Answer:

\sf2 \cdot \cfrac{7(3 {}^{2}) }{3}  = \boxed{ \bf 42}

Step-by-step explanation:

Given expression:

\sf2 \cdot \cfrac{7(3 {}^{2}) }{3}

To :

  • Evaluate the expression.

Solution:

Let's use PEMDAS for evaluating.

  • P stands for Parentheses
  • E for exponents
  • M for multiplication
  • D for Division
  • A for addition
  • S for subtraction

\sf2 \cdot \cfrac{7(3 {}^{2}) }{3}

\rightarrow 2 \times  \cfrac{7(9)}{3}

\rightarrow \: 2 \times  \cfrac{63}{3}

\rightarrow \:  \cfrac{2 \times  \cancel{63}  \:  \: {}^{21} }{ \cancel3 \:  \:  {}^{1} }

\rightarrow2 \times 21

\longrightarrow \sf \: 42

<u>Hence we can conclude:</u>

\sf2 \cdot \cfrac{7(3 {}^{2}) }{3}  = \boxed{ \bf 42}

Answer:

42

Step-by-step explanation:

We use (BODMAS) :

Brackets

Order/Index

Division

Multiplication

Addition

Subtraction

Now we do bracket first :

7(3²) = 7(9) = 63

Now we do division :

63÷3 = 21

Now we do multiplication :

2 × 21 = 42

Hope this helped and have a good day

18.There is no battery in this simulation. Move the magnet with the N pole toward the loops (coils) connected to the light bulb
astraxan [27]

Answer:

Step-by-step explanation:

Whenever a magnetic field linked to loop changes, the current is induced in the loop which sequentially opposes the cause of change in magnetic flux. So whenever the magnet moves towards and away from the loop then it causes the current to induce in the loop to oppose the change in magnetic flux by effectively creating a similar pole that is coming towards the loop.

For example, if the magnet north pole is coming towards loops then it effectively creates a north pole in front of the magnet.

So flow of current will glow the light bulb.

Determine, using the intermediate value theorem, if the function F(x)=x^3+2x-1 has a zero on the interval [0,1]. Justify your an
SSSSS [86.1K]

Plug x = 0 into the function

f(x) = x^3 + 2x - 1

f(0) = 0^3 + 2(0) - 1

f(0) = -1

Note how the result is negative. The actual number itself doesn't matter. All we care about is the sign of the result.

Repeat for x = 1

f(x) = x^3 + 2x - 1

f(1) = 1^3 + 2(1) - 1

f(1) = 2

This result is positive.

---------------------------

We found that f(0) = -1 and f(1) = 2. The first output -1 is negative while the second output 2 is positive. Going from negative to positive means that, at some point, we will hit y = 0. We might have multiple instances of this happening, or just one. We don't know for sure. The only thing we do know is that there is at least one root in this interval.

To actually find this root, you'll need to use a graphing calculator because the root is some complicated decimal value. Using a graphing calculator, you should find the root to be approximately 0.4533976515
