Question 1: The Magnolia trees purchased for planting at the school are 3 feet tall. Research shows that these types of trees grow at an average of 3/4 foot per year

) Some students misunderstood question #1 and wrote the following equations in point-slope form:
a) y − 3 = 3/4(x-0)
b) y - 6 = 3/4(x-4)
c) y - 4.5 = 3/4(x-2)
d) y - 12 = 3/4(x-12)
(e) y - 15= 3/4(x-15)

Is this equation okay to use for the height of the trees in this problem?

There is one equation that is incorrect.... determine which one? why is it incorrectly?

Creat two new equations written in point slope form​

Answers

The equation in option e) is not correct because it would not give correct height of the trees in this problem

How to write equation in slope-point form?

Since the Magnolia trees are 3 feet tall and grow at an average of 3/4 foot per year.

If x is the number of years and y is the height. we can write:

y = 3/4(x) + 3

The slope-point equation of a line is given as:

y-y1 = m(x−x1)

y = 3/4(x) + 3 in slope-point  form is:

y = 3/4(x) + 3

y-3 =  3/4(x-0)

This means option a) is correct

Yes, this equation is okay to use for the height of the trees in this problem

b) y - 6 = 3/4(x-4)

y - 6 = 3/4(x-4)

y - 6 = 3/4(x)- 3

y - 6 + 3 = 3/4(x)

y - 3 = 3/4(x)

This is correct

c) y - 4.5 = 3/4(x-2)

y - 4.5 = 3/4(x-2)

y - 4.5 = 3/4(x)- 1.5

y - 4.5 + 1.5 = 3/4(x)

y - 3 = 3/4(x)

This is correct

d) y - 12 = 3/4(x-12)

y - 12 = 3/4(x-12)

y - 12 = 3/4(x) - 9

y - 12 + 9 = 3/4(x)

y - 3 = 3/4(x)

This is correct

(e) y - 15= 3/4(x-15)

y - 15= 3/4(x-15)

y - 15= 3/4(x)-11.25

y - 15 + 11.25= 3/4(x)

y - 3.75 = 3/4(x)

This is not correct because it does not reflect the given information

Shift A: {77, 91, 82, 68, 75, 72, 85, 65, 70, 79, 94, 86}

Number of data in shift A = 12

Mean = (77 + 91 + 82 + 68 + 75 + 72 + 85 + 65 + 70 + 79 + 94 + 86) / 12

         = 944 / 12

         = 78.67

Shift B: {68, 93, 53, 100, 77, 86, 91, 88, 72, 74, 66, 82}

Number of data in shift B = 12

Mean = (68 + 93 + 53 + 100 + 77 + 86 + 91 + 88 + 72 + 74 + 66 + 82) / 12

         = 950 / 12

         = 79.17

What is meant by chain rule?

To determine the derivative of a composite function in differential calculus, apply the chain rule formula. If y = f(g(x)), then according to the chain rule, the instantaneous rates of change of the functions f and g with respect to x produce the instantaneous rate of change of f with respect to x.

A composition of functions, such as the composition of the functions f and g, f(g(x)), can be used to determine the derivative using the chain rule.

Let us set up the following variables:

R, Radius of conical cup (cm) = 30 cm

H, Height of the conical cup (cm) = 10 cm

Our aim is to find dV/dt when h = 9 and we are given dh/dt = 2

By similar triangles we have

r : h = R : H

r/h = 30/10

⇒ r = 3h

The volume of a cone is 1/3π r²h, So:

V = 1/3π r²h

simplifying the equation, we get

= 1/3π (3h²)h

= 1/3π 9h²h

= 3π h³

Differentiating wrt h we get:

dV/dh = 9π h²

Applying the chain rule we have:

dV/dt = (dV/dh)(dh/dt)

= 9π h² × 2

= 18π h²

If h = 9 then

[tex]$\left[\frac{d V}{d t}\right]_{h=9}=18 \pi\left(9^2\right)=1458 \pi \mathrm{cm}^3 s^{-1}$$[/tex].

Therefore, the rate exists water being poured into the cup when the water level 9 cm exists [tex]$$1458 \pi \mathrm{cm}^3 s^{-1}$$[/tex].

Is Amu equal to Avogadro's number?

Answers

Therefore, amu (atomic mass unit) and Avogadro's number are not the same things.

Define amu (atomic mass unit).

A unit of measurement for atomic and molecular weight is the atomic mass unit (amu).

What is molecular weight?

Molecular weight, commonly known as molecular mass, is the mass of a substance's molecules, calculated using the atomic weight of carbon-12, which is 12.

No, amu and Avogadro's numbers are not the same things because An atomic mass unit (amu) is a unit of measurement for atomic and molecular weight. It is defined as one twelfth of the mass of a neutral atom of carbon-12. It is commonly used in chemistry to express the masses of atoms and molecules While Avogadro's number (N) is a fundamental constant of nature that relates the number of atoms or molecules in a sample to the mass of that sample. It is defined as the number of atoms or molecules in one mole of a substance. It is approximately 6.022 x 10^23 atoms or molecules per mole.

So, amu is a unit of measurement for atomic and molecular weight, while Avogadro's number is a constant that relates the number of atoms or molecules in a sample to the mass of that sample.

Write the equation in standard form with integer coefficients. 0.5x - 2y - 0.75 = 0, y = - 3 x - 5

Answers

Answer:

50x - 200y = 75

3x + y = -5

Step-by-step explanation:

Standard form of a line

Ax + By = C

0.5x +-2y -0.75  Multiply through by 100

50x - 200 - 75 = 0  Add 75 to both sides

50x - 200y = 75

y = -3x - 5  Add 3x to both sides

3x + y = -5

A person places $51200 in an investment account earning an annual rate of 5. 4%, compounded continuously. Using the formula V = Pe^{rt}V=Pe

rt

, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 6 years

Answers

The amount of money in the account after 6 years is $68,847.56

To solve this problem, you can use the formula for compound interest,

V = Pe^(rt)

where V is the final value of the account, P is the initial principal, r is the annual interest rate (expressed as a decimal), and t is the number of years the money is invested.

The formula for compound interest, V = Pe^(rt) is used to calculate the future value of an investment. It takes into account the effect of compounding, which means that interest is earned not only on the initial investment but also on the accumulated interest over time.

Plugging in the given values, we have

V = 51200e^(0.0546) = 51200e^0.324. e^0.324 is approximately 1.38, so the final value of the account is 512001.38 = $68,847.56
