Answer:
x⁵ + 5x³ + 7x² + 35
Step-by-step explanation:
(x² + 5) (x³ + 7)
To distribute binomials (expressions with two terms), you can use the FOIL method (First, Outer, Inner, Last):
x⁵ + 7x² + 5x³ + 35
To put into standard form, rearrange from highest power to lowest power:
x⁵ + 5x³ + 7x² + 35

Answer:
16°
Step-by-step explanation:
2x° + 6° = 38°
x° = (38°- 6°)÷2=16°
Answer:
Your answer is B
Step-by-step explanation:
The lowest number is 4, therefore it cannot be C.
Now you'll have to cross out numbers on both sides and your mean will be 9 because you'll have to add 8 and 10 together and 18 divided by 2 is 9.
Next, put a line between 8 and 10, now the 8 side is the lower quartile and the 10 side is the greater quartile.
For the lower quartile, add 7 and 7 together, divide 14 by 2 and the lower quartile is 7.
For the greater quartile, add 11 and 13 together, that's 24, divide 24 by 2 and that's 12.
Lowest: 4
Mean: 9
Lower quartile: 7
Greater quartile: 12
Highest: 14
Therefore your answer is B and not A or C.
Question:
If cos(θ) =-8/17 and sin(θ) is negative, then sin(θ) = ___ and tan(θ) =___.
Answer:
Step-by-step explanation:
Given
cos(θ) =-8/17
Required
sin(θ) = __
tan(θ) =__
The first step is to determine the length of the third side
Given that
Where Adj and Hyp represent Adjacent and Hypotenuse
By comparison
Using Pythagoras
By Substitution
Subtract 64 from both sides
Take square roots of both sides
The question says that sin(θ) is negative; This implies that θ is in the third quadrant and as such
From trigonometry
Also from trigonometry
