the answer is 78 kilometers.

1 cm=15 kilometers

so, 6 cm is equal to 90 kilometers.

0.8 millimetres is approximately 12 kilometers.

90 kilometers minus 78 kilometers is equal to 12.

Find the inverse of f (x) = x + 2 + 9

Brut [27]

Answer:

y = x - 11

Step-by-step explanation:

First, turn the f(x) into a y:

y = x + 2 + 9

Now, switch the x and y.

x = y + 2 + 9

Add like terms.

2 + 9 = 11

x = y + 11

Now, solve for y. Subtract 11 on both sides.

y = x - 11

What is the formula for the nth term of the given sequence 100, 20, 4, …

Naily [24]

Answer:

$a_n=100 \left(\dfrac15\right)^{n-1}$

Step-by-step explanation:

General equation of geometric sequence: $a_n=ar^{n-1}$

Given:

a₁ = 100
a₂ = 20
a₃ = 4

$\implies a_1=a=100$

$\implies a_2=100 \cdot r=20$

$\implies a_3=100 \cdot r^2=4$

Common ratio:

$r=\dfrac{a_3}{a_2}=\dfrac{4}{20}=\dfrac15$

Therefore:

$a_n=100 \left(\dfrac15\right)^{n-1}$

PLEASE HELP<br> A) 8<br> C) 1<br> B) 6<br> D) 7<br><br> What is the value of x?

SVEN [57.7K]

Answer: 7

Step-by-step explanation:

As tangents drawn from a common external point to a circle are congruent,

8x - 7 = 6x + 7
2x - 7 = 7 [subtract 2x from both sides]
2x = 14 [add 7 to both sides]
x = 7 [divide both sides by 2]

Help please! <br><br> Geometry R.10 Solve a right triangle

Len [333]

That is a 30 60 90 triangle
The "short" side (DE) equals the middle side (FE) times (1 / sq rt(3))
short side = 8 * sqrt(3) * (1 / sq rt(3) = 8
Hypotenuse (DF) is 2 times the short side which equals 16.
