Answer:
If 5×11 = 55 and 5×9= 45, then the amount of oil would be 45 ounces.
Given a vetex (h,k) of a function parabola, the corresponding equation is:
With (h,k)=(2,5) we get the equation:
In order to find a, we use the given point (3,7) like this:
The equation is then:
Let the legs of the triangle be x and y
using Pythagorean theorem:
c²=a²+b²
the hypotenuse will be:
x²+y²=10²
x²+y²=100
x²=100-y².......i
the area of the triangle is:
A=1/2bh
A=1/2xy
⇒25=1/2xy
50=xy
x=50/y
x²=2500/y²...ii
substituting ii in i and solving for y we get:
2500/y²=100-y²
2500=100y²-y^4
this can be written as:
y^4-100y^2+2500=0
thus
y=5√2
x=50/(5√2)=5√2
thus:
Answer: (5√2,5√2)
Answer:
<h2>-a</h2>
Step-by-step explanation:
This is simply because with the illustration all numbers where the same but one is positive and the other is negative ,so when added
a + (-a) we will have the answer to be zero
