You have a new 10-day workout routine. You want to do 10 sets of 10 sit-ups each
Sholpan [36]

Answer:

10²

Step-by-step explanation:

Another way of phrasing "10 sets of 10 sit-ups" is "10 sit-ups, 10 times," or mathematically, 10 x 10. Another way of writing repeated multiplication is through <em>exponents</em>. Since we have 2 10's multiplied together, we can rewrite our expression as 10².

For the function f(x) = 6x − 8, identify the values of f(0), f(1/2), and f(−2).
Anuta_ua [19.1K]

Answer:

[see below]

Step-by-step explanation:

Replace 'x' with the given value and evaluate.

For f(0):

f(0)=6x-8\\\\f(0)=6(0)-8\\\\f(0)=0-8\\\\\boxed{f(0)=-8}

For f(1/2):

f(1/2)=6(1/2)-8\\\\f(1/2)=3-8\\\\\boxed{f(1/2)=-5}

For f(-2):

f(-2)=6(-2)-8\\\\f(-2)=-12-8\\\\\boxed{f(-2)=-20}

Hope this helps.

Vitek1552 [10]

$3.20 I think

Step-by-step explanation:

9.60 divided by 3 is 3.2. 3.2 multiplied by 3 is 9.6. That's why I think it's $3.20.

Check the picture below.

so... if Julia folded the paper, in a way that P was on top of Q, that means the crease is running through the half-way point or midpoint, that means that, if the segment PQ is 2.4, the segments on either side of the crease, PS and QS are both two equal halves.
