Answer:

(7,-2)

Step-by-step explanation:

First, you move to the right of y-axis like 5 to 7,

then you movie to the up of x-axis like -5 to -2.

So the answer was (7,-2)

Final answer:

The image point of (5,-5) after a translation right 2 units and up 3 units is (7, -2).

Explanation:

The image point of (5,-5) after a translation right 2 units and up 3 units can be found by adding the respective translation values to the x and y coordinates of the original point. To move the point right by 2 units, you add 2 to the x-coordinate, and to move the point up by 3 units, you add 3 to the y-coordinate.

Therefore, the new coordinates after the translation will be:

So the image point after the translation is (7, -2).

Answer:

64 cubes

Step-by-step explanation:

The square is 12x12x12 inches, meaning it is 1,728 cubic inches in volume. A 3x3x3 inch cube is 27 cubic inches in volume. Divide 1,728 by 27 and you'll find that 64 3x3x3 cubes can fit inside one of the 12x12x12 cubes.

Final answer:

To fill a cube-shaped container with an edge length of 12 inches, 64 small cubes with an edge length of 3 inches each are required.

Explanation:

The student is asking how many small cubes, with an edge length of 3 inches, are required to fill a larger cube-shaped container with an edge length of 12 inches. First, we calculate the volume of the large cube which is 12 inches x 12 inches x 12 inches, resulting in 1728 cubic inches. Then, we find the volume of one small cube which is 3 inches x 3 inches x 3 inches, resulting in 27 cubic inches. To determine the number of small cubes that can fit into the larger cube, we divide the large cube's volume by the small cube's volume: 1728 cubic inches / 27 cubic inches which equals 64. Therefore, 64 small plastic cubes are needed to fill the container.

His tank contains 8 gallons

He spends 16.50 on gas

A gallon of gas costs 1.50 dollars

Millage = 30 mpg

Find the gas added.

Total gas (in gallons) added = amount spent / cost per gallon

Total gas (in gallons) added = 16.50 / 1.50

Total gas (in gallons) added = 11 gallons.

Find the total number of gallons in his tank.

Total = what was there + What he bought.

Total = 8 + 11

Total = 19 gallons.

Find the distance he can travel

Total distance = gallons * miles / gallon

Total distance = 19 * 30

Total distance = 570 miles.

Tyler and Statton could potentially travel a total distance of 570 miles with the amount of gas they have.

The question is asking for the total distance that the boys could travel on the bought gas. Tyler bought $16.50 worth of gas at $1.50 per gallon, which means he bought 11 gallons ($16.50/$1.50). Tyler initially had 8 gallons of gas in his tank. Therefore, he now has a total of 8 + 11 = 19 gallons of gas. His Jeep gets 30 miles for every gallon of gas. Therefore, the total distance they can travel is 19 gallons * 30 miles/gallon = 570 miles.

So, "Tyler and Statton could potentially travel 570 miles with the gas in the tank".

Answer:   [tex]x \ge 3[/tex] (choice D)

===========================================

Explanation:

Saying "a minimum of 3" means that the lowest you can go is 3. You can pick 3 or pick any value larger than this. Therefore we can say that x is greater than or equal to 3.

The correct mathematical translation for 'It is a minimum of three.' is 'x ≥ 3'. This means that 'x' can be three or any number greater than three.

The correct translation for the English statement 'It is a minimum of three.' is x ≥ 3. This means 'x' can be equal to three or any number greater than three.

This is because in mathematical language, the term 'minimum' refers to the lowest possible value that a variable like 'x' can take. Since it's specified that 'x' has a minimum value of three, it can't be less than three.

The notation 'x ≥ 3' effectively means that 'x' is equal to three or 'x' is greater than three, which fits the criteria that it's a minimum of three.

here are the answers to this question

Answer:

The zeroes are {-4, 13}

Step-by-step explanation:

Your best bet here is to determine the zeros using the quadratic formula or "completing the square."

Completing the square,

y = x² - 17x                         +52, or

y = (x - 17/2)² - (17/2)²         +52, or

y = (x - 17/2)² - 289/4          +208/4, or

y = (x - 17/2)²  - 81/4

We set this = to 0, as we want the zeros.  Then:

(x - 17/2)²  - 81/4 = 0, or

x - 17/2 = ±9/2, after having taken the square root of both sides.

Thus, one root is x = 17/2 + 9/2, or 26/2, or 13, and the other is

                             x = 1/2 - 9/2, or -8/2, or -4.

The zeroes are {-4, 13}.

Answer: 27/12 or 2 3/12

Step-by-step explanation: First off we would need to find a common denominator, so all the fractions could be added together easily, and we could use a denominator of 12 because 6 times 2 equals 12, 4 times 3 equals 12, and 3 times 4 equals 12. So 5/6 would become 10/12, 3/4 would become 9/12, and 2/3 would become 8/12. So adding them all together would give you a sum of 27/12 or 2 3/12. Hope this helped!

Final answer:

The probability of getting a 2 and then a 1, given that the first number rolled was 2, is 1/5 or 0.2 (20%).

Explanation:

The probability of getting a 2 and then a 1, given that the first number rolled was 2, can be calculated using the concept of conditional probability.

Since we know that the first number rolled was a 2, the sample space is reduced to {2, 3, 4, 5, 6}. The probability of rolling a 2 from this reduced sample space is 1/5.

Now, since we want to find the probability of rolling a 1 after rolling a 2, the reduced sample space is further reduced to {1}. The probability of rolling a 1 from this reduced sample space is 1/1, since there is only one outcome.

Therefore, the probability of getting a 2 and then a 1, given that the first number rolled was 2, is 1/5 * 1/1 = 1/5 or 0.2 (20%).

The probability of rolling a 2 and then a 1 on a six-sided number cube, given that the first number rolled was a 2, is [tex]\(\frac{1}{6}\)[/tex].

To solve this problem, we need to consider the probability of each event separately and then combine them, keeping in mind that the outcome of the first roll affects the probability of the second roll.

1. The probability of rolling a 2 on the first roll is [tex]\(\frac{1}{6}\)[/tex], since there is only one '2' on a six-sided die and there are six possible outcomes.

2. Given that the first roll is a 2, the probability of rolling a 1 on the second roll is still [tex]\(\frac{1}{6}\)[/tex]. This is because the die has no memory, and each roll is independent of the previous one. The fact that a 2 was rolled first does not change the probability of rolling a 1 on the second roll.

3. Since the rolls are independent events, we multiply the probabilities of the two events to find the combined probability:

[tex]\[ P(\text{2 and then 1} | \text{first roll is 2}) = P(\text{first roll is 2}) \times P(\text{second roll is 1}) \][/tex]

4. Substituting the probabilities we found:

[tex]\[ P(\text{2 and then 1} | \text{first roll is 2}) = \frac{1}{6} \times \frac{1}{6} \][/tex]

5. Multiplying these probabilities:

[tex]\[ P(\text{2 and then 1} | \text{first roll is 2}) = \frac{1}{36} \][/tex]

However, since we are given that the first number rolled was a 2, we do not need to consider the probability of rolling a 2 on the first roll. We only need to consider the probability of rolling a 1 on the second roll, which is [tex]\(\frac{1}{6}\)[/tex].

Therefore, the probability of getting a 2 and then a 1, given that the first number rolled was a 2, is [tex]\(\frac{1}{6}\)[/tex].

[tex](x_1,y_1)=(-4,-1)[/tex]

The measure of the angle between tangent and secant AB in a circle with arcs in a 1:5 ratio is 120°, calculated using arc measures.

Let's denote the measures of the arcs subtended by chord AB as x and 5x, where x is the measure of the smaller arc.

Now, according to the properties of angles formed by a tangent and a secant, the measure of the angle formed between the tangent and the secant AB is equal to half the difference of the measures of the intercepted arcs.

So, the measure of the angle [tex]\( \angle A \)[/tex] formed between the tangent and the secant AB is:

[tex]\[ \angle A = \frac{1}{2} \left|5x - x\right| \\\[ \angle A = \frac{1}{2} \left|4x\right| \][/tex]

Now, since x represents the measure of the smaller arc, it must be greater than 0. Thus, the expression simplifies to:

[tex]\[ \angle A = 2x \][/tex]

Now, we need to find the value of x. Since the sum of the measures of the arcs in a circle is 360°, we have:

[tex]\[ x + 5x = 360^\circ \\\[ 6x = 360^\circ \\\[ x = \frac{360^\circ}{6} \\\[ x = 60^\circ \][/tex]

Now, we can find the measure of the angle [tex]\( \angle A \)[/tex]:

[tex]\[ \angle A = 2x \\\[ \angle A = 2(60^\circ) \\\[ \angle A = 120^\circ \][/tex]

So, the measure of the angle between the tangent and secant AB is 120°.

Answer:

The measure of the angle between the tangent and secant AB is [tex]\(120\°\).[/tex]

Explanation:

To solve this problem, let's denote the measures of the two arcs subtended by chord AB as [tex]\(x\)[/tex]  and [tex]\(5x\)[/tex], respectively.

We know that when a tangent line intersects a secant line, the angle formed between the tangent and the secant is equal to half the difference of the measures of the intercepted arcs.

So, the angle between the tangent and secant AB, let's call it [tex]\(\theta\)[/tex], is given by:

[tex]\[ \theta = \frac{1}{2}(5x - x) = \frac{1}{2}(4x) = 2x \][/tex]

Now, let's find the value of [tex]\(x\).[/tex]

Since chord AB subtends two arcs with measures in the ratio of [tex]\(1:5\)[/tex], the total angle around the circle is [tex]\(1x + 5x = 6x\)[/tex], which is [tex]\(360\°\)[/tex](since the total angle around a circle is [tex]\(360\°\)[/tex]).

So, we have:

[tex]\[ 6x = 360\° \][/tex]

Solving for [tex]\(x\):[/tex]

[tex]\[ x = \frac{360\°}{6} = 60\° \][/tex]

Now, we can find the measure of the angle [tex]\(\theta\):[/tex]

[tex]\[ \theta = 2x = 2 \times 60\° = 120\° \][/tex]

So, the measure of the angle between the tangent and secant AB is [tex]\(120\°\).[/tex]

The rate of change on a graph represents how fast or slow the changes are happening, while the initial value is the starting point. To find these on a graph, you determine the slope of the line for the rate of change, and look at the intercept on the y-axis for the initial value. These values give us insights into the reading pace and starting point of the teacher.

The rate of change in a graph represents the slope of the line. It tells us how the quantity being measured changes over time. If the graph is a straight line, the rate of change is constant, but if the line is curved, the rate of change varies.

To find the rate of change, you need to select two points on the graph and find the difference in the page numbers divided by the difference in the corresponding time points. That is (pages end - pages start) / (time end - time start).

The initial value is the point where the teacher started reading the book. This point is seen as the intercept on the y-axis of the graph.

The interpretation of these values would be that the rate of change tells us how quickly the teacher is reading the book, and the initial value tells us at what page number the teacher started reading.

Initial value: The teacher initially read 150 pages. Rate of change: The teacher read 100 pages per day. The graph shows that the teacher is reading at a consistent pace and is making good progress on the book.

The initial value of the graph is the y-intercept, which is 100 pages. This means that the teacher had already read 100 pages before the graph starts.

The rate of change of the graph is the slope, which is calculated as (change in y) / (change in x). In this case, the slope is (750 - 100) / (5 - 1) = 130 pages/day.

This means that the teacher is reading 130 pages per day.

Interpretation:

The teacher is reading at a rate of 130 pages per day. This means that each day, the teacher is reading 130 more pages than the previous day.

The initial value of 100 pages means that the teacher had already read a significant portion of the book before the graph starts. It is possible that the teacher was reading ahead, or that the teacher was reading a chapter book to the class and had already finished the first chapter.

Overall, the graph shows that the teacher is reading at a consistent pace and is making good progress on the book.
