Step-by-step explanation:
12 times 4 + 12 + 48
A.
n=1 is -4*1=-4
1st term is -4
2nd is -4/3
3rd is -4/9
4th is -4/27
b. converge because -1<r<1
c. as long as -1<r<1, then
the sum of the infnite series is
a1=-4
r=1/3
=
=-12/2=-6
it has a sum of -6
sum of gemoetric sequence is
a1=6
r=2
n=10
6138
2nd answer
3*5+4*5+5*5+6*5+7*5+8*5=
5*(3+4+5+6+7+8)=
165
answer is 4th one
Step-by-step explanation:
the inverse function simply calculate the original x it of a given y. so, we need to transform the original function to calculate x instead of y.
and then, at the end to make it a formally correct function definition, we rename x to y and y to x.
y = x + 3
x = y - 3
=> to make it a formally correct function definition
y = x - 3 = h(x)
Answer:
Use pythagoreum theorem to determine whether it is or isn't since I'm not really sure myself but here's my calculations.
Step-by-step explanation:
We need to find AC.
Picture a triangle called ABC. AB is one side and BC the other while AC is the hypotenuse.
AC=
Round up the 7.6 to a whole number and you get AC=8. To get perimeter of a triangle simply add the sides together to get 18.
Not really sure about my answer but hope this helped.
1 would be 4 with an open circle that points to the right
2 would be 6 with a closed circle that points to the left
