Answer:

Step-by-step explanation:

h(a) = 5x-2

h(5) = 5(5)-2

h(5) = 25-2

h(5) = 23

Answer:

Step-by-step explanation:

Plug in 5 as x

h(x) = 5x - 2

h(5) = 5(5) - 2

h(5) = 25 - 2

h(5) = 23

So, h(5) = 23

Which of the following are incorrect expressions for slope?

vfiekz [6]

Answer:

Option B and C are correct.

$\frac{x_2-x_1}{y_2-y_1}$

$\frac{run}{rise}$ are the expression incorrect for slope

Step-by-step explanation:

Slope is defined as the change in the dependent variable relative to the change in the dependent variable

or the ratio of the horizontal changes to vertical changes between any two points on the graph of the line.

The vertical changes between any two points is rise

The horizontal changes between any two points is run.

Formula for slope is given by:

For any two points $(x_1, y_1)$ and $(x_2, y_2)$

then slope is:

$\text{Slope} =\frac{rise}{run}= \frac{y_2-y_1}{x_2-x_1}$

or we can write this as:

Δy = $y_2-y_1$

Δx = $x_2-x_1$

⇒ $\text{Slope} = \frac{\triangle y}{\triangle x}$

Therefore, the expression which are incorrect for slope are;

$\frac{x_2-x_1}{y_2-y_1}$

$\frac{run}{rise}$

A cylinder fits inside a square prism as shown. For every cross section, the ratio of the area of the circle to the area of the

kolbaska11 [484]

Answer:

Volume of cylinder = $\pi r^2h$

Step-by-step explanation:

Given : A cylinder fits inside a square prism.

To find : The volume of cylinder

Solution : Refer the attached graph.

Area of circle = $\pi r^2$

Area of square = $s^2$

Side of square = diameter of circle= $D^2$

Diameter = 2r

∴ Area of square= $2r^2=4r^2$

$\frac{Area of circle}{Area of Square}=\frac{\pi r^2}{4r^2}=\frac{\pi}{4}$

Area of circle is $\frac{\pi }{4}$ of area of square.

Volume is always = area × height

Volume of prism = Area of square × h = $4r^2h$

Volume of cylinder = Area of circle × h = $\pi r^2h$

Now, rate

$\frac{Volume of cylinder}{Volume of prism}=\frac{\pi r^2h}{4r^2h}=\frac{\pi}{4}$

⇒Volume of cylinder is $\frac{\pi }{4}$ of Volume of prism.

Volume of Cylinder = $\frac{\pi }{4}\times Volume of prism$

Volume of cylinder = $\frac{\pi }{4}\times 4r^2h$

Volume of cylinder = $\pi r^2h$

<h3>Answer</h3>

a = 36

b = √3/5

════════════════════

<h3>Known </h3>

Adjuscent = 12√3

════════════════════

<h3>Question</h3>

Opposite = ?

Hypotenuse = ?

════════════════════

• finding a - opposite

#use tan formula

tan(∅) = opposite / adjuscent

tan(60) = opposite / 12√3

opposite = tan(60) × 12√3

opposite = 36

•finding b - hypotenuse

#use cos formula

cos(∅) = adjuscent / hypotenuse

cos(60) = 12√3 / hypotenuse

hypotenuse = 12√3 : cos(60)

hypotenuse = √3/5
