Answer:
y = 36
Step-by-step explanation:
y = ax²
100 = a (5)² → 100 = 25a → a = 4
y = 4x²
x = 3 → y = 4(3)² = 36
Answer
Distance= root of (x1-x2)^2+(y1-y2)^2
X1=664
X2=901
Y1=22
Y2=-138
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
lets use a significance level of = 0.1
<u> Determine if the sequence indicates randomness </u>
First step :
H0 : pattern is random
H1 : pattern not random
n1 ( number of true answers ) = 10
n2 ( number of false answers ) = 10
also number of runs for T = 5
number of runs for F = 5
Total number of runs = 5+ 5 = 10
Given that critical value at 0.05 = 23
we will reject the null hypothesis ( i.e the sequence departs from randomness )
Take f"(x)=0 to find critical values v1,v2,...
take f (vn)
produces inflection points
First you find the square and the are of the square would be 7*4=28.
then you move on to the triangles the purple ones together are 7 * 5 = 35 , since there’s 2 you don’t have to divide the area by 2 just use it as the combined for both
then black same thing 4*3 = 12
so
12+35+28=75
