Find the side of a right triangle

lisabon 2012 [21]

The 2 sides of the right triangle is 25 and 24.

Any multiple of a Pythagorean triple is also considered a Pythagorean triple. Multiplying 3, 4, 5 by 2 gives 6, 8, 10, which is another triple. To see if a set of numbers makes a Pythagorean triple, plug them into the Pythagorean Theorem.

3,4,5 5,12,13 7,24,25 8,15,17 9,12,15

Final Result: 25,24

Answer:

<h2>The function is</h2><h2> $D(t) = 100 \times( \frac{40}{100} )^{t}$ </h2>

Step-by-step explanation:

At t = 0 the difference is 100 degree celsius.

After one second the temperature difference will be $100 - \frac{100\times60}{100}$ = $100(1 - \frac{60}{100} )$

After two second, the difference will be $100(1 - \frac{60}{100} )(1 - \frac{60}{100} ) = 100(1 - \frac{60}{100} )^{2}$

Hence, it can be written that,

$D(t) = 100 \times(1 - \frac{60}{100} )^{t}$ = $100 \times( \frac{40}{100} )^{t}$

Find the volume of the oblique prism.

coldgirl [10]

Formula for the volume of the oblique prism is:

$V=A_{\text{base}}\cdot H$ .

From the diagram H=12 units and the base is isosceles triangle with lengths of the sides 5, 5 and 6 units.

1. Find the length of the altitude h to the largest side. In isosceles triangle the altitude to the base is also the median, so it divides the base into two equal parts. By the Pythagorean theorem,

$h^2+3^2=5^2,\\ h^2=25-9=16,\\ h=4$ .

2. The area of the base is given by formula

$A_{\text{base}}=\dfrac{1}{2} a\cdot h=\dfrac{1}{2}\cdot 6\cdot4=12$ sq. un.

Thus, the volum is V=12·12=144 cubic units.
