-7 x 7 = -49

We can first figure out 7 x 7, which will be 49. Once we have that, we can look at our negatives. If we have an odd number of negative signs, the answer will be negative. If we have an even number of negative signs, the answer will be positive. In this case, we only have 1 negative sign, and 1 is odd, therefore our answer will be odd.

ANSWER: -49

Hope this helps!

Answer:

function b

Step-by-step explanation:

When its asking for which function has a greater rate of change its asking for which slope has a greater value

the slope is calculated by change in y over change in x

for function a, as y goes up 2 x goes up 1

so the slope ( rate of change) is 2/1

for function b is y goes up 3 x goes up 1

so the slope (rate of change) is 3/1

3/1 is greater than 2/1 so function b has a greater rate of change

A honeybee flaps its wings 200 times per second.how much time is required for one wingbeat? give your answere in millisecond

Fiesta28 [93]

The time required for one wing beat is 5 milliseconds.

<em><u>Explanation</u></em>

Lets assume, the time required for one wing beat is $t$ seconds

So, the time required for 200 wing beat $= 200t$ seconds

Given that, the honeybee flaps its wings 200 times per 1 second. So...

$200t=1 \\ \\ t=\frac{1}{200}seconds\\ \\ t= (\frac{1}{200}*1000 )milliseconds\\ \\ t=( 5 )milliseconds$

So, the time required for one wing beat is 5 milliseconds.
