Answer:
c
Step-by-step explanation:
When approaching 2 from the left, there is an open circle.
Also, the left part of the graph has a y-intercept of 2.
<u><em>(The Explanation):</em></u> What we are given is that the car drives 45 miles each hour. Furthermore, you need to multiply the amount of hours desired to the miles to get a total mile.
<u><em>(Step-By-Step Instructions):</em></u>
<em>45(4) and 45(20) </em> Multiply
<u><em>The Answers:</em></u> 4 hours = 180 miles / 20 hours = 900 miles
Answer:
1) gradient (00) (-2 4) = y2-y1 / 2-1 = 4/-2 = -2 m = -2/1 means = m = -2 (negative slope) 2) gradient y2-y1 / x2-x1 = 3-0 / 2-0 = 3/2 = (1 1/2)/1 m = 1 1/2 (positive slope) we use the formula y-values divided by the change in the x-values. The equation of the gradient each goes like this 1) y = -2x as y is at origin nothing else to add The equation of the gradient each goes like this 2) y = 1 1/2x The equation of the point formula 1) we take the y -y1 = m (x +x 1) = y-0 = -2x (x +0) (as m = -2) y = -2(x +0) and The equation of the point formula 2) y - 0 = m ( x +x1) y - 0 = 1 1/2( x +0) = y = 1 1/2( x +0)
To reflect it over the x axis, all y units get multiplied by -1, so we multiply the equation by -1. After that, to stretch it vertically, we multiply it by that factor, which is 2. Right now , we have -2log(5x). Lastly, we shift it down 3 units by subtracting 3 from the overall equation, resulting in -2log(5x)-3
Answer:
70/100
Step-by-step explanation:
Surface of the earth covered with water = 7/10
Equivalent fraction of 7/10 with 100 as the denominator = 70/100
This means 70% of the earth surface is covered with water
Percentage covered with land = Total percentage - percentage covered with water
= 100/100 - 70/100
= 100-70/100
= 30/100
Percentage covered with land = 30%
