A line has a slope of 1/4.What is a slope parallel to it?What slope is perpendicular?

2 answers:

6 0

A slope parallel to it will have the same slope. So it will be 1/4.

A perpendicular slope will have the opposite reciprocal of the given slope. So it will be -4.

Answer:

The perpendicular slope will be -4.

Step-by-step explanation:

In order to find perpendicular slope, you first need to flip the fraction. So, 1/4 becomes 4/1 or 4. Then you negate it. So, 4 becomes -4.

The end of a hose was resting on the ground, pointing up an angle. Sal measured the path of the water coming out of the hose and

Travka [436]

Answer:

3.2 feet

Step-by-step explanation:

The equation $f(x)=-0.3x^{2}+2x$ shows the height of water [ $f(x)$ ] and horizontal distance [ $x$ ].

Given the horizontal distance is 4 feet, they want to know the height.

Simply put 4 in $x$ of the equation and solve for $f(x)$ . So,

$f(x)=-0.3(4)^{2}+2(4)\\f(x)=3.2$

So, the height of the water was 3.2 feet above the ground.

How does replacing f(x) with f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative) affect

ivann1987 [24]

F(x) + k - Moves the graph k units up.

k f(x) stretches the graph parallel to y-axis by a facor k

f (kx) stretches the graph by a factor 1/k parallel to x-axis

f(x + k) moves the graph 3 units to the left.

For k negative the first one moves it k units down

for second transform negative does same transfoormation but also reflects the graph in the x axis

For the third transform negative k :- same as above but also reflects in y axis

4th transform - negative k moves graph k units to the right

Calculate the distance between each given pair of points. Round your answer to the nearest tenth, if necessary.

Ksju [112]

The answer is 5

Here are the steps:

First off, we will be using the distance formula of
$d=\sqrt{(x_ {2}- x_{2}) ^{2}+( y_{2}- y_{1})^2 }$

So we have the ordered pairs of (3,1) and (6,5)

Once you plug them into the formula it should look like this:
$d= \sqrt{(6-3)^2+(5-1)^2}$

Now we do the math inside the parenthesis and end up with:
$d=\sqrt{3^2+4^2}$

Then you multiply by the power and simplify to get:
$d=\sqrt{25}$

And the $\sqrt{25}$ =5

So your answer is 5
