Determine the domain on which the following function is increasing. Will give brainlist if correct

Mathematics
1 answer:
grigory [225]3 years ago
8 0

Answer: D : x ∈ (1, ∞)

Step-by-step explanation:

for a function  y = f(x)

The range is the set of possible values of y.

The domain is the set of the possible values of x.

We want to find the domain on which the function is increasing.

A function is increasing if, reading from left to right, the "y" value of the function increases (or the graph goes upward)

Then we need to see on which point the graph starts going up. We can see that this happens at the vertex of the parabola, at x = 1, and it keeps increasing infinitely.

then we can write this domain as:

D : x ∈ (1, ∞)

Between which two integers does √11 lie? and √8 lie? Step by step explanation please​
sukhopar [10]

Answer:

2 and 4

Step-by-step explanation:

Consider a perfect square smaller than 8 and a perfect square larger than 11

That is 4 and 16, then

\sqrt{4} < \sqrt{8} and \sqrt{11} < \sqrt{16} , that is

Can someone help me on this pls? It’s urgent, so ASAP (it’s geometry)
SashulF [63]

<u>Question 2</u>

1) \overline{PR} \perp \overline{QS}, \overline{PQ} \cong \overline{PS} (given)

2) \overline{PR} \cong \overline{PR} (reflexive property)

3) \angle PRQ and \angle PRS are right angles (perpendicular lines form right angles)

4) \triangle PRQ and \triangle PRS are right triangles (a triangle with a right angle is a right triangle)

5) \triangle PRQ \cong \triangle PRS (HL)

Question 3

1) \angle C is a right angle, \overline{AC} \cong \overline{AE}, \overline{DE} \perp \overline{AB} (given)

2) \angle DEA is a right angle (perpendicular lines form right angles)

3) \triangle ACD and \triangle DAE are right triangles (a triangle with a right triangle is a right angle)

4) \overline{AD} \cong \overline{AD} (reflexive property)

5) \triangle ACD \cong \triangle AED (HL)

6) \angle CAD \cong \angle DAE (CPCTC)

7) \overline{AD} bisects \angle BAC (if a segment splits an angle into two congruent parts, it is an angle bisector)

Given the following exponential function, identify whether the change represents
mart [117]

Answer:

it is a decay, it's value drops by 4%

Step-by-step explanation:

0.96 is less than 1 so it is a decay function.

1-0.96 = 0.04 so it drops at the rate of 4%

Considerando las siguientes variables a = ancho y l = longitud, determina su valor, si se sabe que se cuenta con un rectángulo q
kogti [31]

Answer:

La longitud = 7 metros

La anchor = 10.5 metros

Step-by-step explanation:

La fórmula para el perímetro de un rectángulo es

P = 2L + 2W

L = longitud

A = ancho

P = 35 metros

se sabe que el doble de su ancho es igual a 3 veces su largo.

2A = 3L

Ancho = 3L / 2 = 1.5L

Sustituimos 1.5L por W

35 = 2 L + 2 (1.5 L)

35 = 2L + 3L

35 = 5 litros

L = 35/5

L = 7 metros

Por lo tanto, la longitud = 7 metros

Recuerda

A = 1.5 L

A = 1.5 × 7

A = 10.5 metros

La anchor = 10.5 metros
