The interior angle of a triangle is the angle made by two sides of this triangle and what is the little angle made by these two sides
If you would like to know the discriminant of the quadratic equation 0 = -x^2 + 4x - 2, you can do this using the following steps:
<span>0 = -x^2 + 4x - 2
</span>
<span>0 = ax^2 + bx + c
a = -1, b = 4, c = -2
D =
b^2 - 4 * a * c = 4^2 - 4 * (-1) * (-2) = 16 - 4 * 2 = 16 - 8 = 8
</span>
The correct result would be b. 8.
Answer:
38.88
Step-by-step explanation:
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
Answer: 48% compared to 18%
<u>Step-by-step explanation:</u>
The first item to be compared is Students:
Students-Small divided by Students-Total
48 ÷ 100 = 48%
The second item to be compared is Adults:
Adults-Small divided by Adults-Total
18 ÷ 100 = 18%
Answer:
solution given a-d ,a, a+d, a+2d are in A.P
according to the question
sum of 4 terms =12
a-d+a+a+d+a+2d=12
4a+2d=12
2a+d=12/2
d=6-2a
again
3rd + 4rt term =14
a+d+a+2d=14
2a+3d=14
substituting value of d
2a+3(6-2a)=14
2a+18-6a=14
18-14=4a
a=4/4=1
again
d=6-2×1=4
first term =a-d=1-4=-3
second term =a=1
third term =a+d=1+3=4
forth term =a+2d=1+3×2=7
