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.

If m = 5 and n = -2, evaluate 3m - 4n and n2 - m and find the product of the two expressions.
ddd [48]

Hence the correct answer is C) -23

Further explanation:

We have to put the values of m and n into both expression first separately and then multiply the answers.

Given expressions are:

Exp\ 1:3m-4n\\Exp\ 2: n^2-m

The values are:

m=5\\n=-2

Putting the values in expression 1:

3m-4n\\=3(5)-4(-2)\\=15+8\\=23

Putting the values of m and n in second expression

n^2-m\\=(-2)^2-5\\=4-5\\=-1

Multiplying both expressions:

(3m-4n)(n^2-m)=23* (-1)=-23

Hence the correct answer is C) -23
