Answer:

f(2a−1)=7a−13

7(2a−1) − 13

14a − 7 − 13

14a − 20

Step-by-step explanation:

replace a with f(2a − 1)

distribute the bracket

combine -7 and -13 because they are the like terms here.

Find the altitude of the triangle.<br> 30 degrees<br> Hypotenuse of 14

Oxana [17]

Answer:

Approx. 12.124 units tall

Step-by-step explanation:

Since you need to find the height (which is adjacent to the given angle), you need to use cosine (adj. over hypotenuse).

cos(30) = x/14

Multiply both sides by 14:

14cos(30) = x

Hope this helps :)

If 4 (log3 1/27)=X what is the value of X

givi [52]

$4(log _{3} 1/27) =x$
$log _{3} \frac{1}{27}^4 =x$

Now remember: $b^y=x \\ equals \\ log _{b}x=y$

$3^x = \frac{1}{27}^4$
$3^x = \frac{1}{531441}$
$log _{3} \frac{1}{531441} =x$
$\frac{ln\frac{1}{531441}}{ln3} = x$
$\frac{1}{531441} = 0.000002$
you can now enter this into your calculator...

Answer: x = -0.083

One fourth dived by one fourth

viva [34]

1; (1/4)/(1/4), all you do is flip the fraction to make the reciprocal and multiply, so (4/1)x(1/4)=1
