∵the line is ⊥ to -7x -8y =12
∴its slope = -(-7/-8)= -7/8
∵it passes through P
∴(y-1)=(-7/8)(x+3)
y-1 = (-7/8)x - 21/8
y = (-7/8)x -13/8

the diameter of your bicycle wheel is 34 inches.What is its radius?How far will you move in one turn if your wheel?What is the d
gulaghasi [49]

Answer:

Step-by-step explanation:

The radius of a circle is always half the radius.

Thus, in this case, the radius is (1/2)(34 in) = 17 in.

The "how far" question is answerable by finding the circumference of the wheel.  The circumference, C, is found by calculating C = πd, where d is the diameter of the circle in question.

Here, C = (34 in)π, which comes out to 106.81 inches.  The bike will move 106.81 inches forward if the wheel turns once.

If the wheel turns 5 times, the total distance traveled is 5 times the circumference, or 5(106.81 in) = 534.07 in.

Solve for x.<br><br> log x + log 3 = log 18<br><br> Enter your answer in the box.
Makovka662 [10]

log(x) + log(3) = log(18)

log(x) + 0.477121 = 1.255273

Add -0.477121 to both sides.

log(x) + 0.477121 + −0.477121 = 1.255273 + −0.477121

log(x)+0 = 0.778152

Divide both sides by 1.

log(x)+0/1 = 0.778152/1

log(x)=0.778152

Solve Logarithm

log(x) = 0.778152

10log(x) = 100.778152

x = 100.778152

x = 6.00001
