−2(6x+5)=74

Simplify both sides of the equation.

−2(6x+5)=74

−2 x 6x−2 x 5=74

−12x−10=74

Add 10 to both sides.

−12x−10=74

      +10 +10

−12x=84

Divide both sides by -12.

−12x = 84

/−12   /-12

x=-7

hope it helps!

Enter the amplitude of the function f(x) . f(x)=3/4cos(3x)+4
Alisiya [41]

Answer:

The amplitude is \frac{3}{4}

Step-by-step explanation:

Let f(x) be a sinusoid function that has the following format:

f(x) = bsin(wx + s) + h

Then b is the amplitude of the function

h is the vertical displacement of the wave

s is the phase angle

\frac{2\pi}{w} is the period.

In this problem f (x) = \frac{3}{4}cos(3x) +4

Then \frac{3}{4} = b

Therefore the amplitude of the function is \frac{3}{4}

The amplitude is a measure of the vertical size of the sinx wave

How would you change 18/7 into a mix number?
RSB [31]

How many times does 18 go into 7? The answer is 2 times since 14/7 = 2 and we'll have 4 left over. We can say that 18/7 = 2 remainder 4. The remainder of 4 is placed over the denominator 7 to indicate we a fractional part.

Therefore, 18/7 = 2 & 4/7

Suppose a certain species of fawns between 1 and 5 months old have a body weight that is approximately normally distributed with
worty [1.4K]

Answer:

z

Step-by-step explanation:

Assuming this complete question:

"Suppose a certain species of fawns between 1 and 5 months old have a body weight that is approximately normally distributed with mean \mu =26 kilograms and standard deviation \sigma=4.2 kilograms. Let x be the weight of a fawn in kilograms. Convert the following z interval to a x interval.

X"

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:

X \sim N(26,4.2)  

Where \mu=26 and \sigma=4.2

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

We know that the Z scale and the normal distribution are equivalent since the Z scales is a linear transformation of the normal distribution.

We can convert the corresponding z score for x=42.6 like this:

z=\frac{42.6-26}{4.2}=3.95

So then the corresponding z scale would be:

z

Ilia_Sergeevich [38]
D is answer.
Perimeter is 2x +3x +2x + 3x = 10x where x is unknown factor of distance.
So P = 10x
Velocity is 12 km/hr = .2 km/min
P =1.6 Km = 10x
x= .16 Km 3x = .48 km, 2x=.32 km
Area = .48 X .32 Km^2
= 153600 m^2
