Answer:
1.71
Step-by-step explanation:
by using definition of cos

Answer:

Step-by-step explanation:
Slope intercept form is a way of modeling a quadratic equation, where the coefficient of the term (
) is the slope (change) of the line, and the constant is the y-intercept. In essence;(
), where (
) is the slope and (
) is the y-intercept.
The slope of the given line is (
) because, this is the rate at which the candle burns, therefore, it is the change in the line. The change is (
) because this is the rate of burning, the slope is also negative since the height is decreasing. (
) is the y-intercept because it is the starting height of the candle. One will take the time since the start of burning the candle, multiply it by the slope, and add it to the y-intercept to find the current height of the candle. Therefore, the equation is (
), where the output (
) is the current height of the candle, and the input (
) is the time at which the measruement was taken.
135 in percentage out of 100% is 1.35%
To Check This Answer
in 135(135.) move the decimal twice to the left and it becomes 1.35 you then multiply that by 100 and it will give you 135. Therefore 1.35 will become a percent which is 1.35%
The customer will pay $3.57 for the greeting card
Explanation:
The card originally costs $4 before tax and is discounted by 15%
0.15 x 4 = 0.6
4 - 0.6 = 3.4
Then the 5% sales tax is added:
0.05 x 3.4 = 0.17
3.4 + 0.17 = 3.57
