Answer: The answer is 6.28571 . . ..

Step-by-step explanation: We are given ti find the value of twice of pi into the palette.

We are familiar with the irrational number pi. It is defined as the ration of circumference of a circle to the diameter of the circle and its value is 22/7 or 3.14159 . . ..

Therefore, the value of 2 pi can be calculated as follows.

$2\pi=2\times\dfrac{22}{7}=\dfrac{44}{7}=6.28571~.~.~..$

Thus, the value of 2pi is 6.28571 . . ..

Two cubes and one bean are balanced by eight toothpicks. One cube is balanced by one bean and one toothpick. How many toothpicks

Art [367]

Answer:

Three toothpicks balance one cube.

Step-by-step explanation:

Let B, T and C stand for bean, toothpick and cube respectively.

If two cubes and one bean are balanced by eight toothpick, this means:

2C + B = 8T

If one cube is balanced by one bean and one toothpick, this means:

B + T = C. Therefore, we have two equations:

2C + B = 8T

B + T = C

Multiplying the second equation by 2, we have:

2B + 2T = 2C

Rearranging the resulting equation, we have:

-2C + 2B = -2T. Therefore, we have:

2C + B = 8T

-2C + 2B = -2T

Adding the last two equations, we have:

3B = 6T

Divide both sides by 3, we have:

B = 2T

Hence, two toothpicks balances one bean.

From the question, we are told

B + T = C

Substituting B = 2T, we have:

2T + T = C

3T = C.

Therefore, three toothpicks balance one cube.

$\huge\text{Hey there!}$

$\mathsf{\dfrac{2}{5}x-7=11}$

$\large\textsf{ADD 7 to BOTH SIDES}$

$\mathsf{\dfrac{2}{5}x -7+7=11+7}$

$\large\textsf{CANCEL out: -7 + 7 because that gives you 0}$

$\large\textsf{KEEP: 11 + 7 because it helps you solve for your x-value}$

$\mathsf{11 + 7 = 18}$

$\large\text{New EQUATION: }\mathsf{\dfrac{2}{5}x = 18}$

$\large\textsf{MULTIPLY }\mathsf{\dfrac{5}{2}}\large\textsf{ to BOTH SIDES }$

$\mathsf{\dfrac{2}{5}x \times \dfrac{5}{2}=\dfrac{5}{2}\times18}$

If the APY of a savings account is 3.9%, and if the principal in the savings account is $3700 for an entire year, what will be t

joja [24]

Answer:

Option B. $\$3,844.30$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=1\ years\\ P=\$3,700\\r=0.039$

substitute in the formula above

$A=\$3,700(1+0.039*1)=\$3,844.30$

) For which values of x is f '(x) zero? (Enter your answers as a comma-separated list.) x = (No Response) For which values of x

grigory [225]

Answer:

Check below, please

Step-by-step explanation:

Step-by-step explanation:

1.For which values of x is f '(x) zero? (Enter your answers as a comma-separated list.)

When the derivative of a function is equal to zero, then it occurs when we have either a local minimum or a local maximum point. So for our x-coordinates we can say

$f'(x)=0\: at \:x=2, and\: x=-2$

2. For which values of x is f '(x) positive?

Whenever we have

$f'(x)>0$

then function is increasing. Since if we could start tracing tangent lines over that graph, those tangent lines would point up.

$f'(x)>0 \:at [-4,-2) \:and\:(2, \infty)$

3. For which values of x is f '(x) negative?

On the other hand, every time the function is decreasing its derivative would be negative. The opposite case of the previous explanation. So

$f'(x)$

4.What do these values mean?

$f(x) \:is \:increasing\:when\:f'(x) >0\\\\f(x)\:is\:decreasing\:when f'(x)$

5.(b) For which values of x is f ''(x) zero?

In its inflection points, i.e. when the concavity of the curve changes. Since the function was not provided. There's no way to be precise, but roughly

at x=-4 and x=4

A . it is increasing and linear

Paha777 [63]

Answer:

The answer is B.

Step-by-step explanation:

From the interval -6 < x < 0, the line is straight which is linear equation. The line shows its going down so it will be decreasing gradient.
