Which points are on graph of f(x)=2(0.5)^x

Answers

Answer 1

Answer: Since no points are given, you can make your own points.
Put x=0, then f(x)=2(0.5)^0=2*1=2 => (0,2)
Put x=1, then f(x)=2(0.5)^1=2(0.5)=1 => (1,1)
Put x=2, then f(x)=2(0.5)^2=2(1/4)=1/2 => (2, 1/2)

What information is marked in the diagram ?

-- The angles in the lower left corner of each triangle are
right angles, so the triangles are right triangles.

-- The angles in the lower right corner of each triangle are equal.

-- The slanted sides of both triangles are equal. (Since the triangles
are right triangles, the slanted sides are their hypotenees.)

If the hypotenuse and one acute angle of a right triangle are
equal respectively to the hypotenuse and one acute angle of
another right triangle, that's enough to prove that the triangles
are congruent.

2. The line BC in the figure above is the ___ of the cylinder.A. slant height
B. axis
C. altitude
D. vertex

Answers

Answer:

BC denotes the axis of the cylinder in the given figure.

Step-by-step explanation:

Given an oblique cylinder. It is three dimensional shape having sides not perpendicular to the base. it means it is leaning toward one side left or right as shown in figure below.

We have to determine what BC denotes.

Height is always perpendicular to the base so the given line BC is the axis of the cylinder . When there is a slant to the cylinder axis is also not perpendicular to the base.

Thus, BC denotes the axis of the cylinder in the given figure.

The line BC in the figure above is the AXIS of the cylinder.

Axis of the cylinder is the line formed by the centers of the bases of a cylinder.

Which is equivalent to (4xy – 3z)2, and what type of special product is it?16x2y2 + 9z2, the difference of squares
16x2y2 + 9z2, a perfect square trinomial
16x2y2 – 24xyz + 9z2, the difference of squares
16x2y2 – 24xyz + 9z2, a perfect square trinomial

Answers

(4xy - 3z)²

(4xy - 3z)(4xy - 3z)
4xy(4xy - 3z) - 3z(4xy - 3z)
16x²y² - 12xyz -12xyz + 9z²

16x²y² - 24xyz + 9z², a perfect square trinomial.

The correct option is $\boxed{{\mathbf{Option D}}}$ .

Further explanation:

The binomial algebraic expression is an algebraic expression that consists two terms and it is separated by plus or minus.

Binomial expression can be mathematically expressed as,

$a + b$

The trinomial algebraic expression is an algebraic expression that consists three terms and it is separated by plus or minus.

Trinomial expression can be mathematically expressed as,

$a + b + c$

Here, $a,b{\text{ and }}c$ are the real numbers.

The square of the binomial $a + b$ can be written as,

${\left( {a + b} \right)^2} = \left( {a + b} \right)\left( {a + b} \right)$

Given:

The given algebraic expression is ${\left( {4xy - 3z} \right)^2}$ .

Step by step explanation:

Step 1:

The square of the binomial $a + b$ can be written as,

${\left( {a + b} \right)^2} = \left( {a + b} \right)\left( {a + b} \right)$

Similarly, the expression ${\left( {4xy - 3z} \right)^2}$ can be written as,

$\begin{aligned}{\left( {4xy - 3z} \right)^2} &= \left( {4xy - 3z} \right)\left( {4xy - 3z} \right) \n&= 4xy\left( {4xy - 3z} \right) - 3z\left( {4xy - 3z} \right) \n\end{aligned}$

Step 2:

The distributive property can be used to solve the square of the binomial.

The distributive property can be expressed as,

$a\left( {b + c} \right) = ab + ac$

Now apply the distributive property to solve the expression ${\left( {4xy - 3z} \right)^2}$ .

$\begin{aligned}{\left( {4xy - 3z} \right)^2} &= 4xy\left( {4xy - 3z} \right) - 3z\left( {4xy - 3z} \right) \n&= 16{x^2}{y^2} - 12xyz - 12xyz + 9{z^2} \n&= 16{x^2}{y^2} - 24xyz + 9{z^2} \n\end{aligned}$

Therefore, the expression $16{x^2}{y^2} - 24xyz + 9{z^2}$ is the perfect square of the binomial $\left( {4xy - 3z} \right)$ .

The expression $16{x^2}{y^2} - 24xyz + 9{z^2}$ is the trinomial.

Thus, option D a perfect square trinomial $16{x^2}{y^2} - 24xyz + 9{z^2}$ is correct.
