Hello! So because the value in the parenthesis is less than one, this represents exponential decay. 0.75 is 75% in decimal form. Percents are parts of 100. let's multiply that number from 100. 100 - 75 is 25. There. The rate of depreciation is 25%.
Given:
A figure of a circle. A secant and tangent of the given circle.
To find:
The correct equation.
Solution:
According the intersecting tangent secant theorem, the square of tangent is equal to the property of external segment of secant and the measure of the secant.
Using intersecting tangent secant theorem, we get
It can be written as
The required equation is .
Therefore, the correct option is B.
Answer:
9b /a^5/2
Step-by-step explanation:
9√(a^-5 b^2)
9 sqrt( a^ -5 b^2)
Rewriting sqrt as ^1/2
9 ( a^ -5 b^2)^1/2
9 ( a^ -5) ^1/2 ( b^2)^1/2
we know that an exponent to an exponent means multiply
9 a^ (-5*1/2) b^(2*1/2)
9 a^-5/2 b^1
9b a^ -5/2
We know that x^-y = 1/x^y
9b /a^5/2
Emily should expect to reach St Mark's market within 13.5 min
Step-by-step explanation:
3 mile = 5 km
1 mile = 5/3 km
Emily can cover 1 mile in 15 min
i.e, 5/3 km in 15 min
i.e, (5 X 1000)/3 meters in 15 min
i.e, 5000/3 m in 15 min
1 m she will cover in 15/(5000/3) min
=( 15 X 3 )/5000 min
so, 1500 m she will cover = (15 X 3 X 1500)/5000
= 27/2 min = 13.5 min
To change a measurement from liters to milliliters you multiply by 1000
