11. A ranger in a lookout tower spots two fires on the campground below. Fire Als 75 meters east

iogann1982 [59]

Answer:

The fire hydrant = 9 meters west and south of the tower = 58 m

Step-by-step explanation:

The coordinate as the origin includes the Fire A and Fire B

Given that

Fire A is 75 meters east and south of the tower is 40 meters

So, it is presented (75,-40)

And, the fire B is 37 west and south of the tower is 64 meters

So, it is presented (-37,-64)

Now at a point O (x,y) divides AB a line segment as A(x_1, y_1) and B(x_2, y_2)

So,

$x = \frac{n}{n+m} (x_2 - x_1) + x_1\\\\y = \frac{n}{n+m} (y_2 - y_1) + y_1$

Now it divides in three-fourth

So,

$x = \frac{n}{n+m} (x_2 - x_1) + x_1\\\\= \frac{3}{4} (-37-75) + 75\\\\= \frac{3}{4} (-112) + 75\\\\= -84 + 75\\\\= -9$

$y = \frac{n}{n+m} (y_2 - y_1) + x_1\\\\= \frac{3}{4} (-64-(-40)) + (-40)\\\\= \frac{3}{4} (-18) -40\\\\= -18-40\\\\= -58$

Hence, these two are to be considered

7.8number 14 please help it’s due in tomorrow and I really don’t want a detention

Delvig [45]

The filled in dot means inclusive and the hallow dot means exclusive. For an inequality, inclusive will mean it can be equal to that number as well as being less or greater than. Exclusive means the opposite.
In terms of x, the number line shows that -2 <= x < 2.

What is the equation of a line, in the general form, with a slope of-2an a y-intercept of 8? 1) x+2y-8=0, 2) 2x+y-8=0, 3) 2x-y+8

AlekseyPX

It is 3 but it is different a little bit because you need to move the y to the other side

Sound, earthquakes, the brightness of stars, and chemistry, such as pH balance, a measure of acidity and alkalinity, are all instances of this.

Please Help ASAP. Thanks.

Answer:

a = 2

Step-by-step explanation:

If M is the midpoint, 1/2 of FG = FM since FG is the whole length.

FG = 14a + 1

1/2 FG = 1/2(14a + 1)

1/2 FG = 7a + 1/2

The length of the segment FM = 14.5 and that is the same length as 1/2 FG

7a + 1/2 = 14.5

1/2 = 0.5

7a + 0.5 = 14.5 Subtract 0.5 from both sides

7a = 14.5 - 0.5

7a = 14 Divide by 7

a = 14/7

a = 2
