Find the value of x. PLEASE HELP ME!!!!!!!!!!

murzikaleks [220]

Solution:

Step-1: Find the missing side length using Pythagoras theorem:

115² = 69² + x²
=> 13225 = 4761 + x²
=> 13225 - 4761 = x²
=> 8464 = x²
=> x = √8464 = 92

Step-2: Find the area of the rectangle:

Area of rectangle = LB
=> 69 x (92 + 100)
=> 69 x 192
=> 13248 units²

Answer:

$94.2m^2$

Step-by-step explanation:

The formula for SA of a cone is...

$\pi (r)(h)+\pi (r)^2$

Fill in what you have

$\pi (3)(7)+\pi (3)^2$

Pi is 3.14 for our purposes

$\pi (3)(7)+\pi (3)^2\\3.14(3)(7)+3.14(3)^2$

Then solve

$21(3.14)+9(3.14)\\\\94.2m^2$

Jeremy and Arnold are working on a project for math class in which they are to identify the quadratic equation that represents a

denis23 [38]

Answer:

The parabola generated by the expression :

$y=x^2-2x+3$

is the one that better represents a rain gauge above the ground.

Step-by-step explanation:

The function:

a) $y=x^2+11x+24$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: below

So, the parabola doesn't depict a rain gauge off the ground

b) $y=-x^2-6x-8$

Direction of parabola: branches pointing down

Location of vertex relative to x-axis: above

So, the parabola doesn't depict a rain gauge off the ground

c) $y=x^2-2x+3$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: two units above

So, the parabola depicts a rain gauge off the ground

d) $y=x^2+4x+4$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: right on the x-axis

So, the parabola doesn't depict a rain gauge off the ground (this is sitting on the ground)

e) $y=3x^2+21x+30$

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: below

So, the parabola doesn't depict a rain gauge off the ground
