Simplify the following:
(1 + 1/2) (2 + 1/4)×4
Put 1 + 1/2 over the common denominator 2. 1 + 1/2 = 2/2 + 1/2:
(2/2 + 1/2) (2 + 1/4)×4
2/2 + 1/2 = (2 + 1)/2:
((2 + 1)/2) (2 + 1/4)×4
2 + 1 = 3:
3/2 (2 + 1/4)×4
Put 2 + 1/4 over the common denominator 4. 2 + 1/4 = (4×2)/4 + 1/4:
(3×4)/2 ((4×2)/4 + 1/4)
4×2 = 8:
(3 (8/4 + 1/4)×4)/2
8/4 + 1/4 = (8 + 1)/4:
(3×4)/2 ((8 + 1)/4)
8 + 1 = 9:
3/2×9/4×4
3/2×9/4×4 = (3×9×4)/(2×4):
(3×9×4)/(2×4)
(3×9×4)/(2×4) = 4/4×(3×9)/2 = (3×9)/2:
(3×9)/2
3×9 = 27:

Which of the following statements are true about the given rational equation? check all of the boxes that apply. 4 x 6 1 x2 = x 10 x3 6x2 x = 1 is a solution. x = 0 is a solution. x = –1 is a solution. x = –6 is a solution.
We can actually see that the statements that are true are:
A. x = 1 is a solution.
C. x = –1 is a solution.
What is rational equation?Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.
We can see then that:
[tex] \frac{4}{x + 6} + \frac{1}{ {x}^{2} } = \frac{x + 10}{ {x}^{3} + 6 {x}^{2} } [/tex]
It's clear that: x ≠ 0 and x ≠ -6.
Looking for the LCM of the left hand side, we will have:
[tex] \frac{4}{x + 6} + \frac{1}{ {x}^{2} } = \frac{4 {x}^{2 } + (x + 6)}{(x + 6) {x}^{2} } [/tex]
So, we will see that left hand side and right hand side are equal.
[tex]4 {x}^{2} + x + 6 = x + 10[/tex]
[tex]4 {x}^{2} = 10 - 6[/tex]
[tex]4 {x}^{2} = 4[/tex]
[tex] {x}^{2} = 1[/tex]
[tex] x = 1[/tex]
or
[tex]x = - 1[/tex]
So, we can see that options A and C are correct.

1=10^0 into logarithmic form
Answer:
[tex]0 = log_{10} 1[/tex]
Step-by-step explanation:
Base for the exponent and for the logarithm are the same!
10^0 is the exponential form where 10 is the base and 0 the exponent
[tex]log_{10} 1[/tex] is the logarithm form where 10 is the base
To solve [tex]log_{10} 1 =[/tex] ask the question :
To what power should I raise the base 10 to obtain the number 1 ?
The answer to the power 0 therefore
[tex]log_{10} 1 = 0[/tex]

Which shows the terms of the series? 4 12 48 192 4 12 36 3 12 48 192 3 12 48
The value of the term in the series will be equal to 3 + 12 +48 + 192 after calculation.
What is summation?In mathematics, the summation is the addition of a sequence of any kind of numbers, called addends or summands.
Now we have a given term
[tex]\sum_{n=1}^{4} 3(4)^{n-1}[/tex]
By solving the above term;
[tex]\sum_{n=1}^{4} 3(4)^{n-1}=3(4)^{1-1}+3(4)^{2-1}+3(4)^{3-1}+3(4)^{4-1}[/tex]
[tex]\sum_{n=1}^{4} 3(4)^{n-1}=3(4)^0+3(4)^1+3(4)^2+3(4)^3[/tex]
[tex]\sum_{n=1}^{4} 3(4)^{n-1}=3 + 12 +48 + 192[/tex]
Hence the value of the term in the series will be equal to 3 + 12 +48 + 192 after calculation.

Answer:
Step-by-step explanation:
the 2nd and 4th answers look good. the 1st answer is correct as well.
To solve this look at the x axis and y axis, the x axis is in inches, the y axis is in pounds. So you know that as the distance increase per inch, the force in pounds is increasing too.
so the force applied is going up, 0.73 pounds , for each inch of travel ( or stretch) of the spring.

enter the value of c when the expression 21.2x + c is equivalent to 5.3(4x - 2.6).
Answer:
c = -13.78.
Step-by-step explanation:
21.2x + c ≡ 5.3(4x - 2.6)
21.2x + c ≡ 21.2x - 13.78
Equating constant terms:
c = -13.78.
Answer:
13.78
Step-by-step explanation:
21.2x + c = 5.3(4x - 2.6)
open the bracket
21.2x + c = 21.2x - 13.78
collect like terms
c + 13.78 = 21.2x - 21.2x
c + 13.78 = 0
c = -13.78
The circumference of a compact disc is 28.26 centimeters. What is the radius?
Please help
Answer:
The radius is 4.5cm.
Step-by-step explanation:
Circumference is the distance around the outside of a circle, the perimeter of the circle. Circumference formula is:
C = pi•d OR
C = 2•pi•r
Since we are looking for radius, use the second formula.
C = 2•pi•r
28.26 = 2pi•r
Divide by 2pi.
28.26/2pi = r
r = 4.5
The radius is 4.5 cm.

If y varies directly with x and
y=15 when x is 9, what is x when
y=30?
Answer:
x = 18
Step-by-step explanation:
given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
to find k use the condition y = 15 when x = 9 , then
15 = 9x ( divide both sides by 9 )
[tex]\frac{15}{9}[/tex] = x , that is
x = [tex]\frac{5}{3}[/tex]
y = [tex]\frac{5}{3}[/tex] x ← equation of variation
when y = 30 , then
30 = [tex]\frac{5}{3}[/tex] x ( multiply both sides by 3 to clear the fraction )
90 = 5x ( divide both sides by 5 )
18 = x

9. What is the vertex of the function? f(x) = 3x² - 8x + 10
Answer:
The vertex of the function is (1.333, 4.667)
Step-by-step explanation:
1. Calculate -b / 2a. This is the x-coordinate of the vertex.
2. simply plug -b / 2a into the equation for x and solve for y.
[tex]Y = 3x^{2} - 8x + 10\\Compare with the form of y = ax^{2} + bx + c\\So that means a = 3, b = -8, and c = 10.[/tex]
Calculate -b/2a:
[tex]X = -(-8)/2(3)[/tex]
[tex]X = 8/6[/tex]
This is equal to 1.33 recurring
Plug 8/6 for x and solve for y:
[tex]Y = 3x^{2} - 8x + 10[/tex]
[tex]Y = 3(\frac{8}{6})^{2} - 8(\frac{8}{6}) + 10[/tex]
[tex]Y = \frac{48}{9} - \frac{64}{6} + 10\\[/tex]
This is equal to 4.66 reccuring.

• 1 hour = 60 minutes
• 1 kilometer = 1000 meters
• 1 mile = 1.6 kilometers
Calvin biked 24 miles in 2 hours. What is his approximate
average speed in meters per minute?
1 mile = 1.6 kilometers so 24*1.6 = 38.4
24 miles = 38.4 kilometers
1 kilometer = 1000 meters so 38.4*1000 = 38,400 meters
38.4 kilometers = 38,400 meters
1 hour = 60 minutes so 2*60 = 120
2 hours = 120 minutes
To calculate meters per minute, divide.
38,400 / 120 = 320
So that means that Calvin's approximate speed is 320 meters per minute.
