Need a bit of help with this question:
DiKsa [7]

Firstly let's find hypotenuse(let it will be "n" of smaller triangle

Let use Pythagorean theorem

a^{2}  +  {b}^{2}  =  {n}^{2}  \\  {20}^{2}  +  {10}^{2}  =  {n}^{2}  \\  n =  \sqrt{500}

Now we need to find hypotenuse(x) of bigger triangle

{c}^{2}  +  {n}^{2}  =  {x}^{2}  \\  {9}^{2}  +  { \sqrt{500} }^{2}  =  {x}^{2}  \\ x =  \sqrt{581}

The value of x must be rounded to 1 DP, so

\sqrt{581}  = 24.1039... \\  \sqrt{581}  \simeq \: 24.1

Answer: x=24.1

Identify the value of a if
Serga [27]

Answer:

a=1/3

Step-by-step explanation:

from the point on the graph

x=4 and y=8

substitute them into the equation:

y=a(x-2) (2x+4)

you will get

8=a(4-2) (2(4)+4)

8=a(2) (8+4)

8=a(2) (12)

8=2a×12

8=24a

divide both sides by 24

8/24=24a/24

1/3=a or a=1/3
