Does an acute angle measure less than 90 degrees?

Answer:

8 quarters and 19 nickels

Step-by-step explanation:

so, 4 quarters = $1.00 so, knowing that, 8 quarters = $2.00

so now we had to find the amount of nickels so, to find that, we had to divide 95 and 5, which ended up being 19 nickels.

and to check ur answers, you can do 25 times 8 plus 19 times 5. and that equals 295.

Answer : The interval of convergence is (-2/9+7, 20/9+7), which simplifies to (61/9, 209/9).

To find the interval of convergence of the given power series, we can use the ratio test. The ratio test states that if lim |(a_n+1)/(a_n)| = L, then the series converges absolutely if L < 1 and diverges if L > 1.

In this case, we have a_n = (x-7)^n / (n*(-9)^n), so a_n+1 = (x-7)^(n+1) / ((n+1)*(-9)^(n+1)). Taking the ratio of a_n+1 and a_n and simplifying, we get:

|(a_n+1)/(a_n)| = |(x-7)*(-9)/((n+1)*n)|

Taking the limit as n approaches infinity, we get:

lim |(a_n+1)/(a_n)| = |(x-7)*(-9)/n^2|

If |(x-7)*(-9)/n^2| < 1, then the series converges absolutely. Solving for x, we get:

|x-7| < 1/9 * sqrt(n^2)

|x-7| < n/9

So the interval of convergence is (-2/9+7, 20/9+7), which simplifies to (61/9, 209/9). Therefore, the power series converges absolutely for all x in this interval.

options B, D, and E are correct. Option A is incorrect because it uses the wrong length measurement.

what is a rectangle?

A rectangle is a four-sided flat shape with straight sides, where opposite sides are parallel and equal in length. It has four right angles (90-degree angles) at each corner. The length and width of a rectangle are its two main dimensions, and the area of a rectangle is calculated by multiplying its length by its width.

Based on the picture, we can see that the glass has a rectangular shape with dimensions of 4 feet and 5 2/12 feet. Therefore, the equations that can be used to find the area, in square feet, of the piece of glass are:

B. A = 5 2/12 + 4 = 9 2/12 = 7/3 square feet

D. A = 5 2/12 × 4 = 20 1/3 square feet

E. A = (2 × 2 1/2) + (2 × 4) = 9 square feet

Therefore, options B, D, and E are correct. Option A is incorrect because it uses the wrong length measurement. Option C is incorrect because it adds the dimensions instead of multiplying them. Option F is also incorrect because it adds the dimensions instead of multiplying.

Options B, D, and E correctly calculate the area of the glass by multiplying the length by the width. Option B adds the length and width before multiplying them, while option D multiplies the length and width directly.

To answer this question, we need to remember that if we have the function f(x), the function -f(x) is the reflection of the function f(x) in the x-axis.

Then, the graph of the function g(x) is the same as g(x) = -f(x). Then, we have that:

Then

We can check this graphically as follows (the red graph is the function f(x) = 4|x| and the blue function is g(x) = -4|x|):

Therefore, g(x) = -4|x| is the reflection of the function f(x) = 4|x| over the x-axis.

Answer: It is the distance that -5 is form 0 on the number line

Step-by-step explanation:

We can define the absolute value of any number:

IxI as:

"The distance between the point x and the origin in the coordinate axis"

If we are in one dimension, x is just a value, and the coordinate axis will be a number line.

Then we could rewrite this as:

"is the distance between the value x and the 0 in the number line"

So:

IxI = x if x > 0

IxI = -x if x < 0.

Then:

I -5 I

Is the distance between the number -5, and the 0 in the number line, and this is:

I - 5 I = 5.

The correct option is:

"It is the distance that -5 is form 0 on the number line"

Since it is a right angled triangle, we'll use the Pythagoras theorem to check If the lenghts are equal.

From the three lenghts given the longer side should be the hypotenus, that is 9, while the other two are the shorter sides. Therefore :

c² = a² + b²

9² = 6² + 8²

81 ≠ 100

Hence it is not a right angle triangle.

The sides of the triangle are;

c = 5√2

b = 3√3

A right triangle is a triangle that has a right angle that measures 90 degrees. The hypotenuse, which is the side that faces the right angle, is the longest side. The right triangle's other two sides are referred to as its legs.

1) Cos 45 = 5/c

√2/2 = 5/c

c√2 = 10

c = 10/√2

c = 5√2

2) Tan 30 = b/3

√3/3 = b/3

3√3= 3b

b = 3√3/3

b = 3√3

well, for the piece-wise function, we know that hmmm x = -1, -1 is less 1, so the subfunction that'd apply to that will be -2x + 1, because on that section "x is less than or equals to 1".

so f(-1) => -2(-1) + 1 => 3.

Answer:3

Two 6-sided dice are rolled 40 times and the data from each roll is recorded to has 3 even and 3 odd numbers.

Probability of getting even number is

3/6 = 0.5

i.e. 50%

Out of 40 rolls there are 50% chances to get even number. i.e.

50 × 1/100 × 40 = 20

Thus 20 is the answer,

It’s true that the outcome of 20 is the most likely outcome, but is it likely? Actually you’ll only get an outcome of exactly 20 about 12.5% of the time.

57% of the time you’ll get an outcome of 18, 19, 20, 21, or 22.

If you want a range that occurs >95 % of the time, you’ll need to cover 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26.

There are 3080 ways 3 men and 2 women can be chosen if they are equally considered, using the multiplication principle of counting

The multiplication principle states that if there are m ways to perform one task and n ways to perform another task, then there are m x n ways to perform both tasks together.

To find the number of ways to choose 3 men from the 12 men, we can use the formula for combination, which is: ⁿCᵣ = n! / (r! (n-r)!).

where n is the total number of men and r is the number of men chosen

so, the number of ways to choose 3 men from the 12 men = ¹²C₃ = 1.

Similarly, we evaluate the number of ways to choose 2 women from the 8 women

as = ⁸C₂ = 14

Now, using the multiplication principle, we can find the total number of ways 3 men and 2 women be chosen if they are equally considered.

The measure of each interior angle of a dodecagon is 150 degrees. It's important to remember that the measure of each interior angle in a regular polygon is the same for all angles.


1. A dodecagon is a polygon with 12 sides.
2. To find the measure of each interior angle, we can use the formula: (n-2) x 180, where n is the number of sides of the polygon.
3. Substituting the value of n as 12 in the formula, we get: (12-2) x 180 = 10 x 180 = 1800 degrees.
4. Since a dodecagon has 12 sides, we divide the total measure of the interior angles (1800 degrees) by the number of sides, giving us: 1800/12 = 150 degrees.
5. Therefore, each interior angle of a dodecagon measures 150 degrees.
