Answer:

they are equivalent

Step-by-step explanation:

[tex]\frac{3}{6} = \frac{1}{2} (both \: can \: be \: divide \: by \: 3)[/tex]

[tex] \frac{4}{8} = \frac{1}{2} (both \: can \: be \: divide \: by \: 4)[/tex]

The two (2) fractions are equivalent.

In this exercise, you're required to determine whether or not given fractions are equivalent (equal). In order to do this, we would reduce the fractions to the lowest term.

Given the following fractions;

For Fraction A, we would divide both the numerator and the denominator by 3 because it's common to both them.

Fraction A = [tex]\frac{3}{6} = \frac{1}{2}[/tex]

Simplifying Fraction B, we have;

Fraction B = [tex]\frac{4}{8} = \frac{1}{2}[/tex]

Also, for two (2) fractions to be equivalent, their sums must be equal to one (1).

[tex]Fraction \;A + Fraction \;B = 1[/tex]

[tex]\frac{1}{2} + \frac{1}{2} = 1[/tex]

Therefore, we can deduce from the calculations that the two (2) fractions are equivalent.

The highest point is when y = 0 and the lowest point is when y = -5

We can see this if we draw horizontal lines through the highest and lowest points (see the diagram below). Note where the horizontal lines cross the y axis. For y = 0, we don't really need a horizontal line but I'll draw it anyway.

Since y ranges from y = -5 to y =0, the range is therefore [tex]-5 \le y \le 0[/tex]

Side note: to write this in interval notation, you would say [tex][-5, 0][/tex]. The square brackets say to include each endpoint as part of the range.

Step-by-step explanation:

Given 2 chords intersecting inside a circle, then

the product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is

12(4x + 1) = 14(3 + 3x) ← distribute parenthesis on both sides

48x + 12 = 42 + 42x ( subtract 42x from both sides )

6x + 12 = 42 ( subtract12 from both sides )

6x = 30 ( divide both sides by 6 )

Answer:

The 7th roots are : [tex]$ 1, \frac{2 \pi}{7}, \frac{4 \pi}{7}, \frac{6 \pi}{7}, \frac{8 \pi}{7}, \frac{10 \pi}{7}, \frac{12 \pi}{7}$[/tex]

Step-by-step explanation:

The roots of unity are evenly spread around the unit circle.      

The roots of unity can be find by using the relation

[tex]$ 1= 1 ( \cos 0 ^\circ +i \sin ^\circ )$[/tex]

[tex]$\sqrt[n]{1} = 1 [\cos (\frac{2k \pi}{n}})+ i \sin (\frac{2k \pi}{n}) ] $[/tex]

Now z be a polynomial.

[tex]$z^7=1 \Rightarrow z = 1^{\frac{1}{7}}$[/tex]

therefore, cos 0 = 1.

[tex]$ z = \cos (2k \pi)^{\frac{1}{7}}$[/tex]                [tex]$ (\cos \theta)^n = \cos n \theta $[/tex]

[tex]$ z = \cos \frac{2k \pi}{7} $[/tex]

Now, for k=0, z = 1

[tex]$ k=1 \Rightarrow z = \cos \frac{2 \pi}{7} = \cos 3 \frac{2 \pi}{7}+ i \sin \frac{2 \pi}{7}$[/tex]

[tex]$ k=2 \Rightarrow z = \cos \frac{4 \pi}{7} = \cos \frac{4 \pi}{7}+ i \sin \frac{4 \pi}{7}$[/tex]

[tex]$ k=3 \Rightarrow z = \cos \frac{6 \pi}{7} = \cos \frac{6 \pi}{7}+ i \sin \frac{6 \pi}{7}$[/tex]

[tex]$ k=4 \Rightarrow z = \cos \frac{8 \pi}{7} = \cos \frac{8 \pi}{7}+ i \sin \frac{8 \pi}{7}$[/tex]

[tex]$ k=5 \Rightarrow z = \cos \frac{10 \pi}{7} = \cos \frac{10 \pi}{7}+ i \sin \frac{10 \pi}{7}$[/tex]

[tex]$ k=6 \Rightarrow z = \cos \frac{12 \pi}{7} = \cos \frac{12 \pi}{7}+ i \sin \frac{12 \pi}{7}$[/tex]

[tex]$ k=7 \Rightarrow z = \cos \frac{14 \pi}{7} = \cos \frac{14 \pi}{7}+ i \sin \frac{14 \pi}{7}$[/tex]

Then the 7th roots are : [tex]$ 1, \frac{2 \pi}{7}, \frac{4 \pi}{7}, \frac{6 \pi}{7}, \frac{8 \pi}{7}, \frac{10 \pi}{7}, \frac{12 \pi}{7}$[/tex]

Answer:

y = -3x + 13

Step-by-step explanation:

For slope-intercept form, you need the slope and the y-intercept.  To find the slope, you need to rearrange the given equation to slope-intercept form.

x - 3y = 9

-3y = -x + 9

y = 1/3x - 3

The slope for the given equation is 1/3.  The slope of a perpendicular line will be the negative reciprocal.  This means that the slope of the perpendicular line will be -3.

You can now solve for the y-intercept (b) using the slope (m) and the given point in slope-intercept form.

y = mx + b

1 = (-3)(4) + b

1 = -12 + b

13 = b

b = 13

Now that you have both the slope and y-intercept, you can find the equation.

y = -3x + 13

The equation of the line is y = -3x + 13

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

The slope intercept form is given by:

y = mx + b

m = slope and b = y-intercept

We have,

A line perpendicular to line x - 3y = 9 and the line passes through the point (4, 1).

Make the line x - 3y = 9 in slope-intercept form.

-3y = 9 - x

y = (9 - x) / -3

y = (1/3)x - 3

The slope of the line x - 3y = 9 is:

m1=  1/3

Since the line required to find is perpendicular to the line x - 3y = 9

Let the required line slope be m2

m1 x m2 = -1

m2 = -1 / (1/3) = -3

The required line passes through the point (4, 1).

Let the required line be y = mx + b

we have,

1 = (-3)4 + b

1 = -12 + b

b = 13

We can write as:

y = -3x + 13

Thus the equation of the line is y = -3x + 13

Answer:

Step-by-step explanation:

Answer: The number of dimes is:

Dimes = -(Nickels + Pennies) + 24.

Such that Nickels + Pennies < 24, and each quantity refers to the initial number of coins of the given type.

Step-by-step explanation:

Let's call N = number of nickels, D =  number of dimes, and  P = number of pennies.

The total number of coins is N + D + P

We know that the total value in nickels is:

N*$0.05

The total value in dimes is:

D*$0.10

And the total value on Pennies is:

P*$0.01

Then, the "mean" value of the coins will be equal to the total value of all the coins, divided the total number of coins.

$0.07 = (N*$0.05 + D*$0.10 + P*$0.01)/(N + D + P)

we can mutiply at both sides by the total number of coins, and we have:

$0.07*(N + D + P) = N*$0.05 + D*$0.10 + P*$0.01

Now, if we remove one nickel by five penies, we have:

$0.06 = ((N-1)*$0.05 + D*$0.10 + (P+5)*$0.01)/(N - 1 + D + P + 5)

Again, we multiply in both sides by the total number of coins and:

$0.06*(N - 1 + D + P + 5) = ((N-1)*$0.05 + D*$0.10 + (P+5)*$0.01)

Ok, now we have two equations:

$0.07*(N + D + P) = N*$0.05 + D*$0.10 + P*$0.01

$0.06*(N + D + P + 4) = ((N-1)*$0.05 + D*$0.10 + (P+5)*$0.01)

We can take the second equation and write the right side as:

$0.06*(N + D + P + 4) = ((N-1)*$0.05 + D*$0.10 + (P+5)*$0.01)

                                    = N*$0.05 + D*$0.10 + P*$0.01 - 1*$0.05 + 5*$0.01

                                    =  N*$0.05 + D*$0.10 + P*$0.01

Now, the two equations are:

$0.07*(N + D + P) = N*$0.05 + D*$0.10 + P*$0.01

$0.06*(N + D + P + 4) = N*$0.05 + D*$0.10 + P*$0.01

Then we have that:

$0.07*(N + D + P) = $0.06*(N + D + P + 4)

D*($0.07 - $0.06) = ($0.06 - $0.07)*(N + P)) + 4*$0.06

D*$0.01 = -$0.01(N + P) + 4*$0.06

D = (-$0.01(D + P) + 4*$0.06)/$0.01 = -(N + P) + 24

So the number of Dimes is related to the number of pennies and nickels that we have at the begginig.

Such that in both cases the number of dimes is equal:

D = -(N + P) + 24

Notice that N + P can not be larger or equal than 24, so we have the rule:

N + P < 24.

Answer:

The number of pennies are 91 pennies

Step-by-step explanation:

The given parameters are

When we split the pennies in twos the number left = 1

When the pennies are split in 3s the number left = 1

When the pennies are split in 5s the number left = 1

When the pennies are split in 7 the number left = 0

Therefore, 7 is a factor of the number

Given that when the pennies are split in 5s the number left = 1, the number ends with a 1

We have the products of 7 ending with 1 from Excel as 21 and 91, 161...

We check 91 given 21 is directly divisible by 3 as follows;

91/2 = 45 remainder 1

91/3 = 30 remainder 1

91/5 = 18 remainder 1

91/7 = 13 remainder 0

Therefore, the number of pennies are 91 pennies.

Here is Triangle A. Lin created a scaled copy of Triangle A with an area of 72 square units. What scale factor did Lin apply to the Triangle A to create the copy? Remember: A=1/2bh

a) 4

b) 8

c) 16

Answer:

Scale factor = 16

Step-by-step explanation:

From the diagram attached to this solution, the triangle was plotted on a graph sheet, and each grid on the graph represents 1 unit. hence the dimensions of Triangle A from the diagram is as follows:

Base = 3 units

Height = 3 units

Next, in order to determine the scale factor of the area of the triangle after scaling, let us calculate the area of the unscaled triangle.

Area of Triangle = 1/2 (base × height)

Area or Triangle = 0.5 × 3 × 3 = 4.5 square units

Therefore,

Area of unscaled triangle = 4.5 squared units

Area of scaled triangle = 72 squared units

since the area of the scaled triangle is larger than the unscaled triangle, the scale factor is simply the number of times by which the scaled triangle was enlarged, compared to the unscaled triangle. This can be calculated by dividing the scaled triangle by the unscaled triangle as follows:

Scale factor =(scaled triangle) ÷ (unscaled triangle)

Scale factor =  72 ÷ 4.5 = 16

Answer: 1/4

Step-by-step explanation: In algebra, we use the word slope to describe how steep a line is and slope can be found using the ratio rise/run between any two points that are on that line.

So for the line you see here, let's use these two points to find its slope.

Let's go from left to right.

To get from the point that has the coordinates (0,1) to (4,2),

we rise 1 unit and run 4 units to the right and we end up the other point.

So the slope of this line is 1/4.

Answer:

The probability that a jar contains more than 466 g is 0.119.

Step-by-step explanation:

We are given that a jar of peanut butter contains a mean of 454 g with a standard deviation of 10.2 g.

Let X = Amount of peanut butter in a jar

The z-score probability distribution for the normal distribution is given by;

                                Z  =  [tex]\frac{X-\mu}{\sigma}[/tex]  ~ N(0,1)

where, [tex]\mu[/tex] = population mean = 454 g

           [tex]\sigma[/tex] = standard deviation = 10.2 g

So, X ~ Normal([tex]\mu=454 , \sigma^{2} = 10.2^{2}[/tex])

Now, the probability that a jar contains more than 466 g is given by = P(X > 466 g)

            P(X > 466 g) = P( [tex]\frac{X-\mu}{\sigma}[/tex] > [tex]\frac{466-454}{10.2}[/tex] ) = P(Z > 1.18) = 1 - P(Z [tex]\leq[/tex] 1.18)

                                                                  = 1 - 0.881 = 0.119

The above probability is calculated by looking at the value of x = 1.18 in the z table which has an area of 0.881.
