Answer:

Distance between (-7, 8) and (6, 4)

= √ [ (4-8)^2 + (6-(-7))^2 ]

= √ [ (-4)^2 + (13)^2 ]

= √ [ 16 + 169 ]

= √ [ 185 ]

= 13.60

which is 14 units

Jamal has $15.00 to spend at the concession stand. He buys nachos for $7.50, and he wants to purchase some sour straws for $1.50
GalinKa [24]

Answer:

x = 5

$15.00 is the total amount of money Jamal has right? To find the remaining amount of money Jamal has subtract 15 - 7.5 (price of nachos) = 7.5 (remaining amount of money Jamal has.) Now for part 2, since the sour straws are $1.50 each you just have to multiply X to get close as close to the remaining amount of money as possible.

1.50× 5 (amount of sour straws) is equal to 7.50 (price of 5 sour straws).

To check your answer let's add the price of nachos (7.50) and 5 sour straws (7.50) which is 15.00 the total amount Jamal brought with him.

Let me know if you have any other questions :)

(4x + 3)(4x - 3)<br> Help pls
tekilochka [14]

Answer:

16x^2-9

Step-by-step explanation:

\left(4x+3\right)\left(4x-3\right)

We´ll <u>Apply Difference Two Squares Formula:</u>

  • \left(a+b\right)\left(a-b\right)=a^2-b^2

\longmapsto \left(4x+3\right)\left(4x-3\right)

\longmapsto \left(4x\right)^2-3^2

<u>Apply exponent rule</u>:

  • \left(a\times \:b\right)^n=a^nb^n

\longmapsto 4^2x^2-3^2

\longmapsto 16x^2-9

A bug splatters on the windshield of a moving car. Describe the 1. Forces 2. Impulses 3. Momentum changes 4. And accelerations o
uranmaximum [27]

Answer:

acceleration=force/mass

Due to variation in the mass[ as same force as per magnitude acts on both of them] the acceleration developed in the bug will be more and the acceleration developed in the car is negligible.

impulse=change in momentum

The impulse of bug is more and that of car is small.

momentum changes=change in momentum

force=change in momentum/time of contact

the force exerted by car on the bug will be more than the converse

Total. momentum is conserved , so magnitude of change in momemtum or impulse is same. By Newtons third law, since the bug have smaller mass, its change in magnitude of velocity is larger.
