The value of f(5) is $f(5)=-5$

Step-by-step explanation:

The function is $f(x)=-2x+5$

To find $f(5)$ substitute $x=5$ in $f(x)=-2x+5$

$f(5)=-2(5)+5$

Multiplying the terms, we get,

$f(5)=-10+5$

Adding the terms, we get,

$f(5)=-5$

Thus, the value of $f(5)$ is $f(5)=-5$

Which answer best describes the complex zeros of the polynomial function?

marysya [2.9K]

Answer-

D. The function has one real zero and two nonreal zeros. The graph of the function intersects the x-axis at exactly one location.

Solution-

The given polynomial is,

$f(x)=x^3-x^2+6x-6$

The zeros of the polynomials are,

$\Rightarrow f(x)=0$

$\Rightarrow x^3-x^2+6x-6=0$

$\Rightarrow x^2(x-1)+6(x-1)=0$

$\Rightarrow (x^2+6)(x-1)=0$

$\Rightarrow (x^2+6)=0,(x-1)=0$

$\Rightarrow x=\sqrt{-6},\ x=1$

$\Rightarrow x=1,\ \pm \sqrt6i$

Therefore, this function has only one real zero i.e 1 and two nonreal zeros i.e ±√6i . The graph of the function intersects the x-axis at exactly one location i.e at x = 1

Which equation is the equation of the line, in point-slope form, that has a slope of 2 and passes through the point (-8, 1)?

lutik1710 [3]

Answer:

y=2x+17

Step-by-step explanation:

y-y1=m(x-x1)

y-1=2(x-(-8))

y-1=2(x+8)

y=2x+16+1

y=2x+17

The function g(x) represents f(x)=9 cos (x-pi/2)+3 after translating pi/6 units left and 4 units up. which equation represents g

shtirl [24]

Answer:

g(x)= 9 cos (x - $\frac{\pi}{3}$ ) +7

Step-by-step explanation:

What is given is f(x) = g cos (x - pi/2) + 3

Note that the standard form of cosine function is a cos (bx + c) + d

a= amplitude

-c/b = phase shift

d = vertical shift

After moving pi/6 to the left --

x = pi/2 - pi/6 = pi/3

once moving pi/6 left, it is at pi/3

moving 4 units up just means adding 4 + 3, and that equals 7, that would be the vertical shift once applied.

So the equation that represents g(x) is C. 9 cos (x - pi/3) + 7

ELEN [110]

Answer:

A. The submarine was 217 feet below sea level after 7 minutes

Step-by-step explanation:

-350+19(7)

-350+133

-217

Since the answer is negative, the submarine was bellow sea level.
