Side length = 5 in
<u>Step 2: Solve for </u><em><u>A</u></em>
- Substitute: A = (5 in)²
- Evaluate: A = 25 in²
And we have our final answer!
Step-by-step explanation:
11)
d=√[(-2-(-3))^2+(3-10)^2]=√(-2+3)^2+(-7)^2
=√1+49=√50=7.07 approximately
12)
M (((-1)+(-7))/2 , (2+(-4))/2)=(-8/2 , -2/2)=(-4 ,-1)
Answer:
no
Step-by-step explanation:
6^2+7^2=9^2
36+49=81
no its not a right triangle
Use the remainder theorem: it says that if <em>x</em> - <em>c</em> is a linear factor of a polynomial <em>f(x)</em>, then the remainder upon dividing <em>f(x)</em> by <em>x</em> - <em>c</em> is equal to <em>f(c)</em>.
In this case,
<em>f(p)</em> = <em>p</em>⁴ - <em>p</em>² - <em>p</em> - <em>k</em>
and <em>p</em> - 1 is a factor of <em>f(p)</em>. We have
<em>f </em>(1) = 1⁴ - 1² - 1 - <em>k</em> = -(<em>k</em> + 1)
Because <em>p</em> - 1 divides <em>f(p)</em>, the remainder is 0, which means
-(<em>k</em> + 1) = 0
<em>k</em> + 1 = 0
<em>k</em> = -1
Answer:
9 times 800/9 equals 800. (Answer is 800/9)
Step-by-step explanation:
<u>Key skills needed: Equation, Division, Fractions</u>
1) Let's say the number is the variable "x".
2) So this means 9 times x = 800
9x = 800
3) Divide both sides by 9 and you will get x equal to 800/9. If you want this in mixed number form, it is --> 88 8/9
