Step-by-step explanation:
3900 = Σ 
400 - 20*(n - 1)
Step-by-step explanation:
<u>Product property</u>
- If the bases are the same, you don't multiple them. However, if they are the same, you do multiple for example : (2³ * 2¹ = 2⁴.when the bases are the same) (2³ * 3¹ =6⁴. When the bases are not the same
- We add the index.
<u>Quotient</u><u> </u><u>property</u>
- Same here, if the bases are the same, they stay the way they were
- We subtract the index
<u>Power</u><u> </u><u>property</u>
- Here we multiple the index because of the bracket for example : (9²)²= 9⁴
<u>Negetive</u><u> </u><u>exponent</u><u> </u><u>property</u>
- When ever the index has a negative sign its convected to a fraction, for instance : 9¯² = 1 /9²
- Note, when it turns to a fraction th index becomes positive
I am not a hundred percent sure but I think it is A
Hope this helps:)
In looking at it I would guess it is asking which of the points is on the line? To answer that you would have to take each point an plug it into the equation and see if it is true.
3x - 7 = y
A(9,20)
3(9) - 7 = 20
27 - 7 = 20
20 = 20 True - this point is on the line
B(5,0)
3(5) - 7 = 0
15 - 7 = 0
8 = 0 False - this point is not on the line
C(3,2)
3(3) - 7 = 2
9 - 7 = 2
2 = 2 True - this point is on the line
I hope this helps
Answer:
Sin, Cos, Tan and others are used to calculate the ratios of the sides of a right angled triangle by taking a certain angle as the angle of reference.
On the other hand, Sin‐¹, Cos‐¹ and Tan-¹ are used to find the reference angle used to calculate the ratio of sides.
For this question,
we need to find which option should used to calculate the angle the slide makes with the vertical support.
So the option will have to be either A, C or E.
here, the base is 2.81m and hypotenuse is 3.64m.
we know, Cos = base / hypotenuse
So the angle is given by Cos-¹(2.81/3.64)
Option C
