Answer:

n = 2

Step-by-step explanation:

divide by 7 on both sides

Answer:

n = 2

Step-by-step explanation:

7n is the same as 7 times value = 14.

You may find the value of n by simply dividing both sides by seven, in order to isolate the variable.

^ 14/7 = 7n/7

^ (simplified) 2 = n or n =2

Therefore:

Your answer is 2 or n's value in this scenario is 2.

Let the original water level is x.

Use below equation to find its value:

Answer:

C

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{285}{360}[/tex]

    = 2π × 18 × [tex]\frac{19}{24}[/tex]

    = 36π × [tex]\frac{19}{24}[/tex] ( cancel 36 and 24 by 12 )

    = 3π × [tex]\frac{19}{2}[/tex]

    = [tex]\frac{57\pi }{2}[/tex] → C

Answer:

-6

Step-by-step explanation:

Plug in -1/3for t

W(-1/3)=15(-1/3)-1=-5-1=-6

Answer:

-6

Step-by-step explanation:

substitute -1/3 into w(t) = 15t - 1

=>  w(-1/3) = 15(-1/3) - 1

=> w(-1/3) = -6

Answer:

  x ∈ {-1/2, 1, 2-√3, 2+√3}

Step-by-step explanation:

The given zeros mean that one of the quadratic factors of the given polynomial is ...

  (x -2)^ -3 = x^2 -4x +1

When that is factored out (see first attachment), the remaining quadratic is ...

  2x^2 -x -1

This can be factored as ...

  = (2x +1)(x -1)

which has roots that make these factors zero: x = -1/2, x = 1.

So, all of the zeros of the given polynomial are ...

  -1/2, 1, 2-√3, 2+√3 . . . all zeros

__

A graphing calculator can often point to the zeros of the function quite nicely.

_____

Additional comments

When p is a zero of a polynomial, (x-p) is a factor of it. The given zeros mean that factors are (x-2-√3) and (x-2+√3). The product of these factors is the difference of the squares (x-2)^2 and (√3)^2, so is (x -2)^2 -3.

Using the pattern for the square of a binomial, we see this is ...

  (x-2)^2 = x^2 -2·2x +2^2 = x^2 -4x +4

The product of the given factor is then 3 subtracted from this square. The given zeros mean there is a quadratic factor of ...

  (x-2-√3)(x-2+√3) = (x-2)^2 -3 = x^2 -4x +4 -3 = x^2 -4x +1

Answer:

1/3

Step-by-step explanation:

as 1/6 for a one and 1/6 for a 2 and 1/6 + 1/6 is 2/6 or 1/3

Answer:

The answer is A.

If you look at the x values of the coordinates, you can see that they multiply by 2 when dilated to the next shape.

M (5,0) ---> M' (10,0)   5 to 10 means a scale factor of 2. So A is your answer.

Step-by-step explanation:

simplify

log(x)/log(4) = 0

simplify

log(4x)/log(4) = 1

expand

2log(5)/log(4) + log(4x)/log(4) = log(100)/log(4)

factor

2log(5) + log (4x) / log(4) = log (100) / log (4)

then

x=1

Step-by-step explanation:

let the ratio of ice cream be x&4x

total number of ice cream =30

now,

x+4x=30

5x=30

x=30/5

x=6

mango ice cream=x=6

strawberry ice cream=4x=4×6=24

hope it helps.

Answer:

6 !

Step-by-step explanation:

mango = x

strwberry = 4x

total = x+4x = 5x = 30

5x= 30

x= 30/5 = 6

mango = x= 6

strwberry = 4x = 24

I hope im right!

Answer:

3.88

Step-by-step explanation:

Given that

42x = 163

It set 2x = 3

and x = 32

We need to tell the mistake and mentioned the correct answer

if we solve the above equation i.e.

42x = 163

x = 3.88

Hence, in this way it should be calculated

The same would be considered and relevant

Hence, the correct answer is 3.88

V=4/3π4^3

V=268.08257

6) r=1/2d

r=1/2(13)

r=6.5

V= 4/3πr^3

V= 4/3π 6.5^3

V=1150.3465

Answer:

Total surface area of this pyramid =665.6 in^2

Answer:

153.94

Step-by-step explanation:

A = (1/4)(196π)

A = 49π

A ≈ 153.94

Answer:

-2 1/4

converting the fraction to decimals

-2 2/5 = -2.4

-2.1 = -2 1/10

-2 1/4 = -2.25

this is between -2.1 and -2.4 on the number line

Step-by-step explanation:

to determine which number is between the numbers specified, convert to fractions

-2 2/5 = -2.4

-2.1 = -2 1/10

-2 1/4 = -2.25

3/10 = -0.3

this is less than -2.1

-21/2 = -2.5

this is greater than -21/4

-15/6 = -1.83

this is less than -2.1

it is only, -21/4 that is between the numbers
