Answer:
<h3>9.43</h3>
Step-by-step explanation:
The formula for calculating the distance between two points is expressed as
D =√(x2-x1)²+(y2-y1)²
Given the coordinates (0,0) and (8,5)
D = √(5-0)²+(8-0)²
D = √5²+8²
D = √25 + 64
D = √89
<em>D = 9.43</em>
<em>Hence the distance between the life guard and the swimmer is 9.43</em>
<em></em>
The answer to this will be 3 1/8
3 1/4 – 1 7/8 = 3 1/8
If the probability of the event A is P(A) and the probability of the event B is P(B), then the probability P(A and B) is P(A)*P(B).
Since both P(A) and P(B) are equal to 1/2, then:
Answer:
7)
8)
Step-by-step explanation:
7) The equation of the straight line passing through the ordered pair (-3,5) and (3,-5) is given by
⇒ -3(y - 5) = 5(x + 3)
⇒ -3y + 15 = 5x + 15
⇒ 5x + 3y = 0
⇒ (Answer)
8) The equation of the straight line passing through the ordered pair (5,7) and (11,16) is given by
⇒ 2(y - 7) = 3(x - 5)
⇒ 2y - 14 = 3x - 15
⇒ 3x - 2y - 1 = 0
⇒ (Answer)
Answer:
The answer is below
Step-by-step explanation:
The equation of a linear function is given as:
y = mx + b;
where y, x are variables, m is the rate of change and b is the initial value of variable y.
A) Since there is B bacteria in the Petri dish at 12:00 midnight and the number of bacteria increases after midnight by 25 every hour. Let h represent the time in hours and T represent the total number of bacteria, therefore the equation is:
T = 25h + B
B) Given that B = 5, h = 6, hence:
T = 25(6) + 5 = 150 + 5 = 155 bacteria
C) The equation of the graph is:
T = 25h + 5
The graph was plotted using geogebra online graphing.
