Answer: 49x^14

Step-by-step explanation:

The expression that can be used to determine the number of years that it would take to have a balance of $600 is In2 ÷ In[tex]e^{0.005}[/tex].

When an amount is compounded continously, it means that both the amount deposited and the interest already accrued increases in value continously over a period of time.

Time = In(FV/PV) ÷ In([tex]e^{0.005}[/tex]

In2 ÷ In[tex]e^{0.005}[/tex]

Answer:

88 in³

Step-by-step explanation:

we are given that the volume V of a given mass of gas varies directly as the temperature T and inversely as the pressure P.

Condition-1:

The volume V of a given mass of gas varies directly as the temperature T , thus

[tex]V\propto T\\\implies V=kT[/tex]

Condition-1:

The volume V of a given mass of gas varies inversely as the pressure P, therefore,

[tex]V\propto 1/P\\\implies V=k\cdot 1/P[/tex]

combining 1 and 2 yields

[tex]V\propto k\cdot T/P[/tex]

Case-1:

To find:

Finding the constant of proportionality

[tex]341= k\cdot 310/10\\\implies k=341\times 10/310 \\ \implies \boxed{k=11}[/tex]

Case-1:

To find:

when:

Finding the volume:

[tex]V= 11\times 120/15\\\implies V=11\times 8 \\ \implies \boxed{V=88}[/tex]

Answer:

b=8.5cm

Step-by-step explanation:

tanx (this represents tan theta, it's just easier to type) is equal to 0.6 and since the tanx ratio is opp/adj, we know that opp/adj = 0.6

To find what b is (adjacent as it is adjacent to the angle being used and it is not the hypotenuse), we just have to rearrange.

0.6=5.1/adj

to solve for adj, we can switch 0.6 and adj. (This works because to get adj by itself on one side you would multiply it to the other side and then divide 0.6 from both sides --> simple algebra)

so then you have

adj=5.1/0.6

adj=8.5cm

(if you want to check your solution you can use pythagoeran theorem, a^2+b^2=c^2) and sub everything in and make sure all the numbers equal the right thing!

The system of equations can be used to find the roots of the considered  equation is y = 4+x^2 and y= x^3 + 2 + x

We do same operations on both the sides so that equality of both expressions doesn't get disturbed. Solving equations generally means finding the values of the variables used in it for which the considered equation is true.

Sometimes we can find such value, and sometimes it is not possible at all, or sometimes, there are infinite number of solutions.

For the given case, we are given with the equation [tex]4+x^2 = x^3 + 2 + x[/tex]

We can take two equations as:

[tex]y = 4+x^2 \\y= x^3 + 2 + x[/tex]

And when we will try to solve this system of equation, we will end up substituting the value of y in terms of x, and therefore, ending up on the same equation [tex]4+x^2 = x^3 + 2 + x[/tex]

x mL of the 35% saline solution contains 0.35x mL of salt.

10 mL of the 75% solution contains 0.75 • 10 mL = 7.5 mL of salt.

After mixing, the scientist would have a total volume of (x + 10) mL. We know its concentration is 40%, so it contains 0.40 (x + 10) mL of salt.

The total amount of salt before and after mixing must be the same, so

0.35x + 7.5 = 0.40 (x + 10)

Solve for x :

0.35x + 7.5 = 0.40x + 4.0

0.10x = 3.5

x = 35

The scientist used 35 mL of the 35% solution.

The value of the z is −2.1 then the probability P(z < −2.1) is 0.0179. Then the correct option is A.

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

If the value of the z is −2.1. Then the probability will be

P(z < −2.1) = 0.0179.

Answer:

Step-by-step explanation:

The equation for the base is that of a circle, so the cross sections will have a leg of length equal to the vertical distance between its halves.

x² + y² = 16   ⇒   y = ±√(16 - x²)

⇒   length = √(16 - x²) - (-√(16 - x²)) = 2 √(16 - x²)

Cross sections with thickness ∆x have a volume of

1/2 length² ∆x = 1/2 (2 √(16 - x²))² ∆x = (32 - 2x²) ∆x

since they are isosceles triangles and so their bases and heights are equal.

Then the total volume would be (D)
