Answer:

A root or zero of a function is a number that, when plugged in for the variable, makes the function equal to zero. Thus, the roots of a polynomial P ( x ) are values of x such that P ( x ) = 0 . The Rational Zeros Theorem

The aircraft A330 flies at an average speed of 400 miles per hchor. The expression, 400t gives the distance traveled by the airc

Olenka [21]

The expression:

$d(t)=400t$

gives the distance traveled by the aircraft in t hours, so, for t = 6:

$\begin{gathered} t=6 \\ d(6)=400(6) \\ d(6)=\frac{2400mi}{h} \end{gathered}$

Identify the equation of the line perpendicular to 9x - 3y = 18.

sweet [91]

Answer:

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

The exemplar equation has slope

9x - 3y = 18

- 3y = -9x + 18

y = 3x - 6

m = 3

so perpendicular slope will be -1/3

D has such a slope

3y = -x + 1

y = (-1/3)x + 1/3

HELP PLEASE <br> solve the right triangle

aleksandrvk [35]

Answer:

Part 1) $FG=4.4\ units$

Part 2) $EF=3.9\ units$

Part 3) $m\angle G=63^o$

Step-by-step explanation:

step 1

Find the measure of length side FG

In the right triangle EFG

we know that

$sin(27^o)=\frac{GE}{FG}$ ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

$sin(27^o)=\frac{2}{FG}$

$FG=\frac{2}{sin(27^o)}=4.4\ units$

step 2

Find the measure of length side EF

In the right triangle EFG

we know that

$cos(27^o)=\frac{EF}{FG}$ ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

$cos(27^o)=\frac{EF}{4.4}$

$EF=cos(27^o)(4.4)=3.9\ units$

step 3

Find the measure of angle G

we know that

$m\angle G+27^o=90^o$ ---> by complementary angles in a right triangle

$m\angle G=90^o-27^o=63^o$
