Answer:
x+2 < 11 and -x-2 < 11
Step-by-step explanation:
absolute value function has two solution
|x| = a
Then x=a and - x= a
|x + 2| < 11
Then x + 2 < 11 and -(x + 2) < 11
x + 2 < 11 and -x - 2 < 11
Answer:
Step by step explanation: OK so your question is 26.35×21.5 so that is pretty easy but if you do not know that you are in the right place so what you’re gonna do is if you have a calculator then you need to take that out if you don’t then I’m going to need a piece of paper now for me it’s easy because I have a calculator and you can find a calculator on your iPad your phone etc. but yeah so you’re gonna type in 26.35 Times 21.5 now I want u do that on your own once you type in those numbers you’re going to hit the = and it’s that simple and you’ll then get your answer so I hope that helped you to learn how you multiply those the numbers.
The equation f(t) = -16t² + 176t is a quadratic equation, and so its maximum must be found at its vertex. In order to get this, you can use the formula
t = -b/2a.
Substituting, we have:
t = -176/2(-16) = 5.5 seconds.
But this is just only the time needed for the flare to reach its maximum height. To solve for the time the flare has been in the air, we multiply the maximum height by 2.
2 x 5.5 seconds = 11 seconds.
Answer:
Step-by-step explanation:
100%-17.5%= 82.5%
82.5% (divide) 82.5%= 1%
so (1% of the orginal price)=
£264 (divide) 82.5%= £320= original price
