Answer:
4.2 cm
Step-by-step explanation:
The law of cosines is applicable.
l² = k² +m² -2km·cos(L)
l² = 5.1² +1.2² -2·5.1·1.2·cos(35°) ≈ 17.4236
l ≈ √17.4236
l ≈ 4.2 . . . cm
It is false. Although integers above 0 divided by 0 is 0, negative numbers can also be integers (-1,-3,-10, etc.), and when they are divided by zero, they are undefined. That means that it is not really a number.
Answer:
x ≈ 1.4
Step-by-step explanation:
Using the sine ratio in the right triangle
sin50° =
=
=
( multiply both sides by 1.8 )
1.8 × sin50° = x , then
x ≈ 1.4 ( to the nearest tenth )
Answer:
a) y = 4.5
Step-by-step explanation:
y intercept is where the line crosses the y axis. so y must be 4.5
Answer:
<h2>Multiplication.</h2>
Step-by-step explanation:
The given expression is

For
, we have

Notice that the first operation we need to do is multiplication, because that's the right order of operations when we solve these kind of expressions.

Then, we subtract

Now, we divide

Finally, we sum

Therefore, the right answer is multiplication.
