Answer:
Positive 3/4
Step-by-step explanation:
TO find perpednicular you take the negative reciprical of the slope, so the reciprical of -4/3 is -3/4, now add the negative to get - - 3/4 or 3/4
Answer: y= -2x/3 -3
Step-by-step explanation:
Substitute the x and y values from the given coordinate into the slope-intercept formula and solve for b
y = mx + b
-1 = -2/3(-3) + b
-1 = 2 + b
-1 -2 = b
-3 = b The y-intercept is -3
the equation: y = -2x/3 - 3
Answer:
the 30% off is better because 30% of 55 is 16.5 and the coupon is for 15 so the 30% off is better.

Answer:
3.84m
Step-by-step explanation:
If the scale for this Water tower is 1 : 12 then this means that for every 1cm of the model, the actual water tower has 12cm. Therefore, in order to find the actual depth of the water tower we first need to multiply the depth of the model by 12.
32cm * 12 = 384cm
1 cm is equal to 0.01 m , therefore we now have to multiply the depth of the actual water tower which is in cm by 0.01 to get the actual depth in meters
384 * 0.01 = 3.84m
A=78.54
A=1
/4πd2=1
/4·π·10^2≈78.53982m²
Hope this helps
