If I understand your sequence, then this is the "closed form" of the sequence:

a_n = 63 - 4 n

Sum = (59, 55, 51, 47, 43, 39, 35, 31, 27, 23, 19, 15, 11, 7, 3) = 465

Given f(x) = 5x^6 what is the domain?5 < X ≤ 6x ≥ 0X ≤ Oall real numbers

Vilka [71]

The domain is the set of all possible x-values which will make the function "work", and will output real y-values

$\begin{gathered} \text{Let} \\ f(x)=5x^6 \\ \end{gathered}$

there is not a value for x, that makes the function does not "work", so x can take any value, in other words all real numbers

so, the answer is all real numbers

A baseball player bunts a ball down the first base line. It rolls 32 ft at an angle of 25degrees with the first base path. The

Furkat [3]

Answer:

32.3 feet

Step-by-step explanation:

Let BC=32 feet

AC=60.5 feet

The angle between side BC and AC=45-25=20 degrees

We have to find the distance traveled by player to get to the ball.

Cosine law: $c^2=a^2+b^2-2ab Cos\theta$

Using Cosine law

$c=\sqrt{(32)^2+(60.5)^2-2(32)(60.5)Cos 20^{\circ}}$

$c=\sqrt{(32)^2+(60.5)^2-2(32)(60.5)(0.9396)}$

$c=32.3 feet$

Hence, he travel 32.3 feet to get to the ball.
