Step-by-step explanation:

follow through that diagram. l have divided it into 3 figures A, B and C

The equation of x-axis is y=0.

Draw cordidate axis and you will find that taking image of coordinate (-3, 5) along y=0 is (-3, -5)…

Only sign of y changes then it becomes (-3, -5).

Answer:

B

Step-by-step explanation:

A and B are complementary angles because their values add up to 90 degrees. <DAB is a right angle, and therefore <EAB is as well.

Answer:

266.08

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

V = pi (3)^2 (8)

V = 72 pi

V = 72(3.14)

V is approximately 266.08

OR 72pi

Answer:

x < 5

Step-by-step explanation:

the open circle above 5 means that x cannot be equal to 5

the arrow points left indicating values of x are less than 5 , then

x < 5

The required inequality for the given line is x < 5.

Inequality shows relation between two expression which are not equal to each others.

According to the given line,

The value of x is less than 5, implies that x can be 5 to -∞

Also, at x = 5, there is an open circle, implies that,

The value of x can not be equal to 5.

So the inequality can be written as,

x<5

The inequality is x<5 for the given line.

The percentage of the offspring that will have atatched earlobes as the dominant trait, is: 50%.

What is a Dominant Trait?

A dominant trait surpresses a recessive trait, and expresses itself. The allele of a dominant trait is usally denoted using capital letters.

Given the following traits:

A - attached earlobes (dominant allele)

a - unattached earlobes (recessive allele)

A cross between Aa and aa is shown in the image attached below.

The offspring having attached earlobes = 2 Aa = 50%.

Step-by-step explanation:

180-52=128

Answer:

4 terms

Degree of the 4th term = 5

Coefficient of the 2nd term = -6

Degree of the polynomial = 11

Step-by-step explanation:

Terms of polynomials:  parts of the expression that are separated by the addition or subtraction operation.

Therefore, there are 4 terms in this polynomial.

If a term of the polynomial has more than one variable, then to calculate the degree of that term, add the powers of all the variables in the term.

Therefore, the degree of the fourth term is:

[tex]-\dfrac43x^3y^2 \implies \textsf{degree}=3+2=5[/tex]

The coefficient is the constant.  Therefore, the coefficient of the second term is -6

Degree of a polynomial:  The greatest exponent of a variable in the polynomial equation.

As some of the terms in this polynomial have more than one variable, we must first calculate the degrees of the individual terms, and then select the greatest as the degree of the polynomial equation.

[tex]-2x^9 \implies \textsf{degree}=9[/tex]

[tex]-6x^2y^6 \implies \textsf{degree}=2+6=8[/tex]

[tex]9x^7y^4 \implies \textsf{degree}=7+4=11[/tex]

[tex]-\dfrac43x^3y^2 \implies \textsf{degree}=3+2=5[/tex]

Therefore, the greatest degree is 11, so this is the degree of the polynomial.

Answer:

  a) 32

  b) 2 +5n

Step-by-step explanation:

Given the stick patterns shown, with 7, 12, 17 sticks, you want to know (a) the number of sticks in pattern 6, and (b) the number of sticks in pattern n.

The numbers of sticks in the patterns shown are ...

  7, 12, 17

The differences between these numbers are ...

  12 -7 = 5

  17 -12 = 5

That is, the first pattern has 7 and the common difference between patterns is 5. This indicates the sequence is arithmetic.

The general term of an arithmetic sequence with first term a1 and common difference d is ...

  an = a1 +d(n -1)

  an = 7 +5(n -1) = 7 +5n -5

  an = 5n +2 . . . . . . sticks in pattern n

The term when n=6 is ...

  a6 = 5·6 +2 = 32 . . . . . . sticks in pattern 6

__

Additional comment

We find it easier to determine sticks in pattern 6 by first determining the formula for pattern n.

The average thickness of a chicken eggshell being 0.000356 m is written as a single digit times an integer power of 10 as: 4 × 10^{-4} (approx)

The number is written in the form  [tex]a \times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]

The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).

Scientific notations have some of the profits as:

Better readability due to compact representation

Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.

We're given that:

Average thickness of a chicken eggshell = 0.000356 m

We can rewrite it as:

[tex]0.000356 = \dfrac{356}{1000000} = \dfrac{3.56}{10000}= \dfrac{3.56}{10^4} = 3.56 \times 10^{-4}[/tex]

Since we need to write it as a single digit times an integer power of 10, therefore, we get:
[tex]3.56 \times 10^{-4} \approx 4 \times 10^{-4}[/tex]

Thus, the average thickness of a chicken eggshell being 0.000356 m is written as a single digit times an integer power of 10 as: 4 × 10^{-4} (approx)

The value of x which will make the provided triangles similar by the sss similarity theorem is 77.

The SSS similarity theorem is the theorem which is used to check the two triangle are similar or not.

SSS means the side-side-side. This theorem states that if all the three sides of a triangle are proportional to the three corresponding sides of the another triangle, then the triangles are similar.

In the given image, the sides of the first triangle are 35,20 and 20. The sides of the second triangle are x, 44,44.

Thus, by the SSS similarity theorem,

[tex]\dfrac{x}{35}=\dfrac{44}{20}\\x=\dfrac{44\times35}{20}\\x=77[/tex]

The value of x which will make the provided triangles similar by the sss similarity theorem is 77.

Remark

There are two ways of calculating % error. Chemistry uses one way. Most others use the second method. I have used the second method.

Measurements

L = 10 in

w = 9 in

h = 4.5 in

Estimated result

350 cubic cm

Solution

Find the volume from the measurements of the Prism

V = L * w * h

V = 10 * 9 * 4.5

V = 405 in^3

Percent Error

% error = 100 * (Calculated Value - Estimated value)/(Estimated Value)

% error = 100 * (405 - 350)/350

% error = 100 * ( 55) / 350

% error = 15.71      

% error = 15.7      (rounded)
