Answer:

The ratios are both identical

Step-by-step explanation:

sin(x)=opposite/hypotenuse=4/5

cos(y)=adjacent/hypotenuse=4/5

Therefore, the ratios are both identical.

The area of a rectangular rug is 14 1/12 square yards. The length of the rug is 4 1⁄3 yards. What is the width?
Harlamova29_29 [7]

Answer:

w=3 1\4

Step-by-step explanation:

A=LxW

a=14 1\12

l=4 1\3

w=?

14 1\12=4 1\3 x w

14 1\12 divided by 4 1\3=13\4=3 1\4

w=3 1\4

For what value of x will the function f(x) = -3(x - 10)(x - 4) have a maximum value? Find the maximum value.
gayaneshka [121]

Hello!

To find the maximum value of the function f(x) = -3(x - 10)(x - 4), the easiest way is to find the vertex using the formula: x = -b/2a.

Firstly, we need to simplify f(x).

f(x) = -3(x - 10)(x - 4)

f(x) = -3(x² - 14x + 40)

f(x) = -3x² + 42x + -120

Since the equation f(x) is now simplified to standard form, we can find the vertex.

a = -3, b = 42, and c = -120

x = -(42)/2(-3) = -42/-6 = 7

Then, we substitute 7 into the the function f(x) = -3(x - 10)(x - 4), or

f(x) = -3x² + 42x + -120, to find the y-value of the vertex.

f(x) = -3(7 - 10)(7 - 4)

f(x) = -3(-3)(4)

f(x) = 27

The vertex of f(x) is (7, 27).

Therefore, the maximum x-value for the function f(x) is 7.

9f + 10f - 12f I need help fam
mixer [17]

Since these are all like terms, you're essentially just adding and subtracting here.

9f + 10f -12f

Add 9f and 10f.

9f + 10f = 19f

Then, subtract.

19f - 12f = 7f

Your answer is 7f.
