Answer:

parallel line: y=-3x+14

perpendicular line: y=1/3x +2/3

Step-by-step explanation:

For the parallel line, use the point-slope formula to find the equation of the parallel line (since the slope is the same as the given line and the point (4,2) is given. For the perpendicular line, use the opposite reciprocal of the slope of the given line and use the point-slope formula again. The point-slope formula is Y-Y1=m(X-X1)

A car's rear windshield wiper rotates 130°. The total length of the wiper mechanism is 25 inches and the length of the wiper bla
Delicious77 [7]

The area wiped by the viper blade is approximately 486.7 square inches.

The area wiped by the wiper blade (A), in square inches, is equal to the area of the circular section described below:

A = \frac{\theta\cdot \pi}{360}\cdot (R^{2}-r^{2}) (1)

Where:

  • \theta - Angle, in sexagesimal degrees.
  • r - Inner radius, in inches.
  • R - Outer radius, in inches.

If we know that \theta = 130^{\circ}, R = 25\,in and r = 14\,in, then the area wiped by the wiper blade is:

A = \frac{130\pi}{360} \cdot [(25\,in)^{2}-(14\,in)^{2}]

A \approx 486.7\,in^{2}

The area wiped by the viper blade is approximately 486.7 square inches.

What is the relationship between fractions and decimals?
Tanzania [10]
The relationship between fractions and decimals is that with a fraction you are dividing whereas a decimal is treated like a number.
i.e.      1/4=0.25
Think of decimals as 100 being the whole or 1 so split 100 into 4 and you get 25 or 0.25

Why is the lcm of two numbers never less than the larger number?
Lady bird [3.3K]
This involves a bit of logic in thinking about what LCM actually means.

LCM is the least common multiple. A common multiple is a multiple shared by two or more numbers. And by multiple, we mean some number multiplied by successive integers; this set contains multiples of 5 {5, 10, 15, 20, 25...}. You can see that the least (or lowest) common multiple is the lowest multiple shared by two numbers. Like for 6 and 9, you have {6, 12, 18, 24...} and {9, 18...}, so LCM(6,9) = 18. 

Now, if an LCM must be shared by both numbers, and to get a multiple of the largest number, you have to multiply by an integer greater than or equal to 1, then the LCM of two numbers can never be less than the larger of the twi numbers. Generally, if x and y are positive real numbers, and x is greater than y, LCM(x,y)  \leq x.
