Use the formula v = u + at to find the velocity when

• the initial velocity is 3 m/s
• the acceleration is 1.5 m/s^2
• the time is 7 seconds

Answer:

b = -1

Step-by-step explanation:

5 ^ ( 3b-1) = 5 ^ ( b-3)

since the bases are the same, the exponents are the same

3b-1 = b-3

Subtract b from each side

3b-1-b = b-3-b

2b -1 = -3

Add 1 to each side3

2b-1+1 = -3+1

2b = -2

Divide by 2

2b/2 = -2/2

b =-1

Answer:

b = -1.

Step-by-step explanation:

Since the bases are the same (they are both 5), you can set 3b - 1 equal to b - 3.

3b - 1 = b - 3

3b - b = -3 + 1

2b = -2

b = -1

To make sure you are correct...

5^(3 * -1 - 1) = 5^(-1 - 3)

5^(-3 - 1) = 5^(-4)

5^(-4) = 5^(-4)

Since it matches up, you know that b = -1.

Answer:

the 3rd answer choice is the correct one

Step-by-step explanation:

Let's actually find the inverse function:

1.  Replace 'f(x)' with 'y:'  y = 2x - 10

2. Interchange x and y:  x = 2y - 10

3.  Solve this result for y:  2y = x - 10, or  y =  (1/2)x - 5

Thus, the 3rd answer choice is the correct one.

Is it 0.04?

Step-by-step explanation:

Do tell me if I'm wrong please.

The value of each digit in a number is known as the place value. The number of hundredths that 40 thousandths will have is 4.

The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.

Identification of the place value of a digit in a number:

A thousandth is the (1/1000)th part of something, while a hundredth is the (1/100)th part of something.

Let the number of hundredths be x. Therefore, the number of hundredths can be written as,

40(1/1000) = x(1/100)

0.04 = x/100

x = 4

Hence, the number of hundredths that 40 thousandths will have is 4.

Answer:

23 años

Step-by-step explanation:

Para resolver la situación, consideremos que x es la edad de la persona. Sabemos que dentro de seis años esta tendrá el doble de la edad que tenía hace cuatro años. La edad dentro de 6 años se puede expresar como x+6 y esto será igual al doble de la edad que tenía hace cuatro años, lo que se puede expresar como 2(x-4). De acuerdo a esto:

x+6=2(x-4)

x+6=2x-8

6+8=2x-x

x=14

Ahora que sabemos que la edad de la persona es 14 años, le sumamos 9 y esto da como resultado 23 y esta es la edad que la persona tendrá en 9 años.

Answer:

22

Step-by-step explanation:

The answer is 22. You solve the equation 3x+10=7x-6 like so

3x+10=7x-6

-3     = -3

    10= 4x-6

   +6         +6

     16=4x

      x=4

You then plug in the value of x to the equation for LM.

7x-6 becomes 7*4-6 which is 22.

Answer:

3.44 cm

Step-by-step explanation:

When the pendulum is at its lowest point, the vertical length of the pendulum is L.

When the pendulum is at its highest point, the vertical length of the pendulum is  L cos θ.

So the height difference of the pendulum between its lowest and highest points is h = L − L cos θ.

The pendulum swings 72° from right to left, or 36° from the vertical.

The length of the pendulum is 18 cm.

So the height is:

h = L − L cos θ

h = 18 − 18 cos 36°

h = 3.44

Answer:

First, we find the square of the difference of the z values provided and sum them up giving us a value of 4.997956. We, therefore, calculate the sum of the sample mean given the number of samples to be 5 which gives us zero(0).

To calculate the standard deviation we use the formula that takes the square root of the inverse of the number of samples (n)*(the summation of the square of the difference between the sample and the mean which gives us 1.

*Step-by-step explaination

Given z3= -1.101, (z3 minus mean of z3)^2= 1.212201

Given z4= -0.944, (z4 minus mean of z4)^2=0.891136

Given z9= -0.157, (z9 minus mean of z9)^2= 0.024649

Given z14= 0.629, (z14 minus mean of z14)^2= 0.395641

Given z20= 1.573, (z20 minus mean of z20)^2= 2.474329

Therefore the summation of all Z values = Zero(0)

Also, the summation of (z values minus the mean of z values)^2= 4.997956

Therefore where n =5,

The sample mean of z values is given by the summation of z values divided by n = Zero (0)

To calculate standard deviation we use the formula that takes the square root of the inverse of the number of samples (n)*(the summation of the square of the difference between the sample and the mean which gives us 1.

Using it's concepts, it is found that:

In this problem, the observations are: -1.101, -0.944, -0.157, 0.629 and 1.573.

Hence:

[tex]M = \frac{-1.101 - 0.944 - 0.157 + 0.629 + 1.573}{5} = 0[/tex]

The mean of the z-scores is 0.

[tex]S = \sqrt{\frac{(-1.101-0)^2 + (-0.944-0)^2 + (-0.157-0)^2 + (0.629-0)^2 + (1.573-0)^2}{5}} = 1[/tex]

The standard deviation of the z-scores is 1.

B. p > 12.80(160) + 8235.

Step-by-step explanation:

Since he wants to make a profit, the price he will need to receive for his crop will have to exceed his costs. So, the equation would use the > sign rather than the >= sign.

He harvests crops for $12.80 per acre, with 160 acres. That would be 12.80(160).

He is spending $8235, which adds to the costs of harvesting.

So, the answer will be B. p > 12.80(160) + 8235.

Answer:

[tex]x=-1,\:x=-6[/tex]

Step-by-step explanation:

We can solve this question by applying a quadratic equation, but it would be easier to simply factor the equation. In other words, let's begin by factoring the expression [tex]x^2[/tex] + 7x + 6,

Break this expression down into groups - [tex]\left(x^2+x\right)+\left(6x+6\right)[/tex],

Factor out x from " [tex]\left(x^2+x\right)[/tex] " = [tex]{\quad }x\left(x+1\right)[/tex],

Respectively factor out 6 from " [tex]6x+6\mathrm{}[/tex] " = [tex]6\left(x+1\right)[/tex],

[tex]x\left(x+1\right)+6\left(x+1\right)[/tex] - and now we can group like terms - [tex]\left(x+1\right)\left(x+6\right)[/tex]

Since we have factored this expression, let's make it equivalent to 0, and solve for x. By the Zero Factor Principle we should receive two solutions,

[tex]\left(x+1\right)\left(x+6\right)=0[/tex],

[tex]x+1=0: x=-1[/tex] / [tex]x+6=0: x=-6[/tex],

The solutions to this equation should thus be : [tex]x=-1,\:x=-6[/tex]

Answer:

The answer is A.

Step-by-step explanation:

In order to see if a coordinate is a solution to any equation, you have to substitute the values of x and y into the equation :

[tex] - 3x + 2y = - 21[/tex]

[tex]let \: x = 5 \\ let \: y = - 3[/tex]

[tex] - 3(5) + 2( - 3) = - 15 - 6 = - 21[/tex]

AND

[tex] - x - y = - 2[/tex]

[tex]let \: x = 5 \\ let \: y = - 3[/tex]

[tex] - 5 - ( - 3) = - 5 + 3 = - 2[/tex]

Answer:

{ x : x = 2^n -1 , n ∈ N}

Where N is the set of natural numbers

Step-by-step explanation:

Mathematically, we can rewrite each term in the set as follows;

1 = 2^1 - 1

3 = 2^2 -1

7 = 2^3 -1

15 = 2^4-1

31 = 2^5-1

63 = 2^6 -1

so we can conclude that the nth term is 2^n -1

So writing this in set builder notation, we have;

{ x : x = 2^n -1 , n ∈ N}

Where N is the set of natural numbers
