Answer:

59/36π

Step-by-step explanation:

We know that an angle is measured in either degrees or radians and The arc's angle measurement, taken at the center of the circle the arc is part of, is measured in degrees (or radians)

Let's convert 90 degrees into radians

295Â° = 295 * π/180 = 59/36π

If a=4x and b=3x-3i, when find the value of the a^3b. This is simplifying imaginary number.

Nataly_w [17]

Answer:

192x^4 - 192 x^3i

Step-by-step explanation:

a^3 b

Lets find a^3

a=4x

a^3

(4x)^3

64x^3

b = 3x-3i

a^3b

(64x^3) * (3x-3i)

Distribute

64x^3*3x - 64x^3 *3i

192x^4 - 192 x^3i

The annual increase in height of cedar trees is believed to be distributed uniformly between five and ten inches. Find the proba

gayaneshka [121]

Answer: 0.6000

Step-by-step explanation:

Given : The annual increase in height of cedar trees is believed to be distributed uniformly between 5 and 10 inches.

Then the probability density function:-

$f(x)=\dfrac{1}{10-5}=\dfrac{1}{5}$

Then , the probability that a randomly selected cedar tree will grow less than 8 inches in a given year will be :-

$P(x\leq8)=\int^8_5f(x)\ dx\\\\=\int^8_5(\dfrac{1}{5})\ dx\\\\=\dfrac{1}{5}[x]^8_5\\\\=\dfrac{1}{5}\times(8-5)=\dfrac{3}{5}=0.6000$

Hence, the probability that a randomly selected cedar tree will grow less than 8 inches in a given year =0.6000
