Answer:
<em>(x^2 + 4)(x^2 + 1)</em>
Step-by-step explanation:
x^4 + 5x^2 + 4 =
= (x^2 + 4)(x^2 + 1)
That's already in gradient-intercept form, EXCEPT that we typically write such an equation with y positive.
So we'd geet y = -x - 1 (answer)
Note that "gradient" means "slope" here. The slope is -1 and the y-intercept is also -1.
It's not possible to answer this question without the other information in the middle,
which you skipped as you copied the question. That information tells us the size
of the big tiles, the size of the small tiles, and the size of the room. That's how we
figure out how many tiles he needs, and once we know that, we can figure out how
much they cost. (You also skipped the cost of the big tiles. We'll need that too.)
Answer: 615.4mm cube
Step-by-step explanation:
The volume of a cylinder is given as πr^2h
where r= radius
h = height
π = 3.14
From the question, diameter is 14mm and height is 4mm.
To get the radius, we divide the diameter by 2 which will give:
= 14mm/2 = 7mm
Volume= πr^2h
= 3.14 × 7^2 × 4
= 3.14 × 49 × 4
= 615.4mm cube
The volume of the cylindrical barrel is 615.4mm cube.
