Explain, in words, how you can identify a perfect square trinomial whose leading coefficient is 1

1 answer:

4 0

When the leading coefficient is 1,
If the constant ( c term) is a perfect square and the b term is 2* the square root of the c term.
Ex.
x*2 + 10x + 25
2*5 = 10 5*5=25
Ex.
x^2 - 12x + 36
2 * -6 = -12 6*6=36

If Cp = Rs 660, Loss percent = 5% find Sp

Aneli [31]

Answer:

SP = 627 Rs

Step-by-step explanation:

Percentage loss is calculated as

$\frac{CP-SP}{CP}$ , then

$\frac{660-SP}{660}$ = 5% = 0.05 ( multiply both sides by 660 )

660 - SP = 33 ( subtract 660 from both sides )

- SP = - 627 ( multiply both sides by - 1 )

SP = 627 Rs

A diver went 24 feet below the surface of the ocean, and then 47 feet down. What is the diver's new position relative to the sur

dmitriy555 [2]

Answer:

71 feet below the water.

Step-by-step explanation:

x=the divers position relative to the surface

when x=0, the diver is at the surface.

when x=-24, the diver is 24 feet below the surface, therefore -24-47=-71.

Find the slope between the following coordinates. (6,4)&(6,-2)

Grace [21]

Answer:

slope is undefined

Step-by-step explanation:

calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (6, 4 ) and (x₂, y₂ ) = (6, - 2 )

m = $\frac{-2-4}{6-6}$ = $\frac{-6}{0}$

division by zero is undefined, therefore the slope of the vertical line is undefined.
