Answer: -2x^6+x^5-x^3-2+2x^2 Hope that helps!
Step-by-step explanation:
1. Remove Parentheses x^6-2x^5-x^3-7-3x^6+3x^5+2x^2+5
2. Collect like terms (x^6-3x^6)+(-2x^5+3x^5)-x^3+(-7+5)+2x^2
3. Simplify and your answer would be -2x^6+x^5-x^3-2+2x^2
The circumference of the ellipse approximate. Which equation is the result of solving the formula of the circumference for b?
c=2\pi \sqrt{a^2+b^2} /2
Answer:
[tex]b = \sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}}[/tex]
Step-by-step explanation:
Given - The circumference of the ellipse approximated by [tex]C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }[/tex]where 2a and 2b are the lengths of 2 the axes of the ellipse.
To find - Which equation is the result of solving the formula of the circumference for b ?
Solution -
[tex]C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }\\\frac{C}{2\pi } = \sqrt{\frac{a^{2} + b^{2} }{2} }[/tex]
Squaring Both sides, we get
[tex][\frac{C}{2\pi }]^{2} = [\sqrt{\frac{a^{2} + b^{2} }{2} }]^{2} \\\frac{C^{2} }{(2\pi)^{2} } = {\frac{a^{2} + b^{2} }{2} }\\2\frac{C^{2} }{4(\pi)^{2} } = {{a^{2} + b^{2} }[/tex]
[tex]\frac{C^{2} }{2(\pi )^{2} } = a^{2} + b^{2} \\\frac{C^{2} }{2(\pi )^{2} } - a^{2} = b^{2} \\\sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}} = b[/tex]
∴ we get
[tex]b = \sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}}[/tex]
The population of a certain kind of bacteria doubles in size every 5 minutes. The current number of bacteria in the population, N, is equal to the product of the initial number of bacteria, I, and 2 to the power of n, where n is the number of times the population has doubled.
Initially, 599,737 bacteria are in a petri dish. How many bacteria are in the petri dish after 15 minutes?
A. 9,595,792
B. 4,797,896
C. 2,398,948
D. 3,598,422
Answer:
B, 4,797,896
Step-by-step explanation:
599,737 multiplied by 2 is 1,199,474 then multiplied by 2 is 2,398,948 then multiplied by 2 is 4,797,896.
I multiplied by 2, 3 times because the population of a certain kind of bacteria doubles in size every 5 minutes and 15/5=3.

Answer:
A flood
Step-by-step explanation:
Answer:
Annie is most likely to experience a flood.
Step-by-step explanation:
Her location is not specified beyond living near a river, therefore we cannot be sure of earthquakes, she does not live near a body of water large enough to cause a tsunami, and it did not specify that she was near a volcano therefore we make the assumption that she is not at risk for that. Therefore, leaving a flood as our option.

The function g(x) is described in the table below what is g(0)+g(4)?
Let's take a look at our table here in order to solve the problem. We need to know what g(0) and g(4) are to be able to solve.
Since we are plugging in x-values and looking for y-values, we simply need to find 0 and 4 on the left side of the table (the x side), and then find their corresponding g(x), or y, values.
g(0) = -5
g(4) = -4
Now, all that's left to do is add these two values.
-5 + -4
-9
Hope this helps!! :)
Answer:
- 9
Step-by-step explanation:
g(0) = - 5 ← value of g(x) when x = 0
g(4) = - 4 ← value of g(x) when x = 4
Then
g(0) + g(4) = - 5 + (- 4) = - 5 - 4 = - 9

The price of an article is increased from Rs 75 to Rs 78. Find the percentage increase in the price of the article.
WITH FULL CALCULATION PLEASE!!!!!
======================================================
Work Shown:
A = old value = 75
B = new value = 78
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (78-75)/75 ] * 100%
C = (3/75) * 100%
C = 0.04 * 100%
C = 4%
The positive C value means we have a percent increase.
The price has increased by 4%

Answer:
[tex]x\geq 2[/tex]
Step-by-step explanation:
The parent function, [tex]y=\sqrt{x}[/tex], has a domain of [tex]x\geq 0[/tex] or [tex][0, \infty)[/tex], because the value under the radical cannot be less than 0 (we cannot take the square root of a negative number). Thus, by setting everything inside the radical to 0, we can find the domain of this function:
[tex]x-2\geq 0,\\x\geq 2[/tex]
Thus this domain of this function is:
As an inequality: [tex]x\geq 2[/tex] (desired in problem)
In interval notation: [tex][2, \infty)[/tex]

ADD root of 5 +2 root of 2 and root of 2 - 5root of 3
Add :
→ (√5 + 2√2) & (√2 - 5√3)
Putting the sign of plus at the place of &.→ (√5 + 2√2) + (√2 - 5√3)
Removing the brackets.
→ √5 + 2√2 + √2 - 5√3
→ √5 + (2 + 1)√2 - 5√3
→ √5 + 3√2 - 5√3
Therefore, the required answer is √5 + 3√2 - 5√3.

You are building a ramp that must cover a horizontal distance of exactly 17 feet. The angle of the ramp from the ground is 24°. Determine the length of the ramp, in feet.
The length of the ramp is 6.91 feet
Given data:
To determine the length of the ramp, we can use trigonometry. So, use the sine function, which relates the angle of the ramp to the ratio of the opposite side (length of the ramp) to the hypotenuse (the distance the ramp covers).
Given that the angle of the ramp is 24°, set up the equation:
sin(24°) = opposite/hypotenuse
The opposite side is the length of the ramp and the hypotenuse is the distance it covers, which is 17 feet.
sin(24°) = length of the ramp / 17
To find the length of the ramp, rearrange the equation:
The length of the ramp = sin(24°) * 17
L ≈ 6.91 feet
Hence, the length of the ramp is approximately 6.91 feet.

f(x) = -8 (5-x), what is the value of f(-4)?
Answer:
f(-4) is basically just saying that you need to use the function given while x = -4.
The function given:
f(x) = -8(5-x)
We see that f(-4) means that x has to be -4, so we can substitute it in:
f(-4) = -8(5-(-4))
f(-4) = -8(9)
f(-4) = -72
Therefore, f(-4) is -72.

Answer:
x = 11.25
Step-by-step explanation:
The sum of the angles is 90 degrees since it is a right angle

Divide each side by 8
8x/8 =90/8
x =11.25
Suppose the two measures of a center are 82.5 degrees and 83.6 degrees. Which value is the median?
A. 82.5
B. 83.6
Answer:
83.05
Step-by-step explanation:
The two measures of the center are 82.5 and 83.6
The value of the median can be calculated a follows
= 82.5 + 83.6/2
= 166.1/2
= 83.05
Hence the value of the media is 83.05
