Answer:

See below

Step-by-step explanation:

Two lines are parallel if they have the same slope but different y-intercepts. So the slope that can be formed given the points (-3,6) and (9,2) is (9-(-3))/(2-6)=12/-4=-3

With y=-3x+b, we need b, which can be found by plugging in either point:

2=-3(9)+b

2=-27+b

29=b

So the y-intercept therefore cannot be 29 but it can be any real number.

So the equation y=-3x+2 works, y=-3x+3, y=-3x+4, and so on....

Answer: The first question (How much volume is left after 10 minutes) is C or 3,019.92 cubic millimeters. The second question (About how many minutes will it take for the icicle to completely melt? Round to the nearest tenth) is B or 50.3 minutes.

Step-by-step explanation:

It will take 50.2 minutes for the icicle to completely melt.

How to Find out how many minutes will it take for the icicle to completely melt? Round to the nearest tenth.

Given that An icicle has a volume of 3,7369.91 mm3.

If the icicle drips at a rate of 75 mm3 per minute

then the full volume of 3,769.91 mm3 drips at = 3,769.91mm^3/75mm^3

=> 50.2654 mins.

which is equal to 50.2 to the nearest 10th.

Answer:

second picture

Step-by-step explanation:

The rule to rotate a point counterclockwise about the origin is:

Or in words, we switch the coordinates of the point and change the sign of the y-coordinate.

We know from the first picture that the coordinates of our quadrilateral ABCD are A = (-1, 0), B = (0, -1), C = (-2, -3), and D = (-3 , -2), so let's apply the rotation rule to each one of those points:

Now we know that the coordinates of the quadrilateral after a rotation of 90° are A' = (0, 1), B' = (1, 0), C' = (3, -2), and D' = (2, -3), which corresponds to the second picture

Answer:

180 centimeters

Step-by-step explanation:

First, you have to make these into 2 different shapes. Two different prisms. You can see all the dimensions on the right shape, but not the left. How do you know the width? Well, since the width is the same for the WHOLE figure, the width for both shapes is the same. To find the volume of a rectangular prism, you need to multiply the length, width, and height.

Length * height * width

Shape 1: [tex]8 * 3 * 5 = 120[/tex] cm

Shape 2: [tex]2*6*5=60[/tex] cm

Then, you add the volumes of the 2 shapes to get the final volume.

120 + 60 = 180 cm

The equation of the line that is perpendicular to y = 4x - 10 and passes through the point (-16, 2) is y = -1/4x - 2, which is option A.

The student is asking for the equation of a line that is perpendicular to the given line y = 4x - 10 and passes through the point (-16, 2). The slope of the given line is 4, and the slope of a line perpendicular to it will be the negative reciprocal, which is -1/4. Using the slope-intercept form of a line, y = mx + b, where m is the slope and b is the y-intercept, we substitute the slope -1/4 and the point (-16, 2) to find b.

Plugging in the point, we get:

2 = (-1/4)(-16) + b

2 = 4 + b

b = 2 - 4

b = -2

So, the equation of the line is y = (-1/4)x - 2. The correct answer is option A) y = -1/4x - 2.

To find the line perpendicular to ( y = 4x - 10 ) passing through (-16, 2), its equation is[tex]\( y = -\frac{1}{4}x - 2 \)[/tex], option A.

The correct option is a)[tex]\(y = -\frac{1}{4}x - 2\).[/tex]

To find the equation of the line that is perpendicular to the given line (y = 4x - 10), we first need to determine the slope of the given line, because perpendicular lines have slopes that are negative reciprocals of each other.

The given line (y = 4x - 10) is in the slope-intercept form (y = mx + b), where (m) is the slope. In this case, the slope of the given line is (m = 4).

The negative reciprocal of (4) is [tex]\(-\frac{1}{4}\)[/tex]. This will be the slope of the perpendicular line.

Now, we use the point-slope form of a line, which is [tex]\(y - y_1 = m(x - x_1)\),[/tex]where [tex]\((x_1, y_1)\)[/tex] is a point on the line and \(m\) is the slope.

Given the point ((-16, 2)), we substitute (x_1 = -16) and (y_1 = 2) into the point-slope form and the slope[tex]\(m = -\frac{1}{4}\):[/tex]

[tex]\[ y - 2 = -\frac{1}{4}(x - (-16)) \][/tex]

[tex]\[ y - 2 = -\frac{1}{4}(x + 16) \][/tex]

Now, we can simplify and rewrite this equation in slope-intercept form (y = mx + b):

[tex]\[ y - 2 = -\frac{1}{4}x - 4 \][/tex]

[tex]\[ y = -\frac{1}{4}x - 4 + 2 \][/tex]

[tex]\[ y = -\frac{1}{4}x - 2 \][/tex]

So, the equation of the line that is perpendicular to (y = 4x - 10) and passes through the point ((-16, 2)) is option A) [tex]\(y = -\frac{1}{4}x - 2\).[/tex]

105 = 10 x 10 x 10 x 10 x 10 = 100,000 (5 zeros)

108 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 100,000,000 (8 zeros)

Notice that the number of zeros in the ordinary decimal expression is exactly equal to the power to which 10 is raised.

If the number is expressed in words, first write it down as an ordinary decimal number and then convert. Thus, "ten million" becomes 10,000,000. There are seven zeros, so in powers of ten notation ten million is written 107.

A number which is some power of 1/10 can also be expressed easily in scientific notation. By definition,

1/10 = 10-1 ("ten to the minus one power")

More generally, the expression "10-n" (where n is a whole number) means ( 1/10 )n. Thus

10-3 = ( 1 / 10 )3 = 1 / ( 10 x 10 x 10) = 1/1000

10-8 = ( 1 / 10 )8 = 1/100,000,000

The probability of selecting a freshman or a sophomore from the French class is 0.9 or 90%. The probability of selecting a freshman or a sophomore from the French class can be found by dividing the total number of freshmen and sophomores (18) by the total number of students (20). The probability is calculated as 18 / 20, which simplifies to 0.9 or 90%.

To find the probability of selecting a freshman or a sophomore from the French class, we need to calculate the total number of freshmen and sophomores and divide it by the total number of students.

Step 1: Calculate the total number of freshmen and sophomores.

The total number of freshmen is 10, and the total number of sophomores is 8. Adding these two numbers together, we get 10 + 8 = 18.

Step 2: Calculate the total number of students.

The total number of freshmen, sophomores, and juniors is given as 10 + 8 + 2 = 20.

Step 3: Calculate the probability.

The probability of selecting a freshman or a sophomore can be calculated by dividing the total number of freshmen and sophomores (18) by the total number of students (20).

P(freshman or sophomore) = Number of freshmen and sophomores / Total number of students

P(freshman or sophomore) = 18 / 20

P(freshman or sophomore) = 0.9

Therefore, the probability of selecting a freshman or a sophomore from the French class is 0.9 or 90%.

The question probable may be:

What is the probability of selecting a freshman or a sophomore from the French class, and how is this probability calculated using the total number of freshmen and sophomores divided by the total number of students?

I put the equation into a GeoGebra graphing calculator, and y=sin(x-2) matches the graph.

The function represents the given graph is y = sin(x - 2).

"Translating a graph means that moving it along the x or y axis by certain units."

1) For a function of the type y = f(x) + k

If k > 0, the graph of y = f(x) will translate up(along positive Y-axis) by k units.

If k < 0, the graph of y = f(x) will translate down(along negative Y-axis) by k units.

2) For a function of the type y = f(x + m)

If m > 0, the graph of y = f(x) will translate left(along negative X-axis) by m units.

If m < 0, the graph of y = f(x) will translate right(along positive X-axis) by m units.

From given example,

The function represents the given graph is y = sin(x - 2).

This means, the function y = sin(x) is translated right by angle 2 (degrees / radians) as shown in the following figure.

To figure out how much the game costs in total, we first need to divide $36 by 3 (3 is the numerator).

36 / 3 = 12

The number 12 is how much each quarter is worth as shown below.

1/4 = 12

2/4 = 24

3/4 = 36

4/4 = ?

To find the answer, all we do is add 12 to 36.

12 + 36 = $48

Answer:
