Find the value of and round to the nearest hundredth.
8 cm
13 cm
8°
Answer:
37.98°
Step-by-step explanation:
You want the value of θ in a right triangle with a hypotenuse of 13 cm and a side opposite the angle of 8 cm.
SineThe sine relation is ...
Sin = Opposite/Hypotenuse
In this figure, that means ...
sin(θ°) = (8 cm)/(13 cm)
The value of θ is found using the arcsin function:
θ° = arcsin(8/13) ≈ 37.98°
__
Additional comment
You will note the calculator mode is set to DEGrees.
The inverse function of the sine function is called the "arcsine" function. It is represented on most calculator keypads using a -1 exponent. (-1 is usually used with a function name to signify the inverse function. Here, the inverse sine function gives "the angle whose sine is ...".)
Typical units used for angles are degrees, radians, and gradians. The number that is the argument of the inverse sine function is a "pure number" with no units. If you find your calculation causes it to have units, then you need to check your work. (Here the units of cm in numerator and denominator cancel, leaving the unitless value 8/13.)

Answer:
17/50
Step-by-step explanation:
When the bus is on time 4/5 of the time, it is late 1/5 of the time.
Mason arrives at 9 am when the bus is on time 3/4 of the time, so he doesn't arrive at 9 am 1/4 of the time.
Mason arrives at 9 am when the bus is late 3/10 of the time, so he doesn't arrive at 9 am 7/10 of the time.
The probability for Mason not to arrive at 9 am when the bus is on time is:
4/5 × 1/4 = 1/5
The probability for Mason not to arrive at 9 am when the bus is late is:
1/5 × 7/10 = 7/50
The probability for Mason not to arrive at work by 9 am is:
1/5 + 7/50 = 17/50.
Given the polynomial f(x)=3x3-4x2-3x-1, what is the smallest positive integer a such that the intermediate value theorem guarantees a zero exist between zero and a
The smallest positive integer a that satisfies the conditions of the problem is a = 2.
The Intermediate Value Theorem states that if a function f(x) is continuous on the interval [a, b] and takes on values f(a) and f(b) at the endpoints a and b, respectively, then for any value c between f(a) and f(b), there exists at least one value x in the interval [a, b] such that f(x) = c.
In this problem, we are asked to find the smallest positive integer a such that the Intermediate Value Theorem guarantees a zero exists between 0 and a for the polynomial f(x) = 3x³ - 4x² - 3x - 1.
To find this value of a, we need to evaluate f(0) and f(a) and look for a value of a such that f(0) and f(a) have opposite signs. This will guarantee the existence of a root of f(x) between 0 and a.
Evaluating f(0), we get:
f(0) = 3(0)³ - 4(0)² - 3(0) - 1 = -1
To find f(a), we need to solve for a using the equation f(a) = 0. We can use a numerical method, such as the Newton-Raphson method or the bisection method, to find the root of f(x) = 0. Using a calculator or a computer program, we find that f(a) = 0 for a ≈ 1.353.
Since f(0) = -1 and f(a) = 0 have opposite signs, the Intermediate Value Theorem guarantees the existence of at least one zero of f(x) between 0 and a = 1.353. Therefore, the smallest positive integer a that satisfies the conditions of the problem is a = 2.

How to calculate the relative frequencyIn order to ascertain the relative frequency of "tails" when the friends amalgamate their outcomes, one must accumulate the amount of tails, then divide that sum by the entirety of trials:
Relative frequency of "tails" = total number of tails / cumulative number of trials
= 129 / (117 + 129)

3. Use the relationship between 21 and 25 to decide whether the top and middle
shelves are parallel. (2 points)
Answer:
The top and middle shelves are parallel.
Step-by-step explanation:
<1 and <5 are corresponding angles.
When two lines are cut by a transversal such that corresponding angles are congruent, the lines are parallel.
If angles 1 and 5 are congruent, the shelves are parallel.
We are given m<5 = 60°.
Also, m<2 = 120°.
Angles 1 and 2 are a linear pair and are supplementary.
The measures of angles 1 and 2 add to 180°.
m<1 + m<2 = 180°
m<1 + 120° = 180°
Subtract 120° from both sides.
m<1 = 60°
m<1 = m<5 = 60°
Since angles 1 and 2 have the same measure, 60°, angles 1 and 2 are congruent.
Answer: The top and middle shelves are parallel.
In the figure below, m <2=49
The measure of angles ∠1, ∠3, and ∠4 will be 131°, 131°, and 49°, respectively.
Given that:
∠2 = 49°
The measure of angle ∠1 is calculated as,
∠1 + ∠2 = 180°
∠1 + 49° = 180°
∠1 = 131°
The measure of the angles ∠3 and ∠4 is calculated as,
∠3 = ∠1
∠3 = 131°
∠4 = ∠2
∠4 = 49°

The recommended dosage of oxacillin is 35 mg/kg/day to be administered q6hr. The child weighs 10 kg. The total daily dose would be:
The amount for one dose of IV vancomycin for this child is 350 mg.
The recommended dosage of IV vancomycin is 40 mg/kg/day divided q6h.
The child weighs 35 kg.
To calculate the amount for one dose, we need to first calculate the total daily dose and then divide it by the number of doses per day.
Total daily dose = 40 mg/kg/day x 35 kg = 1400 mg/day
Since the medication is divided q6h (every 6 hours), there are 4 doses per day.
Amount for one dose = Total daily dose / Number of doses per day
= 1400 mg/day / 4 doses per day
= 350 mg/dose
Therefore, the amount for one dose of IV vancomycin for this child is 350 mg.

What is the law of sines?Suppose we have a triangle in which:
Side with a length of a is opposite to angle A.Side with a length of b is opposite to angle B.Side with a length of c is opposite to angle C.The lengths and the sine of the angles are related as follows:
[tex]\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}[/tex]
Considering the triangle in this problem, the relation is given as follows:
sin(D)/18 = sin(40º)/24.2.
Hence the measure of angle D is obtained as follows:
sin(D) = 18 x sine of 40 degrees/24.2
sin(D) = 0.4781
m < D = arcsin(0.4781)
m < D = 28.6º.
The sum of the internal angle measures of a triangle is of 180º, hence the measure of angle F is obtained as follows:
m < F + 40 + 28.6 = 180
m < F = 180 - (40 + 28.6)
m < F = 111.4º
Then the length f is obtained as follows:

The length of each side of the square is about
units, and the length of its diagonal is about
units.
Answer:
19.8 units
Step-by-step explanation:
From the diagram attached, to find the length of side AB, we need to use Pythagoras theorem on the right triangles. We can see that AB is the base of the two right triangle.
For the first right triangle with hypotenuse of 13 and height of 12, let x be the base, therefore using hypotenuse:
13² = 12² + x²
169 = 144 + x²
x² = 169 - 144
x² = 25
x = √25 = 5
For the second right triangle with hypotenuse of 15 and height of 12, let y be the base, therefore using hypotenuse:
15² = 12² + y²
225 = 144 + y²
y² = 225 - 144
y² = 81
y = √81 = 9
The length of AB = x + y = 9 + 5 = 14 unit
Since for a square all the sides are equal, therefore the length of each side of the square ABCD is 14 units.
In triangle ADC, the hypotenuse = AC, AD = DC = 14 unit. Using Pythagoras:
AC² = AD² + DC²
AC² = 14² + 14²
AC² = 196 + 196 = 392
AC = √392 = 19.8
The length of its diagonal is about 19.8 units

perimeter of the parallelogram = 15ft + 15ft + 30ft + 30ft
perimeter of the parallelogram = 90 ft
In calculating for the area of parallelogram, the base is multiplied by the height, as the same way for calculating the area of a rectangle.
height of the parallelogram = 30ft × tan 45°
height of the parallelogram = 30ft {recall tan 45° = 1}
area of the parallelogram = 30ft × 30ft
area of the parallelogram = 900 ft²
Therefore, the perimeter of the parallelogram is 90 ft while it's area is calculated to be 900 square feet.
