Recognizing that sin(30º) = 1/2, the exact value of sin(120º) is √3/2.

The exact value of sin(120˚) can be found by using the double angle formula for sine. The formula is:
sin(2θ) = 2sinθcosθ

Since we are given that sin(30˚) = 1/2, we can substitute 30˚ for θ in the formula to find sin(120˚):
sin(120˚) = 2sin30˚cos30˚
sin(120˚) = 2(1/2)(√3/2)
sin(120˚) = √3/2

Therefore, the exact value of sin(120˚) is √3/2.

The rate, in degrees per hour, that the temperature of the compound rose was 5/2

In Kaylee's scientific experiment, she is interested in the rate at which the temperature of a compound is rising. To answer this question, we need to use mathematics to determine the rate, in degrees per hour, that the temperature of the compound rose.

Using the information provided, we can set up a proportion to solve this problem.

We can represent the rate of temperature rise during a certain time period as a/b, where a is the temperature rise and b is the time period.

We can then set this equal to the rate of temperature rise per hour, c/1. Therefore, we have a/b = c/1.

We are told that the temperature rose 1 1/2 every 3/5 of an hour, so a = 1 1/2 and b = 3/5.

Therefore, we can solve for c to get c = 5/2.

The measure of angle F is 61.4° to the nearest degree  and it can be found through Law of Sines.

The law of sines is a mathematical relationship between the lengths of the sides and the angles of a triangle. It states that the ratio of the length of a side of a triangle to the sine of its opposite angle is constant, regardless of the size or shape of the triangle. Using the law of sines, it is possible to calculate the length of any side of a triangle given the lengths of the other two sides and the measure of their included angle, or to calculate the measure of any angle given the lengths of the three sides. The law of sines can also be used to solve oblique triangles, which are triangles that are not right triangles.

The measure of angle F can be found using the Law of Sines, which states that:

a/sinA = b/sinB = c/sinC

Where a, b, and c are the sides of the triangle and A, B, and C are the angles opposite those sides.

In this case, a = h = 99 cm, b = f = 55 cm, and c = unknown. We are given the measure of ∠H = 169° and we are trying to find ∠F.

Rearrange the equation to solve for ∠F:

sinF = (a/c) * sinH

sinF = (99/c) * sin169

Now, let's solve for c:

c = (99/sin169) * sinF

Solve for sinF:

sinF = (99/c) * sin169

Solve for sinF. Plugging in the values we have (99/c) and sin169, we get sinF = 0.835.

To find the measure of angle F:

∠F = arcsin(0.835)

∠F ≈ 61.4°

Therefore, the measure of angle F is 61.4° to the nearest degree.

The total amount of space taken up on the sign by the letters in Hannah's name is between 3 and 4 whole numbers.

If each letter takes up 5/8 inch of space, then the total amount of space taken up by all 6 letters in Hannah's name is:

6 letters × 5/8 inch per letter = 30/8 inches = 3 6/8 inches = 3 3/4 inches

To find the range of whole numbers between which 3 3/4 inches falls, we can convert 3 3/4 to an improper fraction:

3 3/4 = (4 × 3 + 3)/4 = 15/4

Now we can find the two whole numbers that 15/4 is between by dividing 15 by 4:

15 ÷ 4 = 3 with a remainder of 3

So 15/4 is between 3 and 4, specifically:

3 < 15/4 < 4

Therefore, the total amount of space taken up on the sign by the letters in Hannah's name is between 3 and 4 whole numbers.

The solution of the given problem of surface area comes out to be Tara and Veronica will need about 15.26 bottles of paint to cover the banner.

Its surface area is a reliable indicator of its overall size. When figuring out the right triangle squared, the environment is taken into account. The surface area of everything determines its overall size. The total of the volumes from each of the twelve vertical sides makes up the water volume inside a cuboid. Utilize the following formula to get the box's dimensions: The region is represented by 2lh, 2lw, & 2hW. (SA). The area is represented by the flexible shape's entire surface area.

Here,

To calculate the number of paint bottles needed, we need to first find the area of the parallelogram-shaped banner.

Area = base × height

The apothem is given as 9.52 cm, which is also the height of one of the triangles. The base of each of these triangles is half of the length of the banner, which is 6.8/2 = 3.4 cm. Using the Pythagorean theorem, we can solve for the height "h" of each triangle:

h² = (9.52)² - (3.4)²

h ≈ 8.56 cm

So the total height of the parallelogram is twice this value, or approximately 17.12 cm. Therefore, the area of the banner is:

Area = b × 17.12

864 × 2.54² ≈ 5574.14 cm²

So the area of the banner is:

Area = b × 17.12 = 2(6.8 + b) × 8.56 - 5574.14

Simplifying this expression, we get:

Area = 17.12b - 226.67

Now we can solve for "b" by setting this expression equal to the area of the banner that can be painted:

16(24) = 384 square feet = 384 × 144 ≈ 55302.74 cm²

17.12b - 226.67 = 55302.74

17.12b = 55402.41

b ≈ 3232.87 cm

Finally, we can calculate the area of the painted portion of the banner:

Area painted = (6.8 + b) × 17.12 - 6

Area painted ≈ 5826.24 cm²

To find the number of paint bottles needed, we divide the area painted by the coverage of one bottle:

Number of bottles = Area painted / (16 × 24)

Number of bottles ≈ 15.26

So Tara and Veronica will need about 15.26 bottles of paint to cover the banner.

We can estimate that approximately 35 gas stations sell a gallon of regular gas for no more than $2.01.

What is the percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%". The percentage can be calculated by dividing the value by the total value and then multiplying the result by 100.

a) To find the percentage of gas stations that sell regular gas for less than $1.973, we need to calculate the z-score corresponding to this value:

z = (1.973 - 2.05) / 0.47 = -0.164

Using a standard normal distribution table or calculator, we can find that the percentage of gas stations selling regular gas for less than $1.973 is approximately 44.38%.

b) To find the percentage of gas stations selling regular gas for at least $2.17, we can calculate the z-score corresponding to this value:

z = (2.17 - 2.05) / 0.47 = 0.255

Using a standard normal distribution table or calculator, we can find that the percentage of gas stations selling regular gas for at least $2.17 is approximately 40.86%.

c) To find the probability that a gas station sells regular gas for less than $1.97 or greater than $2.05, we can calculate the z-scores for each value:

z1 = (1.97 - 2.05) / 0.47 = -0.164

z2 = (2.05 - 2.05) / 0.47 = 0

Using a standard normal distribution table or calculator, we can find the probabilities corresponding to each z-score:

P(z < -0.164) = 0.4364

P(z > 0) = 0.5 - 0.5(0) = 0.5

To find the probability that a gas station sells regular gas for less than $1.97 or greater than $2.05, we can add these probabilities:

P(z < -0.164 or z > 0) = P(z < -0.164) + P(z > 0) = 0.4364 + 0.5 = 0.9364

Therefore, the probability that a gas station sells regular gas for less than $1.97 or greater than $2.05 is approximately 93.64%.

d) To find the number of gas stations that sell regular gas for no more than $2.01, we can calculate the z-score corresponding to this value:

z = (2.01 - 2.05) / 0.47 = -0.085

Using a standard normal distribution table or calculator, we can find the probability corresponding to this z-score:

P(z < -0.085) = 0.4664

Multiplying this probability by the total number of gas stations (75), we can estimate the number of gas stations that sell regular gas for no more than $2.01:

0.4664 * 75 ≈ 35

Therefore, we can estimate that approximately 35 gas stations sell a gallon of regular gas for no more than $2.01.

Vaina

y = -x^2 - 6x + 16

0 = -x^2 - 6x + 16

x^2 + 6x - 16 = 0

Podemos resolver esta ecuación usando la fórmula cuadrática:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

donde a = 1, b = 6 y c = -16.

x = (-6 ± sqrt(6^2 - 4(1)(-16))) / 2(1)

x = (-6 ± sqrt(100)) / 2

x = (-6 ± 10) / 2

Esto nos da dos soluciones posibles:

x1 = (-6 + 10) / 2 = 2

x2 = (-6 - 10) / 2 = -8

La base del arco se extiende desde x = -8 hasta x = 2, por lo que el ancho del arco en su base es:
