Answer:

a=0

Step-by-step explanation:

The given expression is;

(\frac{1}{7})^{3a+3} =343^{a-1}

This implies that;

7^{-1(3a+3)} =7^{3(a-1)}

Equate the exponents;

-1(3a+3) =3(a-1)

Expand;

-3a-3 =3a-3

-3a-3a =-3+3

-6a=0

a=0

<h2>Answer:</h2>

<u>The right choice is (2) </u><u>0</u>

<h2>Step-by-step explanation:</h2>

7 ^(3a-3) = 7^(3a-3)

= -3a -3 = 3a -3

= -3a = 3a

-3a -3a = 0

-6a = 0

a= 0

Which is an example x-intercept of the graph of the function y=tan(x-(5pi/6))
emmainna [20.7K]
Answer: x = 5π/6

Explanation:

1) Given function:

y=tan(x- \frac{5 \pi }{6} )

2) x-intercept are the roots of the function, i.e. the solution to y = 0

3) to find when y = 0, you can either solve the equation or look at the graph.

4) Solving the equation you get:

y = 0 ⇒ tan(x - 5π/6) = 0 ⇒ x - 5π/6 = arctan(0)

arctan(0) is the angle whose tangent is zero,so this is 0

⇒ x - 5π/6 = 0 ⇒ x = 5π/6.

Then, one example of an x-intercept is x = 5π/6, which means that when x = 5π/6, the value of the function is 0.

Since, the tangent function is a periodic function, there are infinite x-intecepts, that is why the questions asks for one example and not all the values.

You can verify by replacing the value x = 5π/6 in the given function:

y = tan (5π/6 - 5π/6) = tan(0) = 0.

Is 5, √50, 5 a right triangle
Fynjy0 [20]

Answer:

Yeah,its right angled traingle.

Reason:Suppose Root over 50 as hypotenuse and other two sides as base and perpendicular respectively.

By using pythagoras theorem

h^2=p^2+b^2

50=50(which is true)

Therefore it is right angled triangle..This is your required answer.

Find the points of Intersection of these graphs
geniusboy [140]

Answer:

the line crosses the parabola at (-2,4) and (3,9)

Step-by-step explanation:

y=x^2

y=x+6

set them equal to each other

x^2=x+6, now set it equal to zero

x^2-x-6=0, now find the root

(x+2)(x-3)=0, the x=-2, and x=3; now substitute into any of the equation to find the points where graphs intercept

at x= -2, y=(-2)^2=4, so one point is (-2,4)

at x=3, y=(3)^2=9, so other point is (3,9)

the line crosses the parabola at (-2,4) and (3,9)
