Mathematics
1 answer:
daser333 [38]3 years ago
7 0

Answer:

A) 78

Step-by-step explanation:

The given sequence is an arithmetic sequence.

Here A1 = -6, common difference = (3/2)

nth term An = a1 + (n -1)d

A57 = -6 + (57 -1)3/2

= -6 + (56)*3/2

= -6 + 28*3

= -6 + 84

A57 = 78

Thank you.

Help please I don’t understand it
Jlenok [28]

Answer:

15) 30

16) 2

for 15 you plug the -4 into the variable (x)

so...

-4(-4)-4-2-5(-4)

you do multiplication first because of PEMDAS

so -4×-4=16 it is not negative because there 2 negatives so they cancel out

then -5×-4=20

then you get this:

16-4-2+20 which equals 30

then with 16 you do the same. you just put the number for y in the variable y and same with x

xeze [42]

Answer:

66.75 is the answer

Step-by-step explanation:

Just plug in the x and solve

4(2 , 5/8) + 9[2(2 , 5/8) + 1]

solve

4 × 2 , 5/8 + 9[2×2 , 5/8 + 1]

10.5 +9[2×2 , 5/8 + 1]

10.5 +9[5.25 + 1]

10.5 +9[6.25]

10.5 + 56.25

66.75

Write down the coordinates of the letters A, B, C, D, E, F, G, H from the below graph..
miskamm [114]

Answer:

A = (2,1)

B = (4,2)

C = (5,3)

D = (6,6)

E = (4,6)

F = (3,4)

G = (1,6)

H = (6,0)

I = ( 0, 4)

Step-by-step explanation:

tips:

the format for coordinates is (x,y)

the horizontal line is the x axis, so you plot which number of x it lands on, like how A is on the second mark on the x axis.

The vertical line is the y axis, so you plot which number of y it lands onn like how A is on the first mark
