2. At what angle measures (x-axis values) is the sine graphs at its minimum (lowest point)
3. At what angle measures )x-axis values) does the sine graph cross the y-axis
4. At what (x-axis values) does the sine graph cross the z-axis?
5. For what angle measures (x-axis values) is the sine graph equal to or above the z-axis
Possible answers for all
0,90,180,270,360,-90,-270,-360,-180
The sine graph is at its maximum when the angle measure is an odd multiple of 90 degrees.
The sine graph crosses the y-axis at x = 0.
The sine graph is at its maximum when the angle measure is an odd multiple of 90 degrees, or equivalently, an odd multiple of π/2 radians.
The sine graph is at its minimum when the angle measure is an even multiple of 90 degrees, or equivalently, an even multiple of π/2 radians.
The sine graph crosses the y-axis at x = 0.
At this point, the sine function has a value of 0.
The sine graph does not cross the z-axis.
The z-axis is the axis perpendicular to the x-y plane, and the sine graph oscillates between positive and negative y-values, but never crosses the z-axis.
The sine graph is equal to or above the z-axis whenever its y-value is non-negative.
This occurs whenever the angle measure is between 0 and π radians, or between 2π and 3π radians, or between 4π and 5π radians, and so on.

The resistance, R, of a wire varies as its length and inversly as the square of its diameter. If the resistance of a wire 700ft long with a diameter of 0.2inches is 15611ohms, what is the resistance of 1800ft of the same type of wire with a diameter of 0.45inches? (Leave k in fraction form or round to at least 3 decimal places. Round off your final answer to the nearest hundredths)
The resistance of 1800 feet of the same sort of wire with a 0.45in diameter is roughly 15037.45 ohms.
How to find the resistance of 1800ft of the same type of wire with a diameter of 0.45inchesLet R be the resistance of the wire,
L be the length of the wire,
d be the diameter of the wire, and
k be a constant of variation.
Then we have the equation:
R = k * L / d^2
Solving for k to find the resistance of a wire of varying length and diameter.
We can create an equation using the information provided:
15611 = k * 700 / 0.2^2
Solving for k, we get:
k = 15611 * 0.2^2 / 700
k ≈ 0.1799
Using k to calculate the resistance of a wire with a length of 1800 feet and a diameter of 0.45 inches:
15037.45 ohms = 0.1799 * 1800 / 0.452 R
As a result, the resistance of 1800 feet of the same sort of wire with a 0.45in diameter is roughly 15037.45 ohms.

The maximum grade allowed between two stations in a rapid transit rail system is 2.6% between station and station B, which are 260 feet apart. The tracks rise 5 feet. What is the grade of the track between the stations round answer to the nearest 10th.
The grade of the track between the stations is approximately 1.9%.
How to calculate the grade of the track between the stations round answer to the nearest 10th.The grade of the track is given as a percentage by the change in elevation (climb) divided by the horizontal distance (run) between the two stations:
(climb / run) x 100% = grade
We are given a 5 foot ascent and a 260 foot horizontal distance (run). When we enter these values into the formula, we get:

The missing side using the Pythagorean theorem is 10.2.
We have,
We see that,
Hypotenuse = 13
Base = x (say)
Height = 8
Now,
Applying the Pythagorean theorem,
Hypotenuse² = Base² + Height²
Substituting,
13² = x² + 8²
13² = 169
8² = 64
So,
169 = x² + 64
x² = 169 - 64

Use a graphing utility to find one set of polar coordinates of the point given in rectangular coordinates. Round your results to two decimal places.
(−9, 4)
The polar coordinates of the point (-9, 4) are approximately (9.85, -24.04°).
To find the polar coordinates (r,θ) corresponding to the rectangular coordinates (-9, 4), we can use the following formulas:
r = sqrt(x^2 + y^2)
θ = arctan(y/x)
Substituting the values x = -9 and y = 4, we get:
r = sqrt((-9)^2 + 4^2)
= sqrt(81 + 16)
= sqrt(97) ≈ 9.85
θ = arctan(4/-9)

A triangle is a three-sided polygon with three vertices. In this problem, we are given a triangle ABC with vertices A(−3, 3), B(0, 7), and C(−3, 0). The coordinates of the vertices represent the location of each vertex in the coordinate plane.
Using this method, we can determine the new coordinates of the vertices of the translated triangle. The options given for the new coordinates of the vertices are:
A′(−3, 0), B′(0, 4), C′(−3, −3)
A′(−3, 6), B′(0, 10), C′(−3, 3)
A′(−6, 3), B′(−3, 7), C′(0, 0)
A′(0, 3), B′(3, 5), C′(0, 0)
We can check each option by adding 3 to the y-coordinate of each vertex in the original triangle.
In the first option, the new coordinates of vertex A are (−3, 3+3) = (−3, 6), which matches the coordinates given in option 2.

a. h = 5/4t
b. h = t/20
c. h = 20/t
d. h = 5t/4
The equation that represents number of hours "h" which Ezekiel spend doing "math-homework" during the next 5 days is (d) h = 5t/4.
If Ezekiel spends 1/4 of his time on math homework, then he spends 3/4 of his time on other subjects. This means that out of every 4 hours he spends on homework, he spends 1 hour on math and 3 hours on other subjects.
So, in "t" hours, he will spend "t/4" hours on math homework.
To find the number of hours he will spend on math homework during the next 5 days, we multiply the time he spends on math homework in one day by the number of days.
⇒ Number of hours spent on math homework in 1 day = t/4,
⇒ Number of hours spent on math homework in 5 days = 5 × (t/4) = 5t/4,
The required equation is h = 5t/4,

In order to afford a down payment how much would Jocelyn need to save each year for the next three years to save $4000?
Jocelyn would need to save $1333.33 each year with 7% interest.
To calculate how much Jocelyn needs to save for the down payment over the next three years, we first need to determine the total down payment required. If the down payment is stated as $4000, then that is the total amount needed.
Assuming that Jocelyn wants to make the down payment in three years, we can calculate how much she needs to save each year by dividing the total down payment by three:
$4000 / 3 years = $1333.33 per year
So Jocelyn would need to save approximately $1333.33 each year for the next three years in order to have enough for the $4000 down payment.

The requried 3 1/2 cups of chocolate chips would be needed for 7 dozen cookies, so the answer is (c).
The ratio of chocolate chips to cookies is 1 1/2 cups for every 3 dozen cookies. To find how much chocolate chips are needed for 7 dozen cookies, we can use the following proportion:
1 1/2 cups / 3 dozen cookies = x cups / 7 dozen cookies
where x is the unknown amount of chocolate chips needed for 7 dozen cookies.
To solve for x, we can cross-multiply and simplify:
(1 1/2 cups) * (7 dozen cookies) = (3 dozen cookies) * x

We have,
7)
The prism is a right hexagonal prism.
8)
Perimeter = 6 x side length = 6 x 12 cm = 72 cm
Each rectangular face of the prism has a height of 14 cm and a width equal to one of the sides of the hexagon, which is 12 cm.
The area of each face.
= height x width
= 14 cm x 12 cm
= 168 cm²
And,
Lateral Area
= 6 x Area
= 6 x 168 cm²
= 1008 cm^2
9)
The formula for the area of a regular hexagon is given by:
Area = (3 x sqrt(3) / 2) x side length^2
Side length = 12 cm
Area = (3 x √(3) / 2) x 12²
Area = (3 x √(3) / 2) x 144
Area = 54 x √(3)
Area ≈ 93.53 cm² (rounded to two decimal places)
Now,
The sum of the area of a regular hexagon.
