What is the length of the unknown leg in the right triangle?

Pythagorean theorem: ⇒ a²+b²=c²

A unknown leg of a right triangle can be found using the Pythagorean theorem.

a²+b²=c²

a²+9²=√113²

You had to solve by the equation with exponents.

And it gave us ⇒ a²+81=113

And then you had to subtract by eighty-one (81) from both sides of equation form.

And it gave us ⇒ a²=32

And finally you had to used their square root with thirty-two (32) from both sides of equation form.

And it gave us ⇒ a²=32, \sqrt{a^2}= \sqrt{32}, and a=\sqrt{32}.

<u><em>32 miles is the correct and final answer. </em></u>

Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

So for this, we will be using the pythagorean theorem, which is leg^2+leg^2=hypotenuse^2 , to find the missing leg. Since we know that a and 9 are our legs and √113 is our hypotenuse, plug them into the equation as such:

a^2+9^2=\sqrt{113}^2

Firstly, solve the exponents:

a^2+81=113

Next, subtract 81 on both sides of the equation:

a^2=32

Next, square root both sides of the equation:

a=\sqrt{32}

<u>Your final answer is √32 miles.</u>

Two particles travel along the space curves r1(t) = t, t2, t3 r2(t) = 1 + 2t, 1 + 6t, 1 + 14t . Find the points at which their p
GuDViN [60]

Answer:

A) points at which paths intersect : (1,1,1) ; (2,4,8)

B) DNE

Step-by-step explanation:

A) To find the points in which the particle paths intersect, it is necessary to find the values of t for which the three components of both vectors are equal:

t_1=1+2t_2\\\\t_1^2=1+6t_2\\\\t_1^3=1+14t_2

you replace t1 from the first equation in the second equation:

(1+2t_2)^2=1+6t_2\\\\1+4t_2+4t_2^2=1+6t_2\\\\4t_2^2-2t_2=0\\\\t_2(2t_2-1)=0\\\\t_2=0\\\\t_2=\frac{1}{2}

Then, for t2 = 0 and t2=1/2 you obtain for t1:

t_1=1+2(0)=1\\\\t_1=1+2(\frac{1}{2})=2

Hence, for t1=1 and t2=0 the paths intersect. Furthermore, for t1=2 and t2=1/2 the paths also intersect.

The points at which the paths  intersect are:

r_1(1)=(1,1,1)=r_2(0)=(1,1,1)\\\\r_1(2)=(2,4,8)=r_2(\frac{1}{2})=(2,4,8)

B) You have the following two trajectories of two independent particles:

r_1(t)=(t,t^2,t^3)\\\\r_2(t)=(1+2t,1+6t,1+14t)

To find the time in which the particles collide, it is necessary that both particles are in the same position on the same time. That is, each component of the vectors must coincide:

t=1+2t\\\\t^2=1+6t\\\\t^3=1+14t

From the first equation you have:

t=1+2t\\\\t=-1

This values does not have a physical meaning, then, the particle do not collide

answer: DNE

Se arrastra un bloque de 18 kg a través de una superficie con una fuerza de 300 N en donde el coeficiente de fricción de dicha s
ozzi

Answer:

10.9\ \text{m/s}^2

Step-by-step explanation:

m = Masa del bloque = 18 kg

F = Fuerza en el bloque = 300 N

\mu = Coeficiente de fricción = 0.6

El equilibrio de fuerzas del sistema viene dado por

F-f=ma\\\Rightarrow 300-0.6\times 18\times 9.81=18a\\\Rightarrow a=\dfrac{300-0.6\times 18\times 9.81}{18}\\\Rightarrow a=10.9\ \text{m/s}^2

La aceleración del bloque es 10.9\ \text{m/s}^2.
