Answer:

1) intersection of both lines is the solution: (-3, 1)

2) y = -1/6x + 1 will produce a perpendicular line and intersect at only one point (slopes of 6 and -1/6 are opposite and reciprocal, thereby producing perpendicular lines)

3) 'b' can be any value except 1

Make a substitution to express the integrand as a rational function and then evaluate the integral. (Use C for the constant of i

saw5 [17]

Answer:

$I = - 7 \cdot \ln|e^{x}+7| + 9 \cdot \ln|e^{x}+9| + C$

Step-by-step explanation:

Let consider the following algebraical substitution:

$u = e^{x}$

$du = e^{x} dx$

The integral is re-arranged to this form:

$I = 2 \cdot \int\ {\frac{u\ du}{u^{2}+16\cdot u + 63} } \, dx$

After doing some algebraical manipulation, the rational form of this integral is:

$I = -\int {\frac{7}{u + 7} } \, dx + \int {\frac{9}{u + 9} } \, dx \\$

The solution of this integral is:

$I = - 7 \cdot \ln|u+7| + 9 \cdot \ln|u+9| + C$

$I = - 7 \cdot \ln|e^{x}+7| + 9 \cdot \ln|e^{x}+9| + C$

Billy goes on the teacup ride at the local carnival. He is seated 16 inches from the center of his teacup, which is spinning at

Orlov [11]

Answer:

Billy’s angular velocity, is 1508.16 radians per second

Step-by-step explanation:

We have to find angular velocity in radians per second

we have given angular velocity w = 4 revolutions per minute

we have to convert revolutions into radians and minutes into seconds.

so, we use the following conversion:

1 rev = 2* pi radians (where pi = 22/7 or 3.142)

1 min = 60 sec

putting the values in our equation : w = 4 revolutions per minute

=> w= 4 * ( 2* 3.142) *60

=> w= 1508.16 radians per second

hence Billy’s angular velocity, is 1508.16 radians per second
