is my question right​

Answer:

d=√((x2-x1)²+(y2-y1)²)

d=√(-4+2)^2 + (2+5)^2

d=√(4+49)

d=√53

Let me know if this helps!

Answer:

Step-by-step explanation:

If you complete the square and double the time to get back to the surface you will have your answer.

d = 2(t^2 - 4t) - 10; Take 1/2 of - 4 and square it. Add the result inside the brackets.

d = 2(t^2 - 4t + (4/2)^2 ) - 10  

d = 2*(t^2 - 4t + 4) - 10 - 2*4  

Did you notice I put the 2*4 outside the brackets and turned it into a minus. The reason that happened is to offset what is inside the brackets that was added here.

d = 2(x - 2)^2 - 18; t^2 - 4t + 4 is a perfect square. that 2 inside the brackets is critically important.  

The 18 is the maximum depth below the surface of the water. (Poor choice of words. Technically - 18 is a minimum). But you want to use t - 2 to make it into 0.     t - 2 = 0 ; t =2  

What that means is that it took 2 minutes to get 18 meters below the surface of the water. He will break the surface of the water 2 minutes later. I don't exactly know how to answer the question. It is 2 minutes to get from the minimum depth to the surface. It is 4 minutes to get to the surface when he begins his dive.

Come back to the surface means d=0

Take positive

t=5s

Answer:

The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches

Answer:

Step-by-step explanation:

oh nice,  SOH CAH TOA   :P

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

SOH CAH TOA is really helpful,  it also reminds me of south pacific for some reason  :D  

Anyway back to math

we want to find an angle and we have the Hyp and the adj sides

to that angle soooo

let's pick CAH since it's got   Adj / Hyp , which we know and will find that unknown angle for us..  :)

Cos(Ф) = Adj / Hyp

Ф = arcCos( adj / Hyp)

Ф = arcCos( 14 /28 )

Ф = arcCos(.5)    ( if you happen to be good with trig functions you can already tell what it's going to be :P  w/o using the calculator)

Ф = 60 °

1a = 60 °

for 1b we know the opp and they hyp and want to find the angle. So let's use SOH  

sin = Opp / Hyp

sin(Ф) = 5/20

Ф = arcSin(5 /20)

Ф = arcSin ( 1/4)

Ф = 14.4775 °

1b = 14 °  ( rounded to nearest degree )

Step-by-step explanation:

Answer:

48

Step-by-step explanation:

Using Uclid's division algorithm, the HCF of 960 and 432 can be obtained as follows:

Here, 960 is greater and 432 is smaller. We divide 960 by 432.

STEP 1:

960 = 432*2 + 96

STEP 2:

Divide divisor (432) by remainder (96)

432 = 96 * 4 + 48

STEP 3:

Divide divisor (96) by remainder (48)

96 = 48 * 2 + 0

Since, remainder at this step is zero (0), so the HCF would be the divisor of this step which is 48.

Thus, HCF of 960 and 432 is 48

Answer:

S = 21.6/G

S = 3.6

Step-by-step explanation:

Inverse variation:

y = k/x

For this problem:

S = k/G

We use the given values of S and G to find k.

9 = k/2.4

k = 9 * 2.4

k = 21.6

The equation is

S = 21.6/G

For G = 6,

S = 21.6/6

S = 3.6

[tex]\huge\boxed{960}[/tex]

Step-by-step explanation:

To find the volume of a rectangular prism we use the formula

Volume = length x height x width

the following dimensions are given

12 - width

10 - height

8 - length

so all we have to do is plug in the values into the formula

volume = 12x10x8=960

so we can conclude that the volume of the ice cooler is 960

Answer:

12 times 8 equals 96 times 2 equals 192

10 times 8 equals 80 times 2 equals 160

10 times 12 equals 120 times 2 equals 240

240 plus 160 plus 192 equals 592
