When is the absolute value of a difference equal to the difference of the absolute values?

marshall27 [118]

<span>ax(d) = absolute value of the difference = ax(a-b).
d(ax) = difference of the absolute value = ax(a) - ax(b).
ax(a-b) = absolute value of (a - b).
ax(a) - ax(b) = absolute value of (a) minus absolute value of (b).

Hope this works :)</span>

In ΔSTU, the measure of ∠U=90°, the measure of ∠T=47°, and ST = 7.2 feet. Find the length of US to the nearest tenth of a foot.

Sauron [17]

Answer:

$US=5.3\ ft$

Step-by-step explanation:

we know that

In the right triangle STU

The sine of angle T is equal to the opposite side angle T divided by the hypotenuse

$sin(T)=\frac{US}{ST}$

substitute the values

$sin(47\°)=\frac{US}{7.2}$

$US=(7.2)sin(47\°)=5.3\ ft$

Find all values of c such that the domain of the following function is the set of all real numbers

Semenov [28]

Answer:

$-\sqrt{14} < c < \sqrt{14}$

Step-by-step explanation:

For the function to have a domain of all reals, the denominator cannot have a value of zero. x^2 + 2cx + 14 will not have zero as a root if it has no real solutions. A quadratic equation has no solutions when the discriminant is negative.

b^2 - 4ac < 0

(2c)^2 - 4(1)(14) < 0

4c^2 - 56 < 0

4c^2 < 56

c^2 < 14

$-\sqrt{14} < c < \sqrt{14}$
