Answer:
The 4th term in the sequence is -18.
Step-by-step explanation:
The <em>n</em>th term of a sequence is given by the relation:
Compute the 4th term in the sequence as follows:
Thus, the 4th term in the sequence is -18.
Answer:
it's basically just saying find the X that if it's mapped to Z would still have the same X value

Answer: 6 gallons </h2>
First we are told that we initially had 1/3 of the tank and when 10 gallons were added we had 3/4 of the tank:
(1)
(2)
(3)
This means 1 gallon is equivalent to 1/24 tank.
On the other hand if we have 3/4 of a tank and need to reach 1 tank we have to add another fraction of the tank:
(4)
(5)>>>>This is the fraction needed to complete 1 tank
Now we need to know <u>how much that 1/4 tank is equivalent in gallons</u>.
From (3) we know . So, we can write the following relation to transform from fractions of a tank to gallons:
Therefore:
<h2>
6 more gallons are needed to fill the tank</h2>
Answer:
a
Step-by-step explanation:
Given
u = (x₁, y₁, z₁ ) and v = (x₂, y₂, z₂ ) then the dot product is
u • v = (x₁ x₂ ) + (y₁ y₂ ) + (z₁ z₂ )
Then
v • w
= (5 × 9) + (- 4 × - 2) + (4 × 7)
= 45 + 8 + 28
= 81 → a
Answer:
116°F = 46.67 °C and 6 Pounds = 2721.55 grams
Step-by-step explanation:
The information given in the question is 1°F = -17.22°C
1 Kilogram = 1000 grams = 2.2 pounds
And we have to convert 116° F to degrees Celsius and Six pounds to grams.
1) We know (°F-32)×5/9 =°C
So by putting the value of °F as 116 ⇒ (116-32)×5÷9 = °C
⇒ °C =
⇒ °C = 46.67
2). ∵ 2.2 Pounds = 1000 grams
∴1 Pound = 1000/2.2 = 454.54 grams
∴ 6 pounds = 6× 454.54 grams
= 2721.55 grams
