Answer:

The answer is negative. Answer choice B

Step-by-step explanation:

Here is the question:

-3^40(5.6/2.1)

According to order of operations, we must do -3^40 first.

Its important to note that -3^40 is different than (-3)^40. In the problem you specified, the ^40 only applies to the 3, not -3. So, first we do 3^40 which is a huge number. And then, we need to add a negative symbol to that huge number. So now we have a massive negative number multiplied by 5.6/2.1, which is obviously positive. Obviously, a negative number multiplied by a positive number is still negative. Therfore, the answer is negative.

I hope my answer helped you :)

What is the range of the function y = -x2 + 1?
meriva
<span><span>y = 2 + 2sec(2x) The upper part of the range will be when the secant has the smallest positive value up to infinity. The smallest positive value of the secant is 1 So the minimum of the upper part of the range of y = 2 + 2sec(2x) is 2 + 2(1) = 2 + 2 = 4 So the upper part of the range is [4, ) The lower part of the range will be from negative infinity up to when the secant has the largest negative value. The largest negative value of the secant is -1 So the maximum of the lower part of the range of y = 2 + 2sec(2x) is 2 + 2(-1) = 2 - 2 = 0 So the lower part of the range is (, 0]. Therefore the range is (, 0] U [4, ) </span>

What does the word “flip” tell you to do in “keep change flip” for dividing fractions a) change the place of the numbers numerat
mars1129 [50]

Answer:

b) change the places of the numbers in the numerator and the denominator for the second fraction

Step-by-step explanation:

In the phrase "keep change flip":

You "keep" the first fraction.

"Change" the division sign into a multiplication sign.  

"Flip" (or switch) the places of the numerator and denominator in the second fraction.

Example:

\frac{1}{2} ÷ \frac{1}{3}

\frac{1}{2}*\frac{3}{1}=\frac{3}{2}=1.5

Hope this helps.
