Answer:
7
Step-by-step explanation:
means x*x = 49
x * x = 49
x= 7
Hope this helps :)
Have a great day!
Answer:
<em>z </em>= 9
Step-by-step explanation:
ln 63 = ln z + ln 7
We have the formula:
ln A + ln B = ln AB
So, ln 63 = ln 7<em>z</em>
7<em>z </em>= 63
Divide both sides by 7.
<em>z</em> = 9
The two integers are are mathematically given as
x=3.70
y=13.7
<h3>What is the
two integers?</h3>
Generally, the equation for the two integers is mathematically given as
x + 10 = y
1/x + 2/y = 2/3
Substitute
1/x + 2/x+10 = 2/3
Multiply by 3
3/x + 6/x + 10 = 2
Multiply by x
2 + 6x/x + 10 = 2x
Multiply by x + 3
2(x + 10) + 6x = 2x(x + 3)
2x+20+6x=2x^2+6x
-2x^2+2x+20=0
x=3.70
hence y
x + 10 = y
3.70+ 10 = y
y=13.7
In conclusion, the two integers are
x=3.70
y=13.7

Answer:
Step-by-step explanation:
I think you're asking how we use formulas to find areas and volumes.
There's no one area formula; the formula we use to calculate an area depends upon the shape.
For example, the area of a square of side length s is A = s^2.
The area of a triangle with base b and height h is (1/2)*b*h.
Similarly, the choice of formula for the purpose of calculating voume depends upon the shape of the 3-dimensional object.
For example, the volume of a cube with side length s is V = s^3.
The volume of a cylinder with radius r and height h is V = (1/3)πr^2*h.
