So BC is 2x+1 and they are telling you that if your x is 5 then what is BC
So you have to plug in the 5 into your equation
2(5)+1
10+1
11
So BC is 11

Given: Triangle ABC, mmBC=24 cm, line segment AL- < bisector
Furkat [3]

The value of line AL is 21. 51cm

<h3>How to determine the length</h3>

To find line AL,

Using

Sin α = opposite/ hypotenuse to find line AB

Sin 90 = x/ 24

1 = x/24

Cross multiply

x = 24cm

Now, let's find line AC

Sin angle B = line AC/24

Note that to find angle B

angle A + angle B + angle C = 180

But angle B = 2 Angle A

x + 2x + 90 = 180

3x + 90 = 180

3x = 180-90

x = 30°

Angle B = 2 × 30 = 60°

Sin 60 = x/ 24

0. 8660 = x/24

Cross multiply

x = 24 × 0. 8660

x = 20. 78cm

We have the angle of A  in the given triangle to be divide into two by the bisector, angle A = 15°

To find line AL, we use

Cos = adjacent/ line AL

Cos 15 = 20. 78/ line AL

Line AL = 20. 78/ cos 15

Line AL = 20. 78 / 0. 9659

Line AL = 21. 51 cm

Thus, the value of line AL is 21. 51cm

Which statement BEST describes the growth of bacteria modeled by the function f(x)=1.8x
lara [203]

Answer:


Step-by-step explanation:

f(x) = 1.8x is a linear function and does not model the growth of bacteria.  Perhaps you meant f(x) = 1.8^x, which is an exponential function whose initial value is 1.  Please ensure that you have copied down this problem exactly as it was presented.

If 5ex = 300, x = A) ln (300) = 5.703 . . . B) 5 ln (60) = 20.471 . . . C) ln (300)∕5 = 1.140 . . . D) ln (60) = 4.094 . . .
tino4ka555 [31]

Answer:

D) ln (60) = 4.094...

Step-by-step explanation:

Let's solve for x

We'll be careful because it's exponential.

5ex = 300

ex= 300/5

ex= 60

x = e^-1(60)

Let's note that this expression e^-1 is equal to In

x= In (60)

x = 4.0943

So the value of x is equal to 4.0943

Thank you.
