What is the value of sin2a + cos2a + sec2a-tan2a <br> Please
Artemon [7]

Answer:

2

Step-by-step explanation:

sin²a + cos²a + sec²a - tan²a

sin²a + cos²a = 1

1 + tan²a = sec²a

So, sec²a - tan²a = 1

sin²a + cos²a + sec²a - tan²a

= 1 + 1 = 2

Oliga [24]
We have that

<span>Write an equation of a line that passes through the point (2, 3) and is parallel to the line y = (3/2)x +5

parallel lines are the same slope
then
m=(3/2)

step 1

find the equation of a line with
m=3/2  and point (2,3)

y-y1=m*(x-x1)----------> y-3=(3/2)*(x-2)------> y=(3/2)x

the answer is
y=(3/2)x
</span><span>y = 3 over 2 x

Airida [17]

Answer:

184 feet

Step-by-step explanation:

To answer this question you need to convert the 48 inches first to feet, as fabric is sold by the foot. 48 in converts to 4 ft which is what we will use for each curtain. Since we need 46 curtains we will multiply 46 curtains by 4 feet which will give our answer of 184 feet.
