Solve the following quadratic equation: x^2-10x+25=51
please show steps i don’t understand
1. Simplify the quadratic equation into its standard form
Formula : ax^2+bx+c=0
Subtract from both sides:
x^2-10x+25=51
x^2-10x+25-51=0
x^2-10x-26=0
Use the standard form, ax^2+bx+c=0, to find the coefficients of our equation.
x^2-10x-26=0
a=1
b=-10
c=-26
The quadratic formula gives us the roots for ax^2+bx+c=0, in which a, b and c are numbers (or coefficients), as follows :
x=(-b±sqrt(b^2-4ac))/(2a)
to get the result :
x=(10±sqrt(204))/2
Simplify 204 by finding its prime factors:
The prime factorization of 204 is 2^2*3*17
x_2=-2.141
Answer:
x = 5 ± √51
Step-by-step explanation:
x² - 10x + 25 = 51
x² - 10x + 25 - 51 = 51 - 51
x² - 10x - 26 = 0
Factors with a product of -26 and a sum of -10:
NONE! Solve by completing the square (see attachment)
Step 1: Rearrange
x² - 10x + 25 = 51
x² - 10x = 26
Step 2: Add (b/2)² to both sides
x² - 10x + (-10/2)² = 26 + (-10/2)²
x² - 10x + 25 = 51
Step 3: Factor and solve
(x - 5)² = 51
x - 5 = √51
x = 5 ± √51

Suppose that y is inversely proportional to the 4th power of x, and that y=16 when x=6. What is y when x=3? Round your answer to two decimal places if necessary.
Answer:
y = 1
Step-by-step explanation:
Given
y ∝ x⁴⇒ y = kx⁴
Finding the proportionality constant, k
y = 16 and x = 316 = k (6)⁴16 = 1296kk = 16/1296k = 1/81Finding y

Answer:
f(x) = 2 -2^x
Step-by-step explanation:
The graph has a horizontal asymptote at y = 2. It has a slope that doubles in each unit interval. This tells you it is an exponential function with a base of 2, and a vertical translation of 2. The curve downward, rather than upward, means the function has been reflected across a horizontal line.
__
vertical shiftAn exponential function of the form ...
y = a·b^x
will have a horizontal asymptote at y=0. The asymptote here is y=2, so 2 has been added to the function value.
base valueThe slope of the above function (y=a·b^x) will be multiplied by a factor of 'b' when x increases by 1. Your graph has a slope (rise/run) of -1 for x between 0 and 1, a slope of -2 for x between 1 and 2, and a slope of -4 between x=2 and 3. This behavior indicates that b=-2/-1 = -4/-2 = 2.
scale factorThe function so far looks like ...
y = a·2^x +2
Using x=0, we can find the value of 'a'.
1 = a·2^0 +2
-1 = a . . . . . . . . subtract 2
Then the function is ...
f(x) = -2^x +2

Frenza is planning an $160,000 expansion to launch a new product line. Frenza currently earns $100,000 in net income, and the new product line will yield $50,000 in additional income before any interest expense. Frenza has three options: (1) do not expand, (2) expand and issue $160,000 in debt that requires payments of 8% annual interest, or (3) expand and raise $160,000 from equity financing. For each option 1, 2, and 3, compute (a) net income and (b) return on equity (Net income ÷ Equity). Ignore any income tax effects. (Round "Return on equity" to 1 decimal place.) Show less 1 2 3 Don’t Expand Debt Financing Equity Financing Income before interest expense $92,000 Interest expense 0 12,800 0 Net income $100,000 Equity $400,000 $400,000 Return on equity % % %
Based on the current income to Frenza, and the proposed expansion amount, the net income and return on equity for the three options are:
Don't Expand:
Net income = $100,000.Return on equity = 25%.Debt financing:
Net income = $137,200.Return on equity = 34.3%.Equity financing:
Net income = $150,000.Return on equity = 26.8%.What happens if Frenza doesn't expand?Net income will remain at $100,000.
Return on equity would be:
= Net income / Equity
= 100,000 / 400,000
= 25%
What happens if Frenza uses debt financing?Income goes to $150,000.
Net income:
= Income - interest
= 150,000 - (8% x 160,000)
= $137,200
Return on equity:
= 137,200 / 400,000
= $34.3%.
What happens if Frenza uses equity financing?Income goes to $150,000.
No interest payment so net income is $150,000.
Return on equity:
= 150,000 / (400,000 + 150,000 new equity)
= 26.8%

Step-by-step explanation:
<1 = 180°-102° = 78° (the extended angle is 180°)
<2 = <5 = 58°
<3 = 180° - 78° - 58° = 44° (the sum of the angles inside of a triangle is 180°)
<4 = 180° - 44° - 58° = 78° = <1 (the extended angle is 180°)

Answer:Matt’s is 40cm^3 and Mindy’s is 40in^3
Step-by-step explanation:5x2x4=40units^3
Answer:volume of rectangular prism is = whl= 2*4*5=40 unit³
the prism of the matt built will have the volume of 40cm³
where as Mindy will have 40in³
therefore,

Answer:
60%
Step-by-step explanation:

Given:
value = 24 votesTotal value = 40 membersSubstituting these into the formula:
[tex]\implies \sf \left(\dfrac{24}{40}\right) \times 100=0.6 \times 100 = 60 \%[/tex]
