(B)

Step-by-step explanation:

Look at the triangle with the 65° angle. Note that the 65° angle is opposite the 24-ft side and p is the length of the triangle's hypotenuse so let's use the definition of sine 65°:

sin 65 = opposite/hypotenuse

= (24 ft)/p

Solving for p,

p = (24 ft)/(sin 65°)

= 26.48 ft

2 and a half plus 2 and a half
Wittaler [7]

Answer:

5

Step-by-step explanation:

Using fractions:

2\frac{1}{2} = \frac{5}{2}

\frac{5}{2} + \frac{5}{2} = \frac{10}{2}

\frac{10}{2} = 5


Using decimals:

2\frac{1}{2} = 2.5

2.5 + 2.5 = 5

Which two values of x are roots of the polynomial below x^2 - 11x + 13
matrenka [14]

Because 13 is a prime number, we cannot use the AC method to simplify.

We can instead use the quadratic formula.

\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}

11 +/- √121 - 52 / 2

11 +/- √69 / 2

11 +/- 8.3 / 2

(11 + 8.3)/2 = 9.65

(11 - 8.3)/2 = 1.35

<h3>The roots of the polynomial are 9.65 and 1.35.</h3>

Eliminate the parameter of the following equations and write in rectangular form in terms of x and y.
rosijanka [135]

Solve for cos(t) and sin(t):

x = 2 + 3 cos(t)   ⇒   cos(t) = (x - 2)/3

y = 1 - sin(t)   ⇒   sin(t) = 1 - y

Recall the Pythagorean identity,

sin²(t) + cos²(t) = 1

It follows that

((x - 2)/3)² + (1 - y)² = 1

or

(x - 2)²/9 + (y - 1)² = 1
