Henry counted units to find the distance between two points. For which pair of points could he have done this ? Select all that
Flura [38]

Options:

(–3, 5) and (–2, 5)         (–3, 5) and (–9, 3)

(5, 3) and (9, 3)             (5, –9) and (3, –5)

(2, 3) and (7, 3)

Answer:

(–3, 5) and (–2, 5)

(5, 3) and (9, 3)

(2, 3) and (7, 3)

Step-by-step explanation:

To do this, have to compare the both x and both y coordinates of the points.

If the x coordinates are equal or the y coordinates are equal, then that option is true

For (a): (-3,5) and (-2,5)

The y coordinates are the same:

i.e.

y_1 = y_2 = 5

<em>This option is true</em>

For (b): (-3, 5) and (-9, 3)

None of the coordinates are the same;

i.e.

x_1 \ne x_2

y_1 \ne y_2

<em>Hence, this option is false.</em>

For (c): (5, 3) and (9, 3)

The y coordinates are the same:

i.e.

y_1 = y_2 = 3

<em>This option is true</em>

For (d): (5, -9) and (3, -5)

None of the coordinates are the same;

i.e.

x_1 \ne x_2

y_1 \ne y_2

<em>Hence, this option is false.</em>

(2, 3) and (7, 3)

The y coordinates are the same:

i.e.

y_1 = y_2 = 3

<em>This option is true</em>

If (a²-1/a²)=23 find the value of i) (a+1/a), ii) (a³+1/a³)​<br><br>pls help me
vesna_86 [32]

Answer:

5

Step-by-step explanation:

(a + (1/a)2 =  a2 + (1/a2) + 2

⇒ (a + (1/a))2 = 23 + 2

⇒ (a + (1/a))2 = 25

⇒ a + (1/a) =

⇒ a + (1/a) = 5

a3+b3=

(a+b)

(a2−ab+b2)

where  a=a

and b=1/a.

so sum it up u get -1

The next model sports car will cost 5.2% more than the current model. The current model costs $55,000. How much will the price i
Lady_Fox [76]

Answer: The price increase = $2,860.

The price of the next model will be $57,860.

Step-by-step explanation:

Given: The next model sports car will cost 5.2% more than the current model.

Current model costs $55,000.

Price increase = 5.2%  of (Cost of current model)

= (0.052) x ($55000)

= $ 2860

So, the price increase = $2860.

Price of the next model = Cost of current model +  price increase

= $(55000+2860)

= $ 57,860

Hence, the price of the next model will be $57,860.
