Answer:
5/8
Step-by-step explanation:
Freddie swam 3/8 laps yesterday
He also swam 1/4 laps today
Therefore the total lap swam can be calculated as follows
= 3/8 + 1/4
= 5/8
Hence the total lap is 5/8
If an integer is both a square and a cube, it can be of the form:
<span>(<span>a3</span><span>)^2</span></span>
Now,
since a cube can be of the form 7k or 7k+-1(thanks to FoolForMath),
we write
<span><span>a^3</span>=7k</span>
and get the no to be
49k^2
, which is in the form of 7 times something
<span>49<span>k^2</span>=7×(7<span>k^2</span>)</span>
Now put
<span><span>a^3</span>=7k+−1</span>
Square it
and you'll get a number in the form of (7times something +1)
Answer:
×<-1
Step-by-step explanation:
if I'm not wrong you are sloving for x right?
Answer:
The possible values are a = -2.5 or a = 4.5.
Step-by-step explanation:
Composite function:
The composite function of f(x) and g(x) is given by:
In this case:
So
Value of a so that the y-intercept of the graph of the composite function (fog)(x) is (0, 25).
This means that when 
. So
Solving a quadratic equation, by Bhaskara:
The possible values are a = -2.5 or a = 4.5.
