Answer:
First option on the list:
Step-by-step explanation:
Use the distributive property of exponents to get rid of parentheses in the algebraic expression, evaluate the powers of the numerical factors, and finally, cancel common factors in numerator and denominator to arrive at the final answer:
B. 39388.16 cubic meters
C. 10257.33 cubic meters
D. 41029.33 cubic meters
Answer: A. 9847.04 cubic meters
Step-by-step explanation:
From the given picture, we have
The diameter of the cone = 28 m
Then the radius of the cone =
Height of the cone = 48 inches
The volume of cone is given by :-
Hence, the volume of the cone =
Answer:
Step-by-step explanation:
Radius
= 28 ÷ 2
= 14 m
Volume
= 1/3 (3.14) (14)²(48)
= 1/3 (3.14) (196)(48)
= 9847.04 m³
Answer:
f(x)=6x+15
Step-by-step explanation:
first you find the gradient of the equation with the gradient formula by using the two given points
the gradient is 6, so using the slope equation which is y=mx+b sub 6 into the gradient
you then get y=6x+b
to find b just sub in any of the points and solve the equation.
ps. f(x) essentially stands for a y so don't get confused
hope this helps :)
Answer:
y = 6x + 15.
Step-by-step explanation:
The slope of the line joining these 2 points =
(9-3)/(-1-(-2))
= 6/1
= 6
Use the point-slope form of a straight line:
y - y1 =m(x - x1) Here m = 6 and (x1, y1) will be (-2, 3), so:
y - 3 = 6(x -(-2))
y - 3 = 6(x + 2)
y = 6x + 12 + 3
y = 6x + 15.
You could have a Quadratic with 2 distinct solution meaning you have 2 different X intercepts
2 roots means the discriminan is positive in other words
D>0
When the discriminan is 0, D=0 we have exactly one x-intercept.
Discriminan D=0
and finally, if the discriminan were negative
D=0
then there is no solution or root at all.
