Answer:
Step-by-step explanation:
∵A= l×b
⇒A= 4ab^2 × 6a^2b
⇒A= 24a^2b+1×b^2
Explanation: When multiplying indices, add the exponents of similar bases (that is, a^2×a = a^2+a^1 =a³) thus a^2b+1.
I hope this helped.
I think it's 27.6 miles in 1 hour, since if you divide 360 and 13, you'd have remainders for the miles.
Answer:
B) f(x) = -1 if x ≤ 0
2 if x > 0
Step-by-step explanation:
B) f(x) = -1 if x ≤ 0
2 if x > 0
The line passes through (0, -3)
Its perpendicular to another line whose slope is 2
The slope of the line therefore is -1/2 = -0.5 (the product of slopes two perpendicular lines is -1)
Taking another point (x,y) on the line;
Slope = change in y-axis ÷ change in x-axis
-0.5 = (y - -3) / (x - 0)
y = -0.5x - 3
