The number of measles cases increased 13.6 % to 57 cases this year, what was the number of cases prior to the increase? (Express

ELEN [110]

Answer:

The number of cases prior to the increase is 50.

Step-by-step explanation:

It is given that the number of measles cases increased by 13.6% and the number of cases after increase is 57.

We need to find the number of cases prior to the increase.

Let x be the number of cases prior to the increase.

x + 13.6% of x = 57

$x+x\times \frac{13.6}{100}=57$

$x+0.136x=57$

$1.136x=57$

Divide both the sides by 1.136.

$\frac{1.136x}{1.136}=\frac{57}{1.136}$

$x=50.176$

$x\approx 50$

Therefore the number of cases prior to the increase is 50.

g Let P be the plane that goes through the points A(1, 3, 2), B(2, 3, 0), and C(0, 5, 3). Let ` be the line through the point Q(

Sedbober [7]

Answer:

(x, y, z) = (1, 1/3, 3 1/3)

Step-by-step explanation:

The normal to plane ABC can be found as the cross product ...

AB×BC = (1, 0, 2)×(2, -2, -3) = (4, 1, 2)

Then the equation of the plane is ...

4x +y +2z = 4·0 +5 +2·3 . . . . using point C to find the constant

4x +y +2z = 11

The direction vector of the reference line is the vector of coefficients of t: (0, -1, 2). Then the line through point Q is ...

(x, y, z) = (1, 2, 0) +t(0, -1, 2) = (1, 2-t, 2t)

The value of t that puts a point on this line in plane ABC can be found by substituting these values for x, y, and z in the plane's equation.

4(1) +(2 -t) +2(2t) = 11

Solving for t gives ...

t = 5/3

so the point of intersection of the plane and the line is

(x, y, z) = (1, 2-t, 2t) = (1, 2-5/3, 2·5/3) = (1, 1/3, 3 1/3)
