<u>Solution </u><u>:</u><u>-</u></h3>
Firstly finding common difference of the series
As we know that
• Common difference ( d ) = t₂ - t₁
→ Common difference = 37 - 40
→ Common difference = - 3
Now, as we know that
• Sn ( Sum of n terms ) = n/2 [ 2a + ( n - 1 ) d ]
Substituting n = 1. Since the sum of no. of terms is 10 . And substituting a = 40 ,since first term is 40
=> S₁₀ = 10/2 [ 2(40) + ( 10 - 1 ) -3 ]
=> S₁₀ = 5 [ 80 - 27 ]
=> S₁₀ = 5 × 53
=> S₁₀ = 265
Hence , sum of first 10 terms ( S₁₀ ) = 265
Answer:
the price of a medium pizza without a coupon is 14.73
Step-by-step explanation:
The computation of the price of a medium pizza without a coupon is given below:
Given that
The Price of medium pizza be 10.31 after considering the 30% off coupon
That means it is 70% value
So the 100% value would be
= 10.31 × 1 ÷ 0.70
= 14.73
hence, the price of a medium pizza without a coupon is 14.73
Answer: t(a)= -4a - 48
Step-by-step explanation:
Just plug a into x so you'll get: t(a)= -4(a + 12)
Then simplify it: t(a)= -4a - 48
If it says let t(2) then you will plug 2 into x=> t(2)= -4(2 +12)
which equals to t(2)= -8 -48
t(2)= -56
Hope this help
Answer:
x=15
Step-by-step explanation:
since 6 is 3/4 of 8 and the figures are similar x must be 3/4 of 20
3/4 of 20 is 15
good day to you
Answer:
The inverse is 1/2x +3
Step-by-step explanation:
f(x) = 2x-6
y = 2x-6
Exchange x and y
x =2y-6
Solve for y
x+6 =2y
Divide by 2
1/2x +3 = y
The inverse is 1/2x +3
