Find a, b , and h so that f(x)= a sin (b(x-h)) f(x)=5cosx+2sinx

1 answer:

7 0

So 527/sin(48.6) = 310/sin(x)

when you find x, that would be the angle of B. and then you can find the angle C by adding angle A and B and subtracting from 180 degrees.

then you can use the law of sines again, with angle C.

Law Incorporation [45]

H=-16t^2+56t+1, the airplane is shot up from a platform 1 foot above the ground, so 1= - 16t^2+56t+1, we solve this equation
(- 16t+56)t=0, (- 16t+56)=0 or t=o, - 16t+56=0, implies t =3.5s
so the answer is C)3.5 seconds

NEED HELP WITH THESE

faltersainse [42]

Step-by-step explanation:

1 .f(x)= $x^{2}$ -x+1

f(-1)= (-1)-(-1)+1

f(-1)= 1+1+1

= 3

3.f(x)= $x^{2}$ -x+1

f( 1)=(1)-1+1

f( 1)=1-1+1

5. f(x)= $x^{2}$ -x+1

f(3)= $(3)^{2}$ -3+1

= 9-3+1

2. g(x) = 5 - 3x

g( -8)=5-3(-8)

g( -8)=5+24

=29

4.g(x) = 5 - 3x

g(5)=5-3(5)

g(5)=5-15

=-10

6.g(x) = 5 - 3x

g(-3)=5-3(-3)

g(-3)=5+9

=14
