<h3>
Answer: Sometimes true</h3>
========================================================
Explanation:
-8+d is positive only when d > 8
Here's why
-8+d > 0
-8+d+8 > 0+8 .... add 8 to both sides
d > 8
So if Jessica said "d is greater than 8", then her claim would always be correct.
However, her claim is sometimes true.
Two counter examples could be when d = 1 and d = 2.
If d = 1, then -8+d = -8+1 = -7 which isn't positive.
If d = 2, then -8+d = -8+2 = -6 which also isn't positive.
Basically if d is anything smaller than 8, then you'll have -8+d be negative.
If d is something larger than 8, say d = 9, then -8+d = -8+9 = 1 which is finally positive.
Answer:
79 °F
Step-by-step explanation:
Newton’s Law of Cooling:
Data
- The initial temperature of a liquid is 160 °F
- The temperature in the room (c) is 76 °F
- Then a = 160 - 76 = 84 °F
Replacing into the equation:
y = 79 °F
The area of the sector, when the measure of the central angle is in radians, can be solved using this equation:
A = (n/2) r²
From the given values,
A = (π/6/2) (10²)
A = 25π/6 = 26.18 in²
Therefore, the area of the sector with the central angle measuring π/6 with the radius of the circle 10 inches is 26.18 in²
Answer:
excluded value is 1/2
Step-by-step explanation:
The excluded value is the value when the denominator is equal to zero
1 -2x =0
Subtract 1 from each side
-2x = -1
Divide by -2
-2x/-2 = -1/-2
x = 1/2
The excluded value is 1/2
2 centimeters
When you are measuring and object you use centimeters when you measure distance is kilometers or meter and when you are measuring liquid used millimeters
And if you are measuring a person or something big used meter
I hope It help
