Which rational exponent represents a square root?
A. 1 / 2
B. 3/2
C. 1/3
D. 1/4
Answer:
1/2 rational exponent represents a square root.
Therefore, option A is correct.
Step-by-step explanation:
As we know that raising to the one-half power i.e. [tex]\frac{1}{2}[/tex] is the same
as taking the square root.
so [tex]x^{\frac{1}{2}}[/tex] is the same as the square root of [tex]x[/tex].For example, taking the square root of 4 will determine:
[tex]4^{\frac{1}{2}}[/tex]
[tex]\mathrm{Factor\:the\:number:\:}\:4=2^2[/tex]
[tex]4^{\frac{1}{2}}=\left(2^2\right)^{\frac{1}{2}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]
[tex]\left(2^2\right)^{\frac{1}{2}}=2^{2\cdot \frac{1}{2}}[/tex]
so the expression becomes
[tex]4^{\frac{1}{2}}=2^{2\cdot \:\frac{1}{2}}[/tex]
[tex]=2^1[/tex]
[tex]=2[/tex] ∵ [tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a[/tex]
so, 1/2 rational exponent represents a square root.
Therefore, option A is correct.
Answer: A.) 1/2 is the correct answer

a rectangle has a length of x3y4 inches and a width of xy7 inches . Which expression represents the ratio of the length of the rectangle to do width of the rectangle? (NEED HELP ASAP)
Answer:
A. x²/y³
Step-by-step explanation:
Given the following data;
Length = x³y⁴
Width = [tex] xy^{7}[/tex]
Ratio = length/width
[tex] Ratio = \frac{x^{3}y^{4}}{xy{^7}}[/tex]
Simplifying the equation by applying the law of indices (division), we have;
[tex]\frac{x^{3}}{x} = x^{3} - x^{1} = x^{3-1} = x^{2} [/tex]
[tex]\frac{y^{4}}{y^{7}} = y^{4} - y^{7} = y^{4-7} = y^{-3} [/tex]
Hence, rearranging the above values;
[tex] Ratio = \frac{x^{2}}{y^{3}}[/tex]
Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³.

8. A tire dealer sells Supreme tires for $48 each and Prestige tires for $56 each. During one week, the sales for both tires totaled $2008. If 11 Prestige tires were sold, write and solve a linear equation to find the number of Supreme tires sold.
Answer:
31 Supreme tires were sold.
Step-by-step explanation:
Cost of one Supreme tire = $45
Cost of one Prestige tire = $56
Total sales = $2008
Let x represent quantity of supreme tyre
Let y represent quantity of Prestige tyre
So, the equation will be:
[tex]45x+56y=2008[/tex]
11 Prestige tires were sold, write and solve a linear equation to find the number of Supreme tires sold.
So, we are given y= 11 and we need to find value of x using above equation
[tex]45x+56y=2008\\45x+56(11)=2008\\45x+616=2008\\45x=2008-616\\45x=1392\\x=\frac{1392}{45}\\x=30.933\\ x\approx31[/tex]
So, 31 Supreme tires were sold.

Jordan bought 4 shirts
that each cost the same
amount and I pair of
jeans that cost $40.
The items he bought cost
a total of $180 before
tax. What was the cost of
each shirt?
Answer:35 dollars each
Step-by-step explanation: Because if you take the $40 out of 180 you get 140 then you divide 140 by 4 and you get 35. Hope this helps.
Which is the correct way to check your answer for -20d=40?
A. -20/40=d
B. 40/-20=d
C. 40-20=d
D. -20d=40
Answer:
D
Step-by-step explanation:
After you get the answer then you should feel in the d with the number. Example:
-20D=40
Divide both sides by -20
D=-2
So know you should fill in d
-20(-2)=40
40=40
True

A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit. The correct option is D.
What is a complex number?A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit, and satisfies the equation i² = -1; every complex number may be represented as a + bi, where a and b are real numbers.
To find the conjugate of a complex number, we change the sign of the complex part of the number. Therefore, the conjugate of -14-2i is -14+2i.
The modulus of the given complex number -14-2i is,
|z| = √[(-14)²+(-2)²]
= √(196 + 4)
= √200
= 10√2
Hence, the conjugate and modulus of –14 – 2i are -14+2i and 10√2, respectively.
