The interest Pedro will have to pay is $5200

From the question, we have the following parameters that can be used in our computation:

Principal = $32.500

Rate = 4% simple interest

Time = 4 years

The formula of simple iinterest is

I = Principal * Rate * Time

substitute the known values in the above equation, so, we have the following representation

I = 32500 * 4% * 4

Evaluate

I = 5200

Answer:

A

Step-by-step explanation:

Slope intercept form is y = mx + b

First find the slope or m with this equation \(\frac{y2 - y1}{x2 - x1}\) (plug in) \(\frac{6 - 2}{12 + 4}\) = \(\frac{4}{16}\)=  \(\frac{1}{4}\)

So your slope is \(\frac{1}{4}\)

To find the y-intercept you use y= mx + b and plug in.

6 = 1/4(12) + b

6 = 3 + b (minus 3 on both sides)

3 = b

so 3 is the y-intercept

So the answer is A.

Answer:

To solve the equation:

2/3x - 1/5x = x - 1

First, we need to find a common denominator for 2/3 and 1/5, which is 15. So we can rewrite the equation as:

(10/15)x - (3/15)x = 15/15 x - 1

Simplifying the left side:

(7/15)x = 15/15 x - 1

Multiplying both sides by 15:

7x = 15x - 15

Subtracting 7x from both sides:

-8x = -15

Dividing both sides by -8:

x = 15/8 or 1.875

Therefore, the solution to the equation is x = 1.875.

Okay so you put -6 in where y is then solve and youll get your answer

-8x-7(-6)=-6

The coordinates of the midpoints of the given line segment is:

(3.5, 1.5)

The midpoint of a line segment is simply referred to as the center of that specific line segment.

Thus, the coordinates at that point will be referred to as the coordinates of the midpoint.

The coordinates of the endpoints of the line are:

(4,6) and (3,-3)

The formula to find the coordinates of the midpoint of the line is:

(x, y) = (x₁ + x₂)/2, (y₁ + y₂)/2

Thus, we have:

(x, y) = (4 + 3)/2, (6 - 3)/2

= (3.5, 1.5)

Step-by-step explanation:

Let

Z---------------- > number of zacks stamps collections  for a stamp show

T---------------- > number of teri's stamps collections  for a stamp show

P--------------- > number of pacos  stamps collections  for a stamp show

we know that

Z=(3/10)*30-----------> Z=9

T=(5/6)*18------------ > T=15

P=(3/8)*24------------->P=9

the answer is

number of zacks stamps collections  for a stamp show was 9

number of teri's stamps collections  for a stamp show was 15

number of pacos  stamps collections for a stamp show was 9

In their display were 33 stamps

well, the profit is clearly just 490 - 350 = 140.

Now, if we take 350(origin amount) to be the 100%, what is 140 off of it in percentage?

\(\begin{array}{ccll} Amount&\%\\ \cline{1-2} 350 & 100\\ 140& x \end{array} \implies \cfrac{350}{140}~~=~~\cfrac{100}{x} \\\\\\ \cfrac{5}{2} ~~=~~ \cfrac{100}{x}\implies 5x=200\implies x=\cfrac{200}{5}\implies x=40\)

Answer:

2 < y < 6

Step-by-step explanation:

Expand the brackets, multiplying by y

12 < 8y - y^2

Rearrange

0 < -y^2 + 8y - 12

Divide by -1. When dividing by a negative number, you must flip the inequality sign

0 > y^2 - 8y + 12

Factorise

0 > (y - 6)(y - 2)

The two solutions are y = 6, 2

Check using a value inbetween 2 and 6 to see if the inequality holds true. For example 3 is between 2 and 6

0 > (3 - 6)(3 - 2)

0 > -3(1)

0 > -3

As this holds true, this means that y lies between 2 and 6

Therefore, the answer is 2 < y < 6

(If the inequality did not hold true, then y would lie above 6 and below 2. y < 2 and y > 6. Not relevant for this example)

Answer with Step-by-step explanation:

you basically have to prove similarity, then use that to prove the two angles CDE & DAB are equal. You can prove similarity with AA, SSS, or SAS.

The relationship between the depth(d), the base area (b) and volume (V) is d = 2400/b

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

Let d represent the depth of the tank, b represent the area of the base and V represent the volume.

The depth of water is inversely proportional to the area of its base at constant volume. Hence

d = V/b

When b = 200 ft² and d = 12:

12 = V/200

V = 2400

d = 2400/b

Answer:

$33.48

Step-by-step explanation:

The five-number summary for this data set is 29, 32, 43.5, 50.5, and 53, and the interquartile range is 18.5.

Measures of statistical dispersion, or the spread of the data, include the interquartile range. In addition to the IQR, other names for it include the midspread, middle 50%, fourth spread, and H-spread.

To find the five-number summary and interquartile range for this data set, we first need to find the quartiles.

Step 1: Find the median (Q2)

When a data collection is sorted from least to largest, the median is the midway value. Since there are 12 values in this data set, the median is the average of the sixth and seventh values:

Median (Q2) = (41 + 46)/2 = 43.5

Step 2: Find the lower quartile (Q1)

The lower quartile is the median of the lower half of the data set. Since there are 6 values below the median, we take the median of those values:

Q1 = (32 + 32)/2 = 32

Step 3: Find the upper quartile (Q3)

The upper quartile is the median of the upper half of the data set. Since there are 6 values above the median, we take the median of those values:

Q3 = (50 + 51)/2 = 50.5

Now we have all the information we need to construct the five-number summary and interquartile range:

Minimum: 29

Lower quartile (Q1): 32

Median (Q2): 43.5

Upper quartile (Q3): 50.5

Maximum: 53

Interquartile range (IQR) = Q3 - Q1 = 50.5 - 32 = 18.5

the five-number summary for this data set is 29, 32, 43.5, 50.5, and 53, and the interquartile range is 18.5.

Answer:

The point at f(-3) is at (-3,1).

Step-by-step explanation:

To find the y-value of a function at a specific point by using the graph, keep in mind that the x-axis is the axis that lies horizontally on the graph.

So, look along the horizontal line through the center until you find where x = -3. Now find the corresponding y-value to that x-value by looking above or below that point until you find where it intersects the graph. When you find that point, look to see what number the point corresponds with on the y-axis. In this case, it corresponds to y = 1.

Remember that ordered pairs are formatted as (x,y).

Answer:

I suppose it has 4 digits.

Step-by-step explanation:

The fractional equivalent of the repeating decimal would be 15/99.

Step-by-step explanation:

any linear function represents a straight line (hence the name) and is therefore of the structure

y = f(x) = ax + b

"a" is the slope of the line, and it is represented by the ratio (y coordinate difference / x coordinate difference) when going from one point on the line to another point.

"b" is the y-intercept (the y-value when x = 0).

so, let's look at the answer options :

A.

x = 0 gives us b (the y value) : 2

so, then for x = 1, y = 3 ?

3 = a×1 + 2

a = 1

now, the next point must be also on the same line for the whole function to be linear (and that means the equation has to be true for all numbers involved) :

x = 2, y = 6

6 = 1×2 + 2 = 4

6 is for sure NOT 4, so this is not a linear function.

it is actually y = x² + 2

B.

x = 0 gives us b : 1

for x = 1, y = 3 ?

3 = a×1 + 1

a = 2

again, the next point must be on the same line :

x = 2, y = 9

9 = 2×2 + 1 = 5

9 is for sure NOT 5, so this is not a linear function.

it is actuality y = 3^x.

C.

x = 0 gives us b : 0

for x = 1, y = 1 ?

1 = a×1 + 0 = a

a = 1

the next point :

x = 2, y = 4

4 = 1×2 = 2

4 is for sure NOT 2, so this is not a linear function.

it is actually y = x².

D.

x = 0 gives us b : 3

for x = 1, y = 9

9 = a×1 + 3

a = 6

the next point(s) must fit :

x = 2, y = 15

15 = 6×2 + 3 = 12 + 3 = 15

correct

x = 3, y = 21

21 = 6×3 + 3 = 18 + 3 = 21

correct

yes, this is a linear function.

it is y = 6x + 3

Pixel size for fast spin echo is 0.94mm x 0.94mm. FOV 30cm, TR 600, TE 10, 320x320 matrix, 4NEX, 3mm slice thickness, 3ETL.

To calculate the pixel size, we first need to convert the FOV from 30cm to 300mm. We can then divide the FOV by the matrix size (320 x 320) to get the pixel size. This will give the same value for both the phase dimension and frequency dimension pixels. So the pixel size for the fast spin echo sequence is 0.94mm x 0.94mm.

The other parameters for the sequence are TR 600, TE 10, 4NEX, 3mm slice thickness and 3ETL. These parameters will determine the type of sequence and the overall image quality. With these parameters, the fast spin echo sequence should produce a high quality image with good resolution.

The graph which represents the polar curve r = -4 sin ( 3θ ) is plotted

Polar coordinates describe the position of a point P in the plane by its separation from the origin, r, and the angle formed between the positive x-axis and the line segment leading to P.

To graph the polar curve, we make use of the following representations:

r represents the y-axis

θ represents the x-axis

Polar coordinates can also be extended into three dimensions using the coordinates (ρ, φ, θ), where ρ is the distance from the pole, φ is the angle from the z-axis ( called the co-latitude or zenith and measured from 0 to 180° ) and θ is the angle from the x-axis ( as in the polar coordinates ).

Given data ,

Let the polar curve be represented as A

Now , the polar coordinates is given as

r = -4 sin ( 3θ )

And , To graph the polar curve, we make use of the following representations:
