The sales tax is $1.50 Her total cost of the shirt is $31.50

Step-by-step explanation:

5% of 30 is 20% of 100 so divide 30 by 20 to get 1.5 then just add that to 30 pretty simple :)

The length of the rectangle is 11 centimeters, and the width is 36 centimeters.

Let's denote the length of the rectangle as L and the width as W. Given that the length is an integer and the width is 3 times the next consecutive integer, we can write the width as 3(L + 1).

The formula for the perimeter of a rectangle is P = 2L + 2W. Since the perimeter is 94 centimeters, we can write the equation as:

94 = 2L + 2W

Now substitute W with 3(L + 1):

94 = 2L + 2(3(L + 1))

Simplify the equation:

94 = 2L + 6L + 6

Combine like terms:

94 = 8L + 6

Subtract 6 from both sides:

88 = 8L

Divide by 8:

11 = L

Now that we have the length, let's find the width:

W = 3(L + 1) = 3(11 + 1) = 3(12) = 36

So 11 cm is length and 36 cm is the width if the rectangle.

When searching for the value 10 in the array [2, 3, 5, 6, 9, 13, 16, 19], a recursive binary search algorithm will return false since the element is not found in the array.

About Binary Search Algorithm

The binary search algorithm, applied on arrays are of recursive type. The broad strategy is to look at the middle item on the list. The procedure of the binary search algorithm is either terminated (key found), the left half of the list is searched recursively, or the right half of the list is searched recursively, depending on the value of the middle element.

The function carrying out the binary search algorithm in a code returns true if the desired element is found in the array, else returns false. Since the element 10 is not present in the given array: [2, 3, 5, 6, 9, 13, 16, 19], the binary search algorithm will return false.

Answer:

C = 7.72 ~ 7.7

Step-by-step explanation:

So when you solve this equetion you must 1st find x then c

we can find x by using cos(60)

cos(60) = x/14

x = cos(60) × 14

x = 1/2 ×14

x = 7

so after we find x we are going to solve c by using cos (25)

cos (25) = X/C = 7/c

cos(25) × C = 7

C = 7/cos (25)

C = 7.72 ~ 7.7

so the solution is 7.7

By definition, the x-coordinate of the terminal point is equal to cos t and the y-coordinate is equal to sin t. This allows us to easily find the values of sin t and cos t. To find tan t, we use the formula tan t = sin t / cos t, which we can substitute with our previously found values for sin t and cos t.

First need to understand what is meant by the terms "terminal point" and "unit circle". The unit circle is a circle with a radius of 1, centered at the origin of the coordinate plane. The terminal point is the point where the circle intersects with a line that starts at the origin and passes through an angle t measured in radians.
To find sin t and cos t, we need to look at the coordinates of the terminal point. Let's call the x-coordinate of the terminal point x' and the y-coordinate y'. By definition, x' = cos t and y' = sin t. Therefore, sin t = y' and cos t = x'.
To find tan t, we use the formula tan t = sin t / cos t. Substituting in our values for sin t and cos t, we get:
tan t = y' / x'
So, to summarize:
- sin t = y'
- cos t = x'
- tan t = y' / x'
In summary, we can use the unit circle to determine the values of sin t, cos t, and tan t for any angle t measured in radians. The terminal point on the unit circle is the point where the circle intersects with a line passing through the origin at angle t.

Answer:

coordinates of H = (1, 0)

Coordinates of G = ( - 3.6, -2) or (5.6, -2)

Step-by-step explanation:

E(5,3) and F (2,-1) are two vertices of a square EFGH and H is in the x-axis.

Let the coordinates of H is (x, 0) and G is (a, b).

The length of side EF is

\(EF = \sqrt{(5 -2)^2 + (3 +1)^2} = 5\)

So,

\(EH = \sqrt{(5 -x)^2 + (3 -0)^2} = 5\\\\(5 -x)^2+ 9 = 25\\\\5 - x = 4\\\\x = 1\)

And

\(GH = \sqrt{(a -x)^2+ b^2} = 5\\\\(a -1)^2+ b^2 = 25\\\\a^2 + b^2 + 1 - 2 a = 25\\\\a^2 + b^2 - 2a = 24 .... (1)\)

Now

\(FG = \sqrt{(a -2)^2+ (b +1)^2} = 5\\\\(a -2)^2+ (b+1)^2 = 25\\\\a^2 + b^2 + 2b - 2 a = 20\\ ..... (2)\)

Solving (1) and (2)

b = - 2 ,

\(a = \frac{2 \pm\sqrt{4 + 80}}{2}\\\\a = \frac{2 \pm 9.2}{2}\\\\a = - 3.6, 5.6\)

2 spinners with 5 sectors numbered 1 to 5 gives 25 possible outputs.

Spinner 1 + Spinner 2

1 + 1

If you use the same pattern to find all 25 outputs, then the results show 3 possibilities of a total less than 9 when you spin both these spinners.

The pine trees will be of equal height after 3 years.

Let x be the number of years required for the trees to be of equal height. Then, the height of the tree of variety A is given by H = 15 + 10x. Similarly, the height of the tree of variety B is given by H = 4 + 20x.

To find the value of x, we can equate these two equations as shown below: 15 + 10x = 4 + 20x11 = 10x x = 11/10. Thus, it will take 11/10 years for the trees to be of equal height. Converting this into months gives 11/10 × 12 = 13.2 months. Therefore, it will take about 13.2 months or 3 years for the trees to be of equal height.

The missing length of the triangle using Pythagoras theorem is; x = 3

Pythagoras Theorem is defined as the way in which you can find the missing length of a right angled triangle. The right angle triangle has three sides, the hypotenuse (which is always the longest), Opposite (which doesn't touch the hypotenuse) and the adjacent (which is between the opposite and the hypotenuse).

The formula to find the sides is;

hypotenuse² = opposite + adjacent²

We are given;

Hypotenuse = 5

Opposite = x

adjacent = 4

Thus;

5² = x² + 4²

x² = 5² - 4²

x² = 25 - 16

x = √9

x = 3

We conclude that it is the missing length of the triangle

The rate of fetal growth (dH/dt) is equal to -0.23961 divided by the age in weeks

(a) To calculate the rate of fetal growth with respect to time, we need to differentiate the formula for head circumference (H) with respect to age (t).

dH/dt = 1.07312 * (-0.22331) * (1/t) = -0.23961/t

Therefore, the rate of fetal growth (dH/dt) is equal to -0.23961 divided by the age in weeks (t).

(b) To compare the rate of fetal growth at different ages, let's evaluate dH/dt at t = 8 weeks and t = 36 weeks.

At t = 8 weeks:

dH/dt = -0.23961/8 ≈ -0.029951

At t = 36 weeks:

dH/dt = -0.23961/36 ≈ -0.006655

Comparing the values, we can see that the rate of fetal growth at t = 8 weeks (approximately -0.029951) is larger in magnitude compared to the rate of fetal growth at t = 36 weeks (approximately -0.006655). Therefore, the fetus grows faster early in development (at t = 8 weeks) compared to later stages (at t = 36 weeks).

(c) To calculate the fractional rate of growth (Hdt), we need to multiply the rate of fetal growth (dH/dt) by the head circumference (H)

Hdt = H * dH/dt

Substituting the formula for H into the equation:

Hdt = (-29.53 + 1.07312 - 0.22331log(t)) * (-0.23961/t)

To compare the fractional rate of growth at different ages, we can evaluate Hdt at t = 8 weeks and t = 36 weeks.

At t = 8 weeks:

Hdt ≈ (-29.53 + 1.07312 - 0.22331log(8)) * (-0.23961/8)

At t = 36 weeks:

Hdt ≈ (-29.53 + 1.07312 - 0.22331log(36)) * (-0.23961/36)

By comparing the values, we can determine which age has a larger fractional rate of growth (Hdt).

The correct set of possible results would be (0, 1, 0, 0), (1, 2, 1, 0) and (1, 2, 0, 1).

Your approach seems to be correct, but there seems to be a minor mistake in your final list of possible solutions. Let's go through the steps to clarify.

Given the initial conditions z=t=0, you obtained a partial solution (0,1,0,0).

Next, you solved the homogeneous equations for z=1 and t=0, which resulted in a solution (1,1,1,0).

Similarly, solving the homogeneous equations for z=0 and t=1 gives another solution (1,1,0,1).

To find the general solution, you combine the partial solution with the solutions obtained in the previous step, using parameters a and b.

(0,1,0,0) + a(1,1,1,0) + b(1,1,0,1)

Expanding this expression, you get:

(0+a+b, 1+a+b, 0+a, 0+b)

Simplifying, you obtain the following set of solutions:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Therefore, the correct set of possible results would be:

The median distance driven by the company's bus drivers in the past week is 261.5 miles.

To find the median of the given sample data, we first need to arrange the data in order from smallest to largest:

45, 70, 242, 255, 268, 268, 452, 490

The median is the middle value in the data set. If the data set has an odd number of values, then the median is the middle value. If the data set has an even number of values, then the median is the average of the two middle values.

In this case, we have 8 values, which is an even number. The two middle values are 255 and 268. To find the median, we take the average of these two values:

median = (255 + 268) / 2

= 523 / 2

= 261.5

Therefore, the median distance driven by the company's bus drivers in the past week is 261.5 miles.

To prove the statement P(n) that n cents of postage can be formed with just 4-cent and 11-cent stamps using strong induction where n ≥ 30:

We need to first identify the proper basis step used in strong induction.
Step 1:  Basis step
We need to show that P(n) is true for the initial values of n.

Since n ≥ 30, we will check for n = 30, 31, 32, and 33.
For n = 30: 3 * 4-cent stamps + 2 * 11-cent stamps = 12 + 22 = 30 cents
For n = 31: 1 * 4-cent stamps + 3 * 11-cent stamps = 4 + 33 = 31 cents
For n = 32: 8 * 4-cent stamps = 32 cents
For n = 33: 5 * 4-cent stamps + 2 * 11-cent stamps = 20 + 22 = 33 cents
Since P(n) is true for n = 30, 31, 32, and 33, the basis step is complete.

The equation of the straight line that has x-intercept 1 and y-intercept 4 is:

4x - y = 4

"A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point."

Given, the line has a x-intercept of 1 and y-intercept of 4. T

Therefore, the line passes through the points (1, 0) and (0, 4).

Now, we can find the slope of the line 'm' that passes through those either points.

Therefore, (x₁ - x₂) = m(y₁ - y₂)

⇒ (1 - 0) = m(0 - 4)

⇒ m = \(\frac{1}{4}\)

Now, the equation of the line that has x-intercept 1 and y-intercept 4 is:

(x - x₁) = m(y - y₁)
