Answer:
b) (-3 + 5i)(1) = -3 + 5i
Step-by-step explanation:
First let's see what a multiplicative identity.
The <em>multiplicative identity property </em>states that any time you multiply a number by 1, the result is the original number.
Therefore, 1 is the multiplicative identity.
For instance, 3 * 1 = 3
Hence, according the property
(-3 + 5t)(1) = -3 + 5i states the multiplicative identity.
Hope you will understand the concept.
Thank you.
Answer:
|x| > 1
Step-by-step explanation:
The absolute value inequality
|X| > k
where X is an expression in x and k is a non-negative number is solved by solving the equivalent compound inequality
X < -k or X > k
Here you are working backwards. You know you want the compound inequality to be
x < - 1 or x > 1,
so using the variable expression x for the expression X and 1 for k, write the absolute value equation
|x| > 1
Answer:
14.6 = x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hyp
sin 66 = x/16
16 sin 66 = x
14.61672732 =x
To the nearest tenth
14.6 = x
Answer:
$231.42
Step-by-step explanation:
Find the tub radius. It is C = 2πr, which here is C = 6.28(5.5 ft ) = 34.54 ft.
The border costs $6.70/ft. Multiply $6.70/ft by 34.54 ft:
($6.70/ft)(34.54 ft) = $231.42
