Answer:
19
Step-by-step explanation:
1. r(-3) is just plugging in -3 into the r(x) function where ever we see x.
1a. r(-3)=-2(-3)^2+1=-17
2. We are left with q(-17).
2a. We plug -17 into where we x in q(x).
3. q(-17)=-(-17)+2=19
Answer:
-4
Step-by-step explanation:
20 - 24 equals -4 (24 is negative because the temperature drops)
Answer:
Step-by-step explanation:
→ State the gradient formula
( y₂ - y₁ ) ÷ ( x₂ - x₁ )
→ Find x₁ , x₂ , y₁ and y₂
x₁ = 4 , x₂ = 12 , y₁ = 9 and y₂ = 20
→ Substitute in the values
→ Simplify
Option B is the correct answer
Step-by-step explanation:
When the sample space is represented in the form of tree diagram, the leaf nodes will represent the outcomes.
As there are two sides to a coin and two flips are being done,
Total outcomes will be: 2^2 = 4
We can see that option B has 4 leaf nodes and the outcomes are: {HH, HT, TH, TT}
So,
Option B is the correct answer

Step-by-step explanation:
3x^2+2xy+y2=2
6x + 2y + 2xy' + 2yy' = 0
x=1 ==> y=-1
6(1) + 2(-1) + 2(1)y' + 2(-1)y' = 0
6 - 2 + 2y' - 2y' = 0
4 = 0
