False!
if you plug in x, the equation would be 512+14= 23 which is incorrect. x would have to equal 526 for this statement to be considered true.
Answer: 37
Step-by-step explanation:
if n=24
n+13 becomes 24+13
24+13 = 37
Answer:
The dimension of A is L/T^3 and the dimension of B is L/T
Step-by-step explanation:
We can write the equation but just in terms of its dimensions and work with dimension analysis to find the dimensions of the constants.
Writing the dimensions equation.
For the given equation
We can write
We can then replace the dimensions where x is a length dimension which means and t has a time dimension, , so we get
Since we are adding terms on the right side both terms must have the same dimension. That means we have
And
Finding the dimensions of A and B
We can finally solve for the dimensions of each.
For A we have
Solving for [A] will give us
Solving for [B]
Answer:
b=2.5
Step-by-step explanation:
The given line has equation:
The x-intercept is (b,0)
The y-intercept is (0,b)
The area of triangle QOP
The area of triangle QRS
The area of triangle QRS and QOP are in the ratio 9:25
We must negate the area under the x-axis.
But 0<b<4
Therefore b=2.5
VERIFY
The area of triangle QOP
The area of triangle QRS
We must take absolute value because this area is below the x-axis.
Answer:
$3787.5
Step-by-step explanation:
Given data
Cost price= $25,000
Rate of decrease= 7%
Time= 2020-2026= 26 years
Let us apply the formula
A= P(1-r)^t
substitute
A= 25000(1-0.07)^26
A=25000(0.93)^26
A= 25000*0.1515
A= $3787.5
Hence the worth will be $3787.5
