The correct expIanation is B. When 7 3 8 is muItipIied by a number greater than 1, the product is Iess than 7 3 8.

A fraction is a way of representing a part of a whoIe or a ratio between two quantities. It consists of a numerator (top number) and a denominator (bottom number) separated by a horizontaI Iine.

To compare the two fractions, we can convert them to decimaIs.

7 3/8 is equaI to 7.375, and

4/5 is equaI to 0.8.

MuItipIying 7.375 by 0.8, we get:

7.375 × 0.8 = 5.9

This means that 7 3/8 muItipIied by 4/5 is Iess than 7 3/8, since the product is 5.9 which is Iess than 7.375.

Therefore, the correct expIanation is B. When 7 3 8 is muItipIied by a number greater than 1, the product is Iess than 7 3 8.

The correct answer is f(m)=5230(1.015)m12.

A function is a self-contained block of code that takes inputs, performs specific operations on those inputs, and produces an output. It is a subprogram that performs a specific task, and helps to break down larger programs into smaller, more manageable pieces. Functions are also reusable, meaning that once a function is written, it can be used over and over again in different places in the program.

This function can be used to represent the student enrollment m months after the study began, as it takes into consideration the number of years (t) represented by the number of months (m) and incorporates it into the equation. The equation multiplies the number of months (m) by 12 to convert it into the number of years (t) used in the original equation, f(t)=5230(1.015)t. This ensures that the correct student enrollment is calculated based on the number of months since the study began.

Answer:

x=67
y=67
z=113

Step-by-step explanation:

Because this is a rhombus, that means that angle 113 and z are correlating, and angle y and x correlate. This is a four-sided shape, so the total of all four angles will add up to 360.

113 and z are correlating, so z is 113.

To find the other two, we first need to find out how much angle measurement is left. To do this, we will subtract angle 113 and z from 360 (our total).

This gives us 134 degrees left.

Now, since x and y are equal to each other, that means that their measurements will be exactly half of the remainder we just found.

So taking 134 and dividing it by 2, we get our final two measurements for x and y, 67 degrees each.

Answer:

x = 67

y = 67

z = 113

Work:

There are a total of 360 degrees in a rhombus and a straight line is 180 degrees. You also know that opposite angles in a rhombus are equal.

If z is opposite 113, then z = 113.

Then to find x, 180 - 113 = 67.

If x is 67 then y is 67 since they are opposite angles.

The measures of the angles in the parallel lines is

m∠a = 97°

m∠b = 15°

m∠c = 68°

m∠d = 68°

Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Consecutive Interior Angles

When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.

Given data ,

Let the two parallel lines be represented as l and m

Now , the transversal line is t

The measure of m∠a = 97° ( corresponding angles )

The measure of m∠d = 180° - 112° ( angles in a straight line = 180° )

So , the measure of m∠d = 68°

The measure of m∠c = measure of m∠d ( alternate interior angles )

So , the measure of m∠c = 68°

From the triangle formed by the intersection of lines ,

The measure of m∠b = 180° - ( a + d ) ( angles of a triangle = 180° )

So , the measure of m∠b = 180° - ( 97° + 68° )

The measure of m∠b = 15°

Hence , the measures of angles are solved

The probability and the likelihood, that the marble drawn is not red is high which is 4/5.

To determine how likely something is gonna occur, use probability. Several things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is. In the probability scale, 0 indicates an impossibility and 1 indicates a certainty.

It is stated that there is a 2/10 chance of drawing a red marble at random.

We can deduct the likelihood of drawing a red marble from one to determine the likelihood that the drawn marble is not red (since the probability of an event and its complement add up to 1).

So, the probability of drawing a marble that is not red is -

1 - 2/10 = 8/10 = 4/5

Therefore, the probability that the marble drawn is not red is 4/5.

The likelihood of an event is a measure of how plausible it is, given some evidence or knowledge.

In this case, we can say that the likelihood of drawing a marble that is not red is high, since there are more marbles in the jar that are not red than those that are red.

Therefore, the likelihood of drawing a marble that is not red is high.

Work Shown:

The notation f(-1) = 30 tells us that (x,y) = (-1,30) is a point on the exponential curve.

Plug in x = -1 and y = 30 and solve for 'a'

y = a*b^x

30 = a*b^(-1)

30 = a*(1/b^1)

30 = a/b

a = 30b

--------------------------------------------------

Now plug that into the equation to get

y = a*b^x

y = 30b*b^x

y = 30b^1*b^x

y = 30b^(1+x)

Afterward, plug in x = 4 and y = 85 to solve for b.

85 = 30b^(1+4)

85 = 30b^5

b^5 = 85/30

b = (85/30)^(1/5)

b = 1.23157122757057

We can then determine the value of 'a'

a = 30b

a = 30*1.23157122757057

a = 36.947136827117

--------------------------------------------------

To summarize,

both of which are approximate.

Since we want f(3) to the nearest hundredth, we don't really need to go too overboard with precision. Let's round 'a' and b to 4 decimal places.

We then get

This means

y = a*b^x

turns into

y = 36.9471*(1.2316)^x

As a check, plug in x = -1 to get y = 29.999269; we'll have rounding error since we rounded those 'a' and b values earlier. But when rounding 29.999269 to the nearest hundredth, we get y = 30.

Also, plug x = 4 into the equation to get y = 85.00785875 which rounds to 85.

--------------------------------------------------

The last step is to plug x = 3 into the equation

y = 36.9471*(1.2316)^x

y = 36.9471*(1.2316)^3

y = 69.0222951885528

y = 69.02 which is the final answer

--------------------------------------------------

If you were to use those more accurate values of 'a' and b, then x = 3 would lead to y = 69.0175266335801; that rounds to 69.02 when rounding to the nearest hundredth (aka 2 decimal places). So this shows we can stick with the less accurate 'a' and b values while still getting the correct final answer.

GeoGebra and Desmos are great tools to help quickly verify the answer.

Answer:

f(3) = 69.02  (nearest hundredth)

Step-by-step explanation:

An exponential function is used to calculate the exponential growth or decay of a given set of data.  In an exponential function, the variable is the exponent.

[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]

Given:

Substitute these values into the general form of an exponential function to create two equations in terms of a and b:

[tex]\begin{aligned}\implies f(-1)&=30\\ab^{-1}&=30\end{aligned}[/tex]

[tex]\begin{aligned}\implies f(4)&=85\\ab^{4}&=85\end{aligned}[/tex]

Divide the second equation by the first equation to eliminate a:

[tex]\begin{aligned}\implies \dfrac{ab^4}{ab^{-1}}&=\dfrac{85}{30}\\\\\dfrac{b^4}{b^{-1}}&=\dfrac{85}{30}\\\\\end{aligned}[/tex]

Solve for b:

[tex]\begin{aligned}\implies \dfrac{b^4}{b^{-1}}&=\dfrac{85}{30}\\\\b^{4-(-1)}&=\dfrac{17}{6}\\\\b^{5}&=\dfrac{17}{6}\\\\b&=\sqrt[5]{\dfrac{17}{6}}\end{aligned}[/tex]

Substitute the found value of b into ab⁴ = 85:

[tex]\implies a\left(\sqrt[5]{\dfrac{17}{6}}\right)^4=85[/tex]

Solve for a:

[tex]\implies a=\dfrac{85}{\left(\sqrt[5]{\dfrac{17}{6}}\right)^4}[/tex]

[tex]\implies a=\dfrac{85}{\sqrt[5]{\dfrac{17^4}{6^4}}}[/tex]

[tex]\implies a=\dfrac{85}{\sqrt[5]{\dfrac{83521}{1296}}}[/tex]

Substitute the found values of a and b into the exponential function formula to create an exponential equation for the given parameters:

[tex]f(x)=\left(\dfrac{85}{\sqrt[5]{\dfrac{83521}{1296}}}\right)\cdot \left(\sqrt[5]{\dfrac{17}{6}}\right)^x[/tex]

To find the value of f(3), substitute x = 3 into the equation:

[tex]\begin{aligned}\implies f(3)&=\left(\dfrac{85}{\sqrt[5]{\dfrac{83521}{1296}}}\right)\cdot \left(\sqrt[5]{\dfrac{17}{6}}\right)^3\\\\&=69.0175266...\\\\&=69.02\; \;\sf (nearest\;hundredth)\end{aligned}[/tex]

Therefore, the value of f(3) to the nearest hundredth is 69.02.

Step-by-step explanation:

To find the center and radius of the circle represented by the equation:

x^2 + y^2 - 8x - 20y + 52 = 0

We can start by completing the square for both x and y terms as follows:

(x^2 - 8x) + (y^2 - 20y) + 52 = 0

(x^2 - 8x + 16) + (y^2 - 20y + 100) + 52 = 16 + 100

(x - 4)^2 + (y - 10)^2 = 64

Thus, the equation can be rewritten in the standard form of the circle as:

(x - 4)^2 + (y - 10)^2 = 8^2

Therefore, the center of the circle is (4, 10), and its radius is 8 units.

Step-by-step explanation:

x² + y² - 8x - 20y + 52 = 0

the standard circle equation is

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle, and r is the radius.

now, we need to find the squared terms in the original equation.

x² and y² are clearly from the (x - h)² and (y - k)².

and then

(x - h)² = x² - 2hx + h²

-2hx = -8x

2h = 8

h = 4

(y - k)² = y² - 2ky + k²

-2ky = -20y

2k = 20

k = 10

h² + k² = 16 + 100 = 116

116 - r² = 52

r² = 64

r = 8

so, the center is (4, 10), the radius is 8.

V = πr²h, where V is a cylinder's volume, r is its radius, and h is its height, is the formula for calculating a cylinder's volume. The formula is created by first determining the area of the cylinder's base, which equals r2, and then multiplying that area by the cylinder's height to determine the volume. The volume of tanks, pipelines, and other cylindrical objects may be calculated using this formula, among many other uses.

The volume of a cylinder, which is:

V = πr²h

Given that, diameter is 15 feet, so the radius is 7.5 feet.

A ratio or value stated as a percentage of 100 is referred to as a percentage in mathematics. The abbreviations "pct.," "pct," and "pc" are also sporadically used. Nonetheless, the percentage symbol "%" is frequently used to denote it. The percentage amount is dimensionally empty. When the denominator is 100, percentages are essentially fractions. To show that a number is a percentage, a percent symbol (%) should be used next to it. For instance, you receive a 75% grade if you correctly answer 75 out of 25 questions (75/100) on a test. For percentage calculations, multiply the outcome by 100 after dividing the amount by the total. The percentage is calculated by multiplying (value/total) by 100%.  

You may use the following calculation to get the percentage change between $1,000 and $332.03:

(|new value - old value| / old value|) x 100% represents the percentage change.

In this instance, the new value is $332.03 while the previous value was $1,000.

percentage change = (|332.03 - 1000| / 1000| x 100% = f 66.797%.

The percent error for the 121-foot measurement is approximately 0.83%.

In the event of contrasting a measured or trial value with a known or accepted value, percent error is employed, whereas percent difference is used to compare two values. The percentage difference is determined by dividing the absolute variance of two numbers by their average, then multiplying the result by 100%.

For the 121-foot measurement:

Absolute error = |121 - 120| = 1

Percent error = (absolute error / actual value) x 100%

Percent error = (1 / 120) x 100%

Percent error ≈ 0.83%
