HELP!!! Find the area of the shape shown

Mathematics
1 answer:
Blizzard [7]3 years ago
3 0

Answer:

12 square units

Step-by-step explanation:

We can break this shape into three parts, the left triangle, the middle square, and the right triangle. The left triangle has area of 2 square units, because 1/2(2x2) is 2. The middle square has 4 square units because 2x2 is 4. The right triangle has 6 square units because 1/2(6x2) is 6.

Adding the area of all the parts we get 12 square units.

Assuming that a 90° arc has an exact length of , find the length of the radius of the circle.
fiasKO [112]
If the exact length is s, you have
.. s = r*θ . . . . θ = π/2
.. r = s/θ
.. r = 2s/π

Fill in the exact length for "s" in the formula and compute to find the radius.

Help please! This has to do with the Pythagorean theorem.
Alex Ar [27]
The answer is 14.87.
a^2+b^2=c^2

10^2+11^2=c^2

100+121=c^2

221=c^2

Square root both sides

14.87=c
Hope this helps!!

Step-by-step explanation:

let the lengths of sides=x (each)

x²+x²=(10√2)²

2x²=100×2

F(x)= -x over x^2+5 on the domain [0,4]
BartSMP [9]
If you're asking for extrema, like the previous posting

well

\bf f(x)=\cfrac{-x}{x^2+5}
\\\\\\
\cfrac{df}{dx}=\cfrac{(x^2+5)+2x^2}{(x^2+5)^2}\implies \cfrac{df}{dx}=\cfrac{5+3x^2}{(x^2+5)^2}\impliedby 
\begin{array}{llll}
using\ the\\
quotient\ rule
\end{array}

like the previous posting, since this rational is identical, just that the denominator is negative, the denominator yields no critical points

and the numerator, yields no critical points either, so the only check you can do is for the endpoints, of 0 and 4

f(0) = 0        <---- only maximum, and thus absolute maximum

f(4) ≈ - 0.19  <----  only minimum, and thus absolute minimum
