Answer:
Step-by-step explanation:
Given
<u>The arithmetic sequence </u>
- {aₙ} = {2.6, 4, 5.4, 6.8, 8.2, ...}
We can see the common difference is d = 1.4
<u>The formula for this sequence is:</u>
Answer:
A. 1/2.
Step-by-step explanation:
The ratio of the sides of a 30-60-90 triangle is 2:1:√3 where 2 is the hypotenuse. 1 is the shortest leg and √3 is the longest leg.
In the diagram we see that the longest leg is opposite the 60 degree angle.
So the longest leg is 3.5√x and the shortest leg ( from applying the ratios) = 3.5√x / √3.
and the hypotenuse is 2 * 3.5√x / √3 (using the ratios again).
So sin 30 = shortest leg / hypotenuse = 3.5√x / √3 / 2 * 3.5√x / √3
= 1/2.
Answer:
Step-by-step explanation:
Question 17
y-y1 = m (x-x1 )
so basically you plug in the (x,y) to y1 and x1 place
Remeber always times it by -1
so answer would be
y-2 = -1/3 (x+4)
Question 18
Pretend its 3x+2y =8
you need to find x or y first im going to find y first
so
- 2y = -3x +8
divide by 2 to isolate y
y = -3/2x - 4
plug it back into the equation
3x + 2(-3/2x) - 4
the x will cancel
so y= -4
Then
plug in the -4 in place of y
SO the Answer is YES because y is horizontal there is -4 = there will be (-3, -4)!
To find out how much Marie will save you have to multiply the 20% with the original praise which is $40.00. So we’ll change the 20% to 0.20 to multiply it with 40.
0.20 x 40 = 8
So Marie will save $8.00 using the coupon
