Answer:
1.) The 1ˢᵗ three term is (-32), (-7) and 18
2.) The 1ˢᵗ three term is 127, 106 and 85
Step-by-step explanation:
<h2>1.)</h2>
Here,
First Term = a₁ = - 32
Common Difference = (d) = 25
Now, For 1ˢᵗ three term,
<u>n = 1</u>
a₁ = - 32
<u>n = 2</u>
aₙ = a + (n - 1)d
a₂ = (-32) + (2 - 1) × 25
a₂ = (-32) + 1 × 25
a₂ = (-32) + 25
a₂ = -7
<u>n = 3</u>
<em>aₙ = a + (n - 1)d</em>
a₃ = (-32) + (3 - 1) × 25
a₃ = (-32) + 2 × 25
a₃ = (-32) + 50
a₃ = 18
Thus, The 1ˢᵗ three term is (-32), (-7) and 18
<h2>2.)</h2>
Here,
First Term = a₁ = 127
Common Difference = (d) = -21
Now, For 1ˢᵗ three term,
<u>n = 1</u>
a₁ = 127
<u>n = 2</u>
aₙ = a + (n - 1)d
a₂ = 127 + (2 - 1) × (-21)
a₂ = 127 + 1 × (-21)
a₂ = 127 - 21
a₂ = 106
<u>n = 3</u>
<em>aₙ = a + (n - 1)d</em>
a₃ = 127 + (3 - 1) × (-21)
a₃ = 127 + 2 × (-21)
a₃ = 127 - 42
a₃ = 85
Thus, The 1ˢᵗ three term is 127, 106 and 85

Answer:
The volume of the pyramid is 9 in3.
The volume of the prism is 85.5 in3.
The volume of the monument replica is
94.5 cubic inches.
Step-by-step explanation:
It's the answer on edge, and I got it right
Yes, J can be determined if H=54. The interior angles of a triangle always add up to 180. Since we know H=54 and J and I are equal.
J+I+H=180
J+I+54=180
J+I= 126
Because J&I are equal you can just divide 126 by 2
J=126/2
J= 63
93 - 30 = 63
I hope I helped! Let me know if you need more help!
Oh well, she babysitted for $63/$9 = $7
