If I fall for 18 s what would my final velocity be, if I started from rest.

Answers

Answer:

176.58 m/s

Step-by-step explanation:

assume that the acceleration due to gravity, g = 9.81 m/s²

I also assume we neglect air resistance (hence we assume no terminal velocity)

recall that one of the equations of motions can be expressed as

v = u + at, where

u = initial velocity = 0 (because it says you started from rest)

v = final velocity (we are asked to find this)

a = acceleration due to gravity = 9.81 m/s²

t = time = given as 18s

simply substitute the above into the equation.

v = 0 + (9.81)(18)

v = 176.58 m/s

m∠2 = m∠3 [tex]{}[/tex]                                                Identity property

∠2 ≅ ∠3 [tex]{}[/tex]                                      [tex]{}[/tex]               Equal angles are congruent

Step-by-step explanation:

Given [tex]{}[/tex]                                                                            Reason

∠1 and ∠2 are supplementary    [tex]{}[/tex]             Given

Therefore;

m∠1 + m∠2 = 180°                              [tex]{}[/tex]       Supplementary ∠s sum up to 180°

∠3 and ∠4 are supplementary    [tex]{}[/tex]             Given

Therefore;

m∠3 + m∠4 = 180°                              [tex]{}[/tex]       Supplementary ∠s sum up to 180°

From which we have;

m∠1 + m∠2 = 180° = m∠3 + m∠4       [tex]{}[/tex]   [tex]{}[/tex]    Transitive property

m∠1 + m∠2 = m∠3 + m∠4

∠1 ≅ ∠4                          [tex]{}[/tex]                             Given

m∠1 = m∠4                                    [tex]{}[/tex]              Congruent ∠s have equal measure

Therefore;

m∠1 + m∠2 = m∠3 + m∠1              [tex]{}[/tex]         [tex]{}[/tex]   Transitive property

Therefore;

m∠1 + m∠2 - m∠1= m∠3 + m∠1 - m∠1       [tex]{}[/tex]Subtraction property

how many pennies fit in a 22-inch circle?​

Answers

Answer :

663 Pennies can fit into a 22-inch circle

The required number of pennies fit in the circle is 13.

Area of the Circle:

The formula of the area of the circle is [tex]A=\pi r^2[/tex]

As we know that the standard radius of a penny is 0.75 inch

So, the area of the one penny is,

[tex]A=\pi r^2\\A=3.14\times (0.75)^2\\A=1.77[/tex]

So, the total number of pennies fit in the 22-inch circle is,

A nurse mixes 50 cc of a 60% saline solution with a 10% saline solution to produce a 20% saline solution. How much of the 10% solution should he use?

Answers

Answer:

The nurse should use 200cc of the 10% saline solution in order to produce a 20% saline solution.

Step-by-step explanation:

to the given mix we add a quantity of a lower mix to generate another.

50cc at 60% + Xcc at 10% = (50 + X)cc at 20%

50 x 60% + X x 10% = (50 + X) x 20%

30 + 0.1X = 10 + 0.2X

30 - 10 = 0.2X - 0.1X

20 = 0.1X

20/0.1 = X

X = 200

Answer:

The expression for new cost is 3(3.50/2 + 1.35)

What is equations?

A mathematical statement that consists of two expressions connected by an equal sign is called an equation.

Given the cost of popcorn is half when movie is half over,

according to question

original cost of popcorn = 3.50

cost at interval = 3.50/2

cost of drink = 1.35

cost of 3 drink = 3 x 1.35

cost of 3 popcorn = 3 x 3.50/2

expression for new cost for 3 orders of popcorn and 3 drinks

3 x 3.50/2 + 3 x 1.35

= 3(3.50/2 + 1.35)

Hence the expression is 3(3.50/2 + 1.35)

What type of move takes Figure A to Figure B?*

Answers

Answer: Rotation

Step-by-step explanation:

From the figure , we can observe that both figure A and b are absolutely congruent.

To translate a figure to make congruent images , we use rigid motions (Translation, Reflection, Rotation)

It is Rotation because of we move Figure A 180 degrees clockwise about the fixed point O, we will get Figure B .

It cannot be reflection because both figures are not mirror images.

It cannot be translation because all points on Figure A is not moving , as point O remained at same position throughout this which is not possible in translation.

I have the correct answer, I just don't know how to get to it.
answer is: [tex]f^{-1} =\frac{-2-3x}{3x-1}[/tex]

Answers

Step-by-step explanation:

f(x) = (x-2)/(3x+3). Let y = f(x).

Then y = (x-2)/(3x+3).

y(3x+3) = x - 2

3xy + 3y = x - 2

3xy - x = -3y - 2

x(3y-1) = -(3y+2)

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

Hence, the inverse of f(x) is -(3x+2)/(3x-1).

3(b + 3) - 4(-2+b) = 19

Answers

Answer:

b= -2

Step-by-step explanation:

Answer:

b = -2

Step-by-step explanation:

The first thing we need to do to solve this equation is expand the brackets. To so this we need to multiply the outside term with each of the terms inside the bracket (distributive law).

This gives us:

3xb + 3x3 -4x-2 -4xb = 19

Which multiplies out to:

3b + 9 + 8 -4b = 19

Combine like terms:

-b +17 = 19

From here we move the 17 to the other side by subtracting 17 from both sides

-b +17 -17 = 19 - 17

-b = 2

Divide both sides by -1:

-b/-1 = 2/-1

Which gives us:

b = -2

Step-by-step explanation:

Answer: It is a polynomial, and the degree is 5.

I could be wrong on this but, i'm trying

Step-by-step explanation:

Polynomials in one variable are algebraic expressions that consist of terms in the form axn a x n where n is a non-negative (i.e. positive or zero) integer and a is a real number and is called the coefficient of the term. The degree of a polynomial in one variable is the largest exponent in the polynomial. Also, all exponents have to be positive in a polynomial. Another rule of thumb is if there are any variables in the denominator of a fraction then the algebraic expression isn’t a polynomial.Note that this doesn’t mean that radicals and fractions aren’t allowed in polynomials. They just can’t involve the variables.

The degree is 5 (since the largest exponent is 5)

Examples of Non- Polynomials

3x^½ +2 Not a polynomial because a term has a fraction exponent
