This is algebra please help

Ghella [55]

Answer:

1/8 and 1/16

Step-by-step explanation:

The negative exponent just means to right the negative inverse.

For example:

4^-2 means 4^2 but in a fraction

the answer would be 1/16

(Sketch the graph x^2-7x+12=0

Nonamiya [84]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$x^{2} -7x+12=0$

This is a vertical parabola open upward (because the leading coefficient is positive)

The vertex is a minimum

step 1

Find the vertex of the quadratic equation

Convert the equation in vertex form

Complete the squares

$(x^{2} -7x+3.5^2)+12-3.5^2=0$

$(x^{2} -7x+12.25)+12-12.25=0$

$(x^{2} -7x+12.25)-0.25=0$

Rewrite as perfect squares

$(x-3.5)^{2}-0.25=0$

The vertex is the point (3.5,0.25)

step 2

Find the x-intercepts

The x-intercepts are the values of x when the value of the function is equal to zero

we have

$(x-3.5)^{2}-0.25=0$

solve for x

$(x-3.5)^{2}=0.25$

square root both sides

$(x-3.5)=\pm0.50$

$x=3.5\pm0.50$

$x=3.5+0.50=4$

$x=3.5-0.50=3$

therefore

The x-intercepts are the points (3,0) and (4,0)

step 3

Find the y-intercept

The y-intercept is the value of y when the value of x is equal to zero

we have

$y=x^{2} -7x+12$

For x=0

$y=(0)^{2} -7(0)+12$

$y=12$

The y-intercept is the point (0,12)

step 4

Graph the quadratic equation

we have

The vertex (3.5,0.25)

The x-intercepts (3,0) and (4,0)

The y-intercept (0,12)

using a graphing tool

Plot the points and draw the figure

What is the coefficient of the last term in the binomial expansion of (x 1)9? 0 1 9 10

alekssr [168]

The coefficient of the last term in the binomial expansion is 1.

Given term is (x + 1)⁹.

The algebraic expansion of a binomial's powers is expressed by the binomial theorem or binomial expansion. The process of expanding and writing terms that are equal to the natural number exponent of the sum or difference of two terms is known as binomial expansion.

The binomial expansion formula for (a + b)ⁿ= ⁿC₀(aⁿb⁰)+ⁿC₁(aⁿ⁻¹b¹)+ⁿC₂(aⁿ⁻²b²)+ⁿC₃(aⁿ⁻³b³)+...............+ⁿCₙ(a⁰bⁿ)

Here, a = x, b = 1 and n = 9.

Substituting the values in the formula,

⁹C₀(x⁹{1}₀)+⁹C₁(x⁹⁻¹{1}¹)+⁹C₂(x⁹⁻²{1}²)+⁹C₃(x⁹⁻³{1}³)+......+⁹C₉(x⁰{1}⁹)

The last term is ⁹C₉(x⁰{1}⁹)

The coefficient of the last term = ⁹C₉ = 1.

Hence, the coefficient of the last term in the binomial expansion of (x+1)⁹ is 1.
