Answer:
No. There are two solutions to the point x=-2: 9 and 5.
Step-by-step explanation:
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, for the same x position, then the graph is not a function.
Answer:
4
Step-by-step explanation:
because 15 x 4 = 60
20 x 3 = 60
3.7cm on the map represents 1850km in reality
3.7cm : 1850km
1cm : 1850/3.7 km
1cm : 500km
Scale statement for map is : 1cm : 500km.
That is 1cm on map represents 500km.
1cm : 500km. Recall 1km = 1000m = 100 000cm
1cm : 500* 100000cm
1cm : 50 000 000cm
1: 50 000 000.
Scale factor is 50 000 000.
Answer:
Building a square platform for Mr. Krueger in the drama room at school:
The carpenter can use the Square Root Function to determine the side length of the square platform.
Step-by-step explanation:
The square root of the desired area of the platform, which had been provided to the carpenter will give the side length of the square platform because area of a square is equal to side length squared (L²). If the area is ascertained, to determine the length will be to get the square root of the area.
Hi there!
![\large\boxed{3\text{ } \frac{3}{4} cm^3}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B3%5Ctext%7B%20%7D%20%20%5Cfrac%7B3%7D%7B4%7D%20cm%5E3%7D)
Knowing that one cube has side-lengths of 1/2, we can calculate the dimensions for the prism:
Length: 1/2 × 5 = 2.5 cm
Height: 1/2 × 3 = 1.5 cm
Width: 1/2 × 2 = 1 cm
Use this formula to solve for the volume:
V = l × w × h
Thus:
V = 2.5 × 1.5 × 1 = 3.75 cm³
Convert to fraction:
75/100 = 3/4
Thus, the volume in mixed-numbers is 3 3/4 cm³.
