Explanation:
Since sin
θ
is negative, it can be in the third or fourth quadrant
Drawing your right-angled triangle, place your
θ
in one of three corners. Your longest side will be 3 and the side opposite the
θ
will be -2. Finally, using Pythagoras theorem, your last side should be
√
5
Now, if your triangle was in the third quadrant, you would have
cos
θ
=
√
5
−
3
since cosine is negative in the third quadrant
But if your triangle was in the fourth quadrant, you would have
cos
θ
=
√
5
3
since cosine is positive in the fourth quadrant
Answer:
525
Step-by-step explanation:
multiply 1250 by the decimal form of the percentage (42% turns to .42)
Answer:
$64188.26
Step-by-step explanation:
→ Calculate the increase in decimal multiplier
( 100 + 3 ) ÷ 100 = 1.03
→ Multiply this by the salary raised to the power of 16
40000 × ( 1.03 )¹⁶
→ Solve
$64188.26
The coordinate of point D that divides segment MJ in the ratio 7/16 is (13, 8)
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let us assume that point M is at (20, 1) and point J is at (4, 17), hence:
If point D(x, y) is 7/16 M to J, then:
x = (7/16)(4 - 20) + 20 = 13
y = (7/16)(17 - 1) + 1 = 8
The coordinate of point D that divides segment MJ in the ratio 7/16 is (13, 8)
