let f(x)=4x-5. describe the transformation from the graph of f to the graphs s(x)= -f(x) and t(x)= f (-x)
KengaRu [80]

Answer:

Answer:

g(x)=-6/5x+1/2

h(x)=-6/5x-1/2

Step-by-step explanation:

1).   g(x)=−f(x) ?

f(x)=6/5x−1/2

g(x)=−(6/5x−1/2)

g(x)=-6/5x+1/2

2). h(x)=f(−x) ?

f(-x)=6/5(-x)−1/2

f(-x)=-6/5x-1/2

h(x)=-6/5x-1/2

Angles formed by transversals: I need the answer to this question ASAP please help me out. Thank You.
Anna [14]

Answer:

148, 32, 32

148, 148, 323

32, 148

Step-by-step explanation:

m<1 = m<4 = m<5 = m< 8 = 180 - 32 = 148 degrees

m<2= m<3 = m<6 = m<7 = 32 degrees

7x+18 = 2x+28

5x = 10

x=2

2*2 +28 = 32

A spherical shell has inner radius r and an outer radius r+h. Let h=0.1r. Find the volume of the shell in terms of r and then ap
umka21 [38]

Step-by-step explanation:

The volume of the shell is the volume of the outer sphere minus the volume of the inner sphere.

V = 4/3 π (r+h)³ − 4/3 π r³

V = 4/3 π (r³ + 3r²h + 3rh² + h³) − 4/3 π r³

V = 4/3 π r³ + 4π r²h + 4π rh² + 4/3 π h³ − 4/3 π r³

V = 4π r²h + 4π rh² + 4/3 π h³

If h = 0.1 r:

V = 4π r² (0.1 r) + 4π r (0.1 r)² + 4/3 π (0.1 r)³

V = 0.4π r³ + 0.04π r³ + 0.00133π r³

V = 0.44133π r³

Using the approximation:

V = 4π r² h

V = 4π r² (0.1 r)

V = 0.4π r³

The approximation is reasonable if h is small compared to r.
