Answer:

Perimeter = 12.5 cm

Step-by-step explanation:

<h2>Perimeter of quarter cirlce:</h2>

    d = 7 cm

    \sf \boxed{\text{Circumference of quarter circle =$\dfrac{1}{4} \pi d$}}

                                                       \sf = \dfrac{1}{4}*\dfrac{22}{7}*7\\\\ =\dfrac{11}{2}\\\\ = 5.5 \ cm

   Perimeter = radius + radius + circumference of quarter circle

                     = diameter + circumference of the quarter circle.

                      = 7  + 5.5

                      = 12.5 cm

The zeroes of f(x) = x3 + 3x2 + 2x are <br> .
Vaselesa [24]

The zeros of the function f(x) = x^3 + 3x^2 + 2x are x = 0, x = -1 and x = -2

<h3>How to determine the zeros of the function?</h3>

The function is given as:

f(x) = x^3 + 3x^2 + 2x

Factor out x in the above function

f(x) = x(x^2 + 3x + 2)

Set the function to 0

x(x^2 + 3x + 2) = 0

Factorize the expression in the bracket

x(x + 1)(x + 2) = 0

Split the expression

x = 0, x + 1 = 0 and x + 2 = 0

Solve for x

x = 0, x = -1 and x = -2

Hence, the zeros of the function f(x) = x^3 + 3x^2 + 2x are x = 0, x = -1 and x = -2

A=755y/t^2 <br> Solve for y.
timofeeve [1]

Answer:

y = At²/755

Step-by-step explanation:

A = 755y/t²

multiply both sides by t²

At² = 755y

Divide both sides by 755

At²/755 = y

Flip

y = At²/755
