Answer:

The answer to your question is: Area = 30 ft²

Step-by-step explanation:

Data

Right triangle

base = 6 ft

height = 10 ft

hypothenuse = 11.7 ft

Area = (base x height) / 2

Process

Area = (6 x 10) / 2

Area = 60/2

Area = 30 ft²

Volgvan
I would like to say 44, but Im not positive.
But, 44x25% would equal 11. And 44-11(aka 25%) would equal 33.

You may want to double check my work though. Hope this helps

The mass of the particles that a river can transport is proportional to the sixth power of the speed of the river. A certain riv
Gelneren [198K]

Answer:

v_2 \approx 1.12246\ m.s^{-1}

v_{10}\approx 1.4678\ m.s^{-1}

v_{100}\approx 1.4678\ m.s^{-1}

Step-by-step explanation:

Mass of particles that a river can transport, m\propto\ v^6

where:

v = velocity of river flow

When v=1\ m.s

then the mass transported, m \propto 1^6

<u>When mass is twice:</u>

v=\sqrt[6]{2}

v_2 \approx 1.12246\ m.s^{-1}

<u>When mass is 10 times:</u>

v=\sqrt[6]{10}

v_{10}\approx 1.4678\ m.s^{-1}

<u>When mass is 100 times:</u>

v=\sqrt[6]{100}

v_{100}\approx 1.4678\ m.s^{-1}

How would you do number 12 and 15?
Gnesinka [82]

Answer:

x_1=x_2=-\dfrac{2}{3}

Step-by-step explanation:

For the quadratic equation ax^2+bx+c=0 the discriminant is defined as

D=b^2-4ac

and the quadratic formula for the roots gives us two roots:

x_1=\dfrac{-b-\sqrt{D}}{2a}

and

x_2=\dfrac{-b+\sqrt{D}}{2a}

For the equation 9x^2 +12x+4=0 use quadratic formula to find roots:

D=12^2-4\cdot 9\cdot 4=144-144=0

So,

x_1=x_2=\dfrac{-12\pm \sqrt{0}}{2\cdot 9}=-\dfrac{12}{18}=-\dfrac{2}{3}
