help please i got absolutely no clue how to solve this
Answer:
A)
Step-by-step explanation:
To complete the square, we need to find such p and q that:
r^2 - 12r - 27 = (r - p)^2 - q = r^2 - 2pr + h^2 - q
Because we know that 2pr = 12r, then p = 6
(r - p)^2 - q = (r - 6)^2 - q = r^2 - 12r + 36 - q
We know that 36 - q = -27, so q = 36+27 = 63
Now we can solve for = 0
(r - 6)^2 - 63 = 0
(r - 6)^2 = 63
r - 6 = √63 or r - 6 = -√63
r = 6 + √63 = 6 + 3√7 or r = 6 - √63 = 6 - 3√7
A hose fills a 18-gallon tub in 3 minutes how long will it take to fill a 45 gallon tub
Answer:
your answer should be 7 or 7.5 minutes.
Step-by-step explanation:
Hope this helps and have a great day
The required time to fill the tub is 7.5 minutes.
What is Unitary method ?In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The time taken by hose to fill 18-gallon tub is 3 minutes.
So, the time taken by the the same hose to fill 45 gallon can be calculated using unitary method as,
The time it takes to fill 1 gallon is 3/18 = 1/6.
Thus, the time for filling 45 gallon is 1/6 × 45 = 7.5 minutes.
Hence, the time taken by the hose to fill 45 gallon tub is 7.5 minutes.

A die is rolled 10 times. Find the probability of rolling exactly 1 four.
Answer:
10 in 60 chance, or simplified to 1 / 6
Step-by-step explanation:
1 in 6 chance of rolling a four in one roll
Multiply both sides by 10
10 in 60
The probability of rolling exactly 1 four is [tex]1.65\times10^{-8}[/tex].
Given that, a die is rolled 10 times.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
When throwing die once, we get
Probability of getting 4 = 1/6
Now, a die is rolled 10 times
= [tex](\frac{1}{6} )^{10}[/tex]
= 1/60466176
= [tex]1.65\times10^{-8}[/tex]
Hence, the probability of rolling exactly 1 four is [tex]1.65\times10^{-8}[/tex].

Please help I’m stuck on this
Answer:
y = 1/2x +1/2
Step-by-step explanation:
I find it easier to write the equation if I can find grid intersection points where the line crosses. Here, a couple of them are (1, 1) and (3, 2).
The slope can be found from ...
m = (y2 -y1)/(x2 -x1)
m = (2 -1)/(3 -1) = 1/2
The y-intercept can be found from ...
b = y -mx
b = 1 -(1/2)(1) = 1/2 . . . . . . using (x, y) = (1, 1)
Then the slope-intercept equation is ...
y = mx +b
y = 1/2x +1/2
In standard form, the equation can be written as ...
x -2y = -1 . . . . . multiply by 2; subtract y+1 from both sides
Is y+1=5(x-9) linear or nonlinear
Answer:
It Is Nonlinear
Step-by-step explanation:
Nonlinearity is a term used in statistics to describe a situation where there is not a straight-line or direct relationship between an independent variable and a dependent variable. In a nonlinear relationship, changes in the output do not change in direct proportion to changes in any of the inputs.
