Answer:

-0.76

Step-by-step explanation:

this is pretty simple subtraction but you just take 14.36 and subtract it by 15.12 and you know it will be a negative number because 15.12 is bigger than 14.36 and so your answer is -0.76

The line 2x +3y = 1 is tangent to 4x^2 -9y^2 = 19

:

Solve the linear equation for y

:

1) y = -2x/3 +1/3

:

substitute for y in the equation of the hyperbole

:

4x^2 -9(-2x/3 +1/3)^2 = 19

Given:

The word is "CALCULATOR."​

To find:

The number of distinct permutations.

Solution:

In the word "CALCULATOR",

The number of letters = 10

In which, we have 2 C, A, L and 1 U, T, O, R.

We know that,

[tex]^nC_r=\dfrac{n!}{(n-r)!}[/tex]

[tex]^nC_n=\dfrac{n!}{(n-n)!}=n![/tex]

To find the number of distinct permutations of the given word need to divide permutation of all letter by the permutations of repeated letters.

[tex]\text{Total ways}=\dfrac{^{10}C_{10}}{^2C_2\ ^2C_2\ ^2C_2\ ^1C_1\ ^1C_1\ ^1C_1\ ^1C_1}[/tex]

[tex]\text{Total ways}=\dfrac{10!}{2!2!2!1!1!1!1!}[/tex]

[tex]\text{Total ways}=\dfrac{10\times 9\times 8\times 7\times 6\times 5\times 4\times 3\times 2\times 1}{2\times 2\times 2\times 1\times 1\times 1\times 1}[/tex]

[tex]\text{Total ways}=453600[/tex]

Therefore, the number of distinct permutations of the word "CALCULATOR" is 453600.

Number of distinct permutation of the word "CALCULATOR." is 453600

How to solve this problem?

Total number of words in "CALCULATOR" is 10

we find out the words that are repeating

A is repeating twice (2)

C is repeating twice (2)

L is repeating twice (2)

Number of permutations = number of letters !/ repeating letters!

Number of distinct permutation =

[tex]\frac{10!}{2!2!2!} \\\frac{10\cdot9\cdot8\cdot7\cdot6\cdot5\cdot4\cdot3\cdot2\cdot1}{2\cdot2\cdot2} \\453600[/tex]

Number of distinct permutation of the word "CALCULATOR." is 453600

Step-by-step explanation:

the answer is 7.7

there will be $9350 in the account after 7 years and 9 months.

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. A = P(1 + r/n)^nt, where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, is the formula for compound interest.

Given, If you deposit $5000 into an account paying 8.25% annual interest compounded semiannually.

To calculate time until there is $9350 in the account.

So,

From the general formula of Compound interest:

A = P(1 + r/n)^nt,

where P is the principal balance,

r is the interest rate,

n is the number of times interest is compounded annually,

and t is the number of years,

In our case,

A = 9350

p = 5000

r = 8.25

n = 2

Thus,

9350 = 5000(1 + 8.25/2%)^2*t

(1 + 8.25/2%)^2*t = 9350/5000

t = 7 years 9 months

Therefore, there will be $9350 in the account after 7 years and 9 months.

Answer:

y = 8

x = 8√5

z = 4√5

Step-by-step explanation:

Using the formula (which is a geometric mean):

a        y

---- = -----

x        a

Where a is the altitude (y), x is a projection (16), and y is the other projection (4):

y        4

---- = -----

16       y

Cross multiply:

y² = 16 (4)

y² = 64

√y² = √64

y = 8

To find x and z, use the Pythagorean Theorem:

16² + y² = x²

256 + 8² = x²

256 + 64 = x²

320 = x²

√320 = √x²

√64√5 = √x²

8√5 = x

x = 8√5

4² + y² = z²

16 + 64 = z²

80 = z²

√80 = √z²

√16√5 = √z²

4√5 = z

z = 4√5

Answer:

110 grams

Step-by-step explanation:

CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).

So first finding the mass of 1 molecule of CO2 which is equals to

= mass of 1 carbon atom + masses of 2 oxygen atom, we get

= 12+(16*2)= 12+32= 44 a.m.u.

Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )

1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams

So our answer is 110 grams.

Answer:

5.2 cubic ft

Step-by-step explanation:

took the test

The volume of given cone is 5.23 cubic feet.

Volume is the measure of the capacity that an object holds.

[tex]v = \frac{1}{3} \pi r^{2} h[/tex]

where,

v is the volume of cone

r is the radius of cone

h is the height of cone

According to the question we have

Diameter of cone is 2ft

⇒ radius of the cone = [tex]\frac{2}{2} = 1 feet[/tex]

Height of the cone is 5ft.

Therefore,

The volume of the cone  = [tex]\frac{1}{3}(1)\pi( 1)^{2} (5)[/tex]

Volume of cone = [tex]\frac{1}{3} (3.14)(1)(5) = 5.23 cubic feet[/tex]

Hence, hence the volume of given cone is 5.23 cubic feet.

y=e^x+3.

The given graph of the function y = e^x

he transformation occur when we add c to the parent function y = e^x giving us a vertical shift c unit in the same direction as the sign.

The y axis of a coordinate plane is the vertical axis. When a function shifts vertically, the value of y changes.

The given parent function: y = e^x,

we can now graph the vertical shift alongside i.e, c=3

Then, the upward shift function is, y = e^x + c

Substitute the value of c=3,

then, the transformed equation becomes, y = e^x + 3

as it goes through (0,4).

∴The equation y = e^x + 3 represents the transformed function.

y=e^x+3.
