Start with

4(3^3-8) \div 2

Exponents have the highest priority, so we evaluate 3 cubed first:

4(27-8) \div 2

Next, we have to solve parenthesis first: we have 27-8 = 19, so the expression becomes

4 \times 19 \div 2

Multiplications and divisions have the same priority, so we perform them as they appear: 4 \times 19 = 76, so the expression becomes

76 \div 2 = 38

Which point lies on the graph of the function shown below?
horsena [70]

Answer:

(1, 1)

Step-by-step explanation:

We need to evaluate the given expression for each of the x-values and check if the y-value agrees with the y-value given in the pairs:

1) First point (-1,3): use x=-1 and check if y results in "3":

y=-x^2+4x-2\\y=-(-1)^2+4(-1)-2\\y=-1-4-2=-7

we obtained y=-7, so the point (-1,3) is Not on the graph of the function

2) Second point (0,2): use x=0 and check if y results in "2":

y=-x^2+4x-2\\y=-(0)^2+4(0)-2\\y=-0+0-2=-2

we obtained y=-2, so the point (0,2) is Not on the graph of the function

3) Third point (2,-2): use x=2 and check if y results in "-2":

y=-x^2+4x-2\\y=-(2)^2+4(2)-2\\y=-4+8-2=2

we obtained y=2 (and not -2), so the point (2,-2) is Not on the graph of the function

4) Fourth point (1,1): use x=1 and check if y results in "1":

y=-x^2+4x-2\\y=-(1)^2+4(1)-2\\y=-1+4-2=1

we obtained y=1 (the same y as in the given coordinate pair), so the point (1,1) IS on the graph of the function

Dave bought some fresh produce. He picked up 2 oranges, and 3 bananas. The cost of the Dave's shopping was $9.16.
Helga [31]

Answer:prices = {"banana": 4, "apple": 2, "orange": 1.5, "pear": 3}

stock = {"banana": 6, "apple": 0, "orange": 32, "pear": 15}

for item in prices:

   print item + ":"

   print "price: " + str(prices[item])

   print "stock: " + str(stock[item])

Step-by-step explanation:

prices = {"banana": 4, "apple": 2, "orange": 1.5, "pear": 3}

stock = {"banana": 6, "apple": 0, "orange": 32, "pear": 15}

for item in prices:

   print item + ":"

   print "price: " + str(prices[item])

   print "stock: " + str(stock[item])

Sarah, Amy and Liam stand on some weighing scales two at a time.
ahrayia [7]
So here is how to solve the problem.
Let us analyze it first.
S + A = 70
S + L = 80
L + A = 80
Since S + L is equal to L + A, this would mean that S = A.
So S + A = 70 So A = 70/2 = 35kg
And lastly L. L= 80 -35 = 45kgs.
Therefore, Liam's weight is 45kgs.
Hope this explanation helps.
Let me know if you need more help next time. Have a great day!

B. What are the second and third terms of this arithmetic sequence? 80, 페, 페, 125,...........
nataly862011 [7]

The 2nd and 3rd term of an AP is found to be (a₂ = 95) and (a₃ = 110).

<h3>What is the sequence of AP arithmetic progression?</h3>

In Arithmetic Progression, the difference between the two numerical orders is a fixed number (AP). Arithmetic Sequence is another name for it.

We'd come across a few key concepts in AP that had been labeled as:

  • The first term (a)
  • Common difference (d)
  • Term nth (an)
  • The total of first n terms (Sn)

As shown below, the AP can also be referred to in terms of common differences.

  • The following is the procedure for evaluating an AP's n-th term:  an = a + (n − 1) × d
  • The arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].
  • Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ......      = an - an-1.

Now, the given sequence is; 80, _, _, 125.

The series comprises of four given terms.

Let the first term be 'a₁' = 180.

The second term be 'a₂'.

The third term be 'a₃'.

And, the fourth term is 'a₄' = 125.

Use the nth term formula to find the common difference 'd'.

n-th term:  an = a + (n − 1) × d

a₄ = a + (n - 1)d

125 = 80 + (4 - 1)d

45 = 3d

d = 15

Thus, the common difference is 15.

The second term is calculated as;

a₂ = a₁ + d

a₂ = 80 + 15

a₂ = 95.

The third term is estimated as;

a₃ = a₂ + d

a₃ = 95 = 15

a₃ = 110

Therefore, the 2nd and third term of an AP is computed as 95 and 110.
