One of the legs of a right triangle measures 1 cm and its hypotenuse measures 2 cm.

FromTheMoon [43]

Answer:

1.7 cm

Step-by-step explanation:

The formula to find the hypotenuse: $c^{2} = a^{2} +b^{2}$ . In this case, the hypotenus is given.

1) Substitute the values into the formula.

$2^{2} = 1^{2} +b^{2}$

2) Solve for $b$ .

$4 = 1 + b^{2} \\4 - 1 = b^{2}\\3 = b^{2}\\\sqrt{3} = b\\1.73205 = b$

3) Round the answer to the nearest tenth.

$1.7 = b$

Henry counted units to find the distance between two points. For which pair of points could he have done this ? Select all that

Flura [38]

Options:

(–3, 5) and (–2, 5) (–3, 5) and (–9, 3)

(5, 3) and (9, 3) (5, –9) and (3, –5)

(2, 3) and (7, 3)

Answer:

(–3, 5) and (–2, 5)

(5, 3) and (9, 3)

(2, 3) and (7, 3)

Step-by-step explanation:

To do this, have to compare the both x and both y coordinates of the points.

If the x coordinates are equal or the y coordinates are equal, then that option is true

For (a): (-3,5) and (-2,5)

The y coordinates are the same:

i.e.

$y_1 = y_2 = 5$

This option is true

For (b): (-3, 5) and (-9, 3)

None of the coordinates are the same;

i.e.

$x_1 \ne x_2$

$y_1 \ne y_2$

Hence, this option is false.

For (c): (5, 3) and (9, 3)

The y coordinates are the same:

i.e.

$y_1 = y_2 = 3$

This option is true

For (d): (5, -9) and (3, -5)

None of the coordinates are the same;

i.e.

$x_1 \ne x_2$

$y_1 \ne y_2$

Hence, this option is false.

(2, 3) and (7, 3)

The y coordinates are the same:

i.e.

$y_1 = y_2 = 3$

This option is true

What is the constant of the function ??

Veseljchak [2.6K]

Answer:

Step-by-step explanation:

A quadratic function is a function of the form f(x) = ax^2 +bx+c, where a, b, and c are constants and a <> 0. (a not equal to 0)

The term ax^2 is called the quadratic term (hence the name given to the function), the term bx is called the linear term, and the term c is called the constant term.
