Hello Guys, I really need help with these questions. Here they are.

Mathematics
1 answer:
valentina_108 [34]2 years ago
7 0

Step-by-step explanation:

Ok, so first...

a) if x is positive, it will remain x, so *x<7*

b) if x+3 is positive, it will be x+3<9 but you have to simplify it so you subtract 3 on both sides and get *x<6*

c) if y-8 is positive, it will stay like that, and you then add 8 on both sides to get *y>19*

g) if 3x-1 is positive, it will be 3x-1 greater than or equal to 18. add 1 on both sides and *3x > or = to 18*

4y+3 < or = 13. subtract 3 on both sides and you get *4y < or = 13*

One more thing:

Less than or equal to is a '<' with a line underneath.

Greater than or equal to is a '>' with a line underneath.

The lateral surface area S of a right circular cone is given by (equation given below). What radius should be used to produce a
Dima020 [189]
Given:
Lateral Area = π * r * (√h² + r²)

Lateral Area = 100 in² ; height = 5 in

I find it hard to derive the formula of r because of the radical sign. So, I'll just plug each radius to the formula to check confirm the given lateral area.

a) r = 1.52138 ⇒ LA = 24.98
b) r = 4.658 ⇒ LA = 100 
c) r = 78 ⇒ LA = 19152.68
d) r = 6.7432 ⇒ LA = 177.84

The radius is B.) r = 4.658 inches
