Answer:
The absolute maximum is 4, and the absolute minimum is 2.
Step-by-step explanation:
We are given the function:
[tex]f(x)=x^4-3x^2+4[/tex]
And we want to find the absolute extrema of the function on the interval [-1, 1].
So, we will find the smallest and largest y-value within the interval. First, we can evaluate the function at its endpoints. So:
[tex]f(-1)=(-1)^4-3(-1)^2+4=2[/tex]
And:
[tex]f(1)=(1)^4-3(1)^2+4=2[/tex]
Our endpoints are (-1, 2) and (1, 2).
Recall that extrema only occurs at critical points. Critical points are where the derivative of the function equals 0. So, we can find the derivative of the function:
[tex]\displaystyle f'(x)=\frac{d}{dx}\left[x^4-3x^2+4\right][/tex]
Differentiate:
[tex]f'(x)=4x^3-6x[/tex]
Set the function equal to 0:
[tex]0=4x^3-6x[/tex]
Solve for x. Factor:
[tex]2x(2x^2-3)=0[/tex]
Zero Product Property:
[tex]2x=0\text{ or } 2x^2-3=0[/tex]
Solve for each case. Therefore:
[tex]\displaystyle x=0\text{ or } x=\pm\frac{\sqrt6}{2}[/tex]
The second case is outside of our interval. So we can ignore it.
Evaluate the function at x = 0:
[tex]f(0)=(0)^4-3(0)^2+4=4[/tex]
Therefore, for our function on the interval [-1, 1], the absolute maximum is 4, and the absolute minimum is 2.

APR of 0.995%. How much money would a $1000 investment be worth at the end of 5 years
Answer:
The amount in 5 years will be $1,050.75
Step-by-step explanation:
Here, we want to calculate the worth of the given amount of money in the next 5 years
We use the compound interest formula here;
A = P(1 + r/n)^nt
A is the amount after the given number of years
P is the amount invested which is $1,000
r is the rate which is 0.995% which is 0.995/100 = 0.00995
n is the number of times per year interest is compounded and that is 1
t is the number of years which is 5
substituting these values, we have
A = 1000( 1 + 0.00995/1)^5
A = 1000(1.00995)^5
A = $1,050.75
Clayton is plowing a wheat field. There are a total of 240 acres to be plowed. If he can plow 5 acres per hour, which equation would
represent A the number of acres left to plow, after Clayton has plowed for h hours?
CA A=5-240h
B. A = 240 + 5h
CA=5+240h
OD. A = 240 - 5h
Answer:
A = 240 - 5h

A movie theater sells morning tickets (m) for $4 and regular tickets (e) for $6. During one week, the theater earned $6000. The theater sold 890 more regular tickets than morning tickets.
Write a system of liner equation to represent this situation. (Solve by using Systems by Substitution)
Answer:
Step-by-step explanation:
Answer:
m = 66 & e = 956
Step-by-step explanation:
Create your equations:
$4m + $6e = $6000
m + 890 = e
Substitute/solve for morning tickets:
$4m + $6e = $6000 <-- m + 890 = e
$4m + $6(m + 890) = $6000
$4m + $6m + $5340 = $6000
$10m = $6000 - $5340
m = $660/$10
m = 66 morning tickets
Solve for Regular tickets:
m + 890 = e <--- m = 66
66 + 890 = 956
e = 956 regular tickets
Double check work:
$4m + $6e = $6000
$4(66) + $6(956) = $6000

How do I find the measurement of Angle x?
Answer:
26°
Step-by-step explanation:
The angle 123° is on a straight line. All angles on a straight line add up to 180°, so the first thing you should do is subtract 123 from 180.
(180-123)
Now, your answer should be 57°, and that is equal to angle W.
You now know two angles. Angles in a triangle add up to 180°, too, so all you do now is the following:
97 + 57 = 154
180- 154 + 26
And there's your answer!

In Juan's coin bank there are nickels (n),
dimes (d), and quarters (q). The number of
quarters is one-quarter the number of dimes, and
the number of nickels is twice the number of
quarters. The total value of the coins is $6.00.
Find the number of each type of coin. [Show all
work.]
Answer:
The answer is 8 quarters, 16 nickles, and 32 dimes
Step-by-step explanation:
First, the equation would be (2/4d) x 5 +d x 10 +1/4d x 25= 600 (Don't put 6.00, that's dollars. We put 6 dollars into cents to make it easier.) Then we slowly start to solve: 10/4d + 10d + 25/4d = 600 10d+40d+25d/4 = 600 (Put all of that over 4, not first 25d) 75d= 600 x 4 d=600 x 4/75 (same here put everything over 75) d=32 So then n= 2 x 32/4 = 16 Then n would be equal to : 1/4d= 1/4 x 32 = 8 So your answer would be 8 quarters, 16 nickles, and 32 dimes.Hope this helped :)

What is the probability of rolling a 1 ora 4 on a number cube labeled 1 through 6?
Answer:
For each number, there is a 1/6 probability of rolling it (so 1/6 for the 1 and also 1/6 for the 4).
This means that the probability of rolling either a 1 or a 4 on a given roll is
1 /6 + 1 /6 = 2/6 = 1/3
hope this answer helps you.....

Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form?
y = 2 (x + seven-halves) squared minus one-fourth
y = 2 (x + seven-halves) squared minus one-half
y = 2(x + 7)2 – 73
y = (x + 7)2 – 24
Answer:
y = 2 (x + seven-halves) squared minus one-fourth [y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex] ]
Step-by-step explanation:
We know that,
vertex form is y = a(x-h)² + k
vertex is (h, k)
Now,
Given that the equation is -
y = (x+3)² + (x+4)²
= x² + 3² + 2×3×x + x² + 4² + 2×4×x
= x² + 9 + 6x + x² + 16 + 8x
= 2x² + 14x + 25
= [tex]x^{2} + 7x + \frac{25}{2}[/tex]
= [tex]x^{2} + 7x + \frac{25}{2} + \frac{49}{4} - \frac{49}{4}[/tex]
= [tex](x + \frac{7}{2} )^{2} + \frac{25}{2} - \frac{49}{4}[/tex]
= [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex]
∴ we get
The vertex form is -
y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex]
So,
The correct option is - y = 2 (x + seven-halves) squared minus one-fourth (y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex] )
