Answer:
a
Step-by-step explanation:
Given
u = (x₁, y₁, z₁ ) and v = (x₂, y₂, z₂ ) then the dot product is
u • v = (x₁ x₂ ) + (y₁ y₂ ) + (z₁ z₂ )
Then
v • w
= (5 × 9) + (- 4 × - 2) + (4 × 7)
= 45 + 8 + 28
= 81 → a
Measure of arc TS is equal to the central angle SPT. TPR is a semi circle so =180
TPR-RPS=SPT
180-110=70
Arc TS = 70 degrees
Well I don't know, and you forgot to give me any choices or suggestions.
So I'll have to calculate it. You can watch if you feel like it.
You said 5 - 4x = -3
Subtract 5 from each side: - 4x = -8
Divide each side by -4 : x = 2
Answer:
2x3+x2−x+1x
Step-by-step explanation:
Let's solve for f.
fx=2x3+x2−x+1
Step 1: Divide both sides by x.
fx=2x3+x2−x+1x
fx=2x3+x2−x1x
