Answer 1
1) 109 Explanation: do what is in the () first so 3^2 is going to turn into 9 which is the equation is now going to be 145-(9x4). 9x4 is 36 so it is 145-36 which gives you 109.
2) 52 Explanation: 45 divided by 9 is 5 then 5 times 12 gives you 60. equation now is 60-8 which equals 52.
3) 4 Explanation: 3 times 4 is 12. equation now is 2^2+12-12. all is left is 2^2 which is 4.
4) 89
5)111
6)72
Answer 2

Answer:

1.  145-(3squared times 4)=109

2. 45 divided by 9 times 12-8= 52

3.  2 squared +3 times 4-12= 4

4.[155-(3 times 9) times 2] -12= 89

5. [(6 times 2) +(5 times 5)  times 3= 111

6. 2 times {15+[24-(1.5 times 2)]}= 72

Step-by-step explanation:

(BOMDAS) brackets, operations, multiplication, division, addition, subtraction

1. (deal with the brackets first)

3 squared=9 then times by 4 =9*4=36

so..

145-36=109

2. (start with division )

45 divided by 9 =5

so

5 times 12-8= 52

3. 2 squared = 4

4 times 3 =12

so

4+12-12 =4

4.  (deal with brackets first)

3 times 9 = 27

27 times 2=  54

155-54= 101

101-12=89

5. (deal with the brackets first)

6 times 2 =12    

5 times 5=25

so 12+25=  37 times 3 = 111

6.  (deal with the brackets first)

1.5 times 2= 3

24-3= 21

15+21=36

2 times 36= 72

hope this helps!!!

A line passes through the points (-100,-9.5•10^3) and (300,3.05•10^4). Find the value of y when x =200. Write answer in scientific notation.Please help asap with details and steps on how to solve.

Answers

Answer:

2.05x10^4

Step-by-step explanation:

The equation of the line is y=100x+500, which can be found through the given points.

So, if x=200, plug that into the equation of the line. y=100(200)+500

y=20000+500

y=20500

In scientific notation, that is 2.05x10^4

Identify the correct weight to the nearest 1/8 pound, then reduce the fraction if possible.

Answers

The correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.

How to convert from decimal to fraction?

For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.

For example:

[tex]0.99 = \dfrac{99}{10^2} = \dfrac{99}{100}[/tex]

(10 raised to power k = 1 followed by k zeroes)

How to add two fractions?

Let we have to add two fractions as:

[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]

Then we will find Lowest Common Multiple (LCM) of  [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.

Once the denominators become same, the numerators can add up directly, giving us the final result of addition.

For this case, we can see from the image that:

Weight shown = 3 pounds + half more pound + half of 1/10 pound more approx. (as the weight hand is approx between 5 and 6 minor ticks after the big 3 pound mark). In each minor mark, one pound is divided in 10 parts, so each minor tick adds up 1/10 of a pound. Half of 1/10 shows that after 5, the hand is not exactly on 6 but sort of in between them, so approximately half.

Thus, weight shown ≈ 3 + 0.5 (half is written 0.5 too) + 1/10 of 0.5 pounds

= 3 + 0.5 + 0.5/10 = 3.5 + 0.05 = 3.55 pounds

Thus, the weight is approx 3.55 pounds.

Converting it to fraction, we get:

[tex]3.55 = \dfrac{355}{100} = \dfrac{5 \times 71}{5 \times 20} = \dfrac{71}{20}[/tex] pounds.

Thus, the correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.

Answers

Answer:

the vertex is at (4, -14)

Step-by-step explanation:

Review "quadratic equations."  These have three terms, and the highest power of x is x^2.  We need to identify the coefficients of the x^2, x and x^0 terms to get info needed to identify the axis of symmetry.

Given f(x) = x^2 - 8x + 2, we see that these coefficients are 1, -8 and 2.

                                                                            b

The formula for the axis of symmetry is x  = - ------

                                                                             2a

which here is x = -(-8)/[2*1], or x = 8/2  or x = 4:  the axis of symmetry.

To find the y-coordinate of the vertex, evaluate the function at x = 4:

f(4) = 4^2 - 8(4) + 2 = 16 - 32 + 2, or f(4) = -14.

Thus, the vertex is at (4, -14).  The graph is that of a parabola that opens up, and the parabola is symmetric about the vertical line x = 4.
