Answer:

x ≈ 11.3

Step-by-step explanation:

using the cosine ratio in the right triangle

cos61° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{DE}{DF}[/tex] = [tex]\frac{5.5}{x}[/tex] ( multiply both sides by x )

x × cos61° = 5.5 ( divide both sides by cos61° )

x = [tex]\frac{5.5}{cos61}[/tex] ≈ 11.3 ( to the nearest tenth )

A reflection transformation on a coordinate plane changes the figure over a line called the line of reflection. This line acts as a reflect and the picture created by the change could be a reflect picture of the first figure.

b. In case a figure is reflected over the x-axis, the x-coordinates of all the focuses within the figure will stay the same, but the y-coordinates will be increased by -1. So, in the event that a point on the initial figure has arranges (x,y), its picture after reflecting over the x-axis will have arranges (x,-y).

c. In case a figure is reflected over the y-axis, the y-coordinates of all the points within the figure will remain the same, but the x-coordinates will be copy by -1. So, in case a point on the first figure has push (x,y), its image   after reflecting over the y-axis will have arranges (-x,y).

Therefore, d. To reflect a triangle over the y-axis, we need to know the  the mirror image  of each point with regard to the y-axis. One way to do usually to increase the x-coordinate of each point by -1 and also keeping the y-coordinate the same.

1) The decay constant is  0.0385

2) The amount after ten years is  27.2 mg

3) The time taken for 10 mg to remain is  36 years.

We know that;

P = Poe^-kt

Given that the half life is 18 years;

20=40e^-18k

20/40=e^-18k

0.5 =e^-18k

ln0.5 = -18k

k = -0.693/-18k

After 10 years we have;

P = 40e^-10(0.0385)

P = 27.2 mg

10 mg will remain when;

Answer:

Step-by-step explanation:

Any quarter with sales level less than or equal to 7.908 million dollars would be considered a "failure" by this company.

To determine this sales level, we need to find the 20th percentile of the normal distribution with mean 9 million dollars and standard deviation 1.3 million dollars.

By using a standard normal distribution table we can find that the z-score corresponding to the 20th percentile is approximately -0.84.

The sales level that is the cutoff between quarters that are considered "failures" will be:

-0.84 = (x - 9)/1.3

- 0.84 * 1.3 = x - 9

- 1.092 = x - 9

x = 9 - 1.092

x = 7.908

A function which has the greater maximum value is: function f(x).

In Mathematically, the axis of symmetry of a quadratic function can be calculated by using this mathematical expression:

Axis of symmetry (vertex), Xmax = -b/2a

Where:

a and b represents the coefficients of the first and second term in the quadratic function.

For the given quadratic function f(x) = -x² - 3x + 1, we have:

Axis of symmetry, Xmax = -(-3)/2(-1)

Axis of symmetry, Xmax = 3/-2 = -1.5.

For the value of k in vertex, we have:

f(x) = -x² - 3x + 1

f(-1.5) = -(1.5)² - 3(-1.5) + 1

f(-1.5) = 3.25

For g(x), the maximum value or vertex is 2 and as such, quadratic function f(x) has the greater maximum value.

There are 264 anagrams of the word CADERNO that have vowels before consonants.

We have,

To count the number of anagrams of the word CADERNO that have vowels before consonants, we can use the following steps:

Count the number of vowels in the word.

In this case, there are three vowels: A, E, and O.

Count the number of consonants in the word.

In this case, there are four consonants: C, D, R, and N.

Determine the possible arrangements of vowels and consonants that satisfy the condition of having vowels before consonants.

Since there are three vowels and four consonants, there are two possible arrangements that satisfy this condition:

a) Vowel - Consonant - Vowel - Consonant - Vowel - Consonant - Consonant

b) Vowel - Consonant - Vowel - Consonant - Consonant - Vowel - Consonant

Calculate the number of ways to arrange the vowels and consonants in each of the possible arrangements determined in step 3.

We can use permutations to calculate this.

For arrangement a):

There are 3 ways to choose the first vowel (A, E, or O)

There are 4 ways to choose the first consonant (C, D, R, or N)

There are 2 ways to choose the second vowel (whichever is left out of the two remaining vowels)

There are 3 ways to choose the second consonant (whichever is left out of the three remaining consonants)

There is 1 way to choose the third vowel (the remaining vowel)

There is 1 way to choose the fourth consonant (the remaining consonant)

There is 1 way to choose the fifth consonant (the remaining consonant)

The total number of arrangements for this case is: 3 x 4 x 2 x 3 x 1 x 1 x 1 = 72

For arrangement b):

There are 3 ways to choose the first vowel

There are 4 ways to choose the first consonant

There are 2 ways to choose the second vowel

There are 2 ways to choose the second consonant (whichever is left out of the two remaining consonants)

There are 2 ways to choose the third consonant (whichever is left out of the two remaining consonants)

There is 1 way to choose the third vowel

There is 1 way to choose the fourth consonant

The total number of arrangements for this case is: 3 x 4 x 2 x 2 x 2 x 1 x 1 = 192

Add up the total number of arrangements for both cases to get the final answer:

72 + 192 = 264

The image of △FGH after the similarity transformation is △F"G"H", with vertices F"(-2, 2), G"(-2, 6), and H"(2, 6).

To perform the similarity transformation, we first apply the translation by subtracting 3 from the x-coordinates and subtracting 1 from the y-coordinates:

F' = (2-3, 2-1) = (-1, 1)

G' = (2-3, 4-1) = (-1, 3)

H' = (4-3, 4-1) = (1, 3)

Next, we apply the dilation with a scale factor of 2 by multiplying each coordinate by 2:

F" = 2(-1, 1) = (-2, 2)

G" = 2(-1, 3) = (-2, 6)

H" = 2(1, 3) = (2, 6)

The measure of the angle is A. 125^o

A measure of an angle which lies between 90^o and 180^0 is said to be obtuse. This implies that the measure of the angle is greater than a right angle but less than the sum of angles on a straight line.

In the given expression, the halfway between 120 and 130 degrees is given as;

(120 + 130)/ 2 = 125

The 90% confidence that the proportion of yellow peas is between 23.5% and 29.5%

and, 25% estimate falls within the 90% confidence limits.

We have,

Green peas= 445

Yellow peas= 161

So, Total peas:

= 445 + 161

= 606.

Now, the Proportion of yellow

= 161/606

= 0.265676

= 26.56%

Now, p= 0. 265 and q= 1-0.265= 0.735

So, np = 606 (0.265)= 160.59

nq = 606(0.735) = 445.41

As, both results are ≥ 5 and the sample can be approximated by a normal distribution.

For 90% confidence, z = 1.645.

Now, the margin error

= 1.645 √ (0.265)(0.735) / 606

Now, The confidence limits are the point estimate ± the margin of error. =

Point of tangency is where the line on the left touches the circle.  Have you ever heard the term "She's going off on a tangent"- it means they only touch the topic(tangent point and go off (tangent line) and talk way off away from where you need to be(circle)

So you can see from the graph the point of tangency (where line touches circle is (-5,0)

the equation for the line is going to be a constant.  The line only touches the x-axis never the y-axis at all points it is x=-5

so the equation of the line x= -5
