Answer:
b.
Step-by-step explanation:
Stem is the first digit and the leaf is the last digit.
Below the table is explained that 1 l 7 is 1.7 because it also could mean 17. So with that clear the terms from the Stem l Leaf are as follow:
1 combined with 3, 7 and 7:
1.3, 1.7 and 1.7
2 combined with 6, 8 and 8:
2.6, 2.8, 2.8
3 combined with 5 and 7:
3.5 and 3.7
All the terms:
1.3, 1.7, 1.7, 2.6, 2.8, 2.8, 3.5, 3.7
Answer:
4
Step-by-step explanation:
Answer:
length = x + 5
Step-by-step explanation:
Given
area = x² + 8x + 15 and area = length × width
We require to factorise x² + 8x + 15
Consider the factors of the constant term (+ 15) which sum to give the coefficient of the x- term (+ 8)
The factors are + 5 and + 3, since
5 × 3 = 15 and 5 + 3 = 8, thus
x² + 8x + 15 = (x + 5)(x + 3)
x + 3 is the width, thus x + 5 is the length
152.6315 is because If you dived 870 by 5.7 it will be that.
Answer:
a. 360.323 m
b. 
Step-by-step explanation:
Distance covered from A to B = speed x time
= 110 x 2.8
= 308 m
Distance covered from B to C = speed x time
= 110 x 1.7
= 187 m
The sum of angles at B =
+ 
= 
a. The distance of the plane from it starting point to C can be determined by applying the cosine rule.
=
+
- 2ac Cos B
Sot hat;
=
+
- 2(187 x 308) Cos 
But, Cos
= 0
So that,
=
+ 
= 34969 + 94864
= 129833
b = 
= 360.323
The distance from A to C is 360.323 m.
b. Applying the sine rule;
=
=
=
Sin A = 
= 0.5190
⇒ A =
0.5190
= 
The bearing of the plane from its original location =
