For circle O, mCD=125° and m

Mathematics

Burka [1]3 years ago

CA is a diameter of the circle, so m\widehat{AC}=180^\circ, which means m\angle AOB=m\angle AOD=m\widehat{AD}=180^\circ-m\widehat{CD}=55^\circ. Then m\boxed{\angle ABO}=90^\circ-55^\circ=35^\circ.

This means m\angle CBO=55^\circ-35^\circ=20^\circ. Also, if m\angle AOB=55^\circ, then m\angle BOC=180^\circ-55^\circ=125^\circ, which in turns tells us that m\boxed{\angle BCO}=180^\circ-20^\circ-125^\circ=35^\circ.

a line is perpendicular to y=-4x-2 and intersects the point (0,9). what is the equation for this perpendicular line?
AysviL [449]

Answer:

y=(1/4)x + 9      OR      y=x/4 +9

Step-by-step explanation:

Perpendicular lines have a slope/gradient of -1/n

Because the slope of this line is -4, the slope of a line perpendicular to it would be 1/4.

y=(1/4)x+b

(0,9) is the y-intercept, so b = 9

y=(1/4)x + 9      OR      y=x/4 +9

You deposit $2200 into three separate bank accounts that each pay 3% annual interest. How much interest does each account earn a
Keith_Richards [23]
This can be solve using the formula:
F = P ( 1 + i)^n
where F is the money after n years
P is the initial amount of money
i is the annual interest rate
n is the time in years
since you deposit in 3 accounts P = 2200/3
F = ( 2200 / 3) ( 1 + 0.03)^6
F = $ 875.64 is the money each account earned after 6 years

Write the equation of a line that is perpendicular to the line that passes through (4,−3)and (−7,8).
masha68 [24]

Line perpendicular to a given line is = 1/m

To find m, use m =y2-y1/x2-x1 formula

m = (8-(-3))/(-7-4)

m = 11/-11,

m = -1

Use y= mx+c to find equation of line

Plug in a pair of values,

-3= -1(4)+ c

c= 1

Thus, equation is:

y = -x+1

Equation of line perpendicular to this line is:

y= x+1

Hope it helps :)
