What kinds of things do firefighters need to carry?What do you think this means for the angle of the ladder they’re willing or able to climb?

Answers

Answer:

Given

Step-by-step explanation:

A firefighter needs to carry an LED flashlight, a knife or axe, a wax pencil. Every firefighter will put these to use regularly. Two other essential items are dust masks and earplugs. In addition to this they require fire protective gear and clothes.

The angle of the ladder is suitable to be around 75° for rescue operations and for firefighters to climb and perform tasks effectively.

Hope this is helpful..

If f(x) = x2 + 2x + 3, what is the average rate of change of f(x) over the interval [-4, 6]? A. 51

B. 40

C. 31

D. 20

E. 4

Answers

Calculating the value of f(x) for the given interval.

For x = - 4, f(x) = f(- 4) = (- 4)^2 + 2 (- 4) + 3 = 11

For x = 6, f(x) = f(6) = (6)^2 + 2 (6) + 3 = 51

Now using formula for the calculation of average rate of change of f(x) over the given interval of [- 4, 6];

(f(b) – f(a)) / b – a = (f(6) – f(- 4)) / 6 – (- 4) = (51 -11) / 10 = 4

So option “E” is correct.

Help plz i will make u a brainllest 24.Can you use the SSS Postulate or the SAS Postulate to prove abd=dca? 26 28

Answers

Answer: 24) C. SSS only

26) D. DH = HF

Step-by-step explanation:

24.

Statement Reason

1. BD = CA 1. Given

2. AB = CD 2. Given

3. AD = AD 3. Reflexive Property

4. ΔABD = ΔDCA 4. SSS Congruency Theorem

We have no information about the angles so cannot use SAS Theorem.

26. G H F

E H D

Line up the letters to find the congruent sides:

⇒ GH = EH

HF = HD

GF = ED

If bc = 8.3 cd = 6.7 and ad = 11.6 find ab to the nearest tenth

Answers

This is going to be tricky to explain over text, so try to bear with me :)

You have the information given above. Let's start with just ad = 11.6 for now. since these are variables, it can also be understood be understood as a times d= 11.6.
Knowing this, we can figure out that d = 11.6/a, when you divide both sides by a.

You now have d, so plug (11.6/a) into cd=6.7. You have to do the same thing you did last time, except this time you are aiming to get c by itself. So, multiply both sides by a/11.6 and you get c = (6.7a)/ 11.6.

Guess what, you know c now! so you put (6.7a)/11.6 in for c in the equation given to you earlier, bc =8.3. The math gets a bit messy here, but you basically solve for b here, which, when you crunch the numbers down, ends up being ~14.3705 divided by a. You are looking for ab, so just multiply both sides by a, and round to the nearest tenth so that you have ab= 14.4

How many gallons of water will it take to fill a tank measuring 8' long 28" wide and 3' deep

Answers

You're looking for the volume function here. V=LWH

In this case the length is 8 feet
L=8
Width is 28 inches, and since there's twelve inches in a foot, it's 28/12 feet
W=28/12=2 $(1)/(3)$
Height, or in this case depth, is 3 feet
H=3

V=LWH
V=(8)(2 $(1)/(3)$ )(3)
V=56ft $^(3)$

Now you know how many cubic feet are in your tank. There are just around 7.5 gallons in a cubic foot. An estimated answer then would be the volume times 7.5

56·7.5=420

There's an estimated answer. If you need exact EXACT, then using the exact amounts and everything the answer comes out to 418.909 gallons.
