PLEASE! ANSWER THIS! HELP! PLEASE!!!!!!!!!!!!!! <br><br>c. Expand: (tan(theta) - 1)^3​
jonny [76]

Answer:

(tan(theta)-1)^3

= (tan(theta)-1)(tan(theta)-1)(tan(theta)-1)

= (tan^2(theta)-2tan(theta)+1)(tan(theta)-1)

= tan^3(theta)-2tan^2(theta)+tan(theta)-tan^2(theta)+2tan(theta)-1

= tan^3(theta)-3tan^2(theta)+3tan(theta)-1

Hope this helps :)

Describe how to evaluate the expression 3^2 + (21 - 9) X 6÷2. Can someone help me out, please? I'm having trouble, and my teache
mylen [45]

Answer:

3^2+\left(21-9\right)\times \:6\div \:2=45

Step-by-step explanation:

Given the expression

3^2\:+\:\left(21\:-\:9\right)\:\times \:6\div 2

Follow the PEMDAS order of operations

3^2\:+\:\left(21\:-\:9\right)\:\times \:6\div 2

calculate within parentheses  \:(21-9)=12

=3^2+12\times \:6\div \:2

calculate exponents  3^2=9

=9+12\times \:6\div \:2

Multiply and divide (left to right)

=9+36

Add and subtract (left to right)  12\times \:\:6\div \:\:2=36

=45

Thus,

3^2+\left(21-9\right)\times \:6\div \:2=45

If the points (-3,2),(4,-4) are joined to form a straight line, at what point does the line intersect the y-axis
Mashcka [7]
Construct the line using the two points:
slope: m = (-4 - 2) / (4 + 3) = -6/7;
then, y = mx + b => 2 = (-6/7)(-3) + b => 14/7 - 18/7 = b => b = -4/7.
And your y-intersect is -4/7.
