The formula of pi rs represents the formula to find the lateral surface area of a right cone.
Y=ln(ln(x))
y'=(1/x)/Ln(x)=1/xln(x)
Answer:
75
Step-by-step explanation:
Homework mean x 10%: (80+100+90)/3 x 0.1 = 90 x 0.1 = 9
Quiz mean x 25%: (84+90+72)/3 x 0.25 = 20.5
Test mean x 45%: (64+72)/2 x 0.45 = 30.6
Sum of means/percentage of grade: 9 + 20.5 + 30.6 = 60.1/.8 = 75.125
Um, there are no choices, so I'll just tell you were it'd be located
Since 0.2 isn't yet 1, but its value is more than 0, it would be located in the middle of 1 and 0.
Answer:
D) 0 = 2(x + 5)(x + 3)
Step-by-step explanation:
Which of the following quadratic equations has no solution?
We have to solve the Quadratic equation for all the options in other to get a positive value as a solution for x.
A) 0 = −2(x − 5)2 + 3
0 = -2(x - 5) × 5
0 = (-2x + 10) × 5
0 = -10x + 50
10x = 50
x = 50/10
x = 5
Option A has a solution of 5
B) 0 = −2(x − 5)(x + 3)
Take each of the factors and equate them to zero
-2 = 0
= 0
x - 5 = 0
x = 5
x + 3 = 0
x = -3
Option B has a solution by one of its factors as a positive value of 5
C) 0 = 2(x − 5)2 + 3
0 = 2(x - 5) × 5
0 = (2x -10) × 5
0 = 10x -50
-10x = -50
x = -50/-10
x = 5
Option C has a solution of 5
D) 0 = 2(x + 5)(x + 3)
Take each of the factors and equate to zero
0 = 2
= 0
x + 5 = 0
x = -5
x + 3 = 0
x = -3
For option D, all the values of x are 0, or negative values of -5 and -3.
Therefore the Quadratic Equation for option D has no solution.
