Given that f(x) = x2 + 1 and g(x) = -3, multiply the functions (gºf)(x).

stich3 [128]

Answer:

$(g\cdot f) = -3x^2-3$

Step-by-step explanation:

$f(x) = x^2 + 1$

$g(x) = -3$

The problem state to multiply the function $f$ and $g$ so the symbol seems to be incorrect.

We actually want to calculate

$g(x) f(x) =gf(x) = (-3) \cdot (x^2+1)= -3x^2-3$

Note

$g\circ f(x)=g(f(x))=g(x^2+1)=-3$

Theo is using this spinner to predict the favorite movie genre of randomly chosen students in his school. If Theo spins the spin

marusya05 [52]

Answer:

Option B.

Step-by-step explanation:

In the question the number categories on the spinner are not given.

Consider there are 5 different categories on the spinner.

A = Spinner land on "Action".

So, probability of land on "Action" is

$P(A)=\frac{1}{5}$

Number of spins, n= 60 times

The expected number of land on "Action" is

$\text{Expected value}=n\times P(A)$

$\text{Expected value}=60\times \frac{1}{5}$

$\text{Expected value}=12$

Therefore, the correct option is B.

Which equation represents the line that passes through the points (–3, 7) and (9, –1)?

Harlamova29_29 [7]

Answer:

1st option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 3, 7) and (x₂, y₂ ) = (9, - 1)

m = $\frac{-1-7}{9-(-3)}$ = $\frac{-8}{9+3}$ = $\frac{-8}{12}$ = - $\frac{2}{3}$ , then

y = - $\frac{2}{3}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (9, - 1 ) , then

- 1 = - 6 + c ⇒ c = - 1 + 6 = 5

y = - $\frac{2}{3}$ x + 5 ← equation of line
