Answer:d
Step-by-step explanation:
A power is also an exponent which is how many times you multiply a number by itself to get a product
To get 100 as a product of 10 times itself you would multiply 10x10 which is the same as 10^2
Answer:
x = -1/3
Step-by-step explanation:
We have,
sin(x + 7) = cos(4x + 8)
We need to find the value of x.
We know that,
sin(90-x) = cosx
So,
sin(90-(x + 7)) = cos(4x + 8)
cos(x+7) = cos(4x + 8)
i.e.
(X+7) = (4x+8)
7-8 = 4x-x
-1 = 3x
x = -1/3
<span>The temperature of water in a glass if room temperature is 21 degrees Celsius if a glass is standing one in that room, because room temperature is commonly given as 20 to 22 degrees Celsius, however, if the air in the room goes through temperature variations,then a body of water will heat up or cool down,then the temperature of the water in the glass tends to average out those temperature variations.</span>
Notice, the third decimal place is 9 in 3.469644...
and after the 469 there's a 6, that means we can round that 469 to a 470
3.470.
