Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in right triangle BPO
with PB = 4 ( half of AB ) and OB = 5 ( radius of circle )
OP² + 4² = 5²
OP² + 16 = 25 ( subtract 16 from both sides )
OP² = 9 ( take the square root of both sides )
OP = = 3
You'd do the same as in
brainly.com/question/2700999lemme hmmm redo the fractions... and as I said, you flip them around as needed
notice, we flipped them some, so the unit ends either above or below
in order to cancel the one on the left
Answer:
Answer is 70 degree
Option b. 70 degree
Step-by-step explanation:
please mark as brainliest.
Angle QPR= 90 degree
Therfore, Angle QPS= 90-20
= 70 degree
Solution:
y = 2x^2 - 3 ---- equation 1
y = 3x - 1 ------equation 2
Then we get,
2x^2 - 3 = 3x - 1
Now, simplifying the equation, we get
2x^2 - 3x - 3 + 1 = 0
2x^2 - 3x - 2 = 0
After factoring the equation, we get
(2x+1)(x-2) = 0
So, this means
(2x+1) = 0 and (x-2) = 0
From this, we get
x = -1/2 and x = 2
Putting values of x = -1/2 in equation 2
y = 3(-1/2) - 1
y = -2.5
Now, putting value of x = 2 in equation 2
y = 3(2) -1
y = 5
