Which function represents a reflection of f(x) = Three-eighths(4)x across the y-axis? g(x) = NegativeThree-eighths (one-fourth)

nignag [31]

The function which represents a reflection of f(x) is

g(x) = Three-eighths $(4)^{-x}$ ⇒ last answer

Step-by-step explanation:

Let us revise the reflection across the axes

If the function f(x) reflected across the x-axis, then its image is g(x) = - f(x)
If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x)

∵ Three-eighths = $\frac{3}{8}$

∴ $f(x)=\frac{3}{8}(4)^{x}$

∵ f(x) is reflected across the y-axis

- That means the sign of x coordinates of the points on the graph will

change to opposite

∴ x will change to -x

∴ $g(x)=\frac{3}{8}(4)^{-x}$

The function which represents a reflection of f(x) is

g(x) = Three-eighths $(4)^{-x}$

The mayor of a town places a map of the town on a coordinate grid with Town Hall at the point (0,0) and with each unit represent

Lorico [155]

Answer:

Given that the question rightly asks the amount it cost to drive from Smithville to Jones City, we have;

The question rightly asks the amount it cost to drive from Smithville to Jones City is approximately $7.209

Step-by-step explanation:

The coordinates of Smithville is (-25, 10)

The coordinates of Jones City is (15, 12)

The cost of driving a car for a mile = $0.18

Therefore, the distance from Smithville to Jones City is given by the formula for the distance, l, between two points with coordinates as follows;

$l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}$

Where;

(x₁, y₁) = (-25, 10) and (x₂, y₂) = (15, 12)

$l = \sqrt{\left (12-10 \right )^{2}+\left (15-(-25) \right )^{2}} = 2 \cdot \sqrt{401}$

The distance from Smithville to Jones City = 2·√401 ≈ 40.05 miles

The amount, A, it cost to drive from Smithville to Jones City a distance of approximately 40.05 miles is therefore given as follows;

A = 40.05 miles × $0.18 ≈ $7.209

Determine whether each pair of triangles is similar. If similarity exists, write a congruency statement relating to the two tria

taurus [48]

To be similar ratios of the corresponding sides should be constant.

|UV|/|EO| = 8/4=2/1

|VL|/|OG| = 4/2=2/1

|LU|/|GE| = 6/3 = 2/1

So,all three corresponding pair of these triangles UVL and EOG are in proportion, so ΔUVL and ΔEOG are similar.

Because ΔUVL and ΔEOG are similar, their corresponding angles are congruent.

m∠U=m∠E

m∠V=m∠O

m∠L=m∠G.
