Can you help me please<br>Find the distance between the points (1,1) and (7,-7)
Vera_Pavlovna [14]

Answer:

10 units

Step-by-step explanation:

to find the distance between two points you will need to use the distance formula:

\sqrt{(x1-x2)^{2}+(y1 - y2)^{2}  }

the x1 refers to the x coordinate in the first bracket, the x2 refers to the x coordinate in the second bracket, etc.

insert the coordinates into the equation:

\sqrt{(1 - 7)^{2}+(1--7)^{2}  }

a double negative equals a positive

insert this equation into your calculator:

\sqrt{(1-7)^{2}+(1+7)^{2}  } = 10

∴ the distance between the points (1,1) and (7,-7) are 10 units

I hope this was helpful :-)

Use the discriminant to describe the roots of each equation. Then select the best description.16x2 + 8x + 1 = 0double rootreal a
SSSSS [86.1K]

Hello!

The discriminant of quadratic functions is: b² - 4ac. Since the equation is in standard form, which is Ax² + Bx + C = 0 , we can substitute those values into our discriminant and simplify.

The value of the discriminant will tell us how many solutions there are to the given quadratic equation.

A positive discriminant will have two real solutions.

A discriminant of zero will have one real solution.

A negative discriminant will no real solutions.

1. Substitute, a = 16, b = 8, c = 1.

8² - 4(16)(1)

64 - 4(16)(1)

64 - 64(1)

64 - 64

0

Since the discriminant is zero, the answer is choice A, double root, because since it is raised to the power of 2, it must has two roots, but in this case, both of the roots the same x-values.
