Are the linear equations in standard form? sort each equation into the appropriate category.

1 answer:

4 0

What equation? You would have to pass a photo, but...
Standard form is: ax+by=c
Slope intercept form is: y=my+b
Point slope for is: y − y1 = m(x − x1)

Log base 2 (1/4) ...?

liubo4ka [24]

Log ( base 2 ) ( 1 / 4 ) =
= log ( base 2 ) ( 2 ^(-2 ) ) =
= - 2 log ( base 2 ) 2 = ( because : log x^n = n log x )
= ( - 2 ) * 1 = ( because: log (base x) x = 1 )
= - 2

What Is the slope of the line on the graph?

lara31 [8.8K]

Answer:

1/2 or 0.5

Step-by-step explanation:

m=y2-y1/x2-x1

I'll use the points (2,3) and (4,4) on the line

4-3=1

4-2=2

1/2=1/2 or 0.5

A guidebook says this tower is 50m tall.Is that correct? given deegrees are 27° and 46°<br>

inysia [295]

Answer:

yes

Step-by-step explanation:

The tower is about 50.1 meters tall. The guidebook is correct.

The distance from the base of the tower to the angle vertex is ...

d1 = h/tan(46°)

d2 = d1 +50 = h/tan(27°)

Then the height of the tower is ...

h/tan(46°) +50 = h/tan(27°)

50 = h(cot(27°) - cot(46°))

h = 50/(cot(27°) -cot(46°)) ≈ 50/(1.96261 -0.96569) ≈ 50/0.99692

h ≈ 50.1544 . . . meters

The tower is more than 50 meters high.
