What is the approximate volume of a tree trunk is the trunk is 12 feet tall with a circumference of 4.5

Answers

Answer 1

We need to solve for the radius
circumference = radius * 2 * PI
radius = circumference / (2*PI)
radius = 4.5 / ( 6.2831853072 )
radius = 0.7161972439 feet
Formula for cylinder volume:
Volume = π • r² • height
Volume = π • ( 0.7161972439)^2 * 12
Volume = PI * 0.5129384922 * 12
Volume 19.3373255857 cubic feet

Determine the type and number of solutions of −4x^2 − 4x − 1 = 0

Help me please, I'm extremely behind in math

Answers

The question is about types and number of soultions so you must use b^2-4ac which is the experssion under the root in the quadratic formula
so
if
b^2-4ac=0 then there is one real soultion
if
b^2-4ac<0 then there are two imaginary soultions that differ in the sign between them
if
b^2-4ac>0 then there are two real soultions
so a polynomial is written in the form
ax^2+bx+c=0
so a=-4
b=-4
c=-1
so b^2-4ac=16-16=0
so one real soultion is the answer you are looking
type:real

There is an average of 3.5×10−2 kilograms of dissolved salt in each liter of seawater.

The Pacific Ocean contains approximately 6.6×1020 liters of seawater.

About how many kilograms of dissolved salt are in the Pacific Ocean?

Enter your answer, in scientific notation, in the boxes.

(blank) x 10(blank) kg

Answers

2.3x10^19 kg This is a matter of multiplication using scientific notation. First, multiply the mantissas 3.5 * 6.6 = 23.1 Then add the exponents -2 + 20 = 18 So we initially have 23.1x10^18 But 23 is too large (the number has to be greater than or equal to 1 and less than 10). So divide the 23.1 by 10 and add 1 to the exponent, getting 2.31x10^19 Then since the least accurate value we have for input has only 2 significant digits, round the result to 2 significant digits, getting 2.3x10^19 kg

What is the distance between points M and N?

___ meters.

Answers

Answer:

The distance between points M and N is 9.8m.

Step-by-step explanation:

It is given that JKL is a triangle and M and N are the mid points of the KL and JL respectively.

Now, if we join the mid points together that is MN, then we can see that the basic proportionality holds that is:

[tex]\frac{LM}{MK}=\frac{LN}{NJ}[/tex]

[tex]\frac{10.7}{10.7}=\frac{7.4}{7.4}=\frac{1}{1}[/tex] which holds.

And which also proves that MN is parallel to JK.

Now, if MN is parallel to JK, then the measure of MN will be half the measure of JK, that is:

[tex]MN=\frac{1}{2}JK[/tex]

[tex]MN=\frac{1}{2}(19.6)[/tex]

[tex]MN=9.8 m[/tex]

Thus, the measure of MN is 9.8 meters.

Find the value of x so that f || g. The diagram is not to scale.

Answers

Lines f and g are parallel with a transversal forming same side interior angles with measures 3x and 5x + 36.

Theorem: If parallel lines are cut by a transversal, then same side interior angles are supplementary.

The angles measuring 3x and 5x + 36 are supplementary, so their measures add up to 180 degrees

3x + 5x + 36 = 180

8x + 36 = 180

8x = 144

x = 18

The answer is x = 18.

Answer:

The answer is 18

How do transformations in m and b effect the graph of y=mx+b

Answers

The equation y=mx+b is called the "slope-intercept" form of the equation of a line.

It is called so because if all the solutions (x, y) of this equation are plotted, they form a line with slope m and y-intercept b.

If m is positive, the line is increasing. So if m is positive, the greater the m, the more steeper the line, in increasing direction.

If m is negative, the line is decreasing. The smaller the m, the steeper the line, in decreasing direction.

b represents the y-intercept. If b is 0, the line passes through the origin. The larger the value of b, the higher the y-intercept. The smaller the value of b, the lower the y-intercept.

A quantity x varies directly with y and inversely with z. Which expression represents the constant of variation,k?

Answers

the answer is xz/y.

Answer:

The expression represents the constant of variation k is [tex]\frac{xz}{y}[/tex].

Step-by-step explanation:

As given

A quantity x varies directly with y and inversely with z.

[tex]x \propto y[/tex]

and

[tex]x \propto \frac{1}{z}[/tex]

Than combined the above equation.

[tex]x \propto \frac{y}{z}[/tex]

[tex]x = k\frac{y}{z}[/tex]

Where k is the constant of variation.

Than

[tex]k = \frac{xz}{y}[/tex]

Therefore the expression represents the constant of variation k is [tex]\frac{xz}{y}[/tex].

if right triangle LMN, L and M are complementary angles and sin (L) is 19/20 what is cos (M)

Answers

the right answer is 19/20 which is A i hope this helps

Answer: Value of cos(M) is

[tex]\cos M=\frac{19}{20}[/tex]

Step-by-step explanation:

Since we have given that

LMN is a right angled triangle where L and M are complementary angles ,

And,

[tex]\sin L=\frac{19}{20}=\frac{Perpendicular}{Hypotenuse}[/tex]

so, we will find base now by using "Pythagorus theorem":

[tex]H^2=B^2+P^2\\\\20^2=B^2+19^2\\\\400=B^2+361\\\\400-361=B^2\\\\39=B^2\\\\\sqrt{39}=B[/tex]

As we know that side opposite to mentioned theta is considered as perpendicular as shown in the figure ,

For M as [tex]\theta[/tex]

NL will be its perpendicular and MN will be its base and to find the cos(M) we use Base and Hypotenuse.

So, now we will find cos(M) i.e.

[tex]\cos M=\frac{Base}{Hypotenuse}=\frac{19}{20}[/tex]

Hence,

[tex]\cos M=\frac{19}{20}[/tex]

The box plots show male and females grades in mathematics class: Which of the following best describes the information about the interquartile ranges?

Answers

I think the answer is "The interquartile range for females should be higher because the overall mean is higher".

Answer:

The interquartile ranges are quite close in value.

Step-by-step explanation:

We have been given two box-plots and we are asked to choose the correct statement about the interquartile ranges.

Since we know that interquartile range is difference between upper and lower quartile.

[tex]IQR=Q_3-Q_1[/tex]

Let us find IQR for the female grades in math.

We can see from box-plot representing female grades that upper quartile is about 90 and lower quartile is about 75.

[tex]\text{IQR of female grades}=90-75[/tex]

[tex]\text{IQR of female grades}=15[/tex]

Now let us find IQR for the male grades in math.

[tex]\text{IQR of male grades}=85-70[/tex]

[tex]\text{IQR of male grades}=15[/tex]

We can see IQR values for males and females are same, therefore, last statement is true.

The missing term in the factorization 18x² − 32 = 2(3x + ?)(3x − 4) is 4.

What is Factorization ?

Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form. Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.

For an integer, Factorization is decomposition of that integer in terms of smaller integers; when multiplied with each other give back that considered number. Those composing integers are called factors of that considered integers.

WE have given an expression as;

18x² − 32 = 2(3x + ?)(3x − 4)

Now we apply difference of squares;

2(9x² - 16)

2(3x + 4)(3x - 4)

2(3x-4)(3x+4)

Therefore, the missing term is 4.
