Step-by-step explanation:
Given formula
an = n² + 4
Now the first four terms of the sequence are
a1 = 1² + 4 = 5
a2 = 2² + 4 = 4 + 4 = 8
a3 = 3² + 4 = 9 + 4 = 13
a4 = 4² + 4 = 16 + 4 = 20
The terms are
5 , 8 , 13 and 20.
The answer should be C. 3
Answer:
Should be 10 if there is nothing for th stem value of 3.
Step-by-step explanation:
The stem is the tens place, and the leaf is the ones. You would get 28 40 43 43 45 50 50 for your numbers. If you take Q3-Q1, you get your answer, 10.
Equation of the straight line can be given in more form. The most common forms are implicit (general or standard) form ax+by+c=0 and explicit form y=kx+i, where k is line coefficient and l is cut which line made on the y axis. If k>0 then the angle that takes straight line with the positive direction to the x axis is sharp and if k<0 then the angle that takes straight line with positive direction to the x axis is obtuse. In you case you only need to form one monomial with variable y in the given equation in the following way: 3x-4y+7=3y => add to both side (-3y) and you get 3x-4y-3y+7=3y-3y finally we get implicit or general 3x-7y+7=0. If is it necessary to transform from the implicit into the explicit form we will do this in the following way: 3x-7y+7=0 add to both side expression (-3x-7) => 3x-3x-7y+7-7=-3x-7 => divide both side with (-7) => y= (-3x-7)/ (-7) => finally we get y=3/7 x + 1 ( in our case coefficient of direction k=3/7 and the cut which line is made3 on the y axis l=1). Its display in the decartes coordinate system is given in one of the already given answers.
Answer:
B) 0.99
Step-by-step explanation:
sin(12) = 0.2
pie = 3.14
3.14 x 0.2 =0.6
0.6 / 7 = 0.9
:) hope that's alright aha
