Answer:
A
Step-by-step explanation:
First, you take base*base*height. Therefore;
A= a+b/2h
= 1.9+3.7/2 * 0.9 = 2.52
Hope this helped!
Answer:
Both amplitude and coefficient are equal.
Step-by-step explanation:
Given the equation y = 50 sinx. we have to find the relationship between the amplitude of y = 50 sinx and the coefficient 50.
For the curve y = a sin x, the variable 'a' represents the amplitude of graph i.e
Amplitude=|a|
Hence, for the curve y = 50 sinx
Amplitude=|a|=|50|=50
which is equal to the coefficient 50.
Hence, both amplitude and coefficient are equal.
So to find x, you have to add both A and B which is 38. Since AuB (excluding the overlap) is 29, subtract 38 from 29 and you get 9 for x.
Answer : She will hike about 18 kilometers in 6 hours .
Explanation :
Since we have given that
on every 4 hours , she hikes about 12 kilometers
![\text{on every 1 hour, she hikes about }\frac{12}{4}\text{ kilometers}](https://tex.z-dn.net/?f=%5Ctext%7Bon%20every%201%20hour%2C%20she%20hikes%20about%20%7D%5Cfrac%7B12%7D%7B4%7D%5Ctext%7B%20kilometers%7D)
![i.e. 3\text{ kilometers}](https://tex.z-dn.net/?f=i.e.%203%5Ctext%7B%20kilometers%7D)
![\text{So , every 6 hours, she hikes about =}6\times 3\text{kilometers}=18\texr{ kilometers](https://tex.z-dn.net/?f=%5Ctext%7BSo%20%2C%20every%206%20hours%2C%20she%20hikes%20about%20%3D%7D6%5Ctimes%203%5Ctext%7Bkilometers%7D%3D18%5Ctexr%7B%20kilometers)
Hence, she will hike about 18 kilometers in 6 hours .
