Answer:

Okay I might not be right on this one but, I believe you divide 27 and 3. As to the part about simplifying, you might want to give me so details.

50 POINTS!!! <br> Which function is shown on the graph below?<br> See photo

Volgvan

Answer:

C. $y=\sqrt{2x-6}+1$

Step-by-step explanation:

From the graph of the function, we can see that the domain of the function is $x\ge 3,$ the range of the function is $y\ge 1.$

Consider the parent function $y=\sqrt{x}.$

The domain of this function is $x\ge 0,$ the range of this function is $y\ge 0.$

The function $y=\sqrt{2x-6}+1$ has

the domain

$2x-6\ge 0\\ \\2x\ge 6\\ \\x\ge 3$

and the range

$y\ge 0+1\\ \\y\ge 1$

All other options have different domain, or the range, or both the domain and the range.

The first painter can finish a paint job in 2 hours. The second painter can finish the same job in 8 hours. How long would it ta

vampirchik [111]

Answer: $1\frac{3}{5}$ hrs

<u>Step-by-step explanation:</u>

1st painter: $\frac{1}{2}$

2nd painter: $\frac{1}{8}$

1st + 2nd = Together

$\frac{1}{2}$ + $\frac{1}{8}$ = $\frac{1}{x}$

$\frac{1}{2}(8x)$ + $\frac{1}{8}(8x)$ = $\frac{1}{x}(8x)$

4x + x = 8

5x = 8

x = $\frac{8}{5}$

= $1\frac{3}{5}$

Answer:

1)

Given the triangle RST with Coordinates R(2,1), S(2, -2) and T(-1 , -2).

A dilation is a transformation which produces an image that is the same shape as original one, but is different size.

Since, the scale factor $\frac{5}{3}$ is greater than 1, the image is enlargement or a stretch.

Now, draw the dilation image of the triangle RST with center (2,-2) and scale factor $\frac{5}{3}$

Since, the center of dilation at S(2,-2) is not at the origin, so the point S and its image $S{}'$ are same.

Now, the distances from the center of the dilation at point S to the other points R and T.

The dilation image will be $\frac{5}{3}$ of each of these distances,

$SR=3$ , so $S{}'R{}'$ =5 ;

$ST=3$ , so $S{}'T{}'=5$

Now, draw the image of RST i.e R'S'T'

Since, $RT=3\sqrt{2}$ [By using hypotenuse of right angle triangle] and $R{}'T{}'=5\sqrt{2}$ .

2)

(a)

Disagree with the given statement.

Side Angle Side postulate (SAS) states that:

If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle then these two triangles are congruent.

Given: B is the midpoint of $\overline{AC}$ i.e $\overline{AB}\cong \overline{BC}$

In the triangle ABD and triangle CBD, we have

$\overline{AB}\cong \overline{BC}$ (SIDE) [Given]

$\overline{BD}\cong \overline{BD}$ (SIDE) [Reflexive post]

Since, there is no included angle in these triangles.

∴ $\Delta ABD$ is not congruent to $\Delta CBD$ .

Therefore, these triangles does not follow the SAS congruence postulates.

(b)

SSS(SIDE-SIDE-SIDE) states that if three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

Since it is also given that $\overline{AD}\cong \overline{CD}$ .
