Which choice is equivalent to the quotient shown here when x is greater than or equal to 0?

Dima020 [189]

Answer: OPTION C

Step-by-step explanation:

Remember that:

$\sqrt[n]{a^n}=a$

And the Product of powers property establishes that:

$a^m*a^n=a^{(mn)}$

Rewrite the expression:

$\frac{\sqrt{18x} }{\sqrt{32} }$

Descompose 18 and 32 into their prime factors:

$18=2*3*3=2*3^2\\32=2*2*2*2*2=2^5=2^4*2$

Substitute into the expression, then:

$\frac{\sqrt{(2*3^2)x} }{\sqrt{2^4*2} }$

Finally,simplifying, you get:

$\frac{3\sqrt{(2)x} }{2^2\sqrt{2} }=\frac{3\sqrt{2x}}{4\sqrt{2}}=\frac{(3)(\sqrt{x})(\sqrt{2})}{(4)(\sqrt{2})}= \frac{3\sqrt{x}}{4}$

Clara estimates that the length of a hiking trail is 5.75 km. She later learns that its actual length is 6.25 km. What is the pe

Hunter-Best [27]

Percent error : (approximate value - exact value) / exact value.....x 100

percent error : (5.75 - 6.25) / 6.25......ignore any negative signs
0.5 / 6.25 = 0.08.....x 100 = 8% error <==

Rearrange the equation so r is the independent variable. 10q - 5r = 30

Murljashka [212]

Answer:

q = 3 + 1/2r

Step-by-step explanation:

10q - 5r = 30

We want to solve for q

Add 5r to each side

10q - 5r+5r = 30+5r

10q = 30+5r

Divide by 10

10q/10 = 30/10 +5r/10

q = 3 + 1/2r

Enter the patriot equivalent to Tan (A) And Enter the ratio equivalent to cos (B)

PolarNik [594]

Answer:

$(a)\ \tan A = \frac{5}{12}$

$(b)\ \cos B = \frac{5}{13}$

Step-by-step explanation:

Given

See attachment for triangles

Solving (a)

$\tan(A)$

The tan of an angle is:

$\tan(\theta) = \frac{Opposite}{Adjacent}$

From the given triangle.

$Opposite = 5$

$Adjacent = 12$

So, we have:

$\tan A = \frac{5}{12}$

Solving (b)

$\cos(B)$

The cos of an angle is:

$\cos(\theta) = \frac{Adjacent}{Hypotenuse}$

From the given triangle.

$Adjacent = 5$

$Hypotenuse = 13$

So, we have:

$\cos B = \frac{5}{13}$
