Answer:
Explanation:
Identity: sec2θ=1+tan2θ
sec2(π2−x)−1=1+tan2(π2−x)−1
=tan2(π2−x)
Identity: tan(π2−θ)=cotθ
=cot2x
Answer:
Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word.
Step-by-step explanation:
Given that
1 pound of ground beef sells for $4.
To find the cost per pound:
We need to divide the cost with the number of pounds.
i.e.
If 'Number of pounds' = 1, then cost per pound = Total Cost
Therefore, the above division expression can be used to find the Cost pound.
Putting the values given to find the 'Cost per pound':
Therefore, Rosa's belief is correct that, a division expression can be used.
The correct answer is:
Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word.
X=numerator
fraction=x/16
x / 16=3/4
x=16(3/4)
x=(16*3)/4
x=12
fraction=12/16
To check:
12/16=0.75
3/4=0.75
Answer:
Step-by-step explanation:
equation of a line
y - y1 = m(x -x1)
where (x1, y1) is a point on the line and m is the slope
since it is parallel to the line 3x + y = -7, put in y = mx + b form to find the slope
y = -3x - 7, therefore m = -3
y - 1 = -3(x - 2)
Answer:
y=3(x+3)^2-8
Step-by-step explanation:
Vertex form:
y=a(x-h)^2+k
h=-3, k=-8
y=a(x+3)^2-8
sub (-4,-5)
-5=a(-4+3)^2-8
a=3
y=3(x+3)^2-8
