Yes.
They both will end with the equation
.. y = -2x +9
<span>$y=ax^3+bx^2+cx+d$ y = a x 3+ b x 2+ c x + d .</span>
Answer:
94
Step By Step Explanation:
6X8=48
5X7=35
1X3=3
2X4=8
48+35+3+8= 94
48+35=83
3+8=11
83+11=94
94
Answer:
cost = 1296 × 2 = $2592
Step-by-step explanation:
The concrete is likely a rectangular prism base on it dimension . The width, length and height is known. The volume of the prism should be calculated since the concrete prize is known base on it volume.
volume of a rectangular prism = Lwh
where
L = length
w = width
h = height
volume = Lwh
volume = 18 × 18 × 4
volume = 1296 ft³.
The cost of the concrete is $2 per cubic ft. Therefore, the volume for 1296 ft³ can be calculated below
$2 is the cost for 1 cubic fit
how much for 1296 cubic ft
cross multiply
cost = 1296 × 2 = $2592
The formula for calculating the height is h = 3V/πr²
<h3>Subject of the formula</h3>
The formula given is the formula for calculating the volume of a cone
V = 1/3πr²h
where
h is the height
r is the radius
Make h the subject of the formula
Cross multiply
3V = πr²h
Divide both sides by πr²
3V/πr² = πr²h/πr²
h = 3V/πr²
Hence the formula for calculating the height is h = 3V/πr²
