The axis of symmetry for the graph of the function f(x) = 3x2 + bx + 4 is x = 3/2 . What is the value of b?
Answers
to find the x value of the vertex of ax^2+bx+c=0
x value=-b/2a
3x^2+bx+4=0
3/2=vertex
-b/2(3)=3/2
-b/6=3/2
times 6
-b=18/2
-b=9
times -1
b=-9
The axis of symmetry for the graph of the function f(x) = 3x2 + bx + 4 is x = 3/2. The value of b is -9.
What is a function?
The function is a type of relation, or rule, that maps one input to a specific single output.
The axis of symmetry for the graph of the function
f(x) = 3x2 + bx + 4
x = 3/2 .
In order to find the b value of the vertex of ax^2 + bx + c=0
x = -b/2a
3x^2+bx+4 = 0
Given;
3/2 = vertex
-b/2(3) = 3/2
-b/6 = 3/2
-b = 18/2
-b = 9
b=-9
Thus, The value of b is -9.

Answer:
2.4%
Step-by-step explanation:
Simple interest (I) is calculated as
I =
where P is the principal, R the rate of interest and T time in years
Here I = 96, P = 800 and T = 5, thus
96 = =
= 40R ( divide both sides by 40 )
R = = 2.4%

The total number of students who preferred apples than cherries are 70 if the two hundred students were surveyed about their favorite fruit option, fourth is correct.
What is the percentage?
It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
From the diagram, we can see the total 35% students preferred apples.
Total number of students = 200
The number of students who preferred apples than cherries = 200×35%
= 200(35/100)
= 2(35)
= 70
Thus, the total number of students who preferred apples than cherries are 70 if the two hundred students were surveyed about their favorite fruit option fourth is correct.

Answer:
The answer is 4.
Step-by-step explanation:
I believe that, if I'm correct, 2 students are equal to 1%. 2 x 35 = 70. 2 x 33 = 66. 70 - 66 = 4 more students. I hope this is correct.

To figure out how far the points are from each other, you have to use the distance formula:
D_{AB}= \sqrt{(2--1)^2+{(3-4)^2}
Now, the formula for the perimeter of a pentagon is
P = 5×side length
So...
Perimeter = 5×
The answer is (2)
the answer is (2) because using the distance formula which can be found on your browser, it will lead us to the answer 5 radical 10
