Which function has the same rate of change as fx= 3x+5

alexandr1967 [171]

Answer:

Step-by-step explanation:

The rate of change is defined as the derivative of the function, or also known as the slope. The derivative here would be 3. Another function which has the same rate of change would be any function with a slope of 3. A few example are:

f(x) = 3x + 1

f(x) = 3x + 2

In the figure below, PDW and WTC are right triangles. The measure of WPD is 30°, the measure of WC is 6 units, the measure of WT

aliya0001 [1]

Answer:

PD = 12 $\sqrt{3}$

Step-by-step explanation:

Using the tangent ratio in right Δ PDW and the exact value

tan30° = $\frac{1}{\sqrt{3} }$ , then

tan30° = $\frac{opposite}{adjacent}$ = $\frac{WD}{PD}$ = $\frac{12}{PD}$ = $\frac{1}{\sqrt{3} }$ ( cross- multiply )

PD = 12 $\sqrt{3}$
