The lengths of sides of a 30°-60°-90° triangle have the ratio 1 : √3 : 2. Multiplying these values by 5 tells you the sides have the lengths 5 : 5√3 : 10.

The length x of the middle-length side is ...

A school club is raising money for a trip, and needs to reach $10,000. Their fundraising progress is modeled by the function

Artist 52 [7]

Answer:

D) It is the amount they raise each week

Step-by-step explanation:

Given : Their fundraising progress is modeled by the function

f(x) = 435 + 1200x, where x is measured in weeks.

To Find :What is the meaning of the coefficient 1200?

Solution :

f(x) = 435 + 1200x

Where x denotes the week

if 1200 is raised fund so 1200x is the fund raised in x weeks

Thus the coefficient 1200 means the amount they raise each week.

Thus Option D is correct .

D) It is the amount they raise each week

Use the power property to rewrite log3x9.

Kitty [74]

Answer:

$\log _3\left(x^9\right)=9\log _3\left(x\right)$

Step-by-step explanation:

Given the expression

$\log _3\:x^9$

now rewriting the expression

$\log _3\:x^9$

$\mathrm{Apply\:log\:rule\:}\log _a\left(x^b\right)=b\cdot \log _a\left(x\right),\:\quad \mathrm{\:assuming\:}x\:\ge \:0$

$=9\log _3\left(x\right)$

Therefore,

$\log _3\left(x^9\right)=9\log _3\left(x\right)$

Carl can paint a room 3 hours faster than Jennifer can

Nata [24]

Jen take x hours.
Carl (x-3)hours.
Jen+carl take two hours;
This means;
In 1 hour, for they work
$\frac{1}{x} + \frac{1}{x-3}$
= $\frac{(x-3)+x}{x(x-3)}$
= $\frac{2x-3}{x(x-3)}$
Working together, they take two hours;
Take reciprocal of above equation and equate to two;
= $\frac{x(x-3)}{2x-3} =2$
$x^{2}$ -3x=4x-6
$x^{2} -7x+6=0$
$x^{2}$ -x-6x+6=0
x(x-1)-6(x-1)=0
(x-6)(x-1)=0
Take the bracket x-6=0 so that Carl works positive hours
x-6=0
x=6
