The function f(x) = 2x -3 is changed to f(x)+k. The new function f(x) can be represented by the graph below. What is the value o

OleMash [197]

As you can see in this picture we have a point on y- axis which is our y-intercept and f(x)
so first we should find what WAS the y-intercept before adding k
so we can say:
f(x) = 2(0) - 3 = -3
so it WAS -3 .... but in this picture is -7
so you have:
-3 + k = -7
k = -7 + 3 = -4
so k is equal to -4 :)))
i hope this is helpful

In ΔDEF, the measure of ∠F=90°, EF = 2.3 feet, and FD = 2.9 feet. Find the measure of ∠D to the nearest tenth of a degree.

Phoenix [80]

Answer:

$\theta=38.42 \textdegree$

Step-by-step explanation:

From the question we are told that:

Angle of F $\angle F=90 \textdegree$

Length of $EF = 2.3 feet,$

Length of $FD= 2.9 feet,$

Generally the equation for Angle D $\theta$ is mathematically given by

Since $\angle F=90$ .The triangle is a right angle Triangle

Therefore

$tan \theta=\frac{EF}{FD}$

$tan \theta=\frac{2.3}{2.9}$

$\theta=tan^{-1} 0.793$

$\theta=38.42 \textdegree$
