Where is the pic so I can answer it
Suppose the length of the card board was x cm by x cm
After squares of 4cm was cut from the corner, the dimension for the box will be:
length=(x-8) cm
width=(x-8) cm
height=4 cm
thus the volume will be:
V=length*width*height
V=4×(x-8)×(x-8)=144
x²-16x+64=36
this can be simplified to form a quadratic equation given by:
x²-16x+28=0
solving the quadratic equation we get:
x=2 or x=14
Thus we conclude that the original dimensions was:
length=14 cm ; width=14 cm
Answer:
There are an infinite number of points on this graph. Two of them would be (1, 3) and (0, 0).
Step-by-step explanations:
In order to find any points on the graph, simply put the x value in to get the y value.
f(x) = 3x^4
f(x) = 3(1)^4
f(x) = 3(1)
f(x) = 3
(1, 3)
And then for the second point.
f(x) = 3x^4
f(x) = 3(0)^4
f(x) = 3(0)
f(x) = 0
(0, 0)
Answer:
1 sunflower
Step-by-step explanation:
Start at 15 then go to the left of the line graph. After count how many X there are which there is one.
The number of students which are either in algebra or physics are 23 which is the second option.
Given that:-
Total number of students = 30
Number of students both in physics and algebra = 4
Total number of students in Physics = 12
Total number of students in Algebra = 19
We have to find the number of students which are either in algebra or physics.
Number of students in physics but not in algebra = 12 - 4 = 8
Number of students in algebra but not in physics = 19 - 4 = 15
We know that:-
Number of students which are either in algebra or physics = Number of students in physics but not in algebra + Number of students in algebra but not in physics
Hence, we can write,
Number of students which are either in algebra or physics = 8 +15 = 23.
We can also do this question using Venn diagram.
