Ava is in a hot air balloon that has just taken off and is floating above its launching point. Mary is standing on the ground 4

7nadin3 [17]

Answer:

Ava's altitude is 3 meters.

Step-by-step explanation:

The position of Ava and Mary can be described by the sides of a right angled triangle. Let Ava's altitude be represented by x.

So that applying the Pythagoras theorem, we have;

$/hyp/^{2}$ = $/Adj 1/^{2}$ + $/Adj 2/^{2}$

$5^{2}$ = $4^{2}$ + $x^{2}$

25 = 16 + $x^{2}$

$x^{2}$ = 25 - 16

= 9

x = $\sqrt{9}$

= 3

x = 3 meters

Thus, Ava's altitude is 3 meters.

Write the equation of a line that passes through the points (0, -2) and (4, -5). Answer MUST be in standard form: Ax + By = C.

shutvik [7]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b).

We have the points (4, -5) and (0, -2) → y-intercept → b = -2.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute:

$m=\dfrac{-2-(-5)}{0-4}=\dfrac{-2+5}{-4}=\dfrac{3}{-4}=-\dfrac{3}{4}$

Therefore we have the equation of a line

$y=-\dfrac{3}{4}x-2$

Convert to the standard form: $Ax+By=C$

$y=-\dfrac{3}{4}x-2\qquad\text{multiply both sides by 4}\\\\4y=-3x-8\qquad\text{add 3x to both sides}\\\\\boxed{3x+4y=-8}$
