Ella bought 8 meters of ribbon for $10.

Zanzabum

Answer:

$0.03 per inch

Step-by-step explanation:

We need to convert 8 meters to inches first.

Unit ratio for meters to cm is:

$\frac{1m}{100cm}$

So 8 meters is 800 cm

Now,

we need to convert 800 cm to inches

Unit ratio for cm to inches is:

$\frac{2.54cm}{1inch}$

So, 800 cm is :

$\frac{800}{2.54}=314.96$ inches

To get costing per inch, we divide total cost ($10) by the total number of inches (which is 314.96):

$\frac{10}{314.96}=0.032$

Rounded to nearest hundredth, $0.03 per inch

Angle A is circumscribed about circle O what is the length of AB

Nana76 [90]

Answer:

$AB \approx 4.054$

Step-by-step explanation:

The trigonometric equations associated with the figure are, respectively:

$AB = 4\cdot \cos 73^{\circ} + 3\cdot \cos \alpha$

$4\cdot \sin 73^{\circ} = 3 +3\cdot \sin \alpha$

The components with the unknown angle are cleared and used in the fundamental trigonometric relation:

$3\cdot \cos \alpha = AB - 4\cdot \cos 73^{\circ}$

$3\cdot \sin \alpha = 4\cdot \sin 73^{\circ} - 3$

$9\cdot \cos^{2}\alpha + 9\cdot \sin^{2}\alpha =(AB-4\cdot \cos 73^{\circ})^{2}+(4\cdot \sin 73^{\circ}-3)^{2}$

$9 = AB^{2}-2.339\cdot AB + 1.368 + 0.681$

The following second-order polynomial is presented below:

$AB^{2}-2.339\cdot AB -6.951 = 0$

Roots of the polynomial are described hereafter:

$AB_{1} \approx 4.054$ and $AB_{2} \approx -1.715$

Only the first root is reasonable, as length is a positive variable. The length is $AB \approx 4.054$ .

Complete the steps in order to write the inverse of f(x) = x + 5

yaroslaw [1]

An inverse function produces points (y,x) for every point (x,y) produced by the parent function. So to find the inverse function, you solve for the independent variable and when done switch the variable labels....

y=x+5 subtract 5 from both sides

y-5=x now switch labels

y=x-5

So if f(x)=x+5

f^-1(x)=x-5

(WILL GIVE BRAINLIEST) Describe how you would simplify the given expression.

Vinil7 [7]

Answer:

Simplify inside the parentheses by dividing coefficients, subtracting the exponents on like bases, and raising the resulting expression to the –3 power. Then, write bases with positive exponents.

Raise the numerator and denominator to the –3 power. Then, using the power of a power property, multiply the exponents. Divide the coefficients and subtract the exponents on like bases, then write with positive exponents.
