That's a scalene triangle because all the angles are different.
Step-by-step explanation:
Step one:
given data
amount deposited=$48
after the purchase of groceries
account balance= $19
cell phone bill, which= $31
Step two:
The account balance after paying for groceries will be
=19-31= $-12
she will have a deficit of $12, hence a negative account balance
<em>To start, Deena had a positive balance.
-------True</em>
<em>
</em>
<em>In this situation, 0 represents an empty bank account.
-----True</em>
<em>
</em>
<em>After paying for groceries, Deena had a negative balance.
---True</em>
<em>
</em>
<em>After paying her cell phone bill, Deena had –$12 in the account.
...True</em>
<em>
</em>
<em>The smallest balance in the account was $19.
....True</em>
The sum of 69,75,81,87,93,99 is 504.0.
The value of the Nintendo after 35 years is $2455
Since the formula f(x) = 3x² - 40x + 180 predicts the value of the Nintendo x years after 1986.
Since we require the value in 2021, x years after 1986 is 2021 - 1986 = 35 years.
Substituting x = 35 into the equation, we have
f(x) = 3x² - 40x + 180
f(x) = 3(35)² - 40(35) + 180
f(x) = 3(1225) - 40(35) + 180
f(x) = 3675 - 1400 + 180
f(x) = 2275 + 180
f(x) = 2455
So, the value of the Nintendo after 35 years is $2455
Do you think this is a realistic prediction of the value of that Nintendo?
This is not a realistic prediction for the value of the Nintendo, because, it is too high.
