Answer:

The required inequality is $50w+100\geq 18000$

Step-by-step explanation:

Consider the provided information.

You get 100 points for playing the game. In addition, you get 50 points for each seven-letter word you make with the ten letters you receive.

Let w represents a seven letter word which Sal will need to make to break the record.

She gets 100 points for playing the game and 50 points for each seven-letter

Therefore the total points earned is: $50w+100$

Sal wants to break the record, and she needs 18,000 points or more.

Thus, the required inequality will be: $50w+100\geq 18000$

Hence, the required inequality is $50w+100\geq 18000$

Answer:

C. m<C = m<F

Step-by-step explanation:

this is because in their triangle names, they are in the same spot (third letter of the name)

if they are in the same spot, they <em>have</em> to be congruent

same goes for the other letters, <A has to be congruent to <D and <B has to be congruent to <E

Find the solution r(t)r(t) of the differential equation with the given initial condition: r′(t)=⟨sin9t,sin6t,9t⟩,r(0)=⟨4,6,3⟩

klemol [59]

$\mathbf r'(t)=\langle\sin9t,\sin6t,9t\rangle$

$\mathbf r(t)=\displaystyle\int\mathbf r'(t)\,\mathrm dt$

$\mathbf r(t)=\left\langle\displaystyle\int\sin9t\,\mathrm dt,\int\sin6t\,\mathrm dt,\int9t\,\mathrm dt\right\rangle$

$\displaystyle\int\sin9t\,\mathrm dt=\frac19\cos9t+C_1$

$\displaystyle\int\sin6t\,\mathrm dt=\frac16\cos6t+C_2$

$\displaystyle\int9t\,\mathrm dt=\frac92t^2+C_3$

With the initial condition $\mathbf r(0)=\langle4,6,3\rangle$ , we find

$\dfrac19\cos0+C_1=4\implies C_1=\dfrac{35}9$

$\dfrac16\cos0+C_2=6\implies C_2=\dfrac{35}6$

$\dfrac92\cdot0^2+C_3=3\implies C_3=3$

So the particular solution to the IVP is

$\mathbf r(t)=\left\langle\dfrac19\cos9t+\dfrac{35}9,\dfrac16\cos6t+\dfrac{35}6,\dfrac92t^2+3\right\rangle$

3(1)+2(_)=6<br><br> plz help on filling in the blank

TEA [102]

Answer:

x = 3/2

Step-by-step explanation:

Let's solve your equation step-by-step.

(3)(1)+2x=6

Step 1: Simplify both sides of the equation.

(3)(1)+2x=6

3+2x=6

2x+3=6

Step 2: Subtract 3 from both sides.

2x+3−3=6−3

2x=3

Step 3: Divide both sides by 2.

2x/2 3/2

x = 3/2

Hope this helps :)
