Which is true about the degree of the sum and difference of the polynomials 3x5y – 2x3y4 – 7xy3 and –8x5y + 2x3y4 + xy3?

Answers

Answer 1

Answer: For polynomials having to or more variables, degree can be of a term or of the polynomial. The degree of a term is the sum of the exponents in a specific term while the degree of a polynomial is the highest value of all the degree of a term in the given polynomial. For the polynomial given, the degree of the polynomial is 7.

Answer 2

Answer:

Answer:

The sum has a degree of 6, but the difference has a degree of 7

Which logarithm is equivalent to log3^10 – log3^2?

Answers

$log_(3)(10) - log _(3) (2)$

Apply log rule:

$log _(c)(a)-log _(c) (b) = log _(c) ( (a)/(b) )$

$log _(3) (10)-log _(3) (2) = log _(3) ( (10)/(2) )$

$log _(3) ( (10)/(2) )$

Divide 10 by 2 :

$log _(3) (5)$

There are 200 students in the 7th grade class at Manchester Middle School. Of these students, 22% play football and 12% play baseball. Eight students play on both teams. What is the probability that a student plays either football or baseball?

Answers

Answer: There is 30% student plays either football or baseball.

Step-by-step explanation:

Since we have given that

Total number of students = 200

Percentage of students who play football = 22%

Number of students who play football n(F) is given by

$0.22* 200\n\n=44$

Percentage of students who play baseball = 12%

Number of students who play baseball n(B) is given by

$0.12* 200\n\n=24$

Number of students who play on both teams n(F∩B) = 8

According to rules, it becomes,

$n(F\cap B)=n(F)+n(B)-n(F\cap B)\n\nn(F\cap B)=44+24-8=60$

Probability that a student plays either football or baseball is given by

$(60)/(200)\n\n=0.3\n\n=30\%$

Hence, there is 30% student plays either football or baseball.

. If B is a complement of A, and C is a supplement of B, find these measures. A
equals 40

Answers

complementary angles add up to 90
so if A and B are complementary....and A = 40, then B = 90 - 40 = 50.

supplementary angles add up to 180
so if B and C are supplementary, and B = 50, then C = 180 - 50 = 130

What units could you use to measure the height of a hexagonal prism?cm
cm 2
cm 3
cm 4

Answers

Answer: A. cm

Step-by-step explanation: The formula for the volume of a hexagonal prism is, volume = [(3√3)/2]a2h cubic units where a is the base length and h is the height of the prism. We can also use the other formula V = 3abh, where a = apothem length, b = length of a side of the base, and h = height of the prism.

A certain species of tree grows an average of 3.8 cm per week. Write an equation for the sequence that represents the weekly height of this tree in centimeters if the measurements begin when the tree is 5 meters tall.

Answers

The answer is f(x) = 500 + 3.8x

The number of weeks is x. So, weekly, the tree grows 3.8x.
If the measurements of the growth begin when the tree started to grow, the equation would be: f(x) = 3.8x.
But, the measurements begin when the tree is 5 m tall. Since 1 m is 100 cm, this means that 5 m is 500 cm. Thus, the equation for the sequence that represents the weekly height of this tree in centimeters if the measurements begin when the tree is 5 meters tall is:
f(x) = 500 + 3.8x

Answer:

$n=500+8(n-1)$

DO NOT FORGET that the tree is already 5 meters tall on the FIRST WEEK, not the 0th week. So, f(x)=500+3.8x is incorrect.

(For example, on the second week the tree should be 503.8 meters tall. But if you plug 2 in f(x)=500+3.8x, you would get 507.6, which is the height of the tree on the third week.)
