Step-by-step explanation:
(1 - cos²A)(1 + tan²A) = tan²A
1 + tan²A - cos²A - cos²A · tan²A = tan²A
1 + tan²A(1 - cos²A) - cos²A = tan²A
1 - cos²A + tan²A(sin²A) = tan²A
sin²A + tan²A(sin²A) = tan²A
sin²A (1 + tan²A) = tan²A
sin²A (sec²A) = tan²A
sin²A (1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → Proved

What is the asymptote of f(x)=2x-5
Answer:
No asymptote
Step-by-step explanation:
This equation is linear, so it will not have an astmptote.
Determine the intercepts of the line. Do not round your answers. 2 x + 5 y = − 6
The y-intercept for the line, 2x + 5y = -6, is: 1.2.
Equation of a Line in Slope-Intercept FormThe equation of a line can be represented in slope-intercept form as: y = mx + b."b" is the y-intercept.Given:
2x + 5y = -6
Rewrite in slope-intercept form
5y = -2x - 6
Divide both sides by 5y = -2/5x - 6/5
"b" = -6/5 = 1.2
Therefore, the y-intercept for the line, 2x + 5y = -6, is: 1.2.

Answer:
n = 3.16 units; p = 5 units
Step-by-step explanation:
to find the length of the lines you need to use the pythagorean theorem or a^2 + b^2 = c^2
in this case a is x, b is y, and c is the length
so for n it is:
1^2 + 3^2 = c^2 -->
1 + 9 = c^2 -->
10 = c^2
c = 3.16227766 or about 3.16 (this is n's length)
for p it is:
3^2 + 4^2 = c^2 -->
9 + 16 = c^2 -->
25 = c^2 -->
c = 5 (this is p's length)

In winter, the price of apples suddenly went up by $0.75 per pound. Sam bought 3 pounds of apples at the new price for a total of $5.88.
1. Write an equation to determine the original price per pound (p)
2. Find the original price per pound.
Answer:
$1.21Step-by-step explanation:
Original price = pNew price = p + 0.75Equation:
3(p + 0.75) = 5.88p + 0.75 = 5.88/3p + 0.75 = 1.96p = 1.96 - 0.75p = 1.213. What type(s) of symmetry is/are shown in the figure below!

I am cooking a recipe. It requires 7/2 of sugar. I only have a 1⁄4 cup to measure the sugar with. How many quarter cups would I need to measure the correct amount of
Answer:
14
Step-by-step explanation:
Convert [tex]\frac{7}{2}[/tex] to a fraction with a common denominator
[tex]\frac{7}{2} (\frac{2}{2} )=\frac{14}{4}[/tex]
You now divide the fractions to find the amount of correct measurements needed.
[tex]\frac{\frac{14}{4} }{\frac{1}{4} }[/tex] For dividing by a fraction it is the same a multiplying by its reciprocal.
This becomes [tex]\frac{14}{4} (\frac{4}{1} )=\frac{14}{4} (4)=14[/tex]
You will need 14 correct measurements.
