Answer:
1
Step-by-step explanation:
Two distinct points define exactly one line.
___
We haven't seen the figure. If R and S are the same point, an infinite number of lines will pass through R and S.
Maria started with 37 boxes.
Given:
7 boxes bought
half of the boxes were destroyed in the fire.
22 boxes left
Find the beginning number of boxes.
Let x be the beginning number of boxes.
(x + 7)/2 = 22
2((x+7)/2) = 2(22)
x + 7 = 44
x = 44 - 7
x = 37
To check:
x + 7 = 37 + 7 = 44
44 * 1/2 = 22
22 = 22
Answer:
88 Miles
Step-by-step explanation:
64-20=44 44/.5=88
A quadrilateral is a shape that has four equal sides.
For example: squares, rectangles, parallelogram
A parallelogram is a quadrilateral with 2 pairs of parallel sides.
A square can't be in the hierarchy under trapezoids, rectangles,or rhombus.
Answer:
you're not doing anything wrong
Step-by-step explanation:
In order for cos⁻¹ to be a function, its range must be restricted to [0, π]. The cosine value that is its argument is cos(-4π/3) = -1/2. You have properly identified cos⁻¹(-1/2) to be 2π/3.
__
Cos and cos⁻¹ are conceptually inverse functions. Hence, conceptually, cos⁻¹(cos(x)) = x, regardless of the value of x. The expected answer here may be -4π/3.
As we discussed above, that would be incorrect. Cos⁻¹ cannot produce output values in the range [-π, -2π] unless it is specifically defined to do so. That would be an unusual definition of cos⁻¹. Nothing in the problem statement suggests anything other than the usual definition of cos⁻¹ applies.

This is a good one to discuss with your teacher.
