Answer:
shaded area = total area - the two triangles areas
total area = 5*9 = 45 cm²
first tri area = 1/2 * h *b
= 0.5 * 5 * 2 = 5 cm²
second tri area = 0.5 * 6 * 5 = 15 cm²
shaded area = 45 - 15 - 5 = 25 cm²
Answer:
no,no,yes,yes
Step-by-step explanation:
10(0)-8=-8
10(1)-8=2
10(2)-8=12
10(3)-8=22
Hello,
Let's be x and y the 2 numbers
x+y=20==>y=20-x
P(x)=x*y=x*(20-x)=20x-x²
Max(P(x))==>P'(x)=0= 20-2x==>2x=20==>x=10
A product is maximum is the 2 numbers are equals;
Numbers are 10 and 10 and product=100
Answer:
Step-by-step explanation:
a) ΔACD ~ ΔABE so the ratios of corresponding sides are the same. That is ...
CD/BE = CA/BA
CD/3.8 = 12.3/8.2
CD = 3.8×12.3/8.2 = 5.7 . . . . cm
__
b) As above, the ratios of corresponding sides are the same.
ED/AD = BC/AC
ED/9.15 = (12.3-8.2)/12.3 . . . . BC = AC - AB
ED = 9.15×4.1/12.3 = 3.05 . . . . cm
