Answer:
CB = sqrt (4a^2 + 6b^2)
Step-by-step explanation:
Using distance formula
d^2 = ( x1-x2)^2 + (y1-y2)^2
d^2 = (3a - -a)^2 + (b - -5b )^2
d^2 = (4a)^2 + (6b)^2

A. 3 tbsp per 2 tsp
b. 135 pitches per 45 strikes
c. 128 miles per 4 hours
Answer:
D -24/25
Step-by-step explanation:
sin(2x) = 2sin(x)cos(x)
cos(x) = ⅘
sin²(x) = 1 - cos²(x) = 1 - (⅘)²
sin²(x) = 9/25
sin(x) = -⅗
(Because 4th quadrant)
sin(2x) = 2(-⅗)(⅘)
= -24/25
