Answer:
72mm^2 (72 mm squared)
Step-by-step explanation:
so i would work out the little triangle which is 8x6/2=<em><u>24m</u></em>m^2
then do 24x8/2 which is <u><em>96m</em></u>m^2
then take away 24 from 96 which gives the answer of <u><em>72mm^2</em></u>
Answer: other than 7
Step-by-step explanation:
Given
Equation is ![x^2+7=x^2+?](https://tex.z-dn.net/?f=x%5E2%2B7%3Dx%5E2%2B%3F)
For an equation to have no solution, the missing number can be any number other than 7
because if we put 7 then it justifies the equation i.e.
while on the other hand for a number other than 7, it does not justify the equation.
Answer:
a. The initial value is 5575
b. The decay factor is 0.35 or 35%
Step-by-step explanation:
The decay equation is given as;
y = 5575(0.65)^t
Mathematically, a decay equation can be written in the form;
A = Ir^t
where A is the amount at a time, I
is the initial value and r represents the decay rate
a. So by comparing this with what we have, we can see that the initial value is 5575
b. We want to write the decay factor
We can rewrite the equation as;
y = 5575 (1-0.35)^t
where 0.35 = 35/100 which can be said to be 35%
Your in my class and 21 a is true 21 b is false 21 c is false
