krok68 [10]

Answer:

$a = 73.84$ , $b = -23.64$ , $c = 83.97$ , $d = 21.73$

Step-by-step explanation:

1880:

The predicted value is:

$f(80) = 1.363\cdot (80) - 35.2$

$f(80) = 73.84$

The residual value is:

$\Delta f = 50.2 - 73.84$

$\Delta f = -23.64$

1920:

The predicted value is:

$f(120) = 7.8 \cdot 1.02^{120}$

$f(120) = 83.97$

The residual value is:

$\Delta f = 105.7 - 83.97$

$\Delta f = 21.73$

What is bigger, 29/40, 7/10 or 3/5

Romashka-Z-Leto [24]

Place each fraction under a common denominator. Remember, the number you multiply to the denominator must also be multiplied to the numerator

29/40 = 29/40
7/10(4/4) = 28/40
3/5(8/8) = 24/40

As seen by the fractions above, the order is 24/40, 28/40, and 29/40, <em>or</em> placed in it's original form is 3/5, 7/10, 29/40.

29/40 is the greatest, and is your answer

Please someone help me to prove this!!

shepuryov [24]

The answer : 4 sin c sin b sin a

Step by step
Formula = A+b+c = 180

B+c = 180-A

C+A= 180-B

A+B= 180-c

2 sin c • 2 cos a-b+c/ 2 cos a-b-c / 2

4 sin c cos 180-2b/2 cos a-(180-a)/ 2

4 sin c cos (90-b ) cos ( A-90)

4 sin c sin b sin A
