Using the power of power rule you
{ ({a}^{x}) }^{y}  =  {a}^{x \times y}
thus
({19}^{ \frac{1}{9} } )^9 =  {19}^{ \frac{1}{9} \times 9 }  =  {19}^{1}  = 19

In right triangle DEF, it is known that Cos D = (12/13) and Cos F = (5/13). If FD = 39, then DE = ? Hint, draw the right triangl
AnnyKZ [126]

Answer:

The value of the line segment ED is 36.

Step-by-step explanation:

The hypotenuse represents the longest side in the right triangle. In this case, FD represents the hypotenuse as it is a multiple of 13. Based on the trigonometric relations described in the statements, we get the following relationships by definition of cosines:

\cos D = \frac{ED}{FD} (1)

\cos F = \frac{EF}{FD} (2)

If we know that \cos D = \frac{12}{13} and FD = 39, then the length of the line segment ED is:

ED = FD\cdot \cos D

ED = 39\cdot \left(\frac{12}{13} \right)

ED = 36

The value of the line segment ED is 36.

Is 0.7 =0.07 reasonable? explain why if its not or it is
MrRissso [65]

Answer:

No

Step-by-step explanation:

No, because 0.7 is greater than 0.07 {Tip: Look for place of the decimal}

0.7 is written as 7/10 and 0.07 is written as 7/100

0.7 which is 7/10 is also written as 70/100 Hence, it clearly that 70/100 is greater than 7/100

0.7 is greater than 0.07 because to compare between two decimal numbers, you should look at the number after the decimal point and 7 is greater than 0 in the tenth place.

Solve for x 4x+ 14=6x-8
Tomtit [17]

x=11
x is equal to 11 because you subtract 4x from both sides and then add 8 to both sides where you are left with 2x=22. After dividing by 2, you get x=11
