Well, Cutecupcake678 If we do 37°-42° it equals -5° so the temperature change is 42° :)
Answer:
option C
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
And we need to tell which graph best matches the graph we drew. Firstly let's convert it into a quadratic equation by opening and simplifying the brackets.
y = ( x + 2) ( x - 3)
y = x ( x - 3)+2( x - 3)
y = x² - 3x + 2x -6
y = x² - x - 6
Now plot its graph. For that refer to attachment.
<u>Things </u><u>we </u><u>can</u><u> </u><u>interpret</u><u> </u><u>:</u><u>-</u><u> </u>
- The constant in the equation is -6. So the graph will cut y axis 6 units below the X axis . At (-6,0)
- From the given options , option C matches the above point .
<u>Therefore</u><u> the</u><u> </u><u>correct</u><u> </u><u>option</u><u> </u><u>is </u><u>(</u><u>C)</u><u> </u><u>.</u>
Answer:
80
Step-by-step explanation:
64s : Xg
4s.Xg = 5g.64s
X = (5g*64s)/4sg
= 5*64/4
= 5*16
= 80
Step-by-step explanation:
The formula to find the final velocity, v of an object having an initial velocity , u , and acceleration , a , at time t is v=u+at
(a) v=u+at
Subtract u from both sides,
v-u=u+at-u
v-u=at
Dividing both sides by t.
(b) The relationship between the acceleration and time for a given initial and final velocity is given by "
Where
s is the distance covered
t is the time
Hence, this is the required solution.
