Use the function below to find F(2).<br> F(t) = 2•1/2^3t

navik [9.2K]

Answer:

$F(2)= \frac{1}{32}$

Step-by-step explanation:

The given function is

$F(t) = 2 \cdot \: \frac{1}{{2}^{3t} }$

To find F(2), we substitute t=2 into the function.

This means that wherever we see t, we put 2

$F(2) = 2 \cdot \: \frac{1}{{2}^{3 \times 2} }$

We multiply the exponent in the denominator to get:

$F(2) = 2 \cdot \: \frac{1}{{2}^{6} }$

We evaluate to get:

$F(2) = 2 \cdot \: \frac{1}{64}$

We now cancel the common factors to get:

$F(2) = \frac{1}{32}$

Enter the equation in y=mx form to find the m as the slope

Morgarella [4.7K]

Answer:

Step-by-step explanation:

look at the points that are intersected by the line. the first one is (2,8). put it in as Rise/Run to find the slope. you "rise" 8, and "run" 2

so 8/2 is the slope.

usually you need to simplify it.

8/2 = 4

Please help me asap!

Artemon [7]

Answer: 1. ∠A= 80.75° 2. 41.79 $cm^2$

Step-by-step explanation:

Since, According to the sines low,

$\frac{sin A}{CB} = \frac{sin C}{AB}$

Here, CB= 4.1 cm, AB = 3.3 and ∠ C = 52.6°

$\frac{sin A}{4.1} = \frac{sin 52.6}{3.3}$

⇒ $sin A = 4.1\times\frac{sin 52.6}{3.3}$

⇒ $sin A =0.98699998308$

⇒ A = 80.75°

2. Since, the area of the given figure = Area of the rectangle having dimension 8.3 × 4.2 + Area of the half square of radius 2.1

=34.86 + 6.93

= 41.79 square cm

What is 3% of $30.00?

CaHeK987 [17]

% means out of 100 so 1%=1/100

so 3%=3/100
$30.00=3000 cents
so you multiply 3/100 by 3000 =(3*3000)/100
you can cross out two zeros at the bottom and on the top and get
(3*30)/1 or 90/1 or 90 cents
