Which equation is in slope-intercept form and represents a line with slope 0 through the point (2, 3)?

alexandr1967 [171]

I think it would be b) because you're given a slope of 0, so that leaves you with
$y=0x+b$
, resulting into this
$y=b$
You'd be just left with a continuous horizontal line going through the y-axis of 3 since you're passing the point (2,3), where 3 represents the y-value when your slope is at 0.

In the figure below, BCA ~ STR. Find cos C, sin C, and tan C. Round your answers to the nearest hundredth.

arsen [322]

Answer:

$\sin C\approx0.85\\\\\cos C \approx0.52\\\\\tan C\approx1.63$

Step-by-step explanation:

According to the trigonometric ratios in aright triangle :

$\sin x =\dfrac{\text{Side opposite to x}}{\text{Hypotenuse}}\\\\\cos x =\dfrac{\text{Side adjacent to x}}{\text{Hypotenuse}}\\\\\tan x=\dfrac{\sin x}{\cos x}$

Given: ΔBCA ~ ΔSTR

Since , corresponding angles of two similar triangles are equal.

So, ∠C = ∠T ...(i) [Middle letter]

In triangle STR

$\sin T=\dfrac{\text{Side opposite to T}}{\text{Hypotenuse}}\\\\=\dfrac{26.4}{30.9}\approx0.85\\\\\cos x =\dfrac{\text{Side adjacent to T}}{\text{Hypotenuse}}\\\\=\dfrac{16.2}{30.9}\approx0.52\\\\\tan T=\dfrac{\sin T}{\cos T}\\\\=\dfrac{0.85}{0.52}\approx1.63$ ...(ii)

From (i) and (ii), we have

$\sin C\approx0.85\\\\\cos C \approx0.52\\\\\tan C\approx1.63$

Answer:

In the given expression x:6 :: 3:9 , x = 2

Step-by-step explanation:

Here, the given expression is:

x:6 :: 3:9

or, x : 6 = 3 :9

So, by the RATIO OF PROPORTIONALITY:

$\frac{x}{6} = \frac{3}{9}\\\implies x = \frac{3}{9} \times 6 = 2$

or, x = 2

Hence, in the given expression x:6 :: 3:9 , x = 2
