You have a 300 feet side length square and you need to calculate the length of the diagonal. When you split the square along one diagonal you get triangles, so you can apply Pythagoras' Theorem, with the hypotenuse as the needed diagonal.
a²+b²=c²
300²+300²=c²
2*300²=c²
√(2*300²)=c
√(2) * √(300²)=c
√(2) * 300=c
c~424.26 ft which is the solution/option c

Hi there! 

The formula for the volume of a cone is V = 1/3(pi x r^2 x h). Using this formula, we can solve for the volume of the cone.

WORK:
V = 1/3(3.14 x 6.5^2 x 14)
V = 1857.31 / 3
V = 619.10 cm^3

ANSWER:
A) 619.10cm^3

Hope this helps!! :)

A spinner has 10 equally sized sections, 5 of which are gray and 5 of which are blue. The spinner is spun twice. What is the pro
zhenek [66]

Answer:

P(Gray\ and\ Blue) = \frac{1}{4}

Step-by-step explanation:

Given

Sections = 10

n(Gray) = 5

n(Blue) = 5

Required

Determine P(Gray and Blue)

Using probability formula;

P(Gray\ and\ Blue) = P(Gray) * P(Blue)

Calculating P(Gray)

P(Gray) = \frac{n(Gray)}{Sections}

P(Gray) = \frac{5}{10}

P(Gray) = \frac{1}{2}

Calculating P(Gray)

P(Blue) = \frac{n(Blue)}{Sections}

P(Blue) = \frac{5}{10}

P(Blue) = \frac{1}{2}

Substitute these values on the given formula

P(Gray\ and\ Blue) = P(Gray) * P(Blue)

P(Gray\ and\ Blue) = \frac{1}{2} * \frac{1}{2}

P(Gray\ and\ Blue) = \frac{1}{4}

The power generated by an electrical circuit (in watts) as function of its current x (in amperes) is modeled by: P(x)=-12x^2 +12
Minchanka [31]

Given:

The power generated by an electrical circuit (in watts) as function of its current x (in amperes) is modeled by:

P(x)=-12x^2+120x

To find:

The current that will produce the maximum power.

Solution:

We have,

P(x)=-12x^2+120x

Here, leading coefficient is negative. So, it is a downward parabola.

Vertex of a downward parabola is the point of maxima.

If a parabola is f(x)=ax^2+bx+c, then

Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)

In the given function, a=-12 and b=120. So,

-\dfrac{b}{2a}=-\dfrac{120}{2(-12)}

-\dfrac{b}{2a}=-\dfrac{120}{-24}

-\dfrac{b}{2a}=5

Putting x=5 in the given function, we get

P(5)=-12(5)^2+120(5)

P(5)=-12(25)+600

P(5)=-300+600

P(5)=300

Therefore, 5 watt current will produce the maximum power of 300 amperes.
