We are asked to find the principal value of
cos ⁻¹ (0.69)
which is just the least positive angle
cos ⁻¹ (0.69) = 46.37°
Other values of 
cos ⁻¹ (0.69) is
46.37° - 180° n

levacccp [35]

Answer:

Option A , (0, 20); y equals one over eighty times x squared plus 20

Step-by-step explanation:

 

The equation of parabola is given by  

(X-h)^2 = 4p(Y-k)^2

In this case h = 0  

So we get  

Y = X^2/4P +k

Focus point is (h, p+k) , p+k = 40  

Hence h, k = (0,20)

P = 40-k = 20

Equation Y = X^2/80 +20  

Hence, option A is correct

Multiply: (-5qr) × (-2pqr) × pq​
ahrayia [7]

Answer:

The product of (-5·q·r) × (-2·p·q·r) × p·q is 10·q³·r²·p²

Step-by-step explanation:

The question relates to the rules of multiplication of variables and indices rules, and simplifification of an expression ;

The given expression is (-5·q·r) × (-2·p·q·r) × p·q

Therefore, we have;

(-5·q·r) × (-2·p·q·r) × p·q = (-5) × (-2) × q×q×q × r×r ×p×p = 10 × q³ × r² × p²

10 × q³ × r² × p² = 10·q³·r²·p²

∴ (-5·q·r) × (-2·p·q·r) × p·q = 10 × q³ × r² × p² = 10·q³·r²·p²

(-5·q·r) × (-2·p·q·r) × p·q = 10·q³·r²·p².
