Answer:
Hi there!
As we know that the sum of all three angles of a triangle is 180°.
If ∆ABC is right angled at <u>C</u>
C = 90°
=>
=>
=>
=>
Multiplying cos both sides. We get,
=>
We know cos 90° = 0, by trigonometric ratio.
=>
So,
=>
5 gallons x gallons
------------- = ----------------
12 hours 240 hours
using cross products
5 * 240 = 12 * x
1200 = 12 x
divide each side by 12
1200/12 = 12x/12
100 =x
You will need 100 gallons
Answer:
Mia has 0.001 dollars after her donation.
Step-by-step explanation:
The maximum amount of money, Mia got from her mom is 20 dollars.
Money donated by Mia is 19.999 dollars.
So, the remaining amount of money: dollars
Hence, Mia has 0.001 dollars after her donation.
I think it’s the third one, i could be wrong
Answer:
f(x) = x +3
Step-by-step explanation:
The first differences for adjacent x-values are all 1, so this is a linear function. Because those differences are all 1, it is a linear function with a slope of 1. We observe that f(0) = 3, so that is the y-intercept.
__
The slope-intercept form of a linear function is ...
y = mx + b . . . . . where m is the slope (1) and b is the y-intercept (3).
A suitable function rule is ...
f(x) = x +3
