Answer:

d = 3

Step-by-step explanation:

According the figure:

10 + d + d + d = 19
d = 3

Answer Check Below:

⇒ 10 + 3 = 13

⇒ 13 + 3 = 16

⇒ 16 + 3 = 19

<h2>Therefore, d = 3.</h2>

Dafna11 [192]

R + t + L = 5(24).....r + t + L = 120
6r + 4t + 3L = 610
r = 2(t + L).......r = 2t + 2L

2t + 2L + t + L = 120
3t + 3L = 120

6(2t + 2L) + 4t + 3L = 610
12t + 12L + 4t + 3L = 610
16t + 15L = 610

16t + 15L = 610
3t + 3L = 120 ...multiply by -5
-------------------
16t + 15L = 610
-15t - 15L = - 600 (result of multiplying by -5)
-------------------add
t = 10

3t + 3L = 120
3(10) + 3L = 120
30 + 3L = 120
3L = 120 - 30
3L = 90
L = 90/3
L = 30

r = 2(t + L)
r = 2(10 + 30)
r = 2(40)
r = 80

so for all the bouquets, there are 80 roses, 30 lillies, and 10 tulips....but there are 5 bouquets...

so each bouquet has :
80/5 = 16 roses <==
10/5 = 2 tulips <==
30/5 = 6 lillies <==

Use the table below to answer this question:

tekilochka [14]

Using it's concept, it is found that the average rate of change of the function from x = -1 to x = 5 is of -1.

<h3>What is the average rate of change of a function?</h3>

It is given by the <u>change in the output divided by the change in the input</u>.

In this problem, the output changes by -6(from 7 to 1) when the input changes by 6(from -1 to 5), hence the average rate is given by:

r = -6/6 = -1.

Answer:

Step-by-step explanation:

This is a related rates problem from calculus using implicit differentiation. The main equation is Pythagorean's Theorem. Basically, what we are looking for is $\frac{dx}{dt}$ when y = 6 and $\frac{dy}{dt}=-2$ .

The equation for Pythagorean's Theorem is

$x^2+y^2=c^2$ where x and y are the legs and c is the hypotenuse. The length of the hypotenuse is 10, so when we find the derivative of this function with respect to time, and using implicit differentiation, we get:

$2x\frac{dx}{dt}+2y\frac{dy}{dt}=0$ and divide everything by 2 to simplify:

$x\frac{dx}{dt}+y\frac{dy}{dt}=0$ . Looking at that equation, it looks like we need a value for x, y, $\frac{dx}{dt}$ and $\frac{dy}{dt}$ .

Since we are looking for $\frac{dx}{dt}$ , that can be our only unknown and everything else has to have a value. So what do we know?

If we construct a right triangle with 10 as the hypotenuse and use 6 for y, we can solve for x (which is the only unknown we have, actually). Using Pythagorean's Theorem to solve for x:

$x^2+6^2=10^2$ and
