Answer:94 m^2
Step-by-step explanation:
surface area equation for rectangle is 2*(a*b + a*c + b*c)
where a=4 b=5 and c=3
so substitute in all numbers and get:
Surface Area = 2×(4×5 + 4×3 + 5×3)
do the maths and got a solid 94 meters
(I squared because in this equation you are multiplying numbers that equal the area of a surface and not the whole volume which would be cubed)
<span>Using the formula above, your merit increase will be 2.5%. You received a score of 3.4 on your annual review. Since the merit increase model is 0.5% salary increase at a score of 2.6, with an additional 1% for every .4 points above that baseline, you get 2.5%, which is the baseline of 0.5% + 2% for the 0.8 points you scored above that baseline.</span>
Answer:
B
Step-by-step explanation:
Reminder: slope-intercept form is y=mx+b where m is the slope and b is the y intercept
There are two points given on the line: (-1, 2) and (1, -4)
First, find the slope
Reminder: slope is y2-y1/x2-x1
Substituting the numbers into the equation gives -4-(-2)/1-(-1) which would make m=-3
Now that the slope is found, we can use slope point form
Reminder: slope point form is y-y1=m(x-x1)
Substituting the numbers would give this equation:
y-2=-3(x-(-1))
Simplifying the equation would give y=-3x-1.
