What is the slope of the line that passes through the points (9,1) and (10,−1)? Write your answer in simplest form.
The slope of the linear equation that passes through the points (9,1) and (10,−1) is -2.
How to get the slope of the line?For a linear equation that goes through two points (x₁, y₁) and (x₂, y₂), the slope is given by the formula:
slope = (y₂ - y₁)/(x₂ - x₁)
In this case, we know that our line goes through the points (9,1) and (10, −1), so we can use these two values in the equation for the line, we will get:
slope = (-1 - 1)/(10 - 9) = -2/1 = -2
So the slope of the linear equation is -2.

There are 4 triangles and 2 circles. What is the simplest ratio of circles to total shapes?
Answer:
1:3
Step-by-step explanation:
circles:total
2:4+2
=2:6
=1:3
Reason
There are 2 circles and 4+2 = 6 shapes total.
The ratio of circles to total shapes is 2:6 which reduces to 1:3
The order is important since 3:1 is different from 1:3.
Anita's, a fast-food chain specializing in hot dogs and garlic fries, keeps track of the proportion of its customers who decide to eat in the restaurant (as opposed to ordering the food "to go"), so it can make decisions regarding the possible construction of in-store play areas, the attendance of its mascot Sammy at the franchise locations, and so on. Anita reports that 48% of its customers order their food to go. If this proportion is correct, what is the probability that, in a random sample of 50 customers at Anita's, exactly 3 order their food to go?
The probability that, in a random sample of 50 customers at Anita's, exactly 3 order their food to go is 0.3240
Probability:
The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes.
The value of the probability of an event to happen can lie between 0 and 1 because the favorable number of outcomes can never cross the total number of outcomes.

Dina goes to a carnival. Some rides at the carnival have a height requirement, but others do not. Dina is tall enough to go on all rides.
What is a mathematical question you can ask about this situation? What information would you need to know to answer your question?
The mathematical question that can be asked in a situation when Dina goes to a carnival and some rides have a height requirement is how many extra centimeters of height Diana has? The information required to solve this question is the required height for the ride and the height of Diana.
According to the question,
We need to ask a mathematical question. Let's solve a mathematical question in the given situation by taking one example.
If the required height to ride is 150 cm and the height of Diana is 165 cm, how many extra centimeters of height Diana has than the required height?
Solution:
Required height = 150 cm
Dian's height = 165 cm
Extra height = Diana's height - required height of the ride
Extra height = 165 cm - 150 cm
Extra height = 15 cm
Hence, in this supposed situation, Diana's height is 15 cm extra than the required height of the ride.

Write an equation of the parabola that has the same shape as the graph of f(x) = 4x², but with the point (10,4) as the vertex.
An equation of the parabola that has the same shape as the graph of f(x) = 4x², but with the point (10,4) as the vertex is y = 4x² - 80x + 404.
What is the vertex form of the parabola?The standard vertex form of the parabola is given by,y = a(x - h)² + k where (h, k) is the vertex.
Real numbers, a, h, and k are included here, where a ≠ 0. A point on the parabola is represented by the variables x and y, respectively.Given:
f(x) = 4x²
Vertex = (10,4)
a = 4
The value of a in the vertex form of the equation is taken to be 4 since the coefficients of x² must match for the parabola to have the same shape as the given parabola.
The equation can be written as,
y = a(x - h)² + k where (h, k) is the vertex.
Replacing the value of the vertex, we get
y = 4(x - 10)² + 4
y = 4(x² - 20x + 100) + 4
y = 4x² - 80x + 400 + 4
y = 4x² - 80x + 404

What is the equation of the parabola with focus at (1, 1) and directrix y = -1?
The equation of the parabola having focus (1,1) and directix y = -1 is
y = x²/4 - x/2 + 1/4
The focus of the parabola (h , k + p) = (1,1)
The directrix of the parabola is y = -1
From, the focus
k + p = 1
k = 1 - p
The formula of directrix is
y = k - p (1)
Substituting the value of directrix and k
-1 = 1 -p -p
-1-1 = -2p
-2 = -2p
p = 1
Substituting the value p in equation (1)
k = 0
Now, we have got the vertex of the parabola (h ,k) is (1,0)
The equation of the parabola is
(x-h)² = 4p (y - k)
(x - 1)² = 4 (1) (y - 0)
( x -1 )² = 4(y )
