Help! What is the answer?

Answer: 22.4

Explanation:

The pieces of the chords multiply together to get the same result. This is from the intersecting chord theorem.

The first chord has pieces of 10 and x, which multiply to 10*x

This is equal to the other product found by multiplying the pieces 14 and 16 (from the other chord)

10*x = 14*16

10x = 224

x = 224/10 ... divide both sides by 10

x = 22.4

How to find the derivative of e^3㏑(x²)
vovikov84 [41]
f(x)=e^{3\ln x^2}\\\\f'(x)=e^{3\ln x^2}\cdot\dfrac{3}{x^2}\cdot2x=e^{3\ln x^2}\cdot\dfrac{6}{x}=\dfrac{6e^{3\ln x^2}}{x}\\\\\\but\ e^{3\ln x^2}=e^{\ln (x^2)^3}=e^{\ln x^6}=x^6\ where\ x\neq0\\\\therefore\ f'(x)=6x^5

denpristay [2]

Answer:

174cm^2

Step-by-step explanation:

Given data

L=9m

W=5m

H=3m

The formula for the total surface area of a cuboid is

SA=2lw+2lh+2hw

substitute

SA=2*9*5+2*9*3+2*3*5

SA= 90+54+30

SA= 174cm^2

Hence the surface area is 174cm^2
