Answer:

D

Step-by-step explanation:

The degree of a polynomial is determined by the largest exponent of a term within the polynomial.

Given

7x³ + 4x - 5 + 8[tex]x^{5}[/tex]

The term with the largest exponent is 8[tex]x^{5}[/tex] with exponent 5

Thus the polynomial is of degree 5 → D

Answer:

y =9

Step-by-step explanation:

you know the distance is 10 and some of the x,y points. so start filling what you know into the distance formula

10= √((9-1)^2 + (y-3)^2 )

square both sides to get ride of the square root

100 = 64 + (y-3)^2

36 = (y-3)^2

6 = y-3

y = 9

double check by using 9 for Y and you'll see it works.

Answer:

The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.

Step-by-step explanation:

It's possible because they cut cakes into different number of slices.

You know that Luke, Kira and Ali each served [tex]\frac{2}{3}[/tex] of their own cake and Luke served 4 slices, Kira served 6 slices and Ali served 8 slices.

Being x the whole slices of cake, and if Luke served [tex]\frac{2}{3}[/tex] of his cake, which are 4 slices, the whole slices of cake of Luke is:

[tex]\frac{2}{3}*x=4 slices[/tex]

Solving:

x= 4 ÷[tex]\frac{2}{3}[/tex]

x= 6

Then, whole slices of Luke's cake is 6.

Performing the same approach for Kira you get:

[tex]\frac{2}{3}*x=6 slices[/tex]

x= 6 ÷[tex]\frac{2}{3}[/tex]

x= 9

Then, whole slices of Kira's cake is 9.

Finally, performing the same approach for Ali you get:

[tex]\frac{2}{3}*x=8 slices[/tex]

x= 8 ÷[tex]\frac{2}{3}[/tex]

x= 12

Then, whole slices of Ali's cake is 12.

The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.

The mathematical expression for the verbal expression is the sum of two and four and six times eight will be (2+4+6)8.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given verbal expression is the sum of two and four and six times eight will be written as:-

Add 2,4, and 6 apply parenthesis, and then multiply by 8. The expression will be:-

E = ( 2 +  4 + 6 ) 8

Therefore, the mathematical expression for the verbal expression is the sum of two and four, and six times eight will be (2+4+6)8.

Answer:

$11.76

Step-by-step explanation:

We first need to find the amount of plywood for all birdhouses.

2 3/5 * 8 = 104/5 or 20.8 or 20 4/5

Now we can solve the cost for all the birdhouses by multiplying the total amount of plywood needed by the price per square foot.

20.8 * 0.56 = $11.648 or estimated $11.65

Remember, the question might be different, so don't submit anything yet. If the people who sell the plywood only sell in integer numbers (meaning you can't buy 4/5 of a square foot of wood but can only by amounts with no fractions), then Jenna must buy 21 square feet of plywood and will have a little bit of wood left over. Now solve just like before.

21 * 0.56 = $11.76

Therefore the answer is $11.76 if she can only buy an integer amount of plywood or estimated $11.65. I think the best answer is 11.76.

Answer:

5 yr and 39 yr

Step-by-step explanation:

Let x = the age of the younger

then 7x + 4 = the age of the older

Now x + 7x + 4 = 44

8x + 4 = 44

8x = 40

x = 5

7x + 4 = 7(5) + 4 =  35 + 4 = 39

Check:  5 + 39 = 44

Answer:

a squared OR a2 OR a^2

Step-by-step explanation:

So we need to remember that numbers and exponents are different. When we divide a5 by a3, we subtract 3 from 5. That gives us 2. So the exponent is 2 and the answer is a2. I hope this helped! :)

Answer:

x = 17

Step-by-step explanation:

Assuming you require to find x

4x - 3 and 115 are same- side interior angles and supplementary, sum to 180°

4x - 3 + 115 = 180

4x + 112 = 180 ( subtract 112 from both sides )

4x = 68 ( divide both sides by 4 )

x = 17

Answer:

1 mi/hr

Step-by-step explanation:

Given that:

Speed in still water, s = 5 mi/hr

Let speed of current = x

Time = distance /speed

Upstream (subtract speed of current) = 5 - x

Upstream time = 8 / 5 - x - - - (1)

Downstream (add speed of current) = 5 + x

Downstream time = 12 / 5 + x - - - (2)

Equate (1) and (2)

8 / (5 - x) = 12/ (5 + x)

8(5 + x) = 12(5-x)

40 + 8x = 60 - 12x

40 - 60 = - 12x - 8x

-20 = - 20x

x = 1

Spwed of current = 1 mi/hr

Answer:

x = 19.06 feet

Step-by-step explanation:

Given that,

The length of a tree, h = 16 feet

It casts a shadow which forms an angle of 40° with the ground.

We need to find the length of the shadow. We can find it using trigonometry such that x be the length of the shadow. So,

[tex]\tan\theta=\dfrac{h}{x}\\\\x=\dfrac{h}{\tan\theta}\\\\x=\dfrac{16}{\tan(40)}\\\\x=19.06\ \text{feet}[/tex]

So, the length of the shadow is 19.06 feet.

Answer:

C. 1/2

Step-by-step explanation:

(-9, 6) (-3, 9)

you need to subtract the x's and y's of both coordinates.

-9 - - 3 or -9 + + 3

x = 6

then, do y.

6 - 9 = 3

y = 3

then, divide the y by the x.

3/6 = 0.5

0.5 = 1/2
