tigry1 [53]

Answer:

g(x) = |x/5|

Step-by-step explanation:

A function is stretched horizontally by a factor of k when x is replaced by x/k.

g(x) = f(x/5)

g(x) = |x/5| . . . . . stretch of absolute value by a factor of 5

Write an equation of a circle that has the center at the origin and goes through (-3,-6)

dexar [7]

Answer:

$x^{2} +y^{2} = 45$

Step-by-step explanation:

General Equation of circle is

$(x-x_1)^{2} +(y-y_1)^{2} = r^{2}$ ----------- (1)

Here

$(x_1, y_1)= (0, 0)$

Radius r is distance from origin (x1, y1) to point (x2, y2)=(-3, -6)

$r=\sqrt{(x_2-x_1)^{2} + (y_2-y_1)^{2} }$

$r= \sqrt{(-3-0)^{2} + (-6-0)^{2} }$

$r= \sqrt{9+36}$

$r=\sqrt{45}$

Substituting values in equation (1)

$(x-0)^{2} +(y-0)^{2} =( \sqrt{45})^{2}$

$x^{2} +y^{2} = 45$

The diameter of Mercury is approximately 4.9×103 kilometers. The diameter of Saturn is approximately 1.2×105 kilometers. About h

soldier1979 [14.2K]

As soon as you see "How many times . . .", that usually tells you that finding the answer involves division. (It certainly does in this one.)

(1.2 x 10⁵) / (4.9 x 10³) =

(1.2/4.9) x (10⁵⁻³) =

0.245 x 10² = 24.5 times

It looks like B is the closest choice.

PLZ HURRY IT'S URGENT!!

DIA [1.3K]

Answer:

42 and 63

Step-by-step explanation:

I think you mean the ratio is 2/3 instead of 23

Then the answer is 42/63 = (2 x 21) / ( 3 x 21) = 2/3
