Answer:
r = 11.4 cm
Step-by-step explanation:
The question says that, "Spray will make a circle with a diameter of 22.8 cm how long a radius will measure."
Given that,
The diameter of the circle, d = 22.8 cm
We know that the relation between the diameter and the circle is given by :
d = 2r
Where
r is the radius of the circle
r = d/2
r = 22.8/2
r = 11.4 cm
So, the radius of the circle is equal to 11.4 cm.
Answer:
D) 35x³ - 16x² + 44x - 48
Step-by-step explanation:
(5x2 + 2x + 8)(7x – 6) = (5x2 + 2x + 8)* 7x + (5x2 + 2x + 8)*(– 6)
= (5x2*7x + 2x*7x + 8*7x) + (5x2*(-6) + 2x*(-6) + 8*(-6) )
=35x³ + 14x² + 56x - 30x² - 12x - 48
= 35x³ - 16x² + 44x - 48
The slope, or gradient, of the line is 6/-3 which is -2. The gradient is -2.
Dat is 4th degree because x is raised to the 4th power and that is the highest power of the placholder
4th degree
