40

Step-by-step explanation:

Given :-

z = -1/4

Inputting the values :-

2/z + 3/z²

2/(-1/4) + 3/(-1/4)²

(2 x -4) + (3 x 16)

-8 + 48

= 40

Solution :-

40

Answer:

40

Step-by-step explanation:

[tex]\dfrac{2}{z}+\dfrac{3}{z^2}[/tex]

[tex]\textsf{if} \ z=-\dfrac14[/tex]

[tex]\implies \dfrac{2}{-\frac14}+\dfrac{3}{(-\frac14)^2}[/tex]

[tex]\implies -\dfrac{2}{\frac14}+\dfrac{3}{\frac{1}{16}}[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

Consider what y values you are getting by letting x = 5 and then letting x = 6.

when x = 5 , y = 20

y = m*5

20 = m*5                      Divide by 5

20/5 = m/5                  

4 = m

when x = 6 y = 24

y = mx

24 = m*6                     Divide by 6

24/6 = m

m = 4

So now we can be sure of our solution for x when y = 32

y = m*n

32 = 4*n                      Divide both sides by 4

32/4 = 4*n/4

n = 8

Answer: n = 8

Answer:

Answer:

$1.26

Step-by-step explanation:

total: 16.2 (3.24 * 5)

4.55 + 2.53 + 2.82 + 4.66 = 14.56

16.2 - 14.56 = 1.26

The price of the fifth item in W's bag is $1.55 if the mean price of all five items is $3.24.

A mean is one of the measures of central tendencies and is the average value of a group of observations. It is the ratio of the sum of all observations to the total number of observations.

The prices of the 4 items out of the 5 items W has bought are given as follows:

$4.55, $2.53, $2.82, $4.66

It is also given that the mean cost for each item is $3.24.

Let the price of the fifth item be x, then according to the question;

[tex]\dfrac{ 4.55+ 2.53+2.82+4.66+x}{5} = 3.24\\14.65 + x = 3.24 \times 5\\14.65 + x = 16.2\\x = 1.55[/tex]

Therefore, the price of the fifth item in the bag is $1.55.

Answer:

P = 5x - 10

Step-by-step explanation:

The perimeter is:

P = L + w

L = 3x - 2

w = 2x - 8

P = 3x -2 + 2x - 8

P = 5x - 10

To know the exact value we need to know the value of x or the solve of one of the expressions above.

Step-by-step explanation:

A man purchase 5 dozen banana , find equation to find total number of banana and how many banana he have.

Total number of banana = 12 x 6

Total number of banana = 60

The total surface area of the figure is 862ft²

The composite figure is made up of a pyramid and prism

Surface area of pyramid = 2(13*9) + (10*9) + (10*12)
Surface area of pyramid = 234 + 90 +120

Surface area of pyramid = 444ft²

For the rectangular prism

Surface area  = 2(11*9) + 2(10 * 11)

Surface area = 198 + 220
Surface area = 418ft²

Surface area of figure = 444 + 418

Surface area of figure = 862ft²

Hence the total surface area of the figure is 862ft²

Answer:

C. y = 1/8x

D. y = x - 133

Step-by-step explanation:

In order to find the answer, you have to think about the answer choices

A. is saying that if you multiply 152 by 8, you will get 19 which is definitely not true

B. is saying that y is equal to 152/133 which is not true since 152/133= 8/7 which is some wacky decimal

C. would make sense because if you divide 152 and 8, you will get 19

Which makes the equation true because if you multiply 1/8 by 152/1, you get 152/8 which simplifies to 19 which satisfies the equation

D. This would also make sense since 152-133=19

So at the end, we can come to a conclusion that:

C. and D. are the equations that satisfy the relation

Answer:  3

Step-by-step explanation:

Let x be the missing base. In this case, base to the power of 2 means this number x times itself will equal 9.

9 = [tex]x^{2}[/tex]

[tex]\sqrt{9}[/tex] = [tex]\sqrt{x^{2} }[/tex]  [use square root to cancel the power of 2].

[tex]\sqrt{9}[/tex] = x

x = 3

Check: [tex]3^{2}[/tex] = 3 x 3 = 9

The product of the slopes of this line and the line perpendicular to it is equal to -1.

Note that the slope if the coefficient of x.

Let

[tex] \alpha [/tex]

be the slope of the given line.

Let

[tex] \beta [/tex]

be the slope of the line perpendicular to it.

I can therefore say,

[tex] \alpha \times \beta = - 1[/tex]

[tex] \frac{ - 4}{3} \times \beta = - 1[/tex]

[tex] \beta = \frac{ - 1}{ \frac{ - 4}{3} } [/tex]

[tex] \beta = \frac{ - 3}{ - 4} = \frac{3}{ 4} [/tex]

The slope is 3/4

The factor of the polynomial [tex]f(x) = 6x^4 - 21x^3 - 4x^2 + 24x - 35[/tex] is (a) 2x - 7

The polynomial function is given as:

[tex]f(x) = 6x^4 - 21x^3 - 4x^2 + 24x - 35[/tex]

To determine if 2x - 7 is a factor, we start by setting it to 0

[tex]2x - 7 = 0[/tex]

Add 7 to both sides

[tex]2x = 7[/tex]

Divide both sides by 2

[tex]x =3.5[/tex]

Substitute 3.5 for x in f(x)

[tex]f(3.5) = 6(3.5)^4 - 21(3.5)^3 - 4(3.5)^2 + 24(3.5) - 35[/tex]

[tex]f(3.5) =0[/tex]

Because f(3.5) equals 0, then 2x - 7 is a factor of the polynomial
