Answer:

-9 + 21 = t t = 12°C.

Step-by-step explanation:

For this problem lets have t be equal to the original temperature in the beginning of the day. The equation -9 + 21 = t represents this situation because it states that if we add the degrees that dropped to the current degrees  it will give us our original degrees. Solve. -9 + 21 = t (Simply add -9 + 21) -9 + 21 = (+12) 12 = t So, the original degrees in the beginning of the day was 12°C.

The midpoint of (3,4) and (5.5,0)​
meriva

Answer:

(4.25,2)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates and divide by 2

x = (3+5.5) /2 = 8.5/2 =4.25

To find the y coordinate of the midpoint, add the y coordinates and divide by 2

y = ( 4+0)/2 = 4/2 =2

2. Provide the next three terms in the sequence and
vivado [14]

The next three terms of -243, 81, -27, 9 is -3,1, \frac{-1}{3} The given series is geometric series

<u>Solution:</u>

Given, series is -243, 81, -27, 9, …

We have to find the next three terms of the above given series.

Now, the given series can also be written as

-243,-243 \times\left(\frac{-1}{3}\right)^{1},-243 \times\left(\frac{-1}{3}\right)^{2},-243 \times\left(\frac{-1}{3}\right)^{3}

We can say that, above series is in Geometric Progression with first term = -243 and common ratio = \frac{-1}{3}

Then, next three term would be,

-243 \times\left(\frac{-1}{3}\right)^{4},-243 \times\left(\frac{-1}{3}\right)^{5},-243 \times\left(\frac{-1}{3}\right)^{6} \rightarrow-3,1, \frac{-1}{3}

Hence, the next three terms of given G.P series are -3,1, \frac{-1}{3}
