M= (7-1)/(2-0)=3
y=3x + c
plug in Q
1= 3 x 0 +c
=> c =-2
=> the equation represents line QR is y=3x -2
Convert degrees to radians, multiply by π/180° , since a full circle is 360 ° 360 or 2π radians.
− 405°⋅ π /180° radians
Cancel the common factor of 45 .
-9 ⋅ π/4 radians
Combine −9 and π/4
-9π/4
Move the negative in front of the fraction.
-9π/4 radians
A_{n+1}b_{n+1} / a_{n}b_{n} =( a_{n+1} / a_{n}) * ( b_{n+1} / b_{n} ) = ( r1 ) * ( r2) =>
{a_{n}b_{n}} a geometric sequence; the common ratio is ( r1 ) * ( r2) .
Answer:
3 seconds
Step-by-step explanation:
Maximum height=150
150=-16t^2+96t+6
-16t^2+96t-144=0
-16(t^2-6t+9)=0
-16(t-3)^2=0
t=3 seconds
M(<Q) = 90; m(<P) = 12; m(<x) = 180 - 90 - 12 => m(<x) = 78. a.
