Answer:
The amount of steel used = 94.38 
Step-by-step explanation:
Height of the tank = 4.5 m.
Diameter of the tank = 4.2 m.
But,
radius = 
= 
radius = 2.1 m
Total surface area of a cylinder = 2
rh + 2

= 2
r(r + h)
= 2 x
x 2.1 (2.1 + 4.5)
= 44 x 0.3 (6.6)
= 87.12
Total surface area of a cylinder = 87.12 
Since
of the steel was wasted, then;
x 87.12 = 7.26 
Actual area of steel sheet used = 87.12 + 7.26
= 94.38 
Thus, 94.38
of steel was used in making the tank.
Answer:
one solution! & that would be be 57/10. hopefully that's correct.
Step-by-step explanation:
Answer: option c or 3 because you gotta take out the 6 so u do -6 which left is negative and right is positive and then get rid of the +2 exponent so up is positive and down is negative so you move -2 which is down.
Step-by-step explanation:
It'd be a lot easier to help you if you'd share the answer graphs.
Just so that you know:
<span>f(x) = log(x + 3) + 1 can be graphed as follows:
</span>
1. Graph y = log x. This function's domain is x>0. It begins in Quadrant IV and ends in Quadrant I. It intercepts the x-axis at (1,0).
2. Now move the entire graph 1 unit to the left. This gives you the graph of y = log (x+1).
3. Now translate this entire graph up 3 units. This gives you the graph of <span>f(x) = log(x + 3) + 1.</span>

See below
Step-by-step explanation:
Find the area of the triangular end : 1/2 base * height cm^2
then multiply that area by the length of the prism (10 cm)
to get volume in cm^3
