Line with slope m through (a,b) is

y - b = m(x - a)

(1,-1) slope 5

y + 1 = 5(x - 1)

y = 5x - 6

answer: 39d

(4,5) slope 3

y - 5 = 3(x - 4)

y = 3x - 7

answer: 40d

A triangle ABC is inscribed in the circle, (ABC = 65° and AB=AC. Find (BDC.

podryga [215]

Answer:

∠BDC=50°

Step-by-step explanation:

∠BDC=∠A[angles at the same segment)

∠A= 180-(65+65)=180-130= 50°

so, ∠BDC=50°

Solve for f -f +2 + 4f = 8 - 3f

Ulleksa [173]

Answer:

f=1

Step-by-step explanation:

Let start off with doing -f plus 4f which gives you 3f. The equation would now be 2+3f=8-3f. Add 3f so you can cancel out the -3f and add the 3f to the other 3f. Now your equation is 2+6f=8. Cancel out do by doing -2. (Don't forget to to it to the 8 also.) Now your equation is 6f=6. Divide 6 from both sides to get 1. (You divide because you want to get f alone.

I need help ASAP!!!!

mrs_skeptik [129]

Answer:

Step-by-step explanation:

the shape is made up of 2 circles and one box add the 3 areas up

circle area = $\pi$ $r^{2}$

3.14* $4^{2}$ = 50.24

50.24*2 =100.48

box, box, pit now :P ooh I was thinking formula one racing, ( i've been watching that lately) anyway

box = 8*8 = 64

total = 164.48 is that an option? hmm, yes the bottom two choices.. now the perimeter . the perimeter is made up of the 2 circles

the circumference of a circle is 2 $\pi$ r

2* $\pi$ *r

2* $\pi$ *4 =25.1327 that's one whole circle , multiplied by 2 , I can see , by math in my head that's about 50.26

sooo

the 3rd choice looks good :)

The wind is blowing N 35.0 degrees W at 1.60 * 10^2 mph. A plane has an engine speed of 3.20 * 10^2 mph. Where should the pilot

Answer: 24.2° SouthWest

Step-by-step explanation:

First step: DRAW A PICTURE of the vectors from head to tail (see image)

I created a perpendicular from the resultant vector to the vertex of the given vectors so I could use Pythagorean Theorem to find the length of the perpendicular. Then I used that value to find the angle of the plane.

Perpendicular (x):

cos 35° = adjacent/hypotenuse

cos 35° = x/160

→ x = 160 cos 35°

Angle (θ):

sin θ = opposite/hypotenuse

sin θ = x/320

sin θ = 160 cos 35°/320

θ = arcsin (160 cos 35°/320)

θ = 24.2°

Direction is down (south) and left (west)
