<em>Comment on questions of this type</em>
Perhaps the point of this exercise is to help you understand that the average slope computed by the first expression approaches the instantaneous slope computed by the second expression. This happens when a approaches x and when h approaches zero.
In this problem, where the function is a straight line, the slope is a constant (-3), so the average slope and the instantaneous slope are the same everywhere (for all values of x, a, h).
Answer:
Q1. 20x = 200. The value of x is 10
Q2. 7 - 3x = 1. The value of x is 2.
Step-by-step explanation:
In order to find an equation, you have to let the number be any variable, such as m or n or z. So I will let the number be <em>x variable</em>. Then the question says a number is multiplied by 20 is equals to 200 :
Let number = x,
Same for the next question. Given that a number multiplied by 3 :
Let number = x,
Then subtracted by 7 equals to 1 :
The option that expresses the age of tree in scientific notation with the lowest level of precision would be A. 3 X 10 to the 3rd power. As it contains the fewest number of significant figures.
Answer:
Its C.6
Step-by-step explanation:
Because a^2+8^2=10^2
300/x=100/84
<span>(300/x)*x=(100/84)*x - </span>we multiply both sides of the equation by x
<span>300=1.19047619048*x - </span>we divide both sides of the equation by (1.19047619048) to get x
<span>300/1.19047619048=x </span>
<span>252=x </span>
<span>x=252</span>
