CR:RB = 2:3
CB:CB = 2:5
AQ:AB=2:5
That means we start at A and go 2/5 along the way toward B to get Q:
Answer: Q=(-2,-4)
Answer:
Step-by-step explanation:
The first part is already solved.
<u>We got the scale factor </u>
<u>Use this to find the missing side:</u>
324 pounds
24% = 
= 0.24
0.24 × 1350 = 324 pounds
He should collect 324 more pounds of waste paper
Equation of the parabola: y = ax^2 + bx + c. Find a, b, and c.
x of axis of symmetry:
x
=
−
b
2
a
=
3
-> b = -6a
Writing that the graph passing at point (1, 0) and point (4, -3):
(1) 0 = a + b + c -> c = - a - b = - a + 6a = 5a
(2) -3 = 16a + 4b + c --> -3 = 16a - 24a + 5a = -3a --> a = 1
b = -6a = -6; and c = 5a = 5
y

Check with x = 1: -> y = 1 - 6 + 5 = 0. OK
Answer:
Step-by-step explanation:
6²+8²=36+64=100=10²
so it is a right angled triangular prism.
surface area=2×(1/2 ×8×6)+(6+8+10)×7
=48+980
=1028 sq. m.
