Answer:
f(n) = -34
Step-by-step explanation:
n = 20
f(n) = -2(20) + 6
f(n)= -40 +6
f(n) = -34
Answer:
The cold length of metal rod is 435.14 cm
Step-by-step explanation:
Given as :
The percentage expansion of metal rod = 3.5%
The quantity of expansion = 15.23 cm
Let the cold length be x
So, 3. 5% of x = 15.23 cm
Or, 0.035 × x = 15.23 cm
Or, x = cm
∴ x = 435.14 cm
Hence The cold length of metal rod is 435.14 cm Answer
First find rise over run
rise 3 run 5
Then find where it crosses the x-intercept to get
y=3/5x-5
Answer:
The slope of the line is -5/4
Step-by-step explanation:
19) = Solution :-
5x+4y = 20
Let's keep x's value 0,
so
we get,
5x+4y = 20
or, 5×0+4y = 20
or, 4y = 20
so, y = 5
one coordinate we get (0,5)
Again
Let's keep x's value 4,
we get,
5x+4y = 20
or, 5×4+4y = 20
or, 20+4y=20
or, 4y = 0
so, y = 0
Another coordinate, we get (4,0)
now
slope(m) = (y2-y1)/(x2-x1)
= (0-5)/(4-0)
= -5/4
Answer:
The height would be 15 cm.
Step-by-step explanation:
In order to find this, we need to use the formula for the area of a parallelogram.
A = b * h
Now input known values
285 = 19 * h
15 = h
