Determine the angle of elevation if the slope is 0.3415
miv72 [106K]

Using the slope concept, considering it's value of 0.3415, it is found that the angle of elevation is of 18.86º.

<h3>What is a slope?</h3>

The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

Hence, we have that:

\tan{\alpha} = 0.3415

\alpha = \arctan{0.3415} = 18.86^\circ

Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. X
chubhunter [2.5K]

Answer:

(15, 11).

Step-by-step explanation:

Given the system of equation;

X=2y-7 ..... 1

4x+y=71 ....2

Substitute 1 into2;

4(2y-7) + y = 71

8y - 28 + y = 71

9y - 28 = 71

9y = 71 + 28

9y = 99

y = 11

Substitute y = 11 into 1;

x = 2y - 7

x = 2(11)-7

x = 22-7

x = 15

hence the solution to the equation is (15, 11).

Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.
oksian1 [2.3K]

Answer:

-3 is the value of k in g(x)=kf(x)

Step-by-step explanation:

Both functions cross nicely at x=-3 so I'm going to plug in -3 for x:

g(x)=kf(x)

g(-3)=kf(-3)

To solve this for k we will need to find the values for both g(-3) and f(-3).

g(-3) means we want the y that corresponds to x=-3 on the curve/line of g.

g(-3)=-3

f(-3) means we want the y that corresponds to x=-3 on the curve/line of f.

f(-3)=1

So our equation becomes:

g(-3)=kf(-3)

-3=k(1)

-3=k

So k=-3.
