True. Polynomial means consisting of several terms. An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variables.
For example:
f(x) = x3 + 2x 1/2

Since there are two parts to this equation, it is polynomial.
I hope I helped.

Adam jogs at an average speed of 10km/h from his house to the airport. The airport is 7km away from his house. At what time must

mote1985 [20]

Answer:

6:38am

Step-by-step explanation:

From the question we are told that

Average speed $V_{avg}=10km/h$

Distance traveled $d=7km$

Generally the velocity across a distance is mathematically given given as $V=d/t$

$10=\frac{7}{t}$

$t=0.7h\\t=42minutes$

Therefore

7:20-42 minutes =6:38am

Graph g is a translation of the graph of y= sin x (dashed line).a) write down the equation of g b) write down the coordinates of

labwork [276]

Answer:

a) $G(x)= \sin x + 2$

b) The coordinates of P are

$\displaystyle \left( \frac{3\pi}{2},1\right)$

Step-by-step explanation:

Translation

The dashed line shows the graph of the function

$y = \sin x$

This function has a maximum value of 1, a minimum value of -1, and a center value of 0.

Graph G shows the same function but translated by 2 units up, thus the equation of G is:

$\boxed{G(x)= \sin x + 2}$

b) The coordinates of P correspond to the value of

$x = \frac{3\pi}{2}$

The value of G is

$\displaystyle G(\frac{3\pi}{2})= \sin \frac{3\pi}{2} + 2$

Since

$\sin \frac{3\pi}{2}=-1$

$\displaystyle G(\frac{3\pi}{2})= -1+ 2=1$

The coordinates of P are

$\displaystyle \left( \frac{3\pi}{2},1\right)$

What is the point-slope form of the equation for the line with a slope of -2 that passes through the point (4,-6)

LUCKY_DIMON [66]

Answer:

$y + 6 = -2 (x-4)$

Step-by-step explanation:

Point-slope formula is represented by the equation $y-y_1 = m (x-x_1)$ . When knowing a point a line crosses through and its slope, you can write an equation in this form. Substitute the $m$ , $x_1$ , and $y_1$ for real values.

The $m$ represents the slope of the line. Since we know the slope is -2, substitute -2 for $m$ . The $x_1$ and $y_1$ represent the x and y values of the point the line passes through. Since the line passes through (4, -6), substitute 4 for $x_1$ and -6 for $y_1$ . This gives the following answer and equation:

$y-(-6) = -2 (x - (4))\\y + 6 = -2 (x-4)$
