Answer:
f(5) = 17
Step-by-step explanation:
f(x) = 3x + 2
f(5) = 3(5) + 2
f(5) = 15 + 2 = 17
30 + (40 × 3) = 150
60 + (30 × 3) = 150
in three months the total cost would he the same.
Answer:
a
Step-by-step explanation:
Hello,
Let 's n the number of sides,
R the radius of the circonscrit circle,
c the side of the polygon (c like côté)
Angle in the center is 360/n and its half is 180/n
(c/2)/R=sin(180/n)
Inside angles are (180-360/n)/2 = 90-180/n (°)
Answer:
33%
Step-by-step explanation:
The area of a circle is
, where r is the radius. In this case, the area of the second largest circle is
(because the radius is 3 + 4 = 7) = 49
.
The area of the smallest circle is
= 16
.
Now, the area of the shaded region is just the smallest circle's area subtracted from the second-largest circle's area:
49
- 16
= 33
To find the percentage of the logo that is shaded, we need to find the total area, which is just the area of the largest circle: 
Now, we just divide 33
by 100
to get:
33
/100
= 33/100 = 33%, which is our answer.
