Answer:

Max would save $126 if he quit smoking.

Step-by-step explanation:

It is given that the age of max is 33.

From the given table it is clear that the monthly premium for every $25000 of coverage for age group 31-40 non smoker male is 5.50 and smoker male is $9.00.

Total yearly premium for $75000 for non smoker male of 33 age is

[tex]P_1=5.50\times 3\times 12=198[/tex]

Total yearly premium for $75000 for smoker male of 33 age is

[tex]P_2=9.00\times 3\times 12=324[/tex]

If he quit smoking then he save

[tex]Saving=P_2-P_1[/tex]

[tex]Saving=324-198[/tex]

[tex]Saving=126[/tex]

Therefore max would save $126 if he quit smoking.

➷ 45 minutes is 3/4 of the total time

A simple way to do this is to find 1/4 of the time

To do this, divide by 3:

45/3 = 15

15 minutes is 1/4 of the time

To find the whole time, multiply this value by 4:

15 x 4 = 60

Subtract the time already passed from this:

60 - 45 = 15

It will take her 15 more minutes to finish building her wall.

Answer:

Part A) The cone couldn't contain all the ice cream if it melted.

Part B) The height of the cone would be [tex]8\ cm[/tex]

Part C) The height of the cylinder would be [tex]3\ cm[/tex]

Step-by-step explanation:

Part A) Determine whether the cone could contain all of the ice cream if it melted

step 1

Find the volume of the ice cream (sphere)

The volume is equal to

[tex]V=\frac{4}{3}\pi r^{3}[/tex]

we have

[tex]r=4/2=2\ cm[/tex] -----> the radius is half the diameter

substitute

[tex]V=\frac{4}{3}\pi (2)^{3}=\frac{32}{3}\pi\ cm^{3}[/tex]

step 2

Find the volume of the cone

The volume is equal to

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

we have

[tex]r=4/2=2\ cm[/tex] -----> the radius is half the diameter

[tex]h=7.5\ cm[/tex]

substitute

[tex]V=\frac{1}{3}\pi (2)^{2}(7.5)=\frac{30}{3}\pi\ cm^{3}[/tex]

step 3

Compare the volume of the sphere and the volume of the cone

[tex]\frac{30}{3}\pi\ cm^{3} < \frac{32}{3}\pi\ cm^{3}[/tex]

The volume of the cone is less than the volume of the sphere

therefore

The cone couldn't contain all the ice cream if it melted.

Part B) What would be the smallest cone in height in whole centimeters that would allow the cone to contain all of the melted ice cream if the diameter of the cone remains unchanged

The volume of the cone is equal to

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

we have

[tex]V=\frac{32}{3}\pi\ cm^{3}[/tex]

[tex]r=2\ cm[/tex]

substitute in the formula and solve for h

[tex]\frac{32}{3}\pi=\frac{1}{3}\pi (2)^{2}h[/tex]

simplify

[tex]32=(2)^{2}h[/tex]

[tex]32=4h[/tex]

[tex]h=32/4=8\ cm[/tex]

Part C) If the container of the ice cream changed to a cylinder as shown in the diagram below, what would be the smallest height of the cylinder needed to the nearest whole centimeter to contain the melted ice cream

The volume of the cylinder is equal to

[tex]V=\pi r^{2}h[/tex]

we have

[tex]V=\frac{32}{3}\pi\ cm^{3}[/tex]

[tex]r=2\ cm[/tex]

substitute in the formula and solve for h

[tex]\frac{32}{3}\pi=\pi (2)^{2}h[/tex]

simplify

[tex]\frac{32}{3}=(2)^{2}h[/tex]

[tex]\frac{32}{3}=4h[/tex]

[tex]h=\frac{32}{12}=2.67\ cm[/tex]

Round to the nearest whole centimeter

case 1) Circle open parentheses x plus 2 close parentheses squared plus open parentheses y minus 6 close parentheses squared equals 4 translated 2 units right and 6 units down

Step-by-step explanation:

Verify the 4 Options

case 1) Circle open parentheses x plus 2 close parentheses squared plus open parentheses y minus 6 close parentheses squared equals 4 translated 2 units right and 6 units down

The equation of the circle is

[tex](x+2)^{2}+(y-6)^{2}=4[/tex]

The center of the circle is the point [tex](-2,6)[/tex]

The rule of the translation is

[tex](x,y)-------> (x+2,y-6)[/tex]

Applying the rule to the center

[tex](-2,6)-------> (-2+2,6-6)[/tex]

[tex](-2,6)-------> (0,0)[/tex]

Therefore

The translation results in a circle whose center is at the origin

case 2) Circle open parentheses x minus 1 close parentheses squared plus open parentheses y plus 2 close parentheses squared equals 4 translated 1 unit left and 2 units down

The equation of the circle is

[tex](x-1)^{2}+(y+2)^{2}=4[/tex]

The center of the circle is the point [tex](1,-2)[/tex]

The rule of the translation is

[tex](x,y)-------> (x-1,y-2)[/tex]

Applying the rule to the center

[tex](1,-2)-------> (1-1,-2-2)[/tex]

[tex](1,-2)-------> (0,-4)[/tex]

Therefore

The translation results in a circle whose center is not at the origin

case 3) Circle open parentheses x minus 2 close parentheses squared plus open parentheses y plus 3 close parentheses squared equals 4 translated 2 units right and 3 units up

The equation of the circle is

[tex](x-2)^{2}+(y+3)^{2}=4[/tex]

The center of the circle is the point [tex](2,-3)[/tex]

The rule of the translation is

[tex](x,y)-------> (x+2,y+3)[/tex]

Applying the rule to the center

[tex](2,-3)-------> (2+2,-3+3)[/tex]

[tex](2,-3)-------> (4,0)[/tex]

Therefore

The translation results in a circle whose center is not at the origin

case 4) Circle open parentheses x minus 3 close parentheses squared plus open parentheses y minus 5 close parentheses squared equals 4 translated 3 units left and 5 units up

The equation of the circle is

[tex](x-3)^{2}+(y-5)^{2}=4[/tex]

The center of the circle is the point [tex](3,5)[/tex]

The rule of the translation is

[tex](x,y)-------> (x-3,y+5)[/tex]

Applying the rule to the center

[tex](3,5)-------> (3-3,5+5)[/tex]

[tex](3,5)-------> (0,10)[/tex]

Step-by-step explanation:

For this question we need to use the Pythagorean Theorem (a2+b2=c2) since the rectangle is being divided into two triangles.

we know the length of the triangle (63) and we know the hypotenuse (65) but not the width. To find the width, we can plug the values we know into our formula.

(63) squared + b squared = (65) squared

solve.

3969 + b squared = 4225

subtract 3969 from both sides.

b squared = 256

√b² = √256

b=16

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let L and W represent the length and width of the field. Then the perimeter is given by ...

  P = 2(L +W)

Filling in the given information, we have ...

  320 = 2(L +W)

  L = W +48 . . . . . . the length is 48 ft longer than the width

Using the second equation in the first, we get

  320 = 2((W +48) +W)

  320 = 4W +96 . . . . . . simplify

  224 = 4W . . . . . . . . . . subtract 96

  56 = W . . . . . . . . . . . . .divide by 4

  L = 56 +48 = 104 . . . . find L using the above relation

The width of the field is 56 ft; the length is 104 ft.

The width of the playing field is 56 ft and the length is 104 ft.

To solve this problem, let's set up an equation using the information given. Let's say the width of the field is x ft. Since the length is 48 ft longer than the width, the length can be represented as x + 48 ft. The formula for the perimeter of a rectangle is P = 2(l + w), so we can set up the equation: 320 = 2(x + 48 + x). Now, we can solve for x by simplifying and solving the equation.

320 = 2(2x + 48)

320 = 4x + 96

4x = 320 - 96

4x = 224

x = 224/4

x = 56

So, the width of the field is 56 ft and the length is 56 + 48 = 104 ft.

To solve this problem, we must use the formula for the perimeter of a rectangle, which is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.

According to the question, the length is 48 ft longer than the width, therefore we could express the length as L = W + 48. The perimeter provided is 320 ft. Now we can plug these values into the perimeter formula.

320 = 2(W + 48) + 2W

After simplification, this formula becomes 320 = 4W + 96.

To isolate W, you subtract 96 from both sides to get: 320 - 96 = 4W + 96 - 96, which simplifies to 224 = 4W. Dividing both sides by 4 gives W = 56 ft. This is the width of the field. The length, then, is 56 ft + 48 ft = 104 ft (since the length is 48 ft longer than the width).

So, the dimensions of the field are 104 feet by 56 feet

Answer:

If a fair coin is tossed three times, sample = 2^3 = 8 (hhh, hht, hth, thh, htt, tht, tth, ttt) where h=head and t=tail.

Probability of getting one:

Outcomes with one head (h) = 3

P(1 h) = 3/8 = 0.375

The probability of getting exactly one tail when a fair coin is tossed three times in succession is 37.5%.

The probability of getting exactly one tail when a fair coin is tossed three times in succession can be found using the binomial probability formula.

Let's denote success as getting a tail and failure as getting ahead. The probability of success, denoted as p, is 0.5 since the coin is fair and has an equal chance of landing on heads or tails. The probability of failure, denoted as q, is also 0.5.

Using the binomial probability formula: P(X = k) = [tex]C(n, k) * p^k * q^(n-k)[/tex], we can calculate the probability as follows:

Therefore, the probability of getting exactly one tail when a fair coin is tossed three times in succession is 0.375 or 37.5%.

Answer:

Exponential Function

Step-by-step explanation:

The y-axis represents the number of Bacteria and x-axis represents the number of hours. If you observe closely you will see that the number of bacteria are doubling after each hour. For example, at time = 4 hours the number of Bacteria were about 50, at time = 5 hours the number of Bacteria were about 100 and at time = 6 hours the number of Bacteria increased to about 200.

This type of behavior is a property of exponential functions where we see a multiplicative rate of change in the values i.e. each value is a multiple of previous value. A rough model for this function would be:

[tex]f(x)=f(0)(2)^{x}[/tex]

Where, f(0) represents the number of bacteria at time = 0 hours i.e. number of Bacteria initially present and "x" represents the number of hours.

Answer:

B

Step-by-step explanation:

We know:

1. Replacing -x into x of an equations reflects the graph on the y-axis

2. If f(x) is a function, then f(x)+a is a vertically translated graph of the original graph, a units up

Looking at the original function of ln x and the transformed graph of ln(-x) +5, we see that we have replaced x with -x, which means it is a reflection across the y-axis.

Also, we have added a five after the function, so that means it is a vertical translation of 5 units up.

Looking at the answer choices, we see that B is the correct answer.

Answer:

Step-by-step explanation:

Divide through by 2

2a² - 5a + 3 = 0

To factor the quadratic

Consider the factors of the product of the coefficient of the a² term and the constant term which sum to give the coefficient of the x- term

product = 2 × 3 = 6 and sum = - 5

The factors are - 2 and - 3

Use the factors to split the a- term

2a² - 2a - 3a + 3 = 0 ( factor the first/second and third/fourth terms )

2a(a - 1) - 3(a - 1) = 0 ← factor out (a - 1)

(a - 1)(2a - 3) = 0

Equate each factor to zero and solve for a

a - 1 = 0 ⇒ a = 1

2a - 3 = 0 ⇒ 2a = 3 ⇒ a = [tex]\frac{3}{2}[/tex]

Answer:

a = 3/2 or 1
