Answer: C. 8
Step-by-step explanation:
Answer:
+1, -1, +11, -11
probably written with a +- symbol:
+-1, +-11
Maybe (silly) written like fractions:
+- 1/1, +- 11/1
Step-by-step explanation:
First list the factors of the leading coefficient. Here its 1. So we're going to use positive and negatives of the factors of 1, which is just +/- 1 . These numbers are going to go on the bottom of a fraction.
Next look for the factors of the constant, here it's 11
So that gives us
+/- 1, +/- 11 . These will go on the top of a fraction. (A fraction is a rational expression, that's why the name)
Then make all the combinations of
factors of constant
OVER
factors of leadingcoeff
So, we find
+/- 1, +/- 11
V=πr²h+(2/3)πr³
<span>πr²h+(2/3)πr³=V
</span>πr²h=V-<span>(2/3)πr³
</span>h=(V-(2/3)πr³) / (<span>πr²)
h=V/</span><span>πr² - 2/3r
Answer i: </span>h=V/<span>πr² - (2/3)r
Data:
V=245
r=7
h=(245 / 49</span>π) - (14/3)
h=(5/π) - (14/3)
h=(15-14π)/3π
h=-3.075
Answer ii: h=-3.075
Answer:
x = 0.85; y = 0.15
Step-by-step explanation:
Let the larger number = x
Let the smaller number = y
Equations
x + y = 1
x - y = 0.7
Solution
<em><u>Find x</u></em>
Add the equations together.
x + x = 1 + 0.7 Combine like terms.
2x = 1.7 Divide both sides by 2
2x/2 = 1.7/2
x = 0.85
<em><u>Find y</u></em>
x + y = 1 Substitute for x
0.85 + y = 1 Subtract 0.85 from both sides
0.85 - 0.85 + y = 1 - 0.85
y = 0.15
