dalvyx [7]

Answer: 170^{\circ}

Step-by-step explanation:

Given

The dog has a 25 ft leash

Arc length is 74.3 ft

Arc length is given by

l=\dfrac{\theta }{360^{\circ}}\times 2\pi r

here, r=25 ft

l=74.3 ft

Put the values

\Rightarrow 74.3=\dfrac{\theta }{360^{\circ}}\times 2\pi \times 25\\\\\Rightarrow \theta =170.2^{\circ} \approx 170^{\circ}

The measure of the angle is  170^{\circ}

Find a cubic function that has the roots 5 and 3-2i
Zolol [24]

Answer:

P(x)=x^3-11x^2+43x-65

Step-by-step explanation:

If the complex number 3-2i is a root of a cubic function, then the complex number 3+2i is a root too. Thus, the cubic function has three known roots 5,\ 3-2i,\ 3+2i and can be written as

P(x)=(x-5)(x-(3-2i))(x-(3+2i)),\\ \\P(x)=(x-5)(x^2-x(3-2i+3+2i)+(3-2i)(3+2i)),\\ \\P(x)=(x-5)(x^2-6x+9-4i^2),\\ \\P(x)=(x-5)(x^2-6x+9+4),\\ \\P(x)=(x-5)(x^2-6x+13),\\ \\P(x)=x^3-11x^2+43x-65.

Write a function g whose graph represents a reflection in the y-axis of the graph of f(x)=|2x−1|+3
ikadub [295]

Answer:

Step-by-step explanation:

f(x) = |2x−1|+3, reflected over the y-axis becomes

g(x) = |-2x−1|+3

We needed the point (0.5, 3) to go to the other side of the y-axis to get the point (-0.5, 3).

I don’t know what to do here
Rudik [331]
The answer is CD = √3

This is because of the fact that a 30-60-90 right triangle has proportions of 1-√3-2 based on the length opposite of the angle. Since we are given the segment opposite to the right angle as 2, we know that we can use the base numbers for the proportions to find the rest. Since CD is opposite of the 60 degree angle, it must be √3.
