step explanation:
First solve the sums that are within the parentheses.
Remember that if the numbers have equal signs then they are added and the same sign is placed.
If the numbers have different signs they are subtracted and the sign of the major is placed
So:
Then we have the following expression:
![-7+5[(-5)^2+(-32)]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D)
Remember that by multiplying signs you get:
(+) * (+) = +
(-) * (-) = +
(+) * (-) = -
(-) * (+) = -
Then:
![-7+5[(-5)^2+(-32)]=-7+5[(-5)*(-5) -32]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7%2B5%5B%28-5%29%2A%28-5%29%20-32%5D)
![-7+5[(-5)^2+(-32)]=-7+5[25 -32]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7%2B5%5B25%20-32%5D)
![-7+5[(-5)^2+(-32)]=-7+5[-7]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7%2B5%5B-7%5D)
![-7+5[(-5)^2+(-32)]=-7-35](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7-35)
