Calculate the value of x.

Answer:

49.2°

Step-by-step explanation:

To solve for x you'll need to find the cosine of x°.

To find the cosine you will need to divide the adjacent side to it by the hypotenuse.

cos x°= \frac{17}{26}

Using a calculator to solve you'll get that x ≈ 49.2°

Calculate S5 for the sequence defined by {an}={1+5/2n}<br><br> 13.5<br> 23<br> 40<br> 42.5
goldfiish [28.3K]
This is an arithmetic series, where S5 means the sum of the first 5 numbers in the series. The general formula is:

Sn = (n/2)(a1 + an)

So,
a1 = 1 + 5/2(1) = 3.5
a5 = 1 + 5/2(5) = 1.5

S5 = (5/2)(3.5+1.5)
S5 = 12.5

<em>The answer should be 12.5</em>

Techwiz electronics makes a profit of $35 for each MP3 player sold and $18 for each DVD player sold. Last week, Techwiz sold a c
kicyunya [14]

The combined total profit is (17x + 2502) dollars

<em><u>Solution:</u></em>

Profit for each Mp3 player = $ 35

Profit for each DVD player = $ 18

Let x be the number of MP3 players sold last week

Number of MP3 players = x

Last week, Techwiz sold a combined total of 139 MPS and DVD players

Total number of mp3 and dvd sold = 139

Number of DVD player = 139 - x

<em><u>Write an expression for the combined total profit (in dollars) Techwiz made from MP3 and DVD players last week.</u></em>

Combined total profit = Number of MP3 players x Profit for each Mp3 player + Number of DVD player x Profit for each DVD player

combined\ total\ profit = x \times 35 + (139-x) \times 18\\\\combined\ total\ profit = 35x + 2502-18x\\\\combined\ total\ profit = 17x + 2502

Thus the combined total profit is (17x + 2502) dollars
