Answer:
D) 1541
Step-by-step explanation:
I like to answer it w without deriving the formula of f(g(x)). So, we go this way, you firstly have to find g(7) which will be equal to 3 * 7 - 5 = 16.
And then you find f(16) = 6*16*16+5 = 1541. That's all.
Hello :
<span>y = –2x² +6x – 1.
y = -2(x²-3x)-1
y= -2( x² -2(3/2)x +(3/2)² - </span>(3/2)²)-1
y = -2((x-3/2)² -9/4))-1
y = -2(x-3/2)² +7/2
the <span>axis of symmetry is the line : x = 3/2 and vertex : (3/2 , 7/2 ) </span>
Answer:
Step-by-step explanation:
<u><em>Distance between two points:</em></u> Distance between two points 
is given by
1. The monomial, x, a factor of the expression x2 + 15x "represents the side length, in centimeters, of the photo." So Choice A.
2. The binomial, (x + 15), a factor of the expression x2 + 15x is Choice D because x is the length of the photo plus the 15 cm left of the frame.
3. The first-degree term of the expression x2 + 15x is the area of the photo since "x" is the length. So, Choice C.
4. The second-degree term of the expression x2 + 15x is the area of the frame around the picture. That leaves us with Choice B.
When an interaction term in a multiple regression model may be used when the relationship between X1 and Y changes for differing values of X2.
According to the question,
We have the following information:
An interaction term in a multiple regression model may be used and the four options are given.
We know that when the change of one independent variable depends on the change of another independent variable then it is considered to have an interaction.
Now, for the given expression and applying the given conditions, options a, c and d are wrong.
Hence, the correct option is b.
