the angle with the equation (9x+11) is a vertical angle with the 56 degree angle.

This means the two angles are the same.

Set the equation to equal 56 and solve for X:


9x+11 = 56

Subtract 11 from each side:

9x = 45

Divide both sides by 9"

x = 45/9

x = 5

The rectangular piece of property measures 8 mi by 6 mi. find an equation for the ellipse if the path is to touch the center of
Artyom0805 [142]
The ellipse will be inscribed in the rectangle.
Because the rectangle measures 8 mi by 6 mi, the ellipse has
a = 8/2 = 4 mi (major axis)
b = 6/2 = 3 mi (minor axis)

The equation for the ellipse is
x^2/a^2 + y^2/b^2 = 1

That is
x^2/4^2 + y^2/3^2 = 1
x^2/16 + y^2/9 = 1

Answer:
x^2/16 + y^2/9 = 1

If a CONE has a DIAMETER of 10 centimeters and a Volume of 225 cubic centimeters, what is its approximate HEIGHT
ch4aika [34]

Answer:

The approximate height is 8.9 cm

Step-by-step explanation:

To find the height of a cone with a diameter of 10 cm and a volume of 225 cubic centimeter, we will follow the steps below;

first, write down the formula for finding the volume of a cone

v=πr²\frac{h}{3}

where v is the volume of the cone

r is the radius and h is the height of the cone

from the question given,

diameter = 10 cm   but       d=2r       this implies  that    r= \frac{d}{2}     r=   10/2   =    5cm

hence   r= 5cm

Also    v= 225 cm³

π  is a constant and is ≈ 3.14

We can now proceed to insert the values into formula and then solve for h

v=πr²\frac{h}{3}

225 ≈ 3.14 × 5² × \frac{h}{3}

225 ≈ 78.5 ×\frac{h}{3}

225 ≈ \frac{75.8 h}{3}

cross-multiply

675 = 75.8 h

divide both-side of the equation by 75.8

8.9 ≈ h

h≈ 8.9

Therefore, the approximate height is 8.9 cm

Classify each of the power functions based on their end behavior (increasing or decreasing) as x = ∞
Svetlanka [38]

Answer: right side behavior:

              f(x) is Decreasing

             g(x) is Increasing

             h(x) is Increasing

             j(x) is Decreasing

<u>Step-by-step explanation:</u>

The rules for end behavior are based on 2 criteria: Sign of leading coefficient and Degree of polynomial

<u>Sign of leading coefficient</u> (term with greatest exponent):

  • If sign is positive, then right side is increasing
  • If sign is negative, then right side is decreasing

<u>Degree of polynomial</u> (greatest exponent of polynomial:

  • If even, then end behavior is the same from the left and right
  • If odd, then end behavior is opposite from the left and right

f(x) = -2x²

  • Sign is negative so right side is decreasing
  • Degree is even so left side is the same as the right side (decreasing)

as x → +∞, f(x) → +∞  Decreasing

as x → -∞, f(x) → -∞   Decreasing

g(x) = (x + 2)³

  • Sign is positive so right side is increasing
  • Degree is odd so left side is opposite of the right side (decreasing)

as x → +∞, f(x) → +∞  Increasing

as x → -∞, f(x) → -∞   Decreasing

h(x)=-1+x^{\frac{1}{2}}\implies h(x)=x^{\frac{1}{2}}-1  

  • Sign is positive so right side is increasing
  • Degree is an even <u>fraction</u> so left side is opposite of the right side as it approaches the y-intercept (-1)

as x → +∞, f(x) → +∞  Increasing

as x → -∞, f(x) → -1    Decreasing to -1

j(x)=\dfrac{1}{2}(-x)^5\implies j(x)=\dfrac{1}{2}(-1)^5(x)^5\implies j(x)=-\dfrac{1}{2}x^5

  • Sign is negative so right side is decreasing
  • Degree is odd so left side is opposite of the right side (increasing)

as x → +∞, f(x) → +∞  Decreasing

as x → -∞, f(x) → -∞   Increasing

Find the equation of the line that has slope -5/6 and which passes through (-1,-6).
Sergeeva-Olga [200]
Just plug it into the formula

y-(-6)=-5/6(x-(-1))
y+6=-5/6(x+1)
y=-5/6(x)-5/6-6

The answer is: f(x)=-5/6(x)-41/6
