ex– 1 = 9
Answer:
x = ln 10
Step-by-step explanation:
You meant e^x - 1 = 9. Let's isolate e^x, by adding 1 to both sides. We get:
e^x = 10
Now make use of the property ln a = b <=> a = e^b
Then e^x = 10 becomes
x = ln 10
Answer:sin75=√(2+√3)/2
Step-by-step explanation:
Cosx=1-2sin^2(x/2) let x=150
Cos150=1-2sin^2(150/2) cos150=-√3/2
-(√3)/2=1-2sin^2(75)
2sin^2(75)=1+(√3)/2
2sin^2(75)=(2+√3)/2
Cross multiply
2x2sin^2(75)=2+√3
4sin^2(75)=2+√3
sin^2(75)=(2+√3)/4
Take square root of both sides
sin75=√(2+√3)/√4
sin75=√(2+√3)/2
B)24
C)30
D)36
Answer:
24 years.
B is correct option.
Step-by-step explanation:
Let Sunita's current age is x and that of Mark's is y.
Hence, we have
Now, in 12 years the ratio will be 5 to 6. Thus, we have
Cross multiplying, we get
Plunging, the value of x from equation (1)
Therefore, Mark's current age is 24 years.
Mark's current age is 24
Answer:
1. 1 * =
(it will be equal to the sixth root of x cube)
2. No, the expression X
X
will be equal to
since the powers of numbers with the same base are added
3. B and D 1/ is the same as 'x'
as mentioned in the last answer, powers of numbers with same base are added. hence, option D will be which will be equal to x

Answer:
B & D
Step-by-step explanation:
Volume is calculated as:
For (a):
For (b):
For (c):
For (d):
There's no need to check for (e)
Option b and d answers the question
Using the volumeof a rectangularprismto examine the volumesof the prism,the two prisms with a volumeof 36cm³are Band D
Recall:
PrismA:
Volume = 3cm × 5cm × 4cm = 60cm³
Prism B :
Volume = 3cm × 3cm × 4cm = 36 cm³
Prism C :
Volume = 4cm × 3cm × 2cm = 24 cm³
Prism D :
Volume = 2cm × 6cm × 3cm = 36 cm³
Prism E :
Volume = 4cm × 2cm × 2cm = 16 cm³
Hence, the two rectangularprismswith a volumeof 36cm³are Band D.
