In a 30-60-90 triangle, the length of the long leg is 8. Find the length of the hypotenuse.
fiasKO [112]

Answer:

Step-by-step explanation:

In a 30-60-90 triangle, the ratio of the lengths of the angles' opposite sides are <em>1-√3-2</em>.

If the long leg is 8, then the short one is 8/√3, or <em>8√3/3</em>.

Therefore, the hypotenuse, which is <em>double the short leg</em>, is 16√3/3.

F(t)=t^2+19t+60<br> What are the zeros of the function and what is the vertex of the parabola?
SVEN [57.7K]

Answer: -4,-15;\ \left(-\dfrac{19}{2},-\dfrac{121}{4}\right)

Step-by-step explanation:

Given

Function is F(t)=t^2+19+60

Zeroes of the function are

t^2+19t+60=0\\\\\Rightarrow t=\dfrac{-19\pm\sqrt{19^2-4\times 1\times 60}}{2\times 1}\\\\\Rightarrow t=\dfrac{-19\pm \sqrt{121}}{2}\\\\\Rightarrow t=\dfrac{-19\pm 11}{2}\\\\\Rightarrow t=-4,-15

Using completing the square method

y=t^2+2\times \dfrac{19}{2}t+\dfrac{19^2}{2^2}-\dfrac{19^2}{2^2}+60\\\\y=\left(t+\dfrac{19}{2}\right)^2+60-\dfrac{361}{4}\\\\y=\left(t+\dfrac{19}{2}\right)^2-\dfrac{121}{4}\\\\y+\dfrac{121}{4}=\left(t+\dfrac{19}{2}\right)^2\\\\\left(y-(-\dfrac{121}{4}\right)=\left(t-(-\dfrac{19}{2})\right)^2\\\\\text{The vertex is }\left(-\dfrac{19}{2},-\dfrac{121}{4}\right)

Mr. Scruggs got some money for his birthday. He spent 1/5 of it on dog treats. Then, he divided the remainder equally among his
Mariulka [41]

Answer:

a. \frac{4a}{15}

b. $225

Step-by-step explanation:

Let Mr. Scruggs got money for his birthday be 'a'

He spent \frac{1}{5} of it on dog treats = a × \frac{1}{5}

                                                                      = \frac{1}{5}a

remainder amount would be = a - \frac{1}{5}a

                                                = \frac{4a}{5}

Then he divided the remainder money equally among 3 favorite charities.

\frac{\frac{4a}{5}}{3}

= \frac{4a}{15}

a. Each charity receive \frac{4a}{15}

b. If he donated $60 to each charity.

\frac{4a}{15}=60

a=\frac{15\times 60}{4}

a = $225

Mr. Scruggs received $225 for his birthday.
