Find the maximum(s), minimum(s), interval(s) of increasing, interval(s) of decreasing, end behavior and symmetry for the function f(x)=x^4-8x^2+16.SOMEONE HELP ME
Answer:
Step-by-step explanation:
f(x) = x⁴ - 8x² + 16
f'(x) = 4x³ - 16x = 4(x³ - 4x) = 4x(x² - 4) = 4x(x - 2)(x + 2)
f'(x) = 0, x = 2, -2
f"(x) = 4(3x² - 4)
f''(0) = -16 < 0, f""(2) = f''(-2) 3(12 - 4) > 0
so f(2) and f(-2) are minimum values
f(0) is maximum value.
f(0) = 16, f(2) = f(-2) = 2⁴ - 8*2² + 16 = 0
Maximum = 16, minimum value = 0
-∞ < x < -2, f'(x) < 0
-2 < x < 0, f'(x) > 0
0 < x < 2, f'(x) < 0
2 < x < ∞, f(x) > 0
increase: (-2, 0) and (2, ∞)
decrease: (-∞, -2) and (0, 2)

Answer:
[tex]\csc(\theta)[/tex]
Step-by-step explanation:
[tex]\cot(\theta)=\dfrac{1}{\tan(\theta)}=\dfrac{\cos(\theta)}{\sin(\theta)}[/tex]
[tex]\sin^2(\theta)+\cos^2(\theta)=1[/tex]
[tex]\implies \sin(\theta)+\cos(\theta)\times\cot(\theta)=\sin(\theta)+\cos(\theta)\times\dfrac{\cos(\theta)}{\sin(\theta)}[/tex]
[tex]=\sin(\theta)+\dfrac{\cos^2(\theta)}{\sin(\theta)}[/tex]
[tex]=\dfrac{\sin^2(\theta)}{\sin(\theta)}+\dfrac{\cos^2(\theta)}{\sin(\theta)}[/tex]
[tex]=\dfrac{\sin^2(\theta)+\cos^2(\theta)}{\sin(\theta)}[/tex]

The upper-left coordinates on a rectangle are (-1,4), and the upper-right coordinates are (3,4). The rectangle has a perimeter of 24 units.
Answer:
The area would be 32
Step-by-step explanation:
Let's call the side lengths a and b, so then therefore a + b = 12
after this, we know that the length of a is 4, from the distance formula, and so the length of b is 8, so the area is 4*8 which is 32

Johanna budgets $1,471 each month for fixed expenses. What percent of her net monthly income is that if she nets $2,611 semimonthly? Make answer a percent then round to a whole percentage. Do not put the % sign in blank as it already knows it is in percentage form.
28%
Step-by-step explanation:
How to calculate the percentage
From the information given, Johanna budgets $1,471 each month for fixed expenses his net 2,611 semi monthly.
The percentage will be;
= 1,471/(2,611 × 2) × 100
= 1,471/5222 × 100
= 28.1692837993
= 28%

Eve plays basketball. She makes 5 free throws for every 3 free throws that she misses. If she missed 36 free throws at her last practice, how many free throws did she make?
Answer:
60
Step-by-step explanation:
We can write a proportion to solve
5 made x made
------------ = -----------
3 missed 36 missed
Using cross products
5 * 36 = 3x
Divide each side by 3
5 * 36/3 = 3x/3
50 = x
She made 60

Which ordered pair represents the reflection of the point (-4, 6) across both axes? O (4,6) O (4, -6) 0 (-4,6) O (-4,-6)
Reflecting across the Y axis, the y value stays the same and the X value become opposite:
(-4,6) would become (4,6)
Now reflecting across the X axis the x value remains the same and the Y value becomes the opposite:
(4.6) would become (4,-6)
Answer: (4,-6)
50PTS Chef Alfredo has noticed some changes in his business. He usually sells 45 pizzas on
Sunday afternoons. During football season, he has big television screens televising NFL
games and he sells 72 pizzas. What is the percent change and is it an increase or

How do I solve this step by step?
Answer:
larger #=32
smaller #= 26
Step-by-step explanation:
We can solve this by using x for the larger number.
larger #= x
smaller #= x-6
x+x-6=58
2x-6=58
2x=64
x=32
The larger number is 32. To find the smaller # you simply substitute the variable x-6 which is now 32-6 which is 26.
Hope this helps!
Answer:
smaller number = 26
larger number = 32
Step-by-step explanation:
x = smaller number
y= larger number =x+6
so
x+y=58
x+6+x= 2x+6=x58
2x=58-6=52
x=522= 26
y=x+6=26+6 = 32
checking
x+y=58
26+32= 58
