Answer:

78.5 square units

Step-by-step explanation:

$d = 10 \implies \: r = \frac{10}{2} = 5 \\ area \: of \: circle \\= \pi {r}^{2} \\ = 3.14 \times {5}^{2} \\ = 3.14 \times 25 \\ = 78.5 \: {units}^{2} \\$

Step-by-step explanation:

Use this formula: A = πr^2

1) Plug in: A = π x 5^2

* I got 5 from the diameter. Whatever the number is, the radius will always be half*

2) A = π x 25

3) 3.14 x 25 is 78.5 units^2

A graph of quadratic function y = f(x) is shown below.

umka21 [38]

Answer:

{f|0 ≤ f(x)}; x² - 4x + 5

Step-by-step explanation:

To find the Quadratic Equation, plug the vertex into the Vertex Equation FIRST, y = a(x - h)² + k, where (h, k) → (2, 1) is the vertex, plus, -h gives you the OPPOSITE terms of what they really are, and k gives you the EXACT terms of what they really are: (x - 2)² + 1. Doing this will give you the Quadratic Equation of x² - 4x + 5. You understand now?

What is the length of the rectangle?

gregori [183]

Step-by-step explanation:

$area \: of \: rectangle \: = 60 \: {yards}^{2} \\ \therefore \: (w + 4) \times \: w = 60\\ \\ \therefore \: {w}^{2} + 4w -60 = 0 \\ \\ \therefore \: {w}^{2} + 10w - 6w -60 = 0 \\ \\ \therefore \: w({w} + 10) - 6(w + 10)= 0 \\ \\ \therefore \: ({w} + 10) (w- 6)= 0 \\ \therefore \: {w} + 10 = 0 \: or \: w- 6 = 0 \\ \therefore \: {w} = - 10 \: or \: w = 6 \\ \because \: sides \: of \: rectangle \: cant \: be \: negative \\ \therefore \: w \neq \: - 10 \\ \\ \therefore \: w = 6 \\ \\ \therefore \: w + 4 = 6 + 4 = 10 \\ \\ length \: of \: rectangle \: = 10 \: yards.$
