Mathematics
1 answer:
Klio2033 [76]3 years ago
4 0

Answer:

(2, 2/3 * pi)

Step-by-step explanation:

( -1, sqrt(3))

to find the radius

sqrt(x^2 + y^2) = r

sqrt( (-1)^2 + (sqrt3)^2) = r

sqrt(1+3) =r

sqrt(4) =r

2=r


to find theta

theta = arctan (sqrt(3)/-1)

theta = -60 degrees

you need theta between 90 and 180

add 180 to theta

theta = 120


you need theta in radians

120 * pi/180 = 2/3 * pi

Judy uses 9.7 pints of blue paint and white paint to paint her bedroom walls.3/5
Sindrei [870]

Answer:

3.88 Pints

Step-by-step explanation:

First we need to find the amount of blue paint that was used. We can do that by multiplying 9.7 by 0.60 since that is 3/5 in decimal form

9.7*0.60=5.82

Now we know how much blue paint was used, now we just need to find how much white paint was used. We can do that by subtracting our amount of blue paint from the total amount of paint used

9.7-5.82=3.88

thus, 3.88 is the amount of white paint used

Question 26: write the equation that describes the line with slope=5 and y-intercept =8 in slope intercept form.example: y=mx+b
elixir [45]

Answer:

y = 5x + 8

Step-by-step explanation:

Start with y = mx + b:  general slope-intercept form, equation of a line:

Replace m with 5, y with 8 and x with 0 (since the y-intercept is (0, 8):

8 = 5(0) + b.  Then b must be 8, and the desired equation is

y = 5x + 8
