I have worked the answer to a which is 301.6 but I’m not too sure how you work out b any help would be much appreciated!
Greeley [361]

Answer:

188.5 cm^2

Step-by-step explanation:

a) Your volume is correct.

b) The curved surface area of the cone is called the lateral area.

Its formula is:

LA = (pi)rs,

where pi is 3.14159...

r = radius of the base

s = slant height of the cone

Here, r = 6 cm, and s = 10 cm

LA = (3.14159)(6 cm)(10 cm)

LA = 188.5 cm^2

Caculate the value of x on the figure below
Nady [450]

Answer:

x = 58

Step-by-step explanation:

The angle at the centre is twice the angle at the circumference subtended by the same arc, thus

x + 62 = 2(x + 2)

x + 62 = 2x + 4 ( subtract x from both sides )

62 = x + 4 ( subtract 4 from both sides )

58 = x

For what values of k the relation R:{(k2 , 5), (3k, 6)} is not a function?
n200080 [17]
<h3>Answer:  k = 0 or k = 3</h3>

Explanation:

If you have repeated x values, then you wont have a function. For example, the points (1,5) and (1,6) mean we don't have a function since the input x = 1 leads to multiple outputs y = 5 and y = 6 simultaneously. For a function to be possible, we must have any input lead to exactly one output only.

What we do is set the x coordinates (k^2 and 3k) equal to each other and solve for k

k^2 = 3k

k^2-3k = 0

k(k-3) = 0 .... factoring

k = 0 or k-3 = 0 .... zero product property

k = 0 or k = 3

If k = 0, then (k^2,5) becomes (0,5). Also, (3k,6) becomes (0,6). The two points (0,5) and (0,6) mean the graph fails the vertical line test.

Similarly, if k = 3, then (k^2,5) becomes (9,5) and (3k,6) = (9,6). Another vertical line test failure happens here to show we don't have a function.

What will be the result of substituting 2 for x in both expressions below? One-half x + 4 x + 6 minus one-half x minus 2 Both ex
Anit [1.1K]

Answer:

Both expressions equal 5 when substituting 2 for x because both expressions are equivalent

Step-by-step explanation:

Given

\frac{1}{2}x + 4 - Expression 1

x + 6 - \frac{1}{2}x - 2 -- - Expression 2

Required

Find the result of both expressions when x = 2

<em>Expression 1</em>

\frac{1}{2}x + 4

Substitute x = 2

\frac{1}{2} * 2 + 4

1 + 4

Result = 5

<em>Expression 2</em>

x + 6 - \frac{1}{2}x - 2

Substitute x = 2

2 + 6 - \frac{1}{2} * 2 - 2

2 + 6 -1 -2

Result = 5
