Answer:

1.98

Step-by-step explanation:

In this problem, we are:

Given: ∠D = 26°, Hypotenuse (DF) = 4.5

To solve: EF

Now through the given, we are to focus on point D to solve for EF.

We need to find the relationship of point D to DF and EF.

The relationship here is sine.

Reason: \frac{opposite}{hypotenuse}

Through point D, DF is the hypotenuse and EF is the opposite side.

So let's solve this simply through algebra,

sin = \frac{opposite}{hypotenuse}

sin(26°) = \frac{EF}{4.5}

0.44 = \frac{EF}{4.5}

0.44 × 4.5 = EF

1.98 = EF

A)9-8i

Explanation

9-\sqrt[]{-64}

Step 1

Let's remember that

A complex number is an object of the form

a+bi

where a and b are real numbers and

\begin{gathered} i^2=-1 \\ i=\sqrt[]{-1} \end{gathered}

so

\begin{gathered} 9-\sqrt[]{-64} \\ 9-\sqrt[]{-1\cdot64} \\ 9-\sqrt[]{-1}\sqrt[]{64} \\ 9-8\sqrt[]{-1} \\ 9-8i \end{gathered}

therefore, the answer is

A)9-8i

I hope this helps you

What is the vertex of f(x) = | 8x + 8| - 3?
Harman [31]

Answer:

<h2>(-1, -3)</h2>

Step-by-step explanation:

Vertex of y = |x| have the coordinates (0, 0).

f(x) + n - shift the graph n units up

f(x) - n - shift the graph n units down

f(x + n) - shift the graph n units to the left

f(x - n) - shift the graph n units to the right

nf(x) - stretches/shrinks vertically

f(nx) - stretches/shrinks horizontally

We have

f(x) = |8x + 8| - 3 = |8(x + 1)| - 3 = |8| · |x+1| - 3 = 8|x + 1| - 3

g(x) = |x| → f(x) = 8g(x + 1) - 3

vertically streched by 8      (0, 8 · 0) → (0, 0)

shifted 1 unit to the left    (0 - 1, 0) → (-1, 0)

shifted 3 units down       (-1, 0 - 3) → (-1, -3)
