You need to be more specific
The net for the prism will consist of all rectangles whereas the net for the pyramid will contain a number of triangles
Answer:
Option: a is correct
a) y= -cos x
Step-by-step explanation:
We could clearly see that the graph of the function passes through a point on the y-axis which is :
(0,-1)
i.e. when x=0 the value of the function y= -1
So we will check in each of the following options by putting x=0 and check whether y= -1 or not.
b)
y=sin x
on putting x=0 we get:
y=sin 0=0≠ -1.
Hence, option b is incorrect.
c)
y= cos x.
we put x=0
y= cos 0=1≠ -1.
Hence, option c) is incorrect.
d)
y= -sin x
we put x=0 to obtain:
y= -sin 0=0≠ -1.
Hence, option d is incorrect.
Hence we are left with option a i.e.
The graph represents the function:
y= -cos x. (Hence, option a is correct)
( Also it satisfies at x=0
since, y= -cos 0= -1 )
Answer:
The formula for the sequence is a(n)=(n-1)+d, where n=any nth ordinal term in the sequence, n-1=the previous term, and where d=a consecutive natural number N beginning with a(n1)=1, a(n2)=2,…
PREMISES
S=1, 3, 6, 10, 15, 21,…
The partial sequence suggests a pattern from left to right where the numbers increase by increasing amounts
ALGORITHM
a(n)=(n-1)+d, where n=any nth ordinal term in the sequence, n-1=the previous term, and where d=a consecutive natural number N beginning with a(n1)=1, a(n2)=2, a(n3)=3, and so forth over the range of the sequence.
PATTERN
(1) 0+1=1
(2) 1+2=3
(3) 3+3=6
(4) 6+4=10
(5) 10+5=15
(6) 15+6=21
(7) 21+7=28
(8) 28+8=36
(9) 36+9=45
(10) 45+10=55
and so forth
