Answer:

Step-by-step explanation:

Perimeter equals the lengths of each side or edge added together

The perimeter of a square is P = 4 × side all four sides ar the same length

The perimeter of a rectangle is P = 2×L + 2×W

Perimeter of a circle is P = π × r

The perimeter here is a random polygon, but still just add up all sides to get your answer.

P = 47 + 50 + 9 + 30 + 30 + 30 + 9 +50

= 47 + 2×50 + 2×9 + 3×30

= 47 + 100 + 18 + 90

= 190 + 65

P = 255 yards I assume there is a typo somewhere in the question

Trevor is making 2/3 of a recipe for chicken noodle soup. He adds ½ cup of chopped celery. The equation 2/3 c = 1/2 can be used

Nikitich [7]

Answer:

Cups of chopped celery in original recipe = $\frac{3}{4}\ cups$

Step-by-step explanation:

Given that:

Trevor is making 2/3 of a recipe

Number of cups of chopped celery used = 1/2 cup

The following equation can be used to find the original number of cups of chopped celery used in recipe.

$\frac{2}{3}c=\frac{1}{2}$

Multiplying both sides by 3/2

$\frac{3}{2}*\frac{2}{3}c=\frac{1}{2}*\frac{3}{2}\\\\c= \frac{3}{4}\\$

Hence,

Cups of chopped celery in original recipe = $\frac{3}{4}\ cups$

Find a and b so that f(x) = x^3 + ax^2 + b will have a critical point at (2,3).

Digiron [165]

Using the critical point concept, it is found that a = -3 and b = 7.

<h3>What are the critical points of a function?</h3>

The critical points of a function are the values of x for which:

$f^{\prime}(x) = 0$

In this problem, the function is:

$f(x) = x^3 + ax^2 + b$

Hence, the derivative is:

$f^{\prime}(x) = 3x^2 + 2ax$

Then:

$f^{\prime}(x) = 0$

$3x^2 + 2ax = 0$

$x(3x + 2a) = 0$

$x = 0$

$3x + 2a = 0$

$3x = -2a$

$x = -\frac{2a}{3}$

Since the critical point is at x = 2, we have that:

$-\frac{2a}{3} = 2$

$-2a = 6$

$2a = -6$

$a = -3$

Then:

$f(x) = x^3 - 3x^2 + b$

Critical point at (2,3) means that when $x = 2, y = 3$ , then:

$3 = 2^3 - 3(2)^2 + b$

$8 - 12 + b = 3$

$b = 7$
