Answer:
f(5)=12
Step-by-step explanation:
Replace all x by 5
f(5)=3(5)-2
multiply 3 and 5 together
f(5)=15-2
Simplify:
f(5)=13

Step-by-step explanation:
The perimeter is the length of all 6 sides of the polygon.
Note that the 2 unknown sides are
8 - 4 = 4 mm and 8 - 2 = 6 mm
Starting with the left side
Perimeter = 8 + 2 + 4 + 6 + 4 + 8 = 32 mm
The polygon can be split into 2 rectangles.
The lower rectangle with sides of 8 and 4
and the upper rectangle with sides 2 and 4
Area = (8 × 4) + (2 × 4) = 32 + 8 = 40 mm²
Well how you doin corey!?
Im trying to find the answer too lol
Answer:
<h2>x = 12</h2><h2 /><h2>y = 4√3</h2>
Step-by-step explanation:
<u>To find x we use cosine</u>
cos∅ = adjacent / hypotenuse
x is the adjacent
8√3 is the hypotenuse
cos 30 = x / 8√3
x = 8√3 cos 30
<h3>x = 12</h3>
<u>To find y we use sine</u>
sin∅ = opposite / hypotenuse
y is the opposite
8√3 is the hypotenuse
sin 30 = y / 8√3
y = 8√3 sin 30
<h3>y = 4√3</h3>
Hope this helps you
Answer:
They averaged 3lbs. a week for 4 weeks to get 12lb. They would need an additional 36lbs. to get to 48lbs. Averaging the same 3lbs. per week, this would take an additional 12 weeks for a total of 16 weeks.
