Answer:

The answer to number one is 11√17

The answer to number two is 4

Step-by-step explanation:

In number one: once you get both radicands to be equal, then you can add them. Like of it like 3x+2x. The x’s are like terms, so you can add them together.

In number two: the √5 on the top and bottom cancel out. This leaves 12/3 which is equal to 4.

Rob is travelling at a constant speed in a car. He travels 105km in 1 hour and 30 minutes. The speed limit is 80km/h. Is Rob tra

abruzzese [7]

Answer:

Yes.

Step-by-step explanation:

Let's first convert his speed to km/h.

$\frac{105km}{1.5h} = 70\frac{km}{h}$ > $80\frac{km}{h}$ . Therefore, Rob is traveling within the speed limit.

Given f(x) = log2x, which of the functions below represents g(x) resulting from reflecting the graph of f(x) in the x-axis and s

enot [183]

Answer:

$g(x) = log(2x+2)$

Step-by-step explanation:

The question has missing options ; However, the question is still solvable

Given

$f(x) = log2x$

Direction = 2 units left

Required

Shift the function by 2 units in the x axis

The general format of shifting a function along the x axis (by the left) is as follows

$g(x) = log(ax+c)$

Where c represents the direction;

$c = 2$

Since $f(x) = log2x$ , then

$g(x) = log(2x+2)$

What is the distance in the standard (x, y) coordinate plane between the points (2,3) and (5,5)?

Naddik [55]

<h3>The distance between the points (2,3) and (5,5) is 3.6 units</h3>

Solution:

Distance between two points is given by:

$d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$

We have to find the distance in the standard (x, y) coordinate plane between the points (2,3) and (5,5)

From given,

$(x_1, y_1) = (2, 3)\\\\(x_2, y_2) = (5, 5)$

Substituting the values we get,

$d = \sqrt{(5-2)^2 + (5-3)^2}\\\\Simplify\\\\d = \sqrt{3^2 + 2^2}\\\\d = \sqrt{9+4}\\\\d = \sqrt{13}\\\\In\ decimal\ form\\\\d = 3.605 \approx 3.6$

Thus distance between the points (2,3) and (5,5) is 3.6 units
