A 2-column table with 7 rows. The first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2, 3. The sec

ond column is labeled f of x with entries 15, 0, 3, 0, negative 3, 0, 15. Predict which statements are true about the intervals of the continuous function. Check all that apply. f(x) > 0 over the interval (−, 3). f(x) ≤ 0 over the interval [0, 2]. f(x) 0 over the interval (–2, 0). f(x) ≥ 0 over the interval [2, ).

Find the length of the third side. If necessary, write in simplistic radical form.
____ [38]

Answer:

7

Step-by-step explanation:

Just use the Pythagorean Theorem (a^{2}+b^{2}=c^{2})

Let a be the missing side

a^{2}= 8^{2}-\sqrt{15} ^{2}

a^{2}= 64-15

a^{2}= 49

Take the square root of each side

a= \sqrt{49}

a= 7

So the missing side is 7.

Hope this helps! :)

Can some please help me with Algebra 2 work? Its problems 45-48 all and 53-57 just odd numbers
Elanso [62]

45)

E = mc²     <em> (solve for "m" by dividing both sides by c²)</em>

E/c² = m

46)

c(a + b) - d = f  <em>(to solve for "a"; add "d", divide by "c" and then subtract "b")</em>

c(a + b)     = f + d

(a + b)       = (f + d)/c

a              = (f + d)/c  - b

47)

z = πq³h  <em> (solve for "h" by dividing both sides by πq³)</em>

z/πq³ = h

48)

(x + y)/z - a = b   <em> (solve for "y"; add "a", multiply by "z", and then subtract "x")</em>

(x + y)/z      = b + a

(x + y)         = z(b + a)

     y           = z(b + a) - x

53)

5x - 9 = 11x + 3

     -9 = 6x + 3      <em>subtracted 5x from both sides</em>

    -12 = 6x          <em>subtracted 3 from both sides</em>

      -2 = x           <em>divided both sides by 6</em>

55)

5.4(3k - 12)   +   3.2(2k + 6) = -136

16.2k - 64.8   +  6.4k + 19.2 = -136      <em>distributed 5.4 and 3.2</em>

22.6k - 45.6 = -136             <em>added like terms (16.2k + 6.4k and -64.8 + 19.2</em>

22.6k = -90.4                    <em>added 45.6 to both sides</em>

      k = -4                       <em>divided both sides by 22.6</em>

57)

(4/9)y + 5 = (-7/9)y - 8

4y + 45 = -7y - 72           <em>multiplied by 9 to clear the denominator</em>

11y + 45 = -72                 <em>added 7y to both sides</em>

11y         = -99                  <em>subtracted 45 from both sides</em>

y            = -9                    <em>divided both sides by 11</em>

Aubree practices the piano 1197 minutes in 3 weeks. At what rate did she practice, in minutes per day?
Norma-Jean [14]

Answer:

57

Step-by-step explanation:

We need to create a ratio. so Aubree practices the piano for 1197 min: in 3 weeks. So for 1 week, we have to divide 1197 by 3, so 1197/=399. And so we know that 1 week is 7 days, just divide 399 by 7! 399/7=57. The rate that she practiced per day is 57 minutes. So one last final step just to check if this answer is correct is to divide 57 by 60, and that is 0.95. 0.95 out of 1.00 minutes per day is 95/100. Cross multiply with x/60, and you will get your answer, which is 57.

raketka [301]

Answer:

0

Step-by-step explanation:

19z-19z=0

this is because z is always equivalent to itself, and therefore 19z is equivalent to 19z

When you subtract two numbers that are equivalent, you will always get 0
