Answer:

10 in

Step-by-step explanation:

There are two ways to work this problem, and they give different answers. The reason for that is that the data shown in the diagram is not consistent.

Method 1

Use the area to determine the base length. The area formula is ...

A = (1/2)bh

20 in^2 = (1/2)(b)(4 in)

(20 in^2)/(2 in) = b = 10 in

The missing side dimension is 10 inches.

Method 2

Use the Pythagorean theorem to find the parts of the base, then add them up.

Left of the "?" we have ...

left^2 +4^ = 6^

left^2 = 36 -16 = 20

left = √20 = 2√5

Right of the "?" we have ...

right^2 +4^2 = 8^2

right^2 = 64 -16 = 48

right = √48 = 4√3

So, the base length is ...

base = left + right = 2√5 +4√3

base ≈ 11.400 in

The missing side dimension is 11.4 inches. (The area is 22.8 in^2.)

Ip a solid sphere with a diameter of 0.19 m is released from rest; it then rolls without slipping down a ramp, dropping through

lubasha [3.4K]

Answer: K = (1/2) mvÂ˛ + (1/2) IĎ‰Â˛, where m is the ball mass, I is the ball's moment of inertia (2/5)mrÂ˛, and Ď‰ is the angular velocity of the ball. Because the ball rolls without slipping, it is easy to see that v=Ď‰r, or r=v/Ď‰. Then, K = (1/2)mvÂ˛ + (1/2)(2/5)mrÂ˛Ď‰Â˛ = (1/2)mvÂ˛ + (1/5)mvÂ˛ = (7/10)mvÂ˛ Setting potential at the top equal to kinetic at the bottom, mgh=(7/10)mvÂ˛ v=âš{(10/7)(gh)} = [(10/7)(9.8)(0.51)]^(1/2) = 2.672m/s

Find FG FGH= 49 GH=31

Luba_88 [7]

Answer:

Step-by-step explanation:

From the given diagram;

FGH = 49

GH = 31

Using the expression to get FG;

FG + GH = FGH

FG + 31 = 49

FG = 49-31

FG = 18

Hence the measure of FG is 18

What is the first step in solving ln(x − 1) = ln6 − lnx for x?

Stels [109]

Answer:

Option C - Simplify the right side using the "difference of two logs is the log of the quotient" property.

Step-by-step explanation:

Given : Expression $\ln (x-1)=\ln 6-\ln x$

To find : What is the first step in solving the expression ?

Solution :

Expression $\ln (x-1)=\ln 6-\ln x$

Step 1 - Simplify the right side using the "difference of two logs is the log of the quotient" property.

i.e. $\ln a-\ln b=\ln(\frac{a}{b})$

Apply the first step we get,

$\ln (x-1)=\ln(\frac{6}{x})$

Therefore, Option C is correct.
