Given that MN = 5, NO = 12, and MO = 13, find cos O.

Galina-37 [17]

Answer:

12/13

Step-by-step explanation:

Given that MN = 5, NO = 12, and MO = 13, find cos O.

Since the reference angle is P, hence;

MN is the opposite = 5

MO is the hypotenuse = 13 (longest side)

NO is the adjacent = 12

Cos O = adj/hyp

Substitute the given values

Cos O = 12/13

Hence the value of Cos O is 12/13

Given the graph of y=f(x), shown as a red dashed curve, drag the movable blue point to obtain the graph of y=f(x−4)+3.

Sergeeva-Olga [200]

Answer:

See graph in attachment.

Step-by-step explanation:

The graph of $y=f(x)$ is a parabola that has its vertex at the origin.

The equation of the transformed graph is

$y=f(x-4)+3$

The vertex of this transformed function is

$(4,3)$

Drag the blue graph up so that the vertex will now be at (4,3).

Chris earns four times Vesna's wage v and Vesna earns $17 more than Dawn. How many dollars does Chris earn if their combined wag

guajiro [1.7K]

Call Dawn's wage x, we will have Vesna's wage = x + 17 and Chris' wage = 4x(x + 17). So we have the equation:
$x + (x + 17) + 4 \times (x + 17) = 163 \\ 2x + 17 + 4x + 68 = 163 \\ 6x = 78 \\ x = 13$
Therefore, Chris's wage:
$4 \times (13 + 17) = 120$
