Answer: 12.0

Step-by-step explanation: We need to find the length of one of the leg piece, so this is how we will set up our equation (x is the missing side length):

1. $x^{2}$ + $5^{2}$ = $13^{2}$ (Simplify the square roots)

2. $x^{2}$ +25 = 169 (Subtract 25 from 169)

3. $x^{2}$ = 144 (Take the square root of both sides)

4. x = 12 or 12.0.

Circle O has a circumference of 367 cm.

olya-2409 [2.1K]

Answer:

none of the above

Step-by-step explanation:

The applicable relationship is ...

C = 2πr

Solving for r, we get

r = C/(2π) ≈58. (367 cm)/(2·3.14159) ≈ 58.41 cm . . . . no matching choice

When the problem does not include a correct answer choice, I usually suggest you ask your teacher to show you the working of it.

Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give

solmaris [256]

Answer:

$x=5y$

Step-by-step explanation:

We are given that

$g(x)=log_{10}(2x)$

Point(5,1)

$g(x)=\frac{ln(2x)}{log10}$

By using property

$log_x y=\frac{lny}{lnx}$

We have to find the equation of tangent line to the given graph.

Differentiate w.r.t x

$g'(x)=\frac{1}{2xlog 10}\times 2$

By using the formula

$\frac{d(lnx)}{dx}=\frac{1}{x}$

$\frac{dy}{dx}=\frac{1}{xlog 10}$

We know that Log 10=1

$m=g'(x)=\frac{1}{x}$

Substitute x=5

$m=\frac{1}{5}$

Point-slope form

$y-y_1=m(x-x_1)$

By using this formula

$y-1=\frac{1}{5}(x-5)$

$5y-5=x-5$

$x-5y=-5+5=0$

$x=5y$

Hence, the equation of tangent line to the graph

$x=5y$

Suppose that daycare costs are normally distributed with a mean equal to $10,000 a year and a standard deviation equal to $2,000

notka56 [123]

Answer:

50%, 68.26%, 95.54%

Step-by-step explanation:

Let X be the day care costs

X is N(10000, 2000)

Since normal distribution is symmetrical about the mean we get
