a. 3
b. 25
c. 1,168
d. 62,034
Answers
1) Note that when x = 7, then the second coordinate is y = 112.8. (Option d)
2) the approximate value of where x =4 given the function above is 3 (Option a)
What is the explanation for the above?A) by logical deduction, if on the table, x and y values are given, then they retain those positions as coordinates on the graph. Hence, when x = 7, then the second coordinate is y = 112.8.
b) to find the approximate value of y for x = 4, we can use the equation given:
log y = 0.75821x + 0.03442
Substituting x = 4:
log y = 0.75821(4) + 0.03442
Simplifying:
log y = 3.03284 + 0.03442
log y = 3.06726
log y = 3 (Option A)

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.

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)
Answers
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.

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)
Answers
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)

Answers
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 prism is a right hexagonal prism.
The lateral area of the right hexagonal prism is 1008 square centimeters.
The sum of the area of a regular hexagon is 187.06 cm².
The surface area of the prism is 1196.06 cm².
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.
= 2 x 93.53
= 187.06 cm²
10)
There are 6 surfaces.
Each surface is in rectangular shape.
So,
Surface area
= 6 x (12 x 14)
= 1008 cm²
And,
The surface area of the prism.
= 1008 + 187.06
= 1196.06 cm²
Therefore,
The prism is a right hexagonal prism.
The lateral area of the right hexagonal prism is 1008 square centimeters.
The sum of the area of a regular hexagon is 187.06 cm².

Ezekiel spends t hours each night on his homework and 1/4

a. h = 5/4t
b. h = t/20
c. h = 20/t
d. h = 5t/4
Answers
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,
Therefore, the correct option is (d).

Triangle ABC is translated to image A′B′C′. In this translation, A(5, 1) maps to A′(6, –2). The coordinates of B′ are
(–1, 0). What are the coordinates of B?
Answers
Answer:
We know that point A(5, 1) maps to A'(6, -2) in the translation. To find the translation vector, we can subtract the coordinates of A from the coordinates of A':
Translation vector = A' - A = (6, -2) - (5, 1) = (1, -3)
This means that every point in the preimage moves 1 unit to the right and 3 units down to reach its corresponding point in the image.
We also know that point B'(−1, 0) is the image of a point B in the preimage. To find the coordinates of point B, we can apply the translation vector to B':
B = B' - Translation vector = (-1, 0) - (1, -3) = (-2, 3)
Therefore, the coordinates of point B in the preimage are (-2, 3).

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
