Can someone help me with this please
jenyasd209 [6]

To solve the first question, the angles J and K are perpendicular to each other, that means also that the angles are 90 degrees.

Apart from each other.

This is the total angle measure, that means the sum of the smaller angles must equal 90 degrees.

So the expression would be

2x - 9 + 27 = 90

2x + 18 = 90

2x = 90 - 18

2x = 72

X = 72/2 = 36 degrees.

For the second question since w and v are parallel that means the angles are equal to each other


Thus make the expressions and value equal to each other and solve for x

3x + 60 = 120

3x = 60

X = 20 degrees.

The reaction of the body to a dose of medicine can sometimes be represented by an equation of the formR = M^2 (C/2- M/3),where C
mr Goodwill [35]

Answer:

The derivative is \frac{dR}{dM}  =  CM - M^2

Step-by-step explanation:

From the question we are told that

The equation representing the reaction is R = M^2 (\frac{C}{2} - \frac{M}{3}  )

Generally this equation can be represented as

R  =  \frac{C M^2}{2}  - \frac{M^3}{3}

Generally \frac{dR}{dM} as a function of M is mathematically represented as

\frac{dR}{dM}  =  2 * \frac{C M^{2 - 1 }}{2}  +  3 * \frac{M^{3-1}}{3}

=> \frac{dR}{dM}  =  CM - M^2

Determine the relationship described in each table.
densk [106]
For the first table, the y-values are not equally spaced and the ratios of y are not the same, but by plotting them and observing the graph that results, it looks like the points lie on an exponential curve. The second table is linear because when x changes by 1, y changes by 4. The third table is a quadratic model because even if the first differences of y are not the same, the second differences of y have the same value of 8. The fourth table is exponential because the ratio of y-values is 2, which is the same between each set of numbers.
