Step-by-step explanation:

Given

p(x) = 5x² - 3x + 7 ← substitute x = 1

Without using trignometery tables find value of , cos70/sin20+cos57.cosec33 - 2cos60
Helen [10]
Here  is some thoughts on this:

cos 57  = sin (90-57) = sin 33 

so cos 57 . cosec 33 = cos 57 / sin 33 = sin 33 / sin33 = 1

2 cos 60 = 2 * 1/2  = 1

so the last 2 parts work out to 0 

now we have to find cos 70 / sin 20

sin 20 = cos 70  so this comes to 1


so finally the answer is 1

STALIN [3.7K]

Answer:

12.75

Step-by-step explanation:

12.75 rounded to the nearest tenth is 12.8, and 12.74 won't work because it will round to 12.7.

Therefore, 12.75 is the smallest possible number.

HELP ME PLEASE !!!!
lyudmila [28]

For this one, an easy way to solve it is to break it down into parts.  First lets convert 5 feet to inches.  

Multiply the number of feet by how many inches are in one foot.  

5 times 12= 60 in

Now just add the like terms

60 in + 2 in= 62 inches.

Now we see that Sarah is 62 inches tall, now we can convert to centimeters the same way.

62 times 2.54= 157.48

So that makes C your answer, Sarah is 157.48 cm tall.
