Turning points:
All points on the function where function changes it's shape
At turning point , it will either go from increasing to decreasing or from decreasing to increasing
We can see hat
as x increase upto x=0
The value of y decreases
x-value: -6 , -4 , -2 , 0
y-value: 8 , 2, 0 , -2
But f(x) changes from -2 to -1 ..
so, it is increasing
so, function changes at x=0
that's why turning point is
(0,-2).............Answer
Answer:
2
Step-by-step explanation:
8+6+4+2+1 =21
Total 21 dots/observations
Centre at 11th dot which corresponds to 2
Answer:
∠A=65º
Step-by-step explanation:
- A angle of a line is 180º, so we can say that angle ABC=(180-6x)º
- The interior angkes of a triangle is 180º, so (x+40)º+(3x+10)º+(180-6x)º=180º
- Remove parenthesis, x+40+3x+10+180-6x=180
- Combine like terms, -2x+230=180
- Subtract 180, -2x=-50
- Divide by -2, so x=25
Now:
- ∠CAB=(25+40)º=65º
- ∠ABC=[180-6(25)]º=30º
- ∠BCA=[3(25)+10]=85º
Answer:
0.15 is the answer
Step-by-step explanation:
X(x + 2) = 120sq units
<span>Set it equal to 0 </span>
<span>x^2 + 2x - 120 = 0 </span>
<span>factor </span>
<span>(x + 12)(x - 10) </span>
<span>For the shorter side: </span>
<span>x - 10 = 0 </span>
<span>x = 10 </span>
<span>Now that you have x, solve for the longer side which we said was represented by </span>
<span>x + 2 </span>
<span>10 + 2 = 12 </span>
<span>Proof </span>
<span>A = L x W </span>
<span>120 = 10 x 12 </span>
<span>120 = 120 </span>
<span>true </span>
<span>Our length is 12 and our width is 10</span>
