Which best describes the range of the function f(x)=2/3(6)^x after it's been reflected over the x-axis
Norma-Jean [14]

The function 6^x is an exponential with base greater than 1. So, its range is (0,\infty), with 0 being the horizontal asymptote as x \to -\infty.

If you multiply the function by \frac{2}{3}, the range remains the same.

If you reflect it over the x-axis, you're changing the sign of the function. So, the new range is

(-\infty,0)

Write an equation of the line that passes through (1, −1) and is perpendicular to the line y=1/2x−3. An equation of the perpendi
lapo4ka [179]
Y = 1/2x - 3. Slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So the perpendicular line will have a slope of -2.

y = mx + b
slope(m) = -2
(1,-1)...x = 1 and y = -1
now we sub and find b, the y int
-1 = -2(1) + b
-1 = -2 + b
-1 + 2 = b
1 = b

so ur perpendicular equation is : y = -2x + 1

find the value of each variable in the circle to the right. the dot represents the center of the circle.
gladu [14]

We have been given an image of a circle. We are asked to find the value of each variable.

We can see that angle b corresponds to diameter of circle. We know that the measure of an angle that is inscribed to the diameter of a circle is 90 degrees . Therefore, the value of b will be 90.

we can see that angle is an inscribed angle of arc 99 degrees. We know that measure of an inscribed angle is half the measure of inscribed arc.

a=\frac{1}{2}\cdot 99

a=49.5

Therefore, the value of a is 49.5 units.

We know that measure of all angles of a triangle is 180 degrees. The measure of 3rd angle will be half the measure of c, so we can set an equation as:

a+b+\frac{1}{2}c=180

49.5+90+\frac{1}{2}c=180

139.5+\frac{1}{2}c=180

139.5-139.5+\frac{1}{2}c=180-139.5

\frac{1}{2}c=40.5

\frac{1}{2}c\cdot 2=40.5\cdot 2

c=81

Therefore, the value of c is 81.
