What we are given:
49x - 21y = -1,470
we need to keep y on the left side so we subtract 49x from both sides;
-49x -49x
-21y = -49x - 1,470
we need to make y one so we divide by -21 from both sides;
÷-21 ÷-21
y = -49x/-21 - 70
which simplifies to
y = 7x/3 - 70

Find the length of each arc. Round your answers to the nearest tenth.
r=r= 32 km
θ=θ=38°°
The length of each arc, given a radius of 32 km and an angle of 38 degrees, is approximately 21.0 km.
To find the length of each arc, we can use the formula:
arc length = (θ/360°) × 2πr.
Plugging in the given values, we have:
arc length = (38°/360°) × 2π(32 km).
Simplifying the equation, we get:
arc length = (0.1056) × 2π(32 km).
Using the value of π as approximately 3.14159, we can calculate:
arc length = (0.1056) × 2(3.14159)(32 km).
Evaluating the expression, we find:
arc length ≈ 21.0 km (rounded to the nearest tenth).
Therefore, the length of each arc, given a radius of 32 km and an angle of 38 degrees, is approximately 21.0 km.

____ cutover involves more risk than other changeover methods.
A) Direct
B) Pilot
C) Parallel
D) Phased
Direct cutover involves more risk than other changeover methods. So, the correct option is A) Direct cutover.
A direct cutover is a changeover method where the old system is completely replaced by the new system at a specific point in time. This means that the new system becomes operational abruptly, and the old system is immediately discontinued. It does not involve running both systems in parallel or gradually phasing out the old system.
Direct cutover carries a higher level of risk compared to other changeover methods because of its immediate and complete switch to the new system. Since there is no parallel operation or gradual transition, any issues or problems with the new system can have a significant impact on the organization's operations. If the new system encounters unexpected errors, data loss, or other technical difficulties, it can disrupt business processes and cause downtime.
The absence of a fallback option or a safety net during a direct cutover makes it riskier. If any critical issues arise, it can be challenging to revert to the old system quickly, leading to potential financial losses, customer dissatisfaction, and operational disruptions.

The value of x is equal to 15°
How to determine the value of x?In Mathematics and Geometry, the sum of the exterior angles of both a regular and irregular polygon is always equal to 360 degrees.
Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.
By substituting the given parameters, we have the following:
3x + 4x + 8 + 5x + 5 + 6x - 1 + 5x + 3 = 360°.
3x + 4x + 5x + 6x + 5x + 8 + 5 - 1 + 3 = 360°.

Lana had 475 Pokemon cards. She gave her little brother 125 of her cards. What percentage of her cards did Lana give away?
So, Lana gave away 26.32% of he Pokemon cards to her little brother.
To find the percentage of cards Lana gave away, we can use the formula:(Quantity given away / Total quantity) * 100.
In this case, Lana gave away 125 cards out of her total collection of 475 cards.Plugging these values into the formula, we have:
(125 / 475) * 100 = 0.2632 * 100 = 26.32%.
Lana gave away 26.32% of her Pokemon cards to her little brother.
Alternatively, we can calculate the percentage by subtracting the remaining cards from the total and finding the ratio:
Percentage given away
= (Cards given away / Total cards) * 100

Jai's family took a road trip to Mount Rushmore. Jai fell asleep after they had
travelled 259 miles. If the total length of the trip was 740 miles, what
percentage of the total trip had they travelled when Jai fell asleep?
The total percentage they travelled when Jai fell asleep is 35%.
In mathematics, a percentage is a ratio or value that is expressed as a fraction of 100. The Latin term "per centum," which means "by a hundred," is the source of the English word "percent." The sign "%" stands for percentage. We apply the percentage method to determine the portion of a whole expressed in terms of 100. Use the percentage formula to convert a number to a fraction of 100.
The total length of trip was 740 miles.
Jai travelled before they fell asleep = 259 miles
Therefore the percentage of total trip travelled before Jai fell asleep =
= \(\frac{259}{740}\times100\)
= 35 %

Answer:
Domain = {x | x is a real number}
Look at the step-by-step explanation to get a better understanding
Step-by-step explanation:
Domain = {x | x is a real number}
The function shown f(x)=5^x-7 is an exponential function with a vertical shift of -7 units (shift downwards). Nevertheless, it is an exponential function.
Domain is the set of x-values that we can put into the function. Exponential functions of this type have a domain of "all real numbers". If you see the function, you can figure out that we can put any real number and still there will be no "undefined" or "division by zero" cases.
Thus, this function's domain is the set of all real numbers.

A factory employee fills a box with cans of paint. The box is in the shape of a rectangular prism and each can of paint is in the shape of a cylinder. The sizes of the box and a can of paint are shown below. After the employee places 3 cans of paint into the box, approximately how much empty space will remain in the box?
To determine the amount of empty space in the box after three cans of paint are placed inside, we need to calculate the volume of the box and the volume of three cans of paint and subtract the latter from the former.
Explanation:
The box is a rectangular prism with dimensions of length 16 inches, width 12 inches, and height 10 inches. The can of paint is a cylinder with a diameter of 3 inches and a height of 4 inches. The volume of the box is found by multiplying the length, width, and height of the box:
Volume of box = 16 in x 12 in x 10 in = 1,920 cubic inches.
The volume of one can of paint is found by using the formula for the volume of a cylinder:
Volume of one can = πr^2h = 3.14 x (1.5)^2 x 4 = 28.26 cubic inches.
Therefore, the volume of three cans of paint is:
Volume of three cans = 3 x 28.26 = 84.78 cubic inches.
Finally, to determine the amount of empty space in the box after three cans of paint are placed inside, we subtract the volume of the three cans from the volume of the box:
Empty space in the box = Volume of box - Volume of three cans = 1,920 - 84.78 = 1,835.22 cubic inches (rounded to two decimal places).
Therefore, approximately 1,835.22 cubic inches of empty space will remain in the box after three cans of paint are placed inside.

Show that x=0 is a regular singular point of the given differential equation
b. Find the exponents at the singular point x=0.
c. Find the first three nonzero terms in each of two solutions(not multiples of each other) about x=0.
xy'' + y = 0
The first three nonzero terms of two linearly independent solutions about x = 0 can be obtained by Taylor expanding the solutions in terms of the exponent r and truncating the series to the desired order.
To determine if x = 0 is a regular singular point of the differential equation xy'' + y = 0, we substitute y = x^r into the equation and solve for the exponent r. Differentiating y twice with respect to x, we have y'' = r(r - 1)x^(r - 2). Substituting these expressions into the differential equation, we get \(x(x^r)(r(r - 1)x^(r - 2)) + x^r = 0\). Simplifying, we obtain r(r - 1) + 1 = 0, which yields r^2 - r + 1 = 0. Solving this quadratic equation, we find that the exponents at the singular point x = 0 are complex and given by r = (1 ± i√3)/2.
To find the first three nonzero terms of two linearly independent solutions about x = 0, we can use the Taylor series expansion. Let's consider the solution y1(x) corresponding to the exponent r = (1 + i√3)/2. Expanding y1(x) as a series around x = 0, we have y1(x) =\(x^r = x^((1 +\)i√3)/2) = x^(1/2) *\(x^(i√3/2\)). Using the binomial series expansion and Euler's formula, we can write \(x^(1/2) and x^(i√3/2)\) as infinite series.
