Solve | 2x - 6 | = |x| by graphing

Answer:

A) r=∛(6v)/[tex]\pi[/tex]

Step-by-step explanation:

v=1/6[tex]\pi[/tex]r³

v÷1/6=[tex]\pi[/tex]r³

(when dividing by a fraction, invert and multiply)

6v=[tex]\pi[/tex]r³

6v÷[tex]\pi[/tex]=r³

(6v)/[tex]\pi[/tex]=r³

take the cube root of both sides

∛(6v)/[tex]\pi[/tex]=∛r³

∛(6v)/[tex]\pi[/tex]=r

Answer:

the value will fall below $3000 in the 7 th year because :

Step-by-step explanation:

15% of 13500 is 2025

On subtracting 2025 from 13500 every time we can see that the value keeps dropping.

So, we will get $3375 in year 6 and in year 7 we will get $1350 by subtracting 2025 from 3375.

Hence we will get 1350 at the 7th year.

After 6.79 years, the car's value will drop below $3,000.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Now, The following is a representation of the exponential function to model the car's value:

V(t) = 13500 (1 - 0.15)ⁿ

V(t) = 13500(0.85)ⁿ

Here, V(t) denotes the car's worth at time n in years, and 0.85 denotes the annual depreciation rate of 15%.

Hence, The following equation can be put up to determine when the car's value will drop below $3,000:

13500(0.85)ⁿ = 3000

As we solve for n, we obtain:

n = (log(3000/13500)/log(0.85))

n = 6.79

So, after roughly 6.79 years, the car's value will drop below $3,000.

Step-by-step explanation:

Sorry if wrong i think it is this

Answer:

28 yards

Step-by-step explanation:

this is a right angled triangle

this question will be solved by Pythagoras theorem

which states square of hypotenuse=square of legs

so 35= 21sqr+b sqr

1225=441+b sqr

b sqr= 1225-441

b sqr=784

b= sqr root of 784

= 28 yards

perimeter=1/2multiplied to base to height

=(21*35)/2

Answer:

Even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.

Step-by-step explanation:

Given that you invested $ 3000 between two accounts paying 4% and 8% annual interest respectively, to determine how much was invested at each rate if the total interest eamed for the year was $ 520, the following calculation must be performed:

3000 x 0.04 + 0 x 0.08 = 120

1500 x 0.04 + 1500 x 0.08 = 180

3000 x 0.08 + 0 x 0.04 = 240

Thus, as can be seen, even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.

Given:

The probability of landing A is 0.70.

The probability of landing B is 0.60.

The probability of landing both is 0.50.

To find:

The probability of landing A given it lands B.

Solution:

We have,

[tex]P(A) = 0.70[/tex]

[tex]P(B) = 0.60[/tex]

[tex]P(A\cap B) = 0.50[/tex]

The probability of landing A given it lands B is

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{P(A\cap B)}{P(B)}[/tex]

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{0.50}{0.60}[/tex]

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{5}{6}[/tex]

[tex]P\left(\dfrac{A}{B}\right)=0.8333...[/tex]

[tex]P\left(\dfrac{A}{B}\right)\approx 0.83[/tex]

Therefore, the probability of landing A given it lands B is about 0.83.

Answer:

The measure of angle BED is 82°

Step-by-step explanation:

The angles of a triangle, all together, equal 180°.

Angle B and D are the same and angle B is 49° so angle D is also 49°.

You add 49 to 49 which equals 98, and subtract 98 from 180 to find out what angle E is.

Answer:

The answer is "0.0547".

Step-by-step explanation:

[tex]P(Correct) = 0.50\\\\n = 10\\\\x = 8[/tex]

Using the binomial distribution:

[tex]\to P(x,n) = n_{C}_x \times p^x \times (1-p)^{(n-1)}\\\\\to P(x \geq 8) = 1 - P( \leq 7)[/tex]

Calculating the excel formula:

[tex]=BINOM.DIST(7,10,0.50,TRUE)[/tex]

[tex]\to P(x \geq 8) = 1 - 0.9453\\\\ \to P(x \geq 8) = 0.0547[/tex]

Answer:

If its radius is 9 cm, it’s circumference would be two times radius times pi equal to 18 pi. Also its area is pi R squared which is equal to 81 pi.  Circumference = 18 pi  Area = 81 pi  Area is 4.5 times greater than the circumference. The answer is C.

Answer:

Those two quantities are incommensurate, you can't compare them. The circumference is a length and the area is an area. There is no way to compare the two.

Now if you're talking about the formula Area = circumference squared over 4 times Pi, and if you're just going to go with the numerical values of Area and circumference, then there is an answer.
