Answer:

78.5yd^{2}

Step-by-step explanation:

The formula to find the area of a circle of is: A = \pi r^{2}

However, the question wants to use 3.14 instead of pi.

We need to find the radius. The radius of the circle is half the diameter. So, the radius to 5 yards.

Now we just plug in the formula.

A=3.14*(5yd)^{2} \\A=3.14*25yd^{2} \\A=78.5yd^{2}

The graph of which function will have a maximum and a y-intercept of 4?
stiv31 [10]

Answer:

<h2>f(x) = -x² + 2x + 4</h2>

Step-by-step explanation:

We have quadratic functions f(x) = ax² + bx + c.

c - y-intercept

If a > 0, then a parabola opens up and has a minimum in a vertex.

If a < 0, then a parabola opens down and has a maximum in a vertex.

The function has maximum and y-intercept of 4:

a < 0 and c = 4

Let A = Aaron's age today and M = Maria's age today.
kondor19780726 [428]

Aaron is 4 years and Maria is 14 years old.

A = Aaron's age today

M = Maria's age today.

a. The equation based on the statement given will be:

M = A + 10

b. Maria's age based on the statement in 6 years will be:

= (A + 10) + 6

= A + 16

c. Based on the information above, the equation to solve their ages will be:

A + 16 = 2(A + 6)

A + 16 = 2A + 12

Collect like terms

2A - A = 16 - 12

A = 4

Therefore, Aaron is 4 and Maria is 14 years.
