Answer:
first number is 5
second number is 7
Step-by-step explanation:
let x and y represent the first and second number
5x - 2y = 11 ........ equation 1
3x - 2y = 11.......... equation 2
so by elimination, equation 1 minus equation 2
5x - 3x - 2y - 2y = 11 - 1
2x = 10
x = 5
therefore the first number is 5
put x = 5 into equation 1
5x - 2y = 11
5(5) - 2y = 11
25 - 2y = 11
-2y = 11 - 25
-2y = - 14
y = 7
therefore the second number is 7

Answer:
The cosine of the angle is <u>positive</u>
The sine of the angle is <u>negative</u>
Step-by-step explanation:
We are given that
angle lies in fourth quadrant
and we know that
In first quadrant:
sin is positive
cos is positive
In second quadrant:
sin is positive
cos is negative
In third quadrant:
sin is negative
cos is negative
in fourth quadrant , cosine of angle is always positive
and sine of angle is always negative
so,
The cosine of the angle is <u>positive</u>
The sine of the angle is <u>negative</u>
Answer:
-1.5
Step-by-step explanation:
A power is how many times a number is multiplied by itself. So for 3, the number given, the values are as follows:
3x3=9
3x3x3=27
3x3x3x3=81
3x3x3x3x3=243
3x3x3x3x3x3=729
The next power will be greater than 1000 and therefore out of the range given.
