Solve for x. Enter the solutions from least to greatest. Round to two decimal places. (x-6)^2-5=0 lesser x= , greater x=
Answer: lesser x = 3.76 & greater x = 8.24
Step-by-step explanation: just took the test
For the given quadratic equation lesser x=3.765 and greater x=8.235.
The given quadratic equation is (x-6)²-5=0.
We need to find the solutions from least to greatest.
What is the formula to find the solution to the quadratic equation?The formula to find the solution to the quadratic equation is [tex]x=\frac{-b\pm\sqrt{b^{2}-4ac }}{2a}[/tex].
Now, (x-6)²-5=0 can be written as x²-12x+31=0
Here, a=1, b=-12 and c=31
x=(12±√20)/2
⇒x=(12±4.47)/2
⇒x=3.765 or x=8.235
Therefore, lesser x=3.765 and greater x=8.235.

Which of the equations are true identities? A. N ( n − 2 ) ( n + 2 ) = n 3 − 4 n B. ( x + 1 ) 2 − 2 x + y 2 = x 2 + y 2 + 1
Answer:
Both A and B are true identities
Step-by-step explanation:
A. N ( n − 2 ) ( n + 2 ) = n 3 − 4 n
We need to show that (left-hand-side)L.H.S = R.H.S (right-hand-side)
So,
n ( n − 2 ) ( n + 2 ) = n(n² - 2²) (difference of two squares)
= n³ - 2²n (expanding the brackets)
= n³ - 4n (simplifying)
So, L.H.S = R.H.S
B. ( x + 1 )² − 2x + y² = x² + y² + 1
We need to show that (left-hand-side)L.H.S = R.H.S (right-hand-side)
So,
( x + 1 )² − 2x + y² = x² + 2x + 1 - 2x + y² (expanding the brackets)
= x² + 2x - 2x + 1 + y² (collecting like terms)
= x² + 1 + y²
= x² + y² + 1 (re-arranging)
So, L.H.S = R.H.S
So, both A and B are true identities since we have been able to show that L.H.S = R.H.S in both situations.

A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
Answer:
47378.31625 Liters
Step-by-step explanation:
A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
From the above question,
1 gallon = 3.79 Liters
12500 7/8 gallons = x Liters
Cross Multiply
x Liters = 12500 7/8 × 3.79 Liters
x = 47378.31625 Liters
Therefore, the number of liters of water in the fountain is 47378.31625 Liters

A. -6
B. -0.7
C.0.4
D.3
The value of "a" for a narrow graph will be equal to 7.
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
GIven functions are:-
f(x) = ax²
f(x) = 7
At the value of a=7 the graph of function f(x) = 7x² opens upward and is narrower than the graph of f(x) = x².
Hence the value of "a" for a narrow graph will be equal to 7.

First three terms of a sequence is shown below. Determine if the sequence is geometric. If so, state the common ratio.
30, 10, 103, ...
a.The sequence is geometric, and the common ratio is 13.
b.The sequence is geometric, and the common ratio is 3.
c.The sequence is geometric, and the common ratio is -20.
d.The sequence is not geometric.
Answer:
Step-by-step explanation:
The common ratio is a constant found by dividing any term by the previous term.
10/30=1/3
103/10=10.3
Since those fractions are not equal this is NOT a geometric sequence.
What is the weight (in grams) of a liquid that exactly fills a 182.8 milliliter container if the density of the liquid is 0.135 grams over milliliter? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.
The weight in grams of the liquid in the container is required.
The weight in grams of the liquid that fills the container is 24.68 grams. The calculations to find this value is shown below.
Density
V = Volume of liquid in the container = 182.8 milliliter
[tex]\rho[/tex] = Density of liquid = 0.135 grams over milliliter
The relation between volume, mass and density is given by
[tex]m=\rho V\\\Rightarrow m=0.135\times 182.8\\\Rightarrow m=24.678\approx 24.68\ \text{grams}[/tex]
