The equation of the new route if it is to be perpendicular to the old route and will go through point (P, Q) is y - Q = -\frac{5}{2}(x - P)

Since the equation of the path of the old route can be described as y = two fifthsx − 4, it is y = \frac{2}{5}(x - 4)

Now the gradient of this old route is m = 2/5.

Since the new route is perpendicular to the old route, if we let its gradient be  m', then mm' = -1 (since the routes are perpendicular).

So, m' = -1/m

m' = -1/2/5

m' = -5/2

So, the gradient of the new route is m' = -5/2.

Since the new route passes through the point (P, Q), the equation of the new route passing through this point is given by

(y - Q)/(x - P) = m'.

\frac{y - Q}{x - P} = m'

This is the equation of the new route given in gradient form where m' is the gradient of the new route.

Since m' = -5/2,

\frac{y - Q}{x - P} = m'

\frac{y - Q}{x - P} = -\frac{5}{2}

y - Q = -\frac{5}{2}(x - P)

So, the equation of the new route if it is to be perpendicular to the old route and will go through point (P, Q) is y - Q = -\frac{5}{2}(x - P)

Given MTS and SQP, find sq
STALIN [3.7K]

The measure of the side SQ from the given diagram is 19/6

<h3>Similar shapes</h3>

Similar shapes are shapes that has equal length and equal side measures and angles.

From the given diagram, the measure of the sides TSis congruent to SP and the measure of MS is congruent to SQ.

Using the expression below to determine the value of x

MS/ST = SQ/SP

Given the following parameters

MS =30

ST = 10

SQ = 6x-1

SP =  3 - 2x

Substitute the given parameters into the formula to have:

30/10 = 6x-1/3-2x

Cross multiply

10(6x-1) = 30(3-2x)

Expand

60x - 10 = 90 - 60x

60x + 60x = 90 + 10

120x = 100

x = 10/12

x = 5/6

Determine the measure of SQ

SQ = 6x - 1

SQ = 5(5/6) - 1

SQ = 25/6  - 1

SQ = 19/6

Hence the measure of the side SQ from the given diagram is 19/6

Sveta_85 [38]

Answer:

1.2 liters

Step-by-step explanation:

7/7 of a liter is one liter. and you still are only at 7. you need to get to 9 you and 2 1/7 liters and that becomes 9/7 liters which = 1.2

Suppose that P(n) is a propositional function. Determine for which improper subset of the domain of n the statement P(n) must be
Alinara [238K]

Answer:

a) P(n) is true for all 'n' in the set ; { 0,2,4,6,8 ….. }

b) P(n) is true for all 'n' in the set ; { 0,1,2,3,4,5 ............ }

Step-by-step explanation:

a) As P(0) is true

we will assume that

  • P(2) is true
  • P(4) is true
  • P(6) is true

this simply means  that ;  P(n) is true for all 'n' in the set

{ 0,2,4,6,8 ….. }

b) since P(0) and P(1) are true

we will assume that

  • P( 0+2 ) = P(2)  is true

also P(1) and P(2) are true

we will assume that

  • P(1+2) = P(3)  is true

Also from the previous answers it can be seen that P(2) + P(3) is true

we will assume

  • P(2+2) = P(4)  is true

This simply means that P(n) is true for all 'n' in the set

{ 0,1,2,3,4,5 ............ }
