Answer: the shaded region is 1138.97m²

Step-by-step explanation:

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Considering the larger circle,

Radius = 11.6 + 10.7 = 22.3 m

Area = 3.14 × 22.3² = 1561.4906m²

Considering the smaller circle,

Radius = 11.6 m

Area = 3.14 × 11.6² = 422.5184m²

Area of the shaded region is area of the larger circle - area of the smaller circle. It becomes

1561.4906 - 422.5184 = 1138.97m² rounded up to the nearest hundredth

Hi,

$\frac{x^{a} }{x^{b} } =x^{a-b}$

$\frac{x^{7} }{x^{3} }= x^{7-3} = x^{4}$

$\frac{y^{5} }{y^{4} } = y^{5-4} = y^{1} = y$

A ball is thrown at an initial height of 7 feet with an initial upward velocity at 27 ft/s. The balls height h (in feet) after t

lianna [129]

Answer:

The height of ball is 17 ft at t=0.55 and t=1.14.

Step-by-step explanation:

The general projectile motion is defined as

$y=-16t^2+vt+y_0$

Where, v is initial velocity and y₀ is initial height.

It is given that the initial height is 7 and the initial upward velocity is 27.

Substitute v=27 and y₀=7 in the above equation to find the model for height of the ball.

$h(t)=-16t^2+27t+7$

The height of ball is 17 ft. Put h(t)=17.

$17=-16t^2+27t+7$

$0=-16t^2+27t-10$

On solving this equation using graphing calculator we get

$t=0.549,1.139$

$t\approx 0.55,1.14$

Therefore the height of ball is 17 ft at t=0.55 and t=1.14.

Pleae help thanks a bunch

zloy xaker [14]

Hello!

You use the Pythagorean theorem to solve this

$a^{2} + b^{2} = c^{2}$

Put in the values it tells you to

$a^{2} + 4.4^{2} = 5.5^{2}$

Square the numbers

$a^{2} + 19.36 = 30.25$

Subtract 19.36 from both sides

$a^{2} = 10.89$

Take the square root of both sides

a = 3.3

The answer is 3.3

Hope this helps!

QUICK! 20 points!

To find the inverse function, swap x x and y y , and solve the resulting equation for x x . If the initial function is not one-to-one, then there will be more than one inverse. So, swap the variables:

y=−x2−36 y = − x 2 − 36

becomes

x=−y2−36 x = − y 2 − 36 .

Now, solve the equation

x=−y2−36 x = − y 2 − 36 for y y .

y=−x−36‾‾‾‾‾‾‾‾√ y = − x − 36y=−x−36‾‾‾‾‾‾‾‾√ y = − − x − 36

ANSWER y=−x−36‾‾‾‾‾‾‾‾√ y = − x − 36 y=−−x−36‾‾‾‾‾‾‾‾√
