Answer:

61

Step-by-step explanation:

Given the exponential expression, (2・3)² + 5²:

Start by multiplying 2 and 3 inside the parenthesis, before performing other mathematical operations.

(2・3)² + 5² = (6)² + 5²

Next, perform the exponential operations for (6)² and 5², then add their squared values together:

= 36 + 25  = 61

A tax preparation firm is interested in comparing the quality of work at two of its regional offices. the observed frequencies s
Veronika [31]

The sample proportion of returns with errors at the two tax offices will be 0.1389 and 0.0927 respectively.

<h3>How to calculate the sample proportion?</h3>

From the information, the the observed frequencies showing the number of sampled returns with errors and the number of sampled returns were given.

The sample proportion will be:

P1 = 35/(35 + 217)

= 35/252

= 0.1389

P2 = 28/(28 + 274)

= 28/302

= 0.0927

Mumz [18]

1 + {[(1 * 0.5) x 12] x 3}

1 + {[0.5 x 12] x 3}

1 + {6 x 3}

1 + 18

19

I'm not sure if that's a 1.000 or 1,000 so:

1,000 + {[(1,000 * .5) x 12] x 3}

1,000 + {[500 x 12] x 3}

1,000 + {6,000 x 3}

1,000 + 18,000

19,000

Use the fundamental identities and appropriate algebraic operations to simplify the following expression. (18 +tan x) (18-tan x)
andrezito [222]

Answer:

a) \left(18+\tan \left(x\right)\right)\left(18-\tan \left(x\right)\right)+\sec ^2\left(x\right)=325

b) The lowest point of y=\cos \left(x\right), 0\leq x\leq 2\pi is when x = \pi

Step-by-step explanation:

a) To simplify the expression \left(18+\tan \left(x\right)\right)\left(18-\tan \left(x\right)\right)+\sec ^2\left(x\right) you must:

Apply Difference of Two Squares Formula: \left(a+b\right)\left(a-b\right)=a^2-b^2

a=18,\:b=\tan \left(x\right)

\left(18+\tan \left(x\right)\right)\left(18-\tan \left(x\right)\right)=18^2-\tan ^2\left(x\right)=324-\tan ^2\left(x\right)

324-\tan ^2\left(x\right)+\sec ^2\left(x\right)

Apply the Pythagorean Identity 1+\tan ^2\left(x\right)=\sec ^2\left(x\right)

From the Pythagorean Identity, we know that 1=-\tan ^2\left(x\right)+\sec ^2\left(x\right)

Therefore,

324[-\tan ^2\left(x\right)+\sec ^2\left(x\right))]\\324[+1]\\325

b) According with the below graph, the lowest point of y=\cos \left(x\right), 0\leq x\leq 2\pi is when x = \pi

Armando read 20 pages of his 200-page book in 4 hours. At this rate, how long will it take him to read the entire book? (5 point
denis-greek [22]
The answer is B:40 hours. You take 200 divided by 20 to get 10 (the amount of 20 page sections he needs to read) and then multiply 10 by 4 (the speed he reads).
