Answer:

Radical: 5√13

Decimal: 18.0

Step-by-step explanation:

Given the dimension of the board given as 10ft by 15ft

If the board is nailed diagonally, the length of the bracing board will be gotten using the pythagoras theorem;

d² = 10² + 15²

d² = 100 + 225

d² = 325

d = √325

Expressing in radical form;

d = √325

d = √25*13

d = 5√13

Hence the length of the board in radical form is 5√13 feet

Express in decimal form;

d = √325

d = 18.0

Hence the length of the board to the nearest tenth is 18.0 feet

The polygons are similar. Find the value of x and y.
harina [27]

Answer:

x = 9, y = 27

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{x-1}{6} = \frac{16}{12} ( cross- multiply )

12(x - 1) = 96 ( divide both sides by 12 )

x - 1 = 8 ( add 1 to both sides )

x = 9

Also

\frac{y+1}{21} = \frac{16}{12} ( cross- multiply )

12(y + 1) = 336 ( divide both sides by 12 )

y + 1 = 28 ( subtract 1 from both sides )

y = 27

Describe whether the equation y-3x=7 is a function
Gala2k [10]

y - 3x = 7

can be written as

y = 3x + 7

For every value of x there is a unique value of y.  For example when x = 0 y = 3(0) + 7 = 7

Yes it is a function.

In particular it is a one-to-one function.
