Answer:
Step-by-step explanation:
surface area=2×1/2×10×12+2×1/2×2×13+10×2
=120+26+20
=166 square units
Step-by-step explanation:
The function is given by
It is an absolute value function which has a v- shaped graph.
The vertex form of an absolute function is given by y = a|x-h| +k, where (h,k) is the vertex.
Comparing the given equation with this, we have
h = 12
k = -2
Hence, the vertex would be (12,-2).
Now, the range of the function is the set of y values for which the function is defined.
This function has vertex of (12,-2). hence, it would not take any values which are less than -2. Please see the attached graph.
Hence, the range would be the all y values greater than or equal to -2.
Hence, the range is given by
Answer:
<h2>
4.5 cm</h2>
Step-by-step explanation:
L = 2×π×r
9π cm = 2πr
9 cm = 2r
r = 4.5 cm
