Answer:
d) 86.2 degrees
x = 86.20°
Attached is the image used in the question;
Step-by-step explanation:
Applying the law of cosine;
Cos C = (a² + b² - c²)/2ab
Where;
Angle C = x
c = 13 ft
b = 9ft
a = 10ft
Substituting into the equation;
Cos x = (10² + 9² - 13²)/(2×10×9)
Cos x = 0.0667
x = cos⁻¹(0.0667)
x = 86.20°
Given that the function is f(x)=3x-2, then the value of f(0) will be given by:
f(0)=3(0)-2
simplifying the above we get:
f(0)=0-2
f(0)=-2
the answer is f(0)=-2, in other words, when x=0, then y=-2

Answer:
4
Step-by-step explanation:
The function is 4x.
For every pound you have, you will have 4 times that amount in total cost. This is because of the pattern being shown. Example: 3 × 4 = 12 6 × 4 = 24 9 × 4 = 36.. and it just goes on and on.
