Step-by-step explanation:
A quadratic graph will surely help you find the solutions
X2-x-2=0
x1=2 x2= -1
Substitute each of the x value in the original equation to get the y value
(2)^2-(2)-2= 0 (2,0)
(-1)^2-(-1)-2=-2 (-1,-2)
plot the coordinates on the graph,the graph should be a curve
2.32 x 10⁵ = 232000
This can be solved by multiplying 2.32 to the product of 10 multiplied 5 times.
10⁵ = 10 * 10 * 10 * 10 *10
10⁵ = 100,000
2.32 x 100000 = 232000
The given equation is the standard form of a decimal number. It is used to write down a very large or very small number easily.
There are a lot of standard forms. Like: Standard form of an equation and Standard form of a polynomial.
Answer:
This is really easy, take away all 1s and multiplication sign.
Step-by-step explanation:
And then it means 25=25
Answer:
For right angle triangle,
we use Pythagoras theorem that is:
c = 
For question 1:
c = ?
a = 40
b = 9
putting them in formula,
c = 
c = 41
For question 2:
c = ?
a = 12
b = 13
putting them in formula,
c = 
c = approximately 17.69181
For question 3:
c = 35
a = 20
b = ?
putting them in formula,
1225 = 400 + 
= 1225 - 400
= 825
b = 5 
For question 4:
c = 37
a = 20
b = ?
putting them in formula,
1369 = 400 +
= 1369 - 400
= 969
Taking square root on both sides
b = 31.12
Hope it helps.
