Log3 9 = 2 will be answer

For the given expression, 3^2 = 9, log3 9 = 2 will be the logarithmic equation.

As according to formulas of logarithm,
if, logx y = n
then x^n = y

so using this formula,
log3 9 = 2 will be the logarithmic equation of the given expression, 3^2 = 9

Help with those three please!!

Scilla [17]

Answer:

Part 1) Option A. The axis of symmetry is x=4

Part 2) Option C. minimum

Part 3) Option A. (4,-4)

Part 4) Option B. (2,0) and (6,0)

Step-by-step explanation:

we have

$f(x)=x^{2}-8x+12$

Part 1) What is the axis of symmetry of the parabola described by the equation above?

we know that

The equation above is a vertical parabola open upward

The axis of symmetry is the x-coordinate of the vertex

Find the vertex of the parabola (convert the equation in vertex form)

$f(x)-12=x^{2}-8x$

$f(x)-12+16=x^{2}-8x+16$

$f(x)+4=x^{2}-8x+16$

$f(x)+4=(x-4)^{2}$

$f(x)=(x-4)^{2}-4$ ----> equation in vertex form

The vertex of the parabola is (4,-4)

The axis of symmetry is x=4

Part 2) The vertex of the equation above is also

we know that

The equation above is a vertical parabola open upward

therefore

The vertex is a minimum

Part 3) What is the vertex of the parabola described by the equation above

we know that

The equation of the parabola into vertex form is equal to

$f(x)=(x-4)^{2}-4$

therefore

The vertex of the parabola is (4,-4)

Part 4) What are the x-intercepts of the parabola described by the equation above

we know that

The x-intercepts are the values of x when the value of y is equal to zero

$f(x)+4=(x-4)^{2}$

f)x)=0

$4=(x-4)^{2}$

take square root both sides

$(x-4)=(+/-)2$

$x=4(+/-)2$

$x=4(+)2=6$

$x=4(-)2=2$

therefore

The x-intercepts are

(2,0) and (6,0)

Find the value of the lettered angles in these diagram

Sedaia [141]

Answer:

1. m = 65°

x = 30°

2. x = 40°

Step-by-step explanation:

1. Since the figure is an isosceles triangle, m = 2x - 5

180 - 50 = 130 (Total degree for both m and 2x - 5)

130 ÷ 2 = 65 (m and 2x - 5 angle degrees)

65 - 5 = 60 (2x)

2 x = 60°

x = 60 ÷ 2 = 30°

2. I forgot the parallel rule for question 2, but I think X and 40° is parallel to each other?
