Answer:

8x + 1 + 6x + 5 = 90

14x +  6 = 90

14x = 84

x = 6

<DCB is 6x+5

6(6) + 5

36 + 5

Answer:

∠ DBC = 41°

Step-by-step explanation:

∠ DBC + ∠ DBA = 90° , substitute values

6x + 5 + 8x + 1 = 90, that is

14x + 6 = 90 ( subtract 6 from both sides )

14x = 84 ( divide both sides by 14 )

x = 6

Thus

∠ DBC = 6x + 5 = 6(6) + 5 = 36 + 5 = 41°

Which is an example x-intercept of the graph of the function y=tan(x-(5pi/6))
emmainna [20.7K]
Answer: x = 5π/6

Explanation:

1) Given function:

y=tan(x- \frac{5 \pi }{6} )

2) x-intercept are the roots of the function, i.e. the solution to y = 0

3) to find when y = 0, you can either solve the equation or look at the graph.

4) Solving the equation you get:

y = 0 ⇒ tan(x - 5π/6) = 0 ⇒ x - 5π/6 = arctan(0)

arctan(0) is the angle whose tangent is zero,so this is 0

⇒ x - 5π/6 = 0 ⇒ x = 5π/6.

Then, one example of an x-intercept is x = 5π/6, which means that when x = 5π/6, the value of the function is 0.

Since, the tangent function is a periodic function, there are infinite x-intecepts, that is why the questions asks for one example and not all the values.

You can verify by replacing the value x = 5π/6 in the given function:

y = tan (5π/6 - 5π/6) = tan(0) = 0.

Consider multiplying 26.2 by 16.43 what would a mathematician say the answer is
IgorC [24]

In mathematics multiplying decimals is just like multiplying a whole number and ignoring the decimals., then just put the decimals in the answer – it is how many decimals does the two numbers combined.

First step:

Line the numbers on the right and do not a line the decimal points

      26.2

×  16.43

Second Step:

Multiply the numbers starting on the right, just like multiplying a whole number and ignore the decimals.

       26.2

<span> ×  16.43</span>

         786

     1048

   1572

<span>+ 262   </span>

   430466

Third step: add the products

        26.2

<span> ×  16.43</span>

         786

     1048

   1572

<span>+ 262   </span>

   430.466 is the mathematician’s answer.

Randall has an account balance of $675.54 in a savings account that earns interest at a rate of 2.5% compounded twice a year. If
Alex_Xolod [135]
To calculate amount accrued after a given period of time we use the compound interest formula: A= P(1+r/100)∧n where A i the amount, P is the principal amount, r is the rate of interest and n is the interest period.
In the first part; A= $ 675.54, r= 1.25% (compounded semi-annually) and n =22 ( 11 years ),  hence, 675.54 = P( 1.0125)∧22
   = 675.54= 1.314P
 P= $ 514.109 , therefore the principal amount was $ 514 (to nearest dollar)
Part 2
principal amount (p)= $ 541, rate (r) = 1.2 % (compounded twice a year thus rate for one half will be 2.4/2) and the interest period (n)= 34 (17 years×2)
Amount= 541 (1.012)∧34
             = 541 ×1.5
             = $ 811.5
Therefore, the account balance after $ 811.5.
