The most simple way is to get 8 questions right on a ten question test. 8q/10q = 80%.
Answer:
a) 8 x 10^3 or 8000
b) 8 x 10^-2 or .08
Explanation: Refer to a guide on rounding sig figs
Answer:
$5.85
Step-by-step explanation:
Divide 29.45 by 5 and the answer equal one pair
Answer:
29,750
Step-by-step explanation:
Each year the population is multiplied by 100% + 4% = 1.04. We want to repeat that multiplication 15 times, once for each of the 15 years. An exponent is what we use to signify (and compute) repeated multiplication. The population will be ...
16,519 × 1.04^15 ≈ 29749.8 ≈ 29,750
Answer:
A. y + 1 = -2(x-2)
Step-by-step explanation:
point-slope equation is : y - y1 = m (x -x1)
remember m= slope value
the given point is (2, -1) therefore we can substitute the values in:
y + 1 = m(x -2)
now to make sure our answer is complete we will solve for the slope:
looking back at the graph, the y-intercept value is 3, therefore we have a point of (0,3) and (2, -1)
with any two points you can determine a slope.
y2 - y1 / x2 - x1
therefore :
-1 -3 / 2 - 0
-4 / 2 = -2
therefore our m value is -2
this makes the completed point-slope equation:
y + 1 = -2 (x - 2) or A
