Answer 1

Step-by-step explanation:

geometric sequence means that every term is created by multiplying the previous term by a constant factor.

we can see the constant factor directly, I am sure, but let's do it formally correct :

-1/8 × f = -1/4

f = -1/4 / -1/8 = -1/4 × -8/1 = -8/-4 = 2

so, yes, every new term of the sequence is created by multiplying the previous term by 2.

a0 = -1/8

a1 = a0 × 2 = -1/8 × 2 = -2/8 = -1/4

a2 = a1 × 2 = a0 × 2×2 = -1/8 × 2×2 = -1/8 × 4 = -4/8 = -1/2

...

an = a0 × 2^n = -1/8 × 2^n

a6 = -1/8 × 2⁶ = -1/8 × 64 = -8

so, the only questing is, where does your teacher start the count for such a geometric sequence ?

do you call the first term a0 or a1 ?

my solution above starts with a0.

but if it should start with a1, then we need to reduce the exponents of 2 by 1 :

an = -1/8 × 2^(n-1)

and a6 would be

a6 = -1/8 × 2⁵ = -1/8 × 32 = -4

Solve the equation for x.

32(x − 8) = 14x + 3

Answers

x = 3 13/18. 3 13/18

The solution is 14.38

The value of x from the equation 32 (x − 8) = 14x + 3 is x = ( 14 7/18 )

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

32 (x − 8) = 14x + 3   be equation (1)

Now , on simplifying the equation , we get

32 ( x ) - 32 ( 8 ) = 14x + 3

32x - 256 = 14x + 3

Adding 256 on both sides of the equation , we get

32x = 14x + 259

Subtracting 14x on both sides of the equation , we get

18x = 259

Divide by 18 on both sides of the equation , we get

x = 259/18

The value of x = 14.38

Therefore , the value of x = 14.38 or 14 7/18

Hence , The value of x from the equation is x = ( 14 7/18 )

Step-by-step explanation:

Find the length of each side using the Distance Formula.

Find the length of side HA.

HA=(−10−(−6))2+(4−(−2))2−−−−−−−−−−−−−−−−−−−−−−−√

=(−4)2+(6)2−−−−−−−−−−√

=16+36−−−−−−√

Find the length of side AT.

AT=(−6−(−10))2+(6−4)2−−−−−−−−−−−−−−−−−−−−√

=(4)2+(2)2−−−−−−−−−√

=16+4−−−−−√

=20−−√=25–√

Find the length of side TC.

TC=(−2−(−6))2+(4−6)2−−−−−−−−−−−−−−−−−−−√

=(4)2+(−2)2−−−−−−−−−−√

=16+4−−−−−√

=20−−√=25–√

Find the length of side HC.

HC=(−2−(−6))2+(4−(−2))2−−−−−−−−−−−−−−−−−−−−−−√

=(4)2+(6)2−−−−−−−−−√

=16+36−−−−−−√

=52−−√=213−−√

Therefore, HA=HC=213−−√ and AT=TC=25–√.

Since there are two pairs of congruent consecutive sides, HATC is a kite by definition.

Find the perimeter of the kite as the sum of the four sides.

P=213−−√+25–√+25–√+213−−√=45–√+413−−√ units

To find the area of the kite, first find the lengths of the diagonals AC and TH using the Diatance Formula.

The figure shows the same quadrilateral H A T C as in the beginning of the task. Diagonal A C is perpendicular to diagonal T H.

Find the length of diagonal AC.

AC=(−2−(−10))2+(4−4)2−−−−−−−−−−−−−−−−−−−−√

=(8)2+(0)2−−−−−−−−−√

=64−−√=8

Find the legth of diagonal TH.

TH=(−6−(−6))2+(−2−6)2−−−−−−−−−−−−−−−−−−−−−√

=(0)2+(−8)2−−−−−−−−−−√

=64−−√=8

Find the area of the kite using the formula for the area of a kite, A=12d1d2.

Substitute 8 for d1 and 8 for d2.

A=12(8)(8)=32 units2

Therefore, the perimeter of the kite is 45–√+413−−√ units and the area is 32 units2.

A city has a population of 210,000 people. Suppose that each year the population grows by 4.25%. What will the population be after
13 years?
Use the calculator provided and round your answer to the nearest whole number

Answers

Answer:

Approximately 494,314 people

This is an exponential growth question, specifically population growth. We will use the following equation to help us solve this situation:

P(t) = a(1+r)t

P(t) = total population (??)

a = initial population = 260,000

r = growth factor (the percent as a decimal) = 0.055

1 + r = 1 + 0.055 = 1.055

t = time in years = 12

So, we can substitute all our information and solve:

P(12) = 260,000(1.055)12 = 494,313.95

Rounding to the nearest whole person, 494,314 people in 12 years.

write the factored equation of the following 6th degree polynomial with intercept at (0, 576)

Answers

Check the picture below on the left-hand-side.

we know the degree of the polynomial will be 6, so the exponents of its factors must add up to 6.

now, we know that at -4 and -1 it has an odd multiplicity, so the exponent of that factor could be either 3 or 1 hmmm  so which is it?

well, when the graph cross the axis straight through, it'd be a multiplicity of 1, when it leans a bit on the axis, like it does on -4, the multiplicity will be larger than 1, so then

[tex]\begin{cases} x=-4\implies &x+4=0\\ x=-1\implies &x+1=0\\ x=3\implies &x-3=0 \end{cases}\qquad \implies a\stackrel{odd\qquad odd\qquad even}{(x+4)^3(x+1)^1(x-3)^2}=y \\\\\\ \stackrel{\textit{we also know that}}{x=0\qquad y=576}\implies a(0+4)^3(0+1)(0-3)^2=576\implies a(64)(1)(9)=576 \\\\\\ 576a=576\implies a=\cfrac{576}{576}\implies a=1~\hfill \begin{array}{llll} 1\stackrel{odd\qquad odd\qquad even}{(x+4)^3(x+1)^1(x-3)^2}=y \\\\\\ \boxed{(x+4)^3(x+1)^1(x-3)^2=y} \end{array}[/tex]
