The required solution is 2t^2 -7t - 4.

It is required to find the product  of the problem.

The distributive property of multiplication lets you simplify expressions wherein you multiply a number by a sum or difference. According to this property, the product of a sum or difference of a number is equal to the sum or difference of the products.

Given that:

By the distributive property to find the product of (2t + 1) ( t - 4).

=(2t +1)(t -4)

= 2t^2 + 1t -8t - 4

= 2t^2 -7t - 4

Therefore, the required solution is 2t^2 -7t - 4.

Final answer:

The product of (2t + 1)(t - 4) is calculated using the FOIL method to be 2t² - 7t - 4.

Explanation:

To find the product of (2t + 1) and (t - 4), we use the distributive property (also known as the FOIL method in this context) to multiply each term in the first binomial by each term in the second binomial. Here is the step-by-step process:

Multiply the first terms: 2t × t = 2t².

Multiply the outside terms: 2t × -4 = -8t.

Multiply the inside terms: 1 × t = t.

Multiply the last terms: 1 × -4 = -4.

Add all the products together to get the final answer: 2t² + -8t + t + -4.

Combine like terms: 2t² - 7t - 4.

Thus, the product of (2t + 1)(t - 4) is 2t² - 7t - 4.

Answer: The answer is C

The reason for statement 2 of the two-column proof is : Definition of bisect ( optionC).

Since angle RPS is bisected, the two angles in which are formed will be equal. Bisecting an angles means dividing the angle into two equal part.

line PQ bisects RPS into two;

angle QPS = 61°

this means that RPQ is also 61°. Thus it is an acute angle. This is because 61° is an acute angle.

An acute angle is an angle that is less than 90°

Therefore, The reason for statement 2 of the two-column proof is : Definition of bisect

Final answer:

To express 42 + 24 differently, one might use the commutative property (24 + 42), break the numbers into tens and ones (40 + 20 + 2 + 4), or use rounding to aid mental addition (60 + 6). Each method simplifies the problem while reaching the same correct answer.

Explanation:

Another way to express 42 + 24 could be by rearranging the numbers to use commutative property of addition or by changing one or both of the numbers into a sum that makes mental addition easier. For example:

24 + 42 - Which uses the commutative property of addition, meaning that numbers can be added in any order and the result will be the same.

40 + 20 + 2 + 4 - Here we break down both numbers into tens and ones and add them separately.

60 + 6 - By rounding 42 up to the nearest ten (40) and adding 20, you get 60 plus the remaining 2 and 4 to add up to 6.

Each method provides a different way of reorganizing the original problem to potentially simplify the adding process or to suit mental math strategies. Remember, arithmetic has specific rules, but there's flexibility in how we apply them to reach the same correct answer. This shows the beauty and versatility of mathematics.

Final answer:

To express 42 + 24 differently, one can use the commutative property (24 + 42), factor out common numbers (2(21 + 12), or round and adjust (60 + 6), showcasing the variety of methods mathematics provides to reach the same answer.

Explanation:

The question asks for an alternative way to express the sum 42 + 24. One strategy is to use properties of numbers and operations to simplify and find patterns that make it easier to perform calculations in our head. For instance, using commutative property of addition, we can restate 42 + 24 as 24 + 42. Moreover, we can utilize the distributive property by factoring out a common number to make the addition easier, such as expressing it as 2(21 + 12) since both 42 and 24 are divisible by 2, or 6(7 + 4) if you notice that both numbers are divisible by 6. It's also possible to round numbers up, perform the addition, and then adjust back, for example: (40 + 20) + (2 + 4) which simplifies to 60 + 6. Each of these methods provides a different path to the same correct answer, exemplifying that mathematics offers numerous ways to solve a problem, which ultimately reinforces our understanding.

The expected value of buying a $1 ticket out of a lottery of 1000 tickets where the prize for the one winning ticket is $1000 is approximately -$0.999. This means that, on average, you can expect to lose about $0.999 for each ticket you buy.

To calculate the expected value, we need to multiply each possible outcome by its probability and then sum them up. In this case, the possible outcomes are winning $1000 with probability 1/1000 and losing $1 with probability 999/1000. So, the expected value is: ($1000 × 1/1000) + (-$1 × 999/1000) = -$0.999

Therefore, the expected value is approximately -$0.999. This means that, on average, you can expect to lose about $0.999 for each ticket you buy.

The values of price p for the product to remain profitable must be less than 1 and 25.

The value of P that will maximize the profit is 13.

For the given product to remain profitable, the revenue must continue to be greater than the cost that is R(p) > C(p)

Given the following parameters:

If R(p) > C(p), then;

[tex]- p^2+ 30p>4p+25\\p^2-26p+25<0[/tex]

Factorize to get the value of p

[tex]p^2-p-25p+25<0\\p(p-1)-25(p-1)<0\\(p-1)(p-25)<0\\p<1 \ and \ p<25[/tex]

Hence the values of price p for the product to remain profitable must be less than 1 and 25

To maxmimize the profit, dP/dp = 0

Profit = Revenue - Cost

Profit = [tex]- p^2+ 30p - 4p - 25[/tex]

Profit = [tex]-p^2+26p-25[/tex]

Differentiate the function and equate to zero;

[tex]dP/dp = -2p+26\\-2p + 26 = 0\\-2p = -26\\p=13[/tex]

Hence the value of P that will maximize the profit is 13

Trust me on this its the right answer I had the same question and got it correct!

Answer:- A) is the right answer.[tex]7\times10^{10}[/tex] is 50 times larger than [tex]13\times10^{8}[/tex]

Explanation:-

To estimate the number of times [tex]7\times10^{10}[/tex] is larger than [tex]13\times10^{8}[/tex]

Let [tex]7\times10^{10}[/tex] is larger than [tex]13\times10^{8}[/tex]  by n times.

then [tex]7\times10^{10}[/tex]  [tex]=n\times13\times10^{8}[/tex]

[tex]\Rightarrow\ n=\frac{7\times10^{10}}{13\times10^{8}}\\\\\Rightarrow\ n=\frac{7\times10^{10-8}}{13}.......[by\ law\ of\ exponents\ \frac{a^m}{a^n}=a^{m-n}]\\\\\Rightarrow\ n=\frac{7\times10^2}{13}\\\\\Rightarrow\ n=\frac{7\times100}{13}\\\\\Rightarrow\ n=\frac{700}{13}=53.84\approx50[/tex]

[as 53.84 is near to 50 by rounding off it to the nearest ten it becomes 50]

Thus [tex]7\times10^{10}[/tex] is 50 times larger than [tex]13\times10^{8}[/tex]
