Is y=arcsec(1) equivalent to 0? Thanks!

1 answer:

3 0

arcsin(1) = 90 degrees
arccos(1) = 0
arctan(1) = 45 degrees

When you say "arcsec(1)", do you mean the angle whose secant is 1 ?

Since the secant is 1/cosine, if the secant of your angle is 1, then
its cosine is also 1, and the angle is zero (and 360).

Can someone plz help me with circle theorems.

AOD = 180 - (90+32) = 58 because when a tangent meets a radius they form a right angle

ABC = 1/2 AOD = 29 because it's subtended by the same ark as the AOD and O is center of the circle

Miguel has a total of 27 dimes and nickels. The total value of the coins is $1.80. How many dimes and nickels does he have?

soldi70 [24.7K]

Answer:

There are 9 dimes and 18 nickels.

Step-by-step explanation:

Let d = be the number of dimes

n = be the number of nickels

d + n = 27...eq.1

0.10d + 0.05n = 1.80...eq.2

Solve the system of equations

d + n = 27

10d + 5n = 180 ( multiply eq.2 by 100 )

-5d - 5n = -135

5d = 45

d = 9 , there are 9 dimes so,0.90

n = 27 - 9 = 18, there are 18 nickels so, 0.90

To check: 9 dimes + 18 nickels = 27 coins

0.90 + 0.90 = $ 1.80 total value of the coins
