Answer: (P-40)/5 = a

Step-by-step explanation:

P = 5(a+8)

P = 5a + 40

P - 40 = 5a

(P-40)/5 = a

It seems like σ(t) is the positive function of the particle. Compute its acceleration by differentiating this function twice.

σ(t) = {t ², sin(t ), cos(t )}

σ'(t) = {2t, cos(t ), -sin(t )}

σ''(t) = {2, -sin(t ), -cos(t )}

When t = 0, the acceleration on the particle is

σ'' (0) = {2, -sin(0), -cos(0)} = {2, 0, -1}

Then the force acting on the particle at time t = 0 is

F = {2m, 0, -m}

by Newton's second law.

Answer:

350 will be your answer :)

Step-by-step explanation:

so i did 70 divided by 2 because 140 divided by 70 = 2

and 70 divded by 2 IS 35!

But wait that isn't what it's asking for right?

then i did 35 TIMES 10 cuz that's what it;s asking for

i got 350 and so should you so in conclusion 350 is your answer

Hopefully this helped!

Answer:

They will drive 350mi in 10hrs.

Step-by-step explanation:

If they go 70 miles in 2hrs then that means they go 35mi in 1hr. So multiply 35 by 10 and you get 350mi.

Answer:

x=4.5

Step-by-step explanation:

divided both sides by 2, your equation is now x=4.5

Answer:

x < -8.5

Step-by-step explanation:

-46 - 8x > 22

-8x > 68 -- when you divide by a negative number in an inequality, you flip the inequality sign

Therefore, x < -8.5

Answer:

The upper bound for the total mass of the 50 parcels is 850 kilograms.

Step-by-step explanation:

From statement we infer that upper bound is represented by the 50 identical parcels completely full. Then, the upper bound is the product of number parcels and maximum capacity of each parcel:

[tex]m_{UP} = (50\,parcel)\cdot \left(17\,\frac{kg}{parcel} \right)[/tex]

[tex]m_{UP} = 850\,kg[/tex]

The upper bound for the total mass of the 50 parcels is 850 kilograms.

Answer:

a. The slope m is 0.02

b. The initial value b is 250

c. y = 0.02x + 250

d. His weekly income is $262  if the sales were $600.00

Step-by-step explanation:

the form of the linear equation is y = m x + b, where

∵ A real estate sales agent receives a salary of $250 per week

→ This is a fixed amount every week

∴ b = 250

∵ They give a commission of 2% of sales

→ This value depends on the sales (rate of change)

∵ 2% = 2 ÷ 100 = 0.02

∴ m = 0.02

a. The slope m is 0.02

b. The initial value b is 250

∵ y represents the weekly income

∵ x represents the sales

∵ m = 0.02 and b = 250

∴ The equation is y = 0.02x + 250

c. y = 0.02x + 250

∵ The sales were $600.00

∴ x = 600

→ Substitute it in the equation to find y

∵ y = 0.02(600) + 250

∴ y = 12 + 250

∴ y = 262

d. His weekly income is $262  if the sales were $600.00

Answer:

The 50th score is 46.

Step-by-step explanation:

Given that

[tex]a_{50} = 26.4\\a_{49} = 26\\n_1 = 50\\n_2 = 49[/tex]

In order to find the 50th score we have to find sum of 49 values and 50 values and then subtract them.

Average is given by the formula:

[tex]Average = \frac{Sum}{Number\ of\ values}\\[/tex]

Using this formula, we can calculate sum for both averages

So,

[tex]a_{50} = \frac{s_{50}}{n_1}\\26.4 = \frac{s_{50}}{50}\\26.4*50 = s_{50}\\s_{50} = 1320[/tex]

And

[tex]a_{49} = \frac{s_{49}}{n_2}\\26.4 = \frac{s_{49}}{49}\\26*49 = s_{49}\\s_{49} = 1274[/tex]

Now for the 50th score,

[tex]50th\ score = s_{50} - s_{49} = 1320-1274 = 46[/tex]

Hence,

The 50th score is 46.

Answer:

(1) & (3)

Step-by-step explanation:

Given

List of options

Required

Select which is equal to 60 when h = 3

To do this, we simply substitute 3 for h in all of the options.

1.

[tex](h + 1)^3 - 4[/tex]

[tex](3 + 1)^3 - 4[/tex]

[tex]4^3 - 4[/tex]

[tex]64 - 4[/tex]

[tex]60[/tex]

Hence:

[tex](h + 1)^3 - 4= 60[/tex]

2.

[tex](4h)^2 + 36[/tex]

[tex](4*3)^2 + 36[/tex]

[tex](12)^2 + 36[/tex]

[tex]144 + 36[/tex]

[tex]180[/tex]

Hence:

[tex](4h)^2 + 36=180[/tex]

3.

[tex]4h^2 + 24[/tex]

[tex]4*3^2 + 24[/tex]

[tex]4 * 9 + 24[/tex]

[tex]36 + 24[/tex]

[tex]60[/tex]

Hence:

[tex]4h^2 + 24 = 60[/tex]

Answer:

4/5

Step-by-step explanation:

Answer:

So just as a fraction of 3/30 can be simplified to 1/10, a ratio of 3:30 (or 4:40, 5:50, 6:60 and so on) can be simplified to 1:10.

Step-by-step explanation:

Answer:

1. 2:20

2. 3:30

3. 4:40

Step-by-step explanation:

1/10 can be written as a ratio like so - 1:10

Now we just have to change both numbers by multiplying or dividing by the same amount to get 3 equivalent ratios.

We can multiply both numbers by 2 to get - 2:20

Or we can multiply both numbers by 3 to get - 3:30

And, we can also multiply both numbers by 4 to get - 4:40

These are 3 possibilities of many possibilities

Answer:

The correct answer is:

Option A: A 10x — 15000 ≥ 50000

Step-by-step explanation:

Given that the total cost of manufacturing by the company is $15000.

Let x be the number of gallons the company sells.

It is also mentioned that the company earns $10 on each gallon.

So the total profit will be the the difference of the selling cost of gallons and manufacturing cost

Mathematically,

[tex]10x-15000[/tex]

Now it is mentioned that the profit should be at least 50000 dollars which means the profit can be minimally 50000 and also can be greater than it so

[tex]10x-15000 \geq 50000[/tex]

The number of gallons can be found by solving the obtained inequality.

Hence,

The correct answer is:

Option A: A 10x — 15000 ≥ 50000

Answer:

Sue collected 1/2 bags of clothes.

Step-by-step explanation:

Fractions

Let's solve the problem from end to beginning.

Martin collected 2 1/2 bags of clothes for a clothing drive. This mixed fraction can be expressed as:

[tex]2\frac{1}{2}= 2+\frac{1}{2}=\frac{5}{2}[/tex]

Sue collected 1/5 as many clothes as Martin did. This means she collected:

[tex]\frac{1}{5}\cdot \frac{5}{2}[/tex]

Multiplying:

[tex]\frac{1}{5}\cdot \frac{5}{2}=\frac{1}{2}[/tex]

Sue collected 1/2 bags of clothes.

Answer:

No
