Answer:![(-1.412,-2.124),(3.29,7.28)](https://tex.z-dn.net/?f=%28-1.412%2C-2.124%29%2C%283.29%2C7.28%29)
Step-by-step explanation:
Given
The given equation is ![2^x-2.5=2x+0.7](https://tex.z-dn.net/?f=2%5Ex-2.5%3D2x%2B0.7)
There are two functions i.e. ![y=2^x-2.5\ \text{and}\ y=2x+0.7](https://tex.z-dn.net/?f=y%3D2%5Ex-2.5%5C%20%5Ctext%7Band%7D%5C%20y%3D2x%2B0.7)
Their intersection gives the solution of the above function
From the graph, we can see that both the graph intersects at two different points i.e. at
![(-1.412,-2.124)\ \text{and}\ (3.29,7.28)](https://tex.z-dn.net/?f=%28-1.412%2C-2.124%29%5C%20%5Ctext%7Band%7D%5C%20%283.29%2C7.28%29)
Answer:
2.25
Step-by-step explanation:
substitute x = -2 into y = (2/3)^x
=> y = (2/3)^-2
=> y = 9/4 = 2.25
Answer:
Step-by-step explanation:
7.5xsin(16.7)/2.5=0.8620815595
sin-1(0.8620815595)=59.55110984
To find the unit price of each item you want to divide:
Fresh water:
$1.76 / 16 = $0.11
Spring water:
$2.40 / 20 = $0.12
So the statement that is true is B) Fresh water has a lower unit price of $0.11/ounce.
Hope this Helps!!
The partial blueprint of a house that includes 3 bedrooms is shown below. The scale is 2.75 inches : 3 feet. What is the actual length and width of Bedroom 3 in feet?
Bedroom 1 w=9.17; l= 11 in
Bedroom 2 w=7.33 in; l= 12.83
Bedroom 3 w= 11 in; l= 14.67 in
______________________________________
___________
2.75 inches : 3 or 2.75 in / 3 feet
________________
Can you see the updates?
______________
Bedroom 3 w= 11 in; l= 14.67 in
11 in * 3 feet / 2.75 in = 12 feet
14.67 in 3 feet / 2.75 in = 16 feet
_________________________
Answer
Bedroom 3 w= 12 ft ; l= 16 ft
