What’s the slope of the line?

Mathematics

1 answer:

gtnhenbr [62]3 years ago

4 0

Answer:

Step-by-step explanation:

The line intercepts the points (-3,1) and (-3,2) so we can use these to find the slope. In order to connect the two points, we have to move down 4, and over 5. The equation for finding slope is rise over run which means the slope of this line is 4/5

What is 80 in its simplest form as a fraction?

Ann [662]

I believe the correct given problem is:

“What is 80% in its simplest form as a fraction?”

Take note that you missed to place the percent sign which is very important.

Now to solve this, 80% when converted to decimal form is 0.80 which means that you have 80 parts per 100 parts. Therefore the fraction form of this would be 80 / 100.

fraction = 80 / 100

However this fraction is not yet the answer because we can still simplify this further. First step in simplifying is to divide both the numerator and denominator by 10 so that we are left with:

8 / 10

Next step is to divide by 2:

4 / 5

Now we can see that we can no longer divide this (numbers should be whole number). Therefore the simplest form as a fraction is 4/5

Answer:

4/5

What is the perimeter of the figure in the diagram (round to three decimal places if necessary)? A) 54.5 B) 42.634 C) 39.5 D) 27

beks73 [17]

Answer:

Step-by-step explanation:

First add all the simple line up so;

$8 + 7 + 3 + 2 = 20$

Then use Pythagoras to work out the lengths of the remaining lines

$\sqrt{ {2}^{2} + {4}^{2} } = 2 \sqrt{5} \\ \sqrt{ {3}^{2} + {1}^{2} } = \sqrt{10} \\ 20 + \sqrt{10} + 2 \sqrt{5} = 27.63441362$

So to three decimal places it would be;

$27.634$

Video Example EXAMPLE 1 Find the linearization of the function f(x) = x + 1 at a = 3 and use it to approximate the numbers 3.98

Blizzard [7]

Answer:

the linearization is y = 1/4x +5/4

the linearization will produce <em>overestimates</em>

the values computed from this linearization are ...

f(3.98) ≈ 2.245

f(4.05) ≈ 2.2625

Step-by-step explanation:

Apparently, you have ...

$f(x)=\sqrt{x+1}$

from which you have correctly determined that ...

$f'(x)=\dfrac{1}{2\sqrt{x+1}}$

so that f(3) = 2 and f'(3) = 1/4. Putting these values into the point-slope form of the equation of a line, we get the linearization ...

g(x) = (1/4)(x -3) +2

g(x) = (1/4)x +5/4

The values from this linearization will be overestimates, as the curve f(x) is concave downward everywhere. The tangent (linearization) is necessarily above the curve everywhere.

At the given values, we find ...

g(3.98) = 2.245

g(4.05) = 2.2625
