Find the standard form of the quadratic equation: f(x)=(2x-1)(x+4)

Mathematics
1 answer:
katrin [286]3 years ago
3 0

Answer:

f(x) =  2x ^{2}  + 7x  -  4

Step-by-step explanation:

\because \: f(x) = (2x - 1)(x + 4) \\  \therefore \:f(x) =  2x(x + 4)  - 1(x + 4) \\ \therefore \:f(x) =  2x ^{2}  + 8x -   x  -  4 \\ \therefore \:f(x) =  2x ^{2}  + 7x  -  4 \\

Trey deposited 20% of his paycheck in the bank. if he deposited $30 how much was his paycheck
Komok [63]

Answer: 150

Step-by-step explanation: so when you want a whole amount of something you want to the 100% of it because 100% is the whole thing right? Well right now you only have 20% so how much do you need to multiply that by to get 100%?? Well that answer is 5. Okay so now since $30 is 20% but we wanna get it to 100% multiply it by 5 so 30x5 which is 150

You can only draw one unique isosceles triangle that contains an angle of 55°?
blsea [12.9K]

-- If the 55° angle is one of the two equal angles, then
the third angle is 70° .

-- If the 55° angle is the third angle, then each of the two
equal angles is 62.5° .

-- For either of these cases, there are an infinite number
of possible sets of side-lengths.

The statement in the question does not hold water.

Solve the following problem and show the work. (x - 6)^2 + (y + 1)^2 = 40
Taya2010 [7]

Answer:

see explanation

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 6)² + (y + 1)² = 40 ← is the equation of a circle in standard form

centre = (6, - 1) and r = \sqrt{40} = 2\sqrt{10}
