Answer:
a) 4
b) 3
Step-by-step explanation:
a. The total number of real and complex zeros is equal to the degree of the polynomial. That total is (1 negative real) + (3 positive real/complex) = 4 total zeros. The degree of the polynomial is 4.
The even degree is confirmed by the answer to part b, and by the end-behavior shown in the table, which has a tendency to -∞ for |x|→∞.
__
b. The intermediate value theorem tells you there will be zeros in the intervals (0, 1), (1, 2), and (2, 3) according to the values in the table. (The function changes sign in those intervals.) Thus there are 3 positive real zeros.

Stanley cannot tell anything about Descartes' rule of signs by analyzing the table of function values. To use that rule, he must have terms of the polynomial. If he has those terms, he already knows the degree of the polynomial.

hi <3
multiply the coefficient of x^2 with the last value:
2 x 3 = 6
you need to find a value that multiplies to give 6 and adds to give 5
this would be 3 and 2
now you have:
(x + 3)(x + 2)
we need to incorporate the 2 into it
you can divide the 2 by 2 so that part is fine. however, as 3 cant be divided by 2, you have to carry the 2 up as a coefficient for x
your final answer works out to be:
(2x + 3)(x + 1)
hope this helps :)

a) Find the slope of the curve y= x^3 + 3 at the point P(-2, -5)
b) Find an equation of the tangent line to the curve at P(-2, -5)
9514 1404 393
Answer:
a) 12
b) y +5 = 12(x +2)
Step-by-step explanation:
The slope of a function is its derivative.
a) The slope of y = x^3 +3 at any point is y' = 3x^2. So, at the point where x=-2, the slope of the curve is ...
m = 3(-2)^2 = 12 . . . . slope at (-2, -5)
__
b) The equation of the tangent line is most easily written using the point-slope form of the equation of a line.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y +5 = 12(x +2) . . . . line with slope 12 through point (-2, -5)

O A. The slope of the line is (Simplify your answer. Type an integer or a fraction)
O B. The slope of the line is undefined
(Answer quickly)
Answer:
Slope: - 5/4
y-intercept: - 1
Step-by-step explanation:
- 10x - 8y = 8
- 8y = 10x + 8
y = - 10x/8 -8/8
y = - 5/4x - 1

Answer:
[tex]c = 300000 {(1.05)}^{50} [/tex]
Step-by-step explanation:
The future value formula is FV=PV(1+i)^n, where the present value PV increases for each period into the future by a factor of 1 + i. value PV increases for each period into the future by a factor of 1 + i.
[tex]fv = pv {(1 + r)}^{n} [/tex]
fv = future value
pv = present value
r = annual interest rate ( decimal number)

What is mean median mode range?
Answer:
Mean- the average of data, meaning you add up all the numbers, and then divide the sum of the numbers by how many numbers there are. For example:
2, 2, 3, 4, 6, 6, 9.
7 numbers total.
2 + 2 + 3 + 4 + 6 + 6 + 9 = 32
32 ÷ 7 = 4.57
The mean would be 4.57.
Median- the middle point of the numbers. You cross off each of the numbers until you have one last number standing. If you have an even number of numbers, you find the middle of the last two numbers you crossed off. For example:
2, 2, 3, 4, 6, 6, 9
2, 3, 4, 6, 6
3, 4, 6
4
4 would be the median.
Mode- the largest number on the data.
Range- subtract the mode (largest number) from the smallest number to get range. For example:
2, 2, 3, 4, 6, 6, 9
9 - 2 = 7
7 would be the range.

Answer:
5/6 5/7 5/8 5/12? im bad at fractions sorry hope it helped tho
Step-by-step explanation:
Answer:
5/12 5/8 5/7 5/6
Step-by-step explanation:
If we divide 5 by 12 we get 0,42
If we divide 5 by 6 we get 0.83
So we know 5/12 is less than 5/6, so we just need to order the numbers in between, and as result we get:
5/12 < 5/8 < 5/7 < 5/6

harold licorice company made 6,429.4 feet of licorice in 9 days. to the nearest hundredth of a foot how many feet of licorice on average did the company make per day
Answer: 714.4
Step-by-step explanation: It says the company had made 6,429.4 feet of licorice in 9 days and you want to find the average amount made in 1 day. So what you would do is divide 6,429.4 by 9 and get 714.3777777 so on. Next its says by the nearest hundredths place meaning the 2nd placement after the dot, so what you would do is round it and you get 714.4.
