-9.5 because 1/2 simplifies to .5 and 9 is the whole number
A = 1/2bh...for h
multiply both sides by 2
2A = bh
now divide both sides by b
(2a)/b = h
Answer:
Well first you put the y-intercept on the graph. In this case it would be 15
So graph the point (0,15)
The you do the slope which is 3
so you always do rise over run for slope.
If 3 were a fraction it would be 3/1 so go up 3 points and the go right 1 point from (0,15)
hope this helps .-.
Answer:
$2315.25
Step-by-step explanation:
Given data
Principal= £2000
Time= 3 years
Rate= 5%
The compound interest expression is
A= P(1+r)^t
substitute
A= 2000(1+0.05)^3
A= 2000(1.05)^3
A= 2000*1.157625
A= 2315.25
Hence the Amount is $2315.25
Using this equation, f(3) = 23.
In order to find the value of f(3), we need to take the f(x) equation and put 3 everywhere we see x. Then we follow the order of operations to solve. So, let's start with the original.
f(x) = 2x^2 + 5sqrt(x - 2)
Now place 3 in for each x.
f(3) = 2(3)^2 + 5sqrt(3 - 2)
Now square the 3.
f(3) = 2(9) + 5 sqrt(3 - 2)
Do the subtraction inside of the parenthesis.
f(3) = 2(9) + 5sqrt(1)
Take the square root
f(3) = 2(9) + 5(1)
Multiply.
f(3) = 18 + 5
And add.
f(3) = 23
