Mathematics
1 answer:
vlabodo [156]3 years ago
7 0

Step-by-step explanation:

sin 53° = x/26

0.7986 = x/26

=> x = 26×0.7986

= 20.76

Tan 39° = 52/x

0.8098 = 52/x

=> x = 52/0.8098

= 64.21

cos x = 7/15 = 0.4667

x= arc cos 0.4667 = 62.18°

sin x = 27/46 = 0.5870

x = arc sin 0.5870 =35.94°

Tom [10]

Answer: 1,833,615

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:

A = P (1 + r) t  

Where:

p = original population

r = growing rate (decimal form)

t= years

A = population after t years

Replacing with the values given:

A = 800,000 (1+ 5/100)^17

A = 1,833,615  

Feel free to ask for more if needed or if you did not understand something.

PLZ I REALLY NEED HELP 15 POINTS
Len [333]

To find the X intercept, replace y with 0 and solve for x:

9x + 21(0) = 16

9x = 16

x = 16/9

To find the Y intercept, replace x with 0 and solve for y:

9(0) + 21y = 16

21y = 16

y = 16/21

X-intercept is 16/9

y intercept is 16/21
