Answer:

see below

Step-by-step explanation:

all formulas of exponent given by:

\displaystyle {x}^{1}  = x  \stackrel{ \rm example}{ \iff} 2^{1}  = 2

\displaystyle{x}^{0}  = 1\stackrel{ \rm example}{ \iff} 2^{0}  = 1

\rm \displaystyle {x}^{m} \cdot  { x }^{n}   =  {x}^{m + n}  \stackrel{ \rm example}{ \iff} x^{1 } \cdot  {x}^{2}   = x^{1 + 2 } =  {x}^{3}

\displaystyle \sqrt[n]{{x} }= x^{1/n} \stackrel{ \rm example}{ \iff} \sqrt[3]{x}  = x^{1/3}

\rm \displaystyle  \frac{{x}^{m}  }{ { x }^{n}}   =  {x}^{m  - n}  \stackrel{ \rm example}{ \iff}  \frac{x^{3} }{ {x}^{1}  } = x^{3  -  1} =  {x}^{2}

\rm \displaystyle ({x}^{m} {)}^{n} =  {x}^{m n}  \stackrel{ \rm example}{ \iff} (x^{1 } {)}^{2}  = x^{ 2 }

\rm \displaystyle ({x}^{m} {y}^{m}  {)}^{n} =  {x}^{m n}  {y}^{mn}  \stackrel{ \rm example}{ \iff} (x^{1 } { {y}^{1} )}^{2}  = x^{ 2 }  {y}^{2}

\rm \displaystyle   \left(\frac{{x}^{}  }{ { y }^{}}  \right) ^{m}   =  \frac{{x}^{m}  }{ { y }^{n} } ^{}    \stackrel{ \rm example}{ \iff}   =   \left(\frac{ {x}^{2} }{ {y}^{2} }  \right)^{2}  = \frac{ {x}^{4} }{ {y}^{4} }

\displaystyle {x}^{ - n}  =  \frac{1}{ {x}^{n} }  \stackrel{ \rm example}{ \iff} x^{ - 2}  =  \frac{1}{ {x}^{2} }

Answer:

The conclusion "T" logically follows from the premises given and the argument is valid

Step-by-step explanation:

Let us use notations to represent the steps

P: I take a bus

Q: I take the subway

R: I will be late for my appointment

S: I take a taxi

T: I will be broke

The given statement in symbolic form can be written as,

(P V Q) → R

S → (¬R ∧ T)

(¬Q ∧ ¬P) → S

¬R

___________________

∴ T

PROOF:

1. (¬Q ∧ ¬P) → S                Premise

2. S → (¬R ∧ T)                  Premise

3. (¬Q ∧ ¬P) → (¬R ∧ T)    (1), (2), Chain Rule

4. ¬(P ∨ Q) → (¬R ∧ T)      (3), DeMorgan's law

5. (P ∨ Q) → R                   Premise

6. ¬R                                 Premise

7. ¬(P ∨ Q)                        (5), (6), Modus Tollen's rule

8. ¬R ∧ T                          (4), (7), Modus Ponen's rule

9. T                                   (8), Rule of Conjunction

Therefore the conclusion "T" logically follows from the given premises and the argument is valid.

Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.
Aloiza [94]

Answer:

0.70275

Step-by-step explanation:

Data provided in the question:

4e²ˣ⁻¹ -1 = 5

now solving for 'x'

⇒ 4e²ˣ⁻¹ = 5 + 1

or

⇒ 4e²ˣ⁻¹ = 6

or

⇒ e^{(2x-1)} =\frac{6}{4}

or

⇒ e^{(2x-1)} =\frac{3}{2}

now,

taking natural log both sides, we get

⇒ 2x - 1 = \ln(\frac{3}{2})

also,

we know

⇒ \log(\frac{A}{B}) = \log(A)+\log(B)

thus,

⇒ 2x - 1 = ln(3) - ln(2)

or

⇒ 2x - 1 = 1.0986 - 0.6931

or

⇒ 2x - 1 = 0.4055

or

⇒ 2x = 0.4055 + 1

or

⇒ 2x = 1.4055

or

⇒ x = 0.70275

Find the value of x. x, 50, and 70
Rama09 [41]
X = 60°

To work this out, you would do 50°+70° to get 120°. You would then subtract this from 180° (the total for any triangle) to get the final answer of 60°.

Pls help me this is so hard
Mama L [17]

Answer:

She is not breaking even. The discounted price is .84t, which is less than t.

Step-by-step explanation:

Retail price= 1.4

1.4×.4= .56

40% of 1.4 is .56

Subtract 40% of 1.4 from the retail price because she is marking down.

(1.4)-(.56)=.84

So the discounted price is .84t

This problem is difficult because we don't know if she sold any tea by the retail price and if she did how much did she sell.
