Answer:

(g+5)²(g-3)

Step-by-step explanation:

we just need the denominator so we can ignore everything on top

with that in mind mulitply the denominators to find the LCD

(g²+2g-15)(g+5)=g³+7g²-5g-75

Factor this (i used synethic divison, can explain if needed)

(g+5)²(g-3)

What is the relation between the trigonometric ratios tan(R) and tan(J)? Please answer ASAP!
Ilya [14]

Step-by-step explanation:

∆PQR similar to ∆ JKL

JK/KL= PQ/QR

6/12=3/QR

QR=3×2= 6

therefore, tan(R) = PQ/QR = 3/6=1/2

and, tan(J) = KL/JK =12/6=2

\frac{ \tan(R) }{ \tan(J) }  =  \frac{ \frac{1}{2} }{2}

\frac{ \tan(R) }{ \tan(J) }   =  \frac{1}{4}

tan(J)=4.tan(R)

option D

Last autumn, julia noticed something interesting as she blew up spherical balloons for harris's birthday party. she calculated t
Vikki [24]
To find whether the volume would be doubled when the radius is,we can find the volume of the two balloons.

The formula of a sphere is:
\frac{4}{3} \pi \: {r}^{3}
Let's take 丌 as 3.14

The volume of the balloon with 4cm radius:
\frac{4}{3}(3.14)  \times  {4}^{3}  \\  = 4.18667 \times 64 \\  = 267.94688

The volume of the balloon with 8cm radius:
\frac{4}{3}(3.14)  \times  {8}^{3}  \\  = 4.18667 \times 512 \\  = 2143.57504
As we can see,
267.94668 × 2 = 535.89 ≠2145.56

Thus,she wouldn't discover that the volume is twice as big when the radius is doubled.

Hope it helps!

Order the following numbers written in scientific notation from greatest to least: 3.9 × 105, 6.1 × 103, 9.3 × 105, 1.6 × 103 A.
Licemer1 [7]

The numbers are:

3.9 × 105 = 409.5

6.1 ×103 = 628.3

9.3 × 105 = 976.5

1.6 × 103 = 164.8

Arranging from greatest to least and in scientific notation form gives:

9.3 × 105 , 6.1 × 103 , 3.9 × 105 , 1.6 × 103

*(Seems like there is no correct answer from the choices given there).
