Mathematics
1 answer:
Verizon [17]3 years ago
7 0

Answer:

8) Number of terms : Monomial

Degree : Constant polynomial

9) Not a polynomial

Step-by-step explanation:

8) Recall that a polynomial with one term is a monomial

A polynomial with a degree of zero is a constant polynomial

Therefore 1 is a monomial, when we classify by number of terms and it is a constant polynomial when we classify by degree since the degree is zero.

9) Note that a polynomial has positive integral indices, therefore  \sqrt{x} +5 is not a polynomial.

The reason is that, \sqrt{x} +5=x^{\frac{1}{2} }+5 but \frac{1}{2} is not an integer.

The sum of two complimentary angles is 90. . For one pair of complimentary angles, the measure of the first angle is 15 less tha
soldi70 [24.7K]

Answer:

x=55 \textdegree

y=35 \textdegree

Step-by-step explanation:

From the question we are told that

Sum of two angle =90

First angle is 15 less than twice the measure of the second angle.

Generally interpreting mathematically we have

Let x be the first angle and second angle y

x=2y-15

Therefore

2y-15 +y=90

3y=105

y=\frac{105}{3}

y=35 \textdegree

Therefore

x+35=90

x=90-35

x=55\textdegree

Yemi is 5 years older than kunle.The product of their ages is 750. How old is kunle.​
Alex

Answer:

Kunie is 25

Step-by-step explanation:

Let's make Yemi's age y, and Kunie's age k.

Because Yemi is 5 years older that Kunie, k + 5 = y.

Because the product of their ages is 750, k * y = 750.

With substitution, we can determine that k * (k + 5) = 750.

Then with distributive property we can simplify the equation to get k^2 + 5k = 750.

Then we bring all the terms to one side of the equation to get k^2 + 5k - 750 = 0.

Then with quadratics, we can factor the equation to get (k + 30)(k - 25)=0.

Thus, either k + 30 must equal 0, or k - 25 must equal 0.  Thus, k must equal 25 or -30, and because someone cannot be -30 years old, k = 25.

Then, because Yemi is 5 years older than Kunie, y = 30.

Hope it helps <3

A cylinder of metal with a mass of 23.6546 g is submerged in a graduated cylinder containing 25.20 mL of water. The water level
PSYCHO15rus [73]

Answer:

e. 5.0329 g/mL

Step-by-step explanation:

Density is defined as mass divided by volume of an object. The volume displaced is:

v=29.90mL-25.20mL\\=4.7mL

#Density is then calculated as:

d=\frac{23.6546g}{4.7mL}\\\\=5.0329g/mL

#Correct significant figures should correspond to the highest given in the question.

Hence the density of the metal is 5.0329g/mL

Travka [436]

Answer:

36 ounces

Step-by-step explanation:

If 1 cup equals 8 ounces, you would multiply 4 1/2 by 8. 8 x 4 is 32 (ounces), and half of 8 is 4, so 4 ounces. You would then add 32 and 4 together to get your answer. Hope this helps!!
