What is the value of n in the diagram below?

IRINA_888 [86]

Answer:

n = 24

Step-by-step explanation:

(n + 18) and 2n are "complementary angles:" they add up to 90°.

Thus, n + 18 + 2n = 90. Combining the n terms results in 3n + 18 = 90.

Then 3n = 72. Dividing both sides by 3 results in n = 24.

n is 24, so n + 18 is 42 and 2n is 48. Note that 42 and 48 add up to 90.

Let f(x) = .............

galben [10]

Answer:

Step-by-step explanation:

g(3) = -2(3)^2 -4 = 2(9) -4 = 18-4 = 14

|f(2)| = | 2^2 -3| = | 4-3| = 1

(g(3) +2) = (14+2) = 16

4* |f(2)| = 4*1 = 4

16/4 = 4

A ski patrol unit has nine members available for duty, and two of them are to be sent to rescue an injured skier. In how many wa

alexgriva [62]

Answer:

Step-by-step explanation:

The number of two of the nine members of ski patrol unit can be chosen is equal to the combinations of 9 taken 2. This can be calculated using the formula:

$\frac{9!}{2!*(9-2)!}$

= $\frac{9!}{2!*7!}$ , where

9! =9×8×7×6×5×4×3×2×1 and

7!=7×6×5×4×3×2×1

2!=2×1 then the equation becomes:

= $\frac{9*8}{2}$ =36
