Area = (Pi)(Radius)^(2)

so

A = π(4.3)<span>²
A = </span>π(18.49)
A =  58.088 in/sq

(There should be a Pi button on your calculator)

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER
4vir4ik [10]

Answer:

480 inches squared

Step-by-step explanation:

The formula for the area of a rhombus is pq/2, where p and q are the diagonals. In the picture, half of a diagonal is 10 (which I am assuming 10 does not represent the whole diagonal), so all of the horizontal diagonal is 20.

Applying the Pythagorean Theorem to this, we get 10^2 + x^2 = 26^2. After simplifying, this becomes 100 + x^2 = 676, and therefore x = 24. Multiply this by 2 to get the full vertical diagonal, the area is simply 48*20/2 which is 480 inches squared.

Given f(x)=2x2−5x−3 and g(x)=2x2+x .<br> What is (fg)(x) ?
gizmo_the_mogwai [7]

Answer:

fourth option

Step-by-step explanation:

note that (\frac{f}{g} )(x)x) = \frac{f(x)}{g(x)}

\frac{f(x)}{g(x)} = \frac{2x^2-5x-3}{2x^2+x} ← factorise numerator/ denominator

= \frac{(x-3)(2x+1)}{x(2x+1)} ← cancel the common factor (2x + 1)

= \frac{x-3}{x} where x ≠ 0, - \frac{1}{2}
