Answer:

Step-by-step explanation:

circumference=2πr=6.28

r=6.28/2π=3.14/π=3.14/3.14=1

area=πr^2=π×1²=π=3.14 units²

The perimeter of a triangle is 47 feet. One side of the triangle is one foot longer than the second side. The third side is four

Ugo [173]

Answer:

The lengths of all three sides (in feet) are = 15, 14, and 18 feet

Step-by-step explanation:

Perimeter of Triangle = 47ft

Let the one side be 'x'

Side 1 = x

One side of the triangle is one foot longer than the second side

Side 2 = x - 1

The third side is four feet longer than the second side

Side 3 = (x - 1) + 4

Perimeter = sum of all sides

47 = x + (x - 1) + (x - 1) + 4

47 = x + x - 1 + x - 1 + 4

47 = 3x + 2

47 - 2 = 3x

45 = 3x

x = 15

substitute for x in each of the sides

Side 1 = x => 15 feet

Side 2 = x - 1 => 15 - 1 = 14 feet

Side 3 = (x - 1) + 4 => 14 + 4 = 18 feet

Answer:

The answer to your question is: 16x + 3

Step-by-step explanation:

Step 1 : f(x) = 8x² + 3x

f(x +h) = 8(x + h)² + 3( x + h)

f(x + h) = 8( x² + 2xh + h²) + 3( x + h)

f (x + h) = 8x² + 16xh + 8h² + 3x + 3h

Step 2 f(x+h) - f(x) = 8x² + 16xh + 8h² + 3x + 3h - ( 8x² + 3x)

= 8x² + 16xh + 8h² + 3x + 3h - 8x² -3x

= 16xh + 8h² + 3 h

Step 3 f(x + h) - f(x)/ h = h(16x + 8h + 3) /h

= 16x + 8h + 3

Step 4 lim f(x + h) - f(x)/ h = lim 16x + 8h + 3 = lim 16x + 8(0) + 3 = 16x + 3

h ⇒0 h ⇒0 h ⇒0

Divide 3/4)1/2 to give the answer

Dahasolnce [82]

The exact form will be 3/2 (if you reduce, how many times will one go into three? three times, two will go into 4 twice so that is one way to get the answer.) Decimal form is 1.5 and the mixed number form will be one and one half (or 1 1/2)
