47_6
because 61_4 plus 42_3 equal 103_7
now subtract 103_7 and 151_3
you get 47_6 which are the hours he practiced on the third week

If (he)={(0,1),(2,3),(-4,1)}, find h^-1(x)
ololo11 [35]

The given function is

h(x) = \{ (0,1), (2,3), (-4, 1) \}

The inverse function is

h^{-1}(x) = \{ (1,0), (3,2), (1,-4)\}

To get the inverse, we swap each x and y coordinate.

The rule is (x,y) \to (y,x)

So that's why the point (0,1) becomes (1,0) for instance.

Answer:

C

Step-by-step explanation:

Using the pythagorean theorem, we can determine if these are right triangles or not.

equation: sqrt a^2+b^2=c

this means the square root of the two shortest sides squared must equal to the largest side, (the hypotenuese).

Work for C:

What is the value of x and y?
ladessa [460]

Answer:

x=16 and y=9

Step-by-step explanation:

2y+30=3y+21[Diagonals of parallelogram are equal]

30-21=3y-2y

y=9

3y=2x-5[Diagonals of parallelogram are equal]

3×9=2x-5

27=2x-5

2x=27+5

x=32/2=16

The can is 12cm high and 8cm in diameter. Using formula V=TT r2h, how much is in the can
scoray [572]
The formula you have given here is for the volume of a cylinder. It should read V =  \pi r^{2} h.
First, to find r, the radius, divide the diameter by two (since the radius is the distance from the circumference to the centre and the diameter is the distance from any point on the circumference to the opposite point (through the centre))

r = 8/2 = 4

Now we can calculate this.
V =  \pi *4^{2}*12 =  \pi * 16 * 12 = 603.185... \\ 
V = 603 cm^{3}

If your answer needs to be in litres, one cubic centimetre = one millilitre.

603 cm3 = 603mL = 0.603 L
