Answer:

e = -2

Step-by-step explanation:

 

-13+7e=-3e-33

We move all terms to the left:

-13+7e-(-3e-33)=0

We get rid of parentheses

7e+3e+33-13=0

We add all the numbers together, and all the variables

10e+20=0

We move all terms containing e to the left, all other terms to the right

10e=-20

e=-20/10

A garden hose emits 9 quarts of water in 6 seconds how much did the water emit in 10seconds
kolbaska11 [484]

Answer: The  15 quarts water emit in 10 second


Step-by-step explanation:

Given: A garden hose emits 9 quarts of water in 6 second.

To find : how much did the water emit in 10 second.

Explanation:

We are given that

                    In 6 second a garden hose emits water= 9 quarts.

                   In 1 second a garden hose emits water = \frac{9}{6} quarts.

                  In 10 second a garden hose emits water=10×\frac{9}{6} quarts

                     Total water emits in 10 second = 15 quarts.

Therefore, the  15 quarts water emits in 10 second.

Find an equation equivalent to r = 10 sinθ in rectangular coordinates
Flura [38]

Answer:

x^{2} + y^{2} - 10\cdot y = 0

Step-by-step explanation:

The following expressions are used to transform from polar into rectangular form:

r = \sqrt{x^{2}+y^{2}}

\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}

Now, the variables are substituted and equation is finally simplified:

\sqrt{x^{2}+y^{2}} = 10\cdot \frac{y}{\sqrt{x^{2}+y^{2}} }

x^{2}+y^{2} = 10\cdot y

The equivalent equation in rectangular coordinates is:

x^{2} + y^{2} - 10\cdot y = 0

Given g of x equals cube root of the quantity x minus 3, on what interval is the function positive? (–[infinity], –3) (–[infinit
Gelneren [198K]

the interval in which g(x) is positive is [3, ∞].

<h3>On what interval is the function positive? </h3>

Here we have the function:

g(x) = ∛(x - 3)

The interval in which the function is positive is defined by:

g(x) > 0.

Then we have:

∛(x - 3) > 0.

We need to solve that inequality for x.

∛(x - 3) > 0

The cube root respects the sign of the argument, then:

x - 3 > 0

x > 3

Then the interval in which g(x) is positive is [3, ∞].

A certain type of car has room for 4 passengers.
USPshnik [31]

The equation relating the number of cars to the number of passengers is p = 4n

<em><u>Solution:</u></em>

Given that certain type of car has room for 4 passengers

To find: write an equation relating the number of cars to the number of passengers

Let "n" be the number of cars

Let "p" be the number of passengers

From given information,

Car has room for 4 passengers. Therefore, we can frame,

number of passengers = 4 ( number of cars )

p = 4 (n)

p = 4n

Thus the equation relating the number of cars to the number of passengers is p = 4n
