Answer:

Step-by-step explanation:
Planck relation
\(\large\boxed{E = hf}\)
where:
E = Energy of the photon (J).h = Planck's constant (J · s).f = frequency of light produced (Hz).Given values:
E = 3.4 × 10⁻¹⁹ Jh = 6.626 × 10⁻³⁴ J · sSubstitute the given values into the formula and solve for f:
\(\implies 3.4 \times 10^{-19}=(6.626 \times 10^{-34})f\)
\(\implies f=\dfrac{3.4 \times 10^{-19}}{6.626 \times 10^{-34}}\)
\(\implies f=\dfrac{3.4}{6.626} \times \dfrac{10^{-19}}{10^{-34}}\)
\(\implies f=0.5131\times 10^{(-19-(-34))}\)
\(\implies f=0.5131 \times 10^{15}\)
\(\implies f=5.131 \times 10^{14}\)

2. Mrs.Kaushik has a square plot with the measurement as shown in the figure. She wants to construct a house in the middle of the plot. A garden is developed around the house. Find the total cost of developing a garden around the house at the rate of Rs. 55 per m^2.
Answers
Answer:
Hence the total cost of developing a garden is around Rs. 17,875.
Step-by-step explanation:
Side of the square plot = 25 m
Formula: Area of the square plot = square of the side = (side)2
= (25)2 = 625
Therefore the area of the square plot is 625 m2
Length of the house = 20 m and
The breadth of the house = 15 m
Area of the house = length×breadth
= 20×15 = 300 m2
Area of the garden = Area of the square plot – Area of the house
= 625–300 = 325 m2
∵ The cost of developing the garden per sq. m is Rs. 55
The cost of developing the garden 325 sq. m = Rs. 55×325
= Rs. 17,875
Hence the total cost of developing a garden is around Rs. 17,875.

A regular hexagon is inscribed in a circle with a diameter of 12 units. Find the area of the hexagon. Round your answer to the nearest tenth. (there's no picture included)
Answers
Answer:
93.5 square units
Step-by-step explanation:
Diameter of the Circle = 12 Units
Therefore:
Radius of the Circle = 12/2 =6 Units
Since the hexagon is regular, it consists of 6 equilateral triangles of side length 6 units.
Area of the Hexagon = 6 X Area of one equilateral triangle
Area of an equilateral triangle of side length s = \(\dfrac{\sqrt{3} }{4}s^2\)
Side Length, s=6 Units
\(\text{Therefore, the area of one equilateral triangle =}\dfrac{\sqrt{3} }{4}\times 6^2\\\\=9\sqrt{3} $ square units\)
Area of the Hexagon
\(= 6 X 9\sqrt{3} \\=93.5$ square units (to the nearest tenth)\)
if the relation represents a function, find the domain and range. (enter your answers using interval notation. if the relation is not a function, enter none in the domain and range answer blanks.)
Answers
If the relation is represented by the equation y = 2x + 1, the domain would be all real numbers (-infinity, +infinity) and the range would be all real numbers greater than or equal to 1 (1, +infinity).
A relation is a function if for every input (x) there is exactly one output (y). To determine if a relation is a function, we can use the vertical line test, which states that if a vertical line can be drawn through the graph and intersects the relation more than once, then the relation is not a function.
If the relation is a function, we can find the domain and range by analyzing the relation. The domain is the set of all x-values and the range is the set of all y-values. In interval notation, the domain is written as (a, b) and the range is written as (c, d).
So, the domain and range answers depend on the relation which is given and it should be specified.

To finish it, using the unitary method. Additionally, after the value of a single unit has been established, we can multiply that value by the quantity of additional units required to establish the value of the additional units. This is typically how the concepts of ratio and proportion are used.

A polynomial is considered rational if it can be written as a polynomial divided by a polynomial.
What is meant by rational function?Any function that can be expressed as a rational fraction in mathematics—an algebraic fraction in which the numerator and denominator are both polynomials—is referred to as a rational function.
Here,

A college administrator predicts that the proportion of students that are nursing majors is greater than 40%. To test this, a group of 400 students are randomly selected and it's determined that 190 are nursing majors. The following is the setup for this hypothesis test:
H0:p=0.40
Ha:p>0.40
In this example, the p-value was determined to be 0.001. Find the conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%)
Answers
Answer:
Step-by-step explanation:
Using the following data:
H0:p=0.40 (null hypothesis)
Ha:p>0.40 (alternative hypothesis)
The p-value was determined to be 0.001.
a significance level of 5%
Since the p value (0.001) is less than the significance level (0.05), we will reject the null hypothesis and then we would conclude that the proportion of students that are nursing majors is greater than 0.4.
Answer:
p value= 0.131
Step-by-step explanation:
Since we have calculated the test statistic, we can now proceed to find the p-value for this hypothesis test.Using the test statistic and since the hypothesis test is a left tailed test, the p-value will then be the area under the standard normal curve to the left of the test statistic of -1.12.Using the Standard Normal table given above, the area under the standard normal curve to the left of the test statistic of -1.12 is 0.131 (rounded to 3 decimal places.Thus the p-value = 0.131.
How would you describe the relationship between the real zero(s) and x-intercept(s) of the function
f(x) =
3x(x - 1)
x2(x+3)(x + 1)
When you set the function equal to zero, the solution is x = 1; therefore, the graph has an x-intercept of (1,0).
O When you set the function equal to zero, the solutions are x = 0 or x = 1; therefore, the graph has x-intercepts at
(0, 0) and (1,0).
O When you substitute x = 0 into the function, there is no solution, therefore, the graph will not have any X-
intercepts.
Since there are asymptotes at x = -3, x = -1, and x = 0, the graph has no x-intercepts and therefore, no real
zeros.
Answers
The description of the relationship between the real zero(s) and x-intercept(s) of the function should be option A.

Answers
In the function f(x) = log2(x + 3)), the smallest average rate of change in the function is in the interval, (6,8)
What is a logarithmic function ?The logarithmic function is an expression which we can write as, y = logₐx, where a>0 & x>0, It is the inverse of exponential function.
Formulae for logarithmic function are,
LogAB = LogA + LogB
Logₐaᵇ = b
Given that,
A logarithmic function,
f(x) = = log2(x + 3)
Rate of change = Change in values of function/change in x
= [F(b) - F(a)]/ b-a
For the interval, (0, 2)
f(0) = Log2(0 + 3) = Log(6)
f(2) = Log2(2 + 3) = Log(10)
Rate of change = Log(10) - Log(6) /2

Describe the motion of a particle with position (x, y) as t varies in the given interval. (For each answer, enter an ordered pair of the form x, y.) x = 1 + sin(t), y = 6 + 2 cos(t), π/2 ≤ t ≤ 2π The motion of the particle takes place on an ellipse centered at (x, y) = 1,6 . As t goes from π/2 to 2π, the particle starts at the point (x, y) = 1,6 and moves clockwise three-fourths of the way around the ellipse to (x, y) = .
Answers
Two foci of the ellipse are ( 2 - √3) and moves clockwise three fourth is ( 2 + √3).
As given in the question,
Given equations are :
x = 1 + sin(t)
⇒ sin(t) = (x - 1)
y = 6 + 2cos(t)
⇒cos(t) = (y - 6)/2
We know that,
sin²t + cos²t = 1
Substitute the value of sin(t) and cos(t) we get,
(x - 1)²/ 1² + (y - 6)²/ 2² = 1
Standard Equation of the ellipse is:
( x -h)²/b² + (y - k)²/a² = 1
Center of the ellipse = (h , k)
(h , k) = (1, 6)
here b = 1 and a = 2
'c' is the distance from focus to the center
c = √a² - b²
= √4 -1
= √3
Therefore , two foci for the given ellipse are ( 2 - √3) and moves clockwise three fourth is ( 2 + √3).

Let x be the number of points Aisha has.
Then, according to the problem statement, we know that:
Carter has 7 1/2 more points than Aisha, so he has
x + 7 1/2 points.
Jamila has 4 - 1/2 more points than Carter, so she has
x + 7 1/2 + 4 - 1/2 points,

Jamila has 26 points, so we can set x + 11 equal to 26 and solve for x:
