Answer:

[tex]x = -2, x = \frac{1}{6}[/tex]

completing square method:

Factorise :

[tex]\qquad \sf \: { \dashrightarrow {6x}^{2} + 4x= 2 - 7x}[/tex]

[tex]\qquad \sf \: { \dashrightarrow {6x}^{2} + 4x + 7x - 2 =0}[/tex]

[tex]\qquad \sf \: { \dashrightarrow {6x}^{2} + 11x - 2 =0}[/tex]

[tex]\qquad \sf \: { \dashrightarrow {6x}^{2} + 12x - x - 2 =0}[/tex]

[tex]\qquad \sf \: { \dashrightarrow {6x}^{} (x+ 2) -1( x + 2 )=0}[/tex]

[tex]\qquad \sf \: { \dashrightarrow ({6x}^{} - 1) (x+ 2) =0}[/tex]

[tex]\qquad \sf \: { \therefore 6x - 1=0} [/tex]

[tex] \qquad \sf \: \dashrightarrow6x =1 [/tex]

[tex]\qquad \sf \: { \dashrightarrow x= \dfrac{1}{6} }[/tex]

Answer:

the system will be worth $1892.25 after 2 years.

Explanation:

as the value decreases: [tex]\sf A = P(1 - \frac{r}{n})^{nt}[/tex] ......notice the ' - '  as its *decreases*

given:

solve:

[tex]\sf A = 2500(1 - \frac{0.13}{1})^{1*2}[/tex]

[tex]\sf A = 1892.25[/tex]

another way of doing it easily is:

[ $2500 * (100- 13)% ] * (100- 13)% = $1892.25

Use compound interest formula

[tex]\\ \rm\hookrightarrow P(1-r/100)^t[/tex]

[tex]\\ \rm\hookrightarrow 2500(1+0.13)^2[/tex]

[tex]\\ \rm\hookrightarrow 2500(0.87)^2[/tex]

[tex]\\ \rm\hookrightarrow 2500(0.76)[/tex]

[tex]\\ \rm\hookrightarrow 1900[/tex]

Answer:

8 crabs and 2 octopi

Step-by-step explanation:

Let c represent the amount of crabs and o represent the amount of octopi.

We can use this to set up a system of equations:

6c+8o=64

c=4o

We can solve this system using substitution. In this case, we can substitute 4o for c:

6(4o)+8o=64

24o+8o=64

Combine like terms

32o=64

Divide both sides by 32

o=2

Substitute 2 for o to solve for c:

c=4o=4(2)=8

There are 8 crabs and 2 octopi

The function f(x) = log4x does not have a y-intercept Because there is no power of 4 that is equal to 0.

Exponentiation's inverse function is the logarithm. That is, the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised in order to obtain that number x.

The logarithm counts the number of times the same factor appears in repeated multiplication in the simplest case.

Following are the reason why f(x) = log4x does not have a y-intercept

1. There is no power of 4 that is equal to 0.

2. Its inverse does not have any x-intercepts.

3. f(x) approaches negative infinity.

Hence  f(x) = log4x does not have a y-intercept.

Answer:

236 visitors purchased no costume.

202 visitors purchased exactly one costume.

40 visitors purchased more than one costume.

The total number of customers is, N = 236 + 202 + 40 = 478.

Let X denote the number of costumes purchased by the next person.

Compute the probability that the next person will purchase no more than one costume as follows:

Thus, the probability that the next person will purchase no more than one costume .

Casey will pay $156.00 in 3 years, the correct option is C.

The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned.

Given

Casey has a loan for $400 at a rate of 13% annually.

The interset Casey pay in three years for the loan is given by;

[tex]\rm Interest = Amount \times Rate \ of \ interest \times Time\\\\Interest = 400 \times 0.13 \times 3\\\\Interest = 156[/tex]

Hence, Casey will pay $156.00 in 3 years.

Answer:

10.8 =x

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

8.8 ^2 + 6.2 ^2 = x^2

77.44+38.44=x^2

115.88=x^2

Take the square root of each side

10.76475731=x

Round to 3 significant figures.

Answer: 3 and 192

Step-by-step explanation:

Answer:

1 % of 300 is 3, because 1 times 300 equals 300 divided by 100 is 3.

64 times 300 equals 19200 divided by 100 is 192.

Therefore the answer of 1 % of 300 is 64 times smaller than 64 % 300. Basically, 64 % of 300 = y and y= 64 (1 % of 300)

Step-by-step explanation:

The sum using summation notation will be - 312. The sum of the following progression is found by the formula as [tex]S_n = \frac{a(1 - r^n)}{(1 - r)}[/tex].

Geometric Progression (G.P.) is a sort of sequence in which each successive phrase is obtained by multiplying the prior term by a set number known as a common ratio.

This progression is also known as a pattern-following geometric sequence of integers. Here you may also learn about mathematical progression.

A non-zero value is obtained by multiplying the common ratio by each phrase to obtain the next term 5 - 15 45 - 135.. is an example of a geometric series with a common ratio of -3.

The common ratio will be;

[tex]\rm r= \frac{-15}{3} \\\\ \rm r= -5[/tex]

The first term is 3

So  the sum using summation notation will be;

[tex]S_n = \frac{a(1 - r^n)}{(1 - r)} \\\\ S_n = \frac{3(1 - (-5)^4)}{(1 - (-5))} \\\\ S_n =- 312[/tex]

Hence the sum using summation notation will be - 312.

The exact volume of the considered cone is given by: Option C: [tex]\dfrac{196}{3} \pi \: \rm in^3[/tex]

Suppose that the radius of the base of the considered right circular cone be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \dfrac{1}{3}\pi r^2 h \: \rm unit^3[/tex]

Right circular cone is the cone in which the line joining peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.

The missing figure of the cone is attached below.
