Marianna [84]3 years ago
4 0

Answer:

  • 5) m/5 = 7/2 ⇒ m = 5*7/2 ⇒ m = 35/2
  • 6) 7/4 = r/5 ⇒ r = 5*7/4 ⇒ r = 35/4
  • 7) 7/6 = 5/x ⇒ x = 5*6/7 ⇒ x = 30/7
  • 8) 6/5 = 2/(5n) ⇒ 5n*6 = 5*2 ⇒ n = 10/30 ⇒ n = 1/3

7. Write a paragraph proof of theorem 3-8: in a plane, if two lines are perpendicular to the same line, then they are parallel t
aliina [53]

Step-by-step explanation:

Assume that two lines x and y are perpendicular to the line z.

+) x intersects z at point A => Angle A1 = 90°

+) y intersects z at point B => Angle B1 = 90°

As it can be seen from the figure that Angle A1 and Angle B1 are corresponding angles and they are congruent.

According to the corresponding angle theorem, when two parallel lines are cut by a transversal, the pair of corresponding angles are congruent and vice versa, when two lines are cut by the same line and the pair of corresponding angles are congruent, they are parallel.

=> x and y are parallel.

The function below describes the number of students who enrolled at a university, where f(t) represents the number of students a
dem82 [27]

Answer:

18,500  , 1 , 1.03

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

f(t) =18,500(1.03)^t  

1st blank:

19,055

1.03

3

18,500

2nd blank:

t years

2 years

3 years

1 year

3rd blank:

19,055

3

18,500

1.03

My answer:

Given that:  f(t) =18,500*1.03^{t}

1st blank:

Initial value when t = 0, so we have:

f(0) =18,500*1.03^{0}

f(0) =18,500(1)\\ f(0) =18,500

So we choose D for 1st blank

2nd and 3rd blank:

Because it's an exponential function f(t) =18,500*1.03^{t}  , with every value of t increment f(t) increase by a factor of 1.03 . So  Every  1 year the number of students who enroll at the university increases by a factor of 1.03

=> 2nd blank: 1

=> 3rd blank: 1.03

Hope it will find you well.

The cost of a customer's smartphone bill can be modeled by
Sergio039 [100]

Answer:

C = (g + 5)

Step-by-step explanation:

Given the cost of a customers smartphone bill,

C=10g+50

We are required to factor the polynomial.

First, determine the G.C.D of both terms

    The GCD of 10g and 50 is 10

Next, we divide each of the term by 10 and balance it by multiplying the expression by 10.

C = 10g + 50

 = 10 (10g / 10 + 50/10)

The cost polynomial factored is C=10(g+5).
