1.1 × 103 - 4.9 × 102 First do 1.1 × 103
113.3 - 4.9 × 102 Then do 4.9 × 102
11.3 - 499.8 Finally do 11.3 - 499.8
-488.5 And your final answer would be negative 488.5 aka -488.5
We are given with the mathematical expression <span>sinx=cos(48) and is asked in the porblem to determine the value of variable x. In this case, we solve first cos 48 which is equal to -0.64. to determine x, we use inverse sin, that is sin-1 (-0.64) = x; x= 42 degrees. x is equal also to 90-48 according to complementary postulate.</span>
Answer:
the range of this function is [-7, 2) (Answer A)
Step-by-step explanation:
The "range" of this function is the list of all values that the function can take on according to the rule shown in the graph. The smallest such value (the smallest y-value) is -7, obtained when x = -2. The largest is just less than 2; we know this because there is an empty circle at (1, 2) instead of a shaded circle.
Thus, the range of this function is [-7, 2)
Answer:
1/4
Step-by-step explanation:
Andrew found a pan of brownies with 3/4 of the brownies left. He ate 1/3 of what was left. What portion of the whole brownies did he eat?
The size of the brownies Andre ate =
1/3 of 3/4
= 1/3 × 3/4
= 1/4
Therefore, the portion of the whole brownies that Andre ate was 1/4
