variety of function types can model situations in the real world. Properties or key features of functions make them more or less appropriate models, depending on the situation. You might already know about these types of functions.
Linear. These relationships have constant rates of change. The distance traveled by a car moving at a constant speed over time is linear.
Exponential. Relationships that exhibit a percent change are exponential. The growth of a financial investment collecting interest over time is exponential.
Because the prices are different, you need to use two variables, one for each price.
Let the price for the plain one be X and the price for the printed one be Y.
You would multiply the number of each shirt by the variable:
3 plain would be 3X and 2 printed would be 2Y.
You then need to add those together to get the total cost:
Total cost = 3X + 2Y
The original value of x was negative, then –x, the opposite-signed version of x, would have to be positive. For instance, if I start with x = –3, then –x = –(–3) = +3, which is positive.
Answer:
Step-by-step explanation:
Vì tam giác ABC vuông tại C nên ta áp dụng định lí pitago=> AB²=AC²+BC²=0.9²+1.5²=3.06=>AB= (3 căn bậc hai của 34)/10
sin B=AC/AB=(3 căn bậc hai của 34)/34
cos B=BC/AB
tan B= AC/BC
cot B= BC/AC
