Answer:

1. x = 36

2. x = -2, x = 5

Step-by-step explanation:

Secant - Secant Power Theorem: 12(12 + x) = 10(18)

144 + x = 180

x = 36

Chord - Chord Power Theorem: (x - 2)(x + 7) = 4(2x - 1)

x^2 + 5x - 14 = 8x - 4

x^2 - 3x - 10 = 0

Factor:

(x + 2)(x - 5) = 0

x = -2, x = 5

-Dominant- [34]

let 'x' represent the number of all the passes for the year

350 passes = 70% of all the passes

350 passes = 70% of x

0.70x = 350

by solving we find:

x = 500 passes

If log (m + n) = log m+log n, show that m =n/n-1​
Sedbober [7]

log (m + n) = log m+ log n and proved it m =n/n-1​

Given;

If log (m + n) = log m+ log n

To show that the m =n/n-1​

Now, According to the question:

We know that,

Log (m + n) = log m + log n

Log (m + n ) = log (mn).                 [log a + log b = log ab ]

Cancelling the log on both sides.

then,

m + n = mn

=> n = mn - m

=> n = m (n - 1)

=> m = n / n - 1

Hence Proved

log (m + n) = log m+ log n and proved it m =n/n-1​

What is Logarithm?

A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2.
