Hey there!!
Given equation :
f ( x ) = x² + 2x + 1
Find f ( 2b )
In order to solve this question, we will need to replace the value 2b instead of x
... f(2b) = ( 2b )² + 2 ( 2b ) + 1
... f(2b)= 8b² + 4b + 1
Hope my answer helps!
Answer: (upside down fancy u) q5
Step-by-step explanation:
Simply apply the law of conservative (upside down fancy u)
-30-6r=36
We move all terms to the left:
-30-6r-(36)=0
We add all the numbers together, and all the variables
-6r-66=0
We move all terms containing r to the left, all other terms to the right
-6r=66
r=66/-6
r=-11
Answer:
84%
Step-by-step explanation:
Henry completed a total of 50 questions. From these 50 he predicted 36 were right and this means he also predicted that 14 were wrong (50-36 = 14). From these predictions 5 out of 36 from the ones that he predicted were right were actually wrong and 3 of the 14 questions (14-11 = 3) he predicted were wrong were actually right. Meaning in total he wrongly predicted 8 questions which means he predicted 42 correctly ...
42 / 50 = 0.84 = 84%
Therefore, Henry's prediction accuracy is 84%
