Answer and Step-by-step explanation:

We first need to solve for x, and by doing that, we would need to multiply the length and width of the shaded box, have it be subtracted by the area of the inside box, and then equal it to the area.

(6x * x) -[(x + 4)(x - 1)] = 40.

$6x^2 - x^2 -3x + 4 = 40\\\\Simplify\\5x^2 - 3x + 4 = 40\\\\$

Subtract 40 from both sides of the equation.

$5x^2 - 3x - 36 = 0$

Now, factor the equation.

$(5x+12)(x-3)\\$

Solve for x.

x = $\frac{-12}{5}$

x = 3

If we were to plug in $\frac{-12}{5}$ for the width of the flower bed rectangle, we would get a negative side value, which we know isn't possible.

So, x is equal to 3.

Now, we plug 3 in for the x values.

3 + 4 = 7

3 - 1 = 2

Finally, we multiply the sides to get the area.

7 * 2 = 14.

The area of the flowerbed is 14 $m^2$ .

Which of the following functions gives the radius, r(v), of a conical artifact that is 20 inches tall as a function of its volum

nalin [4]

By calculus or elementary geometry, we know that the formula for the volume of a cone, given pi (the constant), its height h and its radius r is:
$V=pi*h*r^2/3$
Lets solve this relation for the radius:
$3V=pi*h*r^2
$
$\frac{3V}{pi*h} =r^2$
$\sqrt{\frac{3V}{pi*h}} = r$
Now we have found a general formula that gives us the radius of a cone, given its volume and height. We need only substitute height (20in) and pi=3.14 to get the numerical equation: r=0.2185* $\sqrt{V}$

The distribution of income tax refunds follow an approximate normal distribution with a mean of $7010 and a standard deviation o

Andrej [43]

Answer:

A refund must be above $7,139 before it is audited.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 7010, standard deviation = 43.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

The empirical rule is symmetric, which means that the lowest (100-99.7)/2 = 0.15% is at least 3 standard deviations below the mean, and the upper 0.15% is at least 3 standard deviations above the mean.

Use the Empirical Rule to determine approximately above what dollar value must a refund be before it is audited.

3 standard deviations above the mean, so:

7010 + 3*43 = 7139.

A refund must be above $7,139 before it is audited.

Could someone help me finding out the missing answers?

Tema [17]

Answer:

See below.

Step-by-step explanation:

The Slope of PQ is (v - z) / (w - x).

The slope of P'Q' =

(v + b) - (z + b)

--------------------- = (v - z) / (w - x)

(w + a - (x + a)

Both lines have a slope that is (v - z)/ (w - x).

So both lines are parallel.

Step-by-step explanation:

when doing 8% you go back 2 places so 0.08

34×0.08= 2.72

34+2.72= 36.72
