a diameter perpendicular to a chord bisects the chord and its arc.
The value for the expression -10r + 9r is -1r.
A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
-10r+9r
Now, perform operations to solve
=-10 r + 9r
= r( -10 + 9)
Using properties of integers
(-) x (+ )= -
So,
= r( -1)
= -1r

Answer:
-1r
Step-by-step explanation:
The domain of the function is the set of all values x such that x is greater than or equal to one-quarter.
The range of the function is all real numbers.
The vertex of the function is (one-quarter, negative 6 and one-eighth).
The function has two x-intercepts.
The function is increasing over the interval (negative 6 and one-eighth, ∞).
The statements true about the the function f(x) = 2x2 – x – 6 are-
The vertex of parabola is the point at the intersection of parabola and its line of symmetry.
Now the given function is,
f(x) = 2x^2 – x – 6
Also, it is given that the vertex is located at (0.25, -6) and the parabola opens up, the function has two x-intercepts.
Comparing the given function with standard form,
f(x) = a x^2 bx + c
By comprison we get,
a = 2
b = -1
c = -6
Now, x-coordinate of vertex is given as,
x = -b/2a
put the values we get,
x = -(-1)/2*2
or, x = 1/4
Put the value of x in given function, so y-coordinate of the vertex is given as,
f(1/4) = 2(1/4)² - 1/4 - 6
= -49/6
= -6 1/8
Hence, The statements true about the the function f(x) = 2x2 – x – 6 are-

Answer:
The vertex of the function is (one-quarter, negative 6 and one-eighth).
The function has two x-intercepts.

The answer above is correct.
The statistical question could be How much time do people spend in the water park.
Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Hours Spent at Water Park
Hours Tally
4 4
5 5
6 3
7 4
These data could be the results of a survey whose target was to determine how many hours people spent at a water park.
The size of the sample should be the number of tally, which is 4 + 5 + 3 + 4 = 16.
And the question most likely was made at the exit of a water park, when the people were leaving the park.
Thus, the statistical question could be How much time do people spend in the water park?
It is a statistical because the survey is made to a sample of the people who went to the water park instead to all the people.
Hence, the statistical question could be How much time do people spend in the water park?

Answer:
sample responce: How many hours did you spend at the water park today?” It is statistical because the responses will vary among individuals and the responses will be numeric
Step-by-step explanation:
Answer:
The sample size is
Step-by-step explanation:
From the question we are told that
The margin of error is
The standard deviation is
From the question we are told the confidence level is 94% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the sample size is mathematically represented as

The ratio of square feet to gallons of paint:
This can also be written as:
This fraction can be simplified by dividing the numerator and denominator by 6:
So, the ratio of square feet to gallons of paint is:
1 gallon for every 240 ft².
