Answers

The area of the parallelogram is given by A = 17.32 feet²

Given data ,

Let the area of the parallelogram be represented as A

Now , the value of A is

Let the height of the parallelogram be h

where from the trigonometric relation , we get

sin 60° = h / 4

On simplifying , we get

h = 4 ( √3/2 )

h = 2√3 feet

Now , the area of parallelogram = base x height

A = 2√3 ( 5 ) feet²

A = 10√3 feet²

A = 17.32 feet²

Hence , the parallelogram has an area of A = 17.32 feet²

The average speed of a golden eagle is 30 mph and the average speed of a peregrine falcon is 48 mph. How far will the peregrine falcon fly in the time it takes the eagle to fly 40 miles?

Answers

The peregrine falcon flies in the time it takes the eagle to fly 40 miles is 64 miles away.

What is the average speed?

The average speed is the total distance traveled by the object in a particular time interval.

The average speed is a scalar quantity.

The average speed of a golden eagle is 30 mph and the average speed of a peregrine falcon is 48 mph.

The time to fly 40 miles (that time is x):

miles        hours

30      ⇒       1

40      ⇒       x

We use the ruleof three which is to multiply the cross quantities on the table and divide by the remaining quantity:

x = 40(1)/30

x = 4/3 hour

it takes the eagle 4/3  flies to fly 40 miles.

Now we use the velocity of the falcon: 48mph, which can also be represented as:

miles        hours

48      ⇒       1  

and we need the distance in miles that the falcon flies in 4/3 hours :

miles        hours

48      ⇒       1

x        ⇒       4/3

Again we use the rule of three (multiply cross quantities and divide by the remainingquantity)

x = (48)× (4/3)

x = 64 miles

Hence, the peregrine falcon flies in the time it takes the eagle to fly 40 miles is 64 miles away.

Find f(5). f(x) = x2 +2x

Answers

Answer:

f(5) = 35

Step-by-step explanation:

In any function f(x), x is the input and f(x) is the output

Example:

f(x) = 2x + 3, find f(a)

That means we need to find value of f(x) at x = a, so substitute x by a

f(a) = 2(a) + 3 = 2a + 3

f(a) = 2a + 3

Let us use the same way to solve our question

f(x) = x² + 2x

→ We need to find f(5), so substitute x by 5

∴ f(5) = (5)² + 2(5)

∴ f(5) = 25 + 10

→ Do addition

f(5) = 35

Can you show me how to solve this problem: a. ) 16=4 to the 3rd power x -7

Answers

We assume you mean
\ \ \display{16=4^(3x-7)}
This is solved by writing 16 as a power of 4 and equating exponents.
\ 4^(2)=4^(3x-7)
  2 = 3x - 7 . . . . . equate exponents
  9 = 3x . . . . . add 7
  3 = x . . . . . divide by 3

The solution is x = 3.
