Answer:

$9.12

Step-by-step explanation:

Decimal places are:

0.0 --> Tenths

0.00 --> Hundredths

0.000 --> Thousandths

etc.

Therefore we need to round the decimal to 2 decimal places...

9.123 --> 9.12 (The number rounds down if the number after it is between 1 and 4 and it rounds up if the number after it is between 5 and 9. In this scenario the number after it is "3" therefore it rounds down)

sp2606 [1]

Answer:

score 35 is not possible

Step-by-step explanation:

Here, the competitor misses exactly two shots

what we have here is that, if we added from the numbers between 1-10 , excluding exactly two numbers, which of the numbers in the option cannot be obtained by this addition

a) 52

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10

Total is 55

if we removed (2 and 1)

we get 52

This is a possible score

b) 44

Here, we just have to remove 11

if we take off 10 and 1, we can have 44

c) 41

if we removed 4 and 10 ; we get 41

d) 38

if we remove 17, we get 38

so let us remove 10 and 7

e) 35

here, we have to remove 20

Now, no two numbers added between 1 and 10 exactly will give 20

The highest sum to be deducted is 9 + 10 which is 19

So the lowest possible score is 55-19 = 36

This means that the term 35 is not possible

Given the function:

anyanavicka [17]

You are correct. The answer is choice D

The only way for g(x) to be differentiable at x = 0 is for two things to happen
(1) g(x) is continuous at x = 0
(2) g ' (x) is continuous at x = 0

To satisfy property (1) above, the value of b must be 1. This can be found by plugging x = 0 into each piece of the piecewise function and solving for b.

So the piecewise function becomes
$g(x) = \begin{cases}x+1 \ \text{ if } \ x \ < \ 0\\ \cos(x) \text{ if } \ x \ge 0\end{cases}$
after plugging in b = 1

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

Now differentiate each piece with respect to x to get
$g'(x) = \begin{cases}1 \ \text{ if } \ x \ < \ 0\\ -\sin(x) \text{ if } \ x \ge 0\end{cases}$
The first piece of g ' (x) is always going to be equal to 1. The second piece is equal to zero when x = 0
Because -sin(x) = -sin(0) = 0

So there's this disconnect on g ' (x) meaning its not continuous

Therefore, the value b = 1 will not work.

So there are no values of b that work to satisfy property (1) and property (2) mentioned at the top.

8% of 70 is what number? (please explain)

Bingel [31]

Do a proportion
8/100= x/70
Cross multiply and divide
70 x 8= 560
560 divided by 100= 5.6
Answer is 5.6

You also could have done .08 x 70 which is also 5.6
