Answer:

40% decrease

Step-by-step explanation:

10% = 1

(multiply by 6)

60% = 6

100% - 60% = 40%

The final price of the sneaker to the nearest dollar, $69.60 is rounded up to $70. Option C) $70

The final price of the sneaker after a chain discount of 40% less 20% can be calculated as follows:

First, find the discount amount of 40% of $145.00:

40% of $145.00 = 0.40 x $145.00 = $58.00

Then, subtract the 20% discount from the discounted price:

$145.00 - $58.00 = $87.00 (after 40% discount)

$87.00 - 0.20($87.00) = $69.60 (after 20% discount)

The chain offers a 40% discount on the original price of the sneaker. This brings the price down to $87.00. Then, a further discount of 20% is applied on the discounted price of $87.00.

This brings the final price down to $69.60. Since we need to round the final price to the nearest dollar, $69.60 is rounded up to $70.

The statements that must be true about the figure are

AB is bisected by EF,CD is bisected by AB, AE = 1/2 AB, EF = 1/2 ED,

FD = EB.

AB is bisected by EF: This statement is true because point E is the midpoint of AB, meaning it divides AB into two equal parts, and EF is a line connecting the midpoints of the sides. Therefore, EF bisects AB.

CD is bisected by AB: This statement is also true because point F is the midpoint of CD, meaning it divides CD into two equal parts, and AB is a line connecting the midpoints of the sides. Therefore, AB bisects CD.

AE = 1/2 AB: This statement is true because E is the midpoint of AB, which means AE and EB are equal in length. Since E is the midpoint, AE is half the length of AB.

EF = 1/2 ED: This statement is true because F is the midpoint of CD, and EF is a line connecting the midpoints of the sides. Therefore, EF is half the length of CD, and ED is twice the length of EF.

When the shape in the diagram rotates about the dashed line, shape 3, which is a cone with a cylindrical neck, forms a vertical section of a funnel. The correct answer is (C) Shape 3.

If the shape in the diagram rotates about the dashed line, the solid of the revolution formed will be a vertical section of a funnel, which corresponds to shape 3.

Shape 1 is a flat-top cone, which means it has a pointed top and a flat circular base. Rotating it about the dashed line would result in a solid with a pointed top and a flat circular base, resembling a cone. This does not match the description of a funnel, so shape 1 is not the correct answer.

Shape 2 is described as a 3D hexagon with a cylindrical hexagon on its top. Rotating it about the dashed line would not create a funnel shape but a more complex structure, which does not match the given description.

Shape 3 is a cone-shaped body with a cylindrical neck. When this shape is rotated about the dashed line, it will create a solid with a funnel-like shape, with a pointed top and a wider base. This matches the description provided, making shape 3 the correct answer.

Shape 4 is described as a 3D circle with a cylinder on top. Rotating it about the dashed line would not create a funnel shape, but rather a cylindrical shape with a circular base. In conclusion, the correct answer is C. Shape 3.

The correct answer is D. f(x) = 11x - 4 and g(x) = (x + 4)/11

To determine which pair of functions are inverses of each other, we need to check if the composition of the functions results in the identity function, which is f(g(x)) = x and g(f(x)) = x.

Let's test each option:

Option A:

f(x) = x/2 + 15

g(x) = 12x - 15

f(g(x)) = (12x - 15)/2 + 15 = 6x - 7.5 + 15 = 6x + 7.5 ≠ x

g(f(x)) = 12(x/2 + 15) - 15 = 6x + 180 - 15 = 6x + 165 ≠ x

Option B:

f(x) = ∛3x

g(x) = (x/3)^3 = x^3/27

f(g(x)) = ∛3(x^3/27) = ∛(x^3/9) = x/∛9 ≠ x

g(f(x)) = (∛3x/3)^3 = (x/3)^3 = x^3/27 = x/27 ≠ x

Option C:

f(x) = 3/x - 10

g(x) = (x + 10)/3

f(g(x)) = 3/((x + 10)/3) - 10 = 9/(x + 10) - 10 = 9/(x + 10) - 10(x + 10)/(x + 10) = (9 - 10(x + 10))/(x + 10) ≠ x

g(f(x)) = (3/x - 10 + 10)/3 = 3/x ≠ x

Option D:

f(x) = 11x - 4

g(x) = (x + 4)/11

f(g(x)) = 11((x + 4)/11) - 4 = x + 4 - 4 = x ≠ x

g(f(x)) = ((11x - 4) + 4)/11 = 11x/11 = x

Based on the calculations, only Option D, where f(x) = 11x - 4 and g(x) = (x + 4)/11, satisfies the condition for being inverses of each other. Therefore, the correct answer is:

D. f(x) = 11x - 4 and g(x) = (x + 4)/11

The infinite geometric series 1 - 1/5 + 1/25 - 1/125 + ... is convergent and the sum of this infinite geometric series is 5/6.

To determine whether the infinite geometric series is convergent or divergent, and to find its sum if convergent, we'll consider the given series: 1 - 1/5 + 1/25 - 1/125 + ...

Step 1: Identify the common ratio (r).
In a geometric series, each term is a constant multiple of the previous term.

In this case, we can see that the common ratio is -1/5 because each term is obtained by multiplying the previous term by -1/5.

Step 2: Determine convergence or divergence.
An infinite geometric series converges if the absolute value of the common ratio (|r|) is less than 1, and diverges if |r| is greater than or equal to 1.

Since |-1/5| = 1/5 < 1, the series is convergent.

Step 3: Calculate the sum.
For a convergent geometric series, the sum can be found using the formula:
Sum = a / (1 - r)
where 'a' is the first term and 'r' is the common ratio.

In this case, a = 1 and r = -1/5, so:

Sum = 1 / (1 - (-1/5))
Sum = 1 / (1 + 1/5)
Sum = 1 / (6/5)
Sum = 5/6

Therefore, the sum of the infinite geometric series 1 - 1/5 + 1/25 - 1/125 + ... is 5/6.

Find the perpendicular bisectors of the triangle's sides.

For each side of the triangle, construct a line that is perpendicular to the side and passes through its midpoint.

Locate the point of intersection of the perpendicular bisectors.

The point where all three perpendicular bisectors intersect is the center of the circumscribed circle.

Measure the distance from the center to any of the triangle's vertices.

This distance is the radius of the circumscribed circle.

Step-by-step explanation:

By using unitary method, we found that the cost of 5m cloth is Rs. 1050.

According to the unitary method, the cost of 1 meter of cloth is equal to the total cost of 7 meters of cloth divided by 7. That is,

Cost of 1m cloth = Total cost of 7m cloth/7

We know that the total cost of 7m cloth is Rs. 1470. Therefore,

Cost of 1m cloth = 1470/7

Cost of 1m cloth = Rs. 210

This means that the cost of 1 meter of cloth is Rs. 210. Now, we need to find the cost of 5m cloth. To do that, we can use the unitary method again.

Cost of 5m cloth = Cost of 1m cloth x 5

Cost of 5m cloth = Rs. 210 x 5

Cost of 5m cloth = Rs. 1050

Therefore, the cost of 5m cloth is Rs. 1050.

the height of the antenna is approximately 24 meters.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

From the diagram, we see that we need to find the distance d and the height h. We can use the tangent function to find these values.

First, let's find d:

tan(θ) = h / (d + 1.51)

Rearranging, we get:

d = (h / tan(θ)) - 1.51

Next, let's find h:

tan(θ') = h / d

Substituting the expression for d that we found above, we get:

tan(θ') = h / ((h / tan(θ)) - 1.51)

Multiplying both sides by (h/tan(θ1)) - 1.51 and simplifying, we get:

h = (29 * tan(θ') * tan(θ)) / (tan(θ') - tan(θ))

Now we can plug in the values for the angles and solve for h:

h = (29 * tan(31°) * tan(17°)) / (tan(31°) - tan(17°))

h ≈ 24

So the height of the antenna is approximately 24 meters.

Answer: no it does matter because it just the same numbers repeating

Step-by-step explanation:

the polar equation of the form r = f(t) for the curve represented by the Cartesian equation x = 3.sec(t)

To find a polar equation for the given Cartesian equation x = 3, we need to convert it into polar form. We know that x = rcos(t) and substituting x = 3, we get 3 = rcos(t). Solving for r, we get r = 3/cos(t) which simplifies to r = 3sec(t). The polar coordinate system uses an angle t (or theta) and a distance r to describe a point in the plane. To convert a Cartesian equation to polar form, we need to express x and y in terms of r and t. In this case, we are given x = 3. We know that x = rcos(t), so we substitute x = 3 into this equation and get 3 = rcos(t). Solving for r, we get r = 3/cos(t). This can be simplified to r = 3sec(t), which is our polar equation of the form r = f(t).

In this equation, sec(t) is the reciprocal of cos(t), which means that the value of r will get larger as cos(t) gets smaller (i.e. as t approaches 90 degrees or pi/2 radians). This makes sense since the Cartesian equation x = 3 represents a vertical line passing through the point (3,0) on the x-axis. As we move up the line (in the positive y direction), the distance from the origin increases and the angle t approaches 90 degrees. Therefore, the value of r should get larger as t approaches 90 degrees, which is exactly what our polar equation shows.

x = 4 would be the solution of the given problem.

I can't speak to the first part of this question, as I don't totally have context for what they're asking, but we can solve for x using one of the laws of logarithms, namely:

log.m + log.n = log.mn

Using this law, we can combine and rewrite our initial equation as

log(x^2- x) = 3

Remember that logarithms are simply another way of writing exponents. The logarithm  is just another way of writing the fact . Keeping that in mind, we can express our logarithm in terms of exponents as

log(x^2- x) = 3 --> x^2- 2x = 8

2³ = 8, so we can replace the left side of our equation with 8 to get

x^2 - 2x - 8 =0

(x-4)(x+2) = 0
