Y²-y¹ / x²-x¹

y²= 4, y¹= -1  x²=8, x¹=2

4-(-1) / 8-2              negative*negative = positive

=5/6

as an integer you'll have to multiply by the reciprocal

5/6* 6/5 = 1

Assuming we need to find i such that 
1 ≤ i ≤ n  and t[i]=i.

If we need to find only the first occurrence, we can do:

for i:1 to n {
    if t[i]=i then return(i)
}

If exhaustive search is required, then put the results (values of i) in an array or a linked list, return the number of values found, and the array (or linked list).

If the edge length of a cube is 11 feet, what is the correct way to write the expression to represent the volume of the cube in
satela [25.4K]

Answer:

(11 ft)³

Step-by-step explanation:

Given the shape is a cube, all of its sides are the same.

The formula for the volume of a cube is V = s³ where "s" represents the edge length.

Substitute "s" for 11 ft.

V = s³

V = (11 ft)³

In exponential form, do not solve for the volume. Leave the expression as

(11 ft)³

Without the units, the answer is 11³

A child’s building set contains a brick with dimensions 63 x 31 x 18mm . Assume this brick is a replica of a real brick that has
TEA [102]

The surface area and volume of the real brick will be 983.2 cm²and 1738.11 cm³ respectively.

<h3>What is volume?</h3>

The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.

The scale factor is ;

r = 630 cm /23

r = 27

L = 23 cm

b = 310 / 27 = 11.48 cm

h = 180/27 = 6.6 cm

The surface area of the brick;

A = 2(lb+bh+hl)

A = 2( 23 ×11.48+11.48×6.6+6.6×23)

A= 983.2 cm²

The volume of the brick is;

V= lbh

V=23 × 11.45 ×6.6

V=1738.11 cm³

Hence the surface area and volume of the real brick will be 983.2 cm² and 1738.11 cm³ respectively.
