x 3(x 2 + 5x + 1)
The required product of expression x³(x² + 5x + 1) is x⁵ + 5x⁴ + x³.
The distributive property of multiplication (also known as the distributive property of product over addition) is a fundamental property of arithmetic that helps simplifyexpressions involving multiplication and addition. It states that for any three numbers a, b, and c:
a * (b + c) = a * b + a * c
Here,
We can use the distributive property of multiplication to expand the product:
x³(x² + 5x + 1) = x³x² + x³5x + x³*1
Simplifying each term, we get:
x³x² = x³⁺² = x⁵
x³5x = 5x¹⁺3 = 5x⁴
x³*1 = x³
Setting it all together, we have:
x³(x² + 5x + 1) = x⁵ + 5x⁴ + x³
Therefore, the product is x⁵ + 5x⁴ + x³.

y = (x + 3)^2
y = x^2 - 3
y = x^2 + 3
Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
We need a parabola with a vertex at (0,-3)
If we select the equation:
When we put x = 0, we get
And similarly, when we put y = -3, we get
Hence, third option is correct.
Answer:
Graph
Step-by-step explanation:
The simplest way to graph a linear equation is to make an x, y chart.
Plug in values for x ( 3 values for x works ), then find the y values and graph the cordinates.
Another way to graph the above line is to identify the slope and the y-intercept. Because the function is in slope-intercept form, we can readily see both ( slope intercept form is y= mx + b where m= slope and b= y-intercept )! So b= 75 and m= 15. So to graph the y-intercept, it is ( 0, b ) and just count the slope from that point!
To graph the equation y = 15x + 75, start by plotting the y-intercept (0,75). Then move 15 units up and 1 to the right from the intercept. Connect the points to create the graph.
To graph the equation y = 15x + 75, you need to recognize it as the linear equation in slope-intercept form, y = mx + b. In this equation, m (slope) is 15 and b (y-intercept) is 75.
Start by plotting the y-intercept which is at the point (0, 75) on the y-axis. Then, from that initial point, use the slope or 'rise over run,' to find the next points. Given the slope is 15 (or 15/1), you will go up 15 units and right 1 unit from the intercept to plot your next point. Continue this process until you have enough points to produce a straight line.
By connecting these plotted points, you create the graph of y = 15x + 75.

Answer:
The risk premium is positive, indicating a preference for certainty over risk.
Step-by-step explanation:
The risk premium is a measure of how much someone is willing to pay to avoid a risky situation or to insure against potential losses. It is the difference between the expected value of a gamble (or lottery) and the guaranteed (certain) outcome.
In this case, you're dealing with a decision maker who has initial wealth of 4 and faces the following lottery:
Option A: A loss of 2 with a probability of 1/2
Option B: A gain of 2 with a probability of 1/2
Let's calculate the expected value of this lottery:
Expected Value (EV) = (Probability of Option A) * (Value of Option A) + (Probability of Option B) * (Value of Option B)
EV = (1/2) * (-2) + (1/2) * (2)
EV = -1 + 1
EV = 0
The expected value of this lottery is 0. This means that, on average, the decision maker doesn't expect to gain or lose wealth; it's a fair game in terms of expected value.
Now, to calculate the risk premium, we compare this lottery to a certain outcome. In this case, the certain outcome is keeping the initial wealth of 4.
Risk Premium = Guaranteed Outcome - Expected Value of Lottery
Risk Premium = 4 - 0
Risk Premium = 4
The risk premium is 4, which means that the decision maker is willing to pay up to 4 to avoid taking this lottery. This is because the lottery is a risky proposition, and the decision maker values the certainty of keeping their initial wealth at 4 over the gamble, even though, on average, the gamble doesn't result in a gain or loss. Therefore, the risk premium is positive, indicating a preference for certainty over risk.
