Harrizon [31]3 years ago
7 0

Step-by-step explanation:

sec⁴A + tan⁴A = 1 + (2tan²A/cos²A)

LHS = sec⁴A + tan⁴A

= (sec²A)² + (tan²A)² {using formula of a²+b²)

= (sec²A-tan²A) + 2tan²A.sec²A

= 1 + {2tan²A.(1/cos²A)}

= 1 + (2tan²A/cos²A)

The perimeter of a parallelogram is 56 meters the width of the parallelogram is 8 meters less than its length find the length of
Dimas [21]

Answer:

length = 18 mt

Width = 10 mt

Step-by-step explanation:

Let the length of the field be x

width of the field be y

Hence

P=2(x+y)

P=56 (given)

56=2(x+y)

Dividing both sides by 2 we get

x+y=28   ---(A)

Also given that width of the parallelogram is 8 meters less than its length

Hence

y=x-8

or x-y=8   ---(B)

Adding A and B

2x=36

x=18

y=x-8

y=18-8=10

Hence length = 18 mt

Width = 10 mt

Alekssandra [29.7K]

Answer:

100000 = 8 (4) ^t

Step-by-step explanation:

We are multiplying by 4 each time

y = a (4)^t

The initial amount is 8

y = 8 (4)^t

We want to get to 100000

100000 = 8 (4) ^t
