Draw the image of ∆PQR after a rotation of 180° about the origin. Label the image ∆P'Q'R'.
Draw the image of ∆PQR after a reflection across the x-axis. Label the image ∆P"Q"R".
To obtain the image of triangle ∆PQR after a 180° rotation about the origin, we applied the rotation formula to each vertex, resulting in the new coordinates P'(-1, 1), Q'(-3, 2), and R'(-3, 4). Connecting these points forms the rotated triangle ∆P'Q'R'.
To draw the image of triangle ∆PQR after a 180° rotation about the origin, we'll need to find the new coordinates of the vertices P', Q', and R'. The general formula for rotating a point (x, y) by 180° about the origin is to negate both the x and y coordinates, resulting in the point (-x, -y). Let's apply this formula to each vertex:
Vertex P(1, -1) is rotated to P'(-1, 1).
Vertex Q(3, -2) is rotated to Q'(-3, 2).
Vertex R(3, -4) is rotated to R'(-3, 4).
Now, we have the new coordinates for the vertices of the rotated triangle ∆P'Q'R'. Let's plot these points on a coordinate plane:
P'(-1, 1)

| Q'(-3, 2)

R'(-3, 4)
The triangle ∆P'Q'R' is formed by connecting these three points, and it is the image of ∆PQR after a 180° rotation about the origin.

Mazie Invested $4500 in an account earning 4.3% interest compounded continuously. After how many years will she have $7400 in her account
The question is about continuous compound interest in finance. Given initial investment, final amount, and interest rate, we utilize the formula for continuous compound interest to calculate how many years it will take for the investment to reach a certain value.
Explanation:The subject in this question is interest compounding in mathematics, specifically in the field of finance. Compounding continuously involves the application of the formula for continuous compound interest, which is A = P*e^(rt), where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).e is the base of the natural logarithm, approximately equal to 2.71828.r is the annual interest rate (in decimal).t is the time the money is invested or borrowed for, in years.In Mazie's case, we have P=$4500, A=$7400, and r=4.3% or 0.043 in decimal form. We're solving for t, the time. Therefore, by substitution, we have 7400=4500*e^(0.043t). Solving for 't' will provide us the number of years it takes for the account to grow to $7400.

Bill spends two days driving from point a to point
b. on the first day, he drove 2 hours longer and at an average speed 5 miles per hour faster than he drove on the second day. if during the two days he drove a total of 680 miles over the course of 18 hours, what was his average speed on the second day, in miles per hour?
Answer: his average speed on the second day is 35 miles per hour
Step-by-step explanation:
Bill spends two days driving from point a to point b
Let x = his speed on the first day.
Let y = his speed on the second day
Speed = distance / time
Time = distance / speed
Total time spent on the trip is 18 hours
Let time that he spent on the first day be t hours
Time that he spent on the second day will be 18 - t
Bill drove 2 hours longer on the second day than on the first day. This means
t = 18 - t + 2
t+t = 18+2
2t = 20
t = 10
He spent 10 hours on the first day.
He spent 18-10 = 8hours on the second day.
Bill drove at an average speed of 5 miles per hour faster than he drove on the second day. This means that
x = y + 5 - - - - - - - -- 1
Distance travelled on the first day = speed on the first day × time spent. This becomes
10 × x = 10x miles
Distance travelled on the second day = speed on the second day × time spent. This becomes
8 × y = 8y miles
He drove a total of 680 miles over the course of the 18 hours. This means that
10x + 8y = 680 - - - - - - - - 2
Substituting equation 1 into equation 2, it becomes
10(y + 5) + 8y = 680
10y + 50 + 8y = 680
10y + 8y = 680 - 50
18y = 630
y = 630/18 = 35 miles per hour
x = y + 5 = 35 + 5
x = 40 miles per hour

Two events e and f are __________ if the occurrence of event e in a probability experiment does not affect the probability of event f.
Two events are independent if the occurrence of one event does not affect the probability of the other event.
Explanation:Two events are independent if the occurrence of one event does not affect the probability of the other event. This means that the outcomes of the two events are not related and the probability of one event happening does not change based on whether the other event occurred or not.
For example, if you flip a coin and roll a die, the outcome of the coin flip does not affect the probability of getting a certain number on the die roll. The two events are independent.

Megan is checking her tax bill for the last year.
The tax rates were as follows;
-no tax on the first £11 000 of earnings
Final answer:
Marginal tax rate refers to the tax rate applied to each additional dollar of income. Individuals pay according to the bracket their income falls into, with higher rates applying only to income that exceeds certain thresholds. An example includes a single taxpayer earning $35,000 a year being in the 15% marginal tax rate bracket.
Explanation:
The student's question relates to understanding marginal tax rates and how they apply to an individual's income. Marginal tax rate is the tax rate incurred on each additional dollar of income, meaning as you earn more, you generally pay a higher tax rate on your incremental earnings beyond certain thresholds. However, it's important to note that lower tax rates apply to lower income brackets, meaning individuals pay progressively more only on the income that falls within higher brackets.
For instance, consider the marginal tax rate structure where the first $9,075 of income is taxed at 10%, the income from $9,075 to $36,900 at 15%, and income beyond $36,900 at 25%. If a single taxpayer earns $35,000 a year, their marginal tax rate is 15% because their last dollar earned falls into the 15% tax bracket. However, not all their income is taxed at 15%; the income up to $9,075 is taxed at 10%, and only the income over $9,075 up to $35,000 is taxed at 15%.

suppose you roll a red number cube and a blue number cube. what is the probability that you will roll a 5 on the red cube and a 1 or a 2 on the blue cube?
The probability that you will roll a 5 on the red cube and a 1 or a 2 on the blue cube will be 1/18.
What is mean by Probability?
The term probability refers to the likelihood of an event occurring.
Given that;
You will roll a 5 on the red cube and a 1 or a 2 on the blue cube.
Now,
Sides of cube dice = 6
Hence, For red cube;
P (r) = 1/6
And, For blue red;
P (B₁ or B₂) = P(B₁) + P (B₂)
= 1/6 + 1/6
= 1/3
Thus, The probability that you will roll a 5 on the red cube and a 1 or a 2 on the blue cube = 1/6 x 1/3
= 1/18
Therefore, The probability that you will roll a 5 on the red cube and a 1 or a 2 on the blue cube will be 1/18.

You make skateboard ramps by cutting pieces from a board that is 12 1/2 feet long.
a. your friend estimates you can cut 6 ramps from the board. is her estimate reasonable? explain. how many ramps can you cut from the board? how much wood is left over?
The estimate of cutting 6 ramps from a 12 1/2 feet long board is reasonable. Each ramp will have a length of 2 1/12 feet, and no wood will be left over.
Explanation:To determine if the estimate of cutting 6 ramps from a 12 1/2 feet long board is reasonable, we can calculate the length of each ramp by dividing the total length of the board by the number of ramps.
12 1/2 feet is equivalent to 12 + 1/2 feet. To divide by a fraction, we can multiply by the reciprocal. So, when we divide 12 1/2 by 6, we get (12 + 1/2) / 6 = 12/6 + 1/2 / 6 = 2 feet + 1/12 feet = 2 1/12 feet.
Therefore, each ramp will have a length of 2 1/12 feet. Since 6 ramps multiplied by 2 1/12 feet is 12 1/2 feet, the estimate is reasonable. No wood will be left over.
The cube of a positive number divided by the square of the same positive number
The cube of a positive number divided by its square simplifies to the number itself, based on the exponent subtraction rule in algebra.
Explanation:The question involves a mathematical concept where the cube of a positive number is divided by the square of the same number. Mathematically, if we denote the positive number as 'x', then the expression would be x3/x2. According to the laws of exponents, when we divide two powers with the same base, we subtract the exponents. Thus, x3/x2 = x3-2 = x. This implies that the cube of 'x' divided by the square of 'x' simplifies to just 'x'. This is a fundamental mathematical operation under the topic of exponentiation and simplification of algebraic expressions.
