Answer:

To justify a solution, students will need to be able to use appropriate mathematical language to give reasons for the particular approach used to solve a problem. Any time that a student produces a 'solution' in an attempt to solve a problem, that 'solution' needs to be justified.

If a+b=5 and a-b=4 then b^2-a^2 =
Anna007 [38]

Answer:

a + b = 5 \\ a \:  = 5 - b \\  a - b = 4 \\ 5 - b - b = 4 \\ 5 - 2b = 4 \\ 5 - 4 = 2b \\ 1 = 2b \\  \frac{1}{2}  =  \frac{2b}{2}  \\0.5 = b \\  b = 0.5 \\ a = 5 - b \\  = 5 - 0.5 \\  = 4.5 \\  {a \: }^{2}  -  {b}^{2}  = ( {4.5}^{2})  - (  {0.5}^{2} )  \\  = 20.25 - 0.25 \\  = 20 \\  {a}^{2}  -  {b}^{2}  = 20

Step-by-step explanation:

If tan theta = 12/5 and cos theta < 0, what is sin theta ?
Talja [164]
1 + tan ² Ф=sec²Ф
1+(12/5)²=sec²Ф
169/25=sec² Ф
sec Ф=⁺₋√(169/25)=⁺₋13/5

sec Ф=1/cos Ф ⇒cosФ=1/sec Ф
 cos Ф>0   ⇔  sec Ф>0  ⇔  sec Ф=+ 13/5

cos Ф=1/secФ
cos Ф=1 / 13/5=5/13

we can calculate the sin Ф, with this method.
sin²Ф + cos²Ф=1  ⇒ sin Ф=⁺₋√(1-cos² Ф)
sin Ф=⁺₋√[1-(5/13)²]=⁺₋12/13
like cos Ф>0 and tan Ф>0   ⇒ sin Ф>0 ⇒sin Ф=12/13

answer: d.12/13

other method
tan Ф=sin Ф / cos Ф
12/5=sin Ф / 5/13
sin Ф=(12/5)*(5/13)=12/13

answer: d.12/13
