First, you should find a common denominator:
Turn 2/5 into 4/10 by multiplying by 2.
Then, find the difference in your fractions:
7/10 - 4/10 = 3/10.
Your answer is 3/10.
the shorter sides are 4 inches and the longer sides are 21 inches long
Answer:
t=+4.06
Step-by-step explanation:
when the baseball hits the ground, the height will be 0.
h=0we are given that h=−16t2+64t+4.
this means that the height is 0 when −16t2+64t+4=0.−16t2+64t+4=0divide both sides by 4:−4t2+16t+1=04=0−4t2+16t+1=0 can be solved using the quadratic formula:t=−b±√b2−4ac2a, where at2+bt+c=0.at2+bt+c=−4t2+16t+1a=−4,b=16,c=1t=−b+√b2−4ac2aor−b−√b2−4ac2a−b+√b2−4ac2a=−16+√272−8=−0.06..−b−√b2−4ac2a=−16−√272−8=4.06 (3s.f.)we have 2 values for t:−0.06 and 4.06.
since time cannot be negative, only the positive value can be taken.
this is 4.06, to 3 significant figures.the time taken is 4.06 seconds.
Positive 2 is your slope, (rise over run) if you have to graph it and -1 is your y-intercept
D. 4.81 x 10^13
Move the decimal to the right 13 times, because when you multiply by 10, you make the number bigger, when you divide you move the decimal to the left to make the number smaller.
