Answer:
Step-by-step explanation:
<u>Given sequence:</u>
<u>This is AP with:</u>
- The first tern a₁ = - 3
- Common difference d = 3
<u>The rule for the nth term of the sequence is:</u>
<u>Substitute values:</u>
- aₙ = -3 + (n - 1)(3) =
- -3 + 3n - 3 =
- 3n - 6
Surface area of cone is a sum of surface of its base and surface of its mantle.
Surface of its base is a circle which surface we will calculate like this:
Sb = pi*r^2 where r is d/2
Sb = 201m^2
Surface of mantle we calculate by:
Sm = pi*l*r where l is length of side of cone.
l =
= 25.3
Sm = 635.8m^2
Total suface is:
Sb + Sm = 836.8m^2

There are 24 girls and every 4 to the 2 =6 groups 6x4
- The equivalent inequality for the number line is x < 8
- The equivalent inequality for the number line is x ≥-5
<h3>Inequality functions </h3>
The inequality expression is an expression not separated by an equal sign,
11) The equivalent inequality for the number line is x < 8. This shows that the values of x that make it true must be less than 8.
Note that the sign is less than because the circle is open and moves towards the left of the number line
11) The equivalent inequality for the number line is x ≥-5. This shows that the values of x that make it true must be greater than or equal to 8.
Note that the sign is greater than or equal to because the circle is closed and moves towards the right of the number line
