That is, if you are referring to Newton’s 2nd Law.
Answer: x > 8
Step-by-step explanation: To solve the inequality x - 7 > 1, our goal is the same as it would be if we were solving an equation, to get <em>x</em> by itself on one side.
So here, since 7 is being subtracted from <em>x</em>, we need to add 7 to both sides of the inequality to get x > 8. We then write our answer in <em>set notation</em>, as the set of all x’s such that x > 8, shown below.
<h2>{x : x > 8}</h2>
It's important to understand that this solution set means that any number greater than 8 is a solution to this inequality.
For example, 9, 10, 28, 872, 642,000, and so on
are all solutions to this inequality.

Answer:
45
Step-by-step explanation:
year 1 : 18 in
every year after that he grows 3 in so 3 in so 3x9=27
then 27+18=45
Answer:
<h2>cos 60° = 1/2 because the angles are complements</h2>
Step-by-step explanation:
Given sin 30° = 1/2, to check which of the statements is correct we will apply the Pythagoras theorem to a right angled triangle shown in the attachment.
using the SOH CAH TOA trig identity on the right angled triangle, ACD gotten from the equilateral triangle ABC;
From ΔACD, AD is the hypotenuse, DC is the opposite side to the angle 30° and AC is the adjacent.
From the diagram, sin30° = opp/hyp = DC/AD
sin30° = 1/2
Taking consideration of the acute angle 60°, the opposite side to the angle will be AC and the adjacent side will be CD.
According to CAH, cos 60° = adj/hyp = CD/AD
Given CD = 1 and AD = 2
cos60° = 1/2
This shows that sin30° = cos60° = 1/2
Note that ∠CDA and ∠DAC are angles complementary. Complementary angles are angles which have its sum to be 90°
