a line has this equation y=-1/2x+5 what is the equation for the perpendicular line that goes through (10,3)
Answer:
Y=2x-17
Step-by-step explanation:
If a line is perpendicular it means their slope is reciprocal to each other.
Y=-1/2X+5 has a slope of -1/2
The function that is perpendicular will have a slope of 2.
Y=2x+b
Plug in(10,3)
2(10)+b=3
b=-17
Y=2x-17

What is the inverse of φ?
The inverse of a function is a function that "undoes" the original function. If f is a function and x is an element in the domain of f, then the inverse of f is denoted as f^-1(x) and is defined as the element in the domain of f such that f(f^-1(x)) = x.
The symbol "φ" (phi) is not a commonly used notation for any function. It is a Greek letter and can be used in different fields such as physics, mathematics, and engineering to represent different things depending on the context.
It is important to note that not all functions have inverses. A function has an inverse only if it is a bijective function, which is a function that is both injective and surjective, meaning that it maps every element of the domain to a unique element in the range and vice-versa.
So to find the inverse of a function, you have to first make sure that the function is bijective. If so, you can find the inverse function by switching the positions of x and y, then replacing y with f^-1(x) or x with f^-1(y) and solving for the new x or y.

Right triangle ABC is similar to right triangle DEF. If the side lengths for triangle ABC are 15, 20 and 25, respectively, which values could represent the side lengths of triangle DEF
Answer:
D. 18, 24, 30
Step-by-step explanation:
The easy way to do this is to look for the answer with equal differences between the numbers:
24-18 = 6
30-24 = 6
We can do this because we know the triangles are similar. The difference between 15, 20 and 20, 25 is equal.
What is the x-intercept of the line 4x y =- 4?
The x-intercept of the line 4x-y =- 4 is (1,0).
At x-intercepts, y=0 and at
y-intercepts, x=0.
So, to find the,
x-intercept, set y=0
4x−0=4
4x=4
x=1.
The points at which the graph of a function or an equation crosses or "touches" the x-axis of the Cartesian Plane are referred to as the x-intercepts. This could be thought of as a point with a y-value of zero. Let y equal 0 and then solve for x to determine the equation's x-intercepts.
Because the line crosses the x-axis when y=0, the equation for x must be solved in order to determine the x-intercept. We can solve for the intercepts when an equation is not in the form y = mx + b by solving for the remaining variable and plugging in 0 as necessary. To locate the y-intercept: solve for y and set x to zero.

A cylinder shaped dispenser holds 5,652 cubic centimeters of liquid soap and is now full. The radius of the dispenser is 7.5 centimeters. What is the difference between the height of the soap in the full dispenser and the height when 4,239 cubic centimeters of soap remains in the dispenser
On solving the provided question, we can say that difference of cylinder between the height of the soap 8 cm.
what is cylinder?One of the most fundamental curved geometric forms is the cylinder, which is often a three-dimensional solid. It is referred to as a prism with a circle as its base in elementary geometry. Several contemporary fields of geometry and topology also define a cylinder as an indefinitely curved surface. A three-dimensional object known as a "cylinder" consists of curving surfaces with circular tops and bottoms. A cylinder is a three-dimensional solid figure that has two bases that are both identical circles joined by a curving surface at the height of the cylinder, which is determined by the distance between the bases from the center. Examples of cylinders are cold beverage cans and toilet paper wicks.
[volume of cylinder]=pi*r²*h- = h=[volume of cylinder]/(pi*r²)
Volume=5652 cm³
r=7.5 cm, so, h= [tex][5652]/(3.14*7.5²) = h=32 cm[/tex]
the height of the soap in the full dispenser is 32 cm
the height when 4,239 cubic centimeters of soap remains in the dispenser is h [tex]=[4239]/(3.14*7.5²) = h=24 cm[/tex]
the difference is [tex]32-24 = 8 cm[/tex]

Angie is working on solving the exponential equation 23x = 6; however, she is not quite sure where to start. Using complete sentences, describe to Angie how to solve this equation.
Hint: Use the change of base formula: log base b of y equals log y over log b.
Step-by-step explanation:
I'm assuming that its 23 to the power x since you said it is an exponential equation.
as for the hint there is no specific base specified so I'll do the best I can with the answer.
Angie can begin solving by applying log to the base 23 on both sides. when this is done, Angie will be left with:
[tex] log_{23}( {23}^{x} ) = log_{23}(6) [/tex]
and as we know the power rule in logarithms allows us to remove the power within the expression.
hence, we'll get:
[tex]x log_{23}(23) = log_{23}(6) [/tex]
furthermore, if we have the same number and base within a logarithmic expression it will simply become 1 giving us the final answer:
[tex]x = log_{23}(6) [/tex]

K
Step-by-step explanation:
KLH is a triangle, and the sum of all angles in a triangle is 180°.
now, we know the angle at L = 134°.
because of the symmetry of the angles in such a regular parallelogram, the upper angle at H is 25°, and the lower angle at H (one of the angles in our triangle) is (4x + 9)°.
and the upper angle at K is (4x + 9)°, and the lower angle at K is 25°.
so, we have
180 = 134 + 25 + (4x + 9) = 159 + 4x + 9 = 168 + 4x

A quantity with an initial value of 7800 decays continuously at a rate of 0. 1%
per hour. What is the value of the quantity after 1. 25 days, to the nearest
hundredth?
The question is asking for the value of a quantity that decays continuously at a rate of 0.1% per hour. We are given that the initial value of the quantity is 7800 and are asked to find the value after 1.25 days (30 hours).
What is a ratio in mathematics?
A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
We can use the following formula to find the final value of the quantity after a certain amount of time:
final value = initial value * (1 - decay rate)^time
Where decay rate is given as a decimal (0.1% = 0.001)
Plugging in the given values, we get:
final value = 7800 * (1 - 0.001)^30
The final value is around 7396.65
Rounding the final value to the nearest hundredth, the final value after 1.25 days is:
7396.65 ≈ 7396.66
The value of the quantity after 1.25 days, to the nearest hundredth is 7396.66.

The average age of a university student was found to be 24 with a standard
deviation of 2. What age group is within 2 standard deviations of the mean?
The age group that falls between two standard deviations is 20 to 28.
What is the standard deviation?The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean.
Given, The average age of a university student was found to be 24 with a standard deviation of 2.
Therefore, age group is within 2 standard deviations of the mean is,
24 + 2×2 = 24 + 4 = 28,
And 24 - 2×2 = 24 - 4 = 20.

Two angles are a linear pair. Their measures are represented by x+10 and 3x+10. What are the measures of the angles
Answer:
50° and 130°
Step-by-step explanation:
Linear pair of angles are supplementary, which means their sum is 180
x + 10 + 3x + 10 = 180
4x + 20 = 180
4x = 160
x = 40
x + 10 = 40 + 10 = 50°
3x + 10 = 3(40) + 10 = 120 + 10 = 130°
