Answers

Answer:

b

Step-by-step explanation:

just took the test edg 22

Option B is correct, -5.5 is the zero of the quadratic function f(x) = 4x + 24x + 11

What is quadratic equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

The given quadratic function is f(x) = 4x²+24x+11

We have to find the zero of the function.

Let us use the quadratic formula to find the zero.

a=4, b=24 and c=11

Let us plug in these values in quadratic formula

x=- 24±√24²-4(4)(11)/8

=-24±√576-176/8

=-24±√400/8

=-24±20/8

=4(-6±5)/8

=(-6+5)/2  or -6-5/2

=-1/2 or -11/2

=-0.5  or -5.5

Hence, Option B is correct, -5.5 is the zero of the quadratic function f(x) = 4x + 24x + 11

If LN = 12x + 16, what is the length of Line segment L N in units?

Answers

Answer:

Step-by-step explanation:

16 units 40 units 48 units 64 units.

Answer:

64 units

Step-by-step explanation:

Given M lies on LN, so LN = LM + MN --------------(1)

LN = 12x + 16

LM = 10x + 8

MN = 5x - 4

Substituting the values in equation 1, we get:

12x + 16 = (10x + 8) + (5x - 4)

12x + 16 = 15x + 4

15x - 12x = 16 -4

3x=12

Therefore x=4

LN= 12(4) + 16 = 64 units

If you deposit 4,300 into an account with an semi annual interest rate of 11% how much will you have after 1year

Answers

Answer:

FV= $4,786.01

Step-by-step explanation:

Giving the following information:

Initial deposit (FV)= $4,300

Number of periods (n)= 2 semesters

First, we need to calculate the semi-annual interest rate:

Semi-annual interest rate= 0.11/2= 0.055

Now, to determine the future value, we need to use the following formula:

FV= PV*(1+i)^n

FV= 4,300*(1.055^2)

FV= $4,786.01

A caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes. How fast does the caterpillar move in feet per minute? ​

Answers

Given:

A caterpillar moves across the grass at a rate of [tex]4\dfrac{2}{3}[/tex] feet every 7 minutes.

To find:

The rate of moving caterpillar in feet per minute.

Solution:

We have,

Distance covered by caterpillar is 7 minutes = [tex]4\dfrac{2}{3}[/tex] feet

Distance covered by caterpillar is 1 minutes = [tex]\dfrac{4\dfrac{2}{3}}{7}[/tex] feet

                                                                        = [tex]\dfrac{\dfrac{4(3)+2}{3}}{7}[/tex] feet

                                                                        = [tex]\dfrac{14}{3\times 7}[/tex] feet

                                                                        = [tex]\dfrac{2}{3}[/tex] feet

Therefore, caterpillar move [tex]\dfrac{2}{3}[/tex] feet per minute.

It's a great word that conjures visions of slime and unpleasantness. It is perhaps the most annoying part of having a cold or allergies. Mucus, however, plays a very important role in defense of our bodies and our health. In fact, it's high time mucus got a lot more respect.First, there are some amazing facts about mucus that are worthy of respect. Humans produce about a liter of mucus every day, whether they are sick or not. Bony fish and some invertebrates (snails or slugs) also have mucus cells on the outside of their body. This external mucus creates a protective coating that prevents predators' toxins from doing harm. Humans produce mucus to protect our stomachs, our lungs, and several other systems.We tend to not like mucus because it is a considered a symptom or sign that something is wrong. We usually only see it when we are sick, and so we tend to dislike it. According to Michael M. Johns, III, MD, however, "mucus is incredibly important for our bodies." Johns, an assistant professor at Emory University, calls mucus "the oil in the engine" of our bodies. Without mucus, our engines, or bodies, would freeze up and stop working properly.Furthermore, mucus is not just the nasty gunk you see when you are sick. It lines the tissues in your mouth, your nose, throat, and lungs. It also is crucial in protecting your digestive system. Mucus puts a protective coating over the surfaces of these tissues, keeping them moist. Most of the time we don't notice mucus is making our lives better. It does its job quietly, making everything run smoothly, keeping our inner tissues soft and flexible enough to fight off invaders.Occasionally, though our mucus-making membranes go into overdrive. If you eat a hot pepper, your mucus membranes in your mouth and throat start producing extra mucus to protect you. If you come into contact with pollen, you may get a runny nose and start sneezing and coughing. When these things happen, your mucus systems start making more fluids to wash away the irritating particles. Mucus also has some antibodies that increase our ability to fight off bacteria and viruses.It's hard to appreciate what is essentially slime, but we have mucus for some very good reasons. It helps to keep us healthy and lets us know when our bodies are under attack. We would be wise to respect what our bodies do to keep us safe. So the next time you find yourself reaching for a tissue, remember mucus is your friend and ally.Which line from the text explains people's attitude about mucus? (1 point) aIf you eat a hot pepper, your mucus membranes in your mouth and throat start producing extra mucus to protect you. bHumans produce mucus to protect our stomachs, our lungs, and several other systems. cWe tend to not like mucus because it is a considered a symptom or sign that something is wrong. dIt does its job quietly, making everything run smoothly, keeping our inner tissues soft and flexible enough to fight off invaders. can anyone please help me
