C = 5/9(F-32)
Could someone help me with figuring this out?
Josh is talking on the phone to his friend Greg who lives in Europe. Greg is used to describing temperatures in °C, while Josh is used to describing temperatures in °F. Greg can use the formula above to quickly convert the temperatures Josh describes to °C.
How can you rewrite the formula so that Josh can quickly convert the temperatures that Greg describes to °F? Justify your solution method.
Answer:
F = 9/5C +32
Step-by-step explanation:
You want to rearrange C = 5/9(F-32) to make F the subject.
SolutionYou can solve for F the same way you solve any similar 2-step equation:
C = 5/9(F -32) . . . . . . given
9/5C = F -32 . . . . . . . multiply by 9/5 (multiplication property of equality)
9/5C +32 = F . . . . . . add 32 (addition property of equality)
The equation Josh can use to convert to °F is ...
F = 9/5C +32
Match each radius to the exact area of the circle with the radius
Areas of Circles are for [tex]490.873m^2[/tex] radius 12.5m, [tex]706.858m^2[/tex] for radius 15m, [tex]1256.637m^2[/tex] for radius 20m.
What is area of a circle?The region encircled by a circle with radius r is known as πr² in geometry. Here, the Greek letter stands for the constant proportion of a circle's circumference to its diameter, which is roughly equivalent to 3.14159.
This formula, which was first discovered by Archimedes, can be derived by considering the circle as the boundary of a series of regular polygons. A regular polygon's area is equal to half its perimeter times the distance from its center to its sides. The equivalent formula, [tex]A=\frac{1}{2} *2\pi r*r[/tex] states that the area is equal to half the perimeter times the radius.
The limit for a circle is held by [tex]\pi r^{2}[/tex].
Calculation:Given;
1) r=12.5m
[tex]A=\pi r^2=\pi (12.5)^2=490.873m^2[/tex]
2) r=15m;
[tex]A=\pi r^2=\pi (15)^2=706.858m^2[/tex]
3) r=20m;

A cargo ship left port a and is headed across the ocean to shipping port b. After one month, the ship stopped at a refueling station along a path described by a vector with components leftanglebracket 14, 23 rightanglebracket. After another month, on the same path, the ship reached port b, twice the distance from port a as the fueling station. What are the characteristics of the vector representing the path of the ship?.
Answer:
Step-by-step explanation:
The vector representing the path of the ship from port A to the refueling station has components <14, 23>, and the vector representing the path from the refueling station to port B has twice the magnitude as the vector from port A to the refueling station.
To find the characteristics of the vector representing the path of the ship from port A to port B, we can add the two vectors together.
The sum of two vectors <a, b> and <c, d> is given by <a+c, b+d>. Therefore, the vector representing the path of the ship from port A to port B is given by:
<14, 23> + 2*<14, 23> = <14+214, 23+223> = <42, 69>
The vector representing the path of the ship from port A to port B is <42, 69>. This vector has a magnitude of √(42^2 + 69^2) = √(1764 + 4761) = √(6525) = 81 and a direction given by the angle theta, where tan(theta) = 69/42.

Is a length of two sides of an isosceles triangle is 4 cm and 10 cm then the length of the third side?
The length of the third side of an isosceles triangle with sides 4 cm and 10 cm is 10 cm.
We know that in an isosceles triangle, two sides are equal.
One side of the triangle is 4 cm and the other is 10 cm.
Let us consider the third side to be 4 cm,
then 4 cm + 4cm = 8 cm and it is not greater than the third side 10 cm.
Hence, the third side cannot be 4 cm.
Then the third side can be 10 cm,
therefore, 4 cm + 10 cm = 14 cm > 10cm
and 10 cm + 10 cm = 20 cm > 10 cm.

How to obtain the slope of a linear function?The slope of a linear function, given two points, is given as the division of the change in y by the change in x.
The numeric values for these functions are given as follows:
f(0) = 2 cot(0) = 2 cos(0)/sin(0) = undefined, as sin(0) = 0, and we cannot divide by 0.g(π) = sin (π/2) = 1. the sine of 90 degrees is of one on the trigonometric circle.Hence the points are given as follows:
(0, undefined) and (π, 1).
The undefined point means that there is a vertical asymptote at x = 0, meaning that the change in y is undefined, and thus the slope of the function is also undefined.

What is the multiplicity of 0?
The multiplicity of 0 is the number of times that 0 appears as a root of a polynomial equation.
In other words, it is the number of times that 0 is a solution to the equation. For example, the equation x^2 - 4x + 4 has two solutions, 0 and 4. The multiplicity of 0 is therefore 2, since 0 is a repeated solution.
If a polynomial equation has only one 0 as a solution, the multiplicity of 0 is 1. In some cases, a polynomial equation may have no 0s as a solution, in which case the multiplicity of 0 is 0.
In general, the multiplicity of a number is the number of times it appears as a solution to a polynomial equation. For example, the equation x^2 - 2x + 8 has two solutions, 2 and 4. The multiplicity of 2 is 1, since 2 appears only once as a solution, while the multiplicity of 4 is 2, since 4 appears twice as a solution.

Lea wants to make two pillows for her new couch. She needs 314 square yards of fabric for the first pillow and 112 square yards of fabric for the second pillow. Lea wants to know how much fabric she will have to buy for both pillows. Which expression represents the total number of square yards of fabric she needs for both pillows?.
The equation for the total square yards of cloth she needs for both pillows is 314+112=426.
The total number of square yards of fabric Lea needs for both pillows is the sum of the fabric needed for the first pillow and the fabric needed for the second pillow. This can be represented by the expression:
314 square yards + 112 square yards = 426 square yards
Therefore, the expression that represents the total number of square yards of fabric Lea needs for both pillows is:
314 + 112 = 426
This expression would simplify to 426 square yards. This expression uses the addition operator (+) to add the two quantities of fabric that Lea needs for each pillow. The result is the total number of square yards of fabric that she needs for both pillows.

Which is a valid theorem to show two triangles are congruent?
(Option D.) The Side-Side-Side (SSS) Theorem: If three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent.
Showing Two Triangles are Congruent with the SSS TheoremThe Side-Side-Side (SSS) Theorem is a valid theorem to show that two triangles are congruent. This theorem states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent.
In other words, if all three of the sides of one triangle are equal in length to all three of the sides of another triangle, then the two triangles are identical in size and shape.

How will you know if a function increases and decreases?
A function increases if the output value of function increases on increasing the input value and the function decreses if the output value of function decreases on increasing the input value
As we know a function is nothing but a relation between input values and output values where each input has exactly one output.
Consider a function y = f(x)
For a given function if the value of y increases on increasing the value of x, then the function is an increasing function
If the y-value decreases on increasing the value of x, then the function is a decreasing function.
Another method is that if we need to determine whether a function f(x) is increasing or decreasing at point 'a'.
If a function is differentiable on an open interval, we calculate the derivative of function f(x)
If the derivative f′(x) > 0 on an open interval, then function f(x) is increasing on that interval.
If the derivative f′(x) < 0 on an open interval, then function f(x) is decreasing on that interval.
Therefore, if the output value of function increases on increasing the input value then the function is an increasing function and if the output value of function decreases on increasing the input value then the function is an decreasing function.

What is the y-intercept of 2x y =- 3?
The y-intercept of the equation 2x - y = -3 is 3 and in ordered pair form is (0,3).
What is the y-intercept of the given equation?The slope-intercept formula is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the equation in the question
2x - y = -3
First, we solve form for y and reorder in slope intercept form.
2x - y = -3
Subtract 2x from both sides
2x - 2x- y = -3 - 2x
- y = -3 - 2x
Divide each term by -1
y = 3 + 2x
Reorder in slope intercept form
y = 2x + 3
To find the y-intercept, replace x with zero and solve for y
y = 2(0) + 3
y = 3
Therefore, the y-intercept is 3.
