Answer:

90 cm^2

Step-by-step explanation:

The scale factor between triangle ABC and triangle PQR is 4:6 or  2:3

The scale factor is 2/3

When relating areas, we use the scale factor squared

Area of ABC = scale factor squared * Area of PQR

40 =  (2/3) ^2 Area of PQR

40  =4/9 Area of PQR

Multiply each side by 9/4

40 *9/4 = 9/4 *4/9 * Area of PQR

90 = Area of PQR

When we work with lengths of similar figures, we multiply by the scale factor.

When we work with areas of similar figures, we have a length and a width, so we are really multiplying by the scale factor two times, or the scale factor squared.

A = l*w

A = SF (l) * SF (w)

  = SF ^2 lw

So the area of the new  figure is the scale factor squared times the area of the old figure.

A new = SF^2 A old

To get from the old figure to the new figure we multiply by 6/4 or 3/2

A new =  (3/2)^2 (40)

A new = 9/4 * 40

           = 90

Answer:

C

Step-by-step explanation:

Since it is greater than or equal to, the graph line is a solid line.

Then, since we know that it is greater than, we know that we can shade above the graph line.

To check this, all you have to do is choose a random point in the shaded region and plug it in the equation. If it checks out, it is correct.

Answer:

Graph represented by option C is the correct choice.

Step-by-step explanation:

We are asked to graph an inequality [tex]y\geq2x-3[/tex].

The boundary line of our given inequality will be a solid line as we have greater than or equal to [tex]\geq[/tex] sign.

The boundary line of our given inequality would be [tex]y=2x-3[/tex].

Now, we will test point (0,0) to shade in the correct region as:

[tex]0\geq2(0)-3[/tex]

[tex]0\geq0-3[/tex]

[tex]0\geq-3[/tex]

Since the point (0,0) is a solution for our given inequality, therefore, the shaded area of our inequality will include point (0,0).

Answer:

Caleb arrived first 2 hours before Alyssa

Step-by-step explanation:

To solve the situation, find the speed per hour they were driving by dividing the distance they drove by the time it took.

Alyssa drove 105 miles in 3.5 hours or 105/3.5 = 30 miles per hour.

Caleb drove 168 miles in 4 hours or 168/4 = 42 miles per hour.

Since they both left at the same time and drove the same 210 miles to the beach, Caleb arrived first since he was driving faster.

He arrived in 210/42 = 5 hours.

Alyssa arrived in 210/30 = 7 hours.

He arrived 2 hours before her.

Answer:

The area of the triangle is [tex]128.62\ cm^{2}[/tex]

Step-by-step explanation:

we know that

Applying the law of sines

The area of a triangle is equal to

[tex]A=\frac{1}{2}(a)(c)sin(B)[/tex]

substitute the values

[tex]A=\frac{1}{2}(12)(22)sin(103\°)[/tex]

[tex]A=128.62\ cm^{2}[/tex]

Simplify brackets

2/5(x - 4) = 2x

Simplify 2/5(x - 4) to 2(x - 4)/5

2(x - 4)/5 = 2x

Multiply both sides by 5

2(x - 4) = 10x

Divide both sides by 2

x - 4 = 5x

Subtract x from both sides

-4 = 5x - x

Simplify 5x - x to 4x

-4 = 4x

Divide both sides by 4

-1 = x

Switch sides

The possible outcomes of tossing a coin 4 times with 2 or 3 heads can be represented using a tree diagram.

The possible outcomes of tossing a coin 4 times can be represented using a tree diagram. Each toss has 2 possible outcomes, either a head (H) or a tail (T). Starting with the first toss, there are 2 branches representing each possible outcome. For the second toss, each branch splits into 2 more branches representing the possible outcomes of the second toss, and so on. To find the outcomes with 2 or 3 heads, we need to count the paths on the tree diagram where there are 2 or 3 branches labeled as heads (H).

Let's label the paths as follows:

Y: HHTT
Z: HTHT
W: HTTH
X: TTHH

These are the possible outcomes with 2 or 3 heads. Therefore, the answer is option B. Z.

Answer:

The inverse function is a) h(x) = 1/2x - 1/2

Step-by-step explanation:

To find the inverse of any function, start by switching the x and f(x) values.

f(x) = 2x + 1

x = 2f(x) + 1

Now solve for the new f(x). The result will be your inverse function.

x = 2f(x) + 1

x - 1 = 2f(x)

(x - 1)/2 = f(x)

h(x) = 1/2x - 1/2

The inverse of the function f(x)=2x+1 is found by switching x and y in the function to create a new equation, rearranging that equation to solve for y, resulting in the inverse f^-1(x)=(x-1)/2.

To find the inverse of the function f(x)=2x+1, you first switch the roles of x and y in the function.

So, the inverse of the function is f^-1(x)=(x-1)/2.

Answer:

The reduced paid up insurance value is $47,770 and the annual premium is $4,097

The reduced paid-up insurance value is $6,692.83.

The annual premium for the reduced paid-up insurance is the amount of money that the policyholder would

We have,

To determine the reduced paid-up insurance value and the annual premium,

We need to use the information given and the following formulae:

The cash value of a policy is the amount of money that the policyholder would receive if they surrendered the policy before it matured.

The net amount at risk is the difference between the face value of the policy and the cash value.

The present value of a policy is the sum of the net amount at risk and the present value of the future premiums.

We are given that:

The policy is a 20-Year Endowment insurance policy, purchased when the policyholder was 40 years old.

The face value of the policy is $85,000.

The policyholder is now 50 years old.

The permanent insurance amount is $48.20 per thousand.

We need to determine the reduced paid-up insurance value and the annual premium.

We can use the following steps to determine the reduced paid-up insurance value and the annual premium:

Step 1: Calculate the cash value of the policy

The cash value of the policy can be calculated using the following formula:

Cash value = (Present value of future endowment benefits) - (Present value of future premiums)

We are given that the policy is a 20-Year Endowment policy, so the endowment benefit is $85,000. We can use the following formula to calculate the present value of the future endowment benefits:

Present value of endowment benefits = Endowment benefit / (1 + i)n

where i is the interest rate and n is the number of years.

Since the policyholder is 50 years old and the policy has 10 years left, we can assume an interest rate of 4% and calculate the present value of the endowment benefits as follows:

Present value of endowment benefits = $85,000 / (1 + 0.04)^10 = $48,598.20

We can calculate the present value of future premiums using the following formula:

Present value of future premiums = Net amount at risk / (Present value of an annuity due of $1 for n years, at i%)

where n is the number of years and i is the interest rate.

Since the policyholder has paid premiums for 10 years, there are 10 years left to pay. Using the same interest rate of 4%, we can calculate the present value of an annuity due of $1 for 10 years as follows:

Present value of an annuity due of $1 for 10 years, at 4% = 7.3601

We can now calculate the net amount at risk as follows:

Net amount at risk = Face value - Cash value

Face value = $85,000

Cash value = $48,598.20 + (Annual premium x Present value of an annuity due of $1 for 10 years, at 4%)

Net amount at risk = $85,000 - $48,598.20 - (Annual premium x 7.3601)

Step 2: Calculate the reduced paid-up insurance value

The reduced paid up insurance value is the amount of insurance that the policyholder can receive without paying any more premiums. It can be calculated as follows:

Reduced paid up insurance value = Cash value / Permanent insurance amount

Using the cash value calculated in Step 1 and the permanent insurance amount of $48.20 per thousand, we can calculate the reduced paid up insurance value as follows:

Reduced paid up insurance value.

= $48,598.20 / ($48.20 x 85)

= $6,692.83

Step 3: Calculate the annual premium

The annual premium for the reduced paid-up insurance is the amount of money that the policyholder would

Thus,

The reduced paid-up insurance value is $6,692.83.

The annual premium for the reduced paid-up insurance is the amount of money that the policyholder would
