Find a degree 3 polynomial P such that P(−1) = −3, P(0) =−2, P(1) = −1, and P(2) = 6.

Aleksandr-060686 [28]

Answer:

Step-by-step explanation:

let polynomial P(x)=ax³+bx²+cx+d

-3=-a+b-c+d

-2=d

-1=a+b+c+d

-1=a+b+c-2

a+b+c=1

-3=-a+b-c-2

a-b+c=1

a+b+c-(a-b+c)=1-1=0

2b=0

b=0

so a+c=1

6=8a+4b+2c+d

6=8a+4b+2c-2

8a+4b+2c=8

4a+2b+c=4

or 4a+0+c=4

4a+c=4

a+c=1

subtract

3a=3

a=1

1+c=1

c=0

The graph of g(x) resembles the graph of f(x=x)^2, but it has been changed. Which of these is the equation of g(x)?

faltersainse [42]

Answer:

A. g(x) + 3/5x^2 - 3

Step-by-step explanation:

Well we can tell that the parabola is wider than its parent function "y=x^2",

Meaning x is now a fraction or a decimal less than 1.

So we can eliminate choices B and D.

Also we can see that the y intercept is at -3 because thats where the parabola touches the y axis.

Thus,

the answer is choice A. $g(x) + \frac{3}{5} x^2 - 3$ .

Hope this helps :)

The angle of deperession of aPt A, as measured form the top of

lara [203]

Answer:B

Step-by-step explanation:

Given

Height of building $h=30\ m$

Angle of depression $\theta =45^{\circ}$

Suppose distance of Point A from base of building be $x$

From diagram we can write

$\Rightarrow \tan \theta =\dfrac{h}{x}$

$\Rightarrow \tan (45^{\circ})=\dfrac{30}{x}$

$\Rightarrow 1=\dfrac{30}{x}$

$\Rightarrow x=30\ m$

So, point A is $30\ m$ from base of building

F(r) = 3.14r2 . What is f(3)?

lbvjy [14]

Answer:

The value of f(3) = 28.26

Step-by-step explanation:

You have to do is to substitute r = 3 into the function :

$f(r) = 3.14 \times {r}^{2}$

$f(3) = 3.14 \times {3}^{2}$

$f(3) = 3.14 \times 9$

$f(3) = 28.26$
