Provide an appropriate response. The degree of a term that has only one variable (with a nonnegative exponent) is the exponent of that variable. The degree of a term that has more than one variable is the sum of the exponents of the variable factors. That is, the degree of 2x3y4 is 7 since the sum of the exponents (3 + 4) is 7. Given this knowledge, find the degree of the polynomial: y10 + 2xy8 - 5x4y7
A. -5 B. 11 C. 10 D. 7
Provide an appropriate response.Use the law of sines to solve the triangle ABC if a = 19, c = 15, and C = 105°. If there are two possibilities, find both solutions. Round sides to four significant digits and angles to the nearest 0.1°.
A. A = 49.7°, B = 25.3°, b = 8.406 B. A = 133.0°, B = 47.0°, b = 6.714 C. A = 133.0°, B = 47.0°, b = 6.714; A = 49.7°, B = 25.3°, b = 8.406 D. no solution
