Answer:
Step-by-step explanation:
1)
We know that if [tex]x^2=9[/tex], then [tex]x=\pm \sqrt{9}[/tex], so [tex]\boxed{x=3,-3}[/tex]
2)
We know that if [tex]x^3=8[/tex], then [tex]x=\sqrt[3]{8}[/tex], so [tex]\boxed{x=2}[/tex]
3)
[tex]x^3=\frac{1}{8}[/tex] means that [tex]x=\sqrt[3]{\frac{1}{8}}=\frac{\sqrt[3]{1}}{\sqrt[3]{8}}=\frac{1}{2}[/tex].
So, [tex]\boxed{x=\frac{1}{2}}[/tex].
4)
[tex]x^3=27[/tex] means that [tex]x=\sqrt[3]{27}=\sqrt[3]{3^3}=3[/tex].
So, [tex]\boxed{x=3}[/tex].
5)
[tex]x^2=25[/tex] means that [tex]x=\pm \sqrt{25}=\pm \sqrt{5^2}=\pm 5[/tex].
So, [tex]x=5,-5[/tex].
6)
We know that the side length of the square will be [tex]\sqrt{\frac{9}{16}}=\frac{\sqrt{9}}{\sqrt{16}}=\boxed{\frac{3}{4}}[/tex].
7)
[tex]6x^2=54[/tex] means that [tex]x^2=9[/tex], which means that [tex]\boxed{x=3,-3}[/tex].
8)
[tex]2x^2+25=75[/tex] means that [tex]2x^2=50[/tex], which means that [tex]x^2=25[/tex], which means that [tex]\boxed{x=5,-5}[/tex]

Determine the center and radius of the circle described by the equation. (x+1)2+(y−3)2=25
Answers
Answer: 2 (x + y) = 29
2 (x + y - 2) = 25
y = 29/2 - x
Expanded forms:
2 x + 2 y - 4 = 25
2 x + 2 y - 29 = 0
Real solution:
y = 29/2 - x
Solution:
y = 29/2 - x
Solution for the variable y:
y = 1/2 (29 - 2 x)

Evaluate the expression. 1/7^9⋅1/7^−6 The value of the expression is .
Answers
Answer:1/343
Step-by-step explanation:
you can use the exponent rule so you would be left with (1/7)^9-6 which would simplify to (1/7)^3. The if you not using a calulater, you can take 1/7 and individually cube the numbers to find the final answer. So 1^3/7^3. This would simplify to 1/7^3. 7^3 is 343. This leaves you with the final answer.

The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1200 hours and a standard deviation of 35 hours. Using the empirical rule, determine what interval of hours represents the lifespan of the middle 68% of light bulbs.
Answers
Answer:
(1165, 1235) (hours)
Step-by-step explanation:
The "middle 68%" of a set of normally distributed data is that data that lies within ONE standard deviation of the mean:
(1200 - 35, 1200 + 35), or
(1165, 1235) (hours)
This is an application of the Empirical Rule.
The interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).
What is the standard deviation?It is a measurement of statistical data dispersion. The degree to which the value varies is known as dispersion.
With a mean of 1200 hours and a standard variation of 35 hours, the length of time a certain brand of light bulb lasts is typically distributed.
The data that is within one standard deviation of the mean is referred to as the "middle 68 percent" of a collection of normally distributed data:
The interval of hours represents the lifespan of the middle 68% of light bulbs is found as;
(1200 - 35)=1165
( 1200 + 35)=1235
(1165, 1235) (hours)
Hence,the interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).

what are the solutions to the expression x^2-8x=24
Answers
Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)
Step-by-step explanation:
x^2-8x=24 <- subtract 24 from both sides
x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a
-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify
(-(-8) +/- 4sqrt(10) )/2 <- sepereate
(-(-8) +/4sqrt(10) )/2 , (-(-8) - 4sqrt(10) )/2 <- simplify
2(2+sqrt(10)) , 2(2-sqrt(10) =x
