Answer:
85/1
Step-by-step explanation:
because both numbers are divisible by 16
a² + b² = c²
40² + b² = 41²
b² = 41² - 40²
b² = 1681 - 1600
b² = 81
b = 9
slope (m) of asymptote =
y-intercept (b) = 0 since the center is at the origin
Answer: y = and y =
Using the general equation formula;
y-y1=m(x-x1)
y1=20 and x1=4
Since the two lines are perpendicular, they have the same gradients
But gradient for y=4x+5 is 4
Therefore m of the equation is 4
Substituting all this into the general formula;
y-20=4(x-4)
y-20=4x-16
y=4x-16+20
y=4x+4
Answer:
255.50
Step-by-step explanation:
If each day the number is doubled, then all you must do is keep on doubling to the ninth day and then add it all together
Answer:
-8
Step-by-step explanation:
When the temperature drops it goes into the negative, so the calculation would be -2 - -6
