Answer:
WHR
Step-by-step explanation:
BECAUSE LAST LETTER IS WHR
: Let y = f(x) = x^1/3
Then dy = 1/3*x^(−2/3) dx
Since f(64) = 4.
We take x = 64 and dx = ∆x = 1
This gives dy = 1/3*(64)^(−2/3)* (1) = 1/48
∴65^(1/3) = f(64 + 1) ≈ f(64) + dy = 4 + 1/48 ≈ 4.021 <span>

Answer:
y=3x
Step-by-step explanation:
The equation of a line can be written as 'y=mx+b', where 'm' is the slope, 'b' is a number, and 'x' and 'y' represent the 'x' and 'y' co-ordinates of any point on the line.
To find the slope m, take two points (x₁,y₁) and (x₂,y₂) and use the formula
m= (y₂-y₁)/(x₂-x₁)
Our points are (1,3) and (2,6):
(6-3)/(2-1)=3/1=3
Now that we have found the slope, we can write the equation as
y=3x+b
To find b, sub in a point:
9=3(3)+b
9=9+b
b=0
So our equation is y=3x
Answer:
D. Step 1 only.
Step-by-step explanation:
Here, Josie didn't use the distributive property correctly. The other two steps are still right, so D is correct.
How it should have been done:
x + 3 + 7x(x - 5)
<em>Use the distributive property to multiply 7x by x - 5.</em>
x + 3 + 7x² - 35x (The boldened part is what should have happened for Step 1)
<em>Combine x and -35x to get -34x.</em>
7x² - 34x - 3 is what the earlier equation should be simplified to.
