Answer:

Max E=3.8 Voltage

Step-by-step explanation:

$maximum-value -of cos(\theta) =1, when \theta=0,360,720\\110\pi t=0, therefore t=0, 1.04, 2.08 etc$

A leaking pond looses 18 gallons of water in 34 hours , how many gallons will be left after 41 hours

Ann [662]

The amount of water left = 21.3 gallons.

We have a leaking pond which looses 18 gallons of water in 34 hour.

We have to determine how many gallons of water will be left after 41 hours.

<h3>What do you understand by gallon?</h3>

The gallon is a unit of volume in imperial units and United States customary units.

I gallon = 231 cubic inches = 3.785411784 liters.

According to question, we have -

Amount of water lost by the pond in 34 hours = 18 gallons

Therefore -

Amount of water lost by the pond in 1 hour = $\frac{18}{34}$

So, the amount of water loosed by the pond in 41 hours = $\frac{18}{34}\times 41$ = 21.3

Hence, the amount of water left = 21.3 gallons.

function g is a transformation of the parent exponential function f(x)=x^2. the graph of g is a translation right 5 and up 1 uni

adell [148]

The equation of g in the form y = ax² + bx +c is g(x) = x² - 10x + 26

What is a function ?

A function is a kind of rule that, for one input, it gives you one output. Image source: by Alex Federspiel. An example of this would be y=x2. If you put in anything for x, you get one output for y. We would say that y is a function of x since x is the input value.

Horizontal translation:

For a general function f(x) an horizontal translation of N units is written as:

g(x) = f(x + N)

If N is positive, the shift is to the left

If N is negative, the shift is to the right.

Vertical translation:

For a general function f(x) a vertical translation of N units is written as:

g(x) = f(x) + N

If N is positive, the shift is upwards

If N is negative, the shift is downwards.

First, we apply a translation to the right of 5 units, then at the moment we have:

g(x) = f(x - 5)

Then we translate the graph up 1 units, then:

g(x) = f(x - 5) + 1

Now we can replace it by the actual function to get:

g(x) = (x - 5)^2 + 1

= x² - 2*5*x + 25 + 1

= x² - 10x + 26

Sheila is moving to a new house. She rents a truck with a storage body as shown below.

patriot [66]

Answer:

volume of the storage body is 576. multiply by 9. she can fit 64 boxes

Step-by-step explanation:

so draw a line at the short end of the body so it would be 6ft x 4 ft x 2ft = 48 ft. then the rest of the body becomes 11 ft (15 ft minus 4 ft) x 8ft x 6ft =528. so 48 + 528 = 576 then you divide 576 by 9 and get 64.
