Answer:
Step-by-step explanation:
a² + b² = (a + b)² - 2ab
Odd function must pass through origin so first two options are not correct.
Odd function must be rotational symmetry around origin. So last option is not correct.
So answer is C.
Part A:
Company A: $7 per hour +$30 service charge =money spent
Company B: $8 per hour +$40 service charge =money spent
Part B:
Company A: $7(8)+$30 = $86
Company B: $8(8)+$40 = $104
Part C:
Company A: $7(2)+$30 = $44
Company B: $8(2)+$40 = $56
You would save $12 if you use Company A instead of Company B's truck rental.
Answer:
3.
C. The domain is (1,+[infinity]) and the range is (-1,+[infinity])
4.
B. 6
5.
A. (-[infinity], 3)
Step-by-step explanation:
The Linear function has one independent and one dependent variable. The value of dependent variable can be found by taking the equation equals to 0. The domain function is set to analyse the range. The range can be set as -1 to 1. Any number between this is acceptable but outside this is not considered in the domain.
Area of triangle = 1/2(4)(4) = 16/2 = 8
if Area of square then A = 4 x 4 = 16
so answer
B. it's one half the area of square of side length 4 units
