Answer:

The formula to get the circumference of a circle is $C=2*\pi * r$ . We can then input the value and we get that $C=2*\pi*3.3$ and as we solve it more the final answer that we get is $C=20.735$ .

Two rectangles have the same area of 24cm².The second rectangle is 4cm shorter and 1cm wider than the first.What is the length a

lukranit [14]

Answer:

First rectangle: 12 cm by 2 cm

Second rectangle: 8 cm by 3 cm

Step-by-step explanation:

You can examine factor pairs of 24 to see which pairs meet the requirements:

24 = 1×24 = 2×12 = 3×8 = 4×6

Factor pairs (2, 12) and (3, 8) have one factor that differs by 1 and another factor that differs by 4. We can use these numbers to describe the rectangles:

First rectangle: 12 cm by 2 cm

Second rectangle: 8 cm by 3 cm

Using the digits 0 to 9 at most one Time each,fill in the boxes below to write equations whose solution is 1/2

andrezito [222]

Answer:

The equation is 4x + 5 = 2x + 6

Step-by-step explanation:

The solution is $\frac{1}{2}$ means x = $\frac{1}{2}$

Let us put the coefficient of x in the left hand side = 4 and the coefficient of x in the right hand side = 2

∵ 4x - 2x = 2x

Now we need two numerical terms their difference is 1 like 5 and 6 or 6 and 7 or 7 and 8 or 8 and 9

Let us take 5 and 6

∵ 4x + 5 = 2x + 6

- Subtract 2x from both sides

∴ 2x + 5 = 6

- Subtract 5 from both sides

∴ 2x = 1

- Divide both sides by 2

∴ x = $\frac{1}{2}$

∴ The solution is $\frac{1}{2}$

The equation is 4x + 5 = 2x + 6

I need help with this practice problem solving This is trigonometry from my ACT prep guide

Novay_Z [31]

Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:

$f(x)=A\cos (\frac{2\pi}{T}x)+b$

In the given case, you have:

A = 4

T = 3π/4

b = -3

By replacing you obtain:

$\begin{gathered} f(x)=4\cos (\frac{2\pi}{\frac{3\pi}{4}}x)-3 \\ f(x)=4\cos (\frac{8}{3}x)-3 \end{gathered}$

Hence, the answer is:

f(x) = 4cos(8/3 x) - 3

What is the value of this expression?

Zepler [3.9K]

Answer:

-3

Step-by-step explanation:

Step 1: Solve (-2+(-1))^2/3 3

1. -2+(-1) = -3

2. (-3)^2 = 9

3. 9/3 = 3

Step 2: Solve (-4)^2-17 -1

1. 3/-1

Step 3: Simplify 3/-1 = -3. I hope this helped and please don't hesitate to reach out with more questions!
