Answer:

The equation that passes through (−7,−3)and (−2,−1) is y=2/5x-1/5

Step-by-step explanation:

m=y²-y¹/x²-x¹

m=(-1)-(-3)/(-2)-(-7)

m=2/5

y-y=m(x-x¹)

y-(-1)=2/5(x-(-2)

y+1=2/5x+4/5

-1 -1

y=2/5x-1/5

Ronch [10]

Answer:

793.25 mi/hr

Step-by-step explanation:

Given that:

The radius of the earth is = 3030 miles

The angular velocity = $\dfrac{\pi}{12} rads$

If a jet flies due west with the same angular velocity relative to the ground at the equinox;

We are to determine the How fast in miles per hour would the jet have to travel west at the 40th parallel for this to happen.

NOW;

Distance s is expressed by the relation

s = rθ

$s = 3030(\frac{\pi}{12} )$

s = 793.25

The speed which depicts how fast in miles per hour the jet would have traveled is :

$speed (v) = \frac{s}{t}$

$v = \frac{793.25}{1}$

v = 793.25 mi/hr

Hence, the jet would have traveled 793.25 mi/hr due west at the 40th parallel for this to happen.

Given: Triangles ABC and DBC are isosceles, m∠BDC = 30°, and m∠ABD = 155°. Find m∠ABC, m∠BAC, and m∠DBC.

just olya [345]

∠BDC=30, so ∠CBD + ∠BCD=180-30=150
ΔDBC is isosceles, so ∠CBD=∠BCD=half of 150=75
∠ABC=∠ABD-∠CBD=155-75=80
ΔABC is isosceles, so ∠ABC=∠ACB=80
∠BAC=180-80-80=20

* this is pretty difficult for me , provide details if necessary * // ANSWER ASAP //

fredd [130]

Answer:

Step-by-step explanation:

1 radian = 180/π

Multiplying both sides by 25π/18

We'll get,

25π/18 (r) = (180/π)×(25π/18)

= (180×25)/18

= 10×25

= 250 degrees
