Answer:
$6.48
Step-by-step explanation:
$1.50 × 4 = <u>$6.00</u>
for sales tax, $6.00 × 0.08 = <u>$0.48</u>
$6.00 + $0.48 = <u>$</u><u>6</u><u>.</u><u>4</u><u>8</u>

Answer:
a). 59.049°C
b). 2.1179 seconds
Step-by-step explanation:
Expression representing the final temperature after decrease in temperature of the metal from 100°C to T°C is,
T =
where x = duration of cooling
a). Temperature when x = 5 seconds
T = 100(0.9)⁵
= 59.049
≈ 59.049°C
b). If the temperature of the metal decreases from 100°C to 80°C
Which means for T = 80°C we have to calculate the duration of cooling 'x' seconds
80 =
0.8 =
By taking log on both the sides
log(0.8) =log[]
-0.09691 = x[log(0.9)]
-0.09691 = -0.045757x
x =
x = 2.1179
x ≈ 2.1179 seconds
Answer:
A (Only A)
Step-by-step explanation:
the X position can NOT repeat itself at all. In A it does not do that but in the rest it does
in B there is a 2,5 and a 2,2 (Repeating X)
in C there is a -1,4 and a -1, 7 (Repeating X)
in D there is a 3,1 and a 3,2 (Repeating X)
