Sedbober [7]

Answer: y - 9 = 2(x - 5)

Point slope form: y - y1 = m(x - x1)

substitute 5 for x1 and 9 for y1 and 2 for m

x1 = 5

y1 = 9

m = 2

you get y - 9 = 2(x - 5)

Find the missing side or angle.
bonufazy [111]

Answer:

c = 6.1

Step-by-step explanation:

Given that: B = 18° , C = 152°,  and b = 4.

The missing side, c, can be determined by applying the sine rule which states that:

\frac{b}{Sin B} = \frac{c}{Sin C}

\frac{4}{Sin 18^{o} } = \frac{c}{Sin 152^{o} }

c = \frac{4* Sin 152^{o} }{Sin 18^{o} }

 = \frac{1.8779}{0.3090}

 = 6.0773

c = 6.1

Therefore,  the value of the missing side, c, is 6.1

DanielleElmas [232]

Answer:

d

Step-by-step explanation:

Volume can be described as the total amount of space that is in a closed surface. this amount of space is usually three dimensional. Volume is usually measured in m³ or cm³ or in³

For example,  the volume of a rectangular box given the following dimension : length - 3cm

breadth - 8cm

height - 10 cm

volume = length x width x height = 8 x 3 x 10 = 240 cm³

Solve for h, if the given equation is: s=2πr^2+2πrh solve
dolphi86 [110]
First isolate the group with h in it
minus 2pir^2 from both sides
s-2pir^2=2pirh
divide both sides by 2pir
(s-2pir^2)/(2pir)=h

Helpppppppppppppppppppppppppppppppppppp
Vadim26 [7]

Answer:

m = - 1

Step-by-step explanation:

9m + 13 = 4

subtract 13 from both sides

9m = 4 - 13

9m = - 9

divide both sides by 9

m = - 1  (negative 1)
