Answer:

5 units

Step-by-step explanation:

(2,6) and (7,6)

Since the y coordinates are the same, we only need to look at the x coordinates

The distance between 2 and 7 is

7-2 =5

5 units

Answer:

5 units

Step-by-step explanation:

Since the y values are the same, they are already on the same vertical line. This means that we simply need to go horizontally in order to get the distance, which we could do two ways.

We could:

1.) Count the units on a graph

2.) Subtract the points to get our distance

The most simple and practical option would be 2, so when we subtract (7,6) from (2,6) we should get 5 units.

*Note*: you could also do it the other way around, and you would get -5, but of course, distance can't be negative so you would simply take the absolute value and still get 5

Determine the displacement of end A with respect to end D if the diameters of each segment are dAB = 0.85 in ., dBC = 1.1 in .,

ipn [44]

Answer / Step-by-step explanation:

It should be noted that the question is incomplete due to the fact that the diagram has not been provided. However, the diagram has been complementing the question has been provided below.

To solve the question in the narrative, we recall the equation used in solving for displacement:

Thus, δₙₐ = Σ pL/AE

Where:

P is applied axial force.

E is the young's modulus of elasticity.

A is the area of cross-section.

L is length of the bar

Therefore, -8 (80) ÷ π/4 ( 0.85)² (18) (10³) + 2(150) ÷ π/4 (1.1)² (18) (10³) + 6(100) ÷ π/4 (0.45)² (18) (10³)

Solving further,

we have,

-8 (80) ÷ 0.7853( 0.85)² (18) (10³) + 2(150) ÷ 0.7853(1.1)² (18) (10³) + 6(100) ÷ 0.7853 (0.45)² (18) (10³)

= -640÷ 0.7853( 0.85)² (18) (10³) + 300 ÷ 0.7853(1.1)² (18) (10³) + 600 ÷ 0.7853 (0.45)² (18) (10³)

Solving further, we arrive at 0.111 in answer.

The positive sign indicates that end A moves away from end D.

If 12 cars are needed o get 36 students to the end of the road with their packs, how many cars will be able to carry 9 students

Alina [70]

Answer:

3 cars

Step-by-step explanation:

If 12 cars are needed to carry 36 students,

12cars = 36

the number of cars to carry 9 students will be:

xcars = 9

cross the two equations

36x = 12 X 9

36x = 108

x = 108/36

x= 3

Therefore, 3 cars are needed to carry 9 students

12 cars will carry 36 students

so 1 car will carry, (36/12)students

therefore, 1 car will carry 3 students

So, for 9 students,

9students = 9/3 = 3

What is the other square root of 119 + 120i?

MakcuM [25]

Answer:

$\sqrt{119+120 i}=\pm (12.24+i 4.90)$

Step-by-step explanation:

Given

z = 119 + 120 i

Let $\sqrt{119+120 i}=p+iq$

Squaring both sides

$119+120 i=p^2-q^2+2ipq$

Comparing real and imaginary part

Re(LHS)=Re(RHS)

$119=p^2-q^2$ ...........................(1)

comparing Im(LHS)=Im(RHS)

120=2pq

$q=\frac{60}{p}$

Substitute q in 1

$119=p^2-(\frac{60}{p})^2$

$p^4-119p^2-(68)^2=0$

Let $x=p^2$

$x^2-119x-4624=0$

$x=\dfrac{119\pm \sqrt{119^2+4\times 4624}}{2}$

$x=\frac{119\pm 180.71}{2}$

we take only Positive value because $p^2=x$

x=149.85

$p^2=149.85$

thus $p=\pm 12.24$

$q=\pm 4.90$

thus,

$\sqrt{119+120 i}=\pm (12.24+i 4.90)$
