Answer:
7.2 m²
Step-by-step explanation:
The area of a triangle is Bh/2
The diagram may fool you but its just 3*4.8/2 because the base is 3 and height is 4.8
so 14.4/2= 7.2 m²
Answer:
<em>Exponential growth function</em>
Step-by-step explanation:
The table below represents some function between x and y:
x - 4 - 5 - 6 - 7
y - 15 - 90 - 540 - 3240
We are required to find if it's exponential growth, decay, or neither.
An exponential function is identified because each term is calculated as the previous term multiplied by a constant factor.
The values of x grow in increments of 1 and the values of x grow by a factor of 90/15 = 6, 540/90 = 6, 3240/540 = 6
Since there is a common factor and it's greater than 1, the function is exponential growth.
Answer:
Step-by-step explanation:
The given quadratic equation is .
Comparing this equation to: , we have a=2,b=-5.
Where: and
The difference in roots is given by:
Divide both sides by -2
2.
(a) 200/4=x
(b) Yvonne is 50 because 50 times 4 is equal to 200
(c) Xavier is 43 because if you subtract 7 from 50 (which is Yvonne's age) you get 43
Well it's not really a matter of which is "best", one is right and the others are wrong :)
is an <em>irrational</em> number, meaning that it can't be expressed with a fraction between integers: in other words, there doesn't exist two integers such that
This is why option B is wrong. Also, imaginary numbers (option C) are complex numbers with no real part. Since
is not imaginary. Finally, irrational numbers are real numbers, so option D is wrong as well.
