Step-by-step explanation:
By Sine Rule, 13/sin96° = x/sin25°.
Hence, x = 13sin25°/sin96° = 5.5.
A polynomial with a degree of 3 is understood to have three zeroes or roots. In the given problem in 1, x3 + 6 x2 – 9x – 54, the roots of the polynomial using the calculator are B. B. 3, -3, -6. The same applies for number 2 given the polynomial x3 – 4x2 + 3x – 12. The answer in 2 is D. 4 years. The roots of the polynomial in 3 are:
<span>x1=−0.45117</span>
<span><span>x2</span>=1.77474</span>
<span><span>x3</span>=0.03821+0.70576∗i</span>
<span><span><span>x4</span>=0.03821−0.70576∗i. Hence there is A. 1 negative root.</span></span>
<u>Answer:</u>

<u>Step-by-step explanation:</u>
We are to find the equation for the line which is perpendicular to another line with the equation
and passes through a point (2, 10).
Since the slope of a line which is perpendicular to another line is the negative reciprocal of the other line, therefore the slope of our line will be
.
Finding the y-intercept:



Therefore, the equation of the line will be
.
X is a placeholder,
if 1x = 6
then 7x = 1x * 7 and because we know 1x = 6 then it is
7 * 6 = 42
