Answer:
4.2%
Step-by-step explanation:
percent error = (estimated value - actual value)/(actual value) × 100%
Here, the estimated value is 250 g, and the actual value is 250 g.
percent error = (estimated value - actual value)/(actual value) × 100%
percent error = (250 g - 240 g)/(240 g) × 100%
percent error = 10/240 × 100%
percent error = 0.041666... × 100%
percent error = 4.2%
We are given: Function y=f(x).
First x-intercept of the y=f(x) is 2.
x-intercept is a point on x-axis, where y=0.
Replacing y by 0 and x by 2 in above function, we get
0=f(2)
Second x-intercept of the y=f(x) is 3.
Replacing y by 0 and x by 2 in above function, we get
0=f(3)
We are given another function y=8f(x).
Here only function f(x) is being multiplied with 8.
That is y values of function should be multiply by 8.
Because we have y value equals 0. On multiplying 8 by 0 gives 0 again and it would not effect the values of x's.
Therefore,
x-intercepts of y=8f(x) would remain same, that is 2 and 3.
Multiply the weight in tonnes by the conversion factor ( 1 tonne = 1000 kg) to get the weight in kg's:
170 tonnes x 1000 = 170,000
Now convert to scientific notation, by moving the decimal point to have only 1 digit to the left of the decimal.
To do this, you would need to move the decimal 5 places to the left to get 1.70000
Now remove the 0's and multiply the number by 10 raised to the number of paces the decimal was moved to get:
1.7 x 10^5 kg's.
200=35.27t
Divide 35.72 on both sides

Answer:
a. 40
b. 0
c. 50
Step-by-step explanation:
a) 46 + (-2k) for k = 3 is ...
46 + (-2(3)) = 46 -6 = 40
__
b) 46 + (-2k) for k = 23 is ...
46 + (-2(23)) = 46 -46 = 0
__
c) 46 + (-2k) for k = -2 is ...
46 + (-2(-2)) = 46 +4 = 50
