To find the x value of the vertex we do:
x =
if your quadratic function is in the form ax² + bx + c = y
x =
x =
Now we plug this x into the equation and solve for y.
y =

y =
y =

Identity
An identity is an equation that is true for all values of the variables. For example:
(x+y)^2=x^2+2xy+y^2
The above equation is true for all possible values of x and y, so it is called an identity.
Strictly speaking we should use the "three bar" sign to show it is an
identity as shown below. But it is very common to use the equal sign.
Answer:
11
Step-by-step explanation:
Plug in the variable into the equation. 7+4=11
Answer:
(a). 2.251 cm
, 2.349 cm, 2.295 cm
(b). 0.023 meters.
Step-by-step explanation:
(a). We are asked to to choose the options that shows the actual measurement of the rainfall.
Since the rounded figure is 2.3 cm, this means that either the tenths digit is 3 with hundredths digit less than 5, or tenths digit is 2 with hundredths digit greater than or equal to 5.
Let us check our given choices one by one.
Therefore, the correct choices are 2.251 cm
, 2.349 cm and 2.295 cm.
(b) We know that 1 cm equals 0.01 meters.
To convert 2.3 cm to meters, we will multiply 2.3 by 0.01.
Therefore, the rounded measurement of rain would be 0.023 meters.
Natural numbers are 1,2,3 and so on. 13th and 23rd natural numbers are 13 an 23. Half the positive difference between 13th and 23rd natural numbers = (23-13)/2 = 5.
34th even natural number = 68
When half the positive difference between 13th and 23rd natural number added to 34th even natural number, result will be = 5+68 = 73.
