Hello,
1) cos t* tan t=cos t* sin t/cos t =sin t (if cos t≠0)
2)cos t * cosec t =cos t /sin t =√(1-sin² t) / sin t.
let x represent the number of apples and y represent the number of oranges.
TOTAL: x + y = 112
y = 112 - x
PEELED:
3x = 4y
3x = 4(112 - x)
3x = 448 - 4x
7x = 448
x = 64
y = 112 - x
= 112 - 64
= 48
a) There are 64 apples and 48 oranges
Peeled apples: = 3(8) = 24
Unpeeled apples: 64 - 24 = 40
Unpeeled - Peeled: 40 - 24 - 16
b) there are 16 more unpeeled apples than peeled apples
Answer:
23cm
Step-by-step explanation:
to convert from millimetres to centimetres, you divide by 10.
10mm= 1cm.
so 230mm = 23cm.
Answer:
75$
Step-by-step explanation:
because 25+50=75
Answer : C
i.e. f(x) =12 when x = 9
Explanation :
Since we have given that
x=9 lies in the interval [9,13]
so f(x) will be 12 for x=9
in another interval i.e (-6,9)
x can't be 9 as it is an open interval which does not include 9 .
so we'll go for f(x)=12 when x=9.
