Answer:
X=15ft
Step-by-step explanation:
17²-8²=225
=15
answer:
s + s + s and 3s
- this is because since there are three friends there would be THREE of whatever they buy, so those would be the answer.
All 8 markers in total will weigh 80 grams, from doing 10 times 8 markers = 80g
5x+2x+12=180
consecutive angle are supplementary
7x+12=180
7x=168
x=24
angle D=5x opposite angle are congruent
5x=120
Angle d=120
Hope it help:)
This is a differential equations problem. We are to work backwards and determine the function f(x) when given f "(x) and initial values.
<span>f ''(x) = 12x^2 + 6x − 4, when integrated with respect to x, yields:
x^3 x^2
f '(x) = 12------ + 6----- - 4x + C, or 4x^3 + 3x^2 - 4x + C, and
3 2
x^4 x^3 x^2
f(x) = 4------- + 3------- - 4------ + Cx + D, or f(x)=x^4 + x^3 - 2x^2 + Cx + D
4 3 2
Now, because f(0)=5, 5=0^4 + 0^3 -2(0)^2 + C(0) + D, so that D=5.
Determine D in the same manner: Let x=1 and find the value of C.
Then the solution, f(x), is x^4 + x^3 - 2x^2 + Cx + 5. Replace C with this value and then you'll have the desired function f(x).</span>
