You haven't shared "the two patterns below."

Let me guess:  5+5 = 10 and 10+15 = 25.  Thus, 5+5+10+15 = 10+25 = 35.
If this is not correct, please ensure that you have shared this problem accurately and completely.

assuming the scale is by 1,

a) the slope is rise/run so it rises 3 units and moves 4 units right therefore the slope is 3/4

b) the y intercept is where the line crosses the y axis so by looking at the graph you can tell that the y int is 1

c) and the equation is made up of the slope and the y intercept: y= 3/4x + 1

Cos2A is equivalent to: A. sin2A−cos2A B. sin2A+cos2A C. cos2A−sin2A D. cosA−sinA
valina [46]

Formatted Options:

A. sin²A−cos²A

B. sin²A+cos²A

C. cos²A−sin²A

D. cosA−sinA

Answer:

C. cos²A−sin²A

Step-by-step explanation:

From the double angle formulas, we know that:

cos (A + B) = cosAcosB - sinAsinB

So, if B = A, then the above equation becomes;

cos(A + A) = cosAcosA - sinAsinA      [i.e replacing B with A]

=>cos(2A) = (cosA)² - (sinA)²

=> cos(2A) = cos²A - sin²A

Therefore,

cos(2A) is equivalent to cos²A - sin²A

Six years ago annabelle was twice as old as jason was. now, annabelle is four years older than jason. how old is jason now?
baherus [9]
Now: a=j+4
6 years ago: Anabelle: a-6; Jason: j-6

a-6=2(j-6) \\ a=2j-12+6 \\ a=2j-6 \\  \\ j+4=2j-6 \\ 4+6=2j-j \\ j=10 \\  \\ a=2(10)-6 \\ a=14
