Answer:

B 1 3/4 inches

Step-by-step explanation:

The tallest flower is 8 1/4 inches

The shortest flower is 6 1/2 inches

The difference is

8 1/4 - 6 1/2

Get a common denominator

8 1/4 - 6 1/2*2/2

8 1/4 - 6 2/4

Borrow 1 ( which is equal to 4/4) from the 8

7 +4/4 +1/4 - 6 2/4

7 5/4 - 6 2/4

1 3/4 inches

Which linear function shows the same relationship as the table below?

shusha [124]

Answer:

Step-by-step explanation:

The simplest way to solve this problem is plugging the X value back into each equation. C (y=4x+1) is the only equation that works for each set. You plug in 1 for X, you get 5 for Y. You plug in 4 for X, you get 17 for Y. Etc.

Binomial (x - 6) and trinomial (-2x2 + x + 9) are the factors of which of the

djyliett [7]

Answer:

Option (3)

Step-by-step explanation:

If binomial (x - 6) and trinomial (-2x² + x + 9) are the factors of a polynomial then their multiplication will be equal to the polynomial.

(x - 6)(-2x² + x + 9) = x(-2x² + x + 9) - 6(-2x² + x + 9)

= -2x³ + x² + 9x + 12x² - 6x - 54

= -2x³ + 13x² + 3x - 54

Therefore, Option (3) will be the correct option.

How do you integrate arctan(x dx? i think that if you simplify the integral you get:?

Temka [501]

Integration by parts will help here. Letting $u=\arctan x$ and $\mathrm dv=\mathrm dx$ , you end up with $\mathrm du=\dfrac{\mathrm dx}{1+x^2}$ and $v=x$ . Now

$\displaystyle\int\arctan x\,\mathrm dx=uv-\int v\,\mathrm du$
$\displaystyle\int\arctan x\,\mathrm dx=x\arctan x-\int\frac x{1+x^2}\,\mathrm dx$

For the remaining integral, setting $y=1+x^2$ gives $\dfrac{\mathrm dy}2=x\,\mathrm dx$ , so

$\displaystyle\int\frac x{1+x^2}\,\mathrm dx=\frac12\int\frac{\mathrm dy}y=\frac12\ln|y|+C=\frac12\ln(1+x^2)+C$

Putting everything together, you end up with

$\displaystyle\int\arctan x\,\mathrm dx=x\arctan x-\frac12\ln(1+x^2)+C$

Please help me with this question, thanks.

Answer:

2.48×10^13 miles

Step-by-step explanation:

There are about (365.25 days)(86400 seconds/day) = 31,557,600 seconds in one year. There are 1609.344 meters in one mile. So, the conversion can be written as ...

(4.22 ly) (3×10^8 m/s) (3.15576×10^7 s/yr) / (1.609344×10^3 m/mi)

= 4.22×3×3.15576/1.609344×10^(8+7-3) mi

≈ 24.8×10^12 mi

4.22 light years is about 2.48×10^13 miles
