The burner is the engine of the balloon. What is the role of a resistor in an engine?
A ballast resistor is utilized inside the ignition system of automobile engines or balloons. it acts as a resistor for the ignition ballast.
Between the main source of both the ignition coil & the coil stud, there's an ignition ballast resistor. It lowers the ignition coil's risk of failure.
An ignition ballast resistance assists in lowering the coil voltage & coil current when the generator revs the engine.
Minimal current consequently results in a low-temperature increase. Additionally, the ignition coil lives a long time as a result.
However, an ignition system requires a greater voltage that is also the same as the power source's voltage. Therefore, a resistor for the ignition ballast is connected to the jumper wire. The jumper wire additionally supplies the ignition with the necessary voltage when starting the engine.

Each night Liz spends at least 45 minutes and no more than 120 minutes on her phone.
Choose which double inequality describes how long Liz spends on her phone each night.
"n" will be used as your variable.
pls help me its due today
Using the given information, we can write the compound inequality for the variable n:
45 ≤ n ≤ 120
How to write the inequalities?
Here we know that Liz spends at least 45 minutes and no more than 120 minutes on her phone.
So if we define the variable n as:
n = number of minutes that Liz spends on her phone.
We know that n must be larger than or equal to 45, so we can write the first inequality:
45 ≤ n
And we also know that it must be smaller than or equal to 120, then the other inequality is:
n ≤ 120
Combining the two we can write the compound inequality:
45 ≤ n ≤ 120

The crate's density in pounds per cubic foot?
What is the crate's density in pounds per cubic foot?Since the crate of medicine with a density of 2050 kilograms per cubic meter will be shipped from England to the U.S, we require its density in pounds per cubic foot.
To do this, we convert the density in kilograms per cubic foot to pounds per cubic foot by using the ratios of conversion given
Since the density of the crate in kilograms per cubic meter is
2050 kg/m³, using the conversion ratios, we have
2050 kg/m³ = 2050 kg/m³ × 1 m³/35.3 ft³ × 2.2 lb/kg
= 4510 lb/m³ × 1 m³/35.3 ft³

The amount in the account is ____.
(Do not round until the final answer. Then round to the nearest cent as needed.)
The amount in the account is $3499. 2
How to determine the compound interestThe formula for determining compound interest is given as;
A = P ( 1 + r/ n) ^nt
Given that;
A is the final amountP is the principal amountr is the ratet is the time taken n is the number of times interest applied per periodSubstitute the values into the formula, we have;
A = $3000 ( 1 + 0. 04 / 0. 5) ^(0.5× 4)
Find the exponential value
A = $3000 ( 1 + 0. 04 / 0. 5) ^2
A = $3000( 1+ 0. 08)^2
Expand the bracket, we get;
A = $3000 (1. 08)^2

The partial fraction of the compound fraction [tex]\frac{x + 7}{(x - 3)(x - 5)}[/tex] is [tex]\frac{6}{x - 5}[/tex] [tex]-\frac{5}{x - 3}[/tex]
What is a partial fraction?Partial Fractions are the fractions that are formed when a complex rational expression is split into two or more simpler fractions.
When fractions become too cumbersome to solve we split them into simpler units called partial fractions so that mathematical operations can easily be carried out on them.
[tex]\frac{x + 7}{(x - 3)(x - 5)}[/tex] can be split into the form, [tex]\frac{A}{x - 3} + \frac{B}{x - 5}[/tex]
where A and B are constants.
so,
[tex]\frac{x + 7}{(x - 3)(x - 5)}[/tex] = [tex]\frac{A}{x - 3} + \frac{B}{x - 5}[/tex]
taking the LCM of the denominators of the split fractions, we have
(x-3)(x-5)
multiply A by x -5 and B by x - 3
fraction becomes
[tex]\frac{x + 7}{(x - 3)(x - 5)}[/tex] = [tex]\frac{A(x - 5) + B(x - 3)}{(x - 3)(x - 5)}[/tex]
since the denominators of the Left hand side and right hand side are same, we equate the numerators
A(x - 5) + B( x - 3) = x + 7
Using the cover up rule method,
to find A, we substitute x = 3 into the equation so that B becomes zero
A(3 - 5) = 3 + 7
-2A = 10
A = 10/-2
A = -5
To find A put x = 5 so that A = 0
B(5 - 3) = 5 = 7
2B = 12
B = 12/2 = 6
Substituting B and A into the partial fractions above
we have,
[tex]\frac{6}{x - 5}[/tex] [tex]-\frac{5}{x - 3}[/tex]

Answer: y= (2/3)x - 2
Step-by-step explanation:
The biggest way to remember equations like these is to know rise over run which means however many times it goes up until it intersects with both x and Y will be on the top of the fraction and however many times it goes to the right until it intersects with both x and y will be on the bottom of the fraction. So since it hits (0, -2) then intersects at (3,0) it will be 2/3x and the Y is where X equals zero so it would be -2. Hope that helps!
Answer:
y = [tex]\frac{2}{3}x - 2[/tex]
Step-by-step explanation:
Step 1:
Choose two points on the graph, (x1, y1) and (x2, y2), to find the slope.
Find the ratio between change in y-values and change in x-values.
m = (y2 - y1) / (x2 - x1)
Points I picked:
(x1, y1) = (0, -2)
(x2, y2) = (3, 0)
Then,
m = (0 - (-2)) / (3 - 0)
m = 2/3
Step 2 :
Find the y-intercept from the graph. That is the point at which the line intersects the y-axis.
The y-intercept is -2.
b = -2
Step 3 :
Use the slope (m) and y-intercept (b) to write the equation in slope-intercept form:
y = mx + b
Substitute m = 2/3 and b = -2
y = 2/3 x - 2

Explain about the Congruence postulate?
A postulate is an assertion that is not backed by any evidence. Axiom is another name for a postulate. For instance, you would believe Pam if she said that all of her siblings were at least five feet one tall since you are aware of her height and that of all of her siblings, who are all taller than her.
When two figures or objects in geometry have the same shapes, sizes, or are mirror images of one another, they are said to be congruent.
Shapes that are identical to one another are said to be congruent. Both the matching sides and the corresponding angles match. We must examine all of the shapes' angles and sides in order to accomplish this. Two shapes that are similar to one another can be stacked perfectly.

Write your answer in roster form or as 0.

The value of the sets are A ∩ ∅ = ∅ and A' ∪ U = {f, g, h, p, q, r}.
How to determine the sets?Given: U = {f, g, h, p, q, r} and A = {g, p, r}
We are to find: (a)A ∩ ∅ and (b) A' ∪ U
(a) A ∩ ∅
The symbol ∩ means intersection. This tells us what sets have in common. Also, the symbol ∅ means an empty set or null. That is a set that does not have any element
The intersection of a set with the empty set is the null set. Thus:
A ∩ ∅ = ∅
(b) A' ∪ U
The set U is called the universal set
A' means elements not in set A but in set U
The symbol ∪ means union, A' ∪ U will give a list of elements in A' and U combined without repetition. Thus:
A' ∪ U = {f, h, q} ∪ {f, g, h, p, q, r} = {f, g, h, p, q, r}
Therefore, A ∩ ∅ = ∅ and A' ∪ U = {f, g, h, p, q, r}. They should be entered into the boxes accordingly
