17) 3*5 + 4 = 19
18) 2 * 3 = 6
19) 3 * 36 + 2 * 6 + 1 = 121
20) 5 * 49 + 6 * 7 = 287
21) 6 * 64 + 6 * 8 + 6 = 438
22) 1 * 81 = 81
23) 1 * 8 + 1 * 4 = 12
24) 7 * 729 + 5 = 5108
25) 1 * 1296 + 5 * 216 + 2 * 36 = 2448
26) 1 * 16 + 1 * 2 = 18
27) 4 * 3125 + 1 * 25 + 2 * 5 + 3 = 12538
This kind of exercise can be real drudgery. But it's almost all simple arithmetic, so better you than me. I'll do one of these for you, which will show you how to do the other one.
a). sin · cot / sec
You're supposed to know that [ cotangent = cosine/sine ]
and [ secant = 1/cosine ].
Then the problem becomes
sin · (cos/sin) / (1/cos) = cos²
Aw shucks, I might as well also set up 'b)' for you:
b). cos · csc / tan
You're supposed to know that [ cosecant = 1/sine ]
and [ tangent = sine/cosine ].
Then the problem becomes
cos · (1/sin) / (sin/cos) = (cos/sin)²
Now simply plug in the given values of cos A and sin A .
And may I compliment you on your nail care !
Answer:
I think it's B
Step-by-step explanation: I hope that helps
Answer:
Step-by-step explanation:
The "hot hand" is the notion where people believe that after a string of successes, an individual or entity is more likely to have continued success. Psychologists believe that the hot hand is a fallacy that stems from the representative heuristic, as identified by behavioral economics.
Answer:
B. Function 2
Step-by-step explanation:
Line P gradient is
Gradient = rise/run
= 1/4
Negative slope so gradient is - 1/4
Out of all the gradient, the lowest value has to be function 2 or line p & not 1/4r-5 because when r is 1 we get a gradient of 1.
-1/4xr - 5
-1/4x1 - 5
-1/4-5
-1/-1 = 1
Plus, 1 is greater than - 1/4 or - 0.25.
