Answer:

CD = 4

Step-by-step explanation:

GH bisects CF means CF = 2 CD

CF = 2 CD

⇔ 2y - 2 = 2×(3y - 11)

⇔ 2y - 2 = 6y - 22

⇔ 22 - 2 = 6y - 2y

⇔ 20 = 4y

⇔ y = 5

Calculating CD ,For y = 5 :

CD = 3y - 11

= 3(5) - 11

= 15 - 11

= 4

A cylinder has a diameter of 6 feet. the volume of the cylinder is 36/5π cubic feet.

Anton [14]

Answer:

Height of cylinder is $\frac{4}{5}\ ft$ .

Step-by-step explanation:

Diameter of cylinder, D = 6 feet

Relation between Radius, R and diameter, D is given by:

$R = \dfrac{D}{2}$

So, radius, R = $\frac{6}{2} \Rightarrow 3$ feet

Let height of cylinder be $h$ feet.

Formula for volume of cylinder is given by:

$V = \pi R^{2} H$

Where, R is the radius of base of cylinder

and H is the height of cylinder

We are given that,

$V = \dfrac{36 \pi}{5} ft^{3}$

Using formula for volume, $V = \pi R^{2} H$

$\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft$

Hence, Height of cylinder is $\frac{4}{5}\ ft$ .

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle

romanna [79]

Answer:

54 in

Step-by-step explanation:

Use Pythagorean to find the missing side x of the triangle.

It is a hypotenuse with other sides 18 in and half of 15 in:

$x = \sqrt{18^2+(15/2)^2} =\sqrt{380.25} =19.5$

The perimeter is:

P = 2*19.5 + 15 = 54

Luden [163]

Answer:

Non-linear equations:

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

$3y=2^x$

Step-by-step explanation:

Linear equation: y = mx + b

Therefore, a linear equation has 2 variables that have no exponents.

So the non-linear equations are:

$y=x^2 +2x-3$ (this is a quadratic equation - polynomial with degree 2)

$3y=2^x$ (this is an exponential equation)
