Answer:

1.49598 x 10^8 kilometers.

Step-by-step explanation:

There are quite a few rules for scientific notation.

First, the number in front of the decimal cannot be larger than 9.

Second, the base should always be 10.

Furthermore, the exponent tells you how many places to move the exponent. If the exponent is negative, move the decimal to the left. If the exponent is positive, move the decimal to the right.

Lastly, the exponent may be positive or negative.

There are more rules, of course, but these should mostly help you.

Which point slope form passes through the point (-2 , -1) and has slope 5?

Sladkaya [172]

The equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)

given
slope=5
and passes throught (-2,-1) is
-2=x1
-1=y1

y-(-1)=5(x-(-2))
y+1=5(x+2)

Triangle QRS has vertices Q(-4,2),R(3,0), and S(4,3).

Dafna1 [17]

The coordinates of the vertices of $\triangle Q'R'S'$ are $Q'(x,y) = (0, -4)$ , $R'(x,y) = (7,-6)$ and $S'(x,y) = (8, -3)$ , respectively.

Vectorially speaking, a point is translated to another location on Cartesian plane by means of this expression:

$A'(x,y) = A(x,y) + T(x,y)$ (1)

Where:

$A(x,y)$ - Original point.
$A'(x,y)$ - Translated point.
$T(x,y)$ - Translation vector.

If we know that $Q(x,y) = (-4,2)$ , $R(x,y) = (3,0)$ , $S(x,y) = (4, 3)$ and $R'(x,y) = (7, -6)$ $T(x,y) = (4, -6)$ , then the coordinates of the vertices of the triangle $Q'R'S'$ are:

$Q'(x,y) = Q(x,y) + T(x,y)$

$Q'(x,y) = (-4,2) + (4,-6)$

$Q'(x,y) = (0, -4)$

$R'(x,y) = R(x,y) + T(x,y)$

$R'(x,y) = (3,0) +(4,-6)$

$R'(x,y) = (7,-6)$

$S'(x,y) = S(x,y) + T(x,y)$

$S'(x,y) = (4, 3) + (4, -6)$

$S'(x,y) = (8, -3)$

The coordinates of the vertices of $\triangle Q'R'S'$ are $Q'(x,y) = (0, -4)$ , $R'(x,y) = (7,-6)$ and $S'(x,y) = (8, -3)$ , respectively.

A polygon has 11 sides. What is the sum of the measure of the interior angles of the polygon? 1800° 1620° 1440° 1980°

dolphi86 [110]

Answer:

1620°

Step-by-step explanation:

The formula for finding that measure is ...

sum of interior angles of n-sided convex polygon = 180°×(n -2)

For n=11, this is

sum = 180°×9 = 1620°

_____

Another way to get there is to remember that the sum of <em>exterior</em> angles is always 360° for a convex polygon. Then the total (interior + exterior) of the angles of an n-sided polygon is 180°×n. Subtracting the sum of exterior angles gives the total of interior angles: 180°×n -360° = 180°×(n -2).
