Answer:
Yes, it is a polynomial, and the degree is 5
Step-by-step explanation:
A polynomial is a combination of terms separated using + or − signs and normally have exponents. So, this equation is a polynomial. The degree is just the highest exponential value, which is 5 because -5y is being raised to the 5th power
For the function y = (x – 4)(2x + 3)
the 2 x-intercepts are
Answer:
x=4 -3/2 =x
Step-by-step explanation:
y = (x – 4)(2x + 3)
To find the x intercepts set y=0 and solve for x
0 = (x – 4)(2x + 3)
Using the zero product property
0= x-4 0= 2x+3
x=4 -3 = 2x
x=4 -3/2 =x
Answer:
We can find the x intercepts by setting this equation equal to 0.
So we have:
0 = (x-4)(2x+3)
So we get:
x-4 = 0, x = 4
2x+3 = 0, x = -3/2
The x intercepts are 4 and -3/2

Answer:
y = 3x + 3
Step-by-step explanation:
As x increases, y increases by 3. Therefore, the slope of the function is 3.
Setting x = 0 will give an output of 3. Therefore, the y-intercept is (0, 3).
Overall, the function rule for the given data set is y = 3x + 3.

Christopher walks 5km south then walks on a bearing of 036º until he is due east of his starting point. How far is he from his starting point, to 1 decimal place?
Christopher's distance from his starting point is 3.6 km
Since Christopher initially walks South 5 km and then walks on a bearing of of 036º until he is due east of his starting point.
His distance South, his distance from his starting point and his distance from his 036º bearing, all form a right-angled triangle.
This right-angled triangle with opposite side to the angle 036º, as his distance from his starting point, x and the adjacent side to the angle 036º, as his distance 5 km south.
Since we have both the opposite and adjacent sides of a right-angled triangle,
From trigonometric ratios,
tanФ = opposite/adjacent
tanФ = x/5 km
Now Ф = 036º
So, tan36º = x/5km
x = 5 km(tan36º)
x = 5 km (0.7265)
x = 3.633 km
x ≅ 3.6 km to 1 decimal place.
So, Christopher's distance from his starting point is 3.6 km.

The sum of square root 5 and 2 square root 16 in simplest form is, √5 + 8 and it is irrational number
What is square root?In mathematics, square roots is a concept in which, if we multiply square roots of any number by itself then it will give us an original number.
if 'a' is square root of 'b' then it will represent as, a = √b.
Given that,
Two numbers
square root 5
2 square root 16
sum of square root 5 and 2 square root 16 in simplest form = ?
Sum = √5 + 2√16
= √5 + 2×4
= √5 + 8
the maximum possible simplest form is √5 + 8
As it is clear that, it is a irrational number
Because, √5 can not be written in P/Q form

Dylan is driving to a concert and needs to pay for parking. There is an automatic fee
of $5 just to enter the parking lot, and when he leaves the lot, he will have to pay an
additional s2 for every hour he had his car in the lot. How much total money would
Dylan have to pay for parking if he left his car in the lot for 6 hours? How much
would Dylan have to pay if he left his car in the lot for t hours?
Answer:
17
Step-by-step explanation:
6 x 2 = 12 so 12 + 5 = 17
Dylan would have to pay $17.
For such questions it is best to form an expression.
The parking fee has a fixed cost of $5.
It also has a cost per hour of $2.
This means that if a person spends t hours at the parking lot, they will have to pay $2 per hour for those t hours.
Expression = 2 x t = 2t
Whole expression including the fixed amount is:
5 + 2t
If Dylan parked for 6 hours therefore, he would pay:
= 5 + 2 t
= 5 + 2 x 6
= $17
Dylan would therefore have to pay $17 if he left his car for 6 hours.

2. If Bill has an apple, an orange, a pear, a grapefruit, a banana, and a kiwi at home and he wants to bring three pieces of fruit to school, how many combinations of fruit can he bring?
Answer:
6 choose 3 = 20
Step-by-step explanation:
[tex]=\frac{n!}{r!\left(n-r\right)!}[/tex]
6 choose 3 = 20
The total combinations of fruit he can bring is 20 if Bill has an apple, an orange, a pear, a grapefruit, a banana, and a kiwi at home and he wants to bring three pieces of fruit to school the answer is 20.
What are permutation and combination?A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
Bill has an apple, an orange, a pear, a grapefruit, a banana, and a kiwi at home and he wants to bring three pieces of fruit to school
Total number of fruits = 1+1+1+1+1+1
Total number of fruits = 6
n = 6
He wants to bring three pieces of fruit to school,
r = 3
Total combination:
= C(6, 3)
= 6!/(6-3)!3!
= 720/(6)(6)
= 720/36
= 20 combination
Thus, the total combinations of fruit he can bring is 20 if Bill has an apple, an orange, a pear, a grapefruit, a banana, and a kiwi at home and he wants to bring three pieces of fruit to school the answer is 20.
