Answer:

(-3,4)

Step-by-step explanation:

That means to reflect the point across the y-axis... If you draw (3,4) on the coordinate plane you should see (-3,4) is the reflection across the y-axis from that point.

Answer:

P' = (- 3, 4 )

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ), hence

P(3, 4 ) → P'(- 3, 4 )

A woman standing on a hill sees a flagpole that she knows is 65 ft tall. The angle of depression to the bottom of the pole is 14

Oliga [24]

Answer:

Let the distance between woman and pole be "x".

From diagram,

In ΔOAB,

tan 18 = $\frac{Perpendicular}{Base}$

tan 18 = $\frac{65 -y}{x}$

∴ x = $\frac{65 -y}{tan 18}$ ................ (1)

In ΔOBC

tan 14 = $\frac{Perpendicular}{Base}$

tan 14 = $\frac{y}{x}$

y = x × tan 14 ..............(2)

equating (2) in (1), we get;

x = $\frac{65}{tan 18 + tan 14}$

x = $\frac{65}{0.574}$

∵ tan 18 + tan 14 = 0.574

<em>i.e. The her distance from the pole is 113.2 ft.</em>

Two dice are rolled, and the sum of the face values is six. What is the probability that at least one of the dice came up a thre

gizmo_the_mogwai [7]

Answer : $P(\text{ atleast one of the dice come up 3})= \frac{1}{5}$

Explanation :

We know that ,

Sample space of " sum of faces is 6"= $\{(3,3),(4,2),(2,4),(5,1),(1,5)\}$

Atleast one of the dice come up 3 = $\{(3,3)\}$

So,

$Probability = \frac{\text{No. of favourable outcomes}}{\text{Total no. of outcomes}}$

$P(\text{ atleast one of the dice come up 3})= \frac{1}{5}$
