Answer:

13.6 KM/H

Step-by-step explanation:

So we know the formula for speed is:

S = $\frac{D}{T}$

The s is for speed, d for distance and t for time

S= $\frac{98KM}{7.2 HRS}$

S= 13.6111111

S= 13.6

Because 13.6111111 is too long we can round it off so the answer becomes 13.6km/h

30. Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

tamaranim1 [39]

Equation in point-slope form is $y-9=4/5(x+7)$

Option C is correct.

Step-by-step explanation:

We need to Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

The formula used for point-slope form is:

$y-y_1=m(x-x_1)$

We are given slope m = 4/5

Point (-7,9) where x₁ = -7 and y₁ = 9

Putting values in the formula:

$y-y_1=m(x-x_1)\\y-9=4/5(x-(-7))\\y-9=4/5(x+7)$

So, equation in point-slope form is $y-9=4/5(x+7)$

Option C is correct.

The reason why the deaths and recoveries occurs so rapidly in the pandemic

As time goes by the virus expands, and evolves causing more people to get infected. Although people who have made it before when the virus had affected them do not get affected by the evolved virus. People who have weak immune systems when infected die. Therefore, the reason thatthe deaths and recoveries happen to rappidly is because of the virus evolving, when some people are able to withstand it whilst others die.
