Answer:

-384

Step-by-step explanation:

geometric sequence : every new element is generated by multiplying the previous element always with the same number r.

a(n) = a(n-1) * r

a(n) = a(1) * r^(n-1)

so, a(1) = 3, r = -2

a(8) = ?

a(8) = a(1) * r^7 = 3 * (-2)^7

a negative number to an uneven power is again a negative number.

so, (-2)^7 = -128

3 * -128 = -384 = a(8)

Answer:

k = -3

Step-by-step explanation:

f(x) = -2x+1

g(x) = 6x - 3

=> g(x) = k.f(x)

6x - 3 = k(-2x+1)

k = (6x-3)/(-2x+1)

= 3(2x-1)/-1(2x-1)

k = 3/(-1) = -3

The value of k for the given function will be k = -3.

In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. A function can be thought of as a machine that takes an input, performs a certain operation on it, and produces an output.

Formally, a function is defined as a set of ordered pairs (x, y) such that each value of x is associated with exactly one value of y. The set of all possible inputs to a function is called its domain, while the set of all possible outputs is called its range.

The given functions are,

f(x) = -2x+1

g(x) = 6x - 3

The value of k will be calculated as,

g(x) = k.f(x)

6x - 3 = k(-2x+1)

k = (6x-3)/(-2x+1)

k= 3(2x-1)/-1(2x-1)

k = 3/(-1) = -3

The above expression can be rewritten as

log(10) x^5 + log(10) 20 - log(10) 10

= log(10) [(20x^5)/10]

= log(10) (2x^5)

Answer:

Solution given:

equation of line j is:

y=2x+8

comparing above equation with y=mx+c

we get

m=2

let slope of another line k be M

since lines are perpendicular

their product is -1

so

m *M=-1

2M=-1

M=-½

since it passes from (6,-6)

we have

(y-y1)=M(x-x1)

(y+6)=-½(x-6)

2y+12=-x+6

x+2y+12-6=0

x+2y+6=0 is a required equation of line k.

Answer:

[tex] \displaystyle y = - \frac{1}{2} x - 3[/tex]

Step-by-step explanation:

we are given that,

[tex] \displaystyle E _{ j}: y = 2x + 8[/tex]

and it's perpendicular to [tex]E_k[/tex]

since [tex]E_k[/tex] is perpendicular to [tex]E_j[/tex] the slope of the equation of k has to be -½

because we know that

[tex] \displaystyle m_{ \text{perpendicular}} = - \frac{1}{m}[/tex]

we are also given a point where the perpendicular line passes as we got the slope and a point we can consider using point-slope form of linear equation to figure out the perpendicular line

remember the point slope form

[tex] \displaystyle y - y_{1} = m(x - x_{1})[/tex]

we got that, y1=-6,x1=6 and m=-½ thus,

substitute:

[tex] \displaystyle y - ( - 6)= - \frac{1}{2} (x - 6)[/tex]

remove parentheses:

[tex] \displaystyle y + 6= - \frac{1}{2} (x - 6)[/tex]

distribute:

[tex] \displaystyle y + 6= - \frac{1}{2} x + 3[/tex]

cancel 6 from both sides:

[tex] \displaystyle y = - \frac{1}{2} x - 3[/tex]

hence, the equation of line k is y=-½x-3

Answer:

1,440 cubic centimeter = 1,440 milliliters

1,440 cubic centimeter= 1.44 liters

Step-by-step explanation:

Volume of the rectangular tank = length × width × height

Length = 16 cm

Width = 9 cm

Height = 10 cm

Volume of the rectangular tank = length × width × height

= 16 cm × 9 cm × 10 cm

= 1,440 cm³

Volume of the rectangular tank = 1,440 cm³

How many milliliters of water are in the tank when it is full?

1 cubic centimeter = 1 milliliter

1,440 cubic centimeter = 1,440 milliliters

How many liters?

1 cubic centimeter = 0.001 liters

1,440 cubic centimeter= 1.44 liters

Answer:

200 ml of fertilizer

Step-by-step explanation:

Create a proportion where x is the amount of fertilizer needed for an area of 40 m²

[tex]\frac{180}{36}[/tex] = [tex]\frac{x}{40}[/tex]

Cross multiply and solve for x:

36x = 7200

x = 200

So, 200 ml of fertilizer is needed

Answer:

an = -6n + 5.

Step-by-step explanation:

This is an arithmetic sequence with first term a1 = -1 and common difference d = -6

an = a1 + d(n-1)

an = -1 + -6(n - 1)

an = -1 -6n + 6

an = -6n + 5.

Answer:

95 students

Step-by-step explanation:

25 students -- 19 have sibling

1 student -- (19/25)

125 students -- (19/25) * 125 = 95

Therefore, 95 students out of 125 are expected to have at least one sibling.

Thenks and mark me brainliest :))

Answer:

95

Step-by-step explanation:

Calculate the experimental probability of choosing a student who has at least one sibling:  It is 19/25, or 0.56.

If 125 students are selected, this probability applies.  Multiply 125 by 0.56:

0.56(125 students) = 95

95 students could be expected to report having at least one sibling.

Answer:

x = 2

UV = 9 ft

VW = 6 ft

WU = 5 ft

Step-by-step explanation:

The perimeter of a figure can be represented as the sum of lengths of all of its sides. In this case we can write:

P = UV + VW + WU

Now, we can substitute the values which we have:

20 = 4x + 1 + 8 - x + 2x + 1

We can combine like terms...

20 = 5x + 10

5x = 10

x = 2

Since UV is represented by 4x + 1, we can substitute in x to find its length.

UV = 4x + 1

UV = 4(2) + 1

UV = 6 + 1

UV = 9

We can do the same for the other two sides:

VW = 8 - x

VW = 8 - 2

VW = 6

WU = 2x + 1

WU = 2(2) + 1

WU = 4 + 1

WU = 5

144=a²+81

a²=144-81

a²=63

a=√63

a=7.94

Answer:

x + 2y = -8 = y = -4 - 1/2x

y= -1/2x + 4 =  y = 4

y= -1/2x - 4 = y = -4

y=-2x - 4 = y = -4

y=1/2x-4 = y = -4

Step-by-step explanation:

(x + 2y = -8 = y = -4 - 1/2x)

[tex]x+2y=-8\\2y=-8-x\\y=-4-\frac{1}{2}x\\[/tex]
