Answer:
4r - 10s OR 4r + (-10s)
Step-by-step explanation:
There are no like terms so I can't do anything so the answer remains as 4r - 10s... UNLESS U WANT TO KEEP CHANGE CHANGE AND THEN YOUR FINAL ANSWER WILL BE 4r + (-10s)
p(x) × q(x)
= (3x² - x + 1) × (2x² + 3x - 2)
= 6x⁴ + 9x³ - 6x² - 2x³ - 3x² + 2x + 2x² + 3x - 2
= 6x⁴ + 7x³ - 7x² + 5x - 2
A right angle is an angle at 90 degrees
Answer:
two hundred nineteen and 44
OR
two hundred nineteen point 44
Step-by-step explanation:
do not say AND before nineteen. saying AND represents a decimal point. Both can be used (point or and)
Answer:
e)
f)
g)
h)
i)
j)
Step-by-step explanation:
We can solve this exercise by watching a basic trigonometric table
Here i will list values of sin and cos in the points and
Hence, the sin takes the value 1 on , while it takes the value -1 in its opposite value - \pi/2 (because it is an odd function). If we use the periodicity of the sin, then sin(- \pi/2 + 2 \pi) = -1. Hence
The cos takes value 1 in 0, and it takes the value -1 in
The tangent is the quotient between sin and cos. The tangent is 1 when both cos and sin are equal. We can see that they are equal in , where they take the value
The tangent is -1 where they are the opposite. This happens in where they take the value and respectively.
