Answer:
Step-by-step explanation:
<u>Given the sequence</u>
<u>To find </u>
- Sum of terms from i=5 to i=15
<h3>Solution</h3>
We see the sequence is AP
<u>The required sum is</u>
<u>Using sum of AP formula</u>
<u>Finding the required terms</u>
- i₁ = - 4- 6 = -10
- i₄ = -4 -6*4 = - 28
- i₁₅ = -4 -6*15 = -94
<u>Getting the sum</u>
- S₄ = 1/2*4*(-10 - 28) = -76
- S₁₅ = 1/2*15*(-10 - 94) = -780
- S₅₋₁₅ = S₁₅ - S₄ = -780 - (-76) = - 704
Answer:
CD=28
FD=16

have a great day!!
22 dollars, because if we add 10 onto that grand total then divide we get what it would cost one 1 day which seems to be 22 dollars
Answer:
.797
Step-by-step explanation:
If your talking about a decimal number, you would say the <u>thousandth</u>. I know, weird, but don't blame me.
To round up, any number above 5 rounds up to the next value place, and any number below 5 rounds down to the last value place.
Ex: 1.3483838383
Since 8 is greater than 5, we could get rid of all the 83s and just round up to 1.35.
So the thousandths place in a decimal would be 0.79<u>6</u>66357977, so we just ask if the next number after the thousandths place is greater than 5. The place number after .796 is 6, so since it is greater than 5, we would round up to .797.
Our answer is .797.
