The amount that the person get after he home suffers $500,000 in damages is $20000.

Deductible amount is the amount which is paid by one in the starting of any policy.

The homeowner’s policy has a premium of $150. Thus, the amount paid in a year is,

[tex]150\times12=1800[/tex]

The home suffers $500,000 in damages and the deductible is of $5000. Thus, the amount remain is,

[tex]A=500000-5000\\A=495000[/tex]

The limit of the policy is $300000. Thus, the amount will be remained as,

[tex]A=495000-300000\\A=195000[/tex]

If we include the deductible amount, then,

[tex]A=195000+5000\\A=200000[/tex]

This amount does not include the premium paid by the homeowner. Hence the amount that the person get after he home suffers $500,000 in damages is $20000.

Answer:

A function R x that models the total revenue per game is as follows:

Rx = 87,5000 + 3,750x – 500x^2.

Step-by-step explanation:

Based on the information in the question, we have:

Rx = Total revenue per game

x = Number of $0.25 increases in the price of a hot dog

Average sales of hot dogs = 35,000

Effect of each 25 cent increase in the price on average sales = 35,000 - 2000x

Effect of each 25 cent increase in the price on selling price = 2.5 + 0.25x

Therefore, we have:

Rx = (35,000 - 2000x)(2.5 + 0.25x)

This can be solved further by opening the brackets as follows:

Rx = 87,5000 + 8,750x - 5,000x - 500x^2

Rx = 87,5000 + 3,750x – 500x^2

Therefore, a function R x that models the total revenue per game is Rx = 87,5000 + 3,750x – 500x^2.

Answer:

Option B.

Step-by-step explanation:

Inverse function:

Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.

The domain of the inverse function(x values) is the range of the original function(y values).

Original function:

[tex]f(x) = \sqrt{x} - 5[/tex]

Domain is [tex][0,\infty)[/tex], and when [tex]x = 0, f(x) = -5[/tex]. So the range is [tex][-5,\infty][/tex], that is, [tex]y \geq -5[/tex]

Inverse function:

[tex]y = \sqrt{x} - 5[/tex]

Exchanging x and y

[tex]x = \sqrt{y} - 5[/tex]

[tex]\sqrt{y} = x + 5[/tex]

[tex](\sqrt{y})^2 = (x+5)^2[/tex]

[tex]y = (x+5)^2[/tex]

The inverse function is [tex]f^{-1}(x) = (x+5)^2[/tex]

Domain:

Range of the original function is [tex]y \geq -5[/tex], so the domain of the inverse function is [tex]x \geq -5[/tex]. The correct answer is given by option B.

Answer:

B. f ^ -1 (x) = (x + 5) ^ 2;

Answer: 19 years

Step-by-step explanation:

Given

Amount invested [tex]\$400[/tex]

Rate of interest [tex]R=6\%[/tex]

after 1-year amount becomes

[tex]A=400\left (1+6\%\right)\\A=400\left (1+0.06\right)\\A=400\times 1.06\\A=\$424[/tex]

After n years it is

[tex]A=400\left (1.06\right)^n[/tex]

Sum accumulated is [tex]\$1200[/tex]

[tex]\Rightarrow 1200=400\left(1.06\right)^n\\\Rightarrow 3=\left(1.06\right)^n\\\text{Taking log both sides}\\\Rightarrow n=\dfrac{\ln 3}{\ln 1.06}\\\\\Rightarrow n=18.85\approx 19\ \text{years}[/tex]

The expression that defines Sn is option (A), Sn = lim n->∞ (1/4)^n is the correct answer.

A sequence is defined as an arrangement of numbers in a particular order.  A series is the cumulative sum of a given sequence of terms. Typically, these terms are real or complex numbers.

For the given situation,

The series is 1/4 + 1/16 + 1/64 + 1/256.

⇒ [tex]\frac{1}{4}+\frac{1}{16} +\frac{1}{64} +\frac{1}{256}[/tex]

⇒ [tex]\frac{1}{4}+\frac{1}{4^{2} } +\frac{1}{4^{3} } +\frac{1}{4^{4} }[/tex]

Thus the sum of this series can be obtained by the expression,

[tex]S_{n}= \lim_{n \to \infty} (\frac{1}{4^{n}})[/tex]

⇒ [tex]S_{n}= \lim_{n \to \infty} (\frac{1}{4})^{n}[/tex]

Hence we can conclude that the expression that defines Sn is option (A), Sn = lim n->∞ (1/4)^n is the correct answer.

Step-by-step explanation:

The requried simplified value of x in the intersection of two lines is 6.

Opposite angles are a pair of angles that are formed when two lines intersect. The two angles are located on opposite sides of the point where the two lines intersect.

Opposite angles are also called vertical angles, and they have equal measures. This means that if we know the measure of one opposite angle, we can find the measure of the other opposite angle by setting them equal to each other.

Here,
When two lines intersect, opposite angles are equal. So, we can set the two opposite angles equal to each other and solve for x.

Given that the opposite angles are 3x + 2 and 20 degrees, we have:

3x + 2 = 20

Subtracting 2 from both sides, we get:

3x = 18

Dividing both sides by 3, we get:

x = 6

Therefore, the value of x is 6.

Answer:

He's correct its 432

Step-by-step explanation:

Lower standard deviation for chip length ensures chips are more consistent and roughly the same size, meeting quality standards.

As the quality control manager of a snack food manufacturer, I desire a higher standard deviation when measuring for the length of chips. A higher standard deviation indicates a greater variability in chip lengths.

While it may seem counterintuitive, having a higher standard deviation allows for a range of chip sizes, accommodating different consumer preferences. Some customers may prefer shorter chips, while others may prefer longer ones.

By allowing for some variation in size, the snack food manufacturer can cater to a broader customer base and increase market appeal.

Additionally, a higher standard deviation can be beneficial for marketing purposes, as it creates an impression of natural, handcrafted chips rather than mechanically uniform ones.

Answer:

Step-by-step explanation:

According to Alternate Interior Angles Theorem (in a graph that shows a transversal crossing two parallel lines, the alternate interior angles are congruent), The angle that includes the sum of 39° and x° is congruent to 132°.

So: 39° + x° = 132°, and x = 93

Answer:

(5,3)

Step-by-step explanation:

add the equations to eliminate to x's and get 8y=24

divide both sides by 8 to get y=3

then substitute in -2x+3(3)=-1 to solve for x

so x=5 so the solution is (5,3)

Answer:

[tex]x=5 \\y=3[/tex]

Step-by-step explanation:

[tex]-2x+3y=-1\\2x+5y=25[/tex]

Add these equations to eliminate x:

[tex]8y=24[/tex]

Then, solve [tex]8y=24[/tex] for y:

[tex]8y=24[/tex]

[tex]\frac{8y}{8} =\frac{24}{8}[/tex] (divide both sides by 8)

[tex]y=3[/tex]

Now let's find the value of x:

Substitute 3 for y in [tex]-2x+3y=-1[/tex]

[tex]-2x+(3)(3)=-1[/tex]

[tex]-2x+9=-1[/tex] (simplify both sides of the equation)

[tex]-2x+9+-9=-1+-9[/tex] (add both sides by -9)

[tex]-2x=-10[/tex]

[tex]\frac{-2x}{-2} =\frac{-10}{-2}[/tex]  (divide both sides by -2)

[tex]x=5[/tex]

Therefore, the value of x = 5 and y = 3

  6) 90°

Step-by-step explanation:

The relevant relations are ...

__

2) Arc WXY = 2×angle WDY = 2(99°) = 198°

__

4) Arc CLE is 2×angle CDE = 2(97°) = 194°

  Arc DE = 360° -72° -194° = 94°

  angle C = (arc DE +arc EL)/2 = (94° +104°)/2 = 99°

__

6) angle C = (360° -arc EC -arc CD)/2 = (360° -71° -109°)/2 = 90°

Answer:

2.

Given:

m arc WXY=2×99°=198°[central angle is equal to the twice of its inscribed angle]

4.Arc CLE =2x< CDE = 2×97° = 194°[central angle is equal to the twice of its inscribed angle]

again

Arc DE =360° -72° -194° = 94°[from complete turn]

and

angle C =½ (arc DE +arc EL) =½ (94° +104°) = 99°

6) angle C =½ (360° -arc EC -arc CD)

=½ (360° -71° -109°)= 90°
