Ryker is given the graph of the function

1 answer:

8 0

You can just set y=0 and solve for x. when you do this you should get 1/2x^2=4
x^2=8
x=2.8 and -2.8 ( you have both a positive number and negative number since (-2.8)^2=(2.8)^2 =8
I hope this helps

Find the solution r(t)r(t) of the differential equation with the given initial condition: r′(t)=⟨sin4t,sin7t,9t⟩,r(0)=⟨9,8,3⟩

Makovka662 [10]

$\mathbf r'(t)=\langle\sin4t,\sin7t,9t\rangle$
$\implies\mathbf r(t)=\displaystyle\int\mathbf r'(t)\,\mathrm dt$
$\mathbf r(t)=\displaystyle\left\langle\int\sin4t\,\mathrm dt,\int\sin7t\,\mathrm dt,\int9t\,\mathrm dt\right\rangle$
$\mathbf r(t)=\left\langle-\dfrac14\cos4t+C_1,-\dfrac17\cos7t+C_2,-\dfrac92t^2+C_3\right\rangle$

With $\mathbf r(0)=\langle9,8,3\rangle$ , we have

$\langle9,8,3\rangle=\left\langle-\dfrac14+C_1,-\dfrac17+C_2,C_3\right\rangle$
$\implies C_1=\dfrac{37}4,C_2=\dfrac{57}7,C_3=8$
$\implies\mathbf r(t)=\left\langle-\dfrac14\cos4t+\dfrac{37}4,-\dfrac17\cos7t+\dfrac{57}7,-\dfrac92t^2+8\right\rangle$

Answer:

1/6

Step-by-step explanation:

There are 4 different types of clothing

We want socks

P(socks) = 1/4

Now we have 3 different colors, 2 of which are not blue

P(not blue) =2/3

P(socks that are not blue) = 1/4*2/3 = 2/12 = 1/6

Decrease 960 ML by 33 and one-third%

AnnZ [28]

To do this, first, find the decimal of 1/3. You will divide 1 by 3. This equals .333333333(goes on forever). Put a repeating bar over the first 3 to show that it goes on forever (put this: - over the .3) Now divide to find out how much you will need to subtract by. 960*33.3(with - over .3)=28.8. Subtract 28.8 from 960 (960-28.8=931.2) 931.2 is the answer.
