Answer:
1.5A
Step-by-step explanation:
To find the current that the motor will require, we can use the formula for power, which is given by:
P = E * I
where P is the power, E is the voltage, and I is the current. Substituting the values for the power and voltage into the formula, we get:
180 = 120 * I
Dividing both sides of the equation by 120, we get:
1.5 = I
Therefore, the current that the motor will require is 1.5 amps.
Step-by-step explanation:
The formula for power is P = E x I, so the current required by the motor is equal to the power divided by the voltage. In this case, the current required by the motor is 180 watts / 120 volts = 1.5 amps.

Answer:
A(W)=500-19W
177W = 500 - 19W
177W + 19W = 500

Each nack cot $0. 75 , and the amount wa charged to Dave’ account. What amount hould be on Dave’ account for nack lat month?
If Dave bought 5 packs of snacks, then the amount on Dave's account for snack last month should be $3.75.
Dave purchased 5 packs of snacks last month and the cost of each pack was $0.75. The total cost of the snacks was charged to Dave's account, so his account balance should reflect the total cost of the snacks. In this case, Dave purchased 5 packs of snacks, so the total cost would be $3.75 ($0.75 x 5). Therefore, Dave's account balance should show $3.75 for the snack purchases last month. This amount is the sum of the individual cost of each snack pack, multiplied by the number of packs Dave purchased. In this case, the amount on Dave's account for snack last month should be $3.75.
5 packs of snacks x $0.75 = $3.75

The volume of the crater is 64800000 m³
Calculating volume of the craterFrom the question, we are to determine the volume of the crater.
From the given information,
d = 2∛(V/0.3)
To determine the volume,
First, we will solve for V in the equation
d = 2∛(V/0.3)
Divide both sides by 2
d/2 = ∛(V/0.3)
Take the cube of both sides
(d/2)³ = V/0.3
Then,
V = 0.3(d/2)³
Now, substitute the value of the diameter
d = 1200m
Then,
V = 0.3(1200/2)³
V = 0.3(600)³
V = 64800000 m³
Hence, the volume is 64800000 m³

Step-by-step explanation:
the probability of an archer hitting her target is 83%. suppose she has 20 shots to take, and each shot is independent of the others. let x represent the number of targets hit. what is the mean of x?
the probability of an archer hitting her target is 83%.The mean of x is 16.6 (16.6 targets hit).
The probability of the archer hitting her target is 83%. This means that for each shot she takes, the probability of her hitting her target is 0.83. Since she has 20 shots to take, the expected number of targets hit is 20 x 0.83, which is 16.6.
The mean of x, which is the number of targets hit, is therefore 16.6. This can be calculated by taking the probability of success (0.83) multiplied by the number of trials (20), which gives the expected value of 16.6.

The probability is 0.07777.
What does probability mean?
The number of desired outcomes divided by the total number of outcomes yields a probability.
We are attempting to determine the likelihood, out of 10, that the first chip will be white and the second won't be green while assuming that one chip is white and two are green.
1/10 of the time, the initial chip will be white. If the first chip is white, there is a 7/9 chance that the second chip will be a color other than green. The desired probability is therefore provided by:
Ten chips are present.
white 1
red 4
green 2
Blue 3
the likelihood of selecting the W chip is one in ten, or 0.10
There are now only 9 chips left (the first chip was not replaced)
Selecting a non-green chip has a probability of (9-2)/9 = 7/9 = 0.7777.
you multiply the two probabilities to obtain the overall probability at this point.
probability is 0.1 to 0.7776.
The probability is equal to 0.07777, which implies that it must be less than 0.1.

Step-by-step explanation:
[tex]x^{3} +5x^{2} -3x+7[/tex]
it changed the sign in the second to the third term，so,it was one root
[tex]-x^{3} +5x^{2} +3x+7[/tex]
Change the coefficients of odd items, and the signs of the first to second items change, so there is also a root.
Answer:
Maximum of 2 positive real rootsExactly 1 negative real rootStep-by-step explanation:
Descartes' Rule of Signs tells us the maximum number of positive and negative real roots in a polynomial function.
Positive root case
[tex]\begin{aligned}p(x)&=(x)^3+5(x)^2-3(x)+7\\ &=+x^3+5x^2-3x+7\end{aligned}[/tex]
Check the signs of the coefficients. As there are 2 sign changes, the maximum possible number of positive roots is 2.
However, as some pairs of roots may be complex, count down by two's to find the complete list of the possible number of roots.
So there may be as many as 2 real roots or there might also be no real roots (zero).
Negative root case
[tex]\begin{aligned}p(-x)&=(-x)^3+5(-x)^2-3(-x)+7\\&=-x^3+5x^2+3x+7\end{aligned}[/tex]
Check the signs of the coefficients. As there is one sign change, the maximum possible number of negative roots is 1. We can't count down by two's since this would give us a negative number. Therefore, there is exactly 1 negative root.
Note: There is one real negative root of the given function at x ≈ -5.74 and two complex roots at x = 0.37 + 1.04i and x = 0.37 - 1.04i.
if the nth term of a number sequence is n^2+1 find the first three terms and the tenth term
Answer: The first three terms of the sequence are: 1^2+1=2, 2^2+1=5, 3^2+1=10
The tenth term of the sequence is: 10^2+1=101.
Step-by-step explanation: To find the first three terms of a number sequence in which the nth term is n^2+1:
For the first term, set n equal to 1 and substitute it into the formula: 1^2 + 1 = 2
For the second term, set n equal to 2 and substitute it into the formula: 2^2 + 1 = 5
For the third term, set n equal to 3 and substitute it into the formula: 3^2 + 1 = 10
To find the tenth term of the same sequence, set n equal to 10 and substitute it into the formula: 10^2 + 1 = 101.

A cubic polynomial function f is defined by. 3. 2. ( ) 4. f x x ax bx k where a, b, and k are constants
In a cubic polynomial function f is defined by f(x) = 4x³ + ax² + bx + k, where a, b, k, are constants and has a local minimum at x = -2 and a local maximum at x = 0, then values of a and b is 12 and 0 respectively. If integrate of f(x)dx = 32 from 0 to 1, then value of k is 27.
The given cubic polynomial function is
f(x) = 4x³ + ax² + bx + k
f'(x) = 12x² + 2ax + b
f''(x) = 24x + 2a
At local maximum f' = 0
f'(0) = 12×(0)² + 2a×(0) + b = 0
b = 0
At local minimum, f' = 0
That is f'(-2) = 0 and f''(-2) > 0
f'(-2) = 12×(-2)² + 2a×(-2) + b = 0
48 - 4a + b = 0
4a - b = 48
a = 12
Therefore, f(x) = 4x³ + 12x² + k
Integrate f(x)dx = 32 from 0 to 1, that is
∫₀¹ f(x)dx = 32
∫₀¹ (4x³ + 12x² + k) dx = 32

A shipping container will be used to
transport several 150-kilogram crates
across the country by rail. The greatest
weight that can be loaded into the
container is 27500 kilograms. Other
shipments weighing 6800 kilograms have
already been loaded into the container.
Write and solve an inequality which can
be used to determine x, the number of
150-kilogram crates that can be loaded
into the shipping container.
Answer:
x=138
Step-by-step explanation:
The question is a high school Mathematics problem. It involves using inequalities to solve a practical problem about a shipping container's weight limit. The answer found was that a maximum of 138 crates can be added to the container.
Explanation:In this Mathematics problem, we have a shipping container that can hold a maximum weight of 27500 kilograms and there are already shipments totaling 6800 kilograms inside. We want to find out how many 150-kilogram crates (let's call this number 'x') can be added to the container without exceeding the maximum allowable weight.
Firstly, we build an inequality. The total weight of the container should not exceed 27500 kilograms, so we have:
6800 (the weight of the already loaded shipments) + 150*x (the weight of the x crates) ≤ 27500
This simplifies to:
150*x ≤ 20700 (because 27500-6800=20700)
Finally, to solve the inequality for 'x', divide throughout by 150:
x ≤ 138 (because 20700/150=138)
So, 138 is the maximum number of 150-kilogram crates that can be loaded into the shipping container without violating the weight constraint.

The month they would have the same amount of money is 2 months.
When would they have the same amount of money?The linear equation that can be used to represent the total amount of money saved by each person is
Total amount saved = amount started with + (amount deposited per month x number of months)
Amount saved by Tonya = $60 + $20m
Amount saved by Jull = $20 + $40m
When they save the same amount of money, the two two above equations would be equal:
60 + 20m = 20 + 40m
In order to determine the value of m, take the following steps:
60 - 20 = 40m - 20m
40 = 20m
m = 40 / 20
m = 2
