Answer:

Step-by-step explanation:

$\textsf {Given :}$

$\mathsf {x - 5 \leq -13}$

$\textsf {Add 5 to each side of the inequality : }$

$\mathsf {x - 5 + 5 \leq -13 + 5}$

$\mathsf {x \leq -8}$

1/√2

Step-by-step explanation:

Imagine a right-angled triangle, for e.g. Triangle ABC,

Where

B = 90°

Remember your Toa Cah Soh.

sin 45° = opposite / hypotenuse

If theta = 45°

Angles A and C = 45° (Sum of angles in a triangle equal = 180°)

Since theta are the same, we can also deduce that the length AB and BC are the same.

Take for example AB = BC = 1 = opposite

By the Pythagorean theorem,

AB² + BC² = AC²

1² + 1² = AC²

2 = AC²

AC = √2 = hypotenuse

Therefore:

sin 45° = opposite / hypotenuse

sin 45° = 1/√2

If 10^2y = 25, then 10^-y equals: (a) -1/5 (b) 1/625 (c) 1/50 (d) 1/25 (e) 1/5

Gemiola [76]

<h3>given:</h3>

$10 ^{2y} = 25$

${10}^{y} = .......$

<h3>solution:</h3>

$10 ^{2y} = 25$

$(10y {)}^{2} = {5}^{2}$

$10y = 5$

$\frac{1}{ {10}^{y} } = \frac{1}{5}$

${10}^{ - y} = \frac{1}{5}$

therefore, the correct answer is option E.
