Answer:

(0, 1/3)

Step-by-step explanation:

choose any value for x, x = 0

then find the corresponding y value by plugging in x to equation,

3(0) + 6y =2

6y = 2

y = 2/6 = 1/3

thus point on this line is (0, 1/3)

Answer:

336 cubic cm

Step-by-step explanation:

Volume of cone + (Volume of Sphere/2)

V (cone) = (π[tex]r^{2}[/tex]h)/3

               = π[tex]4^{2}[/tex](12) ÷ 3

               = 64π  ≈ 201 cm

V (sphere) = 4/3π[tex]r^{3}[/tex]/2

               = [4/3π(4^3)] ÷ 2

               = (256π/3) ÷ 2

               ≈ 43π ≈ 135

Answer:

T = 21.98

Step-by-step explanation:

T = pi (R²-r²)

T = 3.14 x (4² - 3²) = 3.14 x (16 - 9) = 3.14 x 7 = 21.98

Answer: Q(t) = 410*(5)^(2t) = 410*(5^2)^t = 410*(25)^t

Step-by-step explanation:

We start with the equation:

Q(t) = 410*(5)^(2t)

And we want to rewrite this in the form:

Q(t) = a*b^t

To do this, we need to use the property:

(a^x)^y = a^(x*y)

Using this, we can rewrite:

Q(t) = 410*(5)^(2t) = 410*(5^2)^t = 410*(25)^t

And this is the form that we wanted:

Answer:

13120(16)^t

Step-by-step explanation:

The number of views on a viral video can be modeled by the function Q(t)=820(4)^{2t+2}.Q(t)=820(4)

Step-by-step explanation:

please mark brainliest i need it to rank up

Answer:

6.2x10∧3

Step-by-step explanation:

For scientific notation you can only be in the one digits, so you have to move the decimal three place to the left ( I'm sorry if this doesn't explain it well enough)

Answer:

1. Deep Ocean Currents

2. Deep Ocean Currents

Step-by-step explanation:

Answer:

Option C is correct

Step-by-step explanation:

Here, we want to find which of the equations in the option is same as that in the question

The rule to use is that;

Loga B^y

= ylogaB

And also:

loga(X/Y) = logaX-logaY

Now, we start by applying these equations;

T(a) = log5 (a/3500)^1/0.03

T(a) = 1/0.03log5(a/3500)

T(a) = 1/0.03log5a - 1/0.03log53500

This makes the third option correct

Answer:

Step-by-step explanation:

Subtracting the remainder from the original polynomial gives a polynomial that has (x^2 -1) as a factor. Dividing, we find the quotient and remainder to be ...

  (x^5 +ax^3 +bx^2 +x -1)/(x^2 -1) = (x^3 +(1+a)x +b) remainder (2+a)x +(b -1)

Since we want the remainder to be zero, we require ...

  2+a = 0   ⇒   a = -2

  b -1 = 0   ⇒   b = 1

_____

The attachment shows the division as given in the problem statement (with the given remainder expression).

Answer:

the 17 books should be put in each pile

Step-by-step explanation:

The computation of the number of books in each pile is shown below:

Given that

There are 119 books

And there are 7 piles

So, the number of books in each pile is

= 119 books ÷ 7 piles

= 17 books

Hence, the 17 books should be put in each pile

So the same is to be conisdered and relevant too

Answer:

B. 7[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1/2−x+3/2=x−4

1/2+−x+3/2=x+−4

(−x)+(1/2+3/2)=x−4(Combine Like Terms)

−x+2=x−4

−x+2=x−4

Step 2: Subtract x from both sides.

−x+2−x=x−4−x

−2x+2=−4

Step 3: Subtract 2 from both sides.

−2x+2−2=−4−2

−2x=−6

Step 4: Divide both sides by -2.

−2x/−2=−6/−2

x=3

Answer:

670.21ft^3

Step-by-step explanation:

Volume of a cylinder=pi*r^2*h

Radius=8/2=4

Height=12

Volume=603.19

Volume of a cone=pi*r^2*(h/3)

radius=8/2=4

Hight=16-12=4

Volume=67.02

603.19+67.02=670.21ft^3

Answer:

18 pounds

Step-by-step explanation:

Here is the full question :

Cecile packages snack mix at a health food store.

She uses 1/3 of her supply of sunflower seeds to make a salted snack mix and 2/9 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?

Let x = Cecile's supply

1/3 of x = 1/3x

2/9 of x = 2/9x

1/3x + 2/9x = 10

adding the fraction together gives 5/9

5/9 x = 10

solve for x = 18 pounds
