Answer:
1
Step-by-step explanation:
458 = 2 × 229
885 = 5 × 177
Factors 2 and 5 are appearing only once, hence it's a multiple of 10.
Which means 1 zero at the end
Answer: 11x + 11
Step-by-step explanation:
This is two points equation. It could be done in various ways depending on the level of understanding of the topics. The formula goes thus
y - y₁ y₂ ₋ y₁ y₂ ₋ y₁
------ = ---------- or y ₋ y₁ = --------- ˣ ( x - x₁ )
x - x₁ x₂ ₋ x₁ x₂ ₋ x₁
Where x₁ = -1, x₂ = -1, y₁ = 6, y₂ = -5. Now substitute for the values in the formula above and solve.
y - 6 -5 - 6 -11 -11
------ = -------- = ---- = -----
x - (-1) -1 - (-1) -1 + 1 0
y - 6 -11
------ = -----
x + 1 0 ,
Now we cross multiply to have a linear equation
0( y - 6 ) = -11( x + 1 )
0 = -11x - 11, now multiply by -1
The equation now becomes
11x + 11
Answer:
9.8
Step-by-step explanation:
2.3 + 8 – 1/2
Rewriting the fraction as a decimal
2.3 + 8 – .5
9.8
We have this square pyramid as shown in the picture. (Actually, a cross-section is a plane. So that, it is not fully drawn in the picture. You can see only part of it). It is given that EH⊥FG and we can easily observe that the cross-section is a triangle. It is a triangle Δ EFG.
