Answer:

QR = 5

Step-by-step explanation:

Since the parallelograms are similar, then the ratios of corresponding sides are equal, that is

$\frac{AB}{PQ}$ = $\frac{BC}{QR}$ , then

$\frac{9}{3}$ = $\frac{15}{QR}$ ( cross- multiply )

9QR = 45 ( divide both sides by 9 )

QR = 5

Finding an Equation of a Tangent Line In Exercise, use implicit differentiation to find an equation of the tangent line to the g

Karo-lina-s [1.5K]

Answer:

$y=\frac{4}{3}-\frac{x}{3e}$

Step-by-step explanation:

Equation of tangent line of given function at (e,1) is found by implicitly differentiating the given function w.r.to x

$y^{2}+ln(xy)=2\\\\y^{2}+ln(x)+ln(y)=2\\\\\frac{d}{dx}(y^{2}+ln(x)+ln(y))=\frac{d}{dx}(2)\\\\2y\frac{dy}{dx}+\frac{1}{x}+\frac{1}{y}\frac{dy}{dx}=0\\\\\frac{dy}{dx}(2y+\frac{1}{y})=-\frac{1}{x}\\\\\frac{dy}{dx}=-\frac{y}{x(2y^{2}+1)}\\\\at (e,1)\\\\\frac{dy}{dx}=-\frac{1}{e(2+1)}\\\\\frac{dy}{dx}=\frac{1}{3e}$

Equation of tangent line is

y-y₁=m(x-x₁)

at (e,1)

$y-1=-\frac{1}{3e}(x-e)\\\\y=1-\frac{1}{3e}(x-e)\\\\y=1+\frac{1}{3}-\frac{x}{3e}\\\\y=\frac{4}{3}-\frac{x}{3e}\\$

A carpenter have several boards of equal length. He cuts 3/5 of each boards .After cutting the boards the carpenter notices that

LenaWriter [7]

So the board is divided into 5 pieces, and 2/5 of the board is left. The leftovers equal 4 originals. This is equal to 4 times 5.
equation:
2/5(5x)=20
2x=20
x=10
He started with 10 boards.
Hope this helps!

In a fixed-order-quantity system, when demand is uncertain, using economic order quantity (EOQ) based only on the average demand

Ganezh [65]

Answer:

b. False

Step-by-step explanation:

In a fixed-order-quantity system, when there is uncertainty in demand, the average demand will lead to a high probability of a stockout which is in contrast to what is stated in the question. Thus, the answer is false.

every evening jenna empties her pockets and puts her change in a jar. At the end of the week she counts her money. One week she

Darya [45]

Let Q= the number of quarters and D= the number of dimes.
Q+D= 40 coins
0.25Q+0.1D= $7.75
Rewrite equation 1 as: D = 40-Q and substitute into equation 2
0.25Q+0.1(40-Q)= 7.75 Simplify the left side
0.25Q+4-0.1Q= 7.75 Subtract 4 from both sides
0.25Q-0.1Q= 3.75 Convime like terms on left side
0.15Q= 7.75 Divide both sides by 0.15
Q=25 and D= 40-Q
D= 40-25 which is 15
So Jenna had 25 quarters and 15 dimes.
<span>To check multiply 25 x 25 and 15x10 which equals 625 and 150 this equals 775 so this is 7.75</span>
